Phys.org / Brain structure volume linked to increased social tolerance in macaques
Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described ...
Phys.org / Marine biologists create a family history of San Diego's giant kelp over more than four decades
The growth form of giant kelp (Macrocystis pyrifera) is composed of shoots known as stipes instead of branches. From one parent holding fast to the hard bottom might come as many as 150 stipes. Typically, the tips of the ...
Phys.org / Feral horses and cattle create more resilient nature, rewilding study reveals
Protected natural areas across Europe are changing. Climate change, with rising temperatures and heavy rainfall, is turbocharging the growth of shrubs and trees, choking the flowers and insects that need the light and heat ...
Phys.org / 3D imagery helps bring world's ant diversity to life
For more than a decade, Evan Economo's lab has been using micro-CT machines to scan insect specimens. The resulting X-ray images help researchers study the form and structure of insects—a subfield of entomology known as ...
Medical Xpress / Brain-clearing cells offer clues to slowing Alzheimer's disease progression
Accumulation of the protein tau in the brain is one of the hallmarks of Alzheimer's disease. In a paper published in Cell Press Blue, researchers report a previously unknown mechanism that appears to enable the buildup of ...
Phys.org / Protecting wildlife from genetic collapse with newly identified 'early warning signals'
A new study reveals that habitat fragmentation can lead to sudden "tipping points" where a species' genetic health unexpectedly collapses after appearing stable for long periods. By merging network theory with population ...
Medical Xpress / Digital transformation of food retail is reshaping food access for consumers
A research report published in the Journal of Nutrition Education and Behavior examines how the rapid digitalization of the retail food environment is reshaping food access in the United States and highlights implications ...
Phys.org / Polymers that crawl like worms: How materials can develop direction without being told where to go
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different intensities can spontaneously develop directional, persistent motion when densely ...
Phys.org / ESA's Mars orbiters watch solar superstorm hit the red planet
What happens when a solar superstorm hits Mars? Thanks to the European Space Agency's Mars orbiters, we now know: glitching spacecraft and a supercharged upper atmosphere.
Phys.org / Thermogenetics: How proteins are controllable by heat
Protein activity can be precisely regulated via subtle changes in temperature using heat-sensitive switches. Underlying this capability is a novel modular design strategy developed by researchers at the Institute of Pharmacy ...
Phys.org / JWST reveals surprising secrets in Jupiter's northern lights
An international team of scientists, led by a Ph.D. researcher from Northumbria University, has made further discoveries about a spectacular feature of Jupiter's northern lights, revealing a never-before-seen temperature ...
Phys.org / Drones capture rare harbor porpoise mating behavior off Shetland
Drones flying above the waters of Shetland have captured rare footage of harbor porpoises gathering in unusually large groups and engaging in mating behavior. The footage, gathered between 2019 and 2023, provides one of the ...
