How to rebuild an atomic clock
Atomic clocks are crucial for everyday living as they help our telecommunications, electrical power grids, GPS systems, transportation, and other processes around the world keep precise time. Some of these clocks use lasers and special resonator cavi.....»»
Low-cost sensor records the level of rivers
Researchers at the University of Bonn have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems. The study has been published.....»»
Young Ukrainians are throwing ‘repair raves’ to rebuild their embattled cities
DJs spin while grassroots activists work to clear rubble left behind by assaults from Russian forces. After more than 250 days of assaults from Russian forces, Ukrainian resistance is taking more surprising forms. In an attempt to reconnect to their.....»»

Magnetic quantum fluid: Extremely fluid in two ways
Two superfluids can exist at the same time in ultracold atomic clouds. Until now, their coexistence could not be observed experimentally. Now, however, physicists from Heidelberg University have demonstrated such a magnetic quantum fluid—it is flui.....»»
Artificial intelligence deciphers detector "clouds" to accelerate materials research
X-rays can be used like a superfast, atomic-resolution camera, and if researchers shoot a pair of X-ray pulses just moments apart, they get atomic-resolution snapshots of a system at two points in time. Comparing these snapshots shows how a material.....»»
