What are the hormones that cause cravings during pregnancy?
Multiple hormones produced by the mother, placenta and the foetus drive and coordinate the amazing biological changes and development of the baby that occur with conception, foetal growth and birth.
The link between season of birth and the risk of having allergies is well known. A new study sheds light on why this link exists.
Identical twins share the same DNA.
Just because identical twins have exactly the same DNA, doesn't mean they will have the same physical features.

Many take for granted that epigenetics will lead to a more inclusive and equal society. But there are signs that quite the opposite could be true.
Genes play a key role in our state of mind.

Gene mutation associated with schizophrenia could have implications for other developmental disorders.
We all know that stress can wreak havoc on your health but what does it do to your genes?
A mouse embryo, like this one, looks a lot like that of a fish, a frog or a human at a certain point in its development.
Scientists have discovered the genetic "switch" that causes many animals, including fish, frogs and humans, to look the same at a certain point in embryonic development.
Research on how our lifestyles affect our genes raises the possibility of giving your future kids a better start in life before they're even born.
Grandad, why did you eat all those pizzas?
A new study from Denmark shows that a man's weight can affect the information carried by his sperm.
Don’t forget the genes!

It's time for neurons to share the glory. Gene activity isn't just a background utility of the brain, but an integral part of its operation.

A new study has looked at the 'father effect' in epigenetics.
Who’s a clever boy?
The study of human intelligence dates back well over 100 years. And the core disagreement between researchers and theorists is whether differences are genetic or largely influenced by the environment.
Family resemblance isn’t only down to genes, but also to the influence of the environment on those genes.
Epigenetics is increasingly used as a buzzword to sell pseudoscientific products, but the truth of epigenetics is even more interesting – and complex – than the quacks claim.

It takes a careful balance between art and science to illustrate the processes that take place within our cells and explain the complexities of epigenetics.
Epigenetic molecules play a different melody on different people’s genomes, and this might be contributing to some developing autism.
The epigenetic 'musicians' that play our genomes in different ways might help us understand the causes of autism.
Will Russian science return to the bad old days of Stalin?
Some Russians are looking back admiringly to a tyrannical scientist from Stalinist times – and using the new field of epigenetics to bolster their case.
Genetic therapy might be able to reverse the harmful effects of sickle cell anaemia.
Gene therapy is allowing us to switch on natural beneficial mutations to counteract the effects of negative mutations in diseases such as sickle cell anaemia.
Could genetics be a legal get-out clause?
A recent study showing that the potential for committing a sex crime may be written in our genes is interesting but unlikely to help prevent sex offenses.
The Human Genome Project was just the beginning. The Epigenome Roadmap is now telling us how all these genes switch on and off in different parts of the body, and how they go wrong with disease.
There's still a lot we don't know about how various genes are switched on and off. But a new project is seeking to shed light on the complex world of epigenetics.
A mother’s healthy and varied diet during pregnancy might give her child a head start to healthy eating.
Our parents teach us what is to eat. But this process begins well before the fight to get toddlers to eat their veggies. Not only do our parents give us the genes that define our taste receptors, research…
