Phys.org / Ultrafast light pulses make molecules rotate on quantum materials
Researchers from Germany, Japan and India, led by scientists from DESY and the Universities of Kiel and Hamburg, have found a way to collectively make molecules on a flat surface rotate by exposing them to light using ultrafast ...
Phys.org / Physical activity is linked to the health of the planet, according to a trio of recent studies
Global levels of physical activity have not improved over the past two decades, despite widespread policy development and adoption, and large disparities persist across gender and socioeconomic groups. The findings from three ...
Phys.org / U.S. Indigenous peoples experience higher rates of fatal police violence in and around reservations
Indigenous people in the United States are at higher risk of fatal police violence in and around American Indian/Alaska Native (AIAN) reservations, according to the first comprehensive national study on the subject from researchers ...
Phys.org / Pathogenic virus infects and structurally reorganizes human cells, finds new study
Orthohantaviruses, such as the Puumala virus, are widespread in Europe, causing flu-like illnesses and severe kidney damage in those infected. It is increasingly considered a zoonotic threat. Researchers from the Medical ...
Phys.org / Key protein SYFO2 enables 'self-fertilization' of leguminous plants
Most plants allow fungal microorganisms to enter their root cells and provide them with carbohydrates in exchange for a better supply of nutrients and water. Only leguminous plants like peas, beans, and clover enter into ...
Phys.org / Unlocking the hidden pocket on a billion‑dollar drug target
For years, a protein inside our cells has quietly powered billions of dollars' worth of cancer drugs. Now a team of researchers have discovered that this workhorse protein, called cereblon, in addition to its known functions, ...
Phys.org / Microbes hitchhiking on marine snow could limit how deep carbon sinks
In some parts of the deep ocean, it can look like it's snowing. This "marine snow" is the dust and detritus that organisms slough off as they die and decompose. Marine snow can fall several kilometers to the deepest parts ...
Phys.org / Gene edit makes probiotic safer for immunocompromised patients
An international team of researchers has modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found that the modified yeast is less likely to ...
Phys.org / Scientists trace crop viruses back to the last Ice Age
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. According to a new international study published in Plant Disease, the ancestors ...
Phys.org / AI disclosure labels may do more harm than good, study warns
The growing use of AI-generated scientific and science-related content, especially on social media, raises important concerns: these texts may contain false or highly persuasive information that is difficult for users to ...
Phys.org / Ocean carbon removal looks promising, but nutrient cycling could curb long-term gains
There is growing interest in the scientific community and private sector in biological approaches to marine carbon dioxide removal—strategies designed to enhance the ocean's natural ability to absorb carbon from the atmosphere. ...
Phys.org / From carp to crocodilians: Why deliberately introduced freshwater giants may bring hidden risks
More than 40% of extant large freshwater animals (megafauna), including carp, salmonids, crocodilians, turtles, beavers, and hippopotamuses, have been deliberately introduced outside their natural range, often for economic ...
