Positively and neutrally buoyant microplastics mainly outflow from the Seto Inland Sea into the Pacific Ocean, whereas negatively buoyant MPs hardly leave the Seto Inland Sea and are primarily deposited and degraded near river mouths. Traditional microplastics are difficult to degrade quickly and thus remain in the marine environment for long periods. However, the use of biodegradable microplastics can significantly reduce microplastic pollution in the marine environment, especially in sediments.

Forest fires cause irreversible ecological and economic losses worldwide, often exacerbated by delayed or inefficient rescue efforts. A new study presents a groundbreaking data-driven framework to revolutionize aviation emergency networks. By integrating fire probability predictions with multi-objective optimization, the research enables faster, cost-effective rescue planning tailored to real-world fire risks. Tested in China’s Hainan Province, the model reduces response times while balancing ecological and operational costs—offering a scalable solution for global forest protection.

This study presents a novel method to produce genetically modified rats by generating functional rat sperm in germ cell-deficient mice via blastocyst complementation with rat ES cells. Fluorescent rat ES cell lines were established, validated for pluripotency, and used to generate rat sperm in chimeric mice. The sperm successfully fertilized rat oocytes, producing viable offspring. This technique bypasses traditional chimera generation and reduces cost, offering an efficient platform for complex rat genetic engineering using ES cells.

Needles designed to be less than 1mm in length painlessly penetrate the outer layer of the skin and deliver medication into the body, according to new development by team of researchers.

Australian scientists have successfully developed a research system that uses ‘biological artificial intelligence’ to design and evolve molecules with new or improved functions directly in mammal cells. The researchers said this system provides a powerful new tool that will help scientists develop more specific and effective research tools or gene therapies.

Bladder cancer often becomes resistant to standard treatments due to its ability to evade apoptosis, the primary form of cell death targeted by conventional therapies. In a recent study, researchers from China developed a nanomedicine that triggers ferroptosis—a different cell death pathway—without needing external activation. Their proposed system not only killed resistant cancer cells but also enhanced the immune system's anti-tumor response, offering a promising dual-action therapy for bladder cancers.
