Teens who talk excessively on the mobile phone and hold their phones close up to their right ear, score poorly in some memory tests, says a study (July) conducted by the Swiss Tropical and Public Health Institute, Switzerland. The results suggest that memory impairment might be a side-effect of radiation from overuse of mobile phones. Nearly 700 Swiss teens took part in a test of figural memory, which helps one recall abstract symbols and shapes. They participated in this memory test twice, one year apart. The researchers also surveyed teens on mobile phone usage. The researchers found that those who held their phone close to the right ear were exposed to higher levels of radiofrequency electromagnetic fields (RF-EMF) and scored worse after a year. “Potential risks to the brain can be minimised by using headphones or the speaker while calling, in particular when network quality is low and the mobile phone is functioning at maximum power,” says Martin Roosli, head of environmental exposures and health at the Swiss Tropical and Public Health Institute.

Researchers questioned 2,500 seven to eleven-year-olds and their parents across the UK about their eating and screen time habits. The survey indicates that primary school children who spend more than three hours online are more than four times likely to spend their pocket money on chocolate, chips, sugary drinks, and takeaways than their peers who browse for less than half an hour. These children were also 79 percent more likely to be overweight. The study found that, on average, children spent 16 hours a week online and watched 22 hours of television per week. Dr Jyotsna Vohra, head of cancer policy research, Cancer Research UK, says the study reveals a strong association between diet and advertising of junk food on television and the Internet. “It’s vital we see a 9 pm watershed on junk food adverts on TV and similar protection for children viewing adverts on-demand and online,” she says. Breastfeeding improves cognitive skills A new study conducted by Queen’s University, Belfast, in collaboration with University College Dublin, University College London and Cass Business School, UK shows that breastfeeding infants is likely to enhance their cognitive and memorisation skills. The study, which began in 1958, tracked approximately 9,000 participants from birth to age 50. Researchers found that infants who were breastfed for one month or more scored higher on memory tests in adulthood than those who were not breastfed. Breastfed children also recorded 10 percent higher household income. According to Dr. Mark McGovern, lead researcher and lecturer in economics at Queen’s Management School, Belfast, these findings are important as they show a direct correlation between infancy and memory and later economic development. “Promotional campaigns have highlighted…
