letter of the month

Belief and science I enjoyed reading the article by Richard Dawkins (September, p62). I am a Christian who fully accepts the evidence for evolution. I am saddened by the number of church leaders I meet who have little understanding of evolution or else a misunderstanding of evolution, a problem cited by Dawkins in his article. My advice to both church leaders and Dawkins would be the same: expand your reading list and your debating circles to gain an understanding of the other camp’s evidence. Susan Bremner, Scottish Borders WRITE IN AND WIN! The writer of next issue’s Letter Of The Month wins a bundle of wildlife photography books courtesy of the Natural History Museum. The books – two ‘coffee table’ collections, plus a beautifully illustrated desk diary – all feature winning photos from the Wildlife…

learning to read sharpens the brain’s visual capabilities

As we learn to read, a brain region known as the ‘visual word form area’ (VWFA) becomes sensitive to the letters and characters that make up written language. Now, a study at the University of Zurich has discovered that readers’ brains are more sensitive to visual information in general. The team used an fMRI scanner to study the brains of more than 90 adults from northern India with varying degrees of literacy, ranging from people unable to read to skilled readers. While in the scanner, participants saw sentences, letters and other random images such as faces. The brains of those with more advanced reading skills were activated more intensely by all images regardless of content, indicating an increased sensitivity to visual stimuli.…

siestas could improve cardiovascular health

Taking a nap once or twice a week can nearly half your risk of heart problems, a study at the University Hospital of Lausanne in Switzerland has found. The researchers monitored 3,462 Swiss residents for five years and found that those who took the occasional nap were less likely to get a cardiovascular disease such as a stroke. More research is needed to determine exactly how 40 winks lowers the risk of heart problems. However, it is unlikely to be solely down to nappers catching up on missed sleep, as the effect was also seen in those who napped despite getting a full night’s slumber.…

TEA DRINKERS Put the kettle on! Lovers of a cuppa have healthier brains than non-tea drinkers, a study at the National University of Singapore has found. MRI scans of a group of over-60s showed that the brains of tea drinkers are more efficiently connected. OPTIMISTS People with a ‘glass half full’ disposition are less likely to have a heart attack, researchers in New York have found. They gathered together data from 15 studies involving more than 200,000 participants and found that those with high levels of optimism were 35 per cent less likely to suffer a heart attack.…

POSING POLITICIANS Striking a power pose – the Wonder Woman-esque stance touted in some quarters as a way to reduce stress levels and increase confidence – is no more effective than simply standing up straight, a review of 40 previous papers carried out at Iowa State University has found. CYBERBULLIES Trolls beware! Researchers at Binghamton University have developed an AI that can identify aggression, harassment and bullying in social media posts with 90 per cent accuracy. They hope the tech will be used to flag up cyberbullies and get their accounts deleted.…
