US approves twice-yearly injection for HIV prevention. What you need to know about lenacapavir

The number of women using medicinal cannabis is growing in New Zealand and overseas. They use cannabis treatment for general conditions such as pain, anxiety, inflammation and nausea, as well as gynecological conditions, including endometriosis, pelvic floor conditions, and menopause.

A novel PET radiotracer can accurately detect a wide range of mold species that are linked to dangerous infections, according to new research presented at the Society of Nuclear Medicine and Molecular Imaging 2025 Annual Meeting and published in the Journal of Nuclear Medicine.

A novel molecular imaging agent targeting glypican-3 (GPC3) has demonstrated high sensitivity and specificity in detecting hepatocellular carcinoma (HCC), including tumors smaller than one centimeter, according to results from a pilot clinical study.

Researchers from Osaka Metropolitan University have identified a gene that, when activated by metabolic stress, damages pancreatic β-cells—the cells responsible for insulin production and blood sugar control—pushing them toward dysfunction. The findings highlight a promising new target for early intervention in type 2 diabetes. The study is published in the Journal of Biological Chemistry.

A pretreatment step could help transplanted pancreatic islets survive longer in patients with type 1 diabetes, according to a new preclinical study from Weill Cornell Medicine investigators. One combination of small molecules extended the cells' lives in female mice, and adding two molecules to the mixture boosted cell survival in male mice.

Researchers have pinpointed the precise pathway in the brain that suppresses pain in times of threatening situations.

The Association of Southeast Asian Nations (ASEAN) has consistently taken a proactive role in controlling tuberculosis (TB) in the region. But with Southeast Asia accounting for a significant share (45%) of global TB cases, the fight remains a long and winding road.

New research with University of Cincinnati connections debunks the standard assumption of disordered eating and proposes more personalized attention.

Imagine itching, burning, swelling, or even struggling to breathe just moments after sex. For a small but growing number of women, that's not an awkward anecdote—it's a medical condition. It's called seminal plasma hypersensitivity (SPH)—an allergy to semen.

Mosquito-borne dengue fever was rarely a major problem in Bangladesh's coastal districts, but some hospitals are so full of those with the potentially deadly virus that patients are treated on the floor.

New research has shown that simply telling people whether their drinking water is safe can lead to major improvements in health behavior, even without household equipment or financial help.

Many smartwatches, fitness and wellness trackers now offer sleep tracking among their many functions.

Opioids like fentanyl, morphine and oxycodone are the drugs most linked to overdoses in the U.S. Typical screening methods for drug usage involve collection of blood, saliva or urine samples. Now, in Analytical Chemistry, researchers demonstrate a pen-like tool that can quickly and non-invasively collect molecules from the skin's surface to be screened for opioids with mass spectrometry.

Have you had a tonsillectomy (your tonsils taken out), appendectomy (your appendix removed) or lumpectomy (removal of a lump from your breast)? The suffix "ectomy" denotes surgical removal of the named body part, so these terms give us a clear idea of what the procedure entails.

Using stem cells from patients with ALS (amyotrophic lateral sclerosis), Cedars-Sinai has created a lifelike model of the mysterious and fatal disease that could help identify a cause of the illness as well as effective treatments.

Going off to summer camp can be a scary experience for children, but it can be even more nerve-wracking for parents of kids with food allergies. New UVA Health research reveals the most cost-effective way to keep those children safe.

Cars may be a modern phenomenon, but motion sickness is not. More than 2,000 years ago, the physician Hippocrates wrote "sailing on the sea proves that motion disorders the body." In fact, the word nausea derives from the Greek "naus," meaning ship.

Temperatures have dropped in many parts of Australia, which means runners, cyclists, rowers, hikers, or anyone physically active outside need to take extra precautions to stay safe and exercise in relative comfort.
