A previously detected, anomalously large X-ray signal is absent in new Hitomi satellite data, setting tighter limits for a dark matter interpretation.

How do scientists know what percentages of the universe are made up of dark matter and dark energy?

The Dark Energy Spectroscopic Instrument will measure light from 35 million cosmic objects for new insights into what causes the universe to expand faster and faster.

Silicon chips can store data in billionths of a second, but phase-change memory could be 1,000 times faster, while using less energy and requiring less space.

An interdisciplinary team has developed a way to track how particles charge and discharge at the nanoscale, an advance that will lead to better batteries for all sorts of mobile applications.

The scientists develop methods to study neutrinos from star explosions and search for unknown particles and forces with possible ties to dark matter.

The mirrors only differ by one atom in flatness, from end to end.

The White House announced $50 million in funding for ‘Battery500’, a five year effort, as part of a package of initiatives to accelerate adoption of electric vehicles in the U.S.

Scientists are using plasma to create electronic sensors that will track the health of astronauts.

The Standard Model is far more than elementary particles arranged in a table.
