Resurrecting ancient proteins, team finds just two mutations set stage for evolution of modern hormone signaling
Evolution, it seems, sometimes jumps instead of crawls. A research team led by a University of Chicago scientist has discovered two key mutations that sparked a hormonal revolution 500 million years ago.
A laser beam's path through NASA's ICESat-2
Before beaming 300 miles to Earth's surface, bouncing off the ground and travelling another 300 miles back into space, the laser photons on NASA's Ice, Cloud and Land Elevation Satellite-2 first have to complete ...

Smarter programming of stoplights could improve efficiency of urban traffic
Sitting in traffic during rush hour is not just frustrating for drivers; it also adds unnecessary greenhouse gas emissions to the atmosphere.
Traffic monitoring to generate knowledge
Researchers at UPM have developed an application that generates traffic information for cities and roads by detecting a Bluetooth device boarded on vehicles.
Is truth stranger than fiction? Yes, especially for science fiction
From warp drives to hyperspace, science fiction has continuously borrowed from, and sometimes anticipated, the state of the art in scientific progress. This has resulted in the perception that science and ...
