A recent study showed that people who spend most of their days under some form of artificial light can reset their internal clocks to match the sun's cycle after only a week out in nature.
By altering genes that influence mosquitoes' response to odors, researchers at the Howard Hughes Medical Institute have created an insect that won't necessarily choose a human to sting first.
By not using actual embryos, scientists at two Oregon-based institutions sidestepped one of the largest issues surrounding stem cell technology. The breakthrough follows similar success with monkey skin cells in 2007.
Our power to manipulate our brains and genes is increasing dramatically – and it raises serious ethical questions.
