Researchers develop model to study heavy-quark recombination in quark-gluon plasma
Researchers from the HEFTY Topical Collaboration investigated the recombination of charm and bottom quarks into Bc mesons in the quark-gluon plasma (QGP). They have developed a transport model that simulates the kinetics of heavy-quark bound states t.....»»
Dutch winter bee mortality rate above 20%, finds annual survey
In the winter of 2023–2024, 21.2% of the Dutch population of honeybee colonies died. While this mortality rate is lower than that of the previous winter, it still represents a worryingly high number of bee colonies that did not survive this winter.....»»
Republicans angry that ISPs receiving US grants must offer low-cost plans

Researchers listen to the hearts of bats in flight
Researchers from Konstanz have measured the heart rate of bats over several days in the wild, including complete flights—the first time this has been done for a bat species. To record the heart rate of male common noctule bats during flight, the sc.....»»
Tensor-force effects on nuclear matter in relativistic ab initio theory
Tensor force is a crucial ingredient of the nucleon-nucleon (NN) interaction, and has an important impact on the structural and dynamical properties of the nuclear many-body system. Many efforts have been devoted to studying the influence of the tens.....»»
New plasma jet technology effectively treats fungal nail infections
Recently, the team led by Prof. Huang Qing from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences proposed using a portable pulsed cold air plasma jet (PP-CAPJ) to treat Trichophyton rubrum in nails. They revealed that the s.....»»
Super-resolution machining of single crystalline sapphire by femtosecond laser-induced, plasma-assisted ablation
A new study in Opto-Electronic Advances discusses super-resolution machining of single crystalline sapphire by GHz burst mode femtosecond laser-induced plasma assisted ablation......»»
Polar warming may be underestimated by climate models, ~50 million year old climate variability suggests
Polar regions are known to be warming at an enhanced rate compared to lower latitudes, with the Intergovernmental Panel on Climate Change citing a ~5 °C increase in air temperature over Arctic land masses during the 20th century and the highest rate.....»»
EU moves ahead with provisional tariffs on Chinese EV imports
The EU confirmed that provisional duties will be imposed on Chinese automakers including SAIC, which faces a 37.6 percent tariff on top of the existing 10 percent rate, while Geely and BYD will be hit with additional charges of 19.9 percent and 17.4.....»»
EU moves ahead with provisional tariffs on EV imports from China

Searching for dark matter with the coldest quantum detectors in the world
One of the greatest mysteries of science could be one step closer to being solved. Approximately 80% of the matter in the universe is dark, meaning that it cannot be seen. In fact, dark matter is passing through us constantly—possibly at a rate of.....»»
Right to repair compliance checks rate iPhone 15 an A, Vision Pro an F
Right to repair compliance checks carried out in New York have revealed that many products covered by the law do not appear to be in compliance. Three Apple products were checked, gaining scores ranging from A right the way through to F, suggestin.....»»
TikTok algorithm could have US-only version; company demurs
The TikTok algorithm could be split, claims a report, with a US-only version used for the hugely popular app to try to avoid a ban. Developer Bytedance has tweeted that the report is not accurate, but its message appears to be more a repetition of.....»»
X-ray binary Swift J1727.8-1613 has a large relativistic jet, observations show
Using the Very Long Baseline Array (VLBA) and the Long Baseline Array (LBA), astronomers have observed a black hole low-mass X-ray binary known as Swift J1727.8-1613. As a result, they found that the system hosts a highly extended and bright relativi.....»»
