Hitler's World by Timothy Snyder [New York Review of Books]
In Hitler’s world, the law of the jungle was the only law. People were to suppress any inclination to be merciful and were to be as rapacious as they could. Hitler thus broke with the traditions of political thought that presented human beings as distinct from nature in their capacity to imagine and create new forms of association. Beginning from that assumption, political thinkers tried to describe not only the possible but the most just forms of society. For Hitler, however, nature was the singular, brutal, and overwhelming truth, and the whole history of attempting to think otherwise was an illusion. Carl Schmitt, a leading Nazi legal theorist, explained that politics arose not from history or concepts but from our sense of enmity. Our racial enemies were chosen by nature, and our task was to struggle and kill and die.
Cheetahs’ Secret Weapon: A Tight Turning Radius [New York Times]
"Anyone who has watched a cheetah run down an antelope knows that these cats are impressively fast. But it turns out that speed is not the secret to their prodigious hunting skills: a novel study of how cheetahs chase prey in the wild shows that it is their agility — their skill at leaping sideways, changing directions abruptly and slowing down quickly — that gives those antelope such bad odds."
First Evidence Found for Photosynthesis in Insects: [nature.com] "The biology of aphids is bizarre: they can be born pregnant and males sometimes lack mouths, causing them to die not long after mating. In an addition to their list of anomalies, work published this week indicates that they may also capture sunlight and use the energy for metabolic purposes."
"The next time you hear a bird chirping outside your window, you might think twice about what’s going on inside his little birdbrain."
Are birds’ tweets grammatical? [Scientific American] But are the rules of grammar unique to human language? Perhaps not, according to a recent study, which showed that songbirds may also communicate using a sophisticated grammar—a feature absent in even our closest relatives, the nonhuman primates. Kentaro Abe and Dai Watanabe of Kyoto University performed a series of experiments to determine whether Bengalese finches expect the notes of their tunes to follow a certain order.
