Toxic Nanoparticles Might be Entering Human Food Supply, MU Study Finds

Scientists develop new way to detect threatening nanoparticles in food

COLUMBIA, Mo. – Over the last few years, the use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industries has increased. For example, farmers have used silver nanoparticles as a pesticide because of their capability to suppress the growth of harmful organisms. However, a growing concern is that these particles could pose a potential health risk to humans and the environment.  In a new study, researchers at the University of Missouri have developed a reliable method for detecting silver nanoparticles in fresh produce and other food products.

“More than 1,000 products on the market are nanotechnology-based products,” said Mengshi Lin, associate professor of food science in the MU College of Agriculture, Food and Natural Resources. “This is a concern because we do not know the toxicity of the nanoparticles. Our goal is to detect, identify and quantify these nanoparticles in food and food products and study their toxicity as soon as possible.” (more…)

Slinky Science Inspires African School Children

A University of Exeter physicist has inspired hundreds of African school children to engage with science during a whirlwind outreach tour to Malawi.

Professor Pete Vukusic used simple interactive demonstrations including slinky springs, glass prisms, light sticks and iridescent butterflies to enthral large classes of pupils and teachers in underprivileged rural schools.

The charismatic lecturer combined use of the demos and an interactive and engaging teaching style to explain fundamental and modern science principles to students who are used to formal instructional teaching methods. Professor Vukusic hopes his visit will both help to inspire science learning in these schools and help their teachers adapt to more modern techniques that engage young people more effectively.
