AI-assisted technique can measure and track aging cells

Our metabolic processes differ depending on the time of day and many of them are more active in the morning than in the evening. Although studies show that eating late in the day is associated with an increased risk of obesity and cardiovascular diseases, little is known about how the time we eat affects glucose metabolism and to what extent this is genetically defined.

As my term as acting WHO regional director for Africa draws to a close, I have been reflecting on the resilience and collective commitment that have defined our region's fight against polio.

The skeletal muscles of men and women process glucose and fats in different ways. A study conducted by the University Hospital of Tübingen, the Institute for Diabetes Research and Metabolic Diseases of Helmholtz Munich and the German Center for Diabetes Research (DZD) e.V. provides the first comprehensive molecular analysis of these differences. The results, published in Molecular Metabolism, possibly give an explanation for why metabolic diseases such as diabetes manifest differently in women and men—and why they respond differently to physical activity.

As the United States reflects on the 50th anniversary of the end of the Vietnam War this year, researchers from UC Davis and UC San Francisco have uncovered major insight into the trauma and resilience of Vietnamese Americans who fled the conflict and moved to America.

While immunosuppressive medications are critical to preventing rejection of transplant organs, they also come with plenty of downsides. They can cause harsh side effects, like headaches and tremors, and increase the risk of infection and cancer. But what if there was a way to prevent organ rejection without using these medications?

Women with kidney transplants who use assisted reproductive technology (ART) to conceive might face higher risks of complications during pregnancy, according to new research from the University of Cincinnati College of Medicine. The study provides some of the first large-scale data on pregnancy outcomes in this unique patient population.

Nearly half of cannabis flower products are inaccurately labeled when it comes to potency, with most showing they contain more THC than they really do. Meanwhile, labels on cannabis concentrates like oils and waxes tend to be accurate, with 96% shown to match what's inside.

A new study has found that people from non-white ethnic backgrounds in England and Wales continued to be disproportionately impacted by severe outcomes after COVID-19 such as cardiovascular disease.

Targeted cancer drugs known as CDK4/6 inhibitors have improved outcomes for patients with advanced or metastatic HR+/HER2- breast cancer, but many patients still eventually relapse and become resistant to therapy. New research co-headed by a Fox Chase Cancer Center scientist helps explain why—and offers three strategies for making treatment more effective.

For over a century, surgeons performing delicate procedures have relied on stereoscopic microscopes to gain a sense of depth. These tools mimic human vision by presenting slightly different images to each eye, allowing the brain to perceive three-dimensional structures—a crucial aid when working with fragile blood vessels or intricate brain tissue. Despite modern upgrades like digital displays and video capture, today's operating microscopes still depend on the same core principle: two views, interpreted by the human brain.

Researchers have found that the timing of when fluoxetine (commonly known by its brand name, Prozac) is administered is vital in determining the impact it has on long-lasting mood behavior and accompanying changes in the prefrontal cortex. The new study published in Biological Psychiatry provides crucial mechanistic insights into alterations in neurocircuits that regulate mood behavior, which are key to making informed choices in treating depression in children and adolescents.

"Are we stopping again already?" It's a familiar complaint on family road trips and one that's often aimed at women. From sitcoms to stand-up routines, the idea that women have smaller bladders has become a cultural punchline. But is it anatomically accurate?

The United States in 2025 has recorded its worst measles epidemic in more than 30 years, according to a count released Monday by Johns Hopkins University, highlighting a crisis that President Donald Trump's vaccine-skeptic US health secretary is accused of fueling.

The health of U.S. children has deteriorated over the past 17 years, with kids today more likely to have obesity, chronic diseases and mental health problems like depression, a new study says.

A new study from the University of Colorado Anschutz Medical Campus, published in F&S Reports, reveals that individuals living with Polycystic Ovary Syndrome (PCOS) often feel dismissed, misunderstood and underserved by the health care system.

In recent years, the analysis of single-cell and spatial data has revolutionized biomedical research, making it possible to observe what happens in biological samples with an unprecedented level of detail. Interpreting this data, however, is not easy because different software offers different results which are hard to compare.

Researchers at the University of California San Diego have completed a landmark survey of more than 5,000 Californians to study the effects of Proposition 64: The Adult Use of Marijuana Act, which made recreational cannabis use legal for adults 21 years of age and older across the state in 2016.

Higher summer temperatures are resulting in more children seeking emergency care for heat-related illnesses, with nearly 1 in 5 needing hospitalization, according to new research from UT Southwestern Medical Center published in Academic Pediatrics.
