In the mid-1990s, scientists at the University of Parma, in Italy, made a discovery so novel that it shifted the way psychologists discuss the brain.

After researchers implanted electrodes into the heads of monkeys, they noticed a burst of activity in the premotor cortex when the animals clutched a piece of food. In a wonderfully fictitious account of the discovery, neuroscientist Giacomo Rizzolatti was licking ice cream in the lab when this same region again fired in the monkeys. In an equally wonderful truthful account, the neurons in this region did, in fact, fire when the monkeys merely watched researchers handle food.

There seems to be something new under the sun -- in the sky, specifically -- that could complicate scientists' efforts to get a fix on how much the world will warm in the future. Greenhouse gases are not the only things in the air that influence the temperature of our atmosphere. Clouds and small airborne particles called aerosols also play an important and complicated role. And now a new ingredient has been discovered: an extensive and previously unseen "twilight zone" of particles that represents a gradual transition from cloud droplets to dry particles.

A team of Australian, American and French coral reef scientists has achieved a world breakthrough in tracking fish that could revolutionize the sustainable management of coral reefs and help restore threatened fisheries. Working on coral reefs in a marine protected area in Papua New Guinea, the team has pioneered a new way to study fish populations by "tagging" adult fish with a minute trace of a harmless isotope, which they pass on to their offspring.

Hamilton College researchers have identified molecules that have been shown to be effective in the fight against breast cancer.

The Hamilton researchers used state-of-the-art computational techniques in a novel way to design molecules that they predicted would be effective lead compounds for breast cancer research. Scientists from the Albany Medical College subsequently synthesized the predicted molecules and showed that they were indeed potential anti-breast cancer compounds in animal systems.

Preterm related deaths accounted for more than 10,000 of the nearly 28,000 infant deaths in 2004, according to the NCHS. Birth defects remain the leading cause of infant death, followed by prematurity, according to official reporting systems. But, using this new classification, premature birth would be the most frequent cause of infant death. The traditional methods cannot accurately gauge the true impact of preterm birth on the infant mortality rate, the NCHS said.

In adult monkeys, an antidepressant treatment has induced new nerve cell growth in the hippocampus, a brain area responsible for learning and memory. A similar process may occur in humans, the research suggests, and may help explain the effectiveness of antidepressant treatments.

Euthanasia for newborn babies with lethal and disabling conditions is illegal worldwide, but in reality, its acceptance and practice vary between different countries.

In the Netherlands, about 200,000 live births occur annually; of these, 10-20 babies – mostly with severe congenital malformations – are thought to be actively killed. Yet between 1997 and 2004 only 22 such deaths were reported to the authorities, writes Kate Costeloe, Professor of Paediatrics at the University of London.

COROT has provided its first image of a giant planet orbiting another star and the first bit of ‘seismic’ information on a far away, Sun-like star- with unexpected accuracy.

The unanticipated level of accuracy of this raw data shows that COROT will be able to see rocky planets - perhaps even as small as Earth - and possibly provide an indication of their chemical composition.

Astronaut Walter M. "Wally" Schirra Jr., one of the original Mercury Seven astronauts and the only man to fly on all three of NASA's early space missions, has died at the age of 84, a NASA official confirmed Thursday.

Schirra, who commanded the first rendezvous of two spacecraft in orbit, died of natural causes, according to NASA.

"We have spoken with his family and we can confirm he did die of natural causes.

As a group, young ADHD drivers are two to four times more likely to have a car accident than non-ADHD drivers. Daniel Cox, Ph.D., professor of psychiatry and neurosciences at the University of Virginia Health System, has conducted research aimed at improving those odds. His team's newest study will look at the effects of methylphenidate (MPH), a controlled-release stimulant, on young ADHD drivers facing real-life distractions.
