Originally developed for children, the diagnosis of ADHD is often difficult to make in adults. This is partly because the diagnostic criteria are based on behaviour in children. When diagnosing adults, however, these criteria are often based on adults’ subjective experiences, e.g., of having difficulty concentrating or being very impulsive. “The rising number of adults…
Liverpool John Moores University. Nature Tests on the skull could give new insights into ancient history A DNA bone test on a man who lived 4,500 years ago in the Nile Valley has shed new light on the rise of the Ancient Egyptian civilisation. An analysis of his skeleton shows he was 60 years old…
A new technology that uses clinical MRI machines to image metabolic activity in the brain could give researchers and clinicians unique insight into brain function and disease, researchers at the University of Illinois Urbana-Champaign report. The non-invasive, high-resolution metabolic imaging of the whole brain revealed differences in metabolic activity and neurotransmitter levels among brain regions;…
A widely-used agricultural chemical sprayed on American and Australian fruits and vegetables to prevent fungal disease is killing beneficial insects critical for pollination and ecosystem health, new Macquarie University research shows. The study, published in Royal Society Open Science, found chlorothalonil – one of the world’s most extensively used fungicides – severely impacts insect reproduction…
The predicted path of A11pl3Z, making it the third interstellar object ever seen in the solar system CSS, D. Rankin A potential interstellar object has been spotted zipping through our solar system, and amateur and professional astronomers around the world are now racing to train their telescopes in its direction, allowing them to refine models…
In chimpanzee communities, strong social ties can be a matter of life and death not just for the adults who form them, but for their kids, too. A new federally-funded study of wild eastern chimpanzees (Pan troglodytes schweinfurthii) from Gombe National Park shows that female chimpanzees who were more socially integrated with other females in…
Two concentric rings appear around the supernova remnant SNR 0509-67.5, indicating that it exploded twice ESO/P. Das et al. Background stars (Hubble): K. Noll et al. A white dwarf star around 160,000 light years away appears to have exploded twice – the first evidence astronomers have seen that such supernovae involve a double detonation. White…
A new study challenges the belief in a universal “pet effect” on human well-being. Using data collected during COVID-19 lockdowns, researchers found no significant change in respondents’ well-being when they acquired or lost a pet in their household. The findings suggest that, even during a time of extreme isolation, human-animal bonds may not be as…
Tim Dodd Climate and science reporter Getty Images Record low water levels in the Amazon basin disrupted drinking water for thousands of people From Somalia to mainland Europe, the past two years have seen some of the most ravaging droughts in recorded history, made worse by climate change, according to a UN-backed report. Describing drought…
In the study, researchers from Canada, New Zealand and Mexico reported on 34 interactions spanning two decades in which orcas in the wild attempted to offer food to humans. The incidents took place in oceans around the world, from California to New Zealand to Norway to Patagonia. “Orcas often share food with each other –…
