Providing Peace of Mind: Ultra Low-Level Detection of Pesticides in Baby Food

Blog

Pesticides are widely used to protect food crops from damage and consequently have the potential to end up in the food we eat. Young children and babies can be particularly susceptible to pesticide residues in food so testing for pesticide residues in food, and baby food in particular, is therefore critical for the preservation of human health.

8 Top Tips For Pesticide Screening

List

Pesticides help to maximise food crop production however, the potential for them to remain in consumer products and the environment is of significant concern due to their potentially harmful effects. Effective screening is therefore imperative to prevent pesticides from entering the food chain or contaminating the environment.

This Seed Could Bring Clean Water to Millions
This Seed Could Bring Clean Water to Millions
News

Biomedical Engineering and Chemical Engineering Professors Bob Tilton and Todd Przybycien recently co-authored a paper with Ph.D. students Brittany Nordmark and Toni Bechtel, and alumnus John Riley, further refining a process that could soon help provide clean water to many in water-scarce regions. The process, created by Tilton’s former student and co-author Stephanie Velegol, uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium, termed “f-sand.”

Cryo-EM and CX-MS: The Power Couple of Proteomics
Cryo-EM and CX-MS: The Power Couple of Proteomics
Article

An ambitious new workflow has married two cutting-edge proteomic analysis techniques to improve imaging of large protein assemblies. The combination of electron cryo-microscopy (cryo-EM) and cross-linking coupled mass spectrometry (CX-MS) allows deeper interrogation of protein structures to a level of detail that the techniques are incapable of obtaining on their own.
