Potential biomarker for the development of long COVID identified

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.

An international team of researchers has demonstrated that the tetravalent dengue vaccine known as Qdenga provided significant protection against the disease under real-world conditions, during the large 2024 epidemic in São Paulo, Brazil.

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.

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.

Some people with autism spectrum disorder (ASD) have abnormal levels of glutamate in the brain. New research led by Mass General Brigham has focused on this neuron-activating chemical, suggesting that a glutamate-modulating drug called memantine may improve social functioning in youth with ASD who do not have intellectual disabilities.

In a preclinical study, UC Davis Comprehensive Cancer Center scientists have developed a highly targeted gene therapy that could revolutionize treatment for cancers linked to a common herpesvirus, with minimal side effects.

Two distinct stem cell lineages that drive tooth root and alveolar bone formation have been identified by researchers from Science Tokyo. Using genetically modified mice and lineage-tracing techniques, the team has shed light on the cell signaling mechanisms guiding differentiation in stem cells in the developing teeth, offering key insights for future regenerative dental therapies.

For years, virtual reality (VR) has been used in pain management for hospitalized adults and children, to take their minds off their discomfort, but typically the technology has been a solo experience for the patient.

Certain nutrients in food can trigger a mild stress response in nematodes. But instead of making them sick, this actually helps them stay healthier as they age, according to researchers at the University of Basel, Switzerland.
