1. 科学家给线虫喂食磁性细菌，结果它们的寿命延长了43%。

• ✍️ 作者：未知作者
• 🏷️ 关键词：bacteria、regex:bacter(ia|ial|ium)
• 📝 描述：A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of cell death linked to iron buildup and oxidative stress.

2. 科学家发现一条“不可能”的细胞存活途径，或有助于对抗癌症。

• ✍️ 作者：未知作者
• 🏷️ 关键词：cancer、pathway
• 📝 描述：Scientists discovered a surprising backup system that lets mammalian cells make the essential amino acid cysteine even when the pathways once considered indispensable are disabled. The same survival mechanism may help cancer cells resist treatment, raising the possibility that shutting it down could make tumors easier to kill.

5. 科学家们以为他们已经了解这种已有70年历史的白血病药物的作用机制。

• ✍️ 作者：未知作者
• 🏷️ 关键词：leukemia
• 📝 描述：A 70-year-old leukemia drug is still revealing new secrets. Researchers found that removing a protein called NUDT5 protected cells from the drug, even though simply blocking the protein had little effect. The unexpected result points to a hidden cellular role that could help explain why people respond differently to certain leukemia treatments.

6. 衰老肌肉力量下降的原因可能是科学家们忽略的。

• ✍️ 作者：未知作者
• 🏷️ 关键词：aging
• 📝 描述：A newly identified breakdown in communication between nerves and muscles could help explain why people lose strength as they age. Researchers were able to improve muscle strength in an animal model by targeting a key protein, raising hopes that some age-related weakness could eventually be treated.
