Researchers discover tumors inherited by generations of jellyfish-like creatures
Researchers from the CANECEV laboratory, an international collaboration between Deakin University and the University of Montpellier, have observed for the first time the birth of transmissible tumors in freshwater brown hydras—tiny, jellyfish-like.....»»
Extreme polar light environment of the North and South Poles sustains biodiversity, researchers suggest
Researchers working in Finland propose that the unique light environment of the Earth's polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of.....»»
Transforming agriculture from carbon source to sink: Study shows potential of carbon sequestration options
The food system is one of the most significant sources of greenhouse gas emissions on the planet, making the reduction of emissions in this sector a priority for policymakers around the world. IIASA researchers explored the potential of carbon seques.....»»
Educators and parents reveal culture of fear, censorship, and loss of learning opportunities in wake of FL policies
How can a teacher discuss Jim Crow laws without breaking state law? Should a librarian stop ordering books with LGBTQ+ characters? A new white paper by UC San Diego and NYU researchers reveals the experiences of K-12 educators and parents in Florida.....»»
Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»
"Doomsday" glacier set to melt faster and swell seas as world heats up, say scientists
Tidal action on the underside of the Thwaites Glacier in the Antarctic will "inexorably" accelerate melting this century, according to new research by British and American scientists. The researchers warn the faster melting could destabilize the enti.....»»

Saturday Citations: Football metaphors in physics; vets treat adorable baby rhino"s broken leg
This week, researchers reported an effective way to protect working dogs from heat stress: training them to dunk their heads in cool water. A new computational technique provided a breakthrough in understanding the so-called "pseudogap" in quantum ph.....»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
Small "no-take zone" can help protect critically endangered hammerhead shark in Columbia
Researchers are advocating for a "no-take zone" off the coast of Colombia after one of the world's smallest and most threatened hammerhead species was found to do very little traveling outside of a Marine Protected Area in the region......»»
Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
