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.

UN aid call as Philippines typhoon toll tops 600

MANILA: The United Nations is set to launch a global appeal Monday for aid for millions of Philippine typhoon victims as the death toll surged past 600, with nearly 800 people still missing.

UN Humanitarian Coordinator Luiza Carvalho will outline plans for an immediate aid package as well as long-term support for the southern region of Mindanao, hardest hit by Typhoon Bopha, UN spokeswoman Imogen Wall said.

"Five million people were affected and they need express assistance," Wall, spokeswoman for the UN Office for the Coordination of Humanitarian Affairs, told AFP.

"Their priority needs are food, water and shelter but there's also a big emphasis on helping people's livelihood," she said.

"So many farmers have lost their crops and it's such a poor area. People need to earn money immediately and agriculture has to be rehabilitated," she added.

She declined to give an estimate of the needs of the hard-hit region, the centre of both the country's banana as well as gold mining industries.

But she said a number of villages were still completely cut off and not receiving any aid, a week after the typhoon struck.

The region would need sustained assistance for at least six months, she added.

Carvalho is due to outline the aid plans at 0730 GMT in Davao city, near the area worst hit by the typhoon.

The civil defence office in Manila said 647 corpses had been recovered after landslides and floods obliterated entire communities in the typhoon's path.

A total of 780 people are still missing, including about 150 fishermen from General Santos, the country's tuna capital, who had put to sea ahead of Bopha's landfall.

Civil defence chief Benito Ramos has said many of those missing could be among the hundreds of unidentified bodies, many of them bloated beyond recognition.

Yahoo, NBC Sports team up to share broadcast sports, news

Yahoo and the NBC Sports Group announced a content and promotion partnership this evening that combines the Web company's sports reporting with NBC's television presence and digital resources.

The alliance will include original video content that will appear on both Yahoo Sports and NBCSports.com, live streams of events such as "Sunday Night Football," and adoption of Yahoo Sports' fantasy platform as the exclusive game provider for NBC Sports' news and information site Rotoworld.

Financial details of the deal were not revealed. The two will maintain separate Web sites and newsrooms but will collaborate on big sports news, both on the Internet and TV.

The pair touted the partnership as expanding NBC Sports' digital footprint.

"Through our growing television and digital platforms, the Yahoo Sports partnership dramatically expands the digital reach of NBC Sports around the biggest sporting events," Mark Lazarus, chairman of NBC Sports Group, said in a statement. "We are committed to continually growing this alliance for the benefit of both parties, our sports-property partners, and, most importantly, sports fans."

The deal is part of Yahoo's ambitions to raise its profile in other media. Yahoo and CNBC announced a partnership to jointly distribute content and programming across their networks. Like the NBC Sports deal, Yahoo and the business news channel partnered on creating co-branded, original videos that will appear on Yahoo Finance and CNBC.com.

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, confirm that the remains of the private jet carrying Jenni Rivera have been found, with no survivors. Rivera, 43, was one of seven passengers.

Rivera's father, Pedro, confirmed the news of his daughter's passing to reporters stationed outside of his home in Lakewood, Calif., where several family members are gathered, including Rivera's mother Rosa and her eldest daughter Chiquis, who has still not made any statements. Rivera's father reportedly received the news via telephone from his son, singer Lupillo Rivera, who was in Mexico at the time of the jet's disappearance. "This is the first tragedy of this kind that we suffer as a family," Rivera's father told reporters on Sunday evening. "I hope people remember her as she was - someone who was straight with the world."

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, which dates back to 1969, 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."

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.

China's inflation rises to 2.0 percent in November

BEIJING: China's inflation rate accelerated slightly to 2.0 percent in November, the National Bureau of Statistics said on Sunday.

It is the first increase in the consumer price index since August. Inflation stood at 1.7 percent in October.

The result compares with a median 2.1 percent forecast for November in a survey of 12 economists by Dow Jones Newswires.

Producer prices -- which measure the cost of goods as they leave factories -- declined 2.2 percent year-on-year, falling for the ninth straight month, the data showed. Producer prices fell 2.8 percent in October.

China's economy grew 7.4 percent in the third quarter until the end of September, its weakest performance in more than three years and the seventh straight quarter of slowing expansion.

But recent numbers, including manufacturing, trade and industrial output, have led to optimism among economists that the world's second biggest economy is rebounding.

China is scheduled to announce industrial production, retail sales and fixed asset investment figures for October later on Sunday.

Inflation rose 2.0 percent year-on-year in August, but fell to 1.9 per cent in September.

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.

Gay Marriage: Will Justices Follow Popular Opinion?

The Supreme Court's announcement that it would hear two cases challenging laws prohibiting same-sex marriage has reinvigorated one of the most hotly contentious social debates in American history, a debate that has been fueled by a dramatic change in attitudes.

With some states taking significant steps towards legalizing gay marriage, the hearings come at a critical moment.

This week in Washington State, hundreds of same-sex couples lined up to collect marriage licenses after Gov. Christine Gregoire announced the passing of a voter-approved law legalizing gay marriage.

"For the past 20 years we've been saying just one more step. Just one more fight. Just one more law. But now we can stop saying 'Just one more.' This is it. We are here. We did it," Gregoire told a group of Referendum 74 supporters during the law's certification.

Washington is just the most recent of several states to pass legislation legalizing same-sex marriage, signifying a significant departure from previous thinking on the controversial subject.

READ: Court to Take Up Same-Sex Marriage

A study by the Pew Research Center on changing attitudes on gay marriage showed that in 2001 57 percent of Americans opposed same-sex marriage, while 35 percent of Americans supported it.

The same poll shows that today opinions have greatly shifted to reflect slightly more support for same-sex marriage than opposition -- with 48 percent of Americans in favor and 43 percent opposed.

In fact, just two years ago, 48 percent of Americans opposed same-sex marriage while only 42 percent supported it -- indicating that opinions have changed dramatically in the last couple of years alone.

Check Out Same-Sex Marriage Status in the U.S. State By State

It's hard to imagine that only 16 years ago, the fervent gay marriage debate led to the conception of the Defense of Marriage Act, which defines marriage as a union solely held between a man and a woman.

While debating the Defense of Marriage Act in September 1996, former Sen. Robert Byrd said: "If same-sex marriage is accepted, then the announcement will be official: America will have said that children do not need a mother and a father. Two mothers or two fathers will be OK. It'll be just as good. This would be a catastrophe."

Even a few short years ago a newly-elected President Obama did not support the legalization of gay marriage. It wasn't until earlier this year, at the end of hiss first term and with the impending election in sight, that the president told ABC's Robin Roberts the he'd "been going through an evolution on this issue."

Obama went on to attribute his shift in stance to the influence of his daughters.

"You know, Malia and Sasha, they've got friends whose parents are same-sex couples. It wouldn't dawn on them that somehow their friends' parents would be treated differently," he said. "That's the kind of thing that prompts -- a change in perspective."

Obama isn't the only one to experience an evolution in thinking on the matter of gay marriage. Attitudes towards same-sex marriage have shifted dramatically over the past decade across the board, particularly in the past few years.

Gone are the days when a majority of people opposed same-sex marriage; the days when gay politicians and supporters of same-sex marriage could not get elected.

Today, nine states and the District of Columbia allow same-sex unions -- a number likely considered inconceivable just a few short years ago. And yet, the same-sex marriage debate still begs for the answering of a question: Will this newfound public opinion, largely driven by young people, women and Democrats, have an effect on the Supreme Court's ultimate decision on the matter?

"I think (gay marriage is) just not a big deal for a lot of young people," Elizabeth Wydra of the Constitutional Accountability Center says. "The justices are human beings so they're not completely immune to public opinion. ... I think the real question for them is going to be do they want to be on the wrong side of history?"
