Where cannabis stores cluster, emergency visits climb

A population-based natural experiment investigated how living near cannabis retail stores relates to cannabis-related harms. The researchers found a connection between store exposure and higher rates of harm, with the largest increases appearing in neighborhoods that had many stores located close together. These results indicate that limiting the number of…

Repeated head impacts may quietly break the brain’s cleanup system

A new study examining cognitively impaired professional boxers and mixed martial arts fighters reports that the brain’s waste-clearing system appears to weaken after repeated blows to the head. These findings are scheduled to be presented next week at the annual meeting of the Radiological Society of North America (RSNA). Sports-related…

Scientists find toxic metals hidden in popular plastic toys

Researchers from the University of São Paulo (USP), working together with the Federal University of Alfenas (UNIFAL), have found significant amounts of hazardous chemicals in plastic toys sold throughout Brazil. The team examined 70 products, including both imported and locally produced items, creating what they describe as the most extensive…

A popular “essential” medicine may be putting unborn babies at risk

Researchers Dr. Adrienne Chan and Professor Ian Wong of Aston University examined how antiseizure medications are used around the world. The World Health Organization lists valproate as an essential medicine, yet the drug can lead to serious neurodevelopmental disorders when taken during pregnancy. Findings show that access to antiseizure treatments…

Miracle material’s hidden quantum power could transform future electronics

Graphene is a remarkable form of carbon, built from a single layer of tightly connected atoms that is only one atom thick. Despite its thinness, it is highly stable and conducts electricity extremely well. Because of these qualities, graphene is considered a “miracle material” and is already being explored for…

A strange ancient foot reveals a hidden human cousin

Thanks to newly discovered fossil bones, scientists have now been able to match an enigmatic 3.4-million-year-old hominin foot, first found in 2009, to a species that is different from the famous fossil Lucy. This link strengthens the case that two separate species of early human ancestors were living in the…

Scientists uncover the brain’s hidden learning blocks

Artificial intelligence can now craft award-winning essays and help doctors detect disease with impressive accuracy. Yet when it comes to true mental flexibility, living brains still have the clear advantage. Humans can adjust to new situations and information with remarkable ease.

Hidden mitochondrial DNA damage may be a missing link in disease

A newly identified kind of DNA damage inside mitochondria, the small structures that supply cells with energy, may help explain how the body detects and reacts to stress. The work, led by researchers at UC Riverside and published in the Proceedings of the National Academy of Sciences, suggests that this…

X-ray movies reveal how intense lasers tear a buckyball apart

Understanding how many atoms move and interact inside laser-driven polyatomic molecules is essential for any attempt to guide chemical reactions using intense light. With the help of ultrashort, high-power X-ray pulses created by accelerator-based free electron lasers (FELs), scientists can now directly observe how strong laser fields rapidly reshape molecular…
