Water Found On The Moon

How So Much Water? Some Ideas...
A stream of charged hydrogen ions carried from the sun by the solar wind. One possible scenario to explain the new finding of water on the lunar surface is that during the daytime, when the moon is exposed to the solar wind, hydrogen ions liberate oxygen from lunar minerals to form OH and H2O, which are then weakly held to the surface. At high temperatures (red-yellow) more molecules are released than adsorbed. University of Maryland/F. Merlin/McREL

From Discovery News:

Shattering a long-held belief that Earth's moon is a dead and dry world, a trio of spacecraft uncovered clear evidence of water and hydrogen-oxygen molecules throughout the lunar surface.

"There's no question that there is OH [hydroxyl, which is made up of one hydrogen atom and one oxygen atom] and H2O on the moon," University of Maryland senior research scientist Jessica Sunshine told Discovery News.

India’s Lunar Mission Finds Evidence Of Water On The Moon

From The Independent:

Dreams of establishing a manned Moon base could become reality within two decades after India’s first lunar mission found evidence of large quantities of water on its surface.

Data from Chandrayaan-1 also suggests that water is still being formed on the Moon. Scientists said the breakthrough — to be announced by Nasa at a press conference today — would change the face of lunar exploration.

Satellite To Begin Gravity Quest

From The BBC:

A European spacecraft will begin its quest this week to make the most detailed global map of the Earth's gravity field.

The arrow-shaped Goce satellite can sense tiny variations in the planet's tug as it sweeps around the world at the very low altitude of just 255km.

The map will help scientists understand better how the oceans move.

It should also give them a universal reference to compare heights anywhere across the globe.

Wasted Space: U.S. Military Looking For Ideas On How To Curb The Threat Of Orbiting Junk

CLOUD OF CLUTTER: A visualization of the population of tracked objects, primarily debris, in low Earth orbit. The objects are not scaled with respect to Earth. NASA

From Scientific American:

DARPA is soliciting pitches on how best to remove orbital debris.

Gazing up into the sky on a clear night, the heavens can appear as pristine as a mountain stream. But in truth, at least in Earth's vicinity, the trash factor in space may be more akin to what is found in New York City's East River. The region known as low Earth orbit (extending from 160 to 2,000 kilometers above Earth's surface), which is where many satellites spend their lives and "afterlives," has a litter problem caused by decades of neglect, and it's one that currently lacks an expedient solution.

Drinking Alcohol May Make Head Injuries Less Harmful

Alcohol: Having a little alcohol in your blood could be a life-saver

From Popular Science:

Patients with alcohol in their blood are less likely to die from head injuries, according to a new study in Archives of Surgery, a JAMA/Archives journal.

The researchers found that the patients who tested positive for alcohol were less likely to die than patients who had no alcohol in their bloodstream. They were also generally younger and had less severe injuries. But patients who had drunk alcohol did suffer more medical complications during their stay in the hospital.

Asteroid Attack: Putting Earth's Defences To The Test

Are we prepared for an asteroid strike? (Image: Don Davis/NASA)

From The New Scientist:

IT LOOKS inconsequential enough, the faint little spot moving leisurely across the sky. The mountain-top telescope that just detected it is taking it very seriously, though. It is an asteroid, one never seen before. Rapid-survey telescopes discover thousands of asteroids every year, but there's something very particular about this one. The telescope's software decides to wake several human astronomers with a text message they hoped they would never receive. The asteroid is on a collision course with Earth. It is the size of a skyscraper and it's big enough to raze a city to the ground. Oh, and it will be here in three days.

From Science Daily:

Mathematicians from North America, Europe, Australia, and South America have resolved the first one trillion cases of an ancient mathematics problem. The advance was made possible by a clever technique for multiplying large numbers. The numbers involved are so enormous that if their digits were written out by hand they would stretch to the moon and back. The biggest challenge was that these numbers could not even fit into the main memory of the available computers, so the researchers had to make extensive use of the computers' hard drives.

From CNET:

PALO ALTO, Calif.--Baidu CEO Robin Li, on a rare visit to Silicon Valley Wednesday, explained the rise of his company's search engine in China before a group of students more interested in entrepreneurial tips than censorship.

Li ended a trip to the U.S. Wednesday at Stanford University, speaking to a crowd of several hundred students about the lessons he learned shepherding Baidu through the first dot-com bust and growing it into the Google of China. Baidu has 76 percent of the Chinese search market, he said, which consists of 338 million Internet users: larger than the entire population of the U.S.

Swine Flu Vaccine--Too Little, Too Late

Matt Collins

From Scientific American:

Long-standing liability issues leave us unprepared for a pandemic.

As health care workers in the U.S. gear up for the flu season, they facea paradox: on the one hand, they will have too little vaccine against the novel influenza A (H1N1) strain to protect the entire population; on the other, some people will resist the shots that are offered to them. Sadly, both problems can be traced, at least in part, to the last time “swine flu” loomed. The 1976 national vaccination campaign against a pandemic that never materialized left the public with lingering doubts about whether the inoculations harmed some recipients and spawned lawsuits that cost the federal government nearly $100 million.

Arctic Ice To Last Decades Longer Than Thought?

A polar bear navigates ice floes in Baffin Bay in the Canadian Arctic on July 10, 2008. This year's cooler summer means that the Arctic probably won't experience ice-free summers until 2030 or 2040, September 2009 research shows—but experts warn the cooling could be just a one-year reprieve.

From Science Daily:

Scientists have shown that the main shoot dominates a plant’s growth principally because it was there first, rather than due to its position at the top of the plant.

Collaborating teams from the University of York in the UK and the University of Calgary in Canada combined their expertise in molecular genetics and computational modelling to make a significant discovery that helps explain why pruning encourages plants to thrive.
