Phys.org / Major volcanic eruptions might be driven by gas dissolving back into magma
Understanding what triggers large volcanic eruptions is crucial for hazard assessment, but the exact mechanism driving these eruptions is still poorly understood. The prevailing theory is that volatile exsolution—gas coming ...
Phys.org / Japan's giant caldera volcano is refilling 7,300 years later
The magma reservoir of the largest volcanic eruption of the Holocene is refilling. This Kobe University insight on the Kikai caldera in Japan allows us to understand giant caldera volcanoes like Yellowstone or Toba more generally ...
Phys.org / What's for dinner? Tooth enamel reveals what early Mesopotamians really ate
We can learn a great deal about the lives and social structures of civilizations thousands of years ago by studying what they ate. While actual food remains are few and far between, scientists can reconstruct ancient menus ...
Phys.org / Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen
Three-hundred-million years ago, Earth was very different. The continents had coalesced into Pangea, which was dominated in its equatorial regions by vast coal-swamp forests. With high atmospheric oxygen levels, wildfires ...
Phys.org / Masripithecus: A new Miocene ape from Egypt sheds light on the origins of modern apes
In a study published in Science, an international research team from the Mansoura University Vertebrate Paleontology Center (Egypt) and the University of Southern California (U.S.) describe Masripithecus moghraensis, a newly ...
Phys.org / Extreme global climate outcomes are possible even at 2°C warming, study warns
Extreme climate impacts on people and the environment are often associated with very high levels of global warming (3 or 4°C). A new study led by the Helmholtz Centre for Environmental Research (UFZ) shows that this assumption ...
Phys.org / He suddenly couldn't speak in space. NASA astronaut says his medical scare remains a mystery
The astronaut who prompted NASA's first medical evacuation earlier this year said Friday that doctors still don't know why he suddenly fell sick at the International Space Station.
Phys.org / How lifetime stress drives abnormal behaviors in lab monkeys
It is not unusual for laboratory monkeys to engage in abnormal repetitive behaviors (ARBs), such as pacing and hair-plucking. Conventional thinking is that these actions are linked to recent stresses or current housing conditions. ...
Phys.org / Study explains Antarctic sea ice growth and sudden decline
A new Stanford University study has helped solve a mystery about dramatic swings in sea ice extent around Antarctica.
Phys.org / Implantable 'living pharmacy' produces multiple drugs inside the body
A multi-institutional team of scientists, co-led by Northwestern University, has taken a crucial step toward implantable "living pharmacies"—tiny devices containing engineered cells that continuously produce medicines inside ...
Phys.org / Artemis II astronauts arrive at Florida launch site for first moon trip in 53 years
The astronauts set to become the first lunar visitors in more than half a century arrived at their launch site Friday, joining the towering rocket that stands poised to blast off next week and send them around the moon.
Phys.org / Earth's magnetic field creates a previously undetected pocket of protection from radiation on the moon
High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, however, is protected by its magnetic field, which creates a protective shell around the planet that ...
