Worcester Polytechnic Institute Professor Nitin Sanket has secured a $704,908 NSF grant to develop sound-based navigation for tiny drones. His bio-inspired research, drawing from bats, will enable robots smaller than 100mm to operate in smoke, dust, and dark for search and rescue missions.

A COLDEX team led by U.S. scientists has discovered 6-million-year-old ice in Antarctica, the oldest directly dated on Earth. The ice from the Allan Hills reveals a 12-degree Celsius long-term cooling trend and offers an unprecedented window into the planet's warmer past, far exceeding researchers' initial expectations for the project.
