New Salmonella test boosts food safety for humans and animals

ITHACA, N.Y. – A new test allows accurate, rapid testing for Salmonella bacteria, one of the leading causes of food-borne illness across all regions of the world. Salmonella can infect animals as well as people, with commonly reported cases of people falling sick after handling pets and livestock. Tests that used to take days now […]

Bringing bacteria’s defense into focus

ITHACA, N.Y. – By taking a series of near-atomic resolution snapshots, Cornell University and Harvard Medical School scientists have observed step-by-step how bacteria defend against foreign invaders such as bacteriophage, a virus that infects bacteria. The process they observed uses CRISPR (clustered regularly interspaced short palindromic repeats) sites, where the cell’s DNA can be snipped […]

Bacteria-coated nanofiber electrodes clean pollutants in wastewater

ITHACA, N.Y. – Cornell University materials scientists and bioelectrochemical engineers may have created an innovative, cost-competitive electrode material for cleaning pollutants in wastewater. The researchers created electro-spun carbon nanofiber electrodes and coated them with a conductive polymer, called PEDOT, to compete with carbon cloth electrodes available on the market. When the PEDOT coating is applied, […]

Bacteria Be Gone! New Technology Keeps Bacteria From Sticking to Surfaces

Just as the invention of nonstick pans was a boon for chefs, a new type of nanoscale surface that bacteria can’t stick to holds promise for applications in the food processing, medical and even shipping industries. The technology, developed collaboratively by researchers from Cornell University and Rensselaer Polytechnic Institute, uses an electrochemical process called anodization […]
