The late William F. Buckley famously said he’d rather be governed by the first 2,000 people in the Boston phone book than by the faculty of Harvard University. No one, to my knowledge, ever asked him to choose between the Berkeley phone book and the UC Berkeley faculty. I suspect the conservative Buckley would have held his nose and opted for the faculty – if only in hopes that a few right-wing economists might compensate for the liberal yahoos that he imagined made up the rest of the professoriat, to say nothing of the population at large.

The Ethics of a Psychologist

In 2002, Seligman spent three hours at Naval Base San Diego, lecturing on torture and interrogation. But his lectures, he protests, were flipped on their head: he told the group of military men and women how to resist torture and interrogation by an unscrupulous foe. According to Mayer, the military used his insights to learn to induce in victims a condition of “learned helplessness” — a type of forlorn passivity that Seligman first observed in randomly electrocuted dogs 40 years ago. He hasn’t collaborated with that group since the lecture, he says, and he strongly condemns torture. “My career has been devoted to finding out how to overcome learned helplessness, not how to produce it.”

Fallout Holidays

The opening scene of the newest Indiana Jones film is set in Nevada in 1957, possibly during Operation Plumbbob, an actual nuclear-test series in which the U.S. measured the response of humans and physical structures to nuclear blasts. Satellite images give a hint of what’s left: a pockmarked brown landscape of craters and broken buildings. There are smashed reinforced-concrete domes, shattered windows, as well as iron rails and bridges that the heat and explosion have twisted. It looks, I am told, like a place where Superman (or perhaps Uri Geller) had given himself over to a fit of rage.

Panic Attack

Originally appeared The New York Sun.

Once, I had occasion to yell “Fire” in a crowded theater. I was on crutches at the time, and at a reception after an opening-night performance of “The Dybbuk.” While leaning against a wall and eating a smoked-salmon canapé, I felt heat on my lower back. Smelling smoke, I craned my head to see a small candle igniting my shirt, and flames licking their way up toward my collar. The reactions around me were diverse and instructive. A woman shrieked, and a man laughed. But neither did anything. I picked up my crutches, hobbled to the open bar and asked them to douse me. Incredibly, the barmaid started by daintily pressing ice cubes against the flames, until I suggested that she just drench me with the contents of her bucket.

Yucca Mountain High

The word “mountain” has lovely connotations: icy streams, conifer forests, unblemished views of a snowy sierra, yodeling competitions. (OK, so not they’re not all lovely.) Alas for Yucca Mountain, these images of alpine sweetness do not apply to it at all. If Yucca Mountain had a name that conveyed just how baking-hot, barren, forlorn, and lifeless it is — perhaps “Yucca Death Vault” would do it justice — more people might see the logic in the government’s plan, now nearly thirty years old, to use it to store the nation’s radioactive garbage. The mountain is dry, geologically appropriate, and far enough from human settlements to keep it secure in case of accident or attack. Nevadans and anti-nuke activists object and say that the risk of leaks, of terrorist attacks, and of unforeseen catastrophes is too great to allow Yucca Mountain to accept the waste. But the waste has to go somewhere, and Yucca Mountain is the right spot.

The alternative, first of all, is to keep the waste at the nuclear plants that produce it. Yucca Mountain is equipped to accept 77,000 tons of radioactive waste, which are currently distributed all over the country, often in areas near population centers. Few if any of the current nuclear plants could provide the security of a mountain in the middle of the country’s most inhospitable and militarized desert.

Scientists, engineers, politicians, and lawyers have bickered for decades about whether Yucca is seismically inert enough to ensure millennia of safe storage. I don’t blame skeptics for doubting. Storage beyond the scale of individual human lives, to say nothing of human history, is tricky and bound to pose risks, such as slow bleeds of radioactive waste into the ground or water. The good news is that the worst of the waste will have decayed significantly within centuries, and the scariest parts of what’s left — plutonium, which takes 24,000 years to decay by half — can be kept out of deep storage and instead reprocessed to power more reactors (or build bombs, about which more below). Now that storage and fossil-fuel costs are skyrocketing, this sort of reprocessing will make increasing economic sense, thereby reducing the period during which Yucca Mountain would have to be certified secure.

Finally, the subject of bombs: The most ridiculous fears surround the possibility that someone would seize any stored plutonium and use it build a bomb. Let’s assume a dramatic raid of Yucca Mountain actually did occur, and somehow the folks next door at Nellis Air Force Base were powerless to stop it. The terrorists would then have loads of fission fragments, plus a large quantity of the same material used to incinerate Nagasaki. That improbable outcome would not be good, but it wouldn’t be terrible, because contrary to its reputation, plutonium is neither all that dangerous nor all that difficult to get. It’s not available, as Dr. Emmett Brown predicted over half a century ago, “in every corner drugstore,” but nuclear power plants routinely produce the stuff as a waste product, and at last count there were nuclear plants all over the world, mostly not in the U.S. The trick isn’t getting the plutonium, but turning it into a bomb. (Enriched uranium is the opposite — hard to find, easy to blow up.)

Yucca Mountain won’t avert all catastrophes — whether of the bang or the whimper variety. But it will be better than the status quo.

The Bacteria Within Us

Originally published in the New York Sun.

The poet William Blake imagined what it would be like “to see the world in a grain of sand.” Reading “Microcosm” (Pantheon, 243 pages, $25.95), Carl Zimmer’s new book on the world’s most famous bacterium, one wonders whether Blake might have phrased his reverie differently if he had had an electron microscope. Had Blake looked closely enough, at a magnification that would make sand grains look like lifeless, barren mountains, the poet would have seen a remarkably complex creature, one so beguiling that it is, as Mr. Zimmer’s title suggests, easy to imagine it as a world in miniature. The bacterium, whose genome scientists mapped fully by 1997, fights viruses, just as we do; it fights its enemies, just as we do; it even has a primitive kind of sex. It is, the author argues persuasively, a model organism, and one with much to teach our own species.

A Desert Moistened

The classic evidence for a wet Sahara comes from the Tassili frescoes, a series of fifty Algerian cave paintings that depict humans living with crocodiles, buffalo, giraffes, and other animals that do not thrive in arid climates. Ten thousand years ago, it appears, our ancestors could have grown rice in the Sahara, or spent their weekends Jet-Skiing at their North African lake-houses. For millennia, they had no reason to fear their water running out, or their settlements’ being reclaimed by desert sands, or of water running out. What the new reports about this bizarre climatological period don’t much emphasize, though, is that the Sahara was wet during a period of comparative global heat, and that it became parched only as the planet chilled.

Steak Without Cow

PETA’s million-dollar prize is an occasion for irony — delicious or repulsive, depending on one’s perspective. About a decade ago, an urban legend claimed that the government had barred Kentucky Fried Chicken from calling its food “chicken,” because it used genetically modified Frankenbirds, brainless and grown in jars, that bore no resemblance to chicken or poultry of any kind. That supposedly explained the rebranding of Kentucky Fried Chicken as “KFC” — a government demand for truth in advertising. Needless to say, this idiotic myth contained not even a grain of truth. KFC continued to use real chickens, and to abuse them wantonly in the production process. PETA noticed and launched a campaign, “Kentucky Fried Cruelty,” to draw attention to KFC’s brutal methods. Now PETA’s prize suggests the organization wishes the urban legend had been true from the start. One looks forward to clever PETA graphics featuring Colonel Sanders in a lab-coat, instead of bloodstained and sporting devil-horns.
