Medical Xpress / Alcohol drives opposite brain circuit changes in amyloid and tau Alzheimer's models
Alcohol use has been associated with an increased risk of cognitive decline and dementia. But new research from Texas A&M University's Naresh K. Vashisht College of Medicine at Texas A&M Health suggests the relationship between ...
Phys.org / Ancient atmospheric oxygen found in iron ore deposits
How do some of geology's most mysterious iron ore deposits form? This question has preoccupied the geosciences for more than a century. An international research team led by Dr. Stefan Peters from the Leibniz Institute for ...
Phys.org / The language of play: Hyenas use facial expressions and vocalizations to de-escalate
Scientists observed spotted hyenas (Crocuta crocuta) playing in the wild and found that their precise, sophisticated communication is on par with that of many primate species. Hyenas play and romp with one another at all ...
Phys.org / Unraveling a long-standing solar mystery: The extreme thinness of the sun's tachocline layer
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun's tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions ...
Phys.org / Steering light in a flash: New chip redirects light beams in less than a trillionth of a second
Light can carry enormous amounts of information at extreme speeds, making photonic technologies promising for the development of faster communications, more powerful computing systems and more sensitive sensors. But for light ...
Phys.org / Peru Amazon highway tied to 400% dengue surge within 5 kilometers of road
New roads bring changes to the regions they traverse. They can enable job opportunities, access to medicine and health care, and electricity. But they also disrupt local ecosystems and can have surprising consequences for ...
Dialog / Catching hydrogen in the act: Tracking the absorption process over time
If you're looking for hydrogen on the elemental chart, it won't take you long to find it. It is right there at the beginning, the lightest possible material. One electron, one proton—that's it. Simple, minimalistic, the Marie ...
Tech Xplore / Smaller homes could cut Europe's CO₂ building emissions
Buildings are responsible for around 40% of CO2 emissions in the European Union. This means the building sector has a central role to play in achieving the EU's climate targets by 2050. An EU research project involving Graz ...
Phys.org / Study links newspaper closures to distorted crime reporting
Local newspapers serve as a vital check on public institutions, including law enforcement, according to new research from the University at Buffalo School of Management. Published in the American Journal of Criminal Justice, ...
Phys.org / Quantum computers model nine fusion fuel material configurations for first time
A team of scientists from Oak Ridge National Laboratory, Cleveland Clinic and IBM has calculated nine molecular configurations of a promising material to produce fuel for fusion energy—the first known instance of such computations ...
Tech Xplore / Researchers develop a new way to build molecular 'ladders' for organic electronics
Ladder-type oligothiophenes are an important class of sulfur-containing π-conjugated molecules. Because their fused, ladder-like structures can support efficient electronic interactions, they are widely studied as core motifs ...
Phys.org / Indigenous peoples in the Amazon face massive cultural and ecological loss due to climate change
The Amazon region, Earth's most important ecosystem, is home to more than 400 Indigenous groups that use thousands of rainforest plant species. They pass on their knowledge of the flora primarily through oral tradition, usually ...
