AI reads 3D tooth microwear to reconstruct diets of early human ancestors

The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates and hominins throughout human evolution. The microsc

Ultra-precise technology can count damaged DNA fragments

The Korea Research Institute of Standards and Science has developed an ultrasensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA (sedDNA)" fragments generated during cellular DNA repair. This technology enables h

Flooding rains, ocean gains: How a huge Murray flood gave the sea a feast

For decades, the rivers of the Murray-Darling Basin have been heavily regulated by dams and irrigation networks. As a result, the volume of water entering the ocean is about 60% smaller than 100 years ago. But nature broke through during massive floods over the summer of 2022–23,

Global rice paddy greenhouse gas emissions have doubled during the past six decades, study

Rice paddy greenhouse gas emissions have doubled during the past 60 years—but practical farm changes could cut methane emissions and support global climate targets without reducing food production, a team led by Boston College scientists reports in the journal Nature Food.

Ocean warming above 1.5°C triggered year-round marine disruption across globe, study shows

Researchers at King Abdullah University of Science and Technology (KAUST) led one of the first global assessments of how marine ecosystems responded during the first year when global temperatures temporarily exceeded 1.5°C above pre-industrial levels.

ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms, t

Human activity has driven retreat of Antarctica's fastest melting glacier

Human-driven climate change significantly intensified the retreat of one of the most important glaciers in Antarctica during the 20th century. The Pine Island Glacier, which drains a large part of the West Antarctic Ice Sheet into the Amundsen Sea, is one of the biggest contribut

Red-tailed hawks maintain flight performance despite missing feathers

Red-tailed hawks can compensate for feather loss during molt by subtly changing their wing and tail movements, according to a new study by University of California, Davis, researchers in the College of Engineering and the Weill School of Veterinary Medicine.

One of the most distant 'leaky' galaxies ever found may reveal how the universe reionized

Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.
