Phys.org / Indigenous Australian population was much larger than previously thought and decimated after First Fleet's arrival
Australia had a much larger Indigenous population before the arrival of Europeans than previously thought, according to new research. The research also demonstrates much larger population losses resulting from colonization ...
Phys.org / Responsibilities in close social relationships explain Eastern–Western cultural differences
Do you think that a person who reorganizes their life so that their aging parents can live with them would be likely to push another out of the way on the subway? What about greeting strangers with a smile? The answers to ...
Phys.org / Rivers may be carrying more microplastics into the world's oceans than previously thought
Microplastics are a modern environmental menace and a potential threat to human health. These tiny pieces of plastic, measuring from 1 to 5,000 micrometers, come mainly from larger plastics as well as sources such as paints ...
Phys.org / Ultracold cesium atoms reveal Bethe strings predicted nearly a century ago
In 1931, physicist Hans Bethe predicted that, in certain one-dimensional quantum systems, particles can bind together to form multi-particle states known as Bethe strings. Unlike ordinary molecules, which are held together ...
Phys.org / How prehistoric coastal flooding shaped the Northern Adriatic
Researchers have shown how dramatic sea-level rise over a 5,000-year period profoundly changed the coasts of northern Italy, Slovenia and northern Croatia. Successive shaping and reshaping of coastal features influenced the ...
Phys.org / The surprising history of woolly rhinos: They weren't always creatures of the frozen north
Woolly rhinoceroses (Coelodonta antiquitatis) were fascinating creatures: giant, lumbering Ice Age beasts with thick fur and massive horns that died out about 11,000 years ago. Previous genetic studies had left open the question ...
Phys.org / Bizarre galactic radio source remains active for two decades with no detectable X-rays
Astronomers have identified a peculiar radio transient in the Milky Way that has remained active for more than two decades, defying the behavior expected of known classes of galactic radio sources. The paper posted to the ...
Phys.org / Tough vehicle and construction plastics dissolve into reusable material with low-waste method
A new recycling technique could help tackle a major challenge: breaking down some of the toughest plastics without generating large amounts of waste.
Phys.org / First confirmed Diplodocus outside North America reshapes Late Jurassic migration picture
In a discovery that challenges our understanding of dinosaur distribution during the Late Jurassic period, paleontologists have identified the first evidence of the iconic Diplodocus outside North America.
Phys.org / New light-emitting nanoparticles can detect subtle chemical differences
A team of researchers from University of Toronto Engineering has created a new type of dye-sensitized nanoparticle that can detect target chemicals at very low concentrations while also distinguishing between molecules with ...
Phys.org / Speedy electrons for brilliant laser light: Research paves the way for compact, inexpensive free-electron lasers
Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user ...
Phys.org / Room-temperature skyrmion-based synapses could pave the way for energy-efficient AI
Artificial intelligence is transforming how information is generated, processed and stored, but its rapid expansion is also driving unprecedented demand for computing power and electricity. Developing hardware that can process ...
