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 / 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 / Bird guano powered rise of Chincha Kingdom in Peruvian Andes, archaeologists find
New archaeological evidence reveals that seabird guano—nutrient-rich bird droppings—was not only essential to boosting corn yields and supercharging agriculture in ancient Peru, but it may have been a driving force behind ...
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 / 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 / Mars' 'young' volcanoes prove more complex than scientists once thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully understand how volcanoes ...
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 / Twilight fish study reveals unique hybrid eye cells
Researchers have identified a new type of visual cell in deep-sea fish larvae that challenges a century of knowledge about vertebrate visual systems. Dr. Fabio Cortesi from The University of Queensland's School of the Environment ...
Phys.org / Strike against mask wearing in 1930s echoed COVID-19 protests, study finds
New research from The University of Manchester has shown that debates and resistance about wearing face masks go back a lot further than the COVID-19 pandemic. Dr. Meng Zhang, a Wellcome Trust Research Fellow at the University's ...
Dialog / Rethinking climate change: Natural variability, solar forcing, model uncertainties, and policy implications
Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other anthropogenic forcings account for nearly all observed global surface warming—slightly above 1 °C—since ...
Phys.org / A new way to 'cage' plutonium
Plutonium (Pu) exhibits one of the most diverse and complex chemistries of any element in the periodic table. Since its discovery in 1940, scientists have synthesized and studied many different types of plutonium-containing ...
