The world’s leading candidate for a malaria vaccine has cleared another hoop on the way to widespread use, proponents say. But the vaccine’s low efficacy against severe forms of the disease have disappointed some experts.
The top ocean predators in the North Pacific could lose as much as 35% of their habitat by the end of the century as a result of climate change , according to a study published in the journal Nature Climate Change. The analysis took data compiled from tracking 4,300 open-ocean animals over a decade and…
John B. Gurdon of the U.K. and Shinya Yamanaka of Japan shared this year’s Nobel Prize in Physiology or Medicine for their work in so-called cellular reprogramming, which has unleashed a wave of advances in everything from cloning to the possible treatment of diseases using stem cells. The researchers’ experiments showed how specialized, mature cells…
In an unlikely marriage of quantum physics and neuroscience, tiny particles called quantum dots have been used to control brain cells for the first time. Having such control over the brain could one day provide a non-invasive treatment for conditions such as Alzheimer’s disease, depression and epilepsy. In the nearer term, quantum dots could be…
Pumice-like cratery indents formed by ancient raindrop splats are adding to the mystery of why the adolescent Earth was warm enough to host rivers and oceans, despite the dim sun of the day. Thanks to fossilized impressions from rains that fell down on Africa 2.7 billion years ago, the “Faint Young Sun” paradox is getting…
As family and friends of Neil Armstrong gathered in Ohio on Aug. 31 for a private memorial service, NASA paid tribute to the Apollo astronaut, calling him a great American and a space hero. “He never dwelled on his remarkable accomplishments or sought the limelight,” Kennedy Space Center director and former astronaut Robert Cabana said…
The relationship between humans and chimpanzees, thought to be pretty close in evolutionary terms, now comes down to a number: 510. Those are the genetic elements, in key areas of the genome, that differ between the two species. Surprisingly they aren’t 510 pieces of DNA that we have and chimps don’t. It’s actually the other…
