Researchers have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.

Advances in nanotechnology are enabling innovations in fields like medicine and electronics by manipulating matter at the atomic level. A key focus is DNA nanotechnology at the University at Albany’s RNA Institute, which uses DNA structures for applications such as drug delivery and medical diagnostics.

A group of civil engineering technology students who worked on a research project at the Southern Alberta Institute of Technology (SAIT) in Calgary has concluded adding a certain amount of graphene to concrete can make the material more impermeable to water and increase the strength of the mix.
