In a new paper published in the journal Nature, Michigan State University researchers Robert Quinn and Doug Guzior report the discovery of the enzyme responsible for producing microbially conjugated bile acids, some of the most abundant and crucial molecules in our gut.
People who experienced a disaster had a higher prevalence of problem alcohol use in the years after the disaster, and the rates of problem alcohol use increased over time. A study of nuclear power plant workers who experienced a disaster found that those who were exposed to life-threatening danger, discrimination, death of a colleague, or major property loss had an increased prevalence of problem alcohol use. However, for some, the increase in problem drinking did not occur until more than a year after the disaster. The study’s findings, recently published in Alcohol: Clinical and Experimental Research, point to the prolonged impacts on people who experience disaster and the importance of providing long-term monitoring and support beyond the immediate aftermath of the disaster.

The idea that people make decisions based on social context is not a new one in neural economic games. But now, for the first time, researchers publishing in Nature Human Behavior show the impact of the social context may spring from the dynamic interactions of dopamine and serotonin. Researchers built carbon-fiber electrodes that were implanted in patients receiving Deep Brain Stimulation surgery. The method allows researchers to measure more than one neurotransmitter at a time, revealing a dance that has never been seen before
Physicists from the National University of Singapore (NUS) have developed a novel method of repurposing fish scale waste to act as a bio-adsorbant to effectively remove the pollutant Rhodamine B from water, and a material for information encryption.
People who tend to act rashly when upset may be more likely to expect alcohol to affect them—both positively and negatively—and may be more likely to want to drink to improve their mood. Mood changes, whether positive, negative, or neutral, did not alter these beliefs, according to a study of college students published in a recent issue of Alcohol: Clinical and Experimental Research. This study helps to inform further research on the relationship between impulsivity and alcohol misuse.

Warmer soils harbour a greater diversity of active microbes, according to a new study from researchers at the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna. The study, published in Science Advances, represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate. Until now, scientists have assumed that higher soil temperatures accelerate the growth of microbes, thus increasing the release of carbon into the atmosphere. However, this increased release of carbon is actually caused by the activation of previously dormant bacteria.
Machines still can’t think, but now they can validate your feelings, based on new research from New Jersey Institute of Technology Assistant Professor Jorge Fresneda.

The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers at the University of Bristol and the Open University suggest.
It has been long assumed that Utah’s Bonneville Salt Flats was formed as its ancient namesake lake dried up 13,000 years ago. But new research from the University of Utah has gutted that narrative, determining these crusts did not form until several thousand years after Lake Bonneville disappeared, which could have important implications for managing this feature that has been shrinking for decades to the dismay of the racing community and others who revere the saline pan 100 miles west of Salt Lake City. Relying on radiocarbon analysis of pollen found in salt cores, the study concludes the salt began accumulating between 5,400 and 3,500 years ago, demonstrating how this geological feature is not a permanent fixture on the landscape.
