Phys.org / Fiber-optic cables detect silent whales off Svalbard by tracking pressure waves
A 100-year-old equation and a fiber-optic cable off the coast of Svalbard led researchers to discover they could detect swimming whales—even if they were completely silent. The discovery broadens the tools biologists could ...
Phys.org / Why Ho Chi Minh City's pollution sources may have been misread for years
Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution ...
Phys.org / Morocco's hidden history: Archaeology, DNA and carbon dating rewrite the story of the ancient world
For decades, stories about the ancient Mediterranean have centered on the grand cultures of Greece, Rome, Phoenicia and Egypt. Northwest Africa seldom enters the picture before the arrival of Phoenician traders on the Moroccan ...
Phys.org / Hidden dark force may slow cosmic structure growth, not speed it up
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Phys.org / Mathematical modeling helps advance use of magnetic particles in targeted drug-delivery systems
A Florida State University computational scientist is paving the way for future medical breakthroughs by developing mathematical models and simulations to predict the behavior of a unique drug-delivery method, which aims ...
Phys.org / Pseudomonads boost crop growth in salty soils across multiple plants, could protect against rising sea levels
Researchers at the University of East Anglia have helped uncover a hidden ally in the fight against one of agriculture's greatest threats—salty soil. Led by Chinese collaborator Dr. Yanfen Zheng, the team's new study shows ...
Phys.org / Greece says preparing 'historic' ISS space mission
Greece is planning "a first historic mission" to send a Greek astronaut to the International Space Station, Prime Minister Kyriakos Mitsotakis' office announced Friday.
Phys.org / People care more about being right than avoiding mistakes, study finds
Conventional wisdom says the best predictions are the ones that minimize mistakes, but new research suggests that is not necessarily how people see it. A study published in Management Science has found that when people make ...
Phys.org / Wave-packet interferometry captures elusive dark excitons in organic superconductor
In a recent study, Manish Garg, independent group leader at Max Planck Institute for Solid State Research (MPI FKF), succeeded in probing the local properties of bright and dark excitons in the organic superconductor copper ...
Phys.org / Ultrafast X-rays allow researchers to 'watch' how molecules rearrange during a chemical reaction controlled by light
Since the 1980s, researchers have sought to use laser light to control chemical reactions relevant to photochemistry, catalysis and light-responsive materials. But this technique, known as coherent control, has a blind spot: ...
Tech Xplore / Safer lithium-ion batteries move closer as 3D-printed cobalt-free electrodes boost power
Since the early 2000s, lithium-ion (Li-ion) batteries have become the predominant rechargeable power source for many mobile devices, electric vehicles, renewable-energy storage grids and more. But the Li-ion batteries in ...
Medical Xpress / Hearing aid use linked to 23% lower dementia risk in people with both epilepsy and hearing loss
Adults with both epilepsy and hearing loss who use hearing aids may have a 23% lower risk of developing dementia than those who do not, according to new research presented at the European Academy of Neurology (EAN) Congress ...
