Medical Xpress / Air-sampling tunnel reveals major person-to-person differences in release of infectious virus
A study published in the journal Cell provides the clearest evidence to date that people infected with influenza actively expel infectious virus into the air and that the amount released varies enormously between individuals.
Phys.org / Why Americans think they won't benefit from Social Security
Social Security's trust funds are projected to run out by 2035, but that doesn't mean retirees will be left with nothing. New research from the Cornell SC Johnson College of Business reveals that most Americans misinterpret ...
Phys.org / CERN hails delicate test on transporting antimatter as a scientific success
Scientists in Geneva took some antiprotons out for a spin—a very delicate one—in a truck, in a never-tried-before test drive that has been deemed a success.
Tech Xplore / Study finds AI privacy leaks hinge on a few high-impact neural network weights
Researchers have discovered that some of the elements of AI neural networks that contribute to data-privacy vulnerabilities are also key to the performance of those models. The researchers used this new information to develop ...
Phys.org / Snow flies produce bursts of heat and proteins to avoid freezing, new study finds
In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling ...
Tech Xplore / Thousands of pico-satellites may transform how phones connect to space
Swarms of pico-satellites could work together as a single large antenna for direct-to-smartphone communications, as reported by researchers from Japan. Instead of relying on a single large satellite with a phased-array antenna, ...
Medical Xpress / Touch and temperature: How special fats fine-tune our senses
Our ability to feel a harmful touch or sense dangerous heat relies on specialized receptor proteins embedded in nerve cell membranes. But how do these receptors maintain their exquisite sensitivity? In a new study, researchers ...
Medical Xpress / Well-fed penguins live longer but age faster—much like modern humans
In public discourse, the increasing lifespan in Western countries is often linked to longer life in good health. However, studying human aging in modern societies is complex because outcomes are shaped by numerous social, ...
Phys.org / Preparing for the next pandemic: Scientists discover a new class of influenza antivirals
Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings ...
Tech Xplore / LLMs and creativity: AI responses show less variety than human ones
Can using a large language model (LLM) make a person more creative? Prior work has shown that using LLMs can make creative outputs more homogeneous, but this homogenization could stem from the specific LLM used or from widespread ...
Medical Xpress / Is lighter sleep a normal part of aging, or a sign of something more serious?
As you get older, it's normal to notice changes in your sleep. These can include fewer hours of shuteye, waking up more during the night, and finding it harder to drop off. However, despite the general view that older people ...
Medical Xpress / PP4 protein stops the body from overreacting to severe infection, scientists discover
When someone gets a bad infection, the body's immune system rushes in to fight the germs. But sometimes this defense system becomes too strong and starts hurting the person's own tissues and organs. This condition, known ...
