"For asteroids of the size scale relevant to planetary defense (i.e., ∼50-500 m), the mass can only be directly measured ...

In a new paper for the Proceedings of the National Academy of Sciences, we, alongside colleagues from a diverse range of fields, investigate the prevalence and extent of censorship and self-censorship ...

A new report sponsored by the U.S. Department of Energy (DOE) recommends increased investment in America’s fusion diagnostic ...

Measuring the 'wettability' of graphene and other 2D materials. Microscopic understanding of wettability can be achieved at the molecular level using 'vibrational sum-frequency generation spectroscopy ...

They're all around us: sensors and satellites, radars and drones. These tools form vast remote sensing networks that collect data on the climate, the ground, the air, and the water. This information ...

Imagine trying to measure a tennis ball that bounces wildly, every time to a distance a million times its own size. The bouncing obviously creates enormous "background noise" that interferes with the ...

To really understand neutrons, physicists may have to take to space. When outside the confines of an atomic nucleus, a neutron decays into other particles in about 15 minutes on average. But exactly ...
