Aging reshapes the ovary long before reproductive function ends
Aging affects every organ in the body, yet we still know little about how the ovary changes over time. In a new study published in Nature Aging, Yale researchers created one of the most detailed maps of the aging ovary to date, examining how its cellular organization changes acro
Youth tobacco use falls, but flavored e-cigarettes are still a concern
The U.S. Food and Drug Administration (FDA) this week shared findings from the 2025 National Youth Tobacco Survey (NYTS). The American Heart Association has issued the following statement:
Gut-homing antibodies help protect against norovirus, paving path for new vaccines, therap
As the leading cause of viral gastroenteritis worldwide, norovirus is an all too familiar ailment. Its telltale digestive upset—not to mention its reputation for being notoriously contagious—has earned it the nicknames "winter vomiting bug" and "stomach flu." Yet despite millions
Uneven cerebellum aging may partly explain why some older adults stay mentally sharp
Scientists may have discovered a new role for the cerebellum, the part of the brain that sits at the base of the skull. A new paper published in the journal Nature Neuroscience reports that different parts of the cerebellum change at different rates with age, which may be linked
Genomic tool highly effective at detecting rare disease diagnoses
A newly developed open-source tool designed for rigorous reanalysis of genomic data is highly effective at detecting new rare disease diagnoses. The tool's ability to frequently and automatically reexamine stored DNA data will ensure more timely answers for hundreds of families.
Hidden mechanism driving joint tissue growth in rheumatoid arthritis has been found
Researchers at Hospital for Special Surgery (HSS) have identified a specialized population of immune cells that plays a central role in driving abnormal tissue growth in rheumatoid arthritis (RA), offering new insight into disease progression and potential treatment strategies. T
Simple eye scan in preterm infants may help predict brain development
Very preterm infants face up to a 50% higher risk of developmental challenges affecting movement, learning, language and behavior. Today, many of those challenges are not fully recognized until later in infancy or early childhood. Doctors have lacked reliable tools to identify wh
Personalized brain imaging may improve outcomes for treatment-resistant depression
A new randomized clinical trial from investigators at Mass General Brigham's Neuroscience Institute and Department of Psychiatry suggests that using personalized brain imaging to guide transcranial magnetic stimulation (TMS) may improve outcomes for people with treatment-resistan
How zebrafish might be key to unlocking treatments for hereditary disease CADASIL
CADASIL, which stands for "cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy," is a hereditary disease that damages the brain's small blood vessels, causing recurrent strokes. Over time, CADASIL leads to a decline in cognitive function and
Silk sticker is noninvasive way to monitor babies' health
In the neonatal intensive care unit, the most fragile patients in medicine are often the most heavily wired. Premature babies, some weighing less than a pound, can be tethered to a tangle of cables, monitors and sensors. Each blood draw to check sugar levels or electrolytes means
Genetic testing projected to increase ALS clinic visits over next decade
The availability of genetic testing for amyotrophic lateral sclerosis (ALS) for people with a family member diagnosed with the disease is expected to greatly increase the number of clinic visits to specialized ALS centers over the next decade, according to a study published in Ne
