The ingredients for reactions ancestral to metabolism could have formed very easily in the primordial soup, new work suggests.
Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
Plants ignore the most energy-rich part of sunlight because stability matters more than efficiency, according to a new model of photosynthesis.
Going without sleep for too long kills animals but scientists haven’t known why. Newly published work suggests that the answer lies in an unexpected part of the body.
New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
Cells in symbiotic partnership, sometimes nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways.
Mitochondria are most famous as sources of metabolic energy. But by splitting and combining, they can also release chemical signals to regulate cell activities, including the generation of neurons.
A computational study reveals surprising flexibility hidden within metabolic networks, providing new evidence for an evolutionary concept called exaptation.
