Researchers make promiscuous animals monogamous by manipulating genes

...relationships are involved in drug addiction. "The brain process of bonding with one's partner may be similar to becoming addicted to drugs: both activate reward circuits in the brain." The researchers' next step is to determine why there is extensive variability in behaviors among individuals within a sp...

Canine word-learning research published in Science

...dogs is remarkable. This ability suggests that the brain structures that support this kind of learning are not unique to humans, and may have formed the evolutionary basis of some of the advanced language abilities of humans," said Katrina Kelner, Science 's deputy editor for life sciences. The German tea...
