A new plastic “skin” can detect how hard it is being pressed and generate an electric signal to deliver sensory input directly to a living brain cell.

Every time you stroll outside you emit energy into the universe. Heat from the top of your head radiates into space as infrared light.

Scientists have reprogrammed the genetic machinery of baker’s yeast so that the fast-growing cells can convert sugar into hydrocodone in just three to five days.

Under certain circumstances, droplets of fluid will move like performers in a dance choreographed by molecular physics.

Researchers would like to place very small implants deep inside our bodies to monitor health or treat pain. But providing electric power to implants without wires or batteries has been a big obstacle.

A new radio the size of an ant can gather all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna—no batteries required.

Compared to the human brain, today’s computers are ridiculously slow and take about 40,000 times more power to run.

Researchers have created a novel way to do time-lapse studies of crystallization that could lead to more flexible and effective electronic displays, circuits, and pharmaceutical drugs.
