Dialog / When more blood does not mean more neuronal energy during REM sleep
REM sleep is already called "paradoxical sleep." The body is largely still, yet the brain is highly active. In humans, this is also the stage most closely associated with vivid dreaming. Our study, published in Communications ...
Phys.org / Homing in on the X-ray sky with eROSITA's second data release
The German eROSITA consortium (eROSITA-DE), which includes the University of Bonn and is led by the Max Planck Institute for Extraterrestrial Physics (MPE), has released its second major public data set, the "eROSITA Data ...
Phys.org / Indigenous territory maintains ecological stability amid agricultural expansion in the Brazilian savanna
"An island of biodiversity in a sea of monoculture": This is how a recent study characterized the Pimentel Barbosa Indigenous Territory (TIPB), located in the northeastern part of Mato Grosso state in Brazil's Central-West ...
Phys.org / Little red dots may mark temporary black hole phase
Since their discovery by NASA's James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has ...
Phys.org / Shark finning regulations have not significantly changed global trade, new analysis finds
Much like caviar, shark fins are a luxury product and delicacy in parts of the world. And like wild caviar, demand for shark fins has posed an incredible threat to species that can't reproduce quickly enough to keep up.
Tech Xplore / Ion pumping platform simultaneously cleans salty wastewater and recovers valuable metals
Industrial wastewater from electronics manufacturing, metal processing and other sectors often contains two difficult pollutants at once: high levels of salt and toxic heavy metals. Current treatment methods typically address ...
Medical Xpress / Microglia reveal sex-specific brain recovery mechanism after ketamine anesthesia
During ketamine anesthesia, the brain's nerve cells fall silent—as consciousness returns, they begin to reconnect. For the first time, researchers at the Institute of Science and Technology Austria (ISTA) have shown that ...
Phys.org / Newly discovered parasite linked to coastal seabird deaths
Along the Gulf Coast, black skimmers have long been a familiar sight—gliding just above the water with their bright orange beaks slicing through the surface to feed.
Phys.org / Surprising boiling behavior in liquids could advance future space missions
When astronauts travel deeper into space, every drop of fuel becomes critical, and keeping those fuels stable for months or even years is one of the biggest engineering challenges facing future missions. Now, University of ...
Phys.org / Math shows why your vote may not count the way you think it does
Mathematicians have shown that completely fair elections are—in a sense—impossible. No electoral system can guarantee both that local votes translate directly into local seats and that total seat distribution matches overall ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
Phys.org / New method flags hurricane rapid intensification up to five days ahead
The rapid intensification of a hurricane ranks among the most dangerous weather events on Earth. Storms such as Hurricane Michael, which crashed ashore in the Florida Panhandle with winds of 160 mph (about 257 km/h), and ...
