Psychologists have always puzzled over why people in Sweden were slower to start smoking and slower to stop. Now a group of mathematicians have worked out why.
If background levels of neutron radiation can explain errors in computer memory, then it should also explain errors in DNA replication.
Chinese biomedical engineers have used liquid metal to transmit electrical signals across the gap in severed sciatic nerves. The work raises the prospect of a new treatment for nerve injuries, they say.
By defocusing a microscope, biologists have developed a simple technique that produces three-dimensional images of red blood cells.
A low-cost microscope made from folded paper and a cheap lens could revolutionize education and health care in the developing world.
Physicists have developed a technique that can tell which parts of the brain rely on analog signals and which rely on digital signals.
A mathematical model of how to tackle Vicodin abuse reveals that Benjamin Franklin had the right idea 200 years ago
Increasing the rate at which we develop new drugs is a good way to tackle multidrug resistance. But there is another strategy that is inherently better, say researchers
Intelligent dust particles embedded in the brain could form an entirely new form of brain-machine interface, say engineers
