Cornell food scientists hunting for a stable, natural red food coloring to replace artificial dyes have unlocked a secret: Use beet extract and pair it with a starchy partner, according to research published Feb. 8 in the journal Food Hydrocolloids.

In Nigeria, 75 percent of preschool children and 67 percent of pregnant women are anemic, and 20 percent of children below five years suffer from zinc deficiency. Iron deficiency anemia affects the immune system, stunts growth and impairs cognitive development in children, while deficiency in zinc causes increased risk of death from diarrhea, stunting and reduced cognitive development. Developing new varieties of a staple food crop with elevated levels of these two minerals could significantly improve diets and health.

Micronutrient deficiency, sometimes called the “hidden hunger,” causes severe health problems in hundreds of millions of people worldwide, and is particularly damaging to children, in whom it can impair both physical and cognitive development.  Biofortification is one of the most promising tools available for alleviating this problem, but is a multifaceted challenge involving not only creating nutrient-rich crop varieties, but also ensuring bioavailability of these nutrients, protecting against increased uptake of toxins such as cadmium, and adoption by affected populations.

Fourteen months ago, Lt. Gov. Kathy Hochul came to the Cornell High Energy Synchrotron Source (CHESS) to announce a $15 million grant from the New York State Upstate Revitalization Initiative.

Application deadline for Summer 2019 is February 15, 2019.

ITHACA, N.Y. — Construction crews have completed “significant upgrades” totaling $15 million at the Cornell High Energy Synchrotron Source, or CHESS, a scientific-research facility in Ithaca

Understanding the behavior of metals undergoing deformation is critical to design for fuel efficiency, performance and safety/crashworthiness. Traditional engineering analysis treats metal deformation as a smooth motion, like a fluid, when in reality the flow is intermittent at finer length scales.  Use of a new detector enabled the study of these intermittent bursts of deformation at the scale of individual crystals in a loaded test sample.

Proteins are molecular machines that participate in the vast majority of activities that occur in any living system.  To carry out their functions, they undergo dynamic changes in structure and shape and interact with other molecular systems.  Characterizing these intramolecular motions provides insight into the molecular basis of protein function and, in turn, can result in a deeper understanding of a vast range of physiological functions.
