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! 🧵

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. Key findings in thread 🧵(1/9)👇

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

Antifaschismus, Widerstand, Verfolgung, NS-Täter & personelle / ideologische Kontinuitäten post 1945, Partisaninnenkunst. Bemerkenswert, was im Landesmuseum Kärnten / Koroška heuer sichtbar gemacht wird. Dort, wo Kärntner Slowenische Geschichte zuvor Jahrzehnte keinen Platz bekam.

Gleichzeitig ist vollkommen klar, dass das Ganze nichts mit Rassismus zu tun hat. Denn Spahn und Merz erwähnen nicht die Juden - anders als Goebbels am 20.8.1941 in seinen Tagebüchern: "Berlin muß eine judenreine Stadt werden (..) Sie verderben nicht nur das Straßenbild, son­dern auch die Stimmung."

Der aktuelle und bereits brüchige Waffenstillstand zwischen Israel und der Hamas darf weder für Israel noch für Deutschland zur Entlastung dienen. Er muss als Moment der Verantwortung verstanden werden: zur Aufarbeitung, zur Prävention und zur Durchsetzung des Rechts.

Foraging in conceptual spaces: hippocampal oscillatory dynamics underlying searching for concepts in memory www.biorxiv.org/content/10.1...

Functional connectivity (FC) is driven by 1/f. The approach: compute FC as usual, compute FC only with ROI where oscillations are 'present', then compare. Alpha lives, but not other bands. Idk, seems overstated. If beta comes in bursts: no peak, but could be FC doi.org/10.1523/JNEUROSCI.1041-25.2025

Italy should revoke its damaging migrant cooperation agreement with Libya, @hrw.org said today. The Italy-Libya Memorandum of Understanding on migration cooperation will renew automatically for three years on November 2, 2025, if neither party revokes it or makes any revisions by that date.
