Yes, managed to roll in the station and get out with my kids before the flames really picked.. Thanks to a Shell lady who doused it quickly in extinguisher, there was no explosion, even if we filled the place with smoke and panic 😅

This paper combines two sort-of-crazy (in the best sense) approaches in cryoEM sample preparation:
(1) Native, soft-landing electrospray ion beam deposition, followed by (2) deposition of amorphous ice, and reheating and freezing by laser flash melting. Has potential for time-resolved studies.

NEW: Judge Burroughs GRANTS Harvard's requested TRO against the Trump administration, blocking it from revoking Harvard's ability to enroll international students during early court proceedings.

ORDER GRANTING PLAINTIFF'S
MOTION FOR A TEMPORARY RESTRAINING ORDER
For purposes of Federal Rule of Civil Procedure 65(b), the President and Fellows of
Harvard College ("Plaintiff") has made a sufficient showing that it has provided notice to
Defendants Department of Homeland Security, Kristi Noem, Immigration and Customs
Enforcement, Todd Lyons, Department of Justice, Pamela Bondi, Student and Exchange Visitor
Program, Jim Hicks, Department of State, and Marco Rubio (collectively, "Defendants") and that, unless its Motion for a Temporary Restraining Order ("TRO"), [ECF No. 4 (the "Motion")],
is granted, it will sustain immediate and irreparable injury before there is an opportunity to hear
from all parties. Thus, a TRO is justified to preserve the status quo pending a hearing and the Plaintiff's Motion is GRANTED.
Accordingly, Defendants, their agents, and anyone acting in concert or participation with
Defendants are hereby enjoined from:
A. Implementing,
instituting, maintaining, or giving effect to the revocation of
Plaintiff's SEVP certification;
B. Giving any force or effect to the Department of Homeland Security's May 22, 2025
Revocation Notice.

It is so ordered
May 23, 2025

Petya Krasteva's research explores the structure & behaviour of these biofilms, hoping to develop new #antimicrobial strategies.

Welcome to Bluesky and thank you for this post 🙏. Indeed it was a real rollercoaster and this grant came as a lifeboat in the cold and lifeless ocean of public research in France, where institutional support is a net negative 😄. So we'll rock on for another 5 years while ignoring admin emails 🤘🤘🤘

Happy to share our 📖 chapter on bacterial cellulose secretion! It took too long in press so it doesn't include our latest work on pEtN-cellulose secretion (doi.org/10.1038/s414...), which settled many open questions but nevertheless, hope you enjoy the read 🤓!
