Phys.org / Paleontologists challenge use of bone growth rings to age crocodiles, dinosaurs
Do the bones of all Nile crocodiles have the same number of growth marks as their age? And can such growth rings be counted to accurately gauge the age of these reptiles? Is this also an accurate method to use when trying ...
Phys.org / Burned permafrost peatlands release carbon for years after wildfires, researchers find
In the face of climate change, permafrost peatland wildfires could play more of a role in the destructive cycle of global warming, University of Alberta research suggests.
Phys.org / The secret lives of catalysts: How microscopic networks power reactions
Catalysts are essential to modern industry, accelerating reactions used to produce everything from fertilizers and fuels to medicines and hydrogen energy. But until now, scientists could not directly observe how reactions ...
Phys.org / Environmental sampling finds more poultry viruses than bird swabs in live markets
Scientists at Duke-NUS Medical School have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study, published ...
Phys.org / How Japanese red elder plants save two lives with one fruit drop
Japanese red elder plants safeguard their own survival when they drop fruits infested by Heterhelus beetle larvae, as well as the survival of these larvae. A Kobe University study changes the narrative on how a plant and ...
Phys.org / Scientists clock a driving factor in the evolution of error correction
All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to evolve error-correcting ...
Phys.org / Whole-genome study of koalas shows genetic diversity alone can misread extinction risk
A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species. Researchers analyzed whole genomes from hundreds of koalas, finding that populations previously ...
Phys.org / Cleaner water, longer-lasting devices: New benchmark measures electrocatalysis oxidants in real time
From brightly colored textile dyes to persistent pesticides and antibiotics, many modern pollutants dissolved in water—such as Bisphenol A—resist traditional treatment methods. A promising approach uses electricity to ...
Phys.org / Pond-dwelling microalga exposes a parallel track for RNA processing
Biology textbooks explain that cells follow a universal rule when processing gene transcripts to make proteins. Non-coding snippets of RNA are bracketed by a guanine-thymine (GT) nucleotide sequence on one end and an adenine-guanine ...
Phys.org / Piecing together parasitic plant pathways
Genes that play a key role in the formation of an infectious organ used by parasitic plants have been identified by plant scientists at RIKEN. This discovery fills a gap in our understanding of how parasitic plants infect ...
Phys.org / Did the first human ancestor originate in the Balkans? New fossil shows evidence of bipedalism
Walking on two legs has long been considered a milestone in human evolution and one of our most defining characteristics. Until now, researchers assumed that the first humans originated in Africa and that bipedalism developed ...
Phys.org / Astronomers discover TOI-5734 b, a hot sub-Neptune twice Earth's size
Using the Transiting Exoplanet Survey Satellite (TESS) and High Accuracy Radial velocity Planet Searcher for the Northern Hemisphere (HARPS-N), an international team of astronomers has discovered a hot sub-Neptune exoplanet ...
