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.
The identification of SNIPPs, a set of proteins found primarily at the brain’s synapses, brings science closer to understanding why we need to sleep.
The more closely geneticists look at complex traits and diseases, the harder it gets to find active genes that don’t play some part in them.
An ambitious study in yeast shows that the health of cells depends on the highly intertwined effects of many genes, few of which can be deleted together without consequence.
