Image copyrightGetty Images Image caption Losses of rare insects are well documented, but there is little research on insects as a wholeIt’s known as the windscreen phenomenon. When you stop your car after a drive, there seem to be far fewer squashed insects than there used to be. Scientists have long suspected that insects are in dramatic decline, but new evidence confirms this.

DNA study provides insight into how to live longer

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…
