Phys.org / Lethal virus hits last rare blue macaws in Brazil wild
The only wild specimens of a rare blue parrot which had only recently been returned to its natural habitat in Brazil have been diagnosed with a lethal, incurable virus, the government said in a statement sent to AFP Thursday.
Medical Xpress / Inhibiting a master regulator of aging regenerates joint cartilage in mice
An injection that blocks the activity of a protein involved in aging reverses naturally occurring cartilage loss in the knee joints of old mice, a Stanford Medicine-led study has found. The treatment also prevented the development ...
Medical Xpress / Bird flu viruses are resistant to fever, making them a major threat to humans
Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body's ways of stopping viruses in their tracks, according to new research led by the universities ...
Phys.org / Social media research tool can lower political temperature—it could also lead to more user control over algorithms
A new tool shows it is possible to turn down the partisan rancor in an X feed—without removing political posts and without the direct cooperation of the platform.
Medical Xpress / COVID lockdown linked to increase in early child development issues
Lockdown and social distancing measures during the COVID-19 pandemic were associated with increased developmental concerns about young children in Scotland, research suggests.
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Phys.org / Watching metal crystals grow inside liquid metal: Imaging technique could boost hydrogen production
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
Tech Xplore / New insight into why LLMs are not great at cracking passwords
Large language models (LLMs), such as the model underpinning the functioning of OpenAI's conversational platform ChatGPT, have proved to perform well on various language-related and coding tasks. Some computer scientists ...
Phys.org / Survey raises estimate of African forest elephant numbers
DNA pulled from the dung of African forest elephants has given experts a more accurate—and higher—population estimate for the elusive animal, but the species remains critically endangered, a study showed Thursday.
Medical Xpress / Prototype device restores lost smell by teaching the brain to feel odors
There is new hope for people who have lost their smell. Scientists have successfully tested a breakthrough device that lets people detect the presence of certain odors. This innovative system helps them "smell" again by translating ...
Phys.org / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
