Researchers at Harvard Medical School, the Broad Institute of MIT and Harvard and Brigham and Women’s Hospital have uncovered a genetic mechanism that helps drive clonal hematopoiesis, a common age-related condition known to increase the risk of blood cancer and cardiovascular disease. In clonal hematopoiesis or CH, some blood stem […]

A study from the National Institutes of Health showed that neurofilament light chain (NfL) delivered a superior diagnostic and prognostic performance as a blood biomarker for mild, moderate, and severe traumatic brain injury (TBI) when compared to blood proteins glial fibrillary acidic protein, tau, and ubiquitin c-terminal hydrolase-L1. The research […]

The disposibility theory of aging is one of numerous evolutionary theories of aging that seek to explain why aging exists and is near universal across species. In this case, aging is viewed as the inevitable result of trade-offs between resources allocated to reproduction versus resources allocated to tissue maintenance. Like […]

One of the most common misconceptions is that one human year equals seven dog years in terms of aging. However, this equivalency is misleading and has been consistently dismissed by veterinarians. A recent study, published in the journal Cell Systems(link is external), lays out a new framework for comparing dog-to-human aging. In […]

Research by the universities of Liverpool and Oxford reveals new insight into age-related fertility decline in male fruit flies. Infertility is one of the most striking effects of ageing. The impact of ageing on females’ fertility is more severe and much better understood, but it also affects males. Male reproductive […]

First study of its kind shows formula-fed babies’ gut microbiomes more like those of breastfed babies when they live near natural environments. Living close to natural green space can mitigate some of the changes in infant gut bacteria associated with formula feeding, according to new research published in the journal Environment International. “Not […]

Volunteers can add data with a five-minute online session. Do you get nervous when you can’t think of a word? Chances are it’s a momentary lapse, but problems with language are one of the symptoms that can indicate a neurodegenerative disorder like Alzheimer’s disease. Unfortunately, diagnosing these conditions requires scoring […]

A new study from Penn Medicine lends further evidence that the social behaviors tied to autism spectrum disorders (ASD) emerge from the abnormal function of sensory neurons outside the brain. It’s an important finding, published in the journal Cell Reports because peripheral sensory systems—which determine how we perceive the environment around us […]

To make new memories, our brain cells first must find one another. Small protrusions that bud out from the ends of neurons’ long, branching tentacles dock neurons together so they can talk. These ports of cellular chatter – called synapses, and found in the trillions throughout the brain – allow […]

A new model of the causes of breast cancer, created by a team led by researchers at UC San Francisco, Genentech and Stanford University, is designed to capture the complex interrelationships between dozens of primary and secondary breast cancer causes and stimulate further research. Breast cancer is the most common […]

Black men in the United States are known to suffer disproportionately from prostate cancer, but few studies have investigated whether genetic differences in prostate tumors could have anything to do with these health disparities. Now, in the largest study of its kind to date, researchers from Boston University School of […]

A little-studied liver protein may be responsible for the well-known benefits of exercise on the aging brain, according to a new study in mice by scientists in the UC San Francisco Eli and Edythe Broad Center for Regeneration Medicine and Stem Cell Research. The findings could lead to new therapies to […]
