When the sidechain bases guanine (G) and uracil (U) are paired in the 3D structure of a molecule of ribonucleic acid (RNA) the unusual pairing creates an unusual molecular conformation called a “wobble," pictured on the left. New research shows that non-covalent modifications to the bases can further alter the conformation creating a “shifted wobble," shown on the right. This conformational diversity could help explain RNAs function versatility, according to the researchers. Credit: Md Sharear Saon/Bevilacqua Lab / Penn State. Creative Commons

Unusual molecular conformation could help explain RNA’s versatility
A group of tiny particles can be made to follow a different group of particles in new experiments demonstrating the first steps in creating intelligent communicating systems involving active particles — sometimes called nanobots — that perform specialized tasks. In the experiment particles coated with the enzyme acid phosphatase (AcP) moved toward a chemical gradient of glucose-6-phosphate (G6P), which it converts to glucose that attracts the particles coated with the enzyme glucose oxidase (GOx). The situation is akin to a predator chasing its prey or a police officer pursuing a criminal. Credit: Provided by the Sen Laboratory / Penn State. Creative Commons

A new method to measure RNA velocity — which describes rate of gene expression in a single cell — overcomes limitations of previous methods and can incorporate spatial information as well as data from cells processed at different times. The new method, called spVelo incorporates two types of neural networks: a Variational Autoencoder that models gene expression and a Graph Attention Network that allows the incorporation of spatial and batch information from the sequencing data.
