Nadine Levin has been awarded a Post PhD Research Fieldwork Grant from the Wenner Gren Foundation for her project, “What is metabolism after big data? Health, bodies, and populations in the post-genomic sciences.“
Researchers at Caltech have discovered how an abundant class of RNA genes, called long non-coding RNAs (lncRNAs, pronounced link RNAs) can regulate key genes. By studying an important lncRNA, called Xist, the scientists identified how this RNA gathers a group of proteins and ultimately prevents women from having an extra functional X-chromosome–a condition in female embryos that leads to death…
Excerpt: “In March, a rumor surfaced in the scientific community that was intriguing, and perhaps a bit chilling: According to those in the know, researchers in China had successfully edited the genomes of human embryos, altering their DNA in a way never accomplished in our own species. MIT Technology Review reported on the murmurings that someone had altered the germ line —…
When scientists first made contact with an isolated village of Yanomami hunter-gatherers in the remote mountains of the Amazon jungle of Venezuela in 2009, they marveled at the chance to study the health of people who had never been exposed to Western medicine or diets. But much to their surprise, these Yanomami’s gut bacteria have already evolved a diverse array…
Scientists who study canine origins seem to fight about everything: where dogs arose, when this happened, and even the best way to find these answers. But there’s one thing most of them agree on: how dogs became domesticated. Still, it’s taken almost a century to get here, and the details are still emerging. So what did happen? Most experts now think dogs…
Studies of hunters and gatherers — and of chimpanzees, which are often used as stand-ins for human ancestors — have cast bigger, faster and more powerful males in the hunter role. Now, a 10-year study of chimpanzees in Senegal shows females playing an unexpectedly big role in hunting and males, surprisingly, letting smaller and weaker hunters keep their prey. The results do…
