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 / Fluorescent probes offer sharper view of plant tissues
Researchers at the Indian Institute of Technology Gandhinagar (IITGN) and the Regional Centre for Biotechnology, Faridabad, have developed and tested a new class of fluorescent probes that enable scientists to visualize xylem, ...
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 / Early Cambrian fossil uncovers key buoyancy structure at the dawn of cephalopod evolution
Extant and ancient cephalopods—including octopuses, squids, extinct ammonites, cuttlefish and nautiluses—have all had to solve the problem of buoyancy, whether they have hard external shells or not.
Medical Xpress / Supercharged millet could help children's gut health without usual supplement side effects
Every day in the urban slums of Mumbai, hundreds of young children were fed toddler-appropriate porridge, soft curry or fresh-baked goods. For some, these were made of ordinary pearl millet, an ancient grain common in the ...
Medical Xpress / 'Proust's madeleine' finally explained by neuroscience
A team of CNRS scientists has pinpointed the brain mechanisms behind the famous "Proust's madeleine" phenomenon, in which smells bring back vivid, emotional memories.
Phys.org / Diamond's newfound defect may tame vibrations that hinder quantum light sources
Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have discovered a new type of quantum light emitter in diamonds that could help overcome a number of challenges ...
Phys.org / Before North and South America were connected, their mammals found a way to intermingle
Until the Panamanian isthmus formed about 2.8 million years ago, North and South America were isolated continents with unique groups of animals. A riot of marsupials—mammals with brood pouches—and sloths in the south contrasted ...
Medical Xpress / How children talk can indicate risk for future mental health problems
Linguistic models that analyzed the words children used when talking about stressful events were better at predicting future mental health problems than a panel of human experts.
Phys.org / Scientists discover 210-million-year-old dinosaur in Zimbabwe
A newly discovered dinosaur from Zimbabwe is offering fresh clues to how the animals diversified, suggesting they spread across distinct ecosystems in southern Africa, scientists said Wednesday.
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 / Quantum neural networks get their first hardware test
Neural networks have transformed how machines find patterns in data, from recognizing faces in photos to predicting the shapes of proteins. So far, all of this progress has been made on ordinary classical computers, but with ...
