Jennifer Zieba in The Scientist:
Nerve cells, or neurons, are the basic functional units of the nervous system. Multiple interconnected neurons form a neural circuit and use electrical and chemical signals to quickly transmit information throughout an organism. The nervous system is broadly divided into two sections: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord whereas the PNS includes neurons that branch off from the CNS and connect to the rest of the body. In general, neurons in the PNS receive and carry signals in the body while neurons in the CNS analyze information.
…Typically, neurons share information by producing electrical events called action potentials, also known as nerve impulses, which involve rapid changes in voltage across their membrane. When a neuron’s dendrite or cell body receives enough inputs from other neurons via chemical or electrical synapses and a particular threshold for that neuron is exceeded, the neuron is triggered to send an action potential across its axon.

We wondered: Were we condensing phrases to terms because we were typing with our thumbs? Had we come to expect listeners and readers to autocomplete and fill in syntax? Had work jargon saturated private life because Americans worked such long hours? Had a generation told by daycare providers that they were good toy-picker-uppers grown up to make a norm of behaviorist verbing? Had the passive constructions by which one avoids assigning blame (or credit) in the workplace made naming who did what seem rude?
Fortunately, a whole raft of new technologies is being developed that make a system-wide revolution in food production feasible. According to recent research by one of us (Chris), this transformation could meet increased global food demands by a growing human population on
So, unfortunately, it’s time for another one of these. By which I mean both a “

OK, I’m going to do my best here. But I need you to know exactly what you are getting, as Joan Didion once wrote, and what you are getting is a man who cannot feel his face. My hands are still shaking. There are tears in my eyes. I’m writing this less than 10 minutes after the end of the greatest World Cup final ever, which Lionel Messi’s Argentina won on penalties over Kylian Mbappé’s France, and I do not believe it is recency bias that makes me think that this match was the single most thrilling sporting event I have ever witnessed. Every game is a story. And when you consider the stakes, the performances, the history in the balance, the refusal of either side to lose, the moments of astonishing play, the sudden reversals and wild swings of momentum, the knife’s-edge uncertainty of the outcome, and the epochal significance of a result that brought the career of the world’s best player to an almost magically perfect climax, it is hard to imagine a story more overwhelming or more satisfying than this one.
Rochelle “Shelley” Buffenstein has one of the world’s largest, if not the largest, lab-dwelling colonies of the naked mole rat. (No one has done a worldwide tabulation, but she has 4,500 of them.) Buffenstein has spent decades studying the little subterranean-dwelling rodents. Over the years, she and her colleagues have uncovered one surprising discovery after another, which has led them to re-orient the whole field of anti-aging research.
Leibovich: The Republican Party is in a strange place. The 2022-midterm losses stunned the GOP and created calls for a 2024 challenger to Donald Trump. But can the party move past the man who dominated it for six years? Now we’re actually going on seven years, almost eight years, right? It just keeps going and going. So, hi, Elaina—tell us everything.
The four designated stages inside the crowded stadium complex in the heart of the busy capital weren’t enough. So the poetry lovers also took to the footpaths and the spaces in between, turning them into impromptu open-mic platforms for India’s embattled language of love.
On the evening of December 2, 2020, around 10pm, I swallowed the last of what must have been multiple lifetimes’ worth of mouthsful of red wine. Unlike the partisans of AA, I am confident in saying that I will never again in my life consume alcohol. There are things I just don’t do anymore. I am no less morally certain, for example, that I will never go sky-diving. The version of me that believed a good life is constituted from such “fun” diversions as this died a long time ago. Far from having a “bucket list”, I now understand that the proper conduct of the second half of life is to approach something like what the Tibetan Buddhists call tukdam, to do less and less, but only to sit and meditate, and to breathe once every century or so, so that by the time you actually die there will be scarcely any change to register. I can picture a future not so far from now when, to the question, “Is he alive or dead?”, the only fitting response will be: “Who can say?” You might be able to jolt me into some new movement, like a fly removed from its long sleep in a jar of talc that flicks its wing in reluctant palingenesis (the phenomenon of being “born again”, which by the law of nomen est omen has long tricked me into thinking that Sarah Palin must be destined for a comeback); then again you might not. So, yeah, sky-diving’s out, along with drinking. The version of me that drank died two years ago. We’re coming up on the two-year anniversary of his death.
A grammatical problem which has perplexed scholars since the 5th century BC has been solved by a
