Study finds “Miracle Mineral Solution” kills bacteria only at levels that also harm human cells

Researchers at Wroclaw Medical University report that acidified sodium chlorite—sold online as “Miracle Mineral Solution” (MMS)—can destroy bacteria and biofilms, but only at concentrations that also damage human cells and may harm beneficial gut microbes. The team warns that homemade mixtures are particularly risky because dosing can vary widely, and it says there is no solid scientific evidence supporting MMS as a treatment for diseases such as cancer, autism or COVID-19.
Researchers at Columbia University have identified the precise mechanism by which rising carbon dioxide levels cool the upper atmosphere. The finding accounts for decades of observed stratospheric cooling amid surface warming. Their study appears in the journal Nature Geoscience.

中国研究人员表示，在寒冷干旱地区，葡萄糖基饲料补充剂可改善羊羔生长和肉质，该地区季节性饲料短缺限制了生产。（ECNS）西北生态环境资源研究院的中国科学院团队发现，向羊饮食中添加瘤胃保护葡萄糖（RPG）可提升生长并增加肌内脂肪，这是肉质的关键指标。
Researchers at the University at Buffalo have expanded the truncated Wigner approximation to simulate complex quantum systems on ordinary laptops, bypassing the need for supercomputers. This advancement, detailed in a September study in PRX Quantum, simplifies quantum dynamics for real-world applications. The method targets dissipative spin dynamics, making advanced physics accessible to more scientists.

A new study reveals that older men pass on significantly more disease-causing genetic mutations to their children due to the rapid proliferation of mutant sperm stem cells. Researchers found that the proportion of mutated sperm rises sharply with age, from 1 in 50 for men in their early thirties to nearly 1 in 20 by age 70. This phenomenon, driven by 'selfish' mutations, heightens risks for severe disorders in offspring.
