The approach harnesses the power of bacteria to transform post-consumer plastic into L-DOPA, a frontline medication for the neurological disorder. It is the first time a natural, biological process has been engineered to turn plastic waste into a therapeutic for a neurological disease, researchers say. https://phys.org/news/2026-03-plastic-bottles-parkinson-drug-bacteria.html Mon, 16 Mar 2026 06:00:03 EDT news692627939 Scientists have shed light on some reasons why young people with attention deficit hyperactivity disorder—known as ADHD—are prone to anxiety and depression. Young people with ADHD symptoms are more likely to experience emotional issues such as anxiety and low mood partly because ADHD puts them at risk of low self-esteem and having a parent with poor mental health. The study, led by the University of Edinburgh, is the first to study a wide range of factors which link ADHD symptoms and mental ill health symptoms over time. The research is published in the Journal of Attention Disorders. https://medicalxpress.com/news/2026-03-link-adhd-mental-ill-health.html Thu, 12 Mar 2026 13:00:01 EDT news692538961 The humble breadcrumb could hold the key to cutting out fossil fuels from one of the chemical industry's most widely used reactions, according to a new study. Scientists have found a one-pot microbial formula that uses waste bread to replace fossil fuel-derived hydrogen in hydrogenation—a chemical reaction used extensively to manufacture foods, pharmaceuticals, plastics and other everyday products. https://phys.org/news/2026-02-breadcrumbs-fossil-fuelfree-production-everyday.html Mon, 23 Feb 2026 05:00:06 EST news690820237 There is little evidence that the amount of time young people spend on social media is linked to later mental health issues, according to a new study. Research following more than 3,000 young people found that low to average social media use at ages 11 and 14 did not strongly predict mental ill health three years later, including depression and anxiety, self-harm and suicide attempts. https://medicalxpress.com/news/2026-02-social-media-teens-uk-weak.html Mon, 09 Feb 2026 15:36:50 EST news689873761 Scientists have created a new type of material that could enable common electronic devices to work faster and use less energy, a study suggests.

The study focused on CTNNB1, a gene that produces the protein β-catenin, which helps regulate tissue growth and repair. When β-catenin is disrupted, cells can begin uncontrolled growth—a hallmark of cancer.
