Trump USAID Cuts Killed One Million People 750,000 died in the first year. By 2030 defunding USAID will kill 9.4 Million people, and 2.5 Million Children under the age of 5. Trump’s most lethal policy will almost surely be his 71 percent cut in humanitarian aid. www.nytimes.com/2026/05/09/o...

I took a 10-year break from g-ratio imaging to focus on vendor-neutral MRI. In the meantime, Alexander Gow at the American Society for Neurochemistry (ASN) and @jackvanhorn8.bsky.social at the @ohbmofficial.bsky.social have been leading a g-ratio revival. 1/2
New paper out from our lab, together with Anat Perry! We asked if empathy is reduced when watching someone in pain in a pre-recorded video or live. Short answer: no, at least as far as our behavioral and electrophysiological measurements go. Check out the long answer in the paper: rdcu.be/fdEMr
Empathy for pain persists across live two-way video interactions and viewing of prerecorded videos

Harald Lesch bringt es auf den Punkt: Viele sind “geschockt, dass wir demonstrieren müssen für den gesunden Menschenverstand, für erneuerbare Energien.” Aber angesichts von Reiches fossiler Lobbypolitik müssen wir das tun - und das werden wir morgen bundesweit. Erneuerbare Energien verteidigen!
1/6 Our paper is out today in Nature Communications! From the SFB/TRR 289 Treatment Expectation @sfb-trr-289.bsky.social we show that temporal expectations shape somatosensory perception - for both painful heat AND non-painful cold stimuli.
The #ERC just announced new rules! erc.europa.eu/news-events/... If you got a B score before, you’re blocked for 2 years (instead of 1). A C score means 3-year exclusion. This applies to the 2027 call for now, but I’d expect this to stick. Important for anyone planning to apply this round!

How do priors influence speech processing? Do they enhance expected signals or highlight the unexpected (prediction errors)? @fabianschneider.bsky.social' s work shows: It depends!
Same sound, different perception: Do expectations change what you hear?👂🧠 We paired faces w topics and played the same ambiguous speech w different faces. The brain sharpened sensory signals toward predictions and showed gated prediction errors at higher levels. Read @plosbiology.org. Blueprint👇
