Light-emitting Electrochemical cells Lighting the way for a graphene-based future Linkoping University/Umea University/Rutgers University

From Popular Science:

New light-emitting electrochemical cells could replace OLEDs.

Graphene may brighten the future more literally than we had originally anticipated, besides merely revolutionizing electronics and Silicon Valley. Swedish and American researchers have transformed the one-atom-thick carbon material into a new, inexpensive lighting component that could give organic light diodes (OLEDs) a run for their money.

From The Telegraph:

New evidence that liquid water lies beneath the surface on the Saturn moonof Enceladus has been discovered by Nasa scientists, suggesting that life may exist.

Nasa's Cassini spacecraft flew through icy plumes created by ice volcanoes and detected negatively charged water molecules, in a clear sign an underground sea exists.

On Earth this short-lived type of ion is produced where water is moving, such as in waterfalls or crashing ocean waves.

Genetic Disorder Turns Risk-Averse Into Gamblers

From The Independent:

The brains of people who risk everything when gambling may be wired up differently to those of the naturally cautious, according to a study that appears to have discovered a neurological basis for reckless behaviour.

The research found that people were far more gullible to high-risk gambling when a small but distinct part of their brain had been damaged as a result of a rare genetic disorder. They showed little of the natural aversion to losing something of value that most people are born with.

His team found several chemicals on the inside of the cab of a half-pack-a-day smoker's truck, including a carcinogen called a NNK. Destaillats's team reckon that NNK is produced when nicotine from tobacco smoke reacts with nitrous acid in the air.

Will The Next Cold War Be In Cyberspace -- A Commentary

Two Futures Of The Internet: Next Cold War Or Up In The Clouds -- The Guardian

Will the future be cyber-attacks and an uneasy balance of terror or cultural collaboration hosted by Google's servers?

"THE FUTURE", WROTE the novelist William Gibson in a justifiably famous aphorism, "is already here: it's just not evenly distributed".

The challenge is to spot those uneven­ly distributed peeks into our future. The Apple iPad launch provoked a storm of peeking: optimists saw it as a sign that the computer industry had finally got the message that most people can't be bothered with the mysteries of operating systems and software updates and want an information appliance that "just works"; pessimists saw it as a glimpse into an authoritarian world dominated either by governments or a few powerful companies; sceptics saw it as just another product launch.

If you're struggling to improve your golf swing or strengthen your backhand, it may be that you are giving it too much thought.

A study shows that the masters of sport use less grey matter when in action than novices.

A group of good golfers were shown pictures of potential shots and asked how they would play them, undergoing brain scans as they responded. The process was repeated with poorer players.

With the better players, very little of the brain was lit up except for the areas that deal with choices and consequences.

Space Shuttle Blasts Off For Space Station

From The New York Times:

KENNEDY SPACE CENTER, Fla. — The space shuttle Endeavour thundered into orbit before dawn Monday morning, briefly turning darkness into daylight.

It was the second effort to get the Endeavour off the ground, 24 hours after clouds over the launching pad scrubbed Sunday’s attempt.

Clouds again encroached, but there were enough holes to allow the Endeavour to lift off on schedule at 4:14 a.m., a bright streak rising to the northeast along the East Coast. It was the 130th launching of a shuttle and probably the last night launching as the program winds down and ends after four more flights.

BEIJING -- A world without Google? They can imagine it just fine in China. After all, it's not like losing "World of Warcraft."

From FOX News:

If the U.S. won’t be going to the moon again anytime soon, who is?

Forty years ago the U.S. raced to plant the first foot on the moon. Now, as India, Russia, South Korea and China compete to return for further exploration, the U.S has all but dropped out -- and even Buzz Aldrin thinks that may be OK.

Aldrin, speaking to FoxNews.com, says the next step for NASA should be to create a long-term plan for more ambitious efforts -- visiting Mars or a nearby asteroid -- aided by robotics and astronauts from other countries. "It's much better to take our experience and aid other countries in conducting their races," says Aldrin.

Haiti's Environmental Aftermath

What the Jan. 12 earthquake means for the country's ecosystem.

The human toll of the Jan. 12 earthquake in Haiti has been devastating, with the government reporting more than 150,000 dead in the Port-au-Prince area alone. What, if anything, does the disaster mean for the environment?

It's a small solace, but the terrifying 7.0-magnitude earthquake seems not to have caused any major, immediate damage to Haiti's ecosystem. According to Asif Zaidi, operations manager of the U.N. Environmental Program's Post-Conflict and Disaster Management Branch, there has been one small spill near a coastal oil terminal, some minor warehouse fires, and a few small landslides close to Port-au-Prince, but nothing that requires a significant emergency response.

Beware Of Geoengineering Using Volcanoes' Tricks

From New Scientist:

WE HACK the climate at our peril. Volcanoes spewed so much sulphate into the atmosphere 94 million years ago that the oceans were starved of oxygen and 27 per cent of marine genera went extinct. Geoengineering our climate could inflict a similar fate on some lakes.

So claims Matthew Hurtgen at Northwestern University in Chicago, who with his colleagues measured sulphur isotopes in sediments on the floor of the Western Interior Seaway. The WIS was a vast body of water that divided the continent of North America down the middle at the time. The team also developed a model to simulate the impact of volcanoes on ocean chemistry.

How Sperm Swim: A Clue For Male Contraception?

From Time Magazine:

Though sperm are generally considered pretty wriggly little guys, before they are launched into action, so to speak, they aren't racing around. While researchers have long known that what gets them swimming is a change in internal pH level—the more alkaline their pH, the more aggressively they swim—until now, the mechanism by which sperm rapidly drop protons, which changes their pH from acidic to alkaline, wasn't clear. According to this new study, published in the journal Cell, sperm are equipped with tons of tiny little pores that, when open, enable them to release protons and get a move on.

From Science Daily:

ScienceDaily (Feb. 5, 2010) — MIT researchers have demonstrated the first laser built from germanium that can produce wavelengths of light useful for optical communication. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips. So the result could prove an important step toward computers that move data -- and maybe even perform calculations -- using light instead of electricity. But more fundamentally, the researchers have shown that, contrary to prior belief, a class of materials called indirect-band-gap semiconductors can yield practical lasers.
