Medical Xpress / Proteins that spread Parkinson's pathology in the brain identified
Two proteins found on the surface of motor neurons in the brain may be essential in the progression of Parkinson's disease, according to new Yale School of Medicine (YSM) research.
Phys.org / Webb finds early-universe analog's unexpected talent for making dust
Using NASA's James Webb Space Telescope, astronomers have spotted two rare kinds of dust in the dwarf galaxy Sextans A, one of the most chemically primitive galaxies near the Milky Way.
Phys.org / Swinging abyss: Oxygen isotope analysis shows less dynamic Antarctic ice sheet in Oligocene period
Oxygen isotopes data enable researchers to look far back into the geologic past and reconstruct the climate of the past. In doing so, they consider several factors such as ocean temperature and ice volume in polar regions. ...
Phys.org / Dentin inside wolffish teeth is a rare material: When compressed along its length—it also shrinks in width
The Atlantic wolffish is known for its powerful bite, capable of crushing hard-shelled prey with ease. Now, researchers have discovered that the fish's teeth don't just withstand these extreme forces, they respond in a way ...
Phys.org / Frequent Arctic wildfires could cut snow cover by 18 days, impacting global climate and ecology
The correlation between Arctic wildfires and abnormal snow cover under global warming is of growing concern. A comprehensive quantitative assessment by researchers at The Hong Kong Polytechnic University (PolyU) has shown ...
Tech Xplore / Grasshopper wings inspire gliding robot design
A collaboration between Princeton University engineers and entomologists at the University of Illinois Urbana-Champaign began with the researchers chasing grasshoppers in a hot parking lot. Their eventual focus on the hindwings ...
Phys.org / Metal–metal bonded molecule achieves stable spin qubit state, opening path toward quantum computing materials
Researchers at Kumamoto University, in collaboration with colleagues in South Korea and Taiwan, have discovered that a unique cobalt-based molecule with metal–metal bonds can function as a spin quantum bit (spin qubit)—a ...
Phys.org / Marine pollutants disrupt cellular energy production in seabirds
Common pollutants are disrupting energy production at the cellular level in wild seabirds, potentially affecting fitness, new research reveals. The study, published in Environment & Health, focused on Scopoli's shearwaters ...
Phys.org / Nanoparticles with AI-crafted sensors open paths to at-home cancer screening
Detecting cancer in the earliest stages could dramatically reduce cancer deaths because cancers are usually easier to treat when caught early. To help achieve that goal, MIT and Microsoft researchers are using artificial ...
Medical Xpress / Targeting the immune system could prevent future heart attacks, clinical trial suggests
Cambridge researchers have discovered that an existing therapy which boosts protective immune cells in people who recently had heart attacks reduces blood vessel inflammation and may reduce the likelihood of future heart ...
Phys.org / 'Platypus' objects in the early universe look like stars but behave like galaxies
Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA's James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou's College of Arts and Science ...
Phys.org / Study overturns long-held model of how plants coordinate immune responses
Plants mobilize their immune defenses far earlier than scientists have believed for decades—and through a previously overlooked early signaling mechanism—according to a new study published in Nature Plants.
