Worms with increased levels of the epigenetic mark H3K9me2 have a longer lifespan that can be passed down to future generations.

The wide range of cell types produced by single progenitors in the neocortex of mice may result from stochastic rather than deterministic processes.

A newly discovered mechanism that causes the 'Minute' phenotype in fruit flies can explain how organisms are able to eliminate the mutant cells that arise occasionally during development.

Two studies suggest that a determined adversary may be able to obtain genetic information that they should not have permission to access from some genealogy databases.

A new study in monkeys suggests that treating HIV infection early with antiretroviral therapy reduces the number of latent viruses, but has little impact on viral reactivation when treatment stops.
