Rejuvenation science: Rewinding biological clock works for mice, not yet for humans
THE QUEST TO LIVE LONGER, fuller lives has captivated humanity for millennia. In lab mice, scientists have spent about a century studying the cellular damage that builds up in older animals and exploring ways to suppress the wear and tear. But around two decades ago, the goal posts changed.

Sweet! The Cell’s Sugary Coating Comes Into View
Published2 Jul 2026 Author Esther Landhuis Source Knowable Magazine iStock.com/Chinnachart Martmoh In the biological drama that is a cell’s life, you might think of DNA as the playwright, RNA as the director and proteins as the stars of the show. But life, and living things, are rarely so simple. It turns out that a less understood set of players — a crew of sugar structures known as glycans — gives added nuance and meaning to the action on the cellular stage.
Sleep and exercise may dampen genetic drivers of heart disease
Getting solid shut-eye and hitting the gym could offset the impact of some genetic mutations that raise the risk of heart disease and stroke. Mutations that accumulate in immune cells over a lifetime can intensify inflammation and promote cardiovascular disease, independent of traditional risk factors such as smoking, diabetes or high cholesterol. But sleep and exercise can weaken the harm of certain mutations, researchers report June 10 in Nature.
Book Review: The Case for Making Data-Driven Decisions
What guides an important decision? It might start with a core human emotion — fear, anger, a stubborn sense of hope. Some decisions draw from personal experience or from a gut feeling that a particular course of action is good and right. In such situations, decision makers typically trust the opinions of authorities and thought leaders and act according to their example. That is how societies and governments have operated for much of human history.

El glicoma: una mirada a la capa azucarada de la célula
En el drama biológico que es la vida de una célula, se podría pensar que el ADN es el guionista, el ARN el director y las proteínas las estrellas del espectáculo. Pero la vida, y los seres vivos, rara vez son tan simples. Resulta que un conjunto de actores menos conocidos —un grupo de estructuras de azúcar conocidas como glicanos— aporta matices y significado adicionales a la acción en el escenario celular.

The best way to help Alzheimer’s patients may be to help their caregivers
Programs that support caregivers of patients with dementia could bring substantial benefits at a fraction of the price of an Alzheimer’s drug. A computer simulation guided by patient data from prior studies found that supportive care reduced health care costs and scored higher than the drug intervention on a common measure of treatment value, researchers report February 5 in Alzheimer’s and Dementia: Behavior & Socioeconomics of Aging.
Alzheimer : des stratégies d’attaque sur tous les fronts
La maladie d’Alzheimer est un adversaire coriace. Pendant plusieurs décennies, chercheurs et entreprises pharmaceutiques se sont efforcés de trouver un traitement capable d’endiguer le déclin cognitif qui lui est associé, sans succès. Mais ce combat a pris un tournant significatif ces dernières années avec la mise sur le marché américain des premières thérapies ciblant les plaques amyloïdes.
Scientists shed new light on the brain's role in heart attack
Scientists at the University of California San Diego have discovered a path between the brain and the immune system that could potentially lead to new ways to ease heart attacks. They showed that disabling specific parts of that circuit could profoundly improve outcomes in mice with experimentally induced heart attacks. "The injury almost disappears," says UCSD neuroscientist Vineet Augustine, who led the new study appearing Tuesday in the journal Cell.
