Phys.org / Astrophysicists test a new piece of the sky to probe dark matter and dark energy
In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy. Exactly what these dark components are remains a mystery, but they have a tremendous impact on our ...
Phys.org / The microbiome of an entire country mapped for the first time
An international research team led by Aalborg University with contributions from the University of Vienna has systematically mapped the microbiome of an entire country for the first time. In the study "Microflora Danica," ...
Phys.org / Fearless frogs feast on deadly hornets
A remarkable resistance to venom has been discovered in a frog that feasts on hornets despite their deadly stingers. This frog could potentially serve as a model organism for studies on mechanisms underlying venom tolerance.
Phys.org / LHC data confirm validity of new model of hadron production—and test foundations of quantum mechanics
A boiling sea of quarks and gluons, including virtual ones—this is how we can imagine the main phase of high-energy proton collisions. It would seem that particles here have significantly more opportunities to evolve than ...
Phys.org / New study challenges the idea of humans as innately nature-loving
Nature is a source of well-being and recovery for many people. However, research shows that there is also a growing number of individuals who experience negative emotions, such as fear, discomfort, or even disgust, toward ...
Phys.org / Lightning channels reveal hidden bursts: Lateral negative re-discharges observed for first time
A new study led by researchers from the Institute of Atmospheric Physics of the Chinese Academy of Sciences (CAS) has uncovered the first observational evidence of lateral negative re-discharges occurring on negative leader ...
Phys.org / Scientists capture first detailed look inside droplet-like structures of compacted DNA
Inside human cells, biology has pulled off the ultimate packing job, figuring out how to fit six feet of DNA into a nucleus about one-tenth as wide as a human hair while making sure the all-important molecules can still function.
Phys.org / Space debris poses growing threat, but new study suggests cleanup is feasible
High up in Earth's orbit, millions of human-made objects large and small are flying at speeds of over 15,000 miles per hour. The objects, which range from inactive satellites to fragments of equipment resulting from explosions ...
Phys.org / Nanotyrannus was not a juvenile T. rex, new study confirms
For decades, paleontologists argued over the lone skull used to establish the distinct species Nanotyrannus. Was it truly a separate species or simply a juvenile Tyrannosaurus rex? A new paper published in Science has definitively ...
Phys.org / How volcanic eruptions set off a chain of events that brought the Black Death to Europe
Clues contained in tree rings have identified mid-14th-century volcanic activity as the first domino to fall in a sequence that led to the devastation of the Black Death in Europe.
Phys.org / Seeding jet exhaust with ice-nucleating particles could reduce aviation's climate impact
If you look up at the sky on a clear day, chances are you'll notice thin, white clouds—also known as contrails—following behind airplanes.
Phys.org / 'Free-range' dinosaur parenting may have created surprisingly diverse ancient ecosystems
Picture a baby Brachiosaurus the size of a golden retriever, hunting for food with its siblings while dodging predators that would happily eat it. Meanwhile, its parents—towering over 40 feet tall—are dozens of miles ...
