ADHD stimulants appear to work less by sharpening focus and more by waking up the brain. Brain scans revealed that these medications activate reward and alertness systems, helping children stay interested in tasks they would normally avoid. The drugs even reversed brain
For decades, research and understanding of the diverse bone raw material used by the Late Prehispanic Period (~1220 to 330 cal BP) people of the Sierras de Córdoba were scarce. However, Dr. Matías Medina and his colleagues, Sebastián Pastor and Gisela Sario, have published a
Researchers found that U.S. metal mines already contain large amounts of critical minerals that are mostly going unused. Recovering even a small fraction of these byproducts could sharply reduce dependence on imports for materials essential to clean energy and advanced
Advanced computer models can quantify the impacts of climate change and other environmental challenges, providing deep insights into things like streamflow, vegetation, wildlife and even the risk of wildfires.
What if the pages of an old book could tell us who touched them, what medicines they made, and even how their bodies responded to treatment?
By analyzing the archival data from the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected the outflow of a nearby galaxy known as NGC 1266. Results of the new study, presented Dec. 11 on the arXiv pre-print server, could
Thousands of glaciers will vanish each year in the coming decades, leaving only a fraction standing by the end of the century unless global warming is curbed, a study showed on Monday.
Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed using the James Webb Space Telescope, which was able to isolate the blast from its
Tiny lab-grown brains are offering an unprecedented look at how schizophrenia and bipolar disorder disrupt neural activity. Researchers found distinct electrical firing patterns that could identify these conditions with high accuracy. The discovery opens the door to more
A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our solar system. Their work, published in The Astrophysical Journal Letters, used NASA's JWST to reveal an alien atmosphere in an unexpected place—an ancient,
Scientists have uncovered why big predators like sharks spend so much time in the ocean’s twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the day and rise at night to feed, linking deep and surface food webs. Using
In the age of dinosaurs—before whales, great whites or the bus-sized megalodon—a monstrous shark prowled the waters off what's now northern Australia, among the sea monsters of the Cretaceous period.
Researchers say fusion reactors might do more than generate clean energy—they could also create particles linked to dark matter. A new theoretical study shows how neutrons inside future fusion reactors could spark rare reactions that produce axions, particles long suspected to
Deep in Iraq's southern desert, bulldozers and earthmovers spread layers of moist clay over sand dunes as part of a broader effort to fight increasingly frequent sandstorms.
Weight loss restored healthy metabolism in both young and mid-aged mice, but the brain told a different story. In mid-aged animals, slimming down actually worsened inflammation in a brain region tied to appetite and energy balance. While this inflammation eventually subsided,
