Viruses in the Gut Have a Genetic Way to Fight Bacteria, Potentially Helping to Deal with Superbugs
2+ hour, 3+ min ago (622+ words) JAKARTA - A number of viruses that live in the human gut are able to produce genetic variations quickly to evade bacterial defenses. This finding has the potential to help develop alternative therapies when antibiotics are no longer effective. Euronews quoted…...
Saber-Toothed Cats Were A Diseased, Inbred Mess Before They Went Extinct, New Research Suggests
4+ hour, 2+ min ago (316+ words) Whether waking up to a slobber-soaked ribbon draped across one's face or an unfortunately massacred mouse 'gifted' in one's slippers, anyone intimate with a cat can attest that their tiny tiger is evolutionarily built to hunt....
DeepSeek V4 Pro 0813 发布：新一代混合推理大模型带来哪些升级与行业影响
7+ hour, 55+ min ago (805+ words) 一个多月前，行业还在争论「R1 式深度思考链」是否是推理问题的万能解；这一次，DeepSeek 给出的答案是第三种路径——把「快」和「深」同时装进一个模型，而不是让用户二选一。 2026 年 8 月 13 日，深度求索（DeepSeek）正式发布新一代旗舰模型 DeepSeek V4 Pro 0813，同步开放 API 与开源权重下载。这是继 V3、R1、V4 基础版之后，DeepSeek 在通用对话、代码生成与深度推理三条线上首次「三合一」的旗舰版本，官方定位为面向企业与开发者的规模化生产级模型。 读完本文，你可以得到三个判断： V4 Pro 0813 相比前代到底改了什么、对你的项目是否值得升级、以及如何用 10 分钟做一次低成本的迁移前验证。 需要先说明的是…...
Older adults with a strong sense of purpose showed measurably slower epigenetic ageing on several DNA-based biological clocks — an association equivalent to roughly two years of biological age between people with high and low purpose, though researchers cannot yet say purpose itself caused the difference.
9+ hour, 59+ min ago (1130+ words) In 1,572 older U.S. adults, purpose tracked four health-oriented methylation clocks but not nine chronological-age clocks. The cross-sectional result cannot establish cause. By The Long View · Edited by Lachlan Brown Published August 16, 2026 · How we edit A stronger sense of purpose was associated…...
Gut viruses are evolving new tricks to beat bacteria — and could help fight superbugs
1+ day, 5+ hour ago (668+ words) Viruses that selectively target and kill bacteria — also known as bacteriophages or simply phages — infect bacteria but leave human cells alone. Once they attach to a bacterial cell, they inject their genetic material, hijack the cell's machinery and force it…...
