From Cosmos/AFP:

TOKYO: Japanese researchers last week said they had found a way to make plant leaves absorb more carbon dioxide - an innovation that may help ease global warming and boost food production.

The Kyoto University team found that soaking germinated seeds in a protein solution raised the number of pores, or stomas, on the leaves that inhale CO2 and release oxygen, said chief researcher Ikuko Hara-Nishimura.

"A larger number means there are more intake windows for carbon dioxide, contributing to lowering the density of the gas," she said.

Black Carbon Deposits On Himalayan Ice Threaten Earth's 'Third Pole'

To better understand the role that black soot has on glaciers, researchers trekked high into the Himalayas to collect ice cores that contain a record of soot deposition that spans back to the 1950s. (Credit: Institute of Tibetan Plateau Research, Chinese Academy of Sciences)

From Science Daily:

Science Daily (Dec. 15, 2009) — Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities.

Why Humans Outlive Apes

Chimps and apes are genetically so similar to humans - and their human-like gestures do remind us how close we are on the family tree - that scientists have long been puzzled why they don't live as long as we do. Diet-related evolutionary changes may explain it. Image credit: stockexpert.

From Live Science:

Genetic changes that apparently allow humans to live longer than any other primate may be rooted in a more carnivorous diet.

These changes may also promote brain development and make us less vulnerable to diseases of aging, such as cancer, heart disease and dementia.

From Time Magazine:

Many Bordeaux winemakers are declaring 2009 the best vintage in 60 years, but Yvon Minvielle of Château Lagarette isn't celebrating. Like many vintners across France, Minvielle is feeling uneasy after another unusually warm summer and early grape harvest. "They say everything is going great in Bordeaux, but take a closer look," he says. Heat-stressed vines ripened at unequal rates this year, and only skillful picking spread over a full month allowed Minvielle to gather a mature crop.

Real Christmas Trees 'Greener' Than Fake


From Live Science:

It may not sound like "tree-hugging," but cutting down a real tree for Christmas is actually greener than going with the artificial kind, one scientist says.

"It is a little counterintuitive to people," said Clint Springer, a biologist at Saint Joseph's University in Philadelphia.

Because of concerns over deforestation around the world, many people naturally worry that buying a real tree might contribute to that problem, Springer says. But most Christmas trees for sale these days are grown not in the forest but on tree farms, for the express purpose of being cut.

Learning To Love To Hate Robots

Low expectations are easily surpassed (Image: Steve Olson/Getty)

From New Scientist:

ROBOTIC helpers are not yet in every home. But in recent years robots have steadily marched into the real world to perform tasks such as cleaning floors, delivering drugs or simply entertaining.

That has let anthropologists and roboticists give these mechanical workers their first report cards - and results are mixed. Despite evidence that we can find robots useful, even lovable colleagues, they can also trigger annoyance and violence. The results should help make future robots easier to work with.

Russia Reigns Over Its Weather

Snow may be an icon of Russian winters, but city officials in Moscow say it's too expensive to clear. They're considering a cloud-seeding process that would prevent heavy snowfalls in the capital. (Sergei L. Loiko / Los Angeles Times / December 8, 2009)

From The L.A. Times:

Moscow officials have already chased away clouds on public holidays. Now they're considering cloud seeding to keep snow-removal costs down in the winter. Neighboring towns may get dumped on.

Reporting from Moscow - In the snow-hushed woods on Moscow's northern edge, scientists are decades deep into research on bending the weather to their will. They've been at it since Soviet dictator Josef Stalin paused long enough in the throes of World War II to found an observatory dedicated to tampering with climatic inconveniences.
