Shiga toxin-producing Escherichia coli (STEC) is a bacterium that can cause bloody diarrhea. One in five infected children experience life-threatening complications. In summer 2023, a large STEC outbreak occurred at several Calgary daycare centers. https://medicalxpress.com/news/2026-03-daily-blood-curb-coli-complications.html Wed, 11 Mar 2026 17:10:02 EDT news692467741 Strong social networking plays an important role in human relationships. New research on female red deer shows that those bonds are also crucial for their reproductive success and survival. The study, which looked at more than 40 years of data for free-ranging adult female red deer on the Isle of Rum in Scotland, was recently published in Royal Society Open Science. https://phys.org/news/2026-02-mother-daughter-bonds-red-deer.html Plants & Animals Thu, 19 Feb 2026 13:20:05 EST news690725496 Edward (Ed) Waldner had no idea why he didn't feel well, but he knew he didn't feel like himself.

In 2022, Krebs experienced a severe spinal cord injury (SCI) in a motor vehicle accident. Since that time, Krebs requires the use of a wheelchair. The damage to his spinal cord means his brain can no longer control blood pressure in his body. He was vulnerable to blood pressure drops where he was at risk of losing consciousness, and spikes placing him at risk of a heart attack and stroke. https://medicalxpress.com/news/2025-09-implantable-neurostimulation-blood-pressure-spinal.html Neuroscience Wed, 17 Sep 2025 15:53:04 EDT news677343181 Researchers at the University of Calgary studying a lethal lung disease called pulmonary fibrosis have found that neurons known to help detect pain are also critical for reducing harmful lung inflammation that leads to the disease. https://medicalxpress.com/news/2025-09-pain-nerve-cells-yield-lung.html Immunology Tue, 16 Sep 2025 16:04:04 EDT news677257442 Most children seeking emergency department (ED) care due to vomiting are discharged home.
