Out today in Nature: sex without crossovers. Rhynchospora tenuis makes pollen, fertilises and sets seed, yet 0 crossovers in 10,997 pollen nuclei. Chromosome drive and ~87% seed abortion rebuild the mother's genotype, so the offspring are clones. doi.org/10.1038/s415...

Wow! Only Good Antibodies has developed a new tool that lets you see, directly in a paper, which antibodies were tested and validated. A tool that comes at the right time, given all the issues surrounding antibody validation. Definitively a tool to get onlygoodantibodies.co.uk/extension/

Browser Extension — Only Good Antibodies
A free browser extension that marks antibodies cited in a paper with their knockout-controlled validation status, for the application they were used in.

How do transcription factors bind DNA strongly, and in a switch like manner, while remaining sequence specific? Our new paper on a canonical plant TF suggests the answer is a previously underappreciated assembly state: transcription factor nanoclusters. www.science.org/doi/10.1126/...
