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. ...
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 / Graphene device measures fractional electric charges carried by some of quantum physics' strangest objects
An electron is supposed to be indivisible. It carries one fundamental unit of electric charge, and every electron is exactly the same. But under extreme conditions, large numbers of electrons act together and give rise to ...
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 / Brazil's vast coastline could help address food insecurity through sustainable seafood
New research into seafood consumption and production in Brazil highlights how one of the world's most populous countries could build healthier and more sustainable food systems by encouraging people to eat more seafood, developing ...
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 / Stellar explosions come into focus with new nuclear reaction measurements
In two separate papers published in Physical Review Letters, researchers investigated the nuclear reactions that take place inside supernovae and X-ray bursts—two of the universe's most powerful explosions. Together, the ...
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 / 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 / World off-track on nearly every food system goal, latest assessment reveals
The latest study from the Food Systems Countdown Initiative (FSCI) reveals the stark reality of where global food systems transformation stands: for most indicators on health, environment, livelihoods, governance and resilience, ...
Phys.org / Two eyeless shrimp-like species found in Japan's groundwater are new to science
Researchers have identified two new species in the genus Bogidiella, small shrimp-like amphipods that live in subterranean aquatic environments, from cave waters on the Ryukyu Islands, a subtropical island chain in southwestern ...
Phys.org / It's not just flowers that help the pollinators. Grass can too.
Bees may be relying on your lawn for their next meal, according to a new study from the University of Georgia.
