New quantum cascade lasers emit more light than heat

Northwestern University researchers have developed compact, mid-infrared laser diodes that generate more light than heat - a breakthroughs in quantum cascade laser efficiency.

Who is vulnerable to the impacts of tropical cyclones and why?

Tropical cyclones, and the torrential rains and strong winds these storms bring along with them, threaten coastal communities around the world and are expected to increase in intensity due to climate change. But not every ...

First detection of rain over the ocean by navigation satellites

In order to analyse climate change or provide information on natural hazards, for example, it is important for researchers to gather knowledge about rain. Better knowledge of precipitation and its distribution could, for ...
