[:es] As the first clinical trial results trickle in, researchers look ahead to more sophisticated medical applications for genome editing. [:]

[:es]If any swine is fit to be an organ donor for people, then the dozens of pigs snuffling around Qihan Bio’s facility in Hangzhou, China, may be the best candidates so far. The Chinese company and its U.S. collaborators reported today that they have used the genome editor CRISPR to create the most extensively genetically…

[:es]More than 5700 years ago, a girl spat out a wad of chewing gum at what is now an archaeological site in Denmark. Today, researchers report in Nature Communications that they have sequenced a full genome from that gum, the first time they have extracted so much information from anything other than ancient bones or…

[:es] A promising field of research on social behaviour struggled after investigators couldn’t repeat key findings. Now researchers are trying to establish what’s worth saving. [:]

[:es]Many human grandmothers love to spoil their grandchildren with attention and treats, and for good reason: Studies have shown that having a living grandmother increases a child’s chance of survival. Now, new research shows the same may be true for killer whales. By providing young animals with some freshly caught salmon now and then—or perhaps…

[:es] Research suggests it’s more likely close-knit cliques. [:]

[:es]New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.[:]

[:es]Like vinyl records, the strange concept of a time crystal is spinning back into fashion. In 2012, a Nobel Prize–winning physicist proposed that the properties of a system of quantum particles might cycle in time much as a crystal’s pattern of atoms repeats in space, even without the addition of energy, making it a bit…

[:es]Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.[:]
