Supercomputer simulation shows why beneficial mutations rarely lead to hypermutators in real organisms

In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from the University of Michigan has used simulations on the Pittsburgh Supercomputing Center's Neocortex ...

Slow, silent 'scream' of epithelial cells detected for first time

It has long been thought that only nerve and heart cells use electric impulses to communicate, while epithelial cells—which compose the linings of our skin, organs and body cavities—are mute, serving mostly as protective ...
