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.

Not everyone is male or female – the growing controversy over sex designation

Millions of people do not fit neatly into male or female sex designations at birth, and wrong identification can set them up for a lifetime of physical and mental harm.

Scientists are on a path to sequencing 1 million human genomes and use big data to unlock genetic secrets

The first full human genome was sequenced 20 years ago. Now, a project is underway to sequence 1 million genomes to better understand the complex relationship between genetics, diversity and disease.

The sex gene SRY and Parkinson’s disease: how genes act differently in male and female brains

Parkinson’s disease is twice as common in men than in women. A sex gene called SRY, found only in men, could go some way to explaining this – and might pave the way for potential treatments.

Ten ethical flaws in the Caster Semenya decision on intersex in sport

Athlete Caster Semenya will need to take hormone-lowering agents, or have surgery, if she wishes to continue her career in her chosen events. But the decision to ban her is flawed on many grounds.

‘Gene drives’ could wipe out whole populations of pests in one fell swoop

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.
