Researchers from UC San Diego analyzed the latest data from one of the nation’s largest long-term studies of youth to better understand when substance use begins, how it changes during adolescence and which substances are most commonly used together.

Scientists use E. coli TGT as a primary model to understand how TGT works in other bacteria, but have struggled to visualize its atomic structure. UC San Diego biochemistry professor Neal Devaraj’s lab has captured the first cryo-EM visualizations of E. coli TGT structure.

Researchers at UC San Diego have developed a large-scale screening approach that identifies proteins controlling a fundamental step in gene expression known as alternative polyadenylation (APA). APA determines where an RNA molecule is cut and finished before it is translated into protein.

Using data from 1.5 million respondents in the Tobacco Use Supplement to the Current Population Survey, researchers created a “Willingness to Restrict Smoking” (WTRS) scale that captures how strongly people believe smoking should be restricted in public settings.

Early biological systems that could generate guanosine‑triphosphate (GTP) from prebiotic chemicals would gain a crucial advantage toward self‑replication. Now researchers from the UC San Diego report a version of an RNA enzyme (ribozyme) that makes GTP synthesis more efficient than its predecessor.
