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 / Why some reefs recover faster than others—mathematical model spotlights coral recruitment patterns
Climate-driven disturbances such as marine heat waves are rapidly reducing coral cover and degrading reef ecosystems worldwide. Using a mathematical model, a research team led by Subhendu Chakraborty at the Leibniz Center ...
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 / AI approach uncovers dozens of hidden planets in NASA's TESS data
Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA's Transiting Exoplanet Survey Satellite ...
Phys.org / A spinel crystal structure exhibits unusual, pressure-induced superconductivity
Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like ...
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 ...
Phys.org / Trapped subsurface heat may have triggered Antarctica's sudden sea ice loss
In 2016, Antarctic sea ice, which had previously shown record expansion, shifted rapidly toward unusually low levels. This abrupt shift left scientists scratching their heads, wondering why it had vanished so quickly despite ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
