Medieval Ibiza was far from a quiet Mediterranean backwater. New DNA evidence shows that the island was part of a dynamic world linking Europe, North Africa and even the Sahel zone, south of Sahara. An international research team led by the Centre for Palaeogenetics (CPG), a joint venture between Stockholm University and the Swedish Museum…
Archaeologists in Mexico have unearthed a square stone altar used for human sacrifices during the Toltec Empire more than 1,000 years ago. The altar, human bones, obsidian knives and ceramic vessels were discovered during excavation for a transportation project near the archaeological site of Tula, about 55 miles (88 kilometers) north of Mexico City. In…
Rising sea levels are contributing to a phenomenon called “ghost forests,” which are groups of dead and dying standing trees that have been drowned by intruding saltwater. And all along the eastern U.S. where there used to be vibrant green trees, clusters of bare gray trunks appear. Now, researchers say studying how water cycles through…
In the last five years, Indigenous agriculture has received attention in academia as an alternative model, though on a smaller scale, to modern farming systems. Research has shown that some traditional farming systems, such as growing maize, beans and squash together, protect soil health, reduce biodiversity loss and support Indigenous knowledge, known as traditional ecological…
A box the size of a filing cabinet was lifted by crane, slowly moved and placed very carefully in the back of an unassuming lorry earlier this week. What looked like a casual drive around the Cern campus was actually a world-first experiment in transporting antimatter, the most expensive and volatile substance on Earth. To…
JUNO BEACH, Fla. (AP) — The veterinary staff at a Florida sea turtle hospital is getting help from space to monitor the animals they have rehabilitated. They’re particularly interested in amputees. Using satellite tracking devices in a collaboration between the Loggerhead Marinelife Center and the Smithsonian Conservation Biology Institute, scientists are learning how well sea…
Collaboration between the UCO’s Agronomy and Genetics departments was key to sequencing the genome of this pathogen, which is responsible for losses of up to €50 million per year. Cercospora leaf spot is an olive tree disease that causes defoliation and lower yields. It is caused by the fungus Pseudocercospora cladosporioides, which affects only the…
In March 2026, the first official day of the Northern Hemisphere’s spring felt more like summer across much of the southwestern United States. Numerous high-temperature records fell that day amid a bout of extreme heat. The extent and severity of the heat are represented on this map, which shows air temperatures on the afternoon of…

In the cold, wave-battered channels off southern Chile, scientists have identified what they say is a new species of the steamer duck genus Tachyeres, a group of notoriously aggressive, often flightless waterfowl found only in South America. Detail of the color pattern of the bill in adult specimens of the Chiloe steamerduck (A) and the…
