China Plans World's Largest Solar Power Plant

First Solar: Here the company installs a 2 megawatt solar plant in California. Up next, one that's one thousand times the wattage, in China. First Solar

From Popular Science:

First Solar just signed an agreement with China to build the biggest solar power plant yet, according to a statement released today by the company. The 2-gigawatt plant in the Mongolian desert will generate enough electricity to power three million homes.

That's a heck of a lot of cadmium telluride, the semiconductor they use for their thin film cells.

The largest solar plant currently in operation is a mere 60-megawatt plant in Spain, according to pvresources.com.

Buzz Aldrin to NASA: U.S. Space Policy Is on the Wrong Track

Platon photographed Buzz Aldrin for PM in Los Angeles, May 2009. “It’s mankind’s destiny to walk on another planet,” Aldrin says. “We can achieve it, but we’ve got to have the right plan.” (Photograph by Platon)

From Popular Mechanics:

Apollo 11 astronaut Buzz Aldrin has a problem with NASA’s current manned space plan: Namely, the five-year gap between the shuttle’s scheduled retirement next year and the debut of the Ares I rocket and the Orion spacecraft, which will take us no further than the moon—a place we’ve already been. Aldrin thinks NASA can do better. His plan is to scrap Ares I, stretch out the remaining six shuttle flights and fast-track the Orion to fly on a Delta IV or Atlas V. Then, set our sites on colonizing Mars. Here, Buzz challenges NASA to take on his bolder mission.

From Live Science:

Houseplants can neutralize harmful ozone, making indoor air cleaner, according to a new study.

Ozone, which is the main component of smog, forms when high-energy light, such as the ultraviolet light from the sun, breaks oxygen bonds, ultimately resulting in O3, three atoms of oxygen joining together. When formed higher up in the atmosphere, the ozone layer protects us from harmful UV rays. Ground-level ozone is not so pleasant.

Ancient 'Smell Of Death' Revealed

Dying stinks, even for woodlice

From The BBC:

When animals die, their corpses exude a particular "stench of death" which repels their living relatives, scientists have discovered.

Corpses of animals as distantly related as insects and crustaceans all produce the same stench, caused by a blend of simple fatty acids.

The smell helps living animals avoid others that have succumbed to disease or places where predators lurk.

This 'death recognition system' likely evolved over 400 million years ago.

The discovery was made by a team of researchers based at McMaster University, near Hamilton, Ontario, Canada, and is published in the journal Evolutionary Biology.

"Quantum Quest" Brings Cassini to the Big Screen (Starring William Shatner as Every Star in the Universe)

From Popular Science:

Harry Kloor may be the world’s most well-rounded nerd. He is the only person to have earned doctorates in physics and chemistry simultaneously, and he has penned episodes of Star Trek: Voyager. And when NASA asked him for help in improving its image with young people, he drew on both of those experiences. The best way to get kids enthused about outer space, Kloor figured, was to hide their medicine in a bucket of popcorn. Next February, Quantum Quest, a star-studded CGI space adventure that pairs animated protons with real footage from NASA spacecraft, hits theaters. “Many of NASA’s scientists were inspired by Star Trek and Star Wars,” he says. “I want to inspire that kind of passion.” We caught up with Kloor to find out why kids will go nuts for quarks.

ScienceDaily (Sep. 7, 2009) — Eat less, exercise more. Now there is new evidence to support adding another "must" to the weight-loss mantra: eat at the right time of day.

A Northwestern University study has found that eating at irregular times -- the equivalent of the middle of the night for humans, when the body wants to sleep -- influences weight gain. The regulation of energy by the body's circadian rhythms may play a significant role. The study is the first causal evidence linking meal timing and increased weight gain.

Clues To Blast-Related Brain Injury

Credit: David Moore et al.

From Technology Review:

New research shows that explosions trigger unique damage to brain tissue.

The blasts caused by improvised explosive devices in Iraq and Afghanistan appear to inflict a fundamentally different type of brain damage than do more traditional sources of concussions, such as blunt trauma. The findings point toward new approaches to diagnosing and monitoring these injuries, which have been a huge concern to the military in recent years. The research also begins to resolve a controversy in brain-injury research--whether soldiers who are near an explosion but don't get hit in the head can still suffer a unique type of brain damage.

The new roll-to-roll nanoimprint lithography system could be used to cheaply and efficiently churn out nano-patterned optical films to improve the performance of displays and solar cells.

Nanoimprint lithography uses mechanical force to press out a nanoscale pattern and can make much smaller features than optical lithography, which is reaching its physical limits. The technique was developed as a tool for miniaturizing integrated circuits, and a handful of companies, including Molecular Imprints of Austin, TX, are still developing it for this application.

In medieval Europe, Jews were blamed so often, and so viciously, that it is surprising it was not called the Jewish Death. During the pandemic’s peak in Europe, from 1348 to 1351, more than 200 Jewish communities were wiped out, their inhabitants accused of spreading contagion or poisoning wells.

The swine flu outbreak of 2009 has been nowhere near as virulent, and neither has the reaction. But, as in pandemics throughout history, someone got the blame — at first Mexico, with attacks on Mexicans in other countries and calls from American politicians to close the border.
