'Big, bad wolf' image flawed – scientists

Image copyrightRooobert Bayer Image caption Wolves are good at working together to get food rewardsNew research casts doubt on the idea that dogs are naturally more tolerant and friendly than wolves. In tests of cooperation skills, wolves outperformed their domesticated relatives. Scientists say the findings challenge assumptions about how dogs were tamed from wolves and came to live alongside humans. Previous evidence has suggested that the domestication process may have given dogs a more tolerant temperament. “We still have very much this idea of the big, bad wolf and the…

Image copyrightGetty Images Every year spent in education adds an average of 11 months to people’s lifespan, say scientists. The researchers say a person loses two months for every kilogram overweight they are – and seven years for smoking a packet of cigarettes a day. Unusually, the Edinburgh university team found their answers by analysing differences in people’s genetic code or DNA. Ultimately they think it will reveal new ways of helping us to live longer. The group used the genetic code of more than 600,000 people who are taking…

UK-Dutch-built Sentinel launches to track air quality

Image copyrightESA Image caption The Rockot lifted away from the Plesetsk Cosmodrome right on cueA UK-assembled satellite has launched from Russia on a mission to monitor air quality around the globe. Its Dutch-designed instrument will make 20 million observations daily, building maps of polluting gases and particles known to be harmful to health. Called Sentinel-5P, the spacecraft is a contribution to the EU’s Copernicus Earth-monitoring programme. S5P rode to orbit on a converted Russian intercontinental ballistic missile called a Rockot. The vehicle left the Plesetsk Cosmodrome at 12:27 local time…
