Stacking and twisting graphene unlocks a rare form of magnetism
7dSince the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the strongest, thinnest material known to man, it is also an excellent conductor of heat and electricity.
To protect nature's benefits, focus on people
7dTo calculate the true value of a forest, we need to know how people benefit from it, according to new research published in Nature Sustainability. A healthy forest holds a treasure trove of benefits for people—it can filter water for downstream communities, supply timber for building, and provide a place for people to connect with nature. But a forest—or any other ecosystem—won't necessarily provi
MHz, multi-beams coherent XUV source by intracavity high-order harmonic generation

New Clues to Chemical Origins of Metabolism at Dawn of Life
7dPopular speculations about how life evolved out of a soup of chemicals on the early Earth often focus on the origins of DNA and RNA , the molecules of genetic information. But the genesis of genes is only one of the mysteries that origin-of-life theories must reckon with. Another is the rise of metabolism — the biochemical processes inside cells that make life possible by continuously drawing ene
