From Scientific American:

The "new energy" economy rolls forward even as hopes for an international deal to combat climate change at Copenhagen shift into reverse.

BRIGHTON, Colo. - The low-carbon economy has already arrived on the windy prairie north of this fast-growing Denver 'burb. It's here that Danish wind-turbine giant Vestas converted 298 acres of hayfield into the West's largest turbine factory - and turned Brighton into a magnet for "green" energy companies.

It's part of a $1 billion investment by the company in the United States, what Colorado Gov. Bill Ritter touts as a "new energy economy."

Cocaine And Pepper Spray – A Lethal Mix?

Could be fatal (Image: Miguel Villagran/Getty)

From New Scientist:

DEATHS in US police custody during the early 1990s may have been the result of an interaction between capsaicin, the key ingredient in pepper sprays, and psychostimulant drugs, an experiment in mice suggests.

If the two have a fatal interaction in people then police forces might have to rethink their use of pepper spray as a non-lethal weapon, says John Mendelson of the Addiction and Pharmacology Research Laboratory at St Luke's Hospital in San Francisco, who led the mouse research.

How The Brain Hard-Wires Us To Love Google, Twitter, And Texting. And Why That's Dangerous.

From Slate:

Seeking. You can't stop doing it. Sometimes it feels as if the basic drives for food, sex, and sleep have been overridden by a new need for endless nuggets of electronic information. We are so insatiably curious that we gather data even if it gets us in trouble. Google searches are becoming a cause of mistrials as jurors, after hearing testimony, ignore judges' instructions and go look up facts for themselves. We search for information we don't even care about. Nina Shen Rastogi confessed in Double X, "My boyfriend has threatened to break up with me if I keep whipping out my iPhone to look up random facts about celebrities when we're out to dinner."

There Is More Water On The Moon Than What We Thought

Lunar Impactor Finds Clear Evidence Of Water Ice On Moon -- Wired Science

There is water on the moon, NASA confirmed today, and lots of it.

In the first look at results from the LCROSS mission, which sent a probe crashing into the Cabeus crater near the moon’s south pole, NASA’s main investigator said their instruments clearly detected water, despite the underwhelming plume.

Within the field of view of their instruments, the team measured approximately 220 pounds or about 26 gallons of water. Next, the team will try to understand how the compounds they saw in the plume relate to what’s actually embedded in the lunar regolith at the bottom of the permanently shadowed crater.

From Science News:

Scorpionflies may have aided plant reproduction long before blossoms evolved.

An obscure group of scorpionflies with specialized mouthparts may have pollinated ancient plants millions of years before flowers evolved, a new study suggests.

Fossils indicate that before flowers evolved about 130 million years ago, most plants with seeds were wind-pollinated. Yet the pollen grains of some plants that lived in the prefloral era were too big to be wind-dispersed, say Conrad Labandeira, a paleoentomologist at Smithsonian Institution’s National Museum of Natural History in Washington, D.C. Also, he notes, pollen receptors were hidden deep within some of those plants and wouldn’t have been readily exposed to windborne pollen.

From Science Daily:

Science Daily (Nov. 13, 2009) — When Europe's comet chaser Rosetta swings by Earth on Nov. 13 for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades.

Since 1990, scientists and mission controllers at ESA and NASA have noticed that their spacecraft sometimes experience a strange variation in the amount of orbital energy they exchange with Earth during planetary swingbys. The unexplained variation is noticed as a tiny difference in speed gained or lost during the swingby when comparing that predicted by fundamental physics and that actually measured after the event.

Behind The CDC's Soaring H1N1 Death Totals

From Time Magazine:

The Centers for Disease Control and Prevention (CDC) released on Thursday updated estimates of the number of H1N1 infections and deaths in the U.S. According to the new figures, about 4,000 Americans, including 540 children, have died of H1N1 flu, and 2 million people have been infected since April, when the novel flu virus first surfaced. The new death toll, which encompasses data through Oct. 17, represents a tripling of CDC estimates issued just last week; the number of deaths in children quadruples last week's figures. But the increase does not mean that the disease has suddenly become more deadly or severe, according to health officials, who say they are not surprised by the higher numbers.

From New Scientist:

NASA's twin Mars rovers have outlasted their planned three-month missions for so long that they seem indestructible. Nearly six years on, their presence on the Red Planet is taken for granted, as if they are immutable parts of the Martian landscape.

But we may soon have to confront a new reality. Spirit, which has always suffered more hardships than Opportunity, is facing its toughest challenge yet. When New Scientist went to press, the rover was set to begin a risky push to free itself from a sand trap it has been mired in for six months. Mission engineers say it may not survive the attempt. "She's in a very precarious situation, and we don't know for sure if we're going to get her out," says rover driver Scott Maxwell of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.

Wikipedia is under a censorship attack by a convicted murderer who is invoking Germany’s privacy laws in a bid to remove references to his killing of a Bavarian actor in 1990.

Lawyers for Wolfgang Werle, of Erding, Germany, sent a cease-and-desist letter (.pdf) demanding removal of Werle’s name from the Wikipedia entry on actor Walter Sedlmayr. The lawyers cite German court rulings that “have held that our client’s name and likeness cannot be used anymore in publication regarding Mr. Sedlmayr’s death.”

The Vatican Joins The Search For Alien Life

From The Telegraph:

The Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church.

The Pontifical Academy of Sciences is holding a conference on astrobiology, the study of life beyond Earth, with scientists and religious leaders gathering in Rome this week.

For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church: at least since Giordano Bruno, an Italian monk, was put to death by the Inquisition in 1600 for claiming that other worlds exist.

From CNET:

Painting the Golden Gate Bridge yellow might cause less fuss than trying to install a wind farm off Cape Cod's historic coast.

But when you're trying to build where the wind is strongest or the sun is brightest, you never know what obstacles you may run into.

In Massachusetts, a proposed wind farm called Cape Wind was dealt a blow last Friday that will delay what would be the first offshore wind farm in the U.S. The Massachusetts Historical Commission agreed with local Indian tribes who claim that the location for the wind farm should be considered for listing in the National Historic Register because the Wampanoags' history and culture are "inextricably linked to Nantucket Sound," according to the opinion.

From Science Daily:

Science Daily (Nov. 11, 2009) — Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond. These systems, which have not been simulated in detail until now, could in the future serve as a compact new technology for particle colliders and energetic light sources.
