Galaxy Blasts Neighbor with Deadly Jet
Topic: Science 9:42 am EST, Dec 18, 2007

For the first time astronomers have witnessed a supermassive black hole blasting its galactic neighbor with a deadly beam of energy.

The deadly galaxy — the largest of two in a system known as 3C321 — is aiming the high-energy jet from its center at a smaller galaxy 20,000 light-years away from it, or roughly the distance from Earth to the Milky Way's core. Both galaxies are situated about 1.4 billion light-years away from Earth.

South Korean scientists clone cats that glow in the dark.
Topic: Science 3:07 pm EST, Dec 13, 2007

South Korean scientists have cloned cats by manipulating a fluorescent protein gene, a procedure which could help develop treatments for human genetic diseases, officials said Wednesday. In a side-effect, the cloned cats glow in the dark when exposed to ultraviolet beams.

"The ability to produce cloned cats with the manipulated genes is significant as it could be used for developing treatments for genetic diseases and for reproducing model (cloned) animals suffering from the same diseases as humans," it added. The technology can also help clone endangered animals like tigers, leopards, and wildcats, Kong said.

Incredible Comet Bigger than the Sun

A comet that has delighted backyard astronomers in recent weeks after an unexpected eruption has now grown larger than the sun.

The sun remains by far the most massive object in the solar system, with an extended influence of particles that reaches all the planets. But the comparatively tiny Comet Holmes has released so much gas and dust that its extended atmosphere, or coma, is larger than the diameter of the sun.

Carbon Dioxide Levels Rising Much Faster Than Expected
Topic: Science 11:22 am EDT, Oct 23, 2007

Carbon dioxide levels in the atmosphere are increasing much faster and will be harder to control than scientists have predicted, a study has found. An international team of researchers has found that, since 2000, the rate at which CO2 has been pumped into the atmosphere is 35 percent greater than most climate-change models have allowed for. The conclusions have serious implications for forecasts of how much and how quickly the world's temperature will rise and mean that global warming will be harder and more expensive to control than feared.

Cooking Meat At High Temperatures Produces Estrogenic Effect

Troubling Meaty 'Estrogen'
by Janet Raloff
Science News Online

High temperature cooking can imbue meats with a chemical that acts like a hormone. Women take note. Researchers find that a chemical that forms in overcooked meat, especially charred portions, is a potent mimic of estrogen, the primary female sex hormone. That's anything but appetizing, since studies have linked a higher lifetime cumulative exposure to estrogen in women with an elevated risk of breast cancer.

Indeed, the new finding offers a "biologically plausible" explanation for why diets rich in red meats might elevate breast-cancer risk, notes Nigel J. Gooderham of Imperial College London. Overall, women who ate the most red meat—typically 1.5 servings or more per day—faced nearly double the invasive breast-cancer risk of those eating little red meat each week.

Gore Gets A Cold Shoulder
Topic: Science 9:55 am EDT, Oct 15, 2007

One of the world's foremost meteorologists has called the theory that helped Al Gore share the Nobel Peace Prize "ridiculous" and the product of "people who don't understand how the atmosphere works." Dr William Gray, a pioneer in the science of seasonal hurricane forecasts, told a packed lecture hall at the University of North Carolina that humans were not responsible for the warming of the Earth.

"The human impact on the atmosphere is simply too small to have a major effect on global temperatures," Dr Gray said. He said his beliefs had made him an outsider in popular science. "It bothers me that my fellow scientists are not speaking out against something they know is wrong," he said. "But they also know that they'd never get any grants if they spoke out. I don't care about grants."

Man With Almost No Brain Has Led Normal Life
Topic: Science 10:06 am EDT, Jul 25, 2007

French doctors are amazed that a 44-year-old civil servant with an abnormally small brain has led a normal life with a slightly lower than normal IQ, according to a report on Doctors said the father of two went to the Hopital de la Timone in Marseille with mild weakness in his left leg. He was given a CT scan and an MRI, which showed that his cerebral cavities or ventricles had massively expanded, according a case history to be published in Saturday's Lancet.

"The brain itself, meaning the grey matter and white matter, was completely crushed against the sides of the skull," Dr. Lionel Feuillet told AFP. "The images were most unusual... the brain was virtually absent." The condition is called Dandy Walker complex and is a genetically sporadic disorder that occurs in one out of every 25,000 live births, mostly in females. Although many with Dandy Walker develop dramatic symptoms from the condition, such as an enlarged skull, jerky muscle movements and problems with the nerves that control the face, the condition also can develop unnoticed.

Doctors believe this man's condition could stem from surgery he had at the age of 6 months, when he suffered hydrocephalus or water on the brain and needed an operation to drain a buildup of spinal fluid. Subsequent tests have revealed that the man has an IQ of 75, with a verbal IQ of 84 and performance IQ of 70. The bulk of people in society have a minimum IQ of 85.

Iraq war veteran Sgt. Juan Arredondo can grasp tennis balls and door knobs with his left hand again, now that he's been outfitted with a bionic hand that has flexible fingers. The 27-year-old former soldier, who lost his left hand in 2005 during a patrol, is one of the first recipients of the i-LIMB.
