Phys.org / Invasive aoudad pose deadly risk to native bighorn sheep
An invasive species found across West Texas may pose a greater threat to native bighorn sheep than previously understood.
Medical Xpress / Brain imaging now reveals receptor dysfunction in living patients with schizophrenia
A study using positron emission tomography (PET) imaging has found that patients with schizophrenia had significantly lower muscarinic acetylcholine M1 receptor availability (about 13%–19%) across multiple brain regions than ...
Medical Xpress / Ultrafine air particles may drive 2 million premature deaths each year
Ultrafine particles (UFPs) –smaller than 100 nanometres and invisible to the naked eye—contribute substantially to illness and mortality worldwide. That is the finding of an international study led by researchers at the Max ...
Phys.org / With an eye toward exploration, researchers map moon's regolith thickness
New research by lunar scientists from Brown University provides critical new insights into the thickness of the moon's regolith, the layer of loose dust and rock that drapes the entire lunar surface.
Phys.org / New method brings single-particle quality control to nanocrystal manufacturing
Nanocrystals are already used in millions of devices, including televisions, laptops and displays, and are considered key materials for the next generation of quantum, sensing and solar technologies. However, they have not ...
Tech Xplore / Paintable electrodes could power creative and colorful wearable sensors
Engineers at Penn State are blending art and science to create cute, paint-on tattoos that could help spot heart attacks early, power robotic prosthetics and read brain waves—all within a colorful, customizable system that ...
Phys.org / Can bacteria reveal hidden pollution? New river study says yes
The Guadalquivir is the most important river in Andalusia. Stretching 657 kilometers (408 miles), it forms the backbone of Andalusia, from its source in the Sierra de Cazorla mountains to its mouth in Sanlúcar de Barrameda. ...
Medical Xpress / Impact of overweight on cancer risk may be significantly underestimated
Being overweight and obesity may contribute to significantly more cancer cases than previously thought. This is the conclusion reached by researchers at the German Cancer Research Center (DKFZ). Their analysis shows that ...
Medical Xpress / Study finds smokers are unlikely to smoke more when switching to low-nicotine cigarettes
People who switch to cigarettes with dramatically reduced nicotine levels are unlikely to smoke more cigarettes or inhale more smoke to compensate for the lower nicotine content, according to a new study led by researchers ...
Phys.org / Political representatives found more polarized on climate change than their constituents
It is no surprise that there are political disagreements over climate protection measures. Parties differ in their assessments of which measures they consider effective, fair or economically acceptable. However, the question ...
Phys.org / Saturday Citations: Blue zone longevity; soft tissue find predates dinosaurs; black hole collisions simplified
This week, researchers reported finding nanoplastics in Antarctic soils for the first time, suggesting they were delivered via long-range atmospheric transport. A study associates the use of hormonal birth control with the ...
Phys.org / Low carbon dioxide levels improve microbial production of biodegradable plastic
In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that ...
