Single laser produces high-power dual comb femtosecond pulses

Researchers have developed a new approach that uses a single laser cavity to create two high-power optical frequency combs emitting high-power femtosecond pulses. The new development paves the way for portable dual-comb light ...

Evergreen needles act as air quality monitors

Every tree, even an evergreen, can be an air quality monitor. That's the conclusion of researchers at the University of Utah who measured the magnetism of particulate matter on the needles of evergreen trees on the U campus. ...

Researchers create better material for wearable biosensors

Biosensors that are wearable on human skin or safely used inside the body are increasingly prevalent for both medical applications and everyday health monitoring. Finding the right materials to bind the sensors together and ...

CRISPR a tool for conservation, not just gene editing

The gene-editing technology CRISPR has been used for a variety of agricultural and public health purposes—from growing disease-resistant crops to, more recently, a diagnostic test for the virus that causes COVID-19.
