Phys.org / Observations since 1850 reveal regional climate fingerprints of human-induced warming
There is no question that the current global temperature increase is human-caused. Global warming has long since emerged as the dominant signal amid natural climate fluctuations. However, identifying how this warming manifests ...
Phys.org / How plants selectively silence jumping genes while protecting essential ones
Histone variants help establish DNA methylation at transposons (jumping genes) while preventing this epigenetic modification from spreading to essential genes in plants, a study from the Institute of Science Tokyo reveals. ...
Phys.org / Locust neurons detect PFAS at environmentally relevant levels, pointing to portable sensors
Researchers at Michigan State University have discovered that neurons in a locust's brain can distinguish among multiple PFAS compounds, including PFOS, one of the world's most common "forever chemicals," at environmentally ...
Phys.org / Last common ancestor of humans and chimpanzees could have been a vertical climber, no matter its feet
New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Phys.org / First pair of feeding supermassive black holes found in a Green Pea galaxy
Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations ...
Phys.org / Hubble solves merger mystery from Milky Way's early years
Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from NASA's Hubble Space Telescope show definitive evidence of a dwarf galaxy merging with the young Milky Way ...
Phys.org / Unlocking Gondwana's 120-million-year archive: Karoo record refines timing of extinctions and climate upheavals
A new review led by professor Emese Bordy at the University of Cape Town (UCT) Department of Geological Sciences brings together more than two decades of research on the Karoo Supergroup, revealing how scientific understanding ...
Phys.org / Breath-strip-like nanofiber film delivers three pain drugs in under two seconds
Children and seniors who have difficulty chewing and swallowing conventional tablets may have an easier way to find pain relief. Cornell researchers have developed an ultrafast-dissolving nanofiber film that can deliver a ...
Phys.org / Ancient Austronesian seafarers carried symbolic art 4,000 years ago
A 4,000-year-old painted stone plaque discovered on a remote Indonesian island is the first known example of portable art belonging to the Austronesian Painting Tradition (APT), providing a rare glimpse into the symbolic ...
Phys.org / A weakening Atlantic Ocean current system could accelerate Earth's warming
A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found.
Phys.org / Tiny feet on cells can sense defects and stall migration to heal wounds
Cells travel through the body both individually and in collective groups during development, wound healing and diseases such as cancer. New research from the McKelvey School of Engineering at Washington University in St. ...
Medical Xpress / Experimental pill targets nerve pain pathway, cutting opioid use after abdominal surgery
Opioids can be highly effective at relieving moderate to severe pain, whether it comes from surgery, an injury or conditions such as cancer. They work by activating opioid receptors in the brain and body, which block pain ...
