Is sleeping a lot actually bad for your health? A sleep scientist explains

Use of billing codes in big data sets to find diagnoses can result in up to two-thirds of cases being mistakenly identified, new UCLA-led research finds.

Eight essential nutrients make up the suite of B vitamins also known as the B complex. Research at Tufts and elsewhere has revealed that these B vitamins influence a vast spectrum of human health and disease, including cognitive function, cardiovascular health, gastric bypass recovery, neural tube defects, and even cancer.

Nearly half of Virginia's neighborhoods don't have enough nearby primary care physicians for their residents, with rural communities being hit hardest by workforce shortages, according to a new study led by researchers at Virginia Commonwealth University.

University of Utah Health researchers have documented an association between air pollution exposure and a rare type of bleeding within the brain. An aneurysmal subarachnoid hemorrhage, or aSAH, can damage brain tissue enough to leave patients paralyzed or in a coma or cause death.

Endometrial cancer—in which tumors develop in the inner lining of the uterus—is the most prevalent gynecological cancer in American women, affecting more than 66,000 women a year. Black women are particularly at risk, with an 80% higher mortality rate than other demographic groups and a greater chance of contracting more aggressive cancer subtypes.

Your fitness tracker might be lying to you. That 10,000-step target flashing on your wrist? It didn't come from decades of careful research. It came from a Japanese walking club and a marketing campaign in the 1960s.

A new report has revealed that the North of England has some of the poorest diets in the country, putting the population at risk of conditions such as obesity, high blood pressure and other preventable diseases.

In elite sport, the phrase "past your prime" is rapidly being redefined.

A new study shows that while decentralized clinical trials (DCTs) are making research more accessible, they also bring challenges for research staff that can increase clinical staff workload, negatively impact the patient experience, and impact trial delivery.

Most sports look to support their athletes to become "faster, higher, stronger"—in reference to the Olympic Games' original motto—so it is perhaps surprising that cycling's world governing body is trying to slow down elite riders.

A study published in Eurosurveillance has found evidence of substantial lifetime exposure to hepatitis B and C viruses in Ukraine in a 2021 nationwide, representative sample of the population, with findings also suggesting significant ongoing circulation of these viruses.

When actor Orlando Bloom revealed recently that he'd undergone a procedure to have his blood "cleaned," many people raised eyebrows. The "Pirates of the Caribbean" star had turned to a treatment known as apheresis—a medical process in which blood is removed from the body, centrifuged or filtered to extract certain components, then returned in an attempt to flush out microplastics and other toxins.

Two teenage boys were thrown from a jet ski during a ride on the Georges River in Sydney's south this week. One died at the scene. The other lost an arm, and was rushed to hospital in a serious condition.

Hospitalizations and emergency department (ED) visits can be distressing and costly for nursing home residents—especially those who are severely impaired or terminally ill. Despite their vulnerability, these individuals are frequently transferred to hospitals, even though up to 40% of such transfers over the past 25 years are considered potentially avoidable by health care professionals.

Every time Ashton Alexander sees an ad for Georgia Pathways to Coverage, it feels like a "kick in the face."

Brain-computer interfaces (BCIs)—implantable medical devices used to treat neurological conditions—are becoming increasingly sophisticated, making them more vulnerable to cyberattacks.

A research team has identified STAT1 as a key transcriptional regulator that enhances platelet production from induced pluripotent stem (iPS) cells by epigenetically controlling LIN28A and its downstream let-7-RALB axis. The study, published in Blood Advances, was led by Dr. Si Jing Chen (Chiba University) and Professor Koji Eto (Department of Clinical Application)

TherVacB, a therapeutic vaccine for chronic hepatitis B, has entered its first clinical trial in patients. The first patient was enrolled in June 2025 and treated with the vaccine. In a previous trial in healthy volunteers, the vaccine demonstrated a favorable safety profile and triggered the desired immune responses.
