Extreme black holes have hair that can be combed

Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually among the simplest solutions to Einstein's field equations of general relativity. ...

Researchers develop biodegradable printed display

In the next years, increasing use of electronic devices in consumables and new technologies for the internet of things will increase the amount of electronic scrap. To save resources and minimize waste volumes, an eco-friendlier ...

Metamaterial tiles boost sensitivity of large telescopes

A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated ...

A benchmark for single-electron circuits

Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, ...

Building a corn cob—cell by cell, gene by gene

Corn hasn't always been the sweet, juicy delight that we know today. And, without adapting to a rapidly changing climate, it is at risk of losing its place as a food staple. Putting together a plant is a genetic puzzle, with ...

LSD may offer viable treatment for certain mental disorders

Researchers from McGill University have discovered, for the first time, one of the possible mechanisms that contributes to the ability of lysergic acid diethylamide (LSD) to increase social interaction. The findings, which ...

Cell 'bones' mystery solved with supercomputers

Our cells are filled with 'bones,' in a sense. Thin, flexible protein strands called actin filaments help support and move around the bulk of the cells of eukaryotes, which includes all plants and animals. Always on the go, ...

Solar hydrogen: Photoanodes promise high efficiencies

Photoanodes made of metal oxides are considered to be a viable solution for the production of hydrogen with sunlight. α-SnWO4 has optimal electronic properties for photoelectrochemical water splitting with sunlight, but ...

Reef fish futures foretold

An international group of scientists is predicting markedly different outcomes for different species of coral reef fishes under climate change—and have made substantial progress on picking the 'winners and losers'.

Fighting racial inequity by funding Black scientists

Representatives from a network of women deans, chairs and distinguished faculty in biomedical engineering are calling upon the National Institutes of Health and other funding agencies to address disparities in allocating ...
