From Phys.Org:
Brain organoids—three-dimensional balls of brain-like tissue grown in the lab, often from human stem cells—have been touted for their potential to let scientists study the formation of the brain’s complex circuitry in controlled laboratory conditions. The discussion surrounding brain organoids has been effusive, with some scientists suggesting they will make it possible to rapidly develop treatments for devastating brain diseases and others warning that organoids may soon attain some form of consciousness. But a new UC San Francisco study offers a more restrained perspective, by showing that widely used organoid models fail to replicate even basic features of brain development and organization, much less the complex circuitry needed to model complex brain diseases or normal cognition.
“Some people have branded organoids as ‘brains in a dish’ but our data suggest this is a huge exaggeration at this point,” said Arnold Kriegstein, MD, Ph.D., a professor of neurology in the UCSF Weill Institute for Neurosciences, John G. Bowes Distinguished Professor in Stem Cell and Tissue Biology, and director of the UCSF Eli and Edythe Broad Center for Regeneration Medicine and Stem Cell Research, whose lab has been a leader in the development of cerebral organoid models (see prior studies here, here and here.) “We find that organoids do not develop the distinctive cell subtypes or regional circuit organization that characterize normal human brain circuits. Since most human brain diseases are highly specific to particular cell types and circuits in the brain, this presents a grave challenge to efforts to use organoids to accurately model these complex conditions.”

“There is an estate in the realm more powerful than either your Lordship or the other House of Parliament,” one Lord Campbell proclaimed to the peers in the House of Lords, in 1851, “and that [is] the country solicitors.” It was the lawyers, in other words, who kept England’s landed elite so very, well, elite: who shielded and extended the wealth of the landowners, even granting them legal protection against their own creditors. How did they pull off this trick? Through a nimble tangle of contracts, carefully and complicatedly applied, as Katharina Pistor explains in her lucid new book, The Code of Capital: by mixing “modern notions of individual property rights with feudalist restrictions on alienability”; by employing trusts “to protect family estates, but then [turning] around and [using] the trust again to set aside assets for creditors so that they would roll over the debt of the life tenant one more time”; and by settling the rights to the estate among family members in line for inheritance. Solicitors maximized their clients’ profits and worth through strategic applications of the central institutions at their disposal: “contract, property, collateral, trust, corporate, and bankruptcy law,” what Pistor calls an “empire of law.”

Cosmologists don’t enter their profession to tackle the easy questions, but there is one paradox that has reached staggering proportions.
The artist Jack Whitten, who died in 2018, approached his practice with the curiosity of a scientist and the playfulness of a jazz musician. Many of his paintings are the result of a careful aesthetic hypothesis unleashed upon the canvas and then transformed by improvisation. The works at the center of “

The dossier on cancer researcher Xifeng Wu was thick with intrigue, if hardly the stuff of a spy thriller. It contained findings that she’d improperly shared confidential information and accepted a half-dozen advisory roles at medical institutions in China. She might have weathered those allegations, but for a larger aspersion that was far more problematic: She was branded an oncological double agent. In recent decades, cancer research has become increasingly globalized, with scientists around the world pooling data and ideas to jointly study a disease that kills almost 10 million people a year. International collaborations are an intrinsic part of the U.S. National Cancer Institute’s Moonshot program, the government’s $1 billion blitz to double the pace of treatment discoveries by 2022. One of the program’s tag lines: “Cancer knows no borders.”

People have always disagreed about politics, passionately and sometimes even violently. But in certain historical moments these disagreements were distributed without strong correlations, so that any one political party would contain a variety of views. In a representative democracy, that kind of distribution makes it easier to accomplish things. In contrast, today we see strong political polarization: members of any one party tend to line up with each other on a range of issues, and correspondingly view the other party with deep distrust. Political commentator Ezra Klein has seen this shift in action, and has studied it carefully in his new book
Scientist and scholar Eric Toner, quoted above in an excerpt from a Friday interview with the business-news channel CNBC, explained that China’s efforts to contain the current outbreak of a fast-moving upper-respiratory illness are “unlikely to be effective.”
To those living in nations not yet consumed by fire, flood, or frost, we can report that for the most part, life seems to go on pretty much as it always has. There are some slight adjustments to be made. The morning routine now begins by checking the news to see which of the hundred or so fires raging out of control across the coast have joined forces to become super-fires, and which of these super-fires have united to become mega-fires. Time between breakfast and the daily commute might well be put aside to send text messages to friends and relatives closest to the hundred or so blazes lately listed as “out of control,” or whose last known location is in danger of immolation. Keeping tabs on where the destruction is taking place is made easier by an app called “Fires Near Me” which sends you an alert when any major fires are moving into your preselected “Watch Zones.” It has become commonplace for social gatherings to end with someone glancing down at their phone and exclaiming “Oh dear, the fires are coming round my place, I better be off.”
Perhaps no figure better illustrates the style and stakes of the hatred of literature, as it has filtered from academia into contemporary literary culture, than the American author Ben Lerner. Lerner, recently described in the New York Times as “the most talented writer of his generation,” was known for advertising his suspicion of aesthetic experience even before he published a book called The Hatred of Poetry in 2016. “I had long worried that I was incapable of having a profound experience of art,” says Adam Gordon, the college-age narrator of Lerner’s 2011 debut novel Leaving the Atocha Station, upon encountering a man crying before a painting at a museum in Madrid, “and I had trouble believing that anyone had. … I was intensely suspicious of people who claimed a poem or painting or piece of music ‘changed their life.’”
In November 1942, the German composer Karl Amadeus Hartmann traveled to Vienna from his home in Munich to spend an intense week of study with Anton Webern. The 37-year-old Hartmann was hardly a novice, but the opportunity to work with one of the masters of Viennese modernism (and a highly sought after pedagogue, at that) was too good to let pass. Hartmann could not have imagined, however, prior to his journey, just what kind of an outcast Webern had become. The Nazis had branded him a degenerate and proscribed his music, his finances were a shambles, and he was finding it increasingly difficult to compose. Indeed, with the exception of a single piece, the luminous Cantata No. 2, which he had already begun but would not complete for another year, Webern had by that point completed everything that he ever would. Upon arriving at Webern’s apartment in the suburb of Maria Enzersdorf, Hartmann discovered, much to his surprise, that he happened to be the composer’s only pupil.
In 1651, Thomas Hobbes famously wrote that life in the state of nature – that is, our natural condition outside the authority of a political state – is ‘solitary, poore, nasty brutish, and short.’ Just over a century later, Jean-Jacques Rousseau countered that human nature is essentially good, and that we could have lived peaceful and happy lives well before the development of anything like the modern state. At first glance, then, Hobbes and Rousseau represent opposing poles in answer to one of the age-old questions of human nature: are we naturally good or evil? In fact, their actual positions are both more complicated and interesting than this stark dichotomy suggests. But why, if at all, should we even think about human nature in these terms, and what can returning to this philosophical debate tell us about how to evaluate the political world we inhabit today?
