# brain: how the brain says 'Oops!'

AA << have uncovered how signals from a group of neurons in the brain's frontal lobe simultaneously give humans the flexibility to learn new tasks—and the focus to develop highly specific skills. >>

<< The study's key finding is that the brain uses the same group of neurons for performance feedback in many different situations—whether a person is attempting a new task for the first time or working to perfect a specific skill. >>

<< Part of the magic of the human brain is that it is so flexible, (..) We designed our study to decipher how the brain can generalize and specialize at the same time, both of which are critical for helping us pursue a goal. >> Ueli Rutishauser. ️

New Study Reveals How the Brain Says 'Oops!'. Cedars-Sinai Medical Center. May 5, 2022. 

AA << recorded the activity of more than 1000 neurons in the medial frontal cortex of human epilepsy patients while they performed complex cognitive tasks. They found that domain-general and domain-specific performance monitoring neurons were intermixed within this brain region. The population activity gave rise to a geometry that allowed domain-general signals to be read out with more than 90% accuracy on single trials while at the same time retaining the ability to separate different conflict conditions. These results show how the human medial frontal cortex resolves the fundamental trade-off between task generalization and specialization, which is critical for cognitive flexibility. >>

# acad: oops! published papers in top psychology, economics, and science journals that fail to replicate are cited more than those that replicate.

<< Papers in leading psychology, economic and science journals that fail to replicate and therefore are less likely to be true are often the most cited papers in academic research, >>

The study << explores the ongoing "replication crisis" in which researchers have discovered that many findings in the fields of social sciences and medicine don't hold up when other researchers try to repeat the experiments. The paper reveals that findings from studies that cannot be verified when the experiments are repeated have a bigger influence over time. The unreliable research tends to be cited as if the results were true long after the publication failed to replicate. >>

<< We also know that experts can predict well which papers will be replicated, (..) Given this prediction, we ask 'why are non-replicable papers accepted for publication in the first place?' >> Marta Serra-Garcia.

<< Their possible answer is that review teams of academic journals face a trade-off. When the results are more "interesting," they apply lower standards regarding their reproducibility. >>

<< Interesting or appealing findings are also covered more by media or shared on platforms like Twitter, generating a lot of attention, but that does not make them true, >> Uri Gneezy.️

PS:  io non sono mai stato testimone di alieni o di manifestazioni di entità aliene. Tuttavia, forse (qui sottolineo forse), potrei averne frequentata una per decenni. Mia madre era per me una incognita; beveva l'essenziale, non fumava, non dormiva, mangiava poco, non si ammalava, era sempre in energico movimento. Passati i novanta anni di età - grondante di sudore, dopo avere trascorso, giusto per passare il tempo, un paio di ore a stirare nel mezzogiorno della calura agostana riminese - qualche volta l'ho sentita pronunciare la frase: "andrò a coricarmi perchè mi sento un po' stanca". Quando lei entrava in una stanza io immaginavo che virus e batteri sarebbero fuggiti terrorizzati per cercare di evitare quello che di lì a poco sarebbe potuto succedere. Lei era impermeabile a qualsivoglia ideologia o argomentazione che non si traducesse in immediata modalità operativa. Quale (apparente) paradosso, per lei era anche normale individuare e ribaltare immediatamente i punti chiave in merito a qualsiasi argomento. Anche se non lo dava a vedere, era una persona sostanzialmente avversa a qualsivoglia autorità imposta. Ricordo bene che le uniche tesi che non aggrediva erano quelle che trattavano la musica blues, il jazz, il rock - forse perchè intuiva che tali approcci fossero per sè stessi fondamentalmente auto-ribaltanti - e la chimica che, anche quando poteva contenere aspetti meramente speculativi, fantasmatici, lei avrebbe potuto comunque scorgere qualche indispensabile componente operativa osservazionale- sperimentale. 

Per questa sua unicità, dall'età di dieci anni fino ai quindici, ho avuto il sospetto che lei potesse essere il prodotto di qualche ignoto esperimento alieno. 

A distanza di decenni penso che mia madre, sebbene da bambina le avessero imposto di conseguire la sola istruzione elementare - come peraltro molte della sua generazione, sarebbe stata (terrestre o aliena) un valido 'naturale' co-addestratore nel team di una scuola Shaolin.

# astro: oops? apropos of rapid expansion of trajectories, the nomadic escape propensity of Titan.

As a vision of a fuzzy snooker, << decades of measurements and calculations have revealed that Titan's orbit around Saturn is expanding- meaning, the moon is getting farther and farther away from the planet- at a rate about 100 times faster than expected. The research suggests that Titan was born much closer to Saturn and migrated out to its current distance of 1.2 million kilometers (about 746,000 miles) over 4.5 billion years. >>

<< Titan is expected to gravitationally squeeze Saturn with a particular frequency that makes the planet oscillate strongly, similarly to how swinging your legs on a swing with the right timing can drive you higher and higher. This process of tidal forcing is called resonance locking. Fuller (Jim Fuller) proposed that the high amplitude of Saturn's oscillation would dissipate a lot of energy, which in turn would cause Titan to migrate outward away from the planet at a faster rate than previously thought. >>

<< The resonance locking theory can apply to many astrophysical systems. I'm now doing some theoretical work to see if the same physics can happen in binary star systems, or exoplanet systems, >> Jim Fuller.

# life: oops! trust in (British) politics

<< In previous British elections, to say that trust was the main issue would have meant simply that trust is the trump card – whichever leader or party could secure most trust would win. Now, the emerging question about trust is whether it even matters anymore. >>

<< Even many Labour voters don’t rate their leader as trustworthy. Neil Hall/EPA >>

<< These are moral judgements of the utmost significance. So it suggests that British democracy is in some moral jeopardy, when the leaders of the two major parties, the only likely candidates for the premiership, were rated so low on trustworthiness by the public, including supporters of their own party. For example, according to one YouGov poll, 53% of respondents thought Johnson untrustworthy, while for Corbyn the figure was 57%. (..) These figures suggest not only seriously depleted trust but also a substantial readiness amongst voters to separate trustworthiness from electability.  (..) A lack of trustable people creates insecurity, and in this anxious environment some people will want to convince themselves, whatever the evidence, that they have found a trustworthy leader.  (..) On that front, the most significant outcome may not be the seats won by the competing parties, but the national profile as expressed in the popular vote, and what it tells us about whether trust matters. >>
