Risso's dolphins around the British Isles are part of a single population—genetically distinct from those elsewhere in the Atlantic, new research shows. Scientists studied the DNA of dolphins that stranded in England, Scotland and Wales from 1992 to 2016.

While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes up part of the lighter-element composition. Data from

A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to m

University of Queensland research has shown microbes could give Australian-grown chocolate an edge in the global market. Working with growers in Far North Queensland, scientists found the cocoa fermentation process may have a bigger influence on the flavor of chocolate than the c

Scientists find ruminants emit more of greenhouse gas individually than cows, although total contribution tiny compared with domesticated livestockWhen cows belch and fart they release methane, which is warming the planet, but how does this compare with the digestive gases emitte

Dinosaurs are famous for being big, from the towering Tyrannosaurus rex to the colossal Apatosaurus. But a new study published today in the journal Evolution by scientists at the American Museum of Natural History and Princeton University suggests that one of the greatest mysteri

Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also estimate

More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms. Researchers separated microbes that lived in his body during his lifetime from those that arrived after his death, uncovering traces of his original gut

The trillions of microorganisms living in our intestine influence our health, from digestion and metabolism to immunity. Yet scientists still struggle to understand how these microbes shape these important physiological functions because gut microbiomes are extraordinarily comple

During a "Washington Post Live" panel discussion with ASU President Michael Crow, President Sally Kornbluth explored how universities are preparing the next generation of scientists to lead in America’s rapidly changing technological landscape.

By focusing on electrolytes, MIT scientists are making sodium-metal batteries a more practical energy storage option. O recorte ajuda a contextualizar a pauta dentro de IA.
