Europe's most active volcano may have a secret origin

Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma that are pushed upward through cracks created by shifting tectonic plates. If confi

Peering into materials down to the nanoscale in the COCOON lab

A new Tufts University imaging facility is doing something that most microscopy centers in the world cannot: allowing scientists to examine a butterfly wing, a living tissue or a microchip and reveal its physical structure, molecular chemistry and elemental composition across eve

Astronomers reveal how clouds shape the hidden interiors of the galaxy's most common plane

Sub-Neptunes are the most common type of planet in our galaxy. Bigger than Earth but smaller than Neptune, these worlds remain deeply mysterious because scientists still do not know what they are made of. What astronomers really want to figure out is their interior composition. T

Researchers link the mass extinction of once-dominant marine groups to intolerable heat, d

A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land animals died off during the Permian–Triassic extinction eve

NASA space telescope maps magnetic fields of 'Lighthouse' pulsar

For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into the structure of s

Physical laws explain why most flies evolved similar flight, with mosquitoes as outliers

A new study in PLOS Biology of 133 species of flies, mosquitoes and their relatives shows that most species fly in surprisingly similar ways. Physical and aerodynamic laws shape the evolution of their flight behavior more strongly than previously thought. Mosquitoes prove to be a

NASA satellites are watching Earth's newest island rise from the sea

A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close

Collective agreements are least common where workers need them most

Workers earning the lowest wages are the least likely to be covered by collective agreements in Germany, despite being the group for whom these protections are arguably most important. In 2021, only 34% of workers in the lowest wage decile were covered by collective agreements, c
