Physicists are keen on solving the mysteries of the Earth’s magnetic field. Their curiosity has a practical side – when solar storms that create the aurora are bent by the magnetic field, it can affect technologies that modern civilization depends on.
A just-published study in Science Translational Medicine describes the success of a new kind of prosthesis, used by a Swedish truck driver for more than a year. The researchers say the device moves us one step closer to more natural control of artificial limbs.
Researchers at Sweden’s Uppsala University have developed a technique to extract the lithium from spent batteries and combine this with renewable biological material, to create a battery with a similar energy capacity to that of ordinary lithium-ion (Li-ion) batteries.
