When most people think about water safety, they think about drinking water. That is important, of course. But human exposure ...

Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various ...

Measuring the results of scientific research has seen little federal focus until now. A 2010 administrative memorandum calls on U.S. federal agencies and executive departments to develop tools to ...

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 ...

Throughout any given year, the National Academies convene hundreds of conferences, workshops, symposia, forums, roundtables, and other gatherings that attract the finest minds in academia and the ...

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 ...

For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen ...

Scientists successfully measured an event using zeptoseconds, which is an incredibly brief fraction of a second. The time it took for a photo to pass through a hydrogen molecule was measured at 247 ...
