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.

Football: Barca legend Messi beats Mueller record

MADRID: Lionel Messi surpassed Gerd Mueller's record of 85 goals in a calendar year with a first-half double that helped his side to an important 2-1 win at Real Betis on Sunday.

The Argentinian moved up to 86 goals in 2012 but was only given the go-ahead to play against Betis before the game after injuring his knee in the midweek Champions League game against Benfica.

He beats the German legend's record set in 1972, and now has 23 in the league this season, six more than Radamel Falcao who hit five goals for Atletico in their win.

It did not take long for Messi to equal Mueller's record with his side's first real attack on 16 minutes, making a diagonal run across the Betis defence before hitting a left footed shot into the right hand corner.

His history-making moment came nine minutes later when he struck from almost an identical position after good play from Adriano and Andres Iniesta.

Betis had started and finished the better side in Seville, Salva Sevilla had a header well saved by Victor Valdes on three minutes and they hit the woodwork on three occasions in the second-half.

Adrian in the Betis goal then made an acrobatic save to deny Xavi Hernandez, and the home side appeared out of the game until substitute Alvaro Vadillo played a clever pass to Ruben Castro who finished coolly to reduce Barca's lead before the interval.

Valdes saved Barca six minutes into the second period, plucking a left-wing volley from Sevilla from under the crossbar.

The game continued from end-to-end at a frantic pace without many clear-cut chances until Barca's Javier Mascherano struck his own post whilst trying to clear a corner with twenty minutes remaining.

Jorge Molina then hit a post with a fierce shot while at the other end Adrian blocked well from Pedro Rodriguez before Jordi Alba hit the bar when he should have scored.

Barca were in danger of conceding until the end but held on for a vital three points where rivals Real Madrid lost 1-0 only two weeks ago.

The win keeps Barca six points ahead of Atletico Madrid at the top of La Liga who had earlier thrashed Deportivo La Coruna 6-0.

Falcao became the first La Liga player in a decade to score five to keep the pressure on Barca.

He had already hit a double along with a Diego Costa header to put Atletico out of sight by half-time, his second smashed on the half-volley direct from a throw-in.

He completed his hat-trick with a second-half penalty before hitting two more to make him the first player to hit five in a La Liga game since Fernando Morientes for Real Madrid against Las Palmas in 2002.

It was Atletico's eighth straight home win of the campaign.

A hapless looking Deportivo side remain bottom of the table on 11 points, level with Espanyol.

Also on Sunday, Levante thrashed Mallorca 4-0 with goals from Obafemi Martins, David Navarro, Ruben Garcia and Vicente Iborra to move into sixth position.

A first-half header from Aritz Aduriz, his ninth of the season, was enough for Athletic to edge a competitive encounter with Celta Vigo.

On Saturday Real Madrid kept in touch with a 3-2 win at Valladolid, but remain five points behind Atletico in third.

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.

Banda Superstar Jenni Rivera's Plane Missing

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 is believed to have been on that flight. His 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.

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.

Egypt's Morsi annuls controversial decree

CAIRO: Egyptian President Mohamed Morsi on Saturday annulled a decree he issued last month expanding his powers, an official told a Cairo news conference.

"The constitutional decree is annulled from this moment," said Selim al-Awa, an Islamist politician acting as spokesman of a meeting Morsi held earlier with other political leaders.

A referendum on a draft constitution would however still go ahead as planned on December 15, Awa said, explaining that constitutionally Morsi was unable to change the date.

The two issues -- the decree and the referendum -- were at the heart of anti-Morsi protests that have rocked Egypt in the past two weeks.

The controversial decree issued November 22 had put Morsi's decisions beyond judicial review -- a high-handed measure fiercely denounced as dictatorial by the opposition.

Opposition leaders demanded it be rescinded and the referendum be scrapped before they entered into any dialogue with Morsi to calm a crisis which exploded into street clashes this week that left seven people dead and hundreds injured.

Egypt's powerful military on Saturday warned Morsi and the opposition to sit down for talks, otherwise it would take steps to prevent a "disastrous" degradation of the situation.

Apple's U.S. Mac-making plan to create 200 jobs, says report

Various industry watchers are weighing in on Apple CEO Tim Cook's remark this week that the company will invest $100 million into making Macs in the U.S., with some saying the move will create 200 new jobs.

In an interview with Bloomberg on Thursday, Cook was asked what it would take to get Apple back to building products in the states. Cook said, in part: "Next year we are going to bring some production to the U.S. on the
Mac. We've been working on this for a long time, and we were getting closer to it. It will happen in 2013. We're really proud of it. We could have quickly maybe done just assembly, but it's broader because we wanted to do something more substantial."

That new stateside effort "sounds like a 200-job operation with about a million-unit output," Dan Luria told Bloomberg in a separate story last night. Luria studies factory operations as a labor economist at Michigan Manufacturing Technology Center in Plymouth, Mich., the news agency says. Bloomberg also reports that Michael Marks, former CEO of Flextronics International, a major global contract manufacturer, agrees with that estimate.

A plan by Lenovo to make PCs in North Carolina serves as a good template for how Apple's effort may play out, Bloomberg reports, citing Harvard Business School Professor Willy Shih. And the news agency adds that according to Lenovo's director of global supply-chain communications, Mark Stanton, manufacturing jobs pay about $32,000 a year, with skilled positions in the range of $65,000 a year.

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.
