Harvard researchers claimed last month that they had managed to create metallic hydrogen that has the capability to superconduct electricity at room temperature without resistance in a process that used massive amounts of pressure and a diamond vice. Stored at minus 193 degree celsius, the sample mysteriously disappeared, leaving researchers wonder whether it just evaporated. But they are determined to ...

Artificial eggs and sperm created in lab to help solve fertility problem

Using human embryonic stem cells, scientists for the first time have created primordial germ cells, which go on to become egg and sperm, in the lab to help answer problems related to fertility in the future. The pioneering results can help scientists provide answers to fertility problems, yield insight into the earliest stages of embryonic development and enable the development ...
