Study Reveals ATM-Driven Mechanism Behind Telomere-Induced Senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

Mitochondrial Mutation Found to Rewire Immune Function

Scientists have discovered how a mitochondrial mutation rewires immune function in a model of inherited primary mitochondrial disorders, which often lead to severe disability and death.

Ultrasound-Controlled Mechanochemical Systems Offer Precision Drug Activation

Conventional drug delivery often relies on passive diffusion or chemical triggers, which may lead to systemic exposure, toxicity, and decreased therapeutic performance.

Sabotaging T Cell Exhaustion for Cancer Therapy

Like all hardworking things, the cytotoxic T lymphocytes (CTLs) of the immune system charged with detecting and destroying cancer cells tend to get very tired-so much so, in fact, that they can even die from exhaustion.

Researchers Discover Molecular Switch That Helps Breast Cancer Cells Survive Stress

Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves.

Global Constraint Principle Offers Fresh Insight into Life’s Growth Limits

A research team including a scientist of Earth-Life Science Institute (ELSI) at Institute of Science Tokyo, Japan, has identified a novel principle in biology that mathematically explains why the growth of organisms slows as nutrients become more abundant-a phenomenon known as "the law of diminishing returns."
