Researchers Use Vitamins to Decode Complex Interactions in the Soil Microbiome
Department of Energy, Office of Science

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.

Breaking Research Could Help to Advance Care for Overdose Patients Who’ve Taken Xylazine
Association for Diagnostic and Laboratory Medicine (ADLM (formerly AACC))

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.

Bromoform Molecules Like to Rearrange Their Atoms
Department of Energy, Office of Science

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.
