Preprint 🧵! I’m really excited to introduce BIGSMALL, an interleaved multi-magnification cryo-ET scheme bridging molecular and cellular scales in a single acquisition! BIGSMALL = 𝐁road 𝐈nformation 𝐆athering 𝐒trategy by 𝐌ultiscale 𝐀cquisition of lame𝐋𝐋a www.biorxiv.org/content/10.6... (1/6)

Happy to see the preprint of our VULCROM setup online! Thanks to our amazing collaborators we've managed to get some pretty cool cryo-CLEM images by combining cryo super-resolution and cryo-ET: doi.org/10.64898/202...

Big news for correlative cryogenic SMLM/ET! With my colleague Soheil, we (Mahamid and @jonasries.bsky.social labs) indicate lamella-specific illumination can allow 500-1500x higher laser intensities, opening massive new possibilities for correlative imaging #teamtomo www.biorxiv.org/content/10.6...

First steps into cryo-lamella imaging by cryo-secondary ion mass spectrometry using helium and neon ion microscopy! We look forward to continuing with correlative cryo-EM-SIMS. Great work: Antje Biesemeier and colleagues - Luxembourg Institute of Science and Technology. pubs.acs.org/doi/10.1021/...

Excited to advertise a fully funded PhD with @socialinfluenza.bsky.social investigating how influenza virus evolution differs between different avian hosts (and how this impacts pandemic potential). Joint between @pirbrightinst.bsky.social + @cvrinfo.bsky.social www.findaphd.com/phds/project...

Congratulations to Dao Thi lab @daothilab.bsky.social and collaborators! Beautiful work! @ciid-heidelberg.bsky.social

Meet our new #AllianceFellow Jack Whitehead! The short interview about his work in the @chlandalab.bsky.social and Mahamid lab at @embl.org can be found on our LinkedIn account. @jackwh18.bsky.social

We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it. A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !

Our latest preprint is now available doi.org/10.1101/2025...! Led by my postdoc, Luqiang Guo @luqiang.bsky.social, we determined a ~2.4 A resolution structure of the hantavirus glycoprotein tetramer on the surface of VLPs. Also determined structures of dimers of tetramers and Fab-bound tetramers.

Afterwards a panel discussion was moderated by Caroline Schlaufer featuring film director Christian Frei, biosafety expert Kathrin Summermatter & virologist @profvolkerthiel.bsky.social. The audience posed great questions on funding, biosafety & media polarisation.

📢Job alert📢 @uniheidelberg.bsky.social has an opening for a full W3-position on “Modeling of Biological Processes” 😀👍 Here is the call tinyurl.com/3w9e9dtf and application deadline is March 15. The group would be located at the beautiful #BioQuant center right in the middle of Neuenheimer Feld.

Cryo-EM structure reveals how influenza A virus NEP binds the viral polymerase at a regulatory hotspot, coordinating RNA synthesis and nuclear export. Fantastic collaboration with @loiccarrique.bsky.social and Jon Grimes. www.science.org/doi/10.1126/...

I am super happy to share this paper in its final form. We used FIB milling to "dig in to" cell lines and mouse brains infected with tick-borne flaviviruses, followed by cryo-ET to study the virus replication. It's open access, so have a look! #virology #teamtomo www.nature.com/articles/s41...

Spillover of #influenza A viruses from animals to humans represents a threat to our health. In this Perspective, Silke Stertz @virology.uzh.ch discusses emerging research that suggests some influenza A viruses can enter host cells via MHC-II receptors across species 🧪 #virology plos.io/4pP3Gnq

Our new preprint is out 🥳🥳🥳 Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence? 👇
