From Mercury News:
A probe controlled from Ames Research Center that will hit the moon in two weeks may help unlock a major new scientific riddle, following NASA's stunning announcement Wednesday that the lunar surface is laced with water.
LCROSS (Lunar Crater Observation and Sensing Satellite), a mission controlled from Moffett Field in Mountain View, is scheduled to smash into a crater near the moon's south pole in the early hours of Oct. 9. Scientists will analyze the resulting debris plume for signs of large amounts of ice that may have persisted for eons in the extreme cold of perpetually shadowed craters.
The LCROSS mission had been about human exploration, trying to answer the question of whether there is enough ice on the moon to aid human exploration. The components of water — hydrogen and oxygen — could be used for life support or rocket fuel, if and when NASA returns astronauts to the moon.

How to Get Your Gadgets Off The Grid
From Popular Mechanics:
PM's October issue is all about how to survive disasters, including tales of off-the-grid homesteaders and stories of men who showed remarkable self-reliance in the face of hurricanes, blizzards and tornadoes. But surviving the aftermath of a major disaster without any electricity sounds pretty boring to PM senior technology editor Glenn Derene—what would he do without his LCD TV, wii, Internet access or power tools? In this “electric cold-beer gadget test,” Derene shows that with a small wind turbine, generator, solar charging kit and two very powerful batteries, you won’t have to abandon your gadgets (or beer fridge) after an emergency.

The World's Best Impact Craters
Also known as the "eye of Quebec", Manicougan Crater in Canada is one the Earth's oldest known impact craters, and is about 200 million years old. Today it contains a 70-kilometre hydroelectric reservoir along its edge. The island in the centre of the crater was formed by post-impact uplift of the land. Also visible in the bottom left-hand corner is the fin of the space shuttle from which this image was taken.(Image: LSTS-9 Crew/NASA/GSFC)
From The New Scientist:
Approximately 150 impact craters are known on Earth, but most are severely eroded or hidden beneath tonnes of rock. Still, a few spectacular examples are visible with aerial photography, satellites or instruments that can peek beneath the surface.

HIV Vaccine 'Reduces Infection'
From the BBC:
An experimental HIV vaccine has for the first time cut the risk of infection, researchers say.
The vaccine - a combination of two earlier experimental vaccines - was given to 16,000 people in Thailand, in the largest ever such vaccine trial.
Researchers found that it reduced by nearly a third the risk of contracting HIV, the virus that leads to Aids.
It has been hailed as a significant, scientific breakthrough, but a global vaccine is still some way off.

Mutations Make Evolution Irreversible: By Resurrecting Ancient Proteins, Researchers Find That Evolution Can Only Go Forward
Fish fossil. Researchers resurrected and manipulate the gene for a key hormone receptor as it existed in our earliest vertebrate ancestors more than 400 million years ago. Over a rapid period of time, five random mutations made subtle modifications in the protein's structure that were utterly incompatible with the receptor's primordial form. (Credit: iStockphoto)
From Science Daily:
A University of Oregon research team has found that evolution can never go backwards, because the paths to the genes once present in our ancestors are forever blocked. The findings -- the result of the first rigorous study of reverse evolution at the molecular level -- appear in the Sept. 24 issue of Nature.

Full Moon Does Not Affect Surgery Outcomes
From Live Science:
While a full moon can tug on ocean tides and make for a romantic setting, scientists have found no reliable evidence that it triggers suicides or hospital admissions, or facilitates conception, the transformation of werewolves or any of a host of other phenomena often blamed on it.
Evidence is mounting, however, for things on which the moon has no impact.

US Dirty Bomb Attack Would Bring Clean-Up Chaos
From New Scientist:
A dirty bomb attack on the US would find the country ill-prepared to clean up the resulting radioactive mess, a government watchdog has warned – and hasty attempts at cleaning up could make things worse.
Building a true nuclear bomb requires expert knowledge and possession of plutonium or enriched uranium, which governments keep under tight security. But more widely available radioactive materials, intended for applications such as medical imaging, could be used to construct a "dirty bomb" detonated a conventional explosives such as dynamite.
