New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost

As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and ...

You leave a 'microbe fingerprint' on every piece of clothing you wear—and it could help forensic scientists solve crimes

When you think of a criminal investigation, you might picture detectives meticulously collecting and analyzing evidence found at the scene: weapons, biological fluids, footprints and fingerprints. However, this is just the ...

Germ-free animal models reveal gut bacteria's role in health

Once considered a minor component of the digestive system, the gut microbiota has now been recognized as a critical player in overall human health. This revelation was first highlighted by scientist Elie Metchnikov in the ...

Study sheds light on how antibiotic 'Velcro' kills bacteria

A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface, similar to how both sides of Velcro ...

A merger of microbes: Study shows low-nutrient conditions alter viral infection

This much we know: When viruses infect bacteria—a common occurrence in oceans, soils, even human guts—the interaction results in the creation of entirely new organisms called "virocells." But scientists are still learning ...

Uncovering new details on antibiotic resistance from 1940s milk samples

Sometime in the 1940s or so, someone in what is now the Department of Pathobiology and Veterinary Science got a lyophilizer, a piece of equipment that freeze-dries samples, says Director of the Connecticut Veterinary Medical ...

Farm wastewater modeling shows footbaths are source of antimicrobial resistance

New research has mapped wastewater flows on farms and revealed where spikes in antibiotic resistant bacteria in slurry occur, showing that water from copper and zinc footbaths used by dairy animals can cause fluctuations.
