Are we genetically programmed to be generous?
Are those inclined towards generosity genetically programmed to behave that way? A team of researchers, including Dr. Ariel Knafo of the Psychology Department at the Hebrew University of Jerusalem, believes that this could very well be the case.
Attractiveness is it's own reward
Studies of the snap judgments we often make about people are shedding new light not only on social behavior, but also on drug abuse, gambling addiction, and other disorders in which our ability to make decisions is impaired, say scientists at the California Institute of Technology.

Humans appear hardwired to learn by over-imitation
Children learn by imitating adults—so much so that they will rethink how an object works if they observe an adult taking unnecessary steps when using that object, according to a Yale study today in Proceedings of the National Academy of Sciences.
Researchers discover cancer cells 'feel' much softer than normal cells
A multidisciplinary team of UCLA scientists was able to differentiate metastatic cancer cells from normal cells in patient samples using leading-edge nanotechnology that measures the cells' softness.
Discovery could help bring down price of dna sequencing
In May, Nobel Laureate James D. Watson, the scientist who co-discovered the structure of DNA, became the first person to receive his own complete personal genome -- all three billion base pairs of his DNA code sequenced. The cost was $1 million, and the process took two months.
Got sugar? Glucose affects our ability to resist temptation
New research from a lab at Florida State University reveals that self-control takes fuel-- literally. When we exercise it, resisting temptations to misbehave, our fuel tank is depleted, making subsequent efforts at self-control more difficult.
