Phys.org / How poison frogs built a chemical weapons system one evolutionary step at a time
Poison frogs are small and brightly colored amphibians that originate from Central and South America. As suggested by their name, these frogs can release highly toxic chemicals from their skin, which deter and neutralize ...
Phys.org / Why ultrashort laser pulses could make low-power electron sources far more practical
A new theoretical study finds shorter laser pulses achieve higher quantum efficiency for photoemission from a solid surface without increasing power or intensity. Using light to knock electrons loose from a surface—known ...
Medical Xpress / How a tiny circle of repeat offenders poisoned 100s of gold-standard medical trials for over a decade
Randomized Controlled Trials (RCTs) are the gold standard of medical research as random assignment approach helps eliminate bias and yields the most reliable evidence on whether a treatment truly works. Since RCTs sit at ...
Phys.org / Research at Chernobyl and Fukushima shows how radioactive materials move in the environment
When nuclear accidents happen, many people imagine radiation spreading everywhere and lasting forever. The reality is more complex. Radioactive materials move, change and sometimes disappear faster than people expect.
Phys.org / Mind the gap! The semiconductor industry is relying on the wrong materials
2D materials are widely seen as a promising path toward better computer chips. Researchers at TU Wien have now shown that some of these materials are unsuitable due to an underestimated effect. But there are alternatives.
Phys.org / As the world faces yet another crisis, why are leaders still resisting remote work?
At 9 p.m., shops, restaurants and cafes go dark across the city of Cairo, where a stringent curfew has been imposed to mitigate the energy shock triggered by the conflict in the Gulf. The measure may prove difficult to enforce ...
Phys.org / Cambrian microfossils reveal earliest known ringed worms from 535 million years ago
Scientists have uncovered the earliest fossil evidence of annelids (ringed worms) in Cambrian microfossils dating back approximately 535 million years ago. This discovery offers fresh insights into the origin and early evolution ...
Phys.org / Which 'money type' are you? New research maps financial habits of young Australians
Under 35, navigating the cost-of-living and trying to get ahead? New research from Southern Cross University, QUT and Griffith University challenges the idea that financial literacy alone addresses this problem. Instead, ...
Phys.org / Mapping the hidden structure of the universe
The universe has a hidden structure, and a University of Virginia professor is mapping it in 3D, using 46 million galaxies and quasars and 19 million stars. Satya Gontcho A Gontcho, an assistant professor in the Department ...
Phys.org / Rare soft-bodied fossil from Quebec reveals a new jellyfish relative from 450 million years ago
Canadian researchers studying 450-million-year-old fossils near Quebec City have identified a new species of basal-medusozoan: Paleocanna tentaculum, a soft-bodied, tube-shaped polyp with a ring of tentacles. Closely related ...
Medical Xpress / Serotonin spikes may worsen tinnitus by directly activating the brain's auditory circuit
The same neurotransmitter commonly leveraged to relieve symptoms of depression and anxiety also may exacerbate a vexing condition known as tinnitus, according to new research published in the Proceedings of the National Academy ...
Phys.org / The physics of brain development: How cells pull together to form the neural tube
In about one out of every 1,000 pregnancies, the neural tube, a key nervous system structure, fails to close properly. Georgia Tech physicists are now helping explain why this happens, having uncovered the physics that drive ...
