  3. Vom einzelnen Fisch zum Schwarm

    Ein Fischschwarm kann sich beinahe wie ein einziger Organismus bewegen. Hunderte Tiere ändern gemeinsam die Richtung, ohne dass jemand vorgibt, wohin es gehen soll. Doch nach welchen Regeln entscheidet eigentlich der einzelne Fisch, wem er folgt?

    Forschende der University of California San Diego haben das an winzigen, nahezu durchsichtigen Fischen der Art Danionella cerebrum untersucht.

    Sie zeichneten die Bewegungen der Tiere in unterschiedlich großen Gruppen auf und entwickelten daraus ein mathematisches Modell. Dabei zeigte sich ein erstaunlich einfaches Prinzip.

    Ein Fisch orientiert sich offenbar nicht an der mittleren Bewegungsrichtung seiner gesamten Umgebung, sondern kopiert jeweils die Richtung eines einzelnen, zufällig ausgewählten Nachbarn.

    Entscheidend ist dabei auch das Timing. Wenn ein Fisch eine Kurve beendet, öffnet sich für seine Nachbarn ein kurzes Zeitfenster, in dem sie seine neue Richtung übernehmen können. Bei ausgewachsenen Tieren geschieht diese Reaktion besonders schnell. Viele solcher einzelnen, zeitlich abgestimmten Entscheidungen reichen dem Modell zufolge aus, damit auf Gruppenebene das typische Schwarmverhalten entsteht.

    Ob das Modell tatsächlich beschreibt, was die Tiere wahrnehmen und tun, testeten die Forschenden anschließend mit virtuellen Fischen. Echte Fische schwammen dafür in einer Virtual-Reality-Umgebung und bekamen künstliche Artgenossen präsentiert, deren Richtungswechsel gezielt gesteuert werden konnten. Die realen Fische reagierten dabei exakt so, wie es das Modell vorhergesagt hatte.

    Es ist spannend, wie aus einer so einfachen Regel ein komplexes Gruppenverhalten entstehen kann. Solche Prinzipien sind auch über die Biologie hinaus interessant, etwa für die Schwarmrobotik. Statt jeden Roboter zentral zu steuern, könnten dort einfache Regeln für die Interaktion mit den unmittelbaren Nachbarn dafür sorgen, dass sich eine ganze Gruppe koordiniert bewegt.

    Ob sich gerade diese gefundene Strategie dafür eignet, ist noch offen. Aber vielleicht können uns ausgerechnet winzige Fische etwas darüber beibringen, wie man große Gruppen ohne zentrale Steuerung organisiert.

  4. 💁🏻‍♀️ TIL: 🦾🏥 UC #SanDiego engineers achieved the first teleoperated #humanoid robot surgeries, successfully removing gallbladders in large #mammals.

    The 27 kg (60 lbs) #robots called Surgie needed recalibration multiple times and faced latency issues, but operators found the controls surprisingly natural. Researchers believe lower-cost, nimble humanoid robots could expand surgical access to rural areas and battlefields.

  12. Opinion | UC San Diego report: Incoming students are not ready for college – The Washington Post

    The signs of educational decline are now impossible to ignore

    UC San Diego report shows students are not prepared for college, especially in math.

    November 23, 2025, 5 min

    Some years ago, during a dinner party, our smoke detector started beeping while we were broiling steaks. I dashed into the hallway and poked at the detector with a broom, which paused, as if surprised, then resumed wailing. My husband came out of the kitchen and had a go. His more muscular attention bought us perhaps 30 seconds of relief, but the machine recovered and more aggressively assaulted our ears. Eventually we pulled the cursed thing out of its frame and ripped the batteries out.

    That’s when one of our guests said, “Guys, that’s really a lot of smoke.” It sure was, because as it turned out, our bathroom was on fire (thanks to a candle).

    Life is full of these messy signals. Prices are a signal. They tell us how much people want stuff, how much that stuff costs to produce and how much of it we have available. Standardized test scores are signs, telling us whether kids have mastered certain skills. Those warnings are, like my smoke alarm, highly imperfect. (We’ve had many alerts and exactly one fire.) But they contain vital information, and we ignore them at our peril.

    Unfortunately, because these signals are messy, we are often tempted to ignore them, especially when the information they contain is bad news, like “your bathroom is on fire,” or “your schools are failing to close persistent racial and income gaps,” or “regulations have made it too hard to build new housing.” Ideally you’d extinguish the fire or fix your failing schools or amend the regulations before the problem worsens. But solving problems is hard, and in politics, it often involves taking on well-organized constituencies that will wave away the smoke and insist that everything is just fine. So institutions often choose to disregard the underlying issues and simply whack the alarm with a hammer until it stops beeping.

    There has been a lot of that going on recently, most notably in education. Instead of rectifying disparities in preparation and achievement, people decided it would be simpler to adjust the measurements. Parents opposed standardized testing, got their kids disability diagnoses that allowed them extra time on tests and lobbied teachers to change bad grades. Exhausted teachers responded with grade inflation, which also helped conceal that low-income and minority kids weren’t doing as well as their richer and White peers. Progressive educators watered down curriculums, gutted gifted and talented programs, and weakened admissions standards for honors classes and magnet schools. Colleges dropped standardized testing requirements, in part because that made it easier to diversify their student body. None of these things happened everywhere, but they happened in many places, and all of them made it harder to see — or rectify — pandemic-era learning loss.

  13. **UC San Diego Review of Senate-Administration Workgroup Report on Admissions**

    "_Between 2020 and 2025, the number of students whose math skills fall below high school level increased nearly thirtyfold; moreover, 70% of those students fall below middle school levels, reaching roughly one in twelve members of the entering cohort._"

  17. Nowe badania Apple: roboty uczą się działać, oglądając świat oczami ludzi

    Apple, we współpracy z MIT, Carnegie Mellon i innymi uczelniami, zaprezentowało nowy sposób trenowania humanoidalnych robotów.

    W projekcie „Humanoid Policy ∼ Human Policy” roboty uczą się, analizując nagrania z perspektywy pierwszej osoby, zebrane za pomocą Apple Vision Pro.

    Naukowcy stworzyli zbiór danych PH2D, zawierający ponad 25 tys. ludzkich i 1,5 tys. robotycznych demonstracji manipulacji obiektami. Dzięki temu udało się wytrenować jeden, uniwersalny model AI, który może sterować humanoidalnym robotem w rzeczywistym świecie.

    Zamiast kosztownych i czasochłonnych sesji teleoperacyjnych, dane zebrano z pomocą aplikacji na Apple Vision Pro, wykorzystującej kamerę i technologię ARKit do śledzenia ruchu głowy i dłoni. Dla tańszej alternatywy badacze zaprojektowali też uchwyt na kamerę ZED Mini, kompatybilny np. z Meta Quest 3.

    Dodatkowo, by dopasować tempo ruchów ludzi do możliwości robotów, nagrania spowolniono czterokrotnie na etapie trenowania.

    Apple stworzyło urokliwą lampę-robota!

    Sercem projektu jest HAT – model AI, który uczy się na podstawie wspólnego formatu danych od ludzi i robotów. Zamiast oddzielnie analizować każdy typ źródła, HAT tworzy jedną uniwersalną „politykę działania”, co pozwala robotom lepiej radzić sobie z nowymi zadaniami.

    Badanie otwiera nowe możliwości w dziedzinie robotyki i pokazuje potencjał integracji technologii Apple w automatyzacji przyszłości. Więcej szczegółów tutaj.

    Więcej na temat robotów — nie tylko tych humanoidalnych, ale i przemysłowych — także w kontekście AI, usłyszysz w nowym odcinku mojego podcastu „Bo czemu nie?”.

    Disgusting news out of the University of California union fight...What do you think the chances are these folks have had their private digital devices and email combed through?

    Its almost a certainly. For what should be protected first amendment activity.

    When we talk about a right to privacy and making tools to protect those rights. This is the abuse we are talking about.
