New Portable Tool Analyzes Microbes in the Environment

Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.

Surprise discovery shakes up our understanding of gene expression

A group of University of Chicago scientists has uncovered a previously unknown way that our genes are made into reality. Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed—using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design.
