Stem cells could help regenerate diseased or damaged parts of the body – but first, scientists need to make the cells forget their own histories.
Stochasticity is everywhere – and finding the order in disorder can unlock new ways to understand biology.

An epigenetic model of cancer that incorporates the concept of stochasticity could also explain why cancer risk increases with age and how biological development can be reversible.

Our study in mice shows epigenetic changes in the mother can be passed to her offspring to influence a critical time in how the spine develops.
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.
‘Amphy’ has features of both simple and more complex forms of life – and so can help us understand important steps in evolution.

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.
Cancer disproportionately affects the old.

The older we get, the higher our risk of cancer. With age, we accumulate exposure to environments and chemicals that increase the risk of acquiring cancer-causing mutations. But the danger doesn’t increase…
The epigenome is changed by what we eat and drink, smoking, stress, pollution, sun exposure and other environmental factors.

Thanks to the Human Genome Project we now have a complete genomic map. But, simply having a map doesn’t give you all the information. For a map to be useful, you still need know where to go, the best way…
