about the $100K H1B fee, here's some interesting details: "If an employee is in the U.S., he or she will not be subject if (i) applying to extend or amend H-1B status, or (ii) applying to change from another visa category into H-1B status from within the U.S."

1/ One of the questions I get asked about my book is what new they'll discover about #epigenetics. I hope there will be a lot to learn, but maybe one of the most intriguing stories will be about the contribution of John Pugh. www.amazon.com/Epigenetics-...

Liquid-liquid phase separation of HP1? Not in our mouse fibroblasts… This paper by the Fabian Erdel group offers a fresh perspective on how this can be reconciled with seemingly conflicting reports: The phase separation propensity of HP1 decreases from yeast → fly → mouse. doi.org/10.1038/s414...

🧬DZIF researchers have discovered that #HIV does not randomly integrate into the genome: the virus follows R-loops as signposts, with the enzyme Aquarius enabling the process. These findings open new avenues for potentially curative treatments. @marinalusic.bsky.social @natmicrobiol.nature.com

Is euchromatin really “open”? Our new study @bioRxiv suggests otherwise. Using super-resolution imaging @shiori-iida.bsky.social‬ @masaashimazoe.bsky.social reveals: Euchromatin forms condensed domains in live cells.

Many proteins bind RNA, yet we still don’t know what RNAs most bind because methods map one RBP at a time. In @cp-cell.bsky.social, with the Jovanovic lab, we describe SPIDR – a method for mapping the RNA binding sites of dozens of RBPs in a single experiment. www.sciencedirect.com/science/arti...

SPIDR enables multiplexed mapping of RNA-protein interactions and uncovers a mechanism for selective translational suppression upon cell stress @cellcellpress.bsky.social @mitchguttman.bsky.social www.cell.com/cell/fulltex...

How do enhancer-gene contacts relate to transcription activation? In mouse embryonic stem cells, a combo of STED, oligoFISH & RNA FISH shows that 3% of Dppa3 alleles transcribe. For these, enhancers and promoters come closer (panel E). Stumberger ... Leonhardt & Harz www.biorxiv.org/content/10.1...

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪 www.richmondscientific.com/how-a-discov...
