In a pair of publications, researchers investigated how different species of microbes interact with one another and exchange resources such as vitamins. The studies focused on corrinoids, the vitamin B12 family of nutrients. Many bacteria in the environment cannot produce these chemicals. The studies demonstrated that the presence of corrinoids can influence how individual soil bacteria grow in the laboratory and how they survive and coexist in soil.

Through a partnership with a nearby university, the middle schoolers collected and analyzed environmental samples to find new antibiotic candidates. One unique sample, goose poop collected at a local park, had a bacterium that showed antibiotic activity and contained a novel compound that slowed the growth of human melanoma and ovarian cancer cells in lab tests.

A chemical reaction can convert two polluting greenhouse gases into valuable building blocks for cleaner fuels and feedstocks, but the high temperature required for the reaction also deactivates the catalyst. An Oak Ridge National Laboratory team has found a way to thwart deactivation.

A novel study published today in ADLM’s journal, Clinical Chemistry, has found that it takes the human body much longer than previously thought to clear xylazine — one of the most popular emerging drugs of abuse in the U.S. This much-needed insight into how the body processes xylazine could improve treatment of overdose patients who’ve taken it.

Building on previous work, researchers in ACS Infectious Diseases have demonstrated a potential antibacterial treatment from a modified darobactin, a compound originally from a bacterium. The team reports proof-of-concept animal trials on infections caused by bacteria, including E. coli, that are known to develop drug resistance.

For the first time, scientists can distinguish the proportion of bromoform molecules that directly break bonds (dissociate) vs. those that rearrange (isomerize). This is an important step toward understanding the formation of bromoform isomers, which had long been predicted but had not been fully experimentally confirmed.
