From Live Science:

Comets have inspired both awe and alarm since antiquity, "hairy stars" resembling fiery swords that to many were omens of doom. Nowadays, scientists have found evidence that comets not only may have taken life away through cataclysmic impacts, they may have helped provide life by supplying Earth with vital molecules such as water — possibilities they hope to learn more about from the encounter with Comet Hartley 2 tomorrow (Nov. 4).

Scientists May Have Discovered A Cure For The Common Cold (And Lots Of Other Viruses)

Virus Attack! Virus (purple) circulating in the bloodstream recognised by antibodies (yellow) of the immune system The Independent

From Popular Science:

Any immunology textbook will tell you that once a virus enters a cell, the only way to knock that virus out is to kill the entire cell. But a new study from the Laboratory of Molecular Biology at Cambridge has shown a way to kill a virus from within the cell, leaving the virus defeated and the cell victorious and intact. This could be huge--not just a cure for the common cold, but for all kinds of other viruses as well.

From The Australian:

EVIDENCE has been found of a massive asteroid impact near the Queensland-South Australia border more than 300 million years ago.

The asteroid, which produced a shock zone at least 80km wide, could be the second-largest asteroid ever found in Australia.

The Other 'G' Spot

From Wall Street Journal:

At the beginning of the 20th century the British psychologist Charles Spearman "discovered" the idea of general intelligence. Spearman observed that students' grades in different subjects, and their scores on various tests, were all positively correlated. He then showed that this pattern could be explained mathematically by assuming that people vary in special abilities for the different tests as well as a single general ability—or "g"—that is used for all of them.

Technologies that analyze cancer cells that circulate through a patient's bloodstream could provide a less invasive way of monitoring cancer and selecting the best treatments. So Mehmet Toner and collaborators at Massachusetts General Hospital have developed a microfluidics chip that effectively captures these rare cells, which make up just one in a billion cells in blood, in high enough numbers to analyze them for molecular markers. The device also isolated clusters of tumor cells for the first time, which may help shed light on cancer's ability to spread, or metastasize, from its initial birthplace.

Signal Achievements In Army History (Photos)

In 1860, the man in the center of this photo, Albert Myer, became the first-ever signal officer of the U.S. Army. (He's seen here some months later during the Peninsula campaign of the Civil War.) While the government liked Myer's ideas on signaling well enough to establish the U.S. Army Signal Corps at that time, the early years of the undertaking faced any number of challenges--ungainly technology, bureaucratic infighting, lack of funding and staffing. But the seed was planted in those early days, and the Signal Corps has now been around for 150 years (making this year the sesquicentennial), at the forefront of technologies from the telegraph to radio, radar, and satellite communications.

Strong Magnets With Printed Poles Have Endless Engineering Applications

From Popular Mechanics:

The Brilliant Idea: Magnets printed with multiple poles, opening the door to myriad applications.

Larry Fullerton set out to invent a self-assembling magnetic toy that would fuel his grandchildren’s passion for science. Instead, he invented a way to manipulate magnetic fields that redefines one of the fundamental forces of nature.

Fullerton’s breakthrough tramples the long-held assumption that magnets have two opposing poles, one on each side. He found that if he used heat to erase a magnetic field, he could then reprogram material to have multiple north and south poles of differing strengths. “People look at magnets as having a north pole and a south pole. That limits your thinking,” he says. “I came along from the field of radar and said, ‘Hey, that’s not a magnet—it’s a vector field!’”

The Slippery Slope To Obesity

Not a good start (Image: Wade/Getty)

From New Scientist:

REWARD pathways in the brains of overweight people become less responsive as they gain weight. This causes them to eat more to get the same pleasure from their food, which in turn reduces the reward response still further.

Eric Stice, a psychologist at the University of Texas at Austin, and colleagues used fMRI brain scans to monitor 26 obese or overweight volunteers as they sipped either a tasty milkshake or a flavourless liquid resembling saliva. They compared the effect of both drinks on brain activity in the dorsal striatum, a key part of the brain's reward circuitry. Six months later, they retested the volunteers.
