Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers the generation of ATP, the cell's fuel. Scientists have solved the mystery of how complex I works: Conformational changes in the protein combined with electrostatic waves move protons into the mitochondrial matrix.

Your cells look young for their age, compared to a chimp's

Many humans live to see their 80s, some even reach 100. But chimpanzees rarely make it past 50, despite sharing 99% of our genetic code. While modern medicine has added years to human lifespans, a study points to a more ancient explanation why humans are the long-lived primate. Part of the secret to human longevity may lie in chemical changes to our DNA that slowed the rate of aging after human ancestors diverged from chimps.

Real neurons are noisy: Can neural implants figure that out?

Signals sent from the retina to the brain have a lot of background noise, yet we see the world clearly. Researchers show that to achieve visual clarity the brain must accurately measure how this noise is distributed across neurons when processing the signals sent down the optic nerve. These results are likely to shape the design of future retinal prosthetics and other brain-machine interfaces.

Human white blood cells use molecular paddles to swim

Human white blood cells, known as leukocytes, swim using a newly described mechanism called molecular paddling, researchers report. This microswimming mechanism could explain how both immune cells and cancer cells migrate in various fluid-filled niches in the body, for good or for harm.

People react better to both negative and positive events with more sleep

New research finds that after a night of shorter sleep, people react more emotionally to stressful events the next day -- and they don't find as much joy in the good things. This has important health implications: previous research shows that being unable to maintain positive emotions in the face of stress puts people at risk of inflammation and even an earlier death.

Risk gene for Alzheimer's has early effects on the brain

A genetic predisposition to late-onset Alzheimer's disease affects how the brains of young adults cope with certain memory tasks. Researchers find are based on studies with magnetic resonance imaging in individuals at the age of about 20 years. The scientists suspect that the observed effects could be related to very early disease processes.

Doctors get plenty of advice on starting treatment; this could help them know when to stop

Decades of effort have improved the chances that patients will get the scans, routine tests and medicines that can do them the most good - and avoid the ones that won't help them at all. But in the push toward evidence-based medicine, a new study says, a key step has mostly gotten overlooked: helping doctors stop or scale back - or deintensify - treatment once it has started.

Excessive lung release of neutrophil DNA traps may explain severe complications in COVID-19 patients

Researchers have detected significant amounts of DNA traps in distinct compartments of the lungs of patients who died from Covid-19. These traps, called NETs, are released massively into the airways, the lung tissue and the blood vessels. Such excessive release could be a major contributor to severe disease complications leading to in-hospital death.
