How cells correct errors under time pressure

How does a cell balance risk and speed when dividing? EPFL scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently.

So-called junk DNA plays critical role in mammalian development

Nearly half of our DNA has been written off as junk, the discards of evolution: Sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or ...

Gut microbes' role in mammals' evolution starts to become clearer

An international collaboration led by Oregon State University scientists has made a key advance toward understanding which of the trillions of gut microbes may play important roles in how humans and other mammals evolve.

Pioneering discovery of an odor-detecting receptor enhancer

Each odor-detecting neuron (referred to as olfactory sensory neuron from here on), chooses a single odorant receptor gene from a fairly large number of options that are split into class I (fish-like) and class II (terrestrial-specific) ...

Grasses, mammals, and their co-evolution

After millions of years of amphibians, dinosaurs, and early mammals ruling the forests and swamps of the hot, humid Mesozoic and early Cenozoic, a new habitat emerged. Small patches of grasslands sprang up and spread as the ...
