On nous répète matin midi et soir qu'il faut aller chercher l'argent à l'Europe, sauf que..... #ESR 😭 sciencebusiness.net/news/horizon...

Klimaschutz egal: Bund streicht Umweltauflagen für Rechenzentren Man* kann einfach nur noch den Kopf gegen die Wand schlagen. Wir müssen die Verantwortlichen endlich zur Rechenschaft ziehen. Sie zerstören unsere Zukunft.

Above 30 °C, C3 plants become heat-stressed: photosynthesis drops while respiration rises—so they make less sugar but use more. To compensate, they break down proteins (proteolysis), which produces ammonium that can accumulate and become harmful. A problem for plant and human user. #climatecrisis

Interesting read: „What is called a paper today is really a strange Frankensteined-together patchwork of supplementary files that run longer than the manuscript, datasets deposited in repositories that other researchers rarely reuse, and code posted to GitHub without documentation.“

Excited to give a whole seminar series on the hot topic of “Emergent Life-Like Dynamics in Synthetic Active Matter” Many interesting ideas out there that I will discuss with the students. If you know of articles that I should include, comment. @unileipzig.bsky.social #activematter 🧪⚛️

If you are interested in what I have to say about academia and my take on it, give it a read. 👇 #academicsky

„It didn’t happen by accident. It’s the product of a deliberate and systematic assault on knowledge by some of the richest people on Earth. Preventing climate breakdown means protecting ourselves from the storm of lies.“ @georgemonbiot.bsky.social #denialism #epistemic

Harald Lesch hat zu 100% recht! "Technologieoffenheit ist häufig ein Ausdruck für technologische Ahnungslosigkeit" und "Die Wärmepumpe ist die beste Maschine, die die Physik anzubieten hat, da gibt es keine Alternative" Endlich rechnet mal jemand mit diesem Bullshit-Argument der Union ab.

Congrats to Kelly for her beautiful Janus image in that was among the first 3 in the scientific image contest cfaed.tu-dresden.de/media-commun...

Sad to hear that Jane Goodell, a pioneering primatologist, has died. She was one of the first to study primates in their natural habitat, live with them and truly trying to understand their connection to us humans. To me she has been a great source of inspiration. We truly lost a great person! 🧪

Great to see my interview on Optics&Photonics News got published now You can learn more about my own career choices, how I navigated academic and industrial environments and how a changing mindset opened up new opportunities for me. Thanks Rachel for sharing my story! @optica-opn.org #ECR 🧪💡

Very happy to see that our lab has reached the Gold 🥇 certification of #LEAF 🍃 for our efforts to become a more sustainable lab environment. @quidantsnsl.bsky.social #greenlabs #sustainability

Apparently under the US new rules our latest preprint wouldn’t be allowed given it talks about „barriers“ Nevermind that this is just an optofluidic one 😅

Every time you see what sounds like a wild claim about woke research, you can assume a) it will fall apart under the most basic of inspection, b) the person making the claim will never be held accountable for lying, and c) it is a cover to gut useful research that we benefit from.

What?! They are closing Skype in May. In my community we are still actively using it as it is less clunky than Teams and much more reliable. Will be missing it….

Bei der Bundestagswahl geht es um viel: nicht weniger als die Zukunftschancen unserer Kinder & Enkel. Die Welt ist in einem Wettlauf gegen die Zeit, eine katastrophale 3-Grad-Welt zu verhindern. Was auf dem Spiel steht hier nochmal kurz aus erster Forscherhand erklärt. ▶️ youtu.be/M6NWcKb5QBs?...

Happy to see my first book chapter being printed! #activecolloids There is something simply valuable when you actually hold it in your hand. #postdoclife

Have nissed this end of last year. Simplifying the admin load sounds like a truly progressive move forward.

Strong signal of ETH on current rollbacks in #DEI

Now almost 450 signatories to my open letter calling on the @royalsociety.org to stand up for its values & deal with the widespread concerns raised by Elon Musk's Fellowship. Please consider signing & sharing: forms.gle/miDciq35oxyw... List of signatories here: occamstypewriter.org/scurry/2025/...

Strange to see that large non-profit organizations which had DEI as one of their most valued programs and initiatives are shutting their websites on these issues down… IMO erasing and diminishing their effort over the last decades and the ppl who were standing behind this

Unbedingt anhören! www.deutschlandfunk.de/die-angst-de...

Who is going to attend #BiophotonicsCongress this year in San Diego? Hope to see you there! 👋 For all members of the technical group on Optical Trapping and Manipulation, stay tuned as we are planning some exciting events for you. @opticaltrapping.bsky.social @optica.bsky.social

Here, broken down into a thread, is a copy of my last post on X. 1. This is my farewell post. I am not deleting this account, as I don’t want to lose the archive, and I don’t want my name taken by imposters. But, for as long as Musk owns the platform, I’ll no longer use it.
