Michele Solis in Scientific American:
What makes the human brain special? That question is not easy to answer—and will occupy neuroscientists for generations to come. But a few tentative responses can already be mustered. The organ is certainly bigger than expected for our body size. And it has its own specialized areas—one of which is devoted to processing language. In recent years, brain scans have started to show that the particular way neurons connect to one another is also part of the story. A key tool in these studies is magnetic resonance imaging (MRI)—in particular, a version known as diffusion tensor imaging. This technique can visualize the long fibers that extend out from neurons and link brain regions without having to remove a piece of skull. Like wires, these connections carry electrical information between neurons. And the aggregate of all these links, also known as a connectome, can provide clues about how the brain processes information.
A persistent question about connectomes has to do with what, if anything, distinctive wiring patterns have to do with the evident cognitive differences in a mouse, a monkey or a human. A new methodology called comparative connectomics has identified some general rules of brain wiring across species that may help provide answers. In the meantime, it has also found some unique facets of the human connectome and discovered changes in the cells charged with the upkeep of brain wiring. Together these evolutionary innovations seem to keep information flowing efficiently through a large human brain. And when they are disrupted, they may give rise to psychiatric disorders.

The 19th Amendment, ratified in August 1920, paved the way for American women to vote, but the educator and activist Mary McLeod Bethune knew the work had only just begun: The amendment alone would not guarantee political power to black women. Thanks to Bethune’s work that year to register and mobilize black voters in her hometown of Daytona, Florida, new black voters soon outnumbered new white voters in the city. But a reign of terror followed. That fall, the Ku Klux Klan marched on Bethune’s boarding school for black girls; two years later, ahead of the 1922 elections, the Klan paid another threatening visit, as over 100 robed figures carrying banners emblazoned with the words “white supremacy” marched on the school in retaliation against Bethune’s continued efforts to get black women to the polls. Informed of the incoming nightriders, Bethune took charge: “Get the students into the dormitory,” she told the teachers, “get them into bed, do not share what is happening right now.” The students safely tucked in, Bethune directed her faculty: “The Ku Klux Klan is marching on our campus, and they intend to burn some buildings.”

Identity politics has become a secular religion and, like any strict sect, apostates are severely punished.
Here’s a deceptively simple exercise: Come up with a random phone number. Seven digits in a sequence, chosen so that every digit is equally likely, and so that your choice of one digit doesn’t affect the next. Odds are, you can’t. (But don’t take my word for it:
Sadly, you know that your side is losing the war of ideas when they start handing propaganda victories to the side you despise on a platter. Three years ago, in the context of a Lee statue that was going to be taken down, after that terrible anti-Semitic Charlottesville rally by white supremacists, Trump made a loathsome remark about there being “fine people” on all sides and also asked a journalist that if it was Lee today, would it be Jefferson or Washington next? I of course dismissed Trump’s remark as racist and ignorant; he would not be able to recite the Declaration of Independence if it came wafting down at him in a MAGA hat. But now I am horrified that liberals are providing him with ample ammunition by validating his words. A protest in San Francisco toppled a statue of Ulysses S. Grant – literally the man who defeated the Confederacy and destroyed the first KKK – and
Barbara Ehrenreich was born in Butte, Montana, where her family had lived for generations, in 1941. Most of her male ancestors lost fingers working in nearby copper mines. But her father attended night school, then won a scholarship to Carnegie Mellon; the family moved to Pittsburgh and rose into the middle class. Ehrenreich studied physics in college, got a doctorate in cell biology, and, in the late sixties, alongside her husband at the time, John Ehrenreich, she became involved in health-care organizing and antiwar activism.
Initially, the street was named after a British doctor/spy named James Burnes. Although the name was changed to Muhammad Bin Qasim Road Post-Partition, it is still known as Burns Road or more affectionately, “Buns Road”. But the neighborhoods around Burns Road are considered to have housed the earliest settlements in the city of Karachi, dating back to 1857.
