In a study published in the journal Environmental Science & Technology, WashU researchers discovered that a common mineral called goethite — an iron-rich mineral that is abundant in soils that cover the Earth — tends to incorporate trace metals into its structure over time, binding the metals in such a way that it locks them out of circulation.

Zinc Transporter Has Built-in Self-regulating Sensor
Scientists at Brookhaven Lab have determined the atomic-level structure of a zinc-transporter protein, a molecular machine that regulates levels of this crucial trace metal micronutrient inside cells. The structure reveals how the cellular membrane protein shifts its shape to move zinc from the environment into a cell, and temporarily blocks this action automatically when zinc levels inside the cell get too high.
Decline of Bees, Other Pollinators Threatens U.S. Crop Yields
Crop yields for apples, cherries and blueberries across the United States are being reduced by a lack of pollinators, according to Rutgers-led research, the most comprehensive study of its kind to date. Most of the world’s crops depend on honeybees and wild bees for pollination, so declines in both managed and wild bee populations raise concerns about food security, notes the study in the journal Proceedings of the Royal Society B: Biological Sciences.
Unfruitful: Eating More Produce Will Not Cure, Stop Prostate Cancer
University of California San Diego School of Medicine researchers report that patients with prostate cancer assigned to eat seven or more servings of vegetables and fruits daily saw no extra protection from the increased consumption of micronutrients, running contrary to current thought.
Life-saving test for nutrient deficiency designed to perform in harsh environments
Mothers and children in low resource communities often suffer from micronutrient deficiencies. Now researchers have developed a system that can be used for tests to rapidly identify blood micronutrient levels in remote areas with limited healthcare infrastructure.
