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.
The long, variable times that some diseases incubate after infection defies simple explanation. An idealized model of tumor growth offers a statistical solution.
Kidneys sniff out signals from gut bacteria for cues to lower blood pressure after meals. Our understanding of how the symbiotic microbes affect health is becoming much more molecular.
To better understand the molecules described by the latest prize in medicine, we will need the technique recognized by the latest prize in chemistry.
Sex might help natural selection purge excessive mistakes from our genes.
