While thoughts and deeds are clearly different, University of Houston professor of psychology Rheeda Walker has examined both and finds that current approaches to suicide prevention are troubling, because they usually consist

Synthetic cells capture and reveal hidden messages of the immune system

When immune cells detect harmful pathogens or cancer, they mobilise and coordinate a competent defence response. To do this effectively immune cells must communicate in a way that is tailored to the pathogenic insult. Consequently, the body’s response to various health challenges depends on successful coordination among the cells of the immune system. Key players

The rise of ‘eco-anxiety’: Climate change affects our mental health, too

The Australian Medical Association (AMA) recently declared climate change a health emergency, reflecting similar positions taken by a growing list of peak medical bodies around the world. The AMA’s statement highlights the significant impacts climate change is having on physical health, including an increase in climate-related deaths.

Ranitidine stomach acid blockers with cancer-causing substances contaminated

After the scandal of contaminated blood-pressure-lowering drug with the active ingredient Valsartan in the past year, the potentially cancer-causing substances, called nitrosamines were found in other medicines. It is a stomach acid blocker ranitidine. German products are affected.

Vitamin E found to prevent muscle damage after heart attack

Heart attack is a leading cause of death worldwide and new treatment strategies are highly sought-after. Unfortunately lasting damage to the heart muscle is not uncommon following such an event. Published in Redox Biology, the pre-clinical study sheds new light on the potential of the acute therapy with ?-TOH (vitamin E) in patients presenting with

Gene-targeted cancer drugs, slow release overcome resistance

Biomedical engineers at Duke University have developed a method to address failures in a promising anti-cancer drug, bringing together tools from genome engineering, protein engineering and biomaterials science to improve the efficacy, accuracy and longevity of certain cancer therapies. Using a combination of CRISPR-based targeting, a protein “depot” that allows for sustained release of the

Anemia may contribute to the spread of dengue fever

Mosquitoes are more likely to acquire the dengue virus when they feed on blood with low levels of iron, researchers report in the 16 September issue of Nature Microbiology. Supplementing people’s diets with iron in places where both iron deficiency anemia and dengue fever are a problem could potentially limit transmission of the disease, but

Few people with peanut allergy tolerate peanut after stopping oral immunotherapy: Continuing with a modest dose confers more protection

Allergy to peanut, which is often severe, is one of the most common food allergies in the United States. Although previous studies have shown that peanut oral immunotherapy (OIT) — ingesting small, controlled amounts of peanut protein — can desensitize adults and children and prevent life-threatening allergic reactions, the optimal duration and dose is unknown.

Claims supplements could ‘balance’ hormones in menopause criticised

Olympian Lisa Curry has drawn sharp criticism from health experts for implying women should avoid prescribed hormone replacement therapy and use supplements, which she sells. A statement released by the former champion swimmer to promote a TV appearance said hormone therapy had been "proven to increase women's risk of breast cancer", and promoted "natural" treatments
