The study of exoplanets — planets that lie outside our solar system — could help scientists answer big questions about our place in the universe, and whether life exists beyond Earth. But, these distant worlds are extremely faint and difficult to image directly.
NASA uses Earth as laboratory to study distant worlds
An active volcano has been unexpectedly discovered beneath a rapidly vanishing glacier in Antarctica by a team of scientists studying the melting ice shelf.

As silicon-based semiconductors reach their performance limits, gallium nitride (GaN) is becoming the next go-to material to advance light-emitting diode (LED) technologies, high-frequency transistors and photovoltaic devices. Holding GaN back, however, is its high numbers of defects.
The culprit of some GaN defects could be nitrogen
If bipedal robots are expected to successfully carry out intended tasks of search and rescue and disaster relief, then scientists and engineers will have to watch the robots' steps.
Bipedal robots ace dynamic walking on stepping stones
