Hannah Thomasy in The Scientist:
Worldwide, more than three million people lose their lives each year to lung-damaging conditions like chronic obstructive pulmonary disease or cystic fibrosis.1 In contrast, fewer than 5,000 individuals per year are fortunate enough to receive life-saving lung transplants.2 Transplant recipients still face many challenges, however, including a lifetime of immunosuppressant medications with potentially severe side effects and a more than 40 percent transplant failure rate in the first five years.3
In a recent study in Science Translational Medicine, transplantation immunologist Rainer Blasczyk and his team at the Hannover Medical School presented a potential solution to these problems in a minipig model.4 Instead of administering immunosuppressants, which Blasczyk likened to blinding the patient’s immune system, leaving the individual vulnerable to infections and even certain types of cancer, the researchers suppressed key immune proteins in the donor lung, rendering it immunologically invisible.5 Modifying the organ instead of the recipient isn’t a new idea, but it is an important one, said Jeffrey Platt, a transplantation biologist at the University of Michigan Medical School who was not involved in this work. “If you can introduce something that will affect the donor organ, then you can preserve the immune system of the recipient. And in lung transplantation, that’s really important because the lung is one of the first targets of infectious organisms.”

For a while there in the late nineties, it seemed to me like every other book of poetry that I flipped open in the bookstore was prefaced by an austere epigraph from the writings of Ludwig Wittgenstein. Plato, Rousseau, Nietzsche, Sartre, and Wittgenstein—for all their many differences—enjoy a special status as “poets’ philosophers” in the annals of literary history. Other lofty thinkers fly under poets’ collective radar; I have yet to come across a volume of verse prefaced by a quotation from David Hume. What makes some philosophers, and not others, into poets’ philosophers remains a mystery to me. But I’ve never really thought of Hannah Arendt as one of them.
If a change of style is a change of subject, as Wallace Stevens averred, then a change of syntax is a change of meaning. Word order is, if not all, then nine tenths. I exaggerate, but I do so advisedly, as a corrective to the overemphasis on word choice, the unjust rule of the mot juste (recall here the old saying about the difference between lightning and a lightning bug) that dominates, to the detriment of other concerns, contemporary literature and creative writing. At times, this passion for the right—or the unusual—word reaps dividends; at others, it merely produces an uncalled-for flood of verbed nouns, portmanteaus, adjectives wrenched out of joint.

The key structure of the doctrine of nuclear deterrence is audible in the September 4, 2024, speech by U.S. Deputy Under Secretary of Defense Cara Abercrombie: “Any nuclear attack by the DPRK against the United States or its allies and partners is unacceptable and will result in the end of that regime.” The doctrine, which the United States has embraced since the Cold War, aims to prevent an adversary from launching a nuclear weapon by assuring that any first strike will be followed by a retaliatory second strike, whose effects will equal or exceed the original damage and may eliminate the adversary altogether. This annihilating reflex of deterrence is equally audible in the quiet words of the Department of Defense in its web page on “America’s Nuclear Triad,” its sea-based, land-based, and air-based delivery platforms: “The triad, along with assigned forces, provide 24/7 deterrence to prevent catastrophic actions from our adversaries and they stand ready, if necessary, to deliver a decisive response, anywhere, anytime.”

George Parkin Grant, who died in 1988 at the age of 69, was world-famous in Canada—at least, that was the jest frequently made at the philosopher’s expense. The joke reflected his status as a public intellectual who made frequent appearances on Canadian Broadcast Corporation radio programs but never attracted much attention south of the 49th parallel. There are many reasons for his obscurity outside his home country, but one cause was surely his intense Canadian nationalism, coupled with his outspoken criticism of the form of liberalism he saw embodied in the hegemon to the south.
In the chilling speech he gives at the end of the film Margin Call, Jeremy Irons says that no one should say they believe in equality, because no one really thinks it exists: The very idea camouflages the endurance of hierarchy in an essentially unchanging form. “It’s certainly no different today than it’s ever been,” he explains to an underling. “There have always been and there always will be the same percentage of winners and losers….
