Phys.org / Supercomputer simulations map spliceosome motions in a two-million-atom human cell model
A new study from the Italian Institute of Technology (IIT), in collaboration with Uppsala University (Sweden) and AstraZeneca, shows how computational chemistry and supercomputers can help scientists better understand the ...
Phys.org / Ancient DNA reveals earliest known dogs lived alongside Ice Age humans
The bond between humans and dogs is one of nature's most enduring partnerships, but exactly when it began has long been a mystery. Now, a new study has turned back the clock. The study, titled "Dogs were widely distributed ...
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 / Alaska analysis shows continued loss of Arctic landfast sea ice
Sea ice is sticking to Alaska's northern coast for less time each year, according to 27 years of data analyzed by University of Alaska Fairbanks scientists. Such landfast ice, which stays attached to the shoreline instead ...
Phys.org / Saturday Citations: Birthday cetaceans; quantifying children's play experiences; placebos still effective
This week, we learned that across the animal kingdom, sperm cells have a short shelf life. A study implicated autoantibodies in the development of long COVID. And among its other drawbacks, the weedkiller glyphosate may foster ...
Phys.org / Scientists testing new scanning technology discover mysterious structure beneath an ancient Egyptian city
Archaeologists working in Egypt's Nile Delta may have discovered a tomb or temple dating back around 2,600 years while testing a new technology designed to locate structures buried deep beneath the surface. The team was studying ...
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 / 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 / JWST solves decades-long mystery about why Saturn appears to change its spin
Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science—why does Saturn appear to spin at a different speed depending ...
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 / 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 / Piezoelectric materials enable a new approach to searching for axions
Dark matter, a type of matter that does not emit, reflect or absorb light, is predicted to account for most of the matter in the universe. As it eludes common experimental techniques for studying ordinary matter, understanding ...
