Community water fluoridation works: Experts debunk myths, highlight lifelong benefits

Imagine it's Saturday morning, the perfect time to slow down, relax and... pay off debt? That's how many Americans start their weekend. No, we're not talking about the credit card bill. Many Americans are in debt—sleep debt.

A tiny molecule called a nanobody may succeed where today's cancer drugs often fail, according to University of Hawaiʻi at Mānoa researcher Stefan Moisyadi, who has been refining the concept for nearly a decade.

A new gene therapy approach aimed at protecting people with type 1 diabetes from developing diabetic kidney disease—a serious and common complication of the condition, has shown promising results in a University of Bristol study.

An AI system that can predict what a patient's knee X-ray will look like a year in the future could transform how millions of people with osteoarthritis understand and manage their condition, according to research by the University of Surrey.

What if scientists could build a realistic model of the human lung, not full-sized, but grown in the lab from living cells? Why would they do this? VIDO scientists based at the University of Saskatchewan have been exploring exactly that, and their work shows that these small, 3D structures referred to as "organoids" behave much like real lungs, giving scientists a powerful new way to study how viruses infect us.

The NHS incurs an estimated £340 million in additional health care costs annually due to weight-related health problems in children—but it is not just obesity driving the costs. New research from the University of Oxford reveals that underweight children need comparable medical support as those who are severely obese, challenging assumptions about childhood health priorities.

At the American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) 2025 Annual Meeting & OTO EXPO, leading experts presented findings today from a pioneering feasibility study exploring how clinical practice guidelines (CPGs) can be adapted for the digital age through computable formats.

One in four sexually active women has used injectable birth control, administered into the muscle by a clinician, but many may be unaware of its association with meningioma, the most common brain tumor in adults. In Europe and Canada, the drug is mandated to carry a warning—but not in the U.S.

The complex sugar molecules that festoon our cells are often treated as little more than biological decoration. A new study suggests they hold hidden patterns—distinct signatures that can separate one cancer from another. The paper is published in the journal Cell Reports Methods.

Psilocybin could be the future of mental health care, with promising findings emerging from Australia's first research trial using psychedelics to treat depression, led by Swinburne University of Technology.

October is Breast Cancer Awareness Month, and cancer awareness starts with general breast awareness. Dr. Julie Nangia, medical director of breast oncology at the Dan L Duncan Comprehensive Cancer Center, recommends monthly breast self-exams to stay aware of changes in the breast that could be cancer. She explains warning signs women should look for.

Health officials in several states are battling new measles outbreaks that have forced hundreds of unvaccinated students into quarantine.

More than a million people around the world rely on cochlear implants (CIs) to hear. CI effectiveness is generally evaluated through speech recognition tests, and despite how widespread they are, CI sound quality is typically not considered an indicator of users' quality of life.

The idea that you can "catch" shingles is one of the more common misconceptions I hear from patients who arrive worried they've got it. Often, they've recently been near a child with chickenpox or someone else with shingles, and are understandably anxious they've picked it up.

UC Berkeley's Rikky Muller (Ph.D.'13 EECS), associate professor of electrical engineering and computer sciences, can still recall her first glimpse into the world of neurotechnology. At a conference nearly two decades ago, she saw something that didn't seem possible: chips recording neural signals from the brain, then using those signals to control robotic arms.

About 1 in 3 Australian adults (32%) has a body-mass index (BMI) of 30 or above. A further 34% has a BMI of 25 or above.

Researchers in Sweden are testing a 250-year-old medicine in patients with one of the world's deadliest cancers.

Time—or the lack of it—could be a missing link in dementia prevention, according to a new paper from UNSW Sydney's Center for Healthy Brain Aging (CHeBA).
