Right combination of diet and bacteria limits cancer progression

The diet of a person can have significant effects on the gut microbiome, i.e. the populations of microorganisms such as bacteria which live in the human gut. It is well recognised that dietary habits through complex metabolic interactions contribute to cancer prevention. More specifically, diets rich in fibre reduce the risk of developing specific cancers…

Evolving alongside viruses impacts susceptibility to future infections

Researchers have shown that when fruit flies co-evolve with viruses, different genetic changes occur to those caused by encountering a virus for the first time, altering the insects’ susceptibility to future infection. The findings, published in eLife, help to address a fundamental question in infectious disease biology: why are some individuals genetically resistant to infection,…
