Phys.org / Bioelectronic platform enables precise H₂S delivery to cells, turning a toxic gas into a therapeutic tool
A toxic gas known for its "rotten egg smell" has been transformed into a therapeutic tool. A research team at KAIST has developed a technology to precisely control hydrogen sulfide (H2S) using electrical signals, bringing ...
Phys.org / Combining algae and oyster shells for biodiesel born in the bayou
Biodiesel is a renewable fuel and offers a sustainable and potentially carbon-neutral alternative to petroleum products. Yet production costs remain a hurdle to its widespread use. Now, researchers have developed an inexpensive ...
Phys.org / Stabilized hybrid photocatalyst boosts artificial photosynthesis efficiency
A hybrid photocatalyst system from Science Tokyo tackles an overlooked flaw in artificial photosynthesis to dramatically improve CO2-to-formate conversion. Unlike conventional designs where light degrades the molecular catalyst, ...
Phys.org / Scalable flow chemistry speeds deuteration of fatty acids with tunable isotope selectivity
The National Deuteration Facility has developed a capability to use a flow chemistry process to increase efficiency, increase production capacity and reduce decomposition in the synthesis of deuterated molecules.
Phys.org / Britain's hibernating hazel dormice are getting lighter in spring as temperatures rise, study suggests
Britain's hazel dormice are getting lighter in spring but fatter in autumn as our climate changes, suggests new research in Scientific Reports. The study, titled "The effects of climate and land cover on hazel dormouse (Muscardinus ...
Phys.org / Polymer uses movable molecular rings to overcome durability–degradability trade-off
Modern polymer materials face a fundamental challenge: they must remain strong and durable during use, yet ideally degrade when they are no longer needed. Designing materials that satisfy both requirements has long been a ...
Phys.org / Genomes reveal five E. coli 'armor' types behind most multidrug-resistant bloodstream infections
The first large-scale genetic study of E. coli's protective armor has identified the five capsule types that are responsible for 70% of all multidrug-resistant bloodstream infections in Europe. Researchers, including those ...
Phys.org / Earth's 40,000-year tilt cycle links Antarctic ice growth to subtropical productivity
Cycles in the growth and decay of Antarctica's ice sheets once shaped marine biological productivity thousands of miles away in the subtropical ocean, according to new research led by scientists at the University of Wisconsin-Madison. ...
Phys.org / Chandra resolves why black holes hit the brakes on growth
Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA's Chandra X-ray Observatory and other X-ray telescopes ...
Phys.org / Continued monitoring of sunken Soviet submarine shows ongoing radioactive leakage, but little impact
In 1989, the Soviet nuclear-powered attack submarine Komsomolets sank to the bottom of the Norwegian Sea, along with its nuclear reactor and two nuclear warheads onboard. Komsomolets was constructed with a titanium alloy ...
Phys.org / Europe's Late Neanderthals descended from a single population, DNA analysis suggests
A study incorporating new DNA data and archaeological evidence has shown that the last Neanderthals in Europe experienced a major population turnover, resulting in little diversity in their gene pool prior to their disappearance ...
Phys.org / How archaeology is preserving evidence of the Yahidne war crime
Archaeology is not just a powerful tool for revealing insights into the ancient past, but it can also be applied to more recent events. In a new paper published in the journal Antiquity, scientists reveal how archaeological ...
