    A recent study, led by an international team confirms that targeted removal of senescent cells (SnCs), accumulated in many vertebrate tissues as we age, contribute significantly in delaying the onset of age-related pathologies. This breakthrough research has been led by Dr. Chaekyu Kim of the Johns Hopkins University School of Medicine, now at UNIST, and Dr. Ok Hee Jeon of the Johns Hopkins University School of Medicine in collaborations with the Mayo Clinic College of Medicine, the Buck Institute for Research on Aging, the University Medical Center Groningen, Unity Biotechnology, Inc., and the University of California, Berkeley.

    In the study, the team presented a novel pharmacologic candidate that alleviat...

A protein in the microbe that causes melioidosis, which occurs most often in people who live in tropical climates. Infection often starts in the lungs when contaminated dust or soil is inhaled.

    Not all onions are created equal. Engineering professor Suresh Neethirajan and PhD student Abdulmonem Murayyan tested 5 onion types grown in Ontario and discovered the Ruby Ring onion variety came out on top. Onions as a superfood are still not well known. But they contain one of the highest concentrations of quercetin, a type of flavonoid, and Ontario onions boasts particularly high levels of the compound compared to some parts of the world.

    The Guelph study revealed that the red onion not only has high levels of quercetin, but also high amount...

    Type of Sugar may Treat Atherosclerosis, mouse study shows

    June 7, 2017, Categories  Health/Medical, Biology/Biotechnology

    A new study shows that a type of natural sugar called trehalose triggers an important cellular housekeeping process in immune cells that helps treat atherosclerotic plaque. The image shows a cross section of a mouse aorta, the main artery in the body, with a large plaque. Straight red lines toward the upper left are the wall of the aorta. Yellow areas are where housekeeping cells called macrophages are incinerating cellular waste. Credit: Ismail Sergin

    Trehalose triggers cellular housekeeping in artery-clogging. Researchers have long sought ways to harness the body’s immune system to treat disease, especially cancer...
