SAN FRANCISCO—Metabolic health factors, including small increases in blood sugar, are the main drivers of change in the reproductive systems and sexual functioning of aging men, according to a study being presented Saturday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. “Although age and testosterone levels have long been considered an impetus for men’s declining sexual health, our research indicates that these changes more closely correlate with modest increases in blood sugar and other metabolic changes,” said Michael Zitzmann, ...

SAN FRANCISCO—Strong emotional links between children with chronic conditions and their family caregivers suggest that improving parent well-being may directly benefit a child’s overall health and coping mechanisms, according to a study being presented Saturday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. The study observed children with growth hormone deficiency and their caregivers to better understand the impact that physical or emotional distress can have. Findings suggest that when parents or caregivers of children with growth hormone deficiency report symptoms of stress, anxiety and depression, so does the child they ...

SAN FRANCISCO—Oxytocin, often called “the love hormone,” may play a protective role in mood disturbances triggered by sleep loss and hormonal shifts during key reproductive transitions like postpartum and menopause, according to a study being presented Saturday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif. Researchers at Brigham and Women’s Hospital and Harvard Medical School studied the combined impact of sleep interruption and estrogen suppression on mood and oxytocin levels in healthy premenopausal women. Their findings suggest that oxytocin may help reduce the negative mood effects brought on by fragmented sleep, which ...

SAN FRANCISCO—The anti-obesity medication tirzepatide, marketed as Mounjaro for diabetes and Zepbound for obesity, reduced obesity-associated breast cancer growth in a mouse model, according to a study being presented Saturday at ENDO 2025, the Endocrine Society’s annual meeting in San Francisco, Calif.

Despite a warming climate, bone-chilling winter cold can grip parts of the U.S.—and this study explains why. Researchers found that two specific patterns in the polar vortex, a swirling mass of cold air high in the stratosphere, steer extreme cold to different regions of the country. One pattern drives Arctic air into the Northwest U.S., the other into the Central and Eastern areas. Since 2015, the Northwest has experienced more of these cold outbreaks, thanks to a shift in stratospheric behavior tied to broader climate cycles. In short: what happens high above the Arctic can shape the winter on your doorstep. As winters in the United States continue ...

Scientists have discovered how a key protein helps maintain strong connections between brain cells that are crucial for learning and memory.

Their research, led by a Rutgers University-New Brunswick professor, uncovered a previously unknown role for cypin, a brain protein. Members of the research team found that cypin promotes the presence ...

Hollywood has shaped how many people imagine a heart attack—someone clutching their chest and collapsing dramatically. But those portrayals are misleading and shouldn’t be expected, says Ann Eckhardt, a nursing professor and researcher at The University of Texas at Arlington. “We did ourselves a disservice in the 1980s and 1990s with what’s known as ‘The Hollywood Heart Attack,’” Dr. Eckhardt said. “That’s unfortunately not real life. It’s not always intense. Sometimes it’s just discomfort that doesn’t feel quite ...

The International Human Frontier Science Program Organization (HFSPO) is pleased to award the 2026 HFSP Nakasone Award to Erin Schuman for her breakthrough related to the function and plasticity of neuronal synapses, their mRNA triggered function, and change during memory formation. Schuman’s groundbreaking research revealed that proteins critical for neuron communication, plasticity and memory storage, are produced locally at synapses, the junctions between neurons. This insight overturns the previous belief that all proteins are made in the cell body and then shipped out to synapses where they function. “HFSPO is thrilled to honor Dr. Erin Schuman as her discovery is influencing ...
