Researchers found that female zebra finches inherit the disposition for infidelity from their fathers, who had also engaged in promiscuity. This genetic predisposition increases the likelihood of extra-pair matings, despite costs for females.
A new study found that the sex differences in the brains of songbirds vary according to their social status. Contrary to previous assumptions, dominant males' larger brain areas controlling song behaviour do not explain their dominance. Instead, gene activity and neural connections play a more significant role
Researchers have clarified an important step in the complex control circuit of insulin in the brain. Insulin inhibits nerve impulses, suppressing feelings of satiety and increasing energy expenditure, promoting overweight and obesity.
