Cells become zombies when the ends of their chromosomes are damaged – a tactic both helpful and harmful for health

The protective caps at the ends of chromosomes naturally shorten over time. Researchers found that direct damage can prematurely trigger senescence and contribute to age-related diseases like cancer.

Artificial intelligence can discriminate on the basis of race and gender, and also age

Algorithms have been shown to discriminate on the basis of race and gender. Studying age-related discrimination is essential to develop more equitable AI systems and technologies.
