Phys.org / Geoengineering could protect Amazon rainforest from climate change
Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby ...
Medical Xpress / Heavy drinking takes toll on college students' cognition, study finds
When college students drink very heavily or to the point of blacking out, they're more likely to report poorer cognitive functioning the next day, like forgetting someone's name or having trouble making decisions, according ...
Medical Xpress / Calcium surges in brain immune cells may switch anxiety on and off
Researchers had previously discovered a population of immune cells within the brain that can act as accelerators and brakes for anxiety in mice. Now, new research from the lab of Mario Capecchi, Ph.D., professor of human ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
Phys.org / Photonic chip generates milliwatt-level UV light, 100 times brighter than before
Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the first time, the technique ...
Medical Xpress / E. coli and 'good' bacteria are balanced by breast milk in baby gut microbiomes
Sugars contained exclusively in breast milk are helping to feed an important balance of bacteria in babies' developing gut microbiomes, a new study has found. In a paper published in Nature Communications, a European research ...
Medical Xpress / Emerging procedure reduces circulation concerns by 50% in patients with no-option chronic limb-threatening ischemia
Data from the PROMISE III trial suggest that chronic limb-threatening ischemia (CLTI) patients with no other treatment options experienced significant quality of life (QoL) improvements after undergoing transcatheter arterialization ...
Phys.org / Reeds boost mosquito spread in rivers and ponds
Reed, an invasive alien plant that is abundant on the banks of many rivers, ponds and canals, can encourage the growth of common mosquito populations in the absence of natural predators. When the plant's litter accumulates, ...
Tech Xplore / This simple solar cell manufacturing tweak could solve perovskites' biggest weakness
A technique that improves the performance and stability of next-generation solar cells—without adding any chemicals or coatings—has been demonstrated by researchers from Korea University and the University of Surrey.
Phys.org / What's in a name? Study finds two dahlia-damaging viruses are variants of same species
For decades, two different viruses were believed to be responsible for a common, untreatable disease in dahlias, a colorful, high-value flower grown worldwide. Virologists at Washington State University have now learned that ...
Phys.org / Sun simulations reveal how cool prominences survive in million-degree corona
At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge structures of significantly cooler solar plasma—about 10,000 degrees—appear within the corona. ...
Phys.org / Collagen analysis finds wider prey use by Neanderthals and modern humans
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has taken part in a study published in the International Journal of Osteoarchaeology that provides new insights into subsistence strategies during the ...
