Chatting with a brain scan --quite interesting work from Tim Kietzmann's lab:
We managed to integrate brain scans into LLMs for interactive brain reading and more.. check out Vicky's post below. Super excited about this one!
Introducing CorText: a framework that fuses brain data directly into a large language model, allowing for interactive neural readout using natural language.
tl;dr: you can now chat with a brain scan 🧠💬

Europe's MSCA postdoctoral fellowships are now attracting many researchers who would have gone to the US. So the payline has dropped below 10% (~1,600 fellowships to 17k applicants). Super tough situation. One more reason to double the next Horizon budget, as proposed by the EU Commission.
Applications for MCSA are up 64%! 50% now come from outside the EU. Trump effect?
The European Research market just got a hell of a lot more crowded.
EU should turn on the tap
