From The Guardian:

Climate modeller Andrew Weaver launches libel action in Canada for publishing 'grossly irresponsible falsehoods'.

One of the world's leading climate scientists has launched a libel lawsuit against a Canadian newspaper for publishing articles that he says "poison" the debate on global warming.

In a case with potentially huge consequences for online publishers, lawyers acting for Andrew Weaver, a climate modeller at the University of Victoria, Canada, have demanded the National Post removes the articles not only from its own websites, but also from the numerous blogs and sites where they were reposted.

IPad’s Rivals Are On The March

From Times Online:

As Apple prepares to unleash the iPad in Britain, its rivals are preparing their fightback, rushing to create and release their own tablet computers, devices already dubbed the “iPad killers”.

Moreover, the attack on the iPad is coming on several fronts. The mobile phone maker Nokia is believed to be planning a similar machine designed mainly to read electronic books. Microsoft is flirting with the idea of creating a tablet. Even Google could enter the fray with a slate of its own.

Obama’s NASA Blueprint Is Challenged In Congress

From The New York Times:

WASHINGTON — President Obama may have hoped that a speech a week ago at the Kennedy Space Center would sway skeptics to his proposed space policy, but a Congressional hearing on Thursday gave little signs that the lines of contention have shifted yet.

Opponents like Richard C. Shelby, the Republican senator from Alabama where NASA’s Marshall Space Flight Center has been leading the design of the Ares I rocket that the Obama administration would like to cancel, continued to denounce Mr. Obama’s plans. Those plans call for ending NASA’s current Constellation program that was to send astronauts back to the moon and turning to private companies for transportation into orbit.

Maxed Out: How Long Can You Go Without Sleep?

Randy Gardner went without sleep for 11 days (Image: Don Cravens/Getty)

From New Scientist:

On 28 December 1963, Randy Gardner, a 17-year-old schoolboy in San Diego, California, got up at 6 am feeling wide awake and raring to go. He didn't go back to sleep again until the morning of 8 January 1964. That's 11 days without sleep.

Gardner's 264 hours remains the longest scientifically verified period without sleep, breaking the previous record of 260 hours. It was described in a 1965 paper by sleep researcher William Dement of the Stanford University School of Medicine in California, who stayed awake with Gardner for the final three days.

Diving Deep Into A Solar Prominence (SDO First Light)

April 21, 2010 -- What you're seeing here is the highest resolution photograph of the sun available to date, part of a brand new series of NASA Solar Dynamics Observatory (SDO) observations. The SDO mission promises "10 times better clarity than a high-definition television," NASA says, and this first SDO image doesn't disappoint.

From Discovery News:

Taken from a series of movies of bubbling plasma erupting to the solar surface, this is a close-up shot of what's called an expanding solar prominence, seen in extreme ultraviolet light. We are basically looking deep into the throat of the fine structure of an eruption on our nearest star.

The light we are seeing in this observation is generated by plasma heated to around 50,000 Kelvin (twice as hot as a bolt of lightning). A solar prominence is a looped structure of hot plasma, wrapped in magnetic fields from the sun's "surface" (or the photosphere), projecting high into the solar atmosphere (the sun's corona). But this is only one of the many eyes of SDO; it is already revolutionizing our understanding of the sun.

Magnesium Power: White-Hot Energy

From The Economist:

New power sources could be made using magnesium.

STORING energy is one of the biggest obstacles to the widespread adoption of alternative sources of power. Batteries can be bulky and slow to charge. Hydrogen, which can be made electrolytically from water and used to power fuel cells, is difficult to handle. But there may be an alternative: magnesium. As school chemistry lessons show, metallic magnesium is highly reactive and stores a lot of energy. Even a small amount of magnesium ribbon burns in a flame with a satisfying white heat. Researchers are now devising ways to extract energy from magnesium in a more controlled fashion.

The Air Force 'Baby Space Shuttle,' Secret And Reusable

From ABC News:

The Air Force’s “baby space shuttle” is ready for launch Thursday night from a launch pad at Cape Canaveral. The X-37B looks like a smaller version of the shuttle, and will be America’s second re-usable spacecraft, except it’ll be run by the military and be piloted by remote control. The 29 foot-long craft is designed to stay in orbit as long as 270 days (9 months) and it carries a secret payload of experiments.

"Secret" is the operative word. The Air Force isn’t saying how long it will be in orbit beyond saying that it won’t be a quick up-and-down test. It won’t describe what experiments will be aboard. They’re also touchy about media descriptions that it’s going to usher in the weaponization of space.

Maxed out: How Long Could You Survive Without Food Or Drink?

David Blaine went without food for 44 days (Image: Scott Barbour / Getty)

From New Scientist:

How long can a human survive without food or water? In theory, when you finally run out of body fat, protein and carbohydrates, your body runs out of energy and stops functioning. Jeremy Powell-Tuck, a retired clinician who fed David Blaine after his starvation stunt in London in 2003, isn't so sure that this is the lethal point. "You're more likely to die before then," he says. Fat people would only be able to survive for longer if they had enough vital water-soluble B vitamins in their system to help metabolise fat stores. So it is possible that a person could die of starvation and still be fat.

Why Aviation Industry Has Cloudy Knowledge Of Risks From Volcanic Ash

The Coming Tide of Global Climate Lawsuits

From Wired Science:

The Prunerov power station is the Czech Republic’s biggest polluter: Its Its 900-foot-high smokestack pushes a plume of white smoke high above the flat, featureless fields of northern Bohemia. Prunerov reliably wins a place on lists of Europe’s dirtiest power plants, emitting 11.1 million tons of carbon dioxide each year. So when CEZ Group, the state-controlled utility, proposed an overhaul to extend the facility’s life for another quarter of a century, protests flared — including one from a place about as far from the sooty industrial region as you can get, a place of tropical temperatures and turquoise seas with not a smokestack in sight. This January, the Federated States of Micronesia, some 8,000 miles away in the Pacific Ocean, lodged a legal challenge to the Prunerov plant on the grounds that its chronic pollution threatens the island nation’s existence.
