Phys.org / Introducing ecotech, nature's innovation accelerator
An international research team has developed a roadmap for an emerging field of technology called ecotech, which aims to create scalable solutions to urgent environmental, social and economic challenges. The team describes ...
Phys.org / Urban trees cool the world's cities more than we thought—but we can't rely on them alone
Cities and towns are usually 1–3°C hotter than the surrounding countryside, because asphalt, concrete and brick absorb heat from the sun and radiate it slowly. Some cities can be as much as 7°C hotter. This effect is known ...
Phys.org / New tectonic plate boundary could be forming in Zambia, scientists say
Isotope analysis of gas from geothermal springs in Zambia could show that a new continental rift is forming, scientists say. Unexpectedly high helium isotope ratios indicate that a weakness in Earth's crust has broken through ...
Tech Xplore / Quantum dot emitter delivers near-identical telecom photons at 40 million per second
Quantum technologies, devices that perform specific functions leveraging quantum mechanical effects, could soon outperform their classical counterparts on some tasks. Quantum emitters, devices that release individual particles ...
Phys.org / When uncertainty spikes, chasing rewards backfires and a more informed strategy pulls ahead
Humans and other animals are constantly required to make decisions under uncertain conditions or while in rapidly changing environments. Past psychology and biology studies showed that some decision-making strategies can ...
Medical Xpress / How the brain decides which memories belong together could reshape schizophrenia research
Our memories of past events are typically not isolated, but they are linked to other related memories. This ability to establish connections between related memories is highly advantageous, as it helps us to recognize familiar ...
Science X / Salmon make clicking sounds when stressed—but no one knows how
It's noisy underwater, especially just below the surface. "A lot of the ambient noise is from the wind and waves," says Kristbjörg Edda Jónsdóttir, who is a research scientist at SINTEF, where she found out how much noise ...
Science X / Alarm bells fade: One pregnancy vaccine raised fears, but its earliest real-world test tells a different story
Questions about the safety of the RSVpreF vaccine, designed to protect infants from respiratory syncytial virus (RSV), for both mothers and babies during pregnancy have fueled considerable debate. One of the key concerns ...
Medical Xpress / HIV reveals more than 100 escape mutations against promising antibody therapies
Broadly neutralizing antibodies (bNAbs) are among the most promising new treatments for HIV, offering the potential to forego traditional daily doses of antiretroviral drugs. In one recent clinical study of bNAbs identified ...
Phys.org / Cut marks on 1.6 million-year-old bones reveal early humans moved prized meat
There is an old adage that goes, "you are what you eat," meaning that the food you consume helps build your body and fuel your mind. The same is true now as it ever was. When it comes to early humans, studying what they ate ...
Phys.org / How a single star can reshape an entire galaxy
Astronomers who simulate galaxies do not always get the same result, even when they start from identical conditions. New research from Leiden University shows that this is not a flaw, but a consequence of how galaxies behave—and ...
Phys.org / Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the ...
