Neuroscientists uncovered an energy-saving mode in vision-system neurons that works at the cost of being able to see fine-grained details.
The reasons why sleep is so vital often hide in unexpected parts of the body, as host Steven Strogatz discovers in conversations with researchers Dragana Rogulja and Alex Keene.
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.
Mistletoes have all but shut down the powerhouses of their cells. Scientists are still trying to understand the plants’ unorthodox survival strategy.
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.
