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 ...
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 ...
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 ...
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 ...
Phys.org / Hybrid bioprinter creates capillary networks narrower than 10 micrometers
More than 100,000 people are awaiting an organ transplant in the United States, with a new candidate added to the list every 10 minutes. Even if the transplant is carried out successfully, recipients must take immunosuppressive ...
Phys.org / Spontaneous magnons synchronize with external signals at room temperature
Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient ...
Phys.org / Radiation vest tested on NASA moonshot can cut astronauts' exposure in solar storms, study suggests
A new study suggests a protective vest tested on a manikin during NASA's first Artemis moonshot could drastically cut the radiation exposure of lunar astronauts during severe solar storms.
Phys.org / Chemical fingerprints reveal hidden binary pasts of massive stars
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, ...
Phys.org / Californians are twice as likely as Louisianans to be childfree—but demographics tell more of the story
Across the United States, the number of people who do not have and do not want to have children is growing. While they are twice as likely to live in California as Louisiana, individual demographic characteristics are the ...
Phys.org / What happens to nanoparticles when they enter the bloodstream?
The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. ...
