Phys.org / One-step method reveals structures of RNA-protein complexes in living cells
A new method developed at Baylor College of Medicine and collaborating institutions allows researchers to better understand how RNA works. The method, published in Molecular Cell, is a powerful strategy for identifying intricate ...
Phys.org / Rose pangenome maps 55,000 genes, opening new path for breeding
Roses are among the most economically significant ornamental plants worldwide, with widespread applications in the cut flowers, garden, and cosmetics industries. Yet fewer than 10% of rose species have contributed to modern ...
Phys.org / AI maps mammals' molecular 'dark matter' by predicting billions of missing metabolites
Invisible "dark matter"—what cosmologists call the mysterious glue that holds everything together—is estimated to make up more than a quarter of the universe. In chemistry, dark matter refers to the thousands of small molecules ...
Phys.org / ATLAS acts as a cosmic-ray laboratory with first measurement of proton–oxygen collisions
Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating showers of energetic secondary particles that rain down from the sky. Approximately one of these ...
Phys.org / AI tool predicts how new drug molecules move before costly lab tests
For every life-changing new drug that comes to market, many candidates fail along the way. An artificial intelligence-based tool developed at the University of Oregon could help scientists better predict how hypothetical ...
Phys.org / Breaking a shared defense restores antibiotics against two cystic fibrosis lung bacteria
A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise ...
Phys.org / Bacteria's 'two-way door' revealed: How antimicrobials cross cell membranes
Researchers at Durham have helped unlock a new understanding of how bacteria import antimicrobial peptides—the molecules that can kill or inhibit microbes. The research sheds new light on SbmA, a key transporter protein found ...
Phys.org / Mosses and thale cress share the same leaf growth principles, despite 400 million years of separate evolution
A study published in Science Advances shows that, in moss and the model plant Arabidopsis thaliana, commonly known as thale cress, leaf formation relies on very similar cellular dynamics, with growth concentrated at their ...
Phys.org / Water-based process could make compostable packaging practical at industrial speeds
About 30% of plastics consumed are made to last forever but are discarded after a single use. Researchers at Virginia Tech are working to change that with a new approach that could make environmentally responsible packaging ...
Phys.org / World's largest collection of Olympiad-level math problems now available to everyone
Every year, the countries competing in the International Mathematical Olympiad arrive with a booklet of their best, most original problems. Those booklets get shared among delegations, then quietly disappear. No one had ever ...
Phys.org / Disabled parrot is undefeated alpha male of his group thanks to novel 'beak jousting'
A study reported in Current Biology shows how physical disabilities in the animal world can be overcome through behavioral innovation. The report features an endangered kea parrot in captivity at New Zealand's Willowbank ...
Phys.org / Finding a hidden highland culture in the mountains of southern Georgia
Archaeologists are unearthing evidence of long-term human occupation in the mountains of the Republic of Georgia. A new paper published in the journal Antiquity reports on eight years of digging on the Javakheti Plateau, ...
