Their result shows the importance of not taking anything for granted, said Noga Alon, a mathematician at Princeton. “We have to be suspicious, even about things that intuitively look very likely to be true.” Gladkov, Pak, and Zimin found many small-graph examples that satisfied the conjecture, but in the end, those did not reflect the […]
“It’s a great algorithm,” said Erik Demaine, a computer scientist at the Massachusetts Institute of Technology. “It’s very fast, simple, and easy to implement.” To put this procedure into practice, you’d need to decide on a system for organizing your notes—a data structure, in the lingo of computer science. That may sound like a minor […]
“It provides a natural framework, or a bookkeeping mechanism, to assemble very large numbers of Feynman diagrams,” said Marcus Spradlin, a physicist at Brown University who has been picking up the new tools of surfaceology. “There’s an exponential compactification in information.” Carolina Figueiredo, a graduate student at Princeton University, noticed a striking coincidence where three […]
When England’s team exposed caterpillars to electric fields similar to those generated by a flying wasp, caterpillars displayed defensive behaviors such as coiling, flailing, or biting. “This basically insinuates,” England said, that “prey and predator can detect each other just using static electricity.” Dornhaus, the behavioral ecologist, questioned whether electroreception buys the caterpillar much time. […]
To study the cell membranes of deep-sea animals, the biochemist Itay Budin (center) joined forces with marine biologists Steve Haddock (right) and Jacob Winnikoff (left). Photographs: From left: Tamrynn Clegg; Geoffroy Tobe; John Lee “They are looking into an area that, to a large degree, has not been explored,” said Sol Gruner, who researches molecular […]
