Large day-to-day swings in temperature were associated with significantly more heart attacks in a study being presented at the American College of Cardiology’s 67th Annual Scientific Session. Given that some climate models link extreme weather events with global warming, the new findings suggest climate change could, in turn, lead to an uptick in the occurrence of heart attacks, researchers said.

More and more people are surviving cancer. Yet support for people who survive cancer and the research that underpins their care is insufficient, particularly when it comes to non-medical issues. A new special issue of the Journal of Cancer Policy, which will be published in March following the 3rd EORTC Cancer Survivorship Summit to be held in Brussels on March 1st and 2nd, shines a light on the issues and calls for more long-term research, better cross-analysis of different cancer types and better support for those who survive the disease.

A University of Calgary study of seasonal air pollution will be of cold comfort to thousands of Calgarians living south of the Bow River: that crisp, wintry air they’re breathing in is the worst in the city.

People who swim, bathe or take part in water sports in the sea are substantially more likely to experience stomach bugs, ear aches and other types of illness than those who do not.

A University of Guelph researcher has discovered one of the factors behind nerve cell death in Parkinson’s disease, unlocking the potential for treatment to slow the progression of this fatal neurodegenerative disorder.

Carbon monoxide can improve the effectiveness of antibiotics, making bacteria more sensitive to antibiotic medication, according to a study led by Georgia State University.

Chemical products like household cleaners, pesticides, paints and perfumes that contain compounds refined from petroleum now rival motor vehicle emissions as the top source of urban air pollution, according to a surprising NOAA-led study.

Humans and fruit flies may have not shared a common ancestor for hundreds of millions of years, but the neurons that govern our circadian clocks are strikingly similar.

Patients with terminal cancer face difficult decisions. What treatment options support their goals? When is it reasonable to discontinue care? A study published in the American Journal of Geriatric Psychiatry shows that these patients may be less competent to make these decisions than their doctors think.

The debate is over. Dietary protein supplements significantly improve muscle strength and size when taken by healthy adults who lift weights, a determination reached by McMaster scientists who analyzed dozens of research studies.
