The ability of the small intestine to absorb nutrients and act as a barrier to pathogens is significantly decreased after chronic exposure to nanoparticles of titanium dioxide, a food additive found in everything from chewing gum to bread, suggests research from Binghamton University, State University of New York. Researchers exposed a small intestinal cell culture…

Even Sticky Liquids Won’t Stick To This Surface
A new engineered surface can outperform some of nature’s best water repellents, including the leaves of the lotus flower. Creating surfaces that make liquid droplets more mobile could help prevent icing on aircraft wings and improve water harvesting in arid regions. Tak-Sing Wong, assistant professor of mechanical engineering at Penn State, says: This represents a…
