Red Onions pack a Cancer-fighting punch, study reveals

Abdulmonem I. Murayyan, Cynthya M. Manohar, Gordon Hayward, Suresh Neethirajan. Antiproliferative activity of Ontario grown onions against colorectal adenocarcinoma cells. Food Research International, 2017; 96: 12 DOI: 10.1016/j.foodres.2017.03.017

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...

Sea Urchin Protein provides insights into Self-Assembly of Skeletal Structures

Researchers are investigating a protein found inside the spicules of a sea urchin embryo to understand what makes these proteins such efficient ‘brick organizers’. Calcium carbonate, or CaCO3, comprises more than 4% of Earth’s crust. Its most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. NYU Dentistry researchers are studying how nature creates 3D CaCO3 inorganic/organic based materials to form seashells, invertebrate exoskeletons, and vertebrate bone, dentine, and enamel.

Type of Sugar may Treat Atherosclerosis, mouse study shows

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...
