From Science Daily:

ScienceDaily (Apr. 8, 2009) — The design of efficient systems for splitting water into hydrogen and oxygen, driven by sunlight is among the most important challenges facing science today, underpinning the long term potential of hydrogen as a clean, sustainable fuel. But man-made systems that exist today are very inefficient and often require additional use of sacrificial chemical agents. In this context, it is important to establish new mechanisms by which water splitting can take place.

Now, a unique approach developed by Prof. David Milstein and colleagues of the Weizmann Institute’s Organic Chemistry Department, provides important steps in overcoming this challenge. During this work, the team demonstrated a new mode of bond generation between oxygen atoms and even defined the mechanism by which it takes place. In fact, it is the generation of oxygen gas by the formation of a bond between two oxygen atoms originating from water molecules that proves to be the bottleneck in the water splitting process. Their results have recently been published in Science.

France Moves To Crack Down On Internet Piracy

From New York Times:

BERLIN — French lawmakers are poised to approve a law to create the world’s first surveillance system for Internet piracy, one that would force Internet service providers in some cases to disconnect customers accused of making illegal downloads.

The proposal, called the “Création et Internet” and known informally as the “three strikes” directive, has been passed in preliminary votes by the Parliament and is expected to be approved in both houses Thursday. It has the support from the governing party of President Nicolas Sarkozy.

From Live Science:

For the first time, scientists have been able to “see” and trace lightning inside a plume of ash spewing from an actively erupting volcano.

When Alaska's Mount Redoubt volcano began rumbling back to life in January, a team of researchers scrambled to set up a system called a Lightning Mapping Array that would be able to peer through the dust and gas of any eruption that occurred to the lightning storm happening within. Lightning is known to flash in the tumultuous clouds belched out during volcanic eruptions.

The lightning produced when Redoubt finally erupted on March 22 was "prolific," said physicist Paul Krehbiel of New Mexico Tech.

AP Newsbreak: Obama Looks At Climate Engineering

A Regular Montreal Snowstorm

From Breitbart/AP:

WASHINGTON (AP) - The president's new science adviser said Wednesday that global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air.

John Holdren told The Associated Press in his first interview since being confirmed last month that the idea of geoengineering the climate is being discussed. One such extreme option includes shooting pollution particles into the upper atmosphere to reflect the sun's rays. Holdren said such an experimental measure would only be used as a last resort.

From New Scientist:

Chimpanzees trade precious scraps of meat for sex, new research shows. A two-year study of wild chimps finds that males boost their chances of having sex with a female by offering her meat.

But don't call them prostitutes. "It's not like 'I give you meat and a few hours later you're going to copulate with me,'" says Cristina Gomes, a primatologist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

She and colleague Christophe Boesch instead uncovered more nuanced and long-term exchanges.

From Technology Review:

A miniature telescope implanted into the eye could soon help people with vision loss from end-stage macular degeneration. Last week, an advisory panel for the Food and Drug Administration unanimously recommended that the agency approve the implant. Clinical trials of the device, which is about the size of a pencil eraser, suggest it can improve vision by about three and a half lines on an eye chart.

"This is one of the few options for people with end-stage macular degeneration," says Kathryn Colby, an eye surgeon at the Massachusetts Eye and Ear Infirmary, in Boston, who helped develop the surgical procedure used to implant the device.

Earthquake Predictions Remain Faulty at Best

1906 San Francisco Earthquake

From Live Science:

When it was revealed this week that Italian scientist Gioacchino Giuliani had predicted the earthquake in Italy but that he'd been ridiculed and muzzled, the hooey hairs stood up on the back of my neck.

I've been hearing stories about people who can predict earthquakes, using various methods from serious seismology to precursor headaches to watching their dog act strange, for years. And the bottom line remains the same:

It is not yet possible. In fact, it won't be for a long, long time.

From Science Daily:

ScienceDaily (Apr. 7, 2009) — In a step toward using gas hydrates as a future energy source, researchers in New York are reporting the first identification of an optimal temperature and pressure range for maximizing production of natural gas from the icy hydrate material.

Marco Castaldi, Yue Zhou, and Tuncel Yegualp note that gas hydrates, also known as "ice that burns," are a frozen form of natural gas (methane). This material exists in vast deposits beneath the ocean floor and Arctic permafrost in the United States and other areas. Scientists believe that fuel from these frozen chunks, formed at cold temperatures and high pressures, may help fuel cars, heat homes, and power factories in the future. Although scientists have identified several different methods for extracting the fuel, including depressurization, researchers have not found an practical approach for producing the gas on an industrial scale.

Listening To The Earth's Deepest Secrets

(Click the Above Image to Enlarge)

From New Scientist:

GARY ANDERSON was not around to see a backhoe tear up the buffalo grass at his ranch near Akron, Colorado. But he was watching a few weeks later when the technicians came to dump instruments and insulation into their 2-metre-deep hole.

What they left behind didn't look like much: an anonymous mound of dirt and, a few paces away, a spindly metal framework supporting a solar panel. All Anderson knew was that he was helping to host some kind of science experiment. It wouldn't be any trouble, he'd been told, and it wouldn't disturb the cattle. After a couple of years the people who installed it would come and take it away again.

Field Equations: The Physics of Baseball

From Scientific American:

A Q&A with physicist Alan Nathan.

At long last, Opening Day is nearly here. As with each new season, this one arrives with a slew of major-league questions: Can the Phillies repeat? Can the spendthrift Yankees break their World Series drought? Is this the year the Athletics reclaim their freewheeling magic? But the answers to all those big questions will ultimately arise from countless small interactions, both human (a pitcher facing down a batter, a base runner challenging a catcher's arm, a manager's clever double switch) and physical (a ball meeting the bat's sweet spot, a sharp slider slicing through the air, a pop fly tracing a parabolic arc through the sky).

Mt. Redoubt Eruptions – What Effect If Any On The Summer? Winter?

Mt. Redoubt March 26, 2009

From Watts Up With That:

Starting on March 22, a series of major eruptions have taken place from Mt. Redoubt in Alaska. The biggest exceeded 65,000 feet in height. More than a dozen eruptions as high as 60,000 have followed the first week alone. Activity may continue for weeks or months based on the volcano’s history.

Climatologists may disagree on how much the recent global warming is natural or manmade but there is general agreement that volcanism constitutes a wildcard in climate, producing significant global scale cooling for at least a few years following a major eruption. However, there are some interesting seasonal and regional variations of the effects.

From Science Daily:

ScienceDaily (Apr. 6, 2009) — Saturn's largest moon, Titan, may have a subterranean ocean of hydrocarbons and some topsy-turvy topography in which the summits of its mountains lie lower than its average surface elevation, according to new research.

Titan is also more squashed in its overall shape—like a rubber ball pressed down by a foot—than researchers had expected, said Howard Zebker, a Stanford geophysicist and electrical engineer involved in the work. The new findings may help explain the presence of large lakes of hydrocarbons at both of Titan's poles, which have been puzzling researchers since being discovered in 2007.

'I Predicted Killer Quake, But Officials Accused Me Of Scaremongering': Says Italian Seismologist

Seismologist Giacchino Giuliani predicted the earthquake which killed up to 100 people in L'Aquila just weeks before it struck

From The Daily Mail:

The Italian scientist who predicted a major earthquake which killed 90 people just weeks before disaster struck said authorities refused to take his claim seriously.

Seismologist Giacchino Giuliani said he was reported to authorities for spreading panic after the government claimed his research had no scientific foundation.

The 6.3-magnitude quake struck at around 2.30am UK time near L'Aquila.

The first tremors in the region were felt in mid-January and continued at regular intervals, creating mounting alarm in the medieval city, 60 miles east of Rome.
