Synthetic biology experiments suggest a “MultiFate” model for how genetically identical cells become the many different types found in complex organisms like us.
Was the addition of mitochondria a first step in the formation of complex cells or one of the last? A new study of bacteria tries to answer this contentious question in evolutionary biology.
The electrical chatter of our working memories reflects our uncertainty about their contents.
Researchers have discovered that environments favoring clumpy growth are all that’s needed to quickly transform single-celled yeast into complex multicellular organisms.
Studies of sleep are usually neurological. But some of nature’s simplest animals suggest that sleep evolved for metabolic reasons, long before brains even existed.
New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.
Paradoxically, the abundance of tight interactions among living species usually leads to disasters in ecological models. New analyses hint at how nature seemingly defies the math.
