A LEGO robot , made by undergraduate students at Arizona State University, pours sucrose gradients (a tube with dense liquid at the bottom, and less dense liquid at the top), which are used to separate, say, proteins from RNA by spinning them really fast in centrifuges. How do transcription factors couple up with the correct RNA molecule?

The researchers first compared the editing efficiency of different versions of IscB when coupled with 'ωRNA,' which guides the enzyme to the right spot on the DNA. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome. Read more in Nature Methods.

In the case of semaglutide, those cells are Saccharomyces cerevisiae— also known as Baker’s yeast — engineered to secrete a peptide precursor that is later purified, chemically modified, packaged into an injectable or tablet form, and then shipped around the world. Continuing this method may not scale.
In general, antigen tests have a high specificity, though are not as sensitive as molecular tests that amplify the target viral DNA or RNA sequence in order to generate a quantifiable signal to indicate the presence of the virus in a sample.

Countries supported by PEPFAR saw HIV cases drop by 52 percent in 2023 compared to 2010, outpacing the 39 percent global decline. Since zidovudine failed to interfere with DNA-to-DNA replication, Ostertag wondered if it could block RNA-to-DNA replication instead. Thanks to Gavi’s AMC, GlaxoSmithKline has provided over 1.2
