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 / 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 ...
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 / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Phys.org / Europe's worst medieval flood highlights risk of successive extreme events
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
Phys.org / New frog species discovered in the Amazon's flooded forests
Scientists from Brazil and other countries have discovered a new species of frog in the flooded forests of the western Amazon. They named it Adenomera varcena. This finding significantly advances our understanding of Amazonian ...
Phys.org / AI tool could help veterinarians track heart disease more precisely
For dogs with heart disease, a fraction of a centimeter can make a life-changing difference. Veterinarians often rely on chest radiographs to monitor subtle changes in heart size that help determine when treatment should ...
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 / 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 ...
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 / History, not age, determines the genomic importance of ancient trees
Ancient trees—those that are remarkably old for their species—are declining worldwide, raising concerns about the loss of the ecological and evolutionary history they represent. Their exceptional longevity has long encouraged ...
