Researchers trained a large language model to read medical charts, looking for signs that kids with ADHD received the right follow-up care when using new medications.
When you are feeling hungry, the brain takes the necessary steps toward consuming a meal. Many of these steps are not well known, but a new study reveals brain circuits and chemical messengers that contribute to the regulation of meal...
Alcohol use disorder (AUD) disrupts cognitive flexibility, crucial for learning and adapting to change. New research reveals that chronic alcohol exposure alters the firing patterns of cholinergic interneurons (CINs), key neurons in the...
There is more research than ever focused on reflecting sunlight away from the planet to cool the climate – but there are still far more questions than answers about the effects
A US ban on the video-sharing app TikTok is set to take effect in early 2025 – but the country's Supreme Court and President-elect Donald Trump could still change that

We asked New Scientist writers to pick their favourite sci-fi short story. From H.G. Wells’s The Time Machine to Octavia E. Butler’s Bloodchild, via stories from George R. R. Martin and Ursula K. Le Guin, here are the results
Every Monday and Friday for the rest of December we will publish some of our favourite audio long reads of 2024, in case you missed them, with an introduction from the editorial team to explain why we’ve chosen it. From August: By the...
Impatience, studies of more than 1,200 people found, is the emotion people feel when they face a delay that seems unfair, unreasonable, or inappropriate -- like a traffic jam outside of rush hour, or a meeting that should have ended 15...
Artificial intelligence that is as intelligent as humans may become possible thanks to psychological learning models, combined with certain types of AI.
Mutational signatures etched into the cells' genome by an anti-cancer drug called temozolomide (TMZ) uncover an Achilles' heel for TMZ chemotherapy resistance, according to new research.
Antibodies can improve the rehabilitation of people with acute spinal cord injury. Researchers have investigated this with promising results. For the first time, it was possible to identify patient groups that displayed a clinically...
Hand choice, an unconscious decision, is influenced by target-related information, but if these are non-informative, the choice will be approximately 50-50. In this equilibrium situation, non-target information may also aid in...
Researchers have discovered a surprising link between a chronic gut infection caused by a common virus and the development of Alzheimer's disease in a subset of people. It is believed most humans are exposed to this virus -- called...
The best way to deal with narcissistic people in your personal life may be the hardest advice to take, according to an expert who has studied narcissism for more than 20 years. The best course of action is to identify narcissistic people...
