Like humans, bacteria and archaea can be attacked by viruses. These microorganisms have developed their own immune defense strategies against their pathogens.

AUSTIN, Texas — In a first for the genetic toolset known as CRISPR, a recently discovered protein has been found to act as a kind of multipurpose

Novel platform has potential to detect many disease-related biomarkers in just one test Most conventional molecular diagnostics usually detect only a single disease-related biomarker. Great examples are the PCR tests currently used to diagnose COVID-19 by detecting a specific sequence from SARS-CoV-2. Such so-called singleplex methods provide reliable results because they are "calibrated" to a single biomarker. However, determining whether a patient is infected with a new SARS-CoV-2 variant or a completely different pathogen requires probing for many different biomarkers at one time. Scientis...

 E-Mail Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast. "There are clear advantages to being able to engineer probiotics so that they produce the desired molecules right where they are needed," says Nathan Crook, corresponding author of the study and an assistant professor of chemical and biomolecular engineering at North Carolina State University. "You're not just deliveri...
