While paleontologists have uncovered dozens of such Cambrian soft-bodied fossil sites—including China's early Cambrian Chengjiang biota in Yunnan and Canada's middle Cambrian Burgess Shale biota, the most famous examples of their kind—no equivalent top-tier soft-bodied fossil deposit had ever been found from the critical post-Sinsk Event time interval.

That changed over the past five years, however, with the discovery of the Huayuan biota—a world-class soft-bodied fossil deposit dating to shortly after the Sinsk Event. The deposit, located in Huayuan County, Hunan Province, was identified by a research team from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (CAS), whose findings were published in Nature on January 28.

The Australian monsoon season (ASM) typically arrives in mid-December to mid-January each year but arrived on 7 February 2025 during the 2024-2025 season, more than five weeks later than usual. A group of researchers investigated whether the official arrival of the ASM in 2024-2025 was due to a true delay of the monsoon season or monsoon measurement criteria and variations in local weather conditions.

While terahertz spectroscopy offers a promising solution for non-invasive chemical detection, conventional methods often struggle in real-world environments where sample geometry and packaging distort the signal. UCLA researchers addressed this by creating a robust chemical imaging system that integrates high-performance terahertz time-domain spectroscopy with deep learning neural networks. By analyzing individual time-domain pulses rather than terahertz spectra, this system effectively identifies explosives with pixel-level precision, achieving high classification accuracy even for targets concealed behind opaque coverings.

The metal-F bond formed on the fluorinated BiVO₄ photoanode in a near-neutral electrolyte promotes the adsorption and activation of CH₃OH, thereby significantly enhancing both the efficiency and selectivity of its photoelectrochemical oxidation to HCHO.The metal-F bond formed on the fluorinated BiVO₄ photoanode in a near-neutral electrolyte promotes the adsorption and activation of CH₃OH, thereby significantly enhancing both the efficiency and selectivity of its photoelectrochemical oxidation to HCHO.
