Phys.org / Frequency comb lasers enable clearer observation of black holes
Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies. To observe distant black holes clearly, multiple radio telescopes must capture cosmic signals ...
Phys.org / Increased deciduous tree dominance reduces wildfire carbon losses in boreal forests, study shows
As climate change drives more frequent and severe wildfires across boreal forests in Alaska and northwestern Canada, scientists are asking a critical question: Will these ecosystems continue to store carbon or become a growing ...
Phys.org / Physics of foam strangely resembles AI training
Foams are everywhere: soap suds, shaving cream, whipped toppings and food emulsions like mayonnaise. For decades, scientists believed that foams behave like glass, their microscopic components trapped in static, disordered ...
Medical Xpress / The FDA unveils a new food pyramid that promotes red meat and protein
For years, the federal government advised Americans to limit red meat and foods high in saturated fats. However, new federal dietary guidelines elevate protein, dairy and healthy fats to the top of a redesigned food pyramid—a ...
Phys.org / Neutral-atom arrays, a rapidly emerging quantum computing platform, get a boost from researchers
For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian Will and Nanfang Yu have ...
Phys.org / Neutral stances on hot topics can damage your reputation, study finds
People shouldn't be afraid to say what they think, and new research from the University of Virginia bears that out.
Phys.org / How mountain terraces have helped Indigenous peoples live with climate uncertainty
Indigenous communities have lived with changes to the climate for centuries. Their adaptations over those many years are based on their close observation of weather, water, soils and seasonal change, and they have been refined ...
Phys.org / Chemist proposes shared 'model proteins' to improve reproducibility in protein science
Protein scientists could improve reproducibility and coordination across the field by rallying around a small, shared set of "model proteins," according to a new Perspective by Connecticut College chemist Marc Zimmer.
Phys.org / Comprehensive map reveals how E3 ligases organize protein cleanup in human cells
Maintaining cellular order is a major logistical challenge: Individual mammalian cells contain billions of protein molecules, which must be synthesized, deployed, and removed with precision. In the ubiquitin-proteasome system ...
Medical Xpress / Extremely elevated lipoprotein(a) levels tied to 30-year heart risk in women
Brigham and Women's Hospital investigators link very high lipoprotein(a) with a higher 30-year risk of major cardiovascular events in initially healthy women.
Phys.org / How cells stay healthy: New insights into a selective protein cleanup system
To stay healthy, our cells rely on a self-cleaning mechanism that removes defective or unnecessary components. This process, known as autophagy, has been linked not only to cellular maintenance but also to various diseases ...
Tech Xplore / Sub-zero green freezer achieves zero emissions
Researchers at the School of Engineering of The Hong Kong University of Science and Technology (HKUST) have developed the world's first sub-zero Celsius elastocaloric freezing device, capable of reaching temperatures as low ...
