New work from @stephentang23 et al. that describes a fascinating set of reverse transcriptases involved in antiviral immunity. They synthesize tandem-repeat cDNAs that resemble telomeres, revealing an unexpected bacterial evolutionary origin of telomerase. Check out the thread!

Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from? Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria. doi.org/10.1101/2025.1…

One of my favorite technologies, developed in recent years, is two-photon holographic optogenetics. It is a way to both stimulate and record activity from thousands of individual neurons in real-time; akin to playing the brain like a piano. Here is how it works: In classical…

How does hunger spur us to consume? @Columbia scientists have found a brain area that drives mice to consume sweets, fats, salt & food. This finding may inform novel treatments for both overeating and undereating. See @CellCellPress #neuroscience zuckermaninstitute.columbia.edu/brain-dial-con…
