Obama Admin to Court: End Calif. Gay Marriage Ban

Solicitor General Donald B. Verrilli, plans to file a brief today with the Supreme Court in favor of challengers of Prop. 8, according to an administration source.

It would mark the first time that the Obama administration has come out in court against the California ballot initiative that defines marriage as between one man and one woman.

As far back as 2008, the president said that he thought Prop 8 was "divisive and discriminatory," but his Justice Department has never opined on its constitutionality. Because the DOJ is not a party to the case, it is not required to file a "friend of the court" brief, but the deadlines for briefs supporting the challengers to Prop 8 is tonight at midnight.

Theodore Olson, one of the lead lawyers challenging Prop 8, told reporters last week that he hoped the DOJ lawyers would take the opportunity to set down a legal position.

"However," Olson added, "whether they do or not, the president of the United States made it very clear in his inaugural address that we cannot rest in America until all civilians have equal rights under the law so, in a sense, the president has made that statement already."

Today, 39 states have laws restricting marriage to opposite-sex couples. This number includes voter-approved constitutional amendments in 30 states barring same sex marriage. Nine states allow gay marriage.

Quantum skyfall puts Einstein's gravity to the test

DIVIDING a falling cloud of frozen atoms sounds like an exotic weather experiment. In fact, it's the latest way to probe whether tiny objects obey Einstein's theory of general relativity, our leading explanation for gravity.

General relativity is based on the equivalence principle, which says that in free fall, all objects fall at the same rate, whatever their mass, provided the only force at work is gravity. That has been proven for large objects: legend has it that Galileo did it first by dropping various balls from the Tower of Pisa. Whether equivalence holds at quantum scales, where gravity's effects are not well understood, isn't clear. Figuring it out could help create a quantum theory of gravity, one of the biggest goals of modern physics.

Creating a quantum equivalent of Galileo's test isn't easy. In 2010 a team led by Ernst Rasel of the University of Hannover in Germany monitored a quantum object in free fall, by tossing a Bose-Einstein condensate (BEC) – a cloud of chilled atoms that behaves as a single quantum object and so is both particle and wave – down a 110-metre tall tower. Now they have split and recombined the wave – all before the BEC, made of rubidium atoms, reached the bottom. This produces an interference pattern that records the path of the falling atoms and can be used to calculate their acceleration (Physical Review Letters, doi.org/km6). The next step is to do the same experiment on a different kind of atom, with a different mass, to see if the equivalence principle holds.

The BEC can only be split for 100 milliseconds in the tower before hitting the bottom, so to allow tiny differences between the atom types to emerge, the work must be repeated in space, where the waves can be split for longer. By showing that a matter-wave can be split and recombined while falling, Rasel's result is a "major step" towards the space version, says Charles Wang of the University of Aberdeen, UK.

AIM not bidding for PAP town councils' tender

SINGAPORE: Action Information Management (AIM), which runs the People's Action Party (PAP) town councils' computer systems, will no longer operate the systems when its contract expires on April 30. It said on Wednesday that it will not participate in the latest tender exercise.

The arrangement between AIM, a company fully owned by the PAP, and the PAP town councils had caused controversy even though both parties had explained that the process by which the open tender was awarded to AIM was above board.

AIM Chairman S Chandra Das said: "Given that AIM had helped prepare the tender documents, it decided not to participate in the tender."

When contacted, Dr Teo Ho Pin, who is the Coordinating Chairman of the PAP town councils, confirmed the news: "AIM should not bid for this tender as they are involved in the tender specification preparation."

Dr Teo declined to reveal how many parties had collected the tender documents "as tendering is in progress".

In media reports last week, Mr Das declined to say whether AIM had - or would - bid for the tender, which was put up by the PAP town councils on February 4 and will close on Monday. Dr Teo had also said the latest tender was for developing a new town council management system. The previous tender - which was won by AIM in 2010 - was to sell and lease back computer software to the PAP town councils.

The saga began on December 14 after Aljunied-Hougang Town Council (AHTC) Chairman Sylvia Lim explained the town council's less-than-stellar performance in a management report.

Ms Lim, part of the Workers' Party team which took over management of the town council after the General Election in 2011, blamed the AHTC's poor performance on the need to develop new IT systems within two months of the PAP-owned AIM terminating its contract last August.

Her explanation was followed by a series of statements by the AHTC and AIM. Among other things, questions were raised about the termination of the contract and the fact that AIM won a tender to manage the computer systems used by the town councils.

Last month, Prime Minister Lee Hsien Loong announced that the Ministry of National Development will review the transaction. Among other things, the review will re-examine the fundamental nature of town councils, after much public debate about whether the town councils are public institutions or political organisations.

See a saber duel through Darth Vader's eyes

I've got a bad feeling about this.

In the "Star Wars" universe, Jedi and Sith usually settle a score with a good old-fashioned lightsaber duel. Even though all six movies featured lengthy confrontations filled with sizzling sabers, George Lucas never showed an angle of how that type of fight would appear through the eyes of a dueler.

Independent filmmakers The Stunt People created a first-person perspective video of Darth Vader fighting against a bearded Jedi who looks a lot like Obi-Wan Kenobi or Kyle Katarn. The clip runs short, but it may just inspire more excitement than the saber swinging that goes on in the real movies.

Choreography group Saber Combat developed the action, and the actors used modified Hasbro Force FX sabers to give the skirmish a real feel.

"Star Wars" enthusiasts might want to keep their expectations simple as some rather peculiar moves might be irksome. For example, when the Jedi has his back to Vader, the Sith Lord merely uses the Force to shove him away instead of plunging the saber in his back.

In addition, Vader force-chokes the Jedi at a very close range, which would likely not happen as the Sith doesn't mind personally choking people as demonstrated in "A New Hope." Regardless of these niggles, I wouldn't mind the newly appointed "Star Wars VII" director J.J. Abrams using a similar first-person style in the next movie.

Why African Rhinos Are Facing a Crisis

The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."

Holder Says Sequester Makes America Less Safe

The looming budget sequestration will make Americans less safe, Eric Holder says—and anyone who says otherwise isn't telling the truth.

"This is something that is going to have an impact on the safety of this country," the U.S. attorney general told ABC's Pierre Thomas on Wednesday in a wide-ranging, exclusive interview.

"And anybody that says otherwise is either lying or saying something that runs contrary to the facts," Holder said.

In his interview with ABC News, Holder reiterated warnings that if automatic spending cuts are triggered on Friday, the Justice Department will be handicapped in some of its most vital missions to prevent terrorist attacks and crime.

"The Justice Department is going to lose nine percent of its budget between now and September 30th. We're going to lose $1.6 billion. There are not going to be as many FBI agents, ATF agents, DEA agents, prosecutors who are going to be able to do their jobs," Holder said. "They're going to be furloughed. They're going to spend time out of their offices, not doing their jobs."

Portions of the interview will air Wednesday, February 27 on "ABC World News"

Eric Holder Says Homegrown Terror Threat Equals International: Exclusive Watch Video

Eric Holder Remembers Newtown, His Worst Day on the Job: Exclusive Watch Video

President Obama's Cabinet members have been warning for weeks that budget sequestration, which will begin Friday unless Obama and Republicans reach a deficit-reduction deal to avoid it, will leave their agencies shorthanded and could bring about disastrous consequences. Homeland Security Secretary Janet Napolitano and Transportation Secretary Ray LaHood have both appeared at the White House press briefing room to warn that furloughs for border-patrol agents, TSA agents and air-traffic controllers will mean weakened border and port security, longer waits in airport security lines, and logjammed air travel.

Holder, for his part, warned in a Feb. 1 letter to the Senate Appropriations Committee that cuts to the FBI, the ATF, the U.S. Marshals Service, and U.S. Attorneys would limit the department's capacity to investigate crimes. Cuts at the Bureau of Prisons, Holder wrote, would mean lockdowns and potential violence, with fewer staff members on hand. In a separate letter, FBI Director Robert Mueller warned that counterterrorism operations would be affected, with the possible elimination of some joint terrorism task forces with state and local police. Limited surveillance and slower response times would mean unwatched targets and the possibility that individuals on terrorism watch lists could gain entry to the U.S.

"FBI's ability to proactively penetrate and disrupt terrorist plans and groups prior to an attack would be impacted," Mueller wrote.

To Holder, the problem is simple.

"If you don't have prosecutors and agents doing what we expect them to do, and we won't if this thing actually takes place, we are going to be a nation that is going to be less safe. And that is simple fact," Holder said.

Some Republicans have claimed the Obama administration is exaggerating the sequester's purported consequences as a ploy to campaign for tax hikes. On "Fox News Sunday" this week, Sen. Tom Coburn, R-Okla., posited that federal agencies enjoy enough flexibility to avoid the worst consequences of the cuts.

On Wednesday, Holder acknowledged that the Justice Department will do what it can to avoid compromised security, while maintaining that furloughs can't be avoided.

Newly spotted comet to buzz Mars in 2014

There's a new comet in town, and it is making a beeline for Mars. If projections of its orbit are correct, the icy visitor will buzz the Red Planet in October 2014.

Dubbed C/2013 A1, the comet was discovered on 3 January by prolific comet hunter Robert McNaught at Siding Spring Observatory in New South Wales, Australia. Colleagues at the Catalina Sky Survey in Arizona found images of the comet in their catalogue that date back to 8 December 2012, giving additional information about its movements.

These observations allowed astronomers to trace the comet's likely path around the sun. The calculated trajectory has C/2013 A1 crossing Mars' orbit on 19 October 2014, according to Australian blogger Ian Musgrave.

That doesn't necessarily mean a collision will occur. The best estimates right now have the comet passing a safe distance of 900,000 kilometres from the Martian surface. Asteroid 2012 DA14 got much closer to Earth last week, skimming by at a distance of 34,400 kilometres. But with so little data in hand, the calculations are not precise. It's possible the comet will miss Mars by as much as 36 million kilometres - or it could smack right into the planet. "An impact can't be ruled out at this stage," Musgrave wrote.

From Earth, we should be able to see the comet and Mars sitting side by side through small telescopes. And from Mars, the comet could be as spectacular as the expected "supercomet" ISON, which will come into view this year and could outshine the full moon.

Assuming the comet's orbit brings it close enough - but not too close - to Mars, the object should be visible either by rovers on the surface or the armada of Mars-orbiting satellites, which have a history of snapping spectacular shots of the Red Planet and its neighborhood.

Dollar edges higher as Bernanke confirms stimulus

NEW YORK: The dollar edged higher Tuesday against the euro after Ben Bernanke confirmed the US Fed's stimulus program would continue, while the yen traded flat ahead of the nomination of a new Bank of Japan chief.

At 2200 GMT the euro was at $1.3061, compared to $1.3065 late Monday. The euro remained under pressure after Italy's inconclusive election, which some fear could lead to more political trouble and policy stalemate in the country.

"Political uncertainty has increased in Italy following the election results weighing upon the euro and risk assets," said Lee Hardman, currency analyst at the Bank of Tokyo-Mitsubishi UFJ in London.

In Washington, Federal Reserve Chairman Bernanke quelled speculation of an early end to quantitative easing when he told a Senate panel that the Fed's stimulus program was having an impact and was still needed.

He said inflation remained subdued and the Fed was keeping its eye on any potentially risky behavior in the market due to low-interest rates.

The Fed policy board "remains confident that it has the tools necessary to tighten monetary policy when the time comes to do so," he added.

The yen was barely changed against the dollar at 91.93, and the euro was at 120.08 yen compared to 120.12 yen late Monday.

Markets were waiting for confirmation of who would be named to head the bank of Japan, after newspapers reported Monday that Asian Development Bank chief Haruhiko Kuroda, an advocate of a lower yen, would be named.

The British pound fell further, to $1.5126 from $1.5166 late Monday. The dollar was little changed on the Swiss franc, at 0.9315 francs.

Adobe issues emergency patch for zero-day Flash vulnerabilities

Adobe Systems released a security update today that addresses a trio of vulnerabilities in Flash, two of which it said were already being exploited by hackers.

Today's surprise update -- the company's third for the browser plugin this month -- patches holes "that could cause a crash and potentially allow an attacker to take control of the affected system," Adobe said in a security bulletin.

"Adobe is aware of reports that CVE-2013-0643 and CVE-2013-0648 are being exploited in the wild in targeted attacks designed to trick the user into clicking a link which directs to a website serving malicious Flash content," the advisory stated, identifying the vulnerabilities by their Common Vulnerabilities & Exposures. The exploit for CVE-2013-0643 and CVE-2013-0648 is designed to target the
Firefox browser."

Adobe assigned a Priority 1 rating to the vulnerabilities being exploited on Windows and
Mac OS X and advised users of both operating systems to install the update within 72 hours. That rating -- Adobe's highest threat level -- identifies "vulnerabilities being targeted, or which have a higher risk of being targeted, by exploit(s) in the wild." The bulletin also assigned the Flash vulnerability facing Linux users a Priority 3 rating, which refers to "a product that has historically not been a target for attackers."

Adobe recommends users update to the latest versions:

• Users of Adobe Flash Player 11.6.602.168 and earlier versions for Windows and Adobe Flash Player 11.6.602.167 and earlier versions for Macintosh should update to Adobe Flash Player 11.6.602.171.


• Users of Adobe Flash Player 11.2.202.270 and earlier versions for Linux should update to Adobe Flash Player 11.2.202.273.
  


• Flash Player installed with Google Chrome will automatically be updated to the latest Google Chrome version, which will include Adobe Flash Player 11.6.602.171 for Windows, Macintosh and Linux.


• Flash Player installed with Internet Explorer 10 for
  Windows 8 will automatically be updated to the latest version of Internet Explorer 10, which will include Adobe Flash Player 11.6.602.171 for Windows.

The update is Adobe's third this month and its second emergency update in less than three weeks. A fix for two zero-day threats issued on February 8 addressed vulnerabilities that affected all versions of Flash on Windows, Mac, Linux, and Android.

A History of Balloon Crashes

A hot-air balloon exploded in Egypt yesterday as it carried 19 people over ancient ruins near Luxor. The cause is believed to be a torn gas hose. In Egypt as in many other countries, balloon rides are a popular way to sightsee. (Read about unmanned flight in National Geographic magazine.)

The sport of hot-air ballooning dates to 1783, when a French balloon took to the skies with a sheep, a rooster, and a duck. Apparently, they landed safely. But throughout the history of the sport, there have been tragedies like the one in Egypt. (See pictures of personal-flight technology.)

1785: Pioneering balloonist Jean-Francois Pilatre de Rozier and pilot Pierre Romain died when their balloon caught fire, possibly from a stray spark, and crashed during an attempt to cross the English Channel. They were the first to die in a balloon crash.

1923: Five balloonists participating in the Gordon Bennett Cup, a multi-day race that dates to 1906, were killed when lightning struck their balloons.

1924: Meteorologist C. LeRoy Meisinger and U.S. Army balloonist James T. Neely died after a lightning strike. They had set off from Scott Field in Illinois during a storm to study air pressure. Popular Mechanics dubbed them "martyrs of science."

1995: Tragedy strikes the Gordon Bennett Cup again. Belarusian forces shot down one of three balloons that drifted into their airspace from Poland. The two Americans on board died. The other balloonists were detained and fined for entering Belarus without a visa. (Read about modern explorers who take to the skies.)

1989: Two hot air balloons collided during a sightseeing trip near Alice Springs, Australia. One balloon crashed to the ground killing all 13 people on board. The pilot of the other balloon was sentenced to a two-year prison term for "committing a dangerous act." Until today, this was considered the most deadly balloon accident.

2012: A balloon hit a power line and caught fire in New Zealand, killing all 11 on board. Investigators later determined that the pilot was not licensed to fly and had not taken  proper safety measures during the crash, like triggering the balloon's parachute and deflation system.

2012: A sightseeing balloon carrying 32 people crashed and caught fire during a thunderstorm in the Ljubljana Marshes in Slovenia. Six died; many other passengers were injured.
