By Kate Kelland LONDON, Oct 5 (Reuters) - - Some 30 years after the world's worst nuclear accident blasted radiation across Chernobyl, the site has evolved from a disaster zone into a nature reserve, teeming with elk, deer and wolves, scientists said on Monday. "When humans are removed, nature flourishes - even in the wake of the world's worst nuclear accident," said Jim Smith, a specialist in earth and environmental sciences at Britain's University of Portsmouth. "It's very likely that wildlife numbers at Chernobyl are now much higher than they were before the accident." After a fire and explosion at the Chernobyl nuclear power plant in 1986 threw clouds of radioactive particles into the air, thousands of people left the area, never to return.
By Simon Johnson and Ben Hirschler STOCKHOLM/LONDON (Reuters) - A Japanese and a Canadian scientist won the 2015 Nobel Prize for Physics on Tuesday for discovering that elusive subatomic particles called neutrinos have mass, opening a new window onto the fundamental nature of the universe. Neutrinos are the second most bountiful particles after photons, the particles of light, with trillions of them streaming through our bodies every second, but their true nature has been poorly understood. Takaaki Kajita and Arthur McDonald's breakthrough was the discovery of a phenomenon called neutrino oscillation that has upended scientific thinking and promises to change understanding about the history and future fate of the cosmos.
"I was always wondering how we can think about this from a mechanical engineering perspective," she added. So Reid stepped out of the salon and into her laboratory. There she teamed up with fellow researchers Amy Marconnet and Jaesik Hahn to answer this question - what is the perfect amount of heat to apply when straightening hair without causing permanent damage? Reid said too much heat applied over a long period of time could destroy the natural curve in hair leaving it permanently damaged. "We are wanting to see the point at which hair becomes permanently straightened, it's otherwise called heat damage.
An asteroid impact in Mexico compounded by colossal volcanism in India 66 million years ago had killed about three-quarters of Earth's species including the dinosaurs. Scientists on Monday announced the discovery in northwestern New Mexico's badlands of the fossil remains of Kimbetopsalis simmonsae, a plant-eating, rodent-like mammal boasting buck-toothed incisors like a beaver that lived just a few hundred thousand years after the mass extinction, a blink of the eye in geological time.
By Simon Johnson and Ben Hirschler STOCKHOLM/LONDON (Reuters) - Three scientists from Japan, China and Ireland whose discoveries led to the development of potent new drugs against parasitic diseases including malaria and elephantiasis won the Nobel Prize for Medicine on Monday. Irish-born William Campbell and Japan's Satoshi Omura won half of the prize for discovering avermectin, a derivative of which has been used to treat hundreds of millions of people with river blindness and lymphatic filariasis, or elephantiasis. China's Tu Youyou was awarded the other half of the prize for discovering artemisinin, a drug that has slashed malaria deaths and has become the mainstay of fighting the mosquito-borne disease.
