Exercise plus omega-3 curbs tooth root inflammation in rat study
Heather Vogel AI द्वारा उत्पन्न छवि तथ्य-जाँच किया गया
A peer‑reviewed study in rats reports that moderate exercise combined with omega‑3 supplementation improved immune markers and limited bone loss in chronic apical periodontitis, an inflammatory infection at the tooth’s root tip often arising from untreated decay. The authors and research backers stress that human trials are needed to confirm clinical relevance.
University at Buffalo enables quantum simulations on laptops
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.
Study shows older fathers transmit more disease mutations through selfish sperm
AI द्वारा रिपोर्ट किया गया
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.
Study reveals hidden scale of global plastic waste

A new scientific approach has quantified the full extent of plastic waste entering the environment, uncovering far more pollution than previously estimated. The research, published in a leading journal, highlights mismanaged plastics in rivers, soils, and oceans, urging immediate policy responses.
Bile acids hinder liver cancer immunotherapy, supplement may help
Scientists at the Salk Institute have found that certain bile acids in the liver suppress immune cells, reducing the effectiveness of immunotherapy for liver cancer. Supplementing with ursodeoxycholic acid (UDCA) reversed this effect in mice, shrinking tumors. UDCA, already approved for other liver conditions, could soon enter clinical trials for cancer treatment.
