Why do some cancers respond to immunotherapy while others don’t? A new paper by @guimaguade.bsky.social shows, using maths, that as tumors mutate, they face a trade-off: growing faster can also make them easier for the immune system to spot. @sandyanderson.bsky.social www.biorxiv.org/content/10.1...

How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization?

We may have an answer: integration of learned priors through feedback. New paper with @kenmiller.bsky.social! 🧵

What can we learn about living computation from non-living machines? In this @royalsocietypublishing.org A. Adamatzky shows that a computer doesn’t need to be solid.

How can we design complex computational systems using synthetic biology? Check our paper, where we use space as a computational element, dramatically reducing communication requirements while allowing modularity, reusability, scalability & minimal cell engineering.

The 2025 #ClimateInequality Report brings together pioneering research conducted by @wid.world and universities worldwide and was edited by @lucaschancel.bsky.social & @cmohren.bsky.social with inputs from @pbothe.bsky.social @stellamuti.bsky.social

There is a strong positive association between equality and development over the long run — that's what this new study based on our historical series available on wid.world is clearly showing.

Germany’s new €377B military wish list A new procurement blueprint seen by POLITICO shows Germany’s plan to become the backbone of the continent’s defense revival.

www.politico.eu/article/germ...
Yes, Europe needs to do more to ensure its own defence and wean itself off US dependence. But for Germany to splurge hundreds of billions on military hardware is economic and political madness.

"from high-level heads of state to lower-level bureaucrats, as “co-perpetrators” alongside Libyan suspects for the death of 25,000 asylum seekers and abuses against some 150,000 survivors who were “abducted and forcibly transferred to Libya, where they were detained, tortured, raped, and enslaved.”"

Vorschieben, Frauen & Mädchen schützen zu wollen, als würde sexualisierte Gewalt vor allem von Migranten ausgehen, ist so hanebüchen wie perfide. Es ist rassistisch und misogyn zugleich - und eine klassische Erzählung von Rechtsextremen, die im Übrigen nicht auf "Schutz", sondern Besitzanspruch fußt
