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 / 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 / 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 / Pesticides make Argentine ants go crazy, sending them roaming or clustering before workers die
Don't assume an uptick in ant activity after setting out pesticide traps means the treatment failed. New UC Riverside research shows their behavior changes as chemicals make their way through a colony.
Phys.org / Red blood cells inspire next-generation therapeutic nanocarriers
Red blood cells serve as the foundation for nanocarriers that show promise in a new study as effective and efficient vehicles for gene therapy, tumor targeting and other medical treatments. Scientists at The Ohio State University ...
Phys.org / Can computers learn what makes the most iconic jazz musicians stand out?
Machine learning models can identify jazz pianists from recordings and reveal the musical "fingerprints" that make individual performers recognizable, according to a study investigating 20 famous jazz pianists. The research, ...
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 / 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 / Molecular electromagnetic sensor may enable remote-controlled gene therapy
The deoxyribonucleic acid (DNA) of living organisms contains regulatory elements that control when, where and to what extent specific genes are turned on or off. They can be co-opted to create "gene switches" that hold significant ...
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 / 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 / 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 ...
