Scientists are revealing the extent to which our behaviour is influenced by our genes, calling into question our capacity for free will. But there is still scope for change.
Jumbo squids live in extreme environments. Tiny genetic modifications allow them to move back and forth from the surface of the ocean to its bottom, killing and eating everything in their path.
New research provides a template for understanding the role of genetic switches in the development of complex diseases whose causes have so far evaded scrutiny.
The pandemic response has put the long-term health and well-being of children and adolescents at risk, with the possibility of seismic shifts in population health if we do not act.
Pediatric epigenetic clocks have the potential to accurately assess biological age. However, possible applications in law enforcement and immigration raise ethical issues.
When a male bluehead wrasse is removed from the group he dominates, the largest female changes sex, rapidly transforming ovaries into sperm-producing testes. Molecular research shows how.

A new study of nearly 500,000 individuals finds that many genes affect same-sex behavior, including newly identified candidates that may regulate smell and sex hormones.
You may think that your milk-drinking, ice cream-licking days are behind you as you battle the discomfort of lactose intolerance. But there maybe be a way to reverse the situation.
Discovering a genetic basis for erectile dysfunction that is linked to Type-2 diabetes will make it easier to identify those at risk – and novel treatments.
Separating children from their parents is not just a psychological stress, it’s a DNA stress. Scientific research shows that early life stress may have irreversible effects on how DNA works in the cells of the body.
The traumatic separations of children and parents initiated at the border can cause permanent changes in the structure of the infants’ and children’s brains and the activity of their genes.
Scientists are just starting to understand how your parents’ genes and experiences might shape your own susceptibility to dangerous drugs. Could that help to stop addictions before they start?
Cancer is a disease of our genes, but resistance to therapy might go beyond cancer mutations. The DNA stays the same, but cancer cells outsmart the drugs by switching their gene activity.
