More Pores Could Ease Global Warming

By boosting the number of pores in leaves, scientists hope to one day absorb more CO2 from the atmosphere. Credit: iStockphoto

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.

Real Christmas Trees 'Greener' Than Fake

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.

Russia Reigns Over Its Weather

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.

US And Russia In 'Secret' Cyber Warfare Talks -- The Telegraph

Russia and the United States are discussing how best to safeguard the internet against hostile attacks.

The talks, which are taking place between the US, Russia and a United Nations arms control committee, are aimed at finding ways of strengthening internet security and limiting the military use of cyberspace, according to a report in the New York Times.

Online attacks against government websites, corporate computer systems and other business-critical infrastructures have increased in the last two years. Anonymous hackers have managed to access the Pentagon's computers and overwhelm government websites, and President Obama has ordered an urgent review of the United States' internet security.

Apple’s Next Media Frontier Will Be Streaming Video

From Gadget Lab:

Video entertainment was “the one that got away” from Apple, but recent moves reveal the company is taking a second stab at the category, and that streaming video will play a major role.

The addition of video cameras to Apple’s latest iPhone and iPod Nano were just the first hints of the company’s new personal-media strategy. The company is also building a 500,000 square-foot data center in North Carolina, which could provide the massive bandwidth required for ubiquitous streaming video. And Apple’s recent acquisition of Lala suggests it’s interested in rebooting iTunes into a streaming service, according to Wall Street Journal. That means music, in Lala’s case, but the same infrastructure could be shared with streaming video.

Suzaku Catches Retreat Of A Black Hole's Disk

From Science Daily:

ScienceDaily (Dec. 12, 2009) — Studies of one of the galaxy's most active black-hole binaries reveal a dramatic change that will help scientists better understand how these systems expel fast-moving particle jets.

Binary systems where a normal star is paired with a black hole often produce large swings in X-ray emission and blast jets of gas at speeds exceeding one-third that of light. What fuels this activity is gas pulled from the normal star, which spirals toward the black hole and piles up in a dense accretion disk.

The opening riff of “Takin’ Care of Business” thumps rhythmically from an iPod as a room full of middle-aged military veterans tap in time on drums. This is the sound of brain rehab.

Studies show that music can promote new neural connections, which Colorado State University neuroscientist Michael Thaut theorized could help overcome common symptoms of traumatic brain injury (TBI), such as short-term memory loss and impaired decision-making skills. Thaut and his colleagues enrolled 31 veterans suffering from TBI in a “neurologic music therapy” study where each drummer matches rhythms and tempos set by a bandleader.

Piercing The Plasma: Ideas To Beat The Communications Blackout Of Reentry

HOT STUFF COMING THROUGH: Computer modeling by Krishnendu Sinha of the Indian Institute of Technology Bombay shows the heat flow a space capsule might generate during reentry. Hottest regions exceed 6,000 degrees Celsius (white, purple and red), coolest regions a few hundred (blue). Krishnendu Sinha Itt Bombay

From Scientific American:

Anticipating novel spacecraft and Mach 10 missiles, the U.S. Air Force considers new ways around an old problem.

The frustrating communications blackout that can occur when a spacecraft reenters the atmosphere caused some tense moments in the earlier years of the space age—perhaps most memorably during the crippled Apollo 13 mission. But the phenomenon could also affect communications with new aircraft and weapons systems being contemplated now by the U.S. Air Force, which hopes to find ways to pierce the blackout.
