Dengue vaccine shows effectiveness under real-world conditions during Brazil's 2024 outbreak

Forget the myth that exercise uses up your heartbeats. New Australian research shows fitter people use far fewer total heartbeats per day—potentially adding years to their lives.

Scientists from The Ohio State University Comprehensive Cancer Center—Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC–James) report key findings about the underlying mechanisms of immune system stress response to protein misfolding, launching a new approach to cancer immunotherapy treatment targeting the protein production cycle.

It's time to get a flu vaccine, and pediatricians are urging people to get them after last winter, when the U.S. saw the most flu-related child deaths in 15 years.

Fall is the time of year when thousands of Pennsylvania residents head to forests and woodlots with chainsaws to cut firewood to heat and enhance their homes over the coming winter months.

A recent study published in JAMA Network Open, titled "Health Care Professional Willingness to Treat Opioid Use Disorder vs. Type 2 Diabetes in Primary Care," reveals surprising insights into how primary care providers in Ohio perceive and treat opioid use disorder (OUD) differently from other chronic conditions, such as type 2 diabetes.

Several factors make ovarian cancer particularly challenging to treat. This is largely because the cancer often spreads at a microscopic level within the abdomen early on, resulting in diagnosis at an advanced stage. Additionally, while initial treatments with surgery, chemotherapy, and maintenance therapies are successful for many people, most advanced stage ovarian cancers eventually come back.

It's estimated that nearly half of adults aged 65 and older are living with prediabetes, a condition that predisposes them to developing type 2 diabetes and puts them at higher risk for cardiovascular complications.

When María Branyas Morera died in 2024 at the age of 117, she left more than memories. She left science a gift: samples of her microbiome.

New research published in JAMA Network Open finds that mailing human papillomavirus (HPV) self-sampling kits to patients is a cost-effective strategy for increasing cervical cancer screening completion rates. Long-term infection with high-risk HPV strains can cause abnormal cell growth, which could progress to cervical cancer. The study is the first to examine the cost-effectiveness of these mailing strategies across different patient screening histories within a U.S.-based health system.

Being able to instantly and accurately predict the trajectory of a person's health in the years to come has long been seen as the pinnacle of medicine. This kind of information would have a profound effect on health care systems as a whole—shifting care from treatment to prevention.

Could the secret to a longer, healthier life be hidden inside the brain of a fruit fly? Researchers at National Taiwan University (NTU) think the answer is yes.

Long-term exposure to the industrial solvent trichloroethylene (TCE) outdoors may be linked to an increased risk of Parkinson's disease, according to a large nationwide study published in Neurology.

A recent study has revealed significant variations in the nutritional composition of donor human milk across different countries. These findings could transform how hospitals support critically ill preterm infants worldwide.

A research team working at MedUni Vienna has demonstrated that a specific component of the immune system (PTX-3) remains at significantly higher levels in the blood of patients who have suffered from severe COVID-19, even months after the acute infection has subsided. This study identifies PTX-3 as a potential biomarker for existing tissue damage, long-term immune activation and also for complications following COVID-19.

Researchers at Stockholm University and Karolinska Institutet have found a system in the brain that can explain why female mice, who are not normally aggressive, suddenly and dramatically gain access to this behavior after becoming pregnant and giving birth (so-called maternal aggression).

A new Northwestern Medicine study has shed light on how a class of diabetes drugs may protect the kidneys—not just by lowering blood sugar, but by triggering a molecular shift that dampens inflammation, according to a study published in The Journal of Clinical Investigation.

At first glance, Alzheimer's disease and cancer have little in common. One erodes memory, while the other consumes the body. Yet researchers at MUSC Hollings Cancer Center have discovered an unexpected link connecting the two.

Erythropoietin (EPO) is primarily known to many as a hormone for blood formation. However, it has been known for some years that EPO also plays an important role in the brain—specifically where particularly demanding mental performance takes place.
