Stochasticity is everywhere – and finding the order in disorder can unlock new ways to understand biology. Erlon Silva - TRI Digital/Moment via Getty Images

Cancer evolution is mathematical – how random processes and epigenetics can explain why tumor cells shape-shift, metastasize and resist treatments

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.

What we learn from a fish that can change sex in just 10 days

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.

Ageing cells reveal features of cancer

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…

Meet the epigenome: the next genomic frontier

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…
