Scientists from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences 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 of the annelids, a group of animals that includes bristle worms, earthworms, leeches, and peanut worms.

A gapless, telomere-to-telomere reference genome of Capsella bursa-pastoris reveals extensive subgenome divergence and large structural variations, providing a pivotal resource for polyploid plant evolution and functional genomic research.

Protecting old-growth forests significantly boosts soil physical–biochemical quality, dissolved organic matter chemodiversity, and beneficial mycorrhizal fungi, offering a proven pathway to safeguard endangered Ocotea porosa and mitigate climate change.

A new field evaluation identifies eight novel papaya hybrid lines with superior agronomic traits, early fruiting, and enhanced tolerance to Moroccan watermelon mosaic virus (MWMV), offering a sustainable solution to boost smallholder productivity in Kenya.

Current homogeneity testing has long relied on a planar “slice‑then‑measure” approach. Professor Sen Han’s team proposes a radial absolute measurement method for cylindrical surfaces. This method requires no slicing, is low‑cost, and enables direct non‑destructive measurement of refractive index distribution, offering an efficient pre‑screening tool for semiconductors, LiDAR, medical imaging, and more.

A new commentary outlines China’s ambitious national park strategy, which balances strict ecological protection, public welfare, and sustainable development to conserve key ecosystems and prioritize global biodiversity goals.

New research on Australia’s K’gari reveals high‑intensity human‑caused wildfires drastically reduce vertebrate diversity in fire‑adapted Banksia aemula woodlands, underscoring urgent needs for evidence‑based fire management.

Lensless multi-core fiber endoscopes suffer from honeycomb-like artifacts that obscure fine structures. To overcome this, researchers from Tsinghua University and Technische Universität Dresden developed SGARNet, which allows us to cleanly erase long-standing honeycomb artifacts via the frequency domain, bypass the need for massive paired data, and seamlessly recover high-fidelity images. The technique will open new avenues for future minimally invasive diagnostics and advanced endoscopic technologies.
