Markman Ellis in the Los Angeles Review of Books:
What does coffee do to you? Dinah Lenney’s Coffee is a free-form exploration of such surprisingly complicated questions: Why do we drink coffee? What gives it its power? Humans have been considering these and other coffee-related queries (like “Is it good for my health?” and “Is it good for my society?”) for centuries, ever since they first encountered the substance. Lenney is most interested in coffee’s direct effects on our lived experience, and what they mean.
The active property of coffee is called caffeine, as we all know. The word for the compound was coined in 1830, as a result of research by two different groups of scientists — one in Jena, Germany, led by a young chemist Ferdinand Runge, and the other in France, led by Pierre Jean Robiquet and Pierre Joseph Pelletier. Both groups successfully isolated the active substance of coffee in an organic “base” or vegetable salt. They showed that this salt caused the effects associated with coffee in humans. Caffeine, in other words, is the drug, and coffee is its vehicle. In 1861, Adolph Strecker defined the molecular structure of caffeine in the formula C8H10N4O2. Caffeine isn’t everything, though: coffee still tastes reasonably like coffee without caffeine, and coffee’s distinctive flavors, we now think, reside in a different set of chemical substances, including aromatic oils and volatile flavonoids, most of which are produced during the pyrolytic roasting process.

I recall an illuminating moment a decade or so ago. Cathy Guisewite had just announced she would step back from creating new instalments of her long-running
ON MY DOORMAT,
When I was a teenager I was, like most teenagers, preoccupied with the idea that somewhere on the horizon there was a Now. The present moment came to a peak out there; it achieved a continuous apotheosis of nowness, a wave endlessly breaking on an invisible shore. I wasn’t quite sure what specific form this climax took, but it had to involve some concatenation of records, poems, pictures, parties, and behavior. Out there all of those items would be somehow made manifest: the pictures walking along in the middle of the street, the right song broadcast in the air every minute, the parties behaving like the poems and vice versa. Since it was 1967 when I became a teenager, I suspected that the Now would stir together rock ’n’ roll bands and mod girls and cigarettes and bearded poets and sunglasses and Italian movie stars and pointy shoes and spies. But there had to be much more than that, things I could barely guess. The present would be occurring in New York and Paris and London and California while I lay in my narrow bed in New Jersey, which was a swamplike clot of the dead recent past.
The smart play for Trump is to postpone the nomination to reduce the risk of Democratic mobilization, and to warn Republicans of the risks should he lose. Trump’s people do not usually execute the smart play. They are often the victims of the hyper-ideological media they consume, which deceive them about what actually is the smart play. This time, though, they may just be desperate enough to break long-standing pattern and try something different.
Over the course of two decades spent developing treatments for the genetic lung disease cystic fibrosis, biologist Fredrick Van Goor has had hundreds of conversations with patients. But he remembers one in particular. The discussion was about the genetics of cystic fibrosis, a disease that develops when a person inherits two faulty copies of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This gene encodes the CFTR protein, which resides in the cell membrane and transports chloride and bicarbonate ions out of the cell. More than 2,000 variants of CFTR have been identified, and more than 350 of them are known to produce enough disruption in the protein’s function to trigger the debilitating and life-shortening condition. The focus of the conversation was the inevitable inequities of personalized medicine, which can be highly effective for people who meet certain criteria, but will leave others behind — as was the case for this patient. “He described it as being on a sinking ship, when all of the other lifeboats have left,” Van Goor recalls. “That image has stuck with me.”
There are as many as 9 million feral swine across the U.S., their populations having expanded from about 17 states to 38 over the last three decades. Canada doesn’t have comparable data, but Ryan Brook, a University of Saskatchewan biologist who researches wild pigs, predicts that they will occupy 386,000 square miles across the country by the end of 2020, and they’re currently expanding at about 35,000 square miles a year.
For good reason, The Great Gatsby is one of the most admired and talked-about books of the twentieth century. And that reason is, of course, that it’s really short—47,094 words, to be exact. I read it for the first time in a few hours at a swim meet (the aptness of the setting wasn’t clear to me until Chapter 8) and probably would have finished sooner had it not been for the snatches of Eminem coming from somebody’s boombox. You can count the book’s speaking roles on your fingers, and any high school sophomore can skim it the night before the big exam. Assign that to millions of teenagers for sixty-odd years, and a Great American Novel is born.
What is it about the proposal that strikes me as so disturbing?’ Reading through an article describing a local government measure, I feel opposition rising within me. Normally, forming an opinion about such things would take me some time. But not here. The proposal instantly strikes me as unjust. My reaction is not just intellectual; it is visceral. My emotions are engaged. My imagination is exercised. As I imagine the proposal playing out in practice, the distinctive brand of injustice seems to be jumping out of every word on the page.
