Phys.org / Space travel doesn't affect the strength of heart muscle cells, study finds
It's common to see images of astronauts on the International Space Station exercising, running on special treadmills and pedaling cycles designed for tight quarters.
Phys.org / Genetic switch could help tomatoes produce fruit in cold weather
Every tomato begins with a flower. But before a fruit can grow, an intricate sequence of events must happen in perfect order. The flower's male and female organs must develop together, pollen must be released at exactly the ...
Phys.org / DNA research highlights the genetic vulnerability of Asian elephants
The DNA of Asian elephants tells a concerning story. Although all four subspecies are under pressure, there are considerable differences in their genetic health. In an article published in the journal Genome Biology and Evolution, ...
Phys.org / Single synthetic peptide forms electrically polarized, self-healing hydrogel
Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) and RIKEN Pioneering Research Institute (PRI) in Japan, together with collaborators from the University of Münster, Germany, have developed a new hydrogel ...
Medical Xpress / Sweat sensor enables continuous noninvasive measurement of cholesterol
If you see a doctor regularly, chances are you have had a lipid panel ordered and your blood drawn at a lab. The results told your physician your levels of cholesterol and triglycerides, factors that play a role in diagnosing ...
Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Medical Xpress / Epidural may help turn breech babies, reducing need for C-section
Women carrying breech babies have a better chance of avoiding a cesarean delivery (C-section) when spinal or epidural anesthesia is used during external cephalic version (ECV), a procedure used to turn the baby head-down ...
Phys.org / Graphene nanowrinkles could reshape electricity in future ultrathin devices
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity, a phenomenon in which a material generates an electric charge ...
Phys.org / Microbes turn CO₂ into protein and vitamin B9 at commercially viable prices
Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing ...
Medical Xpress / Cancer protein p53 observed in action reveals more order than expected
Cancer occurs when cells divide uncontrollably and displace healthy cells. Tumor suppressors provide an important defense against this. As molecular growth inhibitors, they prevent healthy cells from becoming cancerous. A ...
Phys.org / Claim that science is becoming less disruptive challenged after years-long publication delay
A widely cited Nature cover article from 2023 claimed that scientific innovation has significantly declined in recent decades. This finding was based on a citation analysis of large sets of metadata concerning scientific ...
Tech Xplore / Extending AI architectures to address continuous scientific problems
Artificial intelligence is proving to be transformative in its ability to work with language and images. Now, with a growing push to apply AI to scientific discovery, Caltech's Anima Anandkumar says there is a crucial ingredient ...
