Sense of justice discovered in the brain

"Self interest is one important motive in every human," says Dr. Fehr , "but there are also fairness concerns in most people."

"In other words, this is the part of the brain dealing with morality," says Herb Gintis, an economist at the University of Massachusetts in Amherst, US. "[It] is involved in comparing the costs and benefits of the material in terms of its fairness. It represses the basic instincts."

Psychologist Laurie Santos, at Yale University in Connecticut, US, comments: "This form of spite is a bit of an evolutionary puzzle. There are few examples in the animal kingdom." The new finding is really exciting, Santos says, as the DLPFC brain area is expanded only in humans, and it could explain why this type of behaviour exists only in humans. -- NewScientist (Oct. 2006)

Предложен способ искать жизнь на отдаленных планетах

It is only a matter of time before astronomers find an Earth-sized planet orbiting a distant star. When they do, the first questions people will ask are: Is it habitable? And even more importantly, is there life present on it already?

Astronomers Lisa Kaltenegger of the Harvard-Smithsonian Center for Astrophysics (CfA) and Wesley Traub of NASA's Jet Propulsion Laboratory and CfA, propose using Earth's atmospheric history to understand other planets.

Earth's atmosphere has evolved through six distinct epochs, each characterized by a particular mix of gases. Kaltenegger and Traub modeled each of Earth's six epochs to determine what spectral fingerprints would be seen by a distant observer.
