A consortium of group leaders from IMP, IMBA (Vienna BioCenter) and ISTA has been awarded an FWF Emerging Fields grant to study how germ cells safeguard and pass on genetic information across generations.

The Trojan Horse is real, and it’s microscopic! 🐴🦠 Our paper is out today in @cellcellpress.bsky.social! We discovered that deltaviruses physically hide INSIDE helper viruses to sneak into new cells. And to prove it, we had to image them from every angle. 🧵👇 www.sciencedirect.com/science/arti...
