A powerful genome editing tool may soon become even more powerful. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have unlocked the key to how bacteria are able to “steal” genetic information from viruses and other foreign invaders for use in their own immunological memory system. “We’ve shown that bacteria need only two proteins to facilitate this process, Cas1…
Last week, researchers expanded the size of the mouse brain by giving rodents a piece of human DNA. Now another team has topped that feat, pinpointing a human gene that not only grows the mouse brain but also gives it the distinctive folds found in primate brains. The work suggests that scientists are finally beginning to unravel some of the…
Patrick Allard, Assistant Professor with the Institute for Society and Genetics and the Department of Environmental Health Sciences, was awarded the prestigious 2015 International ToxScholar Award. Founded in 1961, the Society of Toxicology (SOT) is a professional and scholarly organization of more than 7,800 scientists from academic institutes, government, and industry representing the great variety of individuals who practice toxicology…
Vanessa Moreno knows what it’s like to feed a family on a tight budget. The fourth-year international development studies major watched her own mother, a single parent, do it when she was temporarily unemployed. Moreno is now chronicling on video the story of a single mother of five as she struggles to meet the same challenge. Fellow UCLA senior Sanna…
The difference between humans and their closest relatives is partly a matter of taste. Yams, pumpkins, and squash are as bland as potatoes to our tongues today, but to a chimp and our ancestors, wild varieties were bitter and yucky. Now scientists have pinpointed some of the genetic changes that allowed our ancestors to diversify their palates, potentially allowing them…
Fifteen chemicals that disrupt our endocrine hormonal systems have been linked to earlier menopause among US women. Amber Cooper from Washington University in St Louis, US, and colleagues found women aged 45 to 55 exposed to the organic compounds were up to six times more likely to be menopausal than unexposed peers. The substances include long-banned but persistent polychlorinated biphenyls…
