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.

N. Korea replacing faulty rocket stage: report

SEOUL: North Korea is replacing a faulty section of a long-range rocket in a bid to put its launch schedule back on track, and is receiving help from Iranian missile experts, a South Korean newspaper reported Monday.

North Korea had said Sunday it was considering delaying the launch -- slated for some time between December 10-22 -- because of unspecified "problems" uncovered by technicians at its Sohae satellite launch station.

But the Chosun Ilbo newspaper on Monday cited new satellite images that suggested the faulty component was being replaced to allow the launch to go ahead.

"A new third stage of the North's three-stage missile Unha-3 was seen being moved Saturday afternoon from a missile plant... towards the launch site," the newspaper quoted an unidentified government source as saying.

The South's Yonhap news agency quoted a separate government source as saying a component was being moved but that it was unclear what kind.

"We have yet to analyse information that it is a third stage of the rocket or other parts," the Yonhap source said.

North Korea says the rocket launch is a peaceful mission aimed at putting a satellite in orbit.

The United States and its allies view it as a disguised ballistic missile test banned under UN resolutions prompted by the North's nuclear tests in 2006 and 2009.

In a separate report Monday, the Chosun Ilbo -- known for its comprehensive North Korean coverage -- said a group of Iranian missile experts was in North Korea offering technical assistance for the planned launch.

The Iranians were invited after Pyongyang's last rocket launch in April ended in failure, the newspaper said, citing a Seoul government official.

"A car seen at the... launch site has been spotted driving back and forth from the accommodation facility nearby. It is believed to be carrying Iranian experts," the official said.

Earlier this month, Japan's Kyodo news agency quoted a western diplomatic source as saying Iran had stationed defence personnel in North Korea since October to strengthen cooperation in missile and nuclear development.

North Korea and Iran are both subject to international sanctions over their nuclear activities and their governments share a deep hostility towards the United States.

Leaked US diplomatic cables in 2010 showed that US officials believe Iran has acquired ballistic missile parts from North Korea. A 2011 UN sanctions report said the two countries were suspected of sharing ballistic missile technology.

On Sunday, the North's Korean Committee of Space Technology said its scientists were "seriously examining the issue of readjusting the launching time of the satellite for some reasons."

The committee gave no further details, but analysts suggested potential technical troubles. A US think-tank, the US-Korea Institute at Johns Hopkins University, said Friday that preparations may have been delayed by heavy snow.

Some analysts said the new leader, Kim Jong-Un, may have been rushing the event to mark the first anniversary of the death of his father and former leader Kim Jong-Il on December 17.

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.

Fiscal Cliff Talks: Boehner, Obama Meet Face-to-Face

For the first time in more than three weeks, President Obama and House Speaker John Boehner met face-to-face today at the White House to talk about avoiding the fiscal cliff.

White House Principal Deputy Press Secretary Josh Earnest would offer no details saying only, "The lines of communication remain open."

Erskine Bowles, the co-creator of a debt reducing plan, who was pessimistic a couple weeks ago, said he likes what he's hearing.

"Any time you have two guys in there tangoing, you have a chance to get it done," Bowles said on CBS's "Face the Nation."

The White House afternoon talks, conducted without cameras or any announcement until they were over, came as some Republicans were showing more flexibility about approving higher tax rates for the wealthy, one of the president's demands to keep the country from the so-called fiscal cliff -- a mixture of across-the-board tax increases and spending cuts that many economists say would send the country back into recession.

Fiscal Cliff Battle: President Obama vs. Speaker John Boehner Watch Video

"Let's face it. He does have the upper hand on taxes. You have to pass something to keep it from happening," Sen. Bob Corker of Tennessee said on "FOX News Sunday."

This comes after the White House moderated one of its demands about tax rate increases for the wealthy.

The administration was demanding the rate return to its former level of 39.6 percent on income above $250,000. The so-called Bush tax cut set that rate at 35 percent. But Friday, Vice President Joe Biden signaled that rate could be negotiable, somewhere between the two.

"So will I accept a tax increase as a part of a deal to actually solve our problems? Yes," said Oklahoma Republican Tom Coburn on ABC's "This Week."

The problems the senator was referring to are the country's entitlement programs. And there was some progress on that front, too.

A leading Democrat said means testing for Medicare recipients could be a way to cut costs to the government health insurance program. Those who make more money would be required to pay more for Medicare.

"I do believe there should be means testing, and those of us with higher income and retirement should pay more. That could be part of the solution," Sen. Dick Durbin of Illinois said on NBC's "Meet the Press."

But Durbin said he would not favor raising the eligibility age from 65 years old to 67 years old, as many Republicans have suggested.

The White House and the speaker's office released the exact same statement about the negotiating session. Some will see that as a sign of progress, that neither side is talking about what was said behind closed doors.

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.

Boehner in hot seat in game of fiscal chicken

WASHINGTON: With room for maneuver slipping away, top US Republican John Boehner is in a bind over how to avoid going over the fiscal cliff: embrace higher taxes and earn conservatives' ire, or scupper a deal and incur Americans' wrath.

Another option, one that few non-partisans see as very viable, is for President Barack Obama to cave in and agree to Republican demands not to raise taxes, even for the wealthiest Americans.

A likelier resolution is a compromise with the White House that avoids the early January shock of automatic spending cuts coupled with tax hikes on nearly all Americans, while laying out enough deficit reduction that eases concern about the country's financial well-being.

In the game of political chicken to see whether Democrats or Republicans blink first, perhaps the trickiest role of all rests with Speaker of the House Boehner, who along with Obama is the principal in the negotiations.

Boehner's guidance of the Republican position in coming days and weeks could signal much about party direction in the wake of an election that saw flagbearer Mitt Romney -- who advocated slashing tax rates across the board -- defeated by Obama.

"To say Boehner is between a rock and a hard place is minimizing the problem he faces," Boston University professor and longtime political consultant Tobe Berkovitz told AFP.

"Boehner is trying to keep public opinion about Republicans from totally cratering, and at the same time keep the Tea Party hardcore conservatives from totally abandoning the party."

Conservative Republican Trent Franks agrees that "our speaker is in an enormously difficult position."

"And I think he's doing the best he can," the congressman told National Public Radio. "That doesn't mean that what he finally arrives at will be something that I can support or it won't. You know, I don't know."

Few people other than Boehner and Obama know the true state of negotiations in what appears as a well-choreographed campaign to thrash out a last-minute deal.

Discussions appear to have stalled, though, and Boehner has accused Obama of having "wasted another week" by not pushing talks forward.

This weekend Boehner "will be waiting for the White House to respond to our serious offer about averting the fiscal cliff," his spokesman Michael Steel told AFP.

Obama has proposed US$1.6 trillion in new taxes over the next decade from higher rates on the wealthiest two percent of Americans.

Republicans countered with a plan for US$800 billion in tax revenue raised by closing loopholes and ending some deductions. Both plans were rejected.

A Democratic official said Saturday that "nothing has changed since yesterday."

Polls show most Americans want to see taxes rise on the wealthy.

With Obama winning re-election on November 6, and his Democrats gaining seats in both the House and Senate, Republicans concede privately -- and some publicly -- that the Democrats have the upper hand.

"President Obama pretty well holds all the cards in this negotiation," Republican Senator Ron Johnson told Fox News.

"If he wants to have tax increases or tax rates go up, I don't see how Republicans can stop him."

Public trust is not in Boehner's favour. A Washington Post/Pew poll this week showed 53 percent of Americans would blame Republicans should the economy dive off the cliff; 27 percent would blame Democrats.

In his weekly address Saturday, Obama said he was willing to find ways to reduce health costs and make more entitlement spending cuts, but as for asking "the wealthiest Americans to pay higher tax rates -- that's one principle I won't compromise on."

Potential future Republican leaders like Senator Marco Rubio are unlikely to want to bend to White House's will.

Rubio, a possible 2016 presidential candidate, gave the Republican response to Obama's address -- and said "tax increases will not solve our US$16 trillion debt."

Boehner has said that, too, but his position is tenuous. On Friday he left open the possibility for compromise on a tax rate rise.

In past negotiations, such as last December's battle over extending the payroll tax holiday, some Republicans felt Boehner gave away too much.

Hashtags on Twitter -- #boehnermustgo, #fireboehner -- have recently left little doubt that some Republicans are fed up with his handling of the talks.

With conservatives demanding unity on taxes, Boehner faces the prospect of revolt from his right flank should he agree to a deal that would raise high-end rates.

Berkovitz said Republicans face two options if they want to avoid the cliff: negotiate and compromise, or hold their noses and "give Obama what he wants. If it goes south, take the election victory in two years and maybe four years."

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?"
