Ik zeg het maar zoals het is. Deze vrouw heeft geen flikker voor de lhbtiq gemeenschap gedaan. Integendeel. Transgender wet tegen gehouden, geen gezinshereniging voor lhbt vluchtelingen. Niets gedaan voor meerouder gezinnen en conversie therapie nog steeds toegestaan. Zij liegt, VVD Pride liegt.

Netanyahu nominating Trump for the Nobel Peace Prize would come across as parody on crack, if it wasn't utterly disgusting

🧼"Why does soap make bubbles?"
✍️ β€œWhy can I draw with coloured pencils?”
πŸ’₯"How does a chemical explosion work?"
These are some of the questions that I answered during the Klokhuis questions day held at NEMO Science Museum on Saturday. Such a pleasure to work with these super enthusiastic children!

Excited to see this beautiful cover art by @barthvanrossum.bsky.social, which clearly illustrates our new bioconjugation chemistry for precise antibody modification in @jacs.acspublications.org! A big thank you to all co-authors @fmp-berlin.de & Tubulis GmbH and @humboldt-foundation.de for funding!

Foto van mij met lichtpaarse hoodie. Ik hou een groot bord vast met de tekst β€œ7 mythen over psychose”. Daaronder blauwe tekstvakken met gele silhouetten. Die teksten zijn niet te lezen op de foto, daarom link in de tweet.

In aanloop naar het debat over verward en onbegrepen gedrag, merkte ik weer hoe snel mensen hun oordeel klaar hebben.

Daarom steun ik deze actie van kenniscentra en patiΓ«ntenverenigingen van harte.

It's sort of ironic that your Director of Studies would have your ass on a platter for something like this, but the editor of Nature....not so much

it takes a special kind of confidence to identify such a complex yet specific molecule from mere IR spectra.

The progressive flag flies between two European Union flags in front of the European Commission headquarters in Brussels. Behind them, a large purple banner on the Berlaymont building reads β€œUnited for our Future 2024–2029” with a circle of yellow stars forming the EU symbol.

Today, we remember the Second World War in the Netherlands. πŸ‡³πŸ‡±

I’m sharing the story of Emanuel Speijer, a Jewish entomologist deported to Nazi camps. Studying insects there helped him endure the horror, and his work helped fight diseases. He survived, and so did part of his collection. 🐝πŸ§ͺ
