Phys.org / Artemis astronauts to shed light on space health risks
While the Artemis II astronauts have been protected from the icy vacuum of space on their journey, their bodies have nonetheless been left exposed to possibly high levels of radiation—a danger of space travel that NASA is ...
Phys.org / Could we actually terraform Mars? A new scientific roadmap lays out the blueprint—and the risks
Reading the "Mars Trilogy" by Kim Stanley Robinson brings the benefits and pitfalls of efforts to terraform the red planet into sharp relief. Since the 1970s, when Carl Sagan first suggested the possibility that we could ...
Phys.org / Parabolic flight test shows lasers can propel graphene aerogels in microgravity
Lasers could one day steer solar sails and adjust a satellite's position in outer space, thanks to graphene. An experiment on a gravity rollercoaster ride showed how this innovative material has the potential to revolutionize ...
Phys.org / The binding sites that guide fungal 'vesicle hitchhiking'—new study maps mRNA transport
A specific protein controls mRNA transport in fungi and distinguishes important from unimportant binding sites in the transported mRNAs. Researchers from Würzburg and Düsseldorf have discovered this mechanism.
Phys.org / Penguins in remote Patagonia are carrying 'forever chemicals' signals
Penguins living along the Patagonian coast of Argentina can serve as living monitors of their environment by using small, chemical-detecting leg bands, according to a study from the University of California, Davis, and the ...
Phys.org / Researchers clarify how cells remove damaged endoplasmic reticulum
The cell's endoplasmic reticulum (ER) plays a central role in protein synthesis, folding, and calcium (Ca²⁺) storage. When damaged, ER-phagy (self-eating) removes affected ER regions via double-membrane vesicles called autophagosomes. ...
Tech Xplore / Deep-tech company develops high-precision passive eye-tracking technology for smart contact lenses
XPANCEO, a deep-tech company developing smart contact lenses, has unveiled a passive eye-tracking system that achieves industry-level measurement precision using standard cameras. The system employs microscopic patterns embedded ...
Phys.org / Knowledge firewalls inside alliance firms may weaken inventions and future breakthroughs
From the Wright brothers' first flight to the speedy development of COVID-19 vaccines, collaboration has been key to innovation. Paradoxically, even competitors can benefit from collaboration—when they hold different pieces ...
Tech Xplore / AI is changing more than your writing—it may be shaping your worldview, say researchers
Use of ChatGPT, Claude and other large language models, or LLMs—what most people call "AI"—has surged since ChatGPT debuted publicly in 2022. Hundreds of millions of people now use these tools weekly, according to recent ...
Medical Xpress / Some common IBS treatments are linked to a higher risk of death, say study
A large, long-term study led by Cedars-Sinai Health Sciences University investigators suggests that some medications commonly prescribed to treat irritable bowel syndrome (IBS)—including antidepressants—may be associated ...
Phys.org / This protein helps cancer cells survive treatment—and points to new treatments
Researchers at Umeå University have contributed new insights into how cancer cells protect themselves from cell death. The study provides a deeper understanding of how key proteins interact within the cell and could, in the ...
Tech Xplore / Solar-powered device disinfects drinking water in under an hour
For many people living in developed nations, towns and cities take care of ensuring that residents' water is clean and safe. Municipalities have advanced filters and UV light disinfection technologies at their disposal. Some ...
