AI-designed serotonin sensor may help scientists study sleep and mental health

Researchers have described how they used advanced genetic engineering techniques to transform a bacterial protein into a new research tool that may help monitor serotonin transmission with greater fidelity than current methods. Preclinical experiments, primarily in mice, showed that the sensor could detect subtle, real-time changes in brain serotonin levels during sleep, fear, and social […]

Genetic engineering without unwanted side effects helps fight parasites

Modified CRISPR-Cas9 gene editing scissors are enabling researchers to make alterations to the genetic material of single-cell organisms that are indistinguishable from natural mutations. This method is making it possible to develop a (harmless) experimental live vaccine for the widespread parasite Toxoplasma gondii.

Model predicts where ticks, Lyme disease will appear next in Midwest states

By drawing from decades of studies, scientists created a timeline marking the arrival of black-legged ticks, also known as deer ticks, in hundreds of counties across 10 Midwestern states. They used these data – along with an analysis of county-level landscape features associated with the spread of ticks – to build a model that can […]
