Structure of the human Polycomb Repressive Complex 2 (PRC2) bound to cofactors obtained by cryo-electron microscopy. Both cofactors mimic the histone protein tail to stabilize and stimulate the enzymatic activity of PRC2. (Credit: Vignesh Kasinath) All the …
This rendering shows a “ball-and-stick” representation of the atomic structure of a 2-D single crystalline layer of tungsten disulfide (blue and yellow) on top of layers of 2-D boron nitride (silver and gold). On top of these is a representation of the …
While there is a growing market for organic solar cells – they contain materials that are cheaper, more abundant, and more environmentally friendly than those used in typical solar panels – they also tend to be less efficient in converting sunlight to …

(Credit: iStock) Smart windows that are transparent when it’s dark or cool but automatically darken when the sun is too bright are increasingly popular energy-saving devices. But imagine that when the window is darkened, it simultaneously produces …
–By Laurie Chong Lithium-sulfur batteries are promising candidates for replacing common lithium-ion batteries in electric vehicles since they are cheaper, weigh less, and can store nearly double the energy for the same mass. However, lithium-sulfur …
Just as people can be left-handed or right-handed, scientists have observed chirality or “handedness” in swirling electric vortices in a layered material. (Credit: Pixabay) Scientists used spiraling X-rays at the Department of Energy’s Lawrence Berkeley …
Artist’s rendering of asteroids and space dust. (Credit: NASA/JPL-Caltech) Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system’s asteroid belt for billions of years, share something else in common: the …
Biocrust amongst one of its many natural habitats, taken about 20 miles from the sampling site (near the Corona Arch, Moab, UT). Credit: Tami Swenson Arid lands, which cover some 40 percent of the Earth’s terrestrial surface, are too dry to sustain much …
Artist’s illustration of two merging neutron stars. The rippling space-time grid represents gravitational waves that travel out from the collision, while the narrow beams show the bursts of gamma rays that are shot out just seconds after the gravitational …
For plants, light is great, until it’s not. They need the sun’s energy to carry out photosynthesis, but too much light damages the chloroplasts in plant cells where light, water, and carbon dioxide are converted into sugar and oxygen. One way plants …
This plot shows a thin slice through a mock galaxies catalog. The blue and green points are “bright” and “faint” galaxies simulated for the Dark Energy Spectroscopic Instrument’s Bright Galaxy Survey, and the red points show galaxies that are brighter than …

Berkeley Lab scientists are using powerful X-rays at the Advanced Light Source to study how gas mask filters handle chemical warfare agents. The work could eventually lead to more advanced gas masks for both military and civilian applications. (Video …

Stripes can be found everywhere, from zebras roaming in the wild to the latest fashion statement. In the world of microscopic physics, periodic stripe patterns can be formed by electrons within so-called quantum materials. Illustration of an ultrashort …
BERKELEY, CA / ARGONNE, IL – A team of Department of Energy (DOE) scientists at the Joint Center for Energy Storage Research (JCESR) has discovered the fastest magnesium-ion solid-state conductor, a major step towards making solid-state magnesium-ion …

IceCube has measured for the first time the probability that neutrinos are absorbed by Earth as a function of their energy and the amount of matter that they go through. This measurement of the neutrino cross section using Earth absorption has confirmed …
