Phys.org / Sharper brains switch to a 'not what you know, but who you know' mindset online and on social media, study shows
Forming social connections online and via social media reduces how much people engage with and learn from the content posted but significantly boosts their networking performance, according to new research. The study, published ...
Phys.org / These monster black holes did not form the usual way—their history of violence is written into spacetime ripples
The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of ...
Phys.org / Team steers electron spin ballistically in graphene
Researchers at The University of Manchester's National Graphene Institute have shown that electrons in ultra-clean graphene can be steered with high precision while keeping their spin information intact, a key requirement ...
Phys.org / How soil bacteria help plants defend themselves against disease
A study led by researchers at the University of Liège reveals the mechanism by which surfactin, a molecule produced by beneficial soil bacteria, activates plants' immune defenses. This mechanism, distinct from the classical ...
Phys.org / LED light unlocks 3D optical fingerprints inside materials without lasers
Researchers have developed, for the first time in the world, incoherent dielectric tensor tomography (iDTT), a technology that can read complex three-dimensional optical fingerprints inside materials using only everyday LED ...
Phys.org / Archaeologists unearth evidence of dogs being traded within Mayan societies
A University of Calgary archaeologist has found evidence that the Classic Period Maya were trading live dogs over long distances between the northern Yucatan peninsula and central Chiapas regions.
Phys.org / Pilot whales are already 'shouting' at full volume, but one busy waterway is pushing them to the edge
With over 60,000 ships passing through the Strait of Gibraltar each year, this stretch between the Atlantic and Mediterranean is one of the busiest waterways on the planet. This narrow strip of water is also home to a critically ...
Phys.org / Thawing Arctic soil awakens only half of soil microbes, new study reveals
As the Arctic warms at an unprecedented rate, frozen soils that have remained locked in ice for most of the year are now thawing for longer periods. Yet new research led by an international team including scientists from ...
Phys.org / Chilean wasp named in honor of Sir David Attenborough's 100th birthday
Scientists from the Natural History Museum, London have described a new genus and species of parasitic wasp found within the Museum's collections, and named it as a birthday present for Sir David Attenborough.
Phys.org / Harmless viruses trap Salmonella on flexible polymer in portable microfluidic sensor
Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding ...
Dialog / Scientists uncover hidden parasite diversity in barb fish from the Sea of Galilee
When most people think about biodiversity in lakes and rivers, they imagine fish, plants, or perhaps birds and amphibians. But beneath the surface exists another world that often goes unnoticed: microscopic parasites that ...
Phys.org / Climate-driven extreme fire danger cannot be prevented by carbon neutrality alone, study warns
A new study warns that unless atmospheric carbon is reduced immediately, future summers will become even hotter and future wildfires even more destructive. A research team led by Professor Seung-Ki Min of the Department of ...
