When bumble bees come up against invasive Argentine ants at feeding sites, they may win a direct confrontation but still return to the colony with less food. These encounters can leave bees with fewer resources even when they appear to come out ahead in a fight. Bumble bees already deal with significant challenges from pesticide…

Researchers are exploring a new generation of computers that operate using light, or photons, instead of electrical currents. Systems that rely on light to store and process information could one day run far more efficiently and complete calculations much faster than conventional machines. Light-driven computing is still at an early stage, and one of the…

New research from Rice University indicates that Jupiter dramatically reshaped the early solar system. According to the study, the giant planet created rings and wide gaps in the protoplanetary disk, helping to solve a long-standing mystery: why many primitive meteorites formed several million years after the very first solid materials. The work draws on hydrodynamic…

An international team of researchers has identified a previously unknown Neanderthal site on the southern edge of the Iberian Peninsula, located along Portugal’s Algarve coast. The findings, published in the journal Scientific Reports by Nature Publishing Group, describe the earliest evidence of Neanderthal hominids in Portugal. This discovery marks an important step forward in understanding…

Anxiety disorders affect roughly one in five people in the United States, making them among the most widespread mental health challenges. Although common, scientists still have many questions about how anxiety begins and is controlled within the brain. New research from the University of Utah has now pinpointed two unexpected groups of brain cells in…
