This decades-long study found that living in poorer communities changes how genes are regulated.
Epigenetic clocks are a fascinating new technology, but some potential applications are controversial.
Pediatric epigenetic clocks have the potential to accurately assess biological age. However, possible applications in law enforcement and immigration raise ethical issues.
The male bluehead wrasse defends his group of yellow females, one of whom has to step-up and take charge if he leaves.
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.

Research suggests that scientists' understanding of biological age may not be as robust as we thought.
Biological factors shape sexual preference.
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.
Adults born via IVF are as healthy as their naturally conceived peers.
New research suggests that while babies conceived via IVF experience changes to their genes, these differences disappear by adulthood.
Reversing lactose intolerance might make it possible for adults to enjoy a milkshake again.

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.
Genes aren't destiny, but you don't need epigenetics to make the case.
Erectile dysfunction can take the light out of men’s lives.
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.
Our genes are important when it comes to aptitude for sleeping soundly.
Naloxone is often used to revive people overdosing from opioids.
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.
Babs turned to technology to clone her dog Sammie.
Humans, and indeed pet dogs, are more than just products of genes – even before the moment of conception, environments play a vital role in shaping us.
Rey (Daisy Ridley), in
Star Wars: The Last Jedi, ponders the light and dark sides of the Force.
Star Wars: The Last Jedi leaves many questions about the saga in a galaxy far, far away unanswered. Fortunately, biology may offer a insights on the Force, midi-chlorians, clones, and Rey's lineage.
Researchers are using epigenetics to find ways to 'turn off' bacteria's ability to cause infections.

The rapid growth of genetic testing and data-gathering could revolutionize health and medicine if governments work to protect people against privacy and societal risks.
The offspring of mice who don't get enough DHA during pregnancy are more likely to have pups that display schizophrenia-like symptoms.
A new study in mice raises hopes that we could live longer and be healthier.
Darwin was right again.
Epigenetics is consistent with the theory of evolution – in fact, Darwin predicted that tiny parcels might somehow provide a flow of information from experience to inheritance.
