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 ...
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 / Exotic harvestmen once lived in Europe
A German-Bulgarian research team led by SNSB paleontologist Christian Bartel has discovered a new species of harvestman in 35-million-year-old Ukrainian and Baltic amber. The animal is related to harvestmen that are now extinct ...
Phys.org / Study in search of a tropical spring is first to show some birds flip their breeding season in response to climate
In 2014, Felicity Newell joined the Florida Museum of Natural History as a doctoral student, then promptly left the country in search of a tropical spring. It's a concept she started thinking about while doing biological ...
Phys.org / Physicists create optical phenomenon inspired by the quantum Hall and spin Hall effects
Researchers at the Würzburg site of the Cluster of Excellence ctd.qmat have succeeded in transferring the topological quantum Hall and spin Hall effects to a hybrid light-matter system by harnessing targeted material design. ...
