Researchers have found that the irregular movement of lithium ions in next-generation battery materials could be reducing their capacity and hindering their performance. The team, led by the tracked the movement of lithium ions inside a promising new battery material in real time.

An international team of researchers has revealed new evidence for the possible existence of liquid water beneath the south polar ice cap of Mars. The researchers used spacecraft laser-altimeter measurements of the shape of the upper surface of the ice cap to identify subtle patterns in its height. They then showed that these patterns match computer model predictions for how a body of water beneath the ice cap would affect the surface.

Engineers have created intelligent 3D printers that can quickly detect and correct errors, even in previously unseen designs, or unfamiliar materials like ketchup and mayonnaise, by learning from the experiences of other machines.
