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. At its heart is Pueblo Bonito ("Pretty...

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.

NASA captures a stunning transformation in Australia's red outback

Australia's normally dry, rust-colored outback has erupted into a spectacular carpet of wildflowers after unusually heavy rains, potentially producing its most impressive bloom in nearly 20 years. NASA satellite images capture the stunning transformation, which has even brought rare flowers to the grounds of a remote deep-space observatory.

Rescued weather records reveal hot days became nearly twice as common in the Congo Basin over two decades

New research led by Vrije Universiteit Brussel (VUB) and published in the journal Earth System Dynamics shows a clear warming signal across the Congo Basin since the 1960s, using historical weather records from the Democratic Republic of the Congo (DRC). These records come from the paper archives of the Institut National pour l'Etude et la Recherche Agronomiques (INERA) in Yangambi, DRC, and the State Archives of Belgium.

Scientists discover a hidden factor that can make or break chemical reactions

Researchers discovered a hidden factor that can determine whether chemical reactions succeed or fail, and then used it to boost the proportion of the desired product from 16% to 97%. By controlling acidity near electrodes, they developed a promising way to manufacture chemicals for plastics, medicines, and other products using oxygen and electricity instead of hazardous added oxidants.

'It could have been a very different history': Researchers are finally starting to pin down how many Indigenous people were living in the Americas when Columbus arrived

When Christopher Columbus made landfall in the Americas on Oct. 12, 1492, he encountered Indigenous Lucayans living on the Bahamian island now called San Salvador. Columbus wrote in his diary about "great multitudes of men" who greeted him that day, bartered with him and told him about other groups who lived on nearby islands. But within a few decades after Columbus' arrival, the Indigenous people of the Americas were decimated by what anthropologist Eric Wolf called the "Great Dying" — a combination of epidemic disease, warfare and enslavement that led to a rapid decline in the Native population. For centuries, researchers have been trying to figure out how many Indigenous people lived in t...

Scientists discover vanilla’s hidden healing potential

Scientists have discovered that vanillin, the compound that gives vanilla its distinctive flavor, has powerful properties that could help fight infections, reduce inflammation, and promote wound healing. The inexpensive, widely available ingredient could one day become an important component of advanced wound treatments and regenerative medicine.

Just 10 minutes of daily exercise could unlock deeper sleep

Getting better sleep might be as simple as moving a little more every day. Researchers at The University of Texas at Austin found that people who exercised more frequently experienced more deep, restorative sleep, which is essential for brain recovery, memory, and emotional well-being. Surprisingly, just 10 minutes of moderate to vigorous exercise per day was associated with measurable benefits, while even light activities like walking and standing breaks were linked to better sleep and mood.

Wildlife populations have declined 73% since 1970—but many of the world's animals still aren't being counted

Wildlife populations around the world have declined by an average of 73% since 1970. That's according to the WWF's new 2026 Living Planet Index—a major estimate, updated every two years, of the changing state of nature. This does not mean that 73% of the world's animals have disappeared. Rather, it is the average decline in the size of wildlife populations being monitored.

Scientists discover why a 100-year-old mushroom disease won't go away

Scientists have uncovered a surprising secret behind a mushroom disease that has frustrated growers for more than a century: It involves more than 17 species of harmful bacteria, not just one. The discovery could explain why treatments have struggled to stop the disease and open the door to more effective, eco-friendly solutions.

The hidden math of Alzheimer's could point to new treatments

Mathematics may hold unexpected clues to understanding Alzheimer’s disease. Scientists have developed a model showing how common metals like copper and zinc may influence the buildup of proteins associated with the disease, while also exploring possible ways to stop the process. The findings could help researchers identify promising strategies for preventing harmful plaque formation.
