Female lemurs avoid the wrong love in the dark

IT IS the ultimate voice-recognition system. Without ever meeting him, a female lemur still knows the call of her father.

The ability to identify family members is important to avoid inbreeding. For large-brained mammals like apes that engage in complex social interactions this is relatively straightforward. Now, a team has shown that nocturnal grey mouse lemurs appear to do the same, even though lemurs are reared exclusively by their mothers (BMC Ecology, doi.org/jvx).

Study leader Sharon Kessler of Arizona State University in Tempe, believes that the young lemurs may associate calls similar to their own, or to those of male siblings, with their fathers.

Obama meets with top Republican on fiscal cliff

WASHINGTON: President Barack Obama and House of Representatives speaker John Boehner met Sunday to discuss the so-called impending fiscal cliff of steep tax hikes and spending cuts.

No details of the talks were given, but a statement from Boehner's office said "the lines of communication remain open."

That sounded relatively upbeat compared to Boehner's statement on Friday, when he reported "no progress" in deficit talks. He accused the White House of recklessly pushing the country to the fiscal brink over tax hikes.

The last time the two leaders had spoken was Wednesday, by telephone.

The so-called fiscal cliff refers to a combination of severe tax increases and spending cuts due to kick in automatically in January if the president and Congress don't find a compromise plan to cut the deficit first.

Economists warn that careening over the fiscal cliff would throw the country back into a recession.

Obama sent Treasury Secretary Timothy Geithner to Capitol Hill last week with an opening gambit, proposing $1.6 trillion in new tax revenues over the next decade, mainly from higher tax rates on the wealthiest two percent of Americans.

A Republican counter-offer included a plan for $800 billion in tax revenue raised through closing loopholes and ending some deductions. Both plans have been rejected.

In his weekly address Saturday, Obama said he was willing to find ways to reduce health costs and make more entitlement spending cuts as sought by the Republicans.

But he said asking "the wealthiest Americans to pay higher tax rates -- that's one principle I won't compromise on."

Google, Facebook ask court to reject patents on abstract ideas

As patent spats continue to command much of the tech world's attention and corporate resources, a group of prominent companies is taking a stand against a practice it sees as hobbling innovation.

Google, Facebook, Zynga and five other tech giants filed an amicus brief with the U.S. State Court of Appeals for the Federal Circuit on Friday, asking the court to reject the patents central to a lawsuit between two financial institutions. CLS Bank sued Alice Corp. for infringing on four patents covering a computerized method of having a third-party hold funds in escrow on behalf of two other contracting parties.

The 37-page brief (see below), also signed by Dell, Intuit, Homeaway, Rackspace, and Red Hat, argues that combining phrases such as "on a computer" or "over the Internet" with an abstract idea doesn't deserve a patent. The brief said the issue was "critically important in the high-tech context" and that granting patents stymie innovation:

Many computer-related patent claims just describe an abstract idea at a high level of generality and say to perform it on a computer or over the Internet. Such barebones claims grant exclusive rights over the abstract idea itself, with no limit on how the idea is implemented. Granting patent protection for such claims would impair, not promote, innovation by conferring exclusive rights on those who have not meaningfully innovated, and thereby penalizing those that do later innovate by blocking or taxing their applications of the abstract idea.

Calling abstract patents a "plague in the high-tech sector," the brief concludes that, "It is easy to think of abstract ideas about what a computer or website should do, but the difficult, valuable, and often groundbreaking part of online innovation comes next: designing, analyzing, building, and deploying the interface, software, and hardware to implement that idea in a way that is useful in daily life. Simply put, ideas are much easier to come by than working implementations."

The brief comes as companies grapple with a rash of lawsuits based on patents that are secured for the purpose of extracting licensing fees from other companies rather than making products based on the patents. A study released earlier this year found that patent infringement lawsuits are on the rise, costing U.S. companies $29 billion in 2011.

The explosion in patent lawsuits, especially in the software and pharmaceutical industries, led one judge presiding over high-profile cases to declare that "patent protection is on the whole excessive and that major reforms are necessary."

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Remains of Banda Superstar Jenni Rivera's Jet Reported Found

UPDATED: Multiple reports, including one from Gerardo Ruiz Esparza, Mexico's Secretary of Communications and Transports, claim that the remains of the private jet carrying Jenni Rivera have been found, with no survivors. Rivera, 43, was one of 7 passengers.

Rivera's parents are believed to be en route to Mexico. Her brother, fellow singer Lupillo Rivera, and eldest daughter Chiquis have still not made any statements.

Celebrity reactions on Twitter have poured in since news of the disappearance of Rivera's jet, including Paulina Rubio (who was set to co-host the Mexican edition of The Voice with Rivera) William Levy, Joan Sebastian, Ricky Martin, and others.

Mexican officials have confirmed the disappearance of a private jet carrying regional Mexican music superstar Jenni Rivera that took off from the northern Mexican city of Monterrey at 3:15 a.m. local time on Sunday and fell off the radar 10 minutes (or 62 miles) after take-off.

The Learjet 25 jet is believed to have been carrying seven people – five passengers and two pilots. It was headed for Toluca International Aiport, located outside of Mexico City, where it was meant to arrive at 4:40 a.m. An official search for the jet was initiated at sunrise.

Rivera's publicist Arturo Rivera and her make-up artist Jacob Yebale are believed to have been on that flight. Their most recent tweets are of photos from Rivera's concert in Monterrey on Saturday night.

The Mexican American singer's most recent tweet is a re-tweet of what appears to be a fan's message.

Rivera was due in Toluca this evening for the taping of a Mexican TV show, La Voz. Televisa has canceled tonight's show given Rivera's disappearance.

Known as La Diva de la Banda and beloved by fans on both sides of the border, Rivera, 43, has had a groundbreaking career in regional Mexican music, selling some 15 million records. Among her many feats in a male-dominated genre, she made history in September 2011 when she sold out the Staples Center in Los Angeles, the first female regional Mexican artist to do so. Her reality show on mun2, I Love Jenni, is one of the network's highest rated shows. Rivera made her film debut at the 2012 Sundance Film Festival in the indie family drama Filly Brown, due in theaters in January 2013.

The Long Beach, Calif.-born singer's personal life has often called for as much attention as her career. A mother of five, Rivera had filed for divorce from baseball player Esteban Loaiza in October after two years of marriage, citing "irreconcilable differences." Soon after, rumors of an affair between Loaiza and Rivera's own daughter Chiquis surfaced, which Chiquis addressed on Twitter in October by saying, "I would NEVER do that, Ever! That's a horrible accusation."

The search for Rivera's jet continues. This is a developing story.

Kenyan elephant numbers plummet by 1000 in four years

IT'S a case of up then down for Kenya's second largest population of elephants. After a promising growth spurt, the elephants are now dying faster than they are being born. The decline is being blamed on illegal poaching, driven by Asia's demand for ivory.

The Kenya Wildlife Service recently conducted a census of the Samburu/Laikipia population, the country's second largest. It found that the population lost over 1000 elephants in just four years, and now stands at 6361. Previous censuses in 1992, 1998, 2002 and 2008 had revealed a growing population, which appears to have peaked at 7415 in 2008.

Poaching is suspected. A July report by three conservation groups found that it has been on the rise across Africa since 2006. Poaching is also spreading eastwards from central Africa into countries like Kenya, says Richard Thomas of TRAFFIC in Cambridge, UK, one of the three groups that drafted the report. The July report found that more than half of all elephants found dead in Africa in 2011 had been illegally killed.

The rise in poaching appears to be driven by increasing affluence in China and Thailand, where ivory is often used to make religious sculptures and other decorations.

Organised criminal gangs have capitalised on this increased demand. "If it's worth someone's while to smuggle the ivory, they'll take the risk," Thomas says. There is evidence that gangs are moving into Kenya to hunt elephants.

Football: Evergreen Totti cheers Romans

ROME: A double strike from Francesco Totti helped push AS Roma into the top four in Serie A on Saturday, proving instrumental in an entertaining 4-2 home win over Fiorentina, who missed the chance to leapfrog Inter Milan into third.

Brazilian defender Leandro Castan gave Roma a seventh-minute lead but it was the sterling efforts of 36-year-old skipper Totti which had the home fans singing his praises as Roma moved onto 29 points, the same tally as Saturday's opponents as well as city rivals Lazio.

Juventus and Napoli may be setting the title pace but Roma proved they can aspire at least to be in the mix after their ninth win of the campaign while they handed Fiorentina a third loss.

Greek star Panagiotis Tachtsidis did the spadework for the opener in heading on a Totti freekick with Castan only having to walk the ball in.

Totti then provided the fireworks for the "Giallorossi," who have now netted a league-leading 38 goals in 16 games.

Facundo Roncaglia briefly levelled for the visitors from Florence in beating the offside trap on 14 minutes but five minutes after that Totti pounced following a superb interchange with Mattia Destro and then completed his brace in first half injury time with a shot from 20 metres for his 219th Serie A goal.

Mounir El Hamdaoui put the visitors back in the hunt a minute after the restart, the Moroccan substitute heading in a Borja Valero cross.

But Osvaldo made the points safe on 89 minutes - Totti providing another assist - as Fiorentina went down to their first league loss since the end of September.

Earlier, Atalanta thanked first-half goals from Denis and Peluso to edge out Parma 2-1.

On Sunday, Juve travel to Palermo with Napoli in for a tough test at Inter while AC Milan are away to Torino.

Lazio for their part are at Bologna on Monday.

Handcuffs that give you an electric shock?

Progress?

(Credit:
Patent Bolt)

Sometimes an invention comes along that makes you excited about the future.

For a long time, it seems that handcuffs have been stuck in the movies of old. They restrain you, but, odd for our interactive world, that's all they seem to do.

Might I tempt you toward futuristic handcuffs that will offer you a small involuntary judder?

I am grateful to Gizmodo for discovering that Patent Bolt has lucked upon a patent that offers bound(less) excitement.

For these are handcuffs that offer surprises. Indeed, they might make the idea of being tased, bro, not quite so bad.

The patent is called "Apparatus and System For Augmented Detainee Restraint."

The augmentations it offers are truly quite something. You see, these handcuffs are "configured to administer electrical shocks when certain predetermined conditions occur."

These shocks might be "activated by internal control systems or by external controllers that transmit activation signals to the restraining device."

This progressive tool is the brainchild of Scottsdale Inventions.

More Technically Incorrect

And while you might be shocked or even excited by the idea of handcuffs with electric shock capabilities, might I move you further?

For Patent Bolt points out that this patent also allows for the idea of a substance delivery system. Yes, these handcuffs might also be used to, well, inject the detained with who knows what -- to achieve "any desired result."

Clearly, the desires of the detained and the detainer might differ. Yet, this patent allows for the possibility of the substance being in the form of "a liquid, a gas, a dye, an irritant, a medication, a sedative, a transdermal medication or transdermal enhancers such as dimethyl sulfoxide, a chemical restraint, a paralytic, a medication prescribed to the detainee, and combinations thereof."

Yes, you really did read the word "paralytic."

Naturally, some will be wondering whether, as in fine restaurants, the arresting officer will ask whether the detained has any allergies.

Some might be concerned, though that -- at least theoretically -- this creation might put quite some power into the hands of those who might not always be lucid or learned enough to use that power wisely.

Dallas Cowboys Player Arrested in Teammate's Death

Dallas Cowboys nose tackle Joshua Price-Brent was arrested on an intoxication manslaughter charge today after a single vehicle roll-over killed his passenger, Jerry Brown Jr., who had been a linebacker on the team's practice squad and his former teammate at the University of Illinois.

Price-Brent, 24, was allegedly speeding "well above" the posted 45 mph speed limit at about 2:21 a.m. when he hit a curb, causing his vehicle to flip at least one time before landing in the middle of a service road, Irving Police Department spokesman John Argumaniz said.

Authorities were alerted to the accident by several 911 callers, Argumaniz said. When police arrived, they found Price-Brent pulling Brown from his 2007 Mercedes, which had caught fire.

Brown, 25, was unresponsive and was transported to a local hospital, where he was pronounced dead, Argumaniz said.

It was not known where the men were coming from or where they were going, but Argumaniz said officers suspected alcohol may have been a factor in the crash and asked Price-Brent to perform field sobriety tests.

Kansas City Chiefs Player Jovan Belcher's Murder-Suicide Watch Video

"Based on the results of the tests, along with the officer's observations and conversations with Price-Brent, he was arrested for driving while intoxicated," Argumaniz said.

This is the second week in a row an NFL player has been accused of being involved in another person's death. Jovan Belcher of the Kansas City Chiefs killed his girlfriend early Dec. 1, then committed suicide while talking to team officials in the parking lot at Arrowhead Stadium.

Price-Brent was taken to a hospital for a mandatory blood draw where he was treated for minor scrapes, Argumaniz said. He was then booked on an intoxication manslaughter charge after it was learned Brown had died of injuries suffered in the crash.

It is expected that results from the blood draw could take several weeks, the police spokesman said.

Price-Brent is scheduled to be arraigned Sunday at 10 a.m., when bond will be set, police said.

The second-degree felony intoxication manslaughter charge carries a sentence of two to 20 years in prison and a $10,000 fine. It was not yet known whether Price-Brent had retained an attorney.

The 6-foot-2, 320-pound nose tackle left the University of Illinois as a junior for a career in the NFL. He was picked up by the Cowboys during the 2010 NFL supplemental draft and has played three seasons with the team.

The Cowboys are set to take on the Cincinnati Bengals in Ohio on Sunday.
