Viewpoint: Reining in Alternative Gravity

Theorists have tightly constrained alternative theories of gravity using the recent joint detection of gravitational waves and light from a neutron star merger.

Device makes power conversion more efficient

New design could dramatically cut energy waste in electric vehicles, data centers, and the power grid. CAMBRIDGE, Mass. — Power electronics, which do things like modify voltages or convert between direct…

Hot spot at Hawaii? Not so fast

Rice University scientists’ model shows global mantle plumes don’t move as quickly as thought HOUSTON – Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like…

Researchers clarify mystery about proposed battery material

Study explains conflicting results from other experiments, may lead to batteries with more energy per pound. CAMBRIDGE, Mass. — Battery researchers agree that one of the most promising possibilities for…

UW helps create the largest neutrino detectors in the world

A new era in neutrino physics in the United States is underway, and UW–Madison’s Physical Sciences Laboratory (PSL) in Stoughton is playing a key role. The Long-Baseline Neutrino Facility, home to the $2…

Thin photodetector could increase performance without adding bulk

In today’s increasingly powerful electronics, tiny materials are a must as manufacturers seek to increase performance without adding bulk. Smaller also is better for optoelectronic devices — like camera sensors…

New method allows real-time monitoring of irradiated materials

Technique will enable continuous measurement of damage to materials in high-radiation environments. CAMBRIDGE, Mass. — A new advance on a method developed by MIT researchers could enable continuous, high-precision monitoring…

Unpolarized single-photon generation with true randomness from diamond

The Tohoku University research group of Professor Keiichi Edamatsu and Postdoctoral fellow Naofumi Abe has demonstrated dynamically and statically unpolarized single-photon generation using diamond. This result is expected to play…

OLYMPUS experiment sheds light on structure of protons

Seven-year study indicates two photons, not one, are exchanged in electron-proton interactions. CAMBRIDGE, Mass. — A mystery concerning the structure of protons is a step closer to being solved, thanks to…

Stars align in test supporting “spooky action at a distance”

Physicists address loophole in tests of Bell’s inequality, using 600-year-old starlight. CAMBRIDGE, MA — Quantum entanglement may appear to be closer to science fiction than anything in our physical reality….
