Phys.org / NOvA maps neutrino oscillations over 500 miles with 10 years of data
Neutrinos are very small, neutral subatomic particles that rarely interact with ordinary matter and are thus sometimes referred to as ghost particles. There are three known types (i.e., flavors) of neutrinos, dubbed muon, ...
Phys.org / Ammonia leaks can be spotted in under two seconds using new alveoli-inspired droplet sensor
Researchers from Guangxi University, China have developed a new gas sensor that detects ammonia with a record speed of 1.4 seconds. The sensor's design mimics the structure of alveoli—the tiny air sacs in human lungs—while ...
Phys.org / Ancient DNA suggests hunter-gatherers in Europe's lowlands endured until 2500 BCE
Researchers at the University of Huddersfield have used ancient DNA to reveal that hunter-gatherers in one part of Europe survived for thousands of years longer than anywhere else on the continent—and have uncovered the ...
Phys.org / Subaru observations suggest an intrinsic gap in NGC 5466's tidal stream
Astronomers from the National Astronomical Observatory of Japan (NAOJ) and elsewhere have used the Subaru Telescope to perform deep imaging observations of a distant globular cluster known as NGC 5466. The observational campaign ...
Phys.org / 7,000-year-old deer antler headdress from Eilsleben illustrates contact between hunter–gatherers and early farmers
Central Germany is among the regions where, as early as the mid-6th millennium BC, farmers displaced the Mesolithic hunter–gatherers from the fertile loess soils. Soon after this migration, however, exchange began between ...
Phys.org / How often do people feel passionate love? Study finds about two lifetime loves
Falling passionately in love is one of the most talked about human experiences, celebrated in songs, movies, literature, and art across cultures. Passionate love is widely considered a hallmark of romantic relationships and ...
Phys.org / Saturn's moon Titan could have formed in a merger of two old moons
Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of Saturn, the discoveries ...
Phys.org / Carbon nanotube 'sandpaper' polishes semiconductor surfaces down to a few atoms
The performance and stability of smartphones and artificial intelligence (AI) services depend on how uniformly and precisely semiconductor surfaces are processed. KAIST researchers have expanded the concept of everyday "sandpaper" ...
Phys.org / A familiar magnet gets stranger: Why cobalt's topological states could matter for spintronics
The element cobalt is considered a typical ferromagnet with no further secrets. However, an international team led by HZB researcher Dr. Jaime Sánchez-Barriga has now uncovered complex topological features in its electronic ...
Phys.org / 7,000 years of change: How humans reshaped Caribbean coral reef food chains
Human activity has lessened the resilience of modern coral reefs by restricting the food-fueled energy flow that moves through the food chains of these critical ecosystems, reports an international team of researchers in ...
Phys.org / What honey bee brain chemistry tells us about human learning
A multi-institutional team of researchers led by Virginia Tech's Fralin Biomedical Research Institute at VTC has for the first time identified specific patterns of brain chemical activity that predict how quickly individual ...
Phys.org / Cell division spindles self-organize like active liquid crystals—a theory that holds up
When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto chromosomes (where DNA is stored) ...
