Scientists in Zurich have shown that stem cell transplants can reverse stroke damage by regenerating neurons, restoring motor functions, and even repairing blood vessels. The breakthrough not only healed mice with stroke-related impairments but also sugge
阅读全文Heating alone won’t drive soil microbes to release more carbon dioxide — they need added carbon and nutrients to thrive. This finding challenges assumptions about how climate warming influences soil emissions.
阅读全文A new AI model from NYU Abu Dhabi predicts solar wind days in advance with far greater accuracy than existing methods. By analyzing ultraviolet solar images, it could help protect satellites, navigation systems, and power grids from disruptive space weath
阅读全文A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter halo. An international team of astronomers, including Rutgers scientists, used powerful radio telescopes and computer modeling to co
阅读全文The Dead Sea isn’t just the saltiest body of water on Earth—it’s a living laboratory for the formation of giant underground salt deposits. Researchers are unraveling how evaporation, temperature shifts, and unusual mixing patterns lead to phenomena like “
阅读全文Scientists from the University of St Andrews have discovered that ions in solar flares can reach scorching temperatures more than 60 million degrees—6.5 times hotter than previously believed. This breakthrough challenges decades of assumptions in solar ph
阅读全文Late-stage planetary collisions reshaped Earth and its neighboring planets, delivering water, altering their atmospheres, and influencing their tectonics. New findings suggest these violent impacts were central to both planetary diversity and the origins
阅读全文Scientists at Harvard have discovered how salts like lithium bromide break down tough proteins such as keratin—not by attacking the proteins directly, but by altering the surrounding water structure. This breakthrough opens the door to a cleaner, more sus
阅读全文被称为ecDNA(染色体外环状DNA)的流氓DNA环可能是破解胶质母细胞瘤致命抗性的关键。这些环状DNA在肿瘤形成之前就出现,可为科学家提供关键预警系统,在疾病变得不可治愈前创造干预机会。
阅读全文日内瓦大学的科学家们创建了首个亚种水平肠道细菌详细目录,为结直肠癌检测开辟了强大新途径。通过对粪便样本应用机器学习技术,他们实现了90%的检出率——几乎与结肠镜检查相当,但成本与不适感大幅降低。这一突破性进展有望彻底改变癌症早期筛查模式,帮助人们在病情恶化前发现疾病。
阅读全文天文学家探测到一颗白矮星正在吞噬富含水的冰冻行星碎片,其化学成分特征提供了迄今最清晰的证据:在太阳系外存在着能输送生命的冰质天体。这一发现表明,彗星和矮行星等碎片可能是行星系统的常见组成部分。
阅读全文来自宇宙黑暗时期的微弱氢信号或很快就能帮助确定暗物质粒子的质量。模拟实验表明,未来基于月球的观测站将能区分温暗物质和冷暗物质,为这个长久以来悬而未决的宇宙隐形支柱问题提供答案。
