Two worms, same brains – but one eats the other

IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.

Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.

Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.

Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.

Football: Ronaldo's own goal condemns Real Madrid to defeat

MADRID: Real Madrid's dismal season went from bad to worse when Cristiano Ronaldo scored an own goal to hand relegation-threatened Granada a shock 1-0 win on Saturday.

Real coach Jose Mourinho announced he had already given up winning the league before Christmas and this latest blow means that Barcelona can increase their lead over them to 18 points if they win away to Valencia on Sunday.

There were doubts over whether or not Ronaldo would play as he is struggling with an ankle injury and his mood didn't improve when he headed a Granada corner into his own goal after 22 minutes.

Real had scored nine goals in their last two league games but they lacked the necessary drive perhaps as a result of a draining El Clasico in midweek where they scraped a 1-1 draw in the first leg of their King's Cup tie with Barcelona.

With Iker Casillas injured, Mourinho once again put his confidence in Diego Lopez in goal rather than youth product Antonio Adan while Raphael Varane also kept his place after an inspirational performance against Barca.

It was a baptism of fire for Granada coach Lucas Alcaraz who only had a few training sessions with the team after being appointed this week with the side only a place above the relegation zone.

He decided against making sweeping changes but did play new signing Nolito from Benfica on the left wing, with Dani Benitez injured, while Diego Buonanotte, who moved from Malaga, waited his chance on the bench.

Madrid started with plenty of the ball but they were sluggish in their passing and with Granada defending in numbers they were able to close them down without any alarms.

The home side set out their stall to allow Madrid to keep possession in the middle of the pitch while Ronaldo and Angel Di Maria struggled to make any inroads down the wings and they lacked the in-form Mesut Ozil through suspension.

Inigo Lopez headed over for Granada from a corner after 13 minutes and they looked dangerous on several breaks but they lacked a quality final ball.

Eventually Carlos Aranda sent over a telling cross with the Madrid defence stretched after 20 minutes and Alvaro Arbeloa arrived just before Nolito at the far post to knock it behind.

From the resulting corner Granada took the lead as Nolito's cross was flicked into his own net by Ronaldo jumping at the near post.

Madrid offered little in response with shots from distance from Ronaldo and Xabi Alonso.

After the break a 25-yard strike from Ronaldo forced a good save from Tono Rodriguez and they gradually raised the pace of their game in the final half hour.

Substitute Karim Benzema had a glaring miss from a few yards out in the final minutes.

Earlier bottom side Deportivo La Coruna's plight got worse as they lost 3-1 away to Getafe despite going ahead through a Luis Pizzi penalty after eleven minutes and having a man extra with the dismissal of keeper Miguel Moya.

Getafe responded with a penalty of their own through Diego Costa and scored further goals from Alvaro Vazquez and Adrian Colunga while Depor's Abel Aguilar was also sent off in the second half.

Osasuna moved out of the relegation zone with a 1-0 win over Celta Vigo and Espanyol continued their improvement under coach Javier Aguirre with a 3-2 victory over Levante.

For Valentine's Day, Cupid ditches arrows, opts for e-cards

Admit it. You've always wanted to love like John Travolta.

(Credit:

Romance isn't dead.

It's merely been reduced to the level of a friend request, a poke, and a privacy control.

Often in that order.

How else can one interpret the staggeringly predictable research -- performed on behalf of SOASTA, the oddly named company that performs cloud and mobile testing -- that suggests more than a third of American human beings will send an e-card for Valentine's Day?

It's true that some e-cards can be amusing, uplifting, even offering an instant surprise on an otherwise moribund day. But can they truly incite a loving feeling on America's most commercially amorous day of the year?

You will be stunned into loving only yourself for the rest of your days when I tell you that -- of the 2,474 American adults surveyed -- men seem a little keener on Valentine e-cards than women.

Indeed, this research offered that 47 percent of men between the ages of 35 and 44 indicated that the love of their life deserved merely a few clicks and a canned expression of love.

Next in enthusiasm were men aged 18-34, 41 percent of whom will let their fingers do the loving.

But let's not besmirch these men any more than they deserve. 41 percent of women aged 18-34 also claimed that e-cards were their chosen method to stroke their chosen one.

Clearly, convenience is at the heart of this e-card enthusiasm, just as it is at the heart of modern romance.

Respondents were radiant at the idea that e-cards are free. 35 percent beamed at the fact that they offer the possibility of animation. And a deeply serious 34 percent felt the need to point out they were environmentally friendly.

A surprisingly paltry 6 percent admitted that they loved e-cards because you could happily include NSFW content.

More Technically Incorrect

Because ours is an acquisitive society, those who send these free, convenient things to express their temporarily undying love actually expect something in return.

A kiss is expected by 8 percent. A fulsome 10 percent expect sex. They must be among those who believe you can get something for nothing.

There will be those who reach for their Latin and mutter: "Sic transit tragoedia mundi." (Oh, look it up, e-carders.)

But when a whole new personal version of oneself is being created and spun online, who can be surprised that other expressions of love might seem not merely passe but also downright unexpressive?

E-cards surely allow you a far greater breadth than paper cards or balloons to display precisely what you really feel about the most important person in your life.

Which, in the case of 3 percent of the respondents in this moving survey, is "the hot receptionist at work."

Pictures We Love: Best of January

Photograph by Dieu Nalio Chery, AP

The magnitude 7 earthquake that struck near Port au Prince, Haiti, in January 2010 so devastated the country that recovery efforts are still ongoing.

Professional dancer Georges Exantus, one of the many casualties of that day, was trapped in his flattened apartment for three days, according to news reports. After friends dug him out, doctors amputated his right leg below the knee. With the help of a prosthetic leg, Exantus is able to dance again. (Read about his comeback.)

Why We Love It

"This is an intimate photo, taken in the subject's most personal space as he lies asleep and vulnerable, perhaps unaware of the photographer. The dancer's prosthetic leg lies in the foreground as an unavoidable reminder of the hardships he faced in the 2010 earthquake. This image makes me want to hear more of Georges' story."—Ben Fitch, associate photo editor

"This image uses aesthetics and the beauty of suggestion to tell a story. We are not given all the details in the image, but it is enough to make us question and wonder."—Janna Dotschkal, associate photo editor

Body of Missing Mom Reportedly Found in Turkey

The body of an American woman who went missing while on a solo trip to Turkey has been pulled from a bay in Istanbul, and nine people have been held for questioning, according to local media.

Sarai Sierra, 33, was last heard from on Jan. 21, the day she was due to board a flight home to New York City.

The state-run Andolu Agency reported that residents found a woman's body today near the ruins of some ancient city walls in a low-income district, and police identified the body as Sierra.

Rep. Michael Grimm, R-NY, who with his staff had been assisting the Sierra family in the search, said he was "deeply saddened" to hear the news of her death.

"I urge Turkish officials to move quickly to identify whomever is responsible for her tragic death and ensure that any guilty parties are punished to the fullest extent of the law," he said in a statement.

The New York City mother, who has two young boys, traveled to Turkey alone on Jan. 7 after a friend had to cancel. Sierra, who is an avid photographer with a popular Instagram stream, planned to document her dream vacation with her camera.

"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul last Sunday to aid in the search.

Steven Sierra has been in the country, meeting with U.S. officials and local authorities, as they searched for his wife.

On Friday, Turkish authorities detained a man who had spoken with Sierra online before her disappearance. The identity of the man and the details of his arrest were not disclosed, The Associated Press reported.

The family said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.

She took two side trips, to Amsterdam and Munich, before returning to Turkey, but kept in contact with her family the entire time, a family friend told ABC News.

Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey.

Astrophile: A scorched world with snow black and smoky

Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse

Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b

There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.

HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.

HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.

Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.

Stuck on the surface

Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.

Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.

Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.

Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphere.

David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."

Hot, black snow – now that would be something to wake up to.

Israeli raid hit Syrian missiles, buildings: US official

WASHINGTON: An Israeli air raid in Syria this week struck surface-to-air missiles and a nearby military complex on the outskirts of Damascus, as Israel feared the weapons would be transferred to Hezbollah, a US official said Friday.

Earlier reports had suggested Israeli warplanes may have targeted two separate locations in Wednesday's raid in Syria: a military site outside of the capital and a weapons convoy near the Lebanese border.

But the US official said the strike was confined to one location.

"It was in the suburbs of Damascus," the official, who spoke on condition of anonymity, told AFP.

"There were surface-to-air missiles on vehicles" that were targeted by the Israel aircraft, he said, adding that they were believed to be Russian-made SA-17 anti-aircraft missiles.

The planes also bombed an adjacent military complex of buildings suspected of housing chemical agents, the official said.

The Israelis suspected the weapons would be transferred to Lebanon's Shiite Hezbollah group, he said.

The Syrian regime has accused Israel of launching a dawn strike Wednesday on a military research centre in Jamraya, near Damascus, and threatened to retaliate.

But the Israeli government has maintained a public silence on the strike.

Israel has repeatedly expressed concern that Syria's stockpile of chemical weapons could fall into the hands of Lebanon's Shiite Hezbollah group, which is an ally of the Damascus regime, or other militant organisations.

Rarified Retina MacBook Pros get priced closer to earth

13.3- and 15.4-inch Retina MacBook Pros

Apple)

MacBook Pros equipped with a Retina display are not exactly priced to move. Best Buy and Amazon are trying to change that.

Best Buy, for example, is now selling the 128GB version (model MC975LL/A) of the 13.3-inch
MacBook Pro Retina for $1,549.99, $150 off the regular $1,699.99 price.

Need 256GB of solid-state storage with that gorgeous Retina screen? That model (MD213LL/A) is now $1,799.99, $200 off the regular price of $1,999.99.

The pricier 15.4-inch models with 256GB and 512GB solid-state drives (MC975LL/A and MC976LL/A, respectively), also got $200 lopped off their regular prices.

Amazon is going even lower, pricing the 128GB 13.3-inch model at $1,515.59, for example.

The online retailer is offering identical discounts to Best Buy on the 15.4-inch models.

These sales may be short-lived (the Best Buy sale is for two days only) but expect more of this kind of discounting from retailers in the future. Apple's Mac sales sank last quarter to 4.1 million compared to 5.2 million in the same quarter last year.

Some of that is because consumers are opting for the cheaper
iPad, but the Retina MacBook Pros may be a factor too. When Apple sells configurations that push the least expensive Retina model to $1,700 ($1,699) at the regular price, that's not going to win over a lot of buyers.

Best Buy sale: For two days, the 13.3-inch Retina MacBook Pro now starts at $1,549.99.

A micrograph, or microphotograph, of a sea urchin's crystalline tooth won first place and people's choice for photography in the 2012 International Science and Engineering Visualization Challenge.

Colors applied with Photoshop reveal the interlocking crystals that form the choppers of Arbacia punctulata. The biomineral crystals, captured by biophysicists from the University of Wisconsin, Madison, grow and intertwine to reinforce and sharpen a sea urchin's teeth. Made of calcite, which is also found in limestone and seashells, the crystals are tough enough to grind holes in rocks to create shelters.

"These winners continue to amaze me every year," said Monica M. Bradford, executive editor of the journal Science, in a statement. "The visuals are not only novel and captivating, but they also draw you into the complex field of science in a simple and understandable way."

Sponsored by Science and the National Science Foundation (NSF), the international competition honors recipients who use visual media to promote understanding of scientific research. Judging criteria included visual impact, effective communication, freshness, and originality. (See some of the 2011 winners.)

Arias Trial Puts Mormon Sex Rules in Spotlight

The murder trial of Jodi Arias has been filled with salacious details of phone sex, graphic text messages, and an erotic sexual relationship between her and her devout Mormon ex-boyfriend, Travis Alexander.

Arias, 32, converted to Mormonism when she began to date Alexander, then 29, in 2006. Though they were both outwardly devout, they immediately developed a sexual relationship.

The trial has cast a spotlight on the tight-knit Mormon community in Mesa, Ariz., and its strict social mores, including a ban on premarital sex. According to Patrick Mason, a professor of religion who specializes in Mormon studies at Claremont Graduate University in California, the trial shows the difficulty Mormons face in coping wiith the church's demand for chastity.

"The LDS church puts a really high priority on complete chastity," Mason said. "They define that as no sexual relations of any kind outside of marriage between a man and a woman, no premarital sex and no extramarital sex either, and there's actually a lot of time and attention paid to this."

Arias is on trial for murdering Alexander, whom she dated for a year and then continued to have sex with for a year after that. Prosecutors allege she killed him in a fit of jealousy in June 2008, after taking graphic sexual photos with him and having sex earlier in the day.

Arias claims she shot and stabbed Alexander in self defense, and her attorneys have focused on Alexander's secret sex life as proof that he was a "sexual deviant" who was abusive and controlling toward Arias.They claim Alexander, who was considered a church elder, kept Arias his "dirty little secret" because sex outside of marriage was against church rules.

See Jodi Arias Trial Videos
More than anything, Mason said, this case shows the shockwaves sent through Arizona's Mormon community when those values were breached so flagrantly with a violent killing and the web of lies surrounding it. "Mesa is one of those concentrated areas of historic Mormon settlement."

"Were you shocked to learn (Alexander) was not a virgin?" defense attorney Jennifer Willmott asked Lisa Daidone, who dated Alexander after he broke up with Arias. Alexander and Arias continued to sleep together while he dated Daidone.

"Yes," Daidone said on the stand Wednesday. "I believed he was a virgin."

"Was Mr. Alexander living in accordance with his Mormon principles?" defense attorney Kirk Nurmi asked another witness, Daniel Freeman, a Mormon friend of Alexander's in Arizona.

"Yes," Freeman said on the stand Thursday.

"Was there any reason to believe Mr. Alexander was not living up to his Mormon principles as a church elder?"

"No," Freeman said.

Freeman said that Alexander never told him or other church members that he had a sexual relationship with Arias. In fact, Freeman's sister, Desiree Freeman, testified that Alexander made it known he was a virgin when in social settings, and "he joked about it."

The stakes are high for Mormons who choose to have sex, Mason said. They can face excommunication or a tarnished reputation among their closest friends and family members.

"In Mormonism, if you're not married, your social capital is largely defined by preserving your virginity. If it is known that you've had sex before marriage, even if people try to be compassionate and not judgmental, there is no doubt that in Mormon communities and the eyes of other Mormons... it lessens your social standing."

The conflict between Alexander's outer appearances and his secret sexual trysts with Arias is key to the defense's strategy of painting him as an abusive lover. But the testimony has also shown, conversely, how sexually conservative and pure many young Mormons in America are.

Swarm-mongering: Brainless blobs flock together

Birds of a feather flock together and now so do brainless, inanimate blobs. Made of microscopic particles, the artificial swarms could shed light on the mysterious mechanisms behind the natural swarming seen in fish and birds. They might also lead to materials with novel properties like self-healing.

Animals such as birds, fish and even humans that move together in swarms have individual intelligence, but Jérémie Palacci of New York University and colleagues wondered whether inanimate objects could also swarm. "From a physicist's point of view, if many different systems behave in the same way there must be an underlying physical rule," he says.

To explore this idea, the team created microscopic plastic spheres, each one with a cubic patch of haematite, an iron oxide, on its surface. When submerged in hydrogen peroxide, the spheres spread out in a disordered fashion. The team then shone blue light on the particles, causing the haematite cubes to catalyse the breakdown of any nearby hydrogen peroxide into water and oxygen. As hydrogen peroxide concentration dropped temporarily in these regions due to the reaction, osmotic forces cause more hydrogen peroxide to flow into them, and that in turn buffets the spheres. The whole process then repeats.

Self-healing swarm

When two spheres come close enough to each other, the balance of chemical forces shifts so that the two spheres are attracted. If there are enough spheres in the same place they will cluster together to form shapes of symmetrically arranged particles, which the team call crystals (see video, above). These crystals continue to be buffeted by the movement caused by the breakdown of hydrogen peroxide – but now they move together as one object, replicating a life-like swarm. Switch off the light, however, and the reaction stops, causing the crystal to lose the forces that hold it together, and the particle distribution becomes disordered once again.

"This system shows that even though the particles have no social interaction or intelligence, you can exhibit collective behaviour with no biology involved," says Palacci. Since the haematite is magnetic, it is even possible to steer the crystals in one direction by applying a magnetic field. Such control might be useful if the artificial swarms are to be harnessed for applications.

As the particles automatically fill any gaps that form in the crystal, again thanks to the chemical dynamics of the system, they could be used to create a self-assembling, self-healing material. The work is published in the journal Science today.

Schooled by fish

Iain Couzin of Princeton University says these kinds of systems are very useful for studying biological collective behaviour because researchers have complete control over their interactions – unlike natural systems.

His team has its own swarming experiment published in the same issue of Science, based on schools of fish that prefer to stay in shade. Their paper shows that shining a light on some of the fish in the school causes them to speed up, to get away from the light. But as a result, non-illuminated fish also speed up, even though, if acting purely as individuals, they would have had no reason to do so. "We show just by using simple interactions that schools can have a sense of responsiveness to the environment that individuals do not have," he says.

Couzin sees no reason why such behaviour should be limited to natural systems. "In future it may be possible to create systems of particles that can make collective decisions – something we often think of as only possible in biological systems," he says.

Candidates to head WTO clear hurdle

GENEVA: The last of a record nine candidates to lead the World Trade Organization finished defending their candidacies on Thursday, but the real campaign is only just getting started.

"This is a procedure that is all but unique in the world -- a selection rather than an election that takes several months to complete," a source close to the process told AFP.

The candidates -- six men and three women mainly from developing nations -- are all considered confirmed global trade specialists and are vying to replace Frenchman Pascal Lamy, who finishes his second four-year term in August.

This past week, they have all gone before the WTO's general council for gruelling questioning about their merits and visions for the organisation, which oversees global trade practices and is trying to reduce tariffs that hobble exchanges.

The interviews took place behind closed doors, but in subsequent news conferences all the candidates stressed the urgency in addressing the WTO's main challenge: jump starting the stalled Doha Round of trade talks that was launched in 2001.

"The reality is that the round at this point in time is paralysing the system, and we have to solve it," insisted Brazil's envoy to the WTO Roberto Azevedo, who was one of three candidates from Latin America -- a heavily-tipped region to land the organisation's top job -- and the last of the nine to face the fire.

South Korean Trade Minister Taeho Bark, the only other candidate who spoke Thursday, agreed, insisting that "there's a need to rebuild trust."

On Wednesday, New Zealand Trade Minister Tim Groser, the only candidate from an advanced economy and therefore considered a longshot since the UN's trade body appears set on picking someone from a developing nation, stressed that the WTO was facing a "problem of relevance."

Mexican economist and former minister Herminio Blanco Mendoza also cautioned Wednesday that the WTO risked "losing relevance" if the next Doha-round talks in Bali at the end of the year failed.

Former Jordanian trade minister Ahmad Thougan Hindawi, the only Middle Eastern candidate, also spoke Wednesday of a need of "a fresh outside look" to get the process moving.

"After 12 years of stalled negotiations, to think of modernising," agreed high-level United Nations executive Amina Mohamed of Kenya, one of two candidates from Africa -- a region also thought likely to provide the organisation's next leader.

While insisting that her candidacy was purely based on merit, Mohamed said that "it would send a very, very powerful signal ... if this organisation decided that a woman, preferably an African woman, should take over at the helm of the WTO."

Indonesia's current tourism minister and former trade minister Mari Elka Pangestu, who might have less of a chance given that Lamy's predecessor Supachai Panitchpakdi comes from neighbouring Thailand, also told media on the first day of interviews Tuesday that the WTO would be well-served by having a woman at the top.

The third woman who has thrown her hat in the ring, Costa Rica's Foreign Trade Minister Anabel Gonzalez, meanwhile said she was a "cautious optimist" that the WTO would get the Doha round on track.

Ghana's former trade minister Alan John Kwadwo Kyerematen, who was the first to make his case on Tuesday, also spoke of the need to "revitalise an extremely important organisation."

As the interview process wrapped up Thursday, the candidates were preparing three months of world travel to convince the 158 WTO member states of their merits.

The final selection will be made by a "troika" composed of the yet-to-be-picked presidents of the WTO's general council, its Dispute Settlement Body and its Trade Policy Review Board.

Once the three leaders have been chosen, something that must happen by the end of February, the troika will ask each member state to provide their two favourite candidates, as well as the one they are most opposed to.

Based on the responses they receive, the three WTO leaders will gradually begin dropping candidates, with the ones who stand little chance of being selected expected to withdraw of their own volition.

The decision must be made no later than May 31, and the nominee is to take over at the WTO on September 1.

Smart LED desk lamp is sensitive to your moods

It's more than just a lamp.

Satechi)

The day of the single-purpose gadget is rapidly fading. You can't just have a phone that you use to talk to other people. It has to do 50 other things. You can't just have a desk lamp that lights up your desk. You have to have one that charges your phone and gives you mood lighting, too.

The Satechi Smart LED Desk Lamp tries to fit as much functionality in as it can. It charges smartphones and has a built-in timer to power it off. It's also very touchy-feely. It's controlled through a touch panel and has different lighting modes to fit your mood.

The lamp can be dimmed in increments, or you can choose one of four pre-sets. Reading mode features a mid-range color temperature to be easy on your eyes. Study mode has high-range color temperature, supposedly to increase concentration. Relaxation mode brings low-range color temperature to encourage you to kick back. Bedtime mode has a soft light for people who like to sleep at their desks.

Phone charging functions aren't new to desk lamps. Konica Minolta came out with wireless charging lamp late last year. The Satechi lamp doesn't do wireless, but at $100, it's $200 cheaper than the Konica Minolta. If you're the kind of person who's not satisfied with single-function devices, then the Satechi lamp could be worth a look.

Charge your phone while relaxing with your mood lighting.

14 Pygmy Elephants Die Mysteriously in Borneo

Fourteen endangered Borneo pygmy elephants have recently been found dead in a Malaysian forest, presenting a mystery for wildlife officials and conservationists.

The recent deaths highlight the vulnerable status of the species, which now numbers about 1,500 animals. Scientists don't know how many pygmy elephants previously existed on the island, although it's likely the population wasn't much higher than it is today, said Barney Long, head of Asian species conservation at WWF-US.

This week Malaysian authorities discovered a group of elephant carcasses close together in the Gunung Rara Forest Reserve, located in the northeastern corner of Borneo (map), a Southeast Asian island shared by Indonesia, Malaysia, and Brunei.

"We don't know officially yet how they died, but what we do know is this is an area of forest that is being cleared for plantations, and it's very common that when the forest is cleared, conflict between humans and elephants spikes," said Long.

For instance, in agricultural areas in neighboring Sumatra, people have put out poisoned fruit for elephants to eat, causing a whole herd to drop dead in one area. The poison is usually whatever is locally available, such as rodenticide, he said.

"The presumption here is that [the recent deaths are] similar to that. Obviously that is complete guesswork until we have results of the autopsies," Long said.

The Malaysian government is performing autopsies on the dead elephants, although it's unknown when they will release the results, he added.

Cute Elephant Dwindling in Number

Pygmy elephants were isolated about 300,000 years ago from their relatives on mainland Asia and Sumatra and evolved their small size to adapt to forest living.

With their baby faces, oversize ears, and plump bellies, "Walt Disney himself couldn't have crafted a cuter elephant," according to WWF's website. (Visit National Geographic's elephant hub.)

But the population of this charismatic mini-elephant is dwindling in number as large tracts of Borneo's forests are cleared to make way for palm oil plantations, restricting the animals to increasingly smaller areas and forcing them into closer contact with people. (Get more elephant news on the National Geographic blog A Voice For Elephants.)

For example, the mammals need about 115 square miles (300 square kilometers) in which to find enough food, water, and minerals, according to WWF's studies of elephants fitted with radio collars.

"When you chop down part of their habitat, they're still going back there looking for resources that used to be there," Long said.

And if that happens to be a plantation, that's when run-ins with people occur.

Pygmy Elephants Need Protection

Whatever caused the recent deaths, the incident has prompted WWF to call on the Malaysian government to better protect pygmy elephants. (Also see "'Extinct' Pygmy Elephants Found Living on Borneo.")

For one, the species needs to be listed as "totally protected" by law in Malaysia, which has been recommended by scientists but not yet enacted by the government, WWF-Malaysia executive director Dionysius S.K. Sharma said in a statement.

Though the animals are already protected from hunting, the huge swaths of habitat they rely on also need to be set aside from logging.

What's more, the local wildlife department needs to invest more resources in patrolling the area for illegal activities, Sharma said.

"Frequent and large-scale patrolling is critical to avoid such conflict from happening again," he said.

Though the killings won't be disastrous for the population overall, noted WWF-US's Long, what it is showing "is a huge pressure on elephants."

"If this is a case of poisoning, [it shows] how easy it is for one individual to wipe out a significant number [of elephants]."

Arias' Ex-Boyfriend Kept Affair Secret

Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.

The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."

Arias' attorneys introduced as evidence photos that Alexadner took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.

Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.

Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.

"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.

"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.

Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.

Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."

"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.

Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.

In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.

"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"

"She would not be ready to be baptized in that case," Freeman said.

"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.

"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."

Freeman said that Alexander never confessed to having a sexual relationship with Arias.

Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.

The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

Departing Kerry warns senators of crippling gridlock

WASHINGTON: US Senator John Kerry offered some tough love Wednesday to the colleagues he leaves behind to become secretary of state: end the fierce partisanship or risk the nation's reputation as a beacon of democracy.

Kerry, whose confirmation as President Barack Obama's choice to replace Hillary Clinton as chief US diplomat sailed through the Senate a day earlier, said lawmakers needed to end the chamber's "reputation as a sanctuary of gridlock" and get down to legislating through compromise and consensus.

"If democracy deadlocks here, we raise doubts about democracy everywhere," Kerry, who at times turned emotional in his farewell speech on the Senate floor, told Democrats and a smattering of Republicans.

"If we use the time to posture politically in Washington, we weaken our position across the world."

Lawmakers in the House and Senate have engaged in bruising partisan debate and voting in recent months, notably concluding the 112th Congress a month ago by waiting until the final hour to reach only a partial deal to avoid a series of fiscal crises including tax hikes and spending cuts.

Kerry, a 28-year veteran of the chamber, appeared to be offering his words of advice in part as a plea for cooperation as he takes on the task of leading US foreign policy.

"As I prepare to represent our nation in capitals around the world, I am more than conscious that my credibility as a diplomat and ours as a country is determined to a great degree by what happens right here in our capital city," Kerry said.

"The antidote to the current narrative of American decline" being put forward in rival nations like China and Iran, he said, "is to demonstrate that we can get our economic house in order -- because we can be no stronger abroad than we are here at home. It's that simple."

Despite the harsh assessment, Kerry spoke warmly of his colleagues across the aisle, particularly Republican John McCain, who, like Kerry, fought in the Vietnam War but found "common ground" with him on several issues.

And the future secretary of state could not help but make light of how he, like McCain, came up short in his presidential ambitions.

"Eight years ago I admit that I had a very different plan... to leave the Senate, but 61 million Americans voted that they wanted me to stay here with you," he said to laughter in the chamber.

Kerry choked up several times during his 45-minute speech, including when he spoke of President John F. Kennedy and brother Ted Kennedy, from whom Kerry inherited his mahogany desk in the Senate when the younger Kennedy died in 2009.

Massachusetts Governor Deval Patrick on Wednesday appointed his former chief of staff, William "Mo" Cowan, to temporarily fill Kerry's Senate seat until a special election is held on June 25.

In picking a relative political unknown, Patrick passed over other potential appointees including long-serving congressman Barney Frank, who retired early this month, and Vicki Kennedy, the widow of former US senator Ted Kennedy.

The departure of Kerry, whose confirmation breezed through the Senate on Tuesday, sets off a scramble for a seat in a liberal state where Democrat Elizabeth Warren defeated incumbent Senate Republican Scott Brown in November.

6 Bizarre Animal Smuggling Busts

Officers in Bangkok's Suvarnabhumi International Airport recently discovered 11 live otters in a piece of unclaimed luggage left at the oversized baggage area.

The six smooth-coated otters (Lutrogale perspicillata)—Southeast Asia's largest otter—and five oriental small-clawed otters (Aonyx cinerea), the world's smallest otters at less than 11 pounds (five kilograms), are under threat in Southeast Asia.

Demand for their pelts and organs for clothing, food, and medicine—in addition to habitat destruction and environmental pollution—have diminished both populations. (Read an exposé of the world's most notorious wildlife dealer, from National Geographic magazine.)

But otters aren't the only victims of the illicit wildlife trade. Stuffed into carry-ons, packed into suitcases, and bundled into crates, traffickers have tried to smuggle all kinds of wild animals through airports.

"The U.S. seizes over $10 million worth of illegal wildlife each year, but this only scratches the surface," said Edward Grace, deputy chief of the U.S. Fish and Wildlife Service Office of Law Enforcement. "[On] any given day, someone, somewhere in the world, is poaching or smuggling wildlife."

Here are six other kinds of wild animals that people have tried to sneak past customs.

Birds: To smuggle more than a dozen hummingbirds (family Trochilidae) past customs, a Dutchman at an airport in French Guiana (map) wrapped each bird in cloth and hid them in a pouch sewn into the waist of his pants in 2011. He even taped the tiny bundles to keep the birds from escaping. His fidgeting led French customs officers to discover the birds.

Monkeys: In 2002, a Los Angeles man returning from Bangkok (map) owned up to hiding two endangered pygmy monkeys, called slow lorises (Nycticebus spp.), in his underwear. His confession came after officials opened up his luggage and a bird of paradise (Paradisaeidae spp.) flew out. He was also traveling with 50 rare orchids.

Crocodiles: A crocodile smuggled on board a domestic flight in 2010 from the Democratic Republic of the Congo (map) was blamed for a plane crash that killed 20 of 21 passengers. The reptile escaped from a duffel bag in the cabin and panicked the passengers and crew, according to news reports from the sole human survivor. The animal survived the crash but was later killed with a machete.

Snakes and Other Reptiles: An exotic animal salesman attempting to transport 247 reptiles and spiders to Spain was caught by x-ray technicians in Argentina in 2011. The exotic and endangered species included boa constrictors, poisonous pit vipers, and spiders. They were packed inside plastic containers, bags, and socks.

Tropical Fish: In 2005, customs officials in Melbourne, Australia (map) stopped a woman who had arrived from Singapore after hearing mysterious "flipping" noises coming from around her waist. They found an apron under her skirt designed with pockets holding 15 plastic bags filled with water and 51 tropical fish.

Big Cats: In 2011, a United Arab Emirates man at Bangkok's Suvarnabhumi International Airport packed two leopards and two panthers into his luggage—as well as an Asiatic black bear and two macaque monkeys. Every animal was under two months old, and had been drugged for the journey. Some of them were stored in flat cages, while others were placed in canisters with air holes. (See pictures of other animals smuggled through Bangkok International Airport.)

Arias Trial Shocked by Slashed Throat Photo

The courtroom at the Jodi Arias murder trial was shocked -- and Arias began sobbing -- when the prosecutor stunned them by suddenly flashing a photograph of Arias' ex-boyfriend Travis Alexander with his throat slashed open.

Alexander's sisters and friends burst into tears and one ran out of the courtroom when prosecutor Juan Martinez held up the grisly picture of Alexander with his throat slashed and bloodied.

Arias, who is on trial for allegedly murdering Alexander, sobbed uncontrollably at the sight of the photo. She is accused of stabbing Alexander 27 times, slashing his throat, and shooting him twice in the head in a bout of jealousy. She could face the death penalty if convicted.

In the moments before the incident, Martinez was questioning Lisa Daidone, who dated Alexander in 2007 after Alexander's break up with Arias but while he and Arias continued to sleep together. The defense had gone painstakingly through an angry email Daidone had sent Alexander to break up with him, after she found out he was cheating on her with Arias.

"Do you think that even with everything they claimed he put you through, do you think it is appropriate to take a knife and slash somebody's throat?" Martinez yelled.

"Is this what a normal relationship looks like to you?" Martinez shouted as he held up the picture amid shouts of "objection" from the defense and gasps from onlookers.

Judge Sherry Stephens called for a recess, and when the court returned the judge warned the audience to keep their reactions to testimony silent.

The outburst came at the end of an intense line of questioning from Martinez as he asked Daidone to explain that Alexander treated her well during their relationship, attempting to disprove the defense's accusations that Alexander was a sex-obsessed, aggressive cheater.

Daidone had testified under questioning by Arias' lawyers that she broke off her relationship with Alexander several times partly out of her suspicions that he was cheating on her, although he had asked her to marry him.

As Mormons they refrained from sex before marriage and she was surprised to find out after Alexander's death that he was not a virgin. Another witness, Desiree Freeman, told the court that Alexander claimed to be a virgin. "He made jokes about it" and seemed proud of the fact, Freeman testified.

The defense cited Daidone's breakup email listing her complaints about Alexander in their effort to portray Alexander as an aggressive philanderer.

"Did you tell him that you felt he wanted you just for your body, that kissing didn't mean anything to him and was just a way for him to let out sexual tension? And that it made you feel used and dirty?" defense attorney Jennifer Willmott asked Daidone.

Daidone said yes, and that she "had felt that way then."

But the prosecutor grilled Daidone about that email, drawing a picture of a more reserved and sexually restrained Alexander.

"You were asked about that email," Martinez said, "and one of the things you talked about, isn't it true that Mr. Alexander wouldn't kiss you at the start of the relationship? You were the person who initiated contact? He was the person holding it up, right? He was holding up your religious beliefs?" Martinez asked.

Daidone agreed.

"He was doing everything he could to conform to what you wanted, wasn't he? Not other way around," Martinez said.

Daidone said that when she sent the angry email to Alexander, criticizing him for thinking about sex and talking about sex, that she was "inexperienced" and "immature," and she later came to regret saying those things to him.

Daidone said that Alexander always kept in close contact with Arias, texting and calling her often. She was suspicious that he was cheating on her, but did not know they were involved sexually.

Erectile dysfunction signals heart troubles: study

WASHINGTON: Erectile dysfunction might signal more than a need for the little purple pill, researchers said Tuesday in a study showing a link with heart disease and early death.

The Australian study -- the world's largest investigating links between erection problems and heart disease -- suggested erection problems could act as a warning sign of more serious health issues.

"The risks of future heart disease and premature death increased steadily with severity of erectile dysfunction," whether or not there was a history of cardiovascular disease, study director Emily Banks said.

Previous studies had found ties between severe erection problems and heart attacks and strokes, but this study was the first to also include mild and moderately severe erection problems.

"These results tell us that every man who is suffering from any degree of erectile dysfunction should be seeking medical assistance as early as possible and also insisting on a heart health check by their GP at the same time," said Rob Grenfell, Cardiovascular Health director at Australia's Heart Foundation.

The study, published this week in the "PLOS Medicine" journal, followed 95,000 men aged 45 and older for two to three years.

The men responded to a survey on their health and lifestyle, and the authors also studied any records of hospital stays or deaths in the group.

Over the study period, there were 7,855 hospitalisations for cardiovascular disease and 2,304 deaths.

Banks said that the study indicated that erection problems seemed to a symptom of heart problems.

"Rather than causing heart disease, erectile dysfunction is more likely to be a symptom or signal of underlying 'silent' heart disease and could in future become a useful marker to help doctors predict the risk of a cardiovascular problem.

"This is a sensitive topic but men shouldn't suffer in silence; there are many effective treatments, both for erectile dysfunction and for cardiovascular disease," she emphasized.

Erection problems are very common. About one in five men over 40 report moderate or severe erectile dysfunction.

Smaller Apple TV box hinted at in FCC filing

A new regulatory filing suggests Apple is readying a fourth-generation Apple TV set, one that looks a whole lot like the last two models, but with one minor difference.

That difference is size. The new version, which was spotted by Endgadget in a filing with the Federal Communications Commission (FCC) today, is 93.78mm around versus the current model's 98mm. It also carries the model number A1469, which differs from the current model's A1427 designation.

The filing comes on the heels of a reference to an unreleased
Apple TV model inside of
iOS 6.1, which Apple released to the public yesterday after months of testing. Like the iPhone,
iPad and iPod touch, the Apple TV also runs iOS, though differs in various ways -- notably a lack of touch interface, and the capability to install and use third-party applications.

Apple updated the Apple TV's hardware last March with a third-generation model that added 1080p playback. Since then Apple has put out a handful of interim software updates that added new features, including compatibility with iTunes Match and more recently Bluetooth keyboards. The company is still expected to roll out a full-fledged TV set, possibly as soon as this fall, putting any interim hardware releases under closer scrutiny.

Timbuktu’s vulnerable manuscripts are city’s "gold"

French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."

Jodi Arias Borrowed Gas Cans Before Killing Ex

Accused murderer Jodi Arias borrowed two five-gallon gas cans from a former boyfriend the day before she drove to Arizona to kill another ex, Travis Alexander, according to testimony in Arias' murder trial today.

In cross examination, prosecutors also forced Arias' former live-in boyfriend Darryl Brewer to describe his sex life with Arias as "pretty aggressive."

Brewer, 52, dated Arias for four years and shared a home with her in California for two years. He told the court today that Arias called him in May 2008, asking to borrow gas cans, but would not explain why. She called him again at least two more times, and arrived at his house on June 2008, to borrow the cans.

On the day she picked up the gas cans she told Brewer that she was going to visit friends in California and Arizona.

Prosecutors argue that Arias then drove to Mesa, Ariz., where she allegedly had sex with Alexander, took nude photos of him, and then stabbed him 27 times, slashed his throat, and shot him twice in the head. She is charged with murder and could face the death penalty if convicted.

Arias, who claims she killed Alexander in self defense, had approached prosecutors two years ago offering to plea to a second degree murder charge, which could carry a 25 year term, but the state rejected the offer, Nancy Grace reported on Good Morning America today.

Brewer said that Arias never returned the gas cans. The pair had been broken up two years earlier and they had only spoken "sporadically," he said.

Prosecutors also showed receipts from Arias' trip from her California home to Alexander's home in Mesa, showing that she purchased a 10 gallons of gas at one gas station the night before she drove to Arizona, and then another 10 gallons from a different gas station 10 minutes later. Prosecutors are expected to argue she brought the gas with her to fill up her car secretly on the way to Alexander's home, showing premeditation for the murder.

Arias' attorneys called Brewer as one of their first witnesses as they began mounting their case that Arias killed Alexander in self defense, arguing that Alexander was controlling and abusive toward Arias.

They asked Brewer to explain how he and Arias had been in a stable relationship for four years, from 2002 to 2006, and had bought a home together before Arias met Alexander at a business conference and began to change.

"I saw a lot of changes in Jodi. She became a different person than I had known previously," Brewer said, describing how Arias' behavior changed in May 2006 when she joined a company called Pre-Paid Legal. There, she met Alexander and began seeing him. She continued to live with Brewer.

"She had continued to pay the mortgage, but she was not paying other household bills, she began getting into debt or financial trouble," Brewer said. "For me it seemed she was not as rational or logical."

Arias also converted to Mormonism while living with Brewer, telling him that he could no longer curse and she would no longer have sex with him because she was saving herself for marriage.

The pair had previously had an "enthusiastic" and "aggressive" sex life, Brewer admitted to prosecutors. They had engaged in anal sex, Arias had taken nude photos of Brewer, and Arias had purchased breast implants in 2006, he testified.

Brewer said that after Arias began to change, he made arrangements to move closer to his son from his first marriage, and he and Arias broke up.

They kept in touch with occasional phone calls until Arias asked to borrow the gas cans in June 2008, and then called him a week after borrowing the cans to say that her friend had been killed.

Martinez, reading notes from an interview Brewer gave to authorities during the investigation into Alexander's death, asked if Arias had ever mentioned needing an "alibi." Brewer said he did not recall any conversation about alibis.

"After this date of June 4, 2008," Martinez asked, "you received a call from Jodi Arias, and she was very agitated?"

"She was sad," Brewer said.

"Did she tell you that her friend had been killed and she did not have an alibi?"

"I don't remember that," Brewer said.

Arias was arrested a month after Alexander was found dead, in July 2008.

Iran launches monkey into space

Lisa Grossman, physical sciences reporter

Last summer, the Iranian Space Agency announced their plan to send a monkey into space - and now they've apparently done it.

According to Iranian state-run television, a press release on the space agency's website, and photos of the event, Iran sent a live rhesus monkey into sub-orbital space aboard a small rocket called Pishgam, or Pioneer. There's even a video posted on YouTube that appears to be of the launch (though New Scientist could not confirm its authenticity).

The report has not been confirmed independently, however, and the US air force's North American Aerospace Defense Command (NORAD) has not reported seeing any missile launches from Iran.

But independent observers say the launch looks legitimate.

"Really, I see no reason not to take their word for it," says Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who also keeps a log of space launches. He says he's convinced by the photos and discussions he's had with several knowledgeable source in online forums.

In photos released on the Iranian Space Agency's website, the rocket looks like the same kind the agency has launched before, but with a larger nose cone designed to fit a small chamber that can support life. Images also showed a live rhesus monkey strapped to a small seat.

The reports say the rocket went straight up 120 kilometres, which McDowell says qualifies as outer space, but not high enough to reach orbit, and came back down with a parachute.

It's unclear exactly when the launch took place. The press release says that the launch happened on the birthday of Mohammed the Prophet, which is celebrated by Shiites on 29 January, but was celebrated last week elsewhere in the world.

Some countries worry that Iranian rockets capable of carrying animals or people could also carry weapons. Iran has denied any military intention.

"This is not a scary thing because this is not a big new rocket that could hit America or anything like that," McDowell says. "There's nothing military to this. It's purely for propaganda. Nevertheless, it advances their science and their technology by being able to do it."

Iran says the launch is a first step towards sending humans into space, which they intend to do in the next 5 to 8 years. To do that, McDowell says, they'll need to build a larger rocket. The country currently has a vehicle called Safir that has successfully put satellites in orbit, and is developing a more powerful launcher called Simorgh.

The next step will probably be to either launch Safir to carry a human to sub-orbital space, or an unmanned Simorgh flight into orbit to make sure mission controllers can return it to the ground safely.

"They don't want to repeat what the Soviets did" in 1957, McDowell says, "which is put a living being in orbit before you figure out how to get it back."

Golf: Tiger wins Torrey Pines title for 75th career crown

LA JOLLA: World No. 2 Tiger Woods captured his 75th career title on Monday, winning the US PGA Farmers Insurance Open by four strokes for his record-setting eighth career triumph at Torrey Pines.

Despite struggling in windy conditions Monday over the final 11 holes, Woods showed flashes of the form that has brought him 14 major titles as he chases the all-time record of 18 won by Jack Nicklaus.

Woods won his most recent major title at the 2008 US Open at Torrey Pines and has also won the PGA event staged at Torrey Pines seven times. No other PGA player has won so many times on a single course.

A fog delay Saturday led to the Monday finish, with darkness halting Woods on Sunday after seven holes.

Woods completed a final-round par 72 Monday despite going three-over in the closing stretch, finishing 72 holes on 14-under par 274. Brandt Snedeker, the 2012 winner, and Josh Teater shared second on 278.

Woods had two bogeys and a double bogey between the 14th and 17th holes, but managed a par at the par-5 18th to close out the victory.

"It got a little ugly toward the end," Woods said. "I started losing my patience with slow play and lost my concentration there a little bit. But I was able to get my par there at 18 and got the win."

After missing the cut in his season opener at Abu Dhabi, Woods collected his first victory since last July at the US PGA National at Congressional.

With new 'Star Wars' on tap, Lucasfilm bails on Episodes II and III in 3D

With the creative team for "Star Wars Episode VII" now in place, Lucasfilm and Disney appear to be using the forward movement on that project as an excuse to shelve plans to release 3D versions of Episodes II and III.

In a news post today on StarWars.com, Lucasfilm announced the abandoning of the release of the 3D versions of the two prequel films.

"Lucasfilm has decided to postpone this fall's scheduled release of 'Star Wars' Episodes II and III in 3D," it wrote today. "Given the recent development that we are moving forward with a new 'Star Wars' trilogy, we will now focus 100 percent of our efforts on 'Star Wars: Episode VII' in order to ensure the best possible experience for our fans. We will post further information about our 3D release plans at a later date.

In the weeks since Disney announced the purchase of Lucasfilm for $4 billion, it has made additional news by hiring "Toy Story 3" writer Michael Arndt to pen the screenplay for the next "Star Wars" film, and last week, got the entire "Star Wars" universe excited -- for better or worse -- by hiring "Star Trek" director and "Lost" creator J.J. Abrams to direct "Episode VII."

Lucasfilm released Episode I in 3D a year ago.

Space Pictures This Week: Martian Gas, Cloud Trails

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.
