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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 / Mira A ejects seven Earth masses, forming a heart-shaped cloud 300 light-years away
Just in time for Valentine's Day, space offers a heart-shaped greeting. The star Mira A, about 300 light-years from Earth, has released material into an expanding cloud of gas and dust resembling a heart. Both the amount ...
Phys.org / Extinct Hawaiian ibis with strangely small eyes suggests a shift to nocturnal life
Islands are famous for producing some of the world's strangest creatures, and now a new international study shows that the evolution of bird species on Hawaiian islands includes an ibis with unusually small eyes and limited ...
Phys.org / New lithium-based green phosphors rival today's commercial LED standard
Research results from Innsbruck, Schwabmünchen, and Düsseldorf demonstrate how the most widely used green phosphors in commercial LEDs can be replaced by representatives of an entirely new class of compounds. Green luminescence, ...
