From the website of the Nobel Prizes:
The Nobel Assembly at Karolinska Institutet has today decided to award the 2021 Nobel Prize in Physiology or Medicine jointly to David Julius and Ardem Patapoutian for their discoveries of receptors for temperature and touch.
Our ability to sense heat, cold and touch is essential for survival and underpins our interaction with the world around us. In our daily lives we take these sensations for granted, but how are nerve impulses initiated so that temperature and pressure can be perceived? This question has been solved by this year’s Nobel Prize laureates.

Postmortems on the war in Afghanistan stress errors of execution during the two decades of occupation. However, the greatest error may have been to invade at all.
Readers of Sebald increasingly agree that it is wrong to see the Jewish and German tragedy of the Holocaust as the sole focus of his work: the darkness of his vision extends much further, to the whole of human history, to nature itself. That is true. But here is my limitation: I am the daughter of Jewish refugees from Nazism. It was the fact that Sebald was the German writer who most deeply took on the burden of German responsibility for the Holocaust that first drew me to him, and it is still one of the things that most amaze and move me about his work. He didn’t want to be labeled a “Holocaust writer” and I don’t call him one here. But though the Holocaust was far from the only tragedy he perceived, it was his tragedy, as a German, the son of a father who had fought in Hitler’s army without question. It was also my tragedy, as the daughter of Viennese Jews who had barely escaped with their lives. I think it is right to see the Holocaust as central to his work. But if I make it too central, that is why.

Every person, every mouse, every dog, has one unmistakable sign of aging: hair loss. But why does that happen? Rui Yi, a professor of pathology at Northwestern University, set out to answer the question.
Social media have gutted institutions: journalism, education, and increasingly the halls of government too. When Marjorie Taylor Greene displays some dumb-as-hell anti-communist Scooby-Doo meme before congress, blown up on poster-board and held by some hapless staffer, and declares “This meme is very real”, she is channeling words far, far wiser than the mind that produced them. We’re all just sharing memes now, and those of us who hope to succeed out there in “reality”, in congress and classrooms and so on, momentarily removed from our screens and feeds, must learn how to keep the memes going even then. “Real-world” events, in other words, are staged by the victors in our society principally with an eye to the potential virality of their online uptake. And when virality is the desired outcome, clicks effected in support or in disgust are all the same. Thus the naive idea that AOC wore her “Tax the Rich” gown to a particular event attended by a select crowd within a well-defined physical space completely distorts the motivation behind the gesture, which was, obviously, to make waves not during, but immediately after, the event, not for the people at the event, but for all the people who were not invited.
Topologists study the properties of general versions of shapes, called manifolds. Their animating goal is to classify them. In that effort, there are a few key distinctions. What exactly are manifolds, and what notion of sameness do we have in mind when we compare them?
There is great emotional weight in literature. Anyone who has cried for the death of Old Yeller, laughed at the antics of Lucky Jim, or been thrilled by the adventures of Simon Templar can attest to that simple fact. What has never been simple is understanding why a string of written words can create such an emotional response, or possibly more important, why some strings achieve it so much more effectively than others.
I’m an audiovisual translator, which means that I—and others like me—help you understand the languages spoken on screen: You just click that little speech bubble icon in the bottom-right corner of your preferred streaming service, select the subtitles or the dub, and away you go. These scripts are all written by someone like myself, sitting quietly at a computer and spending day after day trying to figure out, “What are they actually saying here?”

On the cover of her new album, Dar Williams stands on a floating platform in a lake. A breeze ripples the water so that it’s as wrinkled as elephant skin. As Ms. Williams gazes toward an unseen horizon, her scarlet shawl flutters behind her like a vapor trail. The atomistic image is metaphorical. Ms. Williams says the photo, taken by a drone, makes her look like a red dot destination marker on a map. The album, debuting Oct. 1, is titled “I’ll Meet You Here.” “Somehow we have to figure out how to continue to meet the moment and meet one another,” even when we seem to be stranded, explains the folk singer in a phone call.
