Engineers have developed a miniature, wireless, injectable biosensor that could be used for continuous, long-term alcohol monitoring. The chip is small enough to be implanted in the body just beneath the surface of the skin.
Scientists from Australia and China have used gold nanomaterials to demonstrate a new high-capacity optical disk able to hold data securely for more than 600 years, while using 1,000 times less power.
Researchers in Germany have achieved a new propulsion method for molecular machines, which enables them to be moved 100,000 times faster than biochemical processes used to date.
