1,200-year-old burial in Latvia holds people who died of 'sharp force' injuries, possibly from a Viking raid
Six people buried in a single grave in Latvia more than 1,000 years ago may have been killed in a bloody Viking raid, a new study suggests.Genetic research into the deceased — four men, a boy and a girl — reveals family connections: The boy was the son of one of the men, while another man was a third-degree relative, perhaps a first cousin or great uncle, the researchers found.The father, the relative, and one other man died from "sharp force" injuries — maybe wounds from an ax or a sword; but it's unknown how the other three individuals died, the researchers reported in the study, which was published in the September issue of the Journal of Archaeological Science: Reports. One possibility i...

New sensor uses slowed light to detect gravitational pull of tiny objects
Gravity, the attraction between objects with mass, is the weakest of the four fundamental forces governing physical processes. Detecting the tiny gravitational pull of objects that are just a few millimeters in size and have a very small mass is extremely challenging.

Hybrid quantum computers could finally get to grips with light and matter
Many of nature's most important processes depend on how particles of matter interact with light and other force-carrying particles. So far, however, it has proven difficult for conventional computers to determine how individual particles behave in these interactions.

7 extraordinary Indigenous sites in the US, from Chaco Canyon to Chimney Rock
The prehistory of Indigenous Americans goes back tens of thousands of years before the 1492 arrival of Christopher Columbus in the Bahamas, and recent scientific studies suggest prehistoric people were on the American continents a lot longer than many experts believed. For Indigenous Peoples Day, here are seven locations in the United States that outline the Native American story.1. Chaco Canyon (New Mexico)(Image credit: jjwithers via Getty Images)This centuries-old settlement, whose name may be a Spanish adaptation of an Indigenous word for the area, was the political and ceremonial center for the Ancestral Puebloan people from about A.D. 850 to 1250.

Popular weight loss drugs linked to a surprising fingernail problem
Popular GLP-1 weight loss drugs, such as Ozempic and Wegovy, have been linked to unexpectedly high rates of nail detachment, hair loss, and scalp inflammation, with some problems occurring several times more frequently among users. Researchers found that weight loss alone could not fully explain the differences, suggesting there may be more to these overlooked symptoms.

Scientists find hidden driver of aging and a simple amino acid that fights memory loss in mice
Scientists discovered that declining levels of a protein called Menin may help drive aging, and restoring it in older mice reversed several age-related changes in just 30 days. Even more surprisingly, supplementing with a simple amino acid called D-serine improved memory and learning, offering a potential new approach to age-related cognitive decline.
