WELSH scientists have been spearheading the hunt for alien life that may have fallen to Earth in a shower of "red rain".
Astrobiologists will today continue to examine traces of matter that poured its blood-red deluge over the Indian state of Kerala for two whole months in 2001.

London- The discovery of a Turkish family that walks on all fours could aid research into the evolution of humans.
Researchers believe the five brothers and sisters, who can walk naturally only on all fours, may provide new information on how humans evolved from four-legged hominids to walk upright.

The French government and MPs prepared to do battle Tuesday over a digital copyright bill that could clear the way for the legal downloading of music and movie files from the Internet.
Prime Minister Dominique de Villepin's centre-right government is trying to block MPs from voting to give such permission to Internet users, who would pay a small extra monthly fee to their Internet service provider for the right.

NASA is in the process of scripting how best to plant new bootprints on the Moon and take advantage of lunar resources that could prolong human stays on that barren ball of rock.
While the Moon is one desolate world, it could turn out to be a faraway faucet of sorts.
Robotic spacecraft--both the Pentagon's Clementine (1994) and NASA's Lunar Prospector (1998-1999) missions--point to the promise that the Moon is a literal watering hole for crews.
Permanently shadowed craters at the lunar poles, called "cold traps," might be repositories of water ice. More importantly, this reserve could be converted to oxygen, drinkable water, even rocket fuel.

On Monday, October 19, 1987 infamously known as "black Monday" the Dow fell 508 points, or 22.9%, marking the largest crash in history. Using an analytical approach similar to the one applied to explore heart rate, physicists have discovered some unusual events preceding the crash. These findings may help economists in risk analysis and in predicting inevitable future crashes.
Recent infrared observations made with NASA's Spitzer Space Telescope have revealed the presence of a huge intergalactic shock wave, or "sonic boom" in the middle of Stephan's Quintet, a group of galaxies which is now the scene of a gigantic cosmic cataclysm. This discovery, made by an international research team including scientists from the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, provides a local view of what might have been going on in the early universe, when vast mergers and collisions between galaxies were commonplace.
The arrangement of a mother's genes could affect the sexual orientation of her son, according to a new study.
The finding, detailed in the February issue of the journal Human Genetics, adds fuel to the decade-long debate about whether so-called "gay genes" might exist.
The researchers examined a phenomenon called "X chromosome inactivation" in 97 mothers of gay sons and 103 mothers whose sons were not gay.

Scientists have long wondered why organisms bother with sexual reproduction. It makes a whole lot more sense to just have a bunch of females that can clone themselves, which is how asexual reproduction works.
Turns out sex might have evolved as a way to concentrate lots of harmful mutations into individual organisms so they could be easily weeded out by natural selection, a new computer model suggests.

Women feel more pain than men, studies have shown. New research reveals one reason why.
Women have more nerve receptors, which causes them to feel pain more intensely than men, according to a report in the October issue of the journal Plastic and Reconstructive Surgery.
On average, women have 34 nerve fibers per square centimeter of facial skin. Men average just 17.

Scientists have discovered a huge crater in the Saharan desert, the largest one ever found there.
The crater is about 19 miles (31 kilometers) wide, more than twice as big as the next largest Saharan crater known. It utterly dwarfs Meteor Crater in Arizona, which is about three-fourths of a mile (1.2 kilometers) in diameter.
In fact, the newfound crater, in Egypt, was likely carved by a space rock that was itself roughly 0.75 miles wide in an event that would have been quite a shock, destroying everything for hundreds of miles. For comparison, the Chicxulub crater left by a dinosaur-killing asteroid 65 million years ago is estimated to be 100 to 150 miles (160 to 240 kilometers) wide.
