Scientists to Set Astronauts Moon Health Standards

The alien and perilous dust on the moon has prompted scientists to ponder lunar health standards that would be set before astronauts go there again.

A diverse team that includes flight surgeons, industry air quality experts, toxicologists, lunar geologists, and even an astronaut is examining how harmful lunar dust could be to humans.

A NASA scientist has a practical idea for building a telescope on the moon. Rather than flying one there, use the lunar soil to make one on site.

We may all be space aliens: study

Genetic material from outer space found in a meteorite in Australia may well have played a key role in the origin of life on Earth, according to a study to be published Sunday.

Flashback Did Life Begin In Space? New Evidence From Comets; Author responds to criticisms

Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists.

U.S. detector sniffs out biological, chemical threats

WASHINGTON - A new kind of mass spectrometer can sniff out biological, chemical and nuclear threats, all at virtually the same time, U.S. government researchers said on Thursday.

Their process, called Single-Particle Aerosol Mass Spectrometry, also detected illicit drugs and explosives without being reset in between tests, they said.

The team at the Department of Energy's Lawrence Livermore National Laboratory in California reported on their experiments in the journal Analytical Chemistry.

Noise Silenced By Acoustic Cloak

Researchers in Spain have proven that metamaterials, materials defined by their unusual man-made cellular structure, can be designed to produce an acoustic cloak -- a cloak that can make objects impervious to sound waves, literally diverting sound waves around an object.

Physicists Produce Quantum-entangled Images

Using a convenient and flexible method for creating twin light beams, researchers at the Joint Quantum Institute (JQI) of the Commerce Department's National Institute of Standards and Technology (NIST) and the University of Maryland have produced "quantum images," pairs of information-rich visual patterns whose features are "entangled," or inextricably linked by the laws of quantum physics.

In this photo montage of actual quantum images, two laser beams coming from the bright glare in the distance transmit images of a cat-like face at two slightly different frequencies (represented by the orange and the purple colors). The twisted lines indicate that the seemingly random changes or fluctuations that occur over time in any part of the orange image are strongly interconnected or "entangled" with the fluctuations of the corresponding part in the purple image. Though false color has been added to the cats' faces, they are otherwise actual images obtained in the experiment.

Sun goes longer than normal without producing sunspots

BOZEMAN -- The sun has been laying low for the past couple of years, producing no sunspots and giving a break to satellites.

Periods of inactivity are normal for the sun, but this period has gone on longer than usual.

Plasma-propelled Flying Saucer

Flying saucers may soon be more fact than mere science fiction. University of Florida mechanical and aerospace engineering associate professor Subrata Roy has submitted a patent application for a circular, spinning aircraft design reminiscent of the spaceships seen in countless Hollywood films. Roy, however, calls his design a "wingless electromagnetic air vehicle," or WEAV.

Weak evidence links congressmen's cyberattacks to China, experts say

IP address is not enough proof, they say

U.S. House members who say that China may have been responsible for attacks on their computers have provided little evidence to back up their claims, according to computer security experts.

The two Republican congressmen, Reps. Frank Wolf of Virginia and Christopher Smith of New Jersey,disclosed Wednesday that computers in their offices were hacked in late 2006 and early 2007. Both men have been critical of China's human rights record and said that the attacks raised concerns that they were being targeted for their support of Chinese dissidents.
