Targeting redundant gene families: A multiplexed, tissue-specific CRISPR toolbox for Arabidopsis genetic screens Anfang et al. present a tissue-specific, multiplexed CRISPR toolbox for plants that uses paired sgRNAs and barcoded libraries to target redundant gene families. Applied to Arabidopsis nutrient transporters, it boosts editing efficiency and gene coverage, enabling spatially precise screens that uncover phenotypes hidden by functional redundancy.

(1/3) My undergraduate student, Joh, is working on chromatin (magenta dots in the movie) dynamics during the altered nuclear (green) shape.

Here is a beautiful movie of chromatin dynamics.

Interbreeding between Neanderthals and modern humans was strongly sex biased Sex biases in admixture and other demographic processes are recurrent features throughout human evolution. For admixture between Neanderthals and anatomically modern humans (AMHs), sex bias has been p...

When Neanderthals and ancient modern humans interbred, the pairings were mostly between male Neanderthals and female humans, according to a new Science study.

This finding helps explain why Neanderthal ancestry present in most humans is unevenly distributed. https://scim.ag/4cQYpIL
