News feature: Capturing cancer's complexity.
Looking down from an airplane window, it’s hard to appreciate the diversity of plants that thrive in a lush forest thousands of feet below. The shade of green might hint at a dominant species, but what else is mixed in? And what’s growing below those highest treetops? Cataloguing the trees at the edge of the forest is also little help. Is the other side of the forest the same? It’s nearly impos...
متن کاملNews Feature: Radiation redux.
WhenMichael Postow started his fellowship training in medical oncology at the Memorial Sloan Kettering Cancer Center (MSKCC) in 2010, he wasn’t familiar with the term “abscopal.” Coined decades before he was born and then largely forgotten by physicians, it describes a phenomenon in which radiation delivered at one site in the body has an effect on distant tissues that are, literally, “outside”...
متن کاملNews Feature: Secret life.
Before NASA launched its Viking landers to Mars in 1975, Carl Sagan suggested that the Red Planet might harbor “organisms ranging in size from ants to polar bears.” Afterward, he acknowledged that nothing in the landers’ images could be taken as a sign of advanced life. There was one rock, however, that appeared to be inscribed with the letter “B.” But Sagan held off on any sort of celebration....
متن کاملNews Feature: Code wars
In October 2014, an Antares rocket blasted off from a NASA launch pad on one of Virginia’s barrier islands, and exploded seconds later. In addition to about 5,000 pounds of food and equipment destined for the International Space Station, the doomed rocket was carrying 26 miniature satellites called CubeSats, one of which housed physicist Alexander Ling’s experiment. “We thought, ‘oh, that’s it,...
متن کاملProgramming Languages Capturing Complexity Classes
We investigate an imperative and a functional programming language. The computational power of fragments of these languages induce two hierarchies of complexity classes. Our first main theorem says that these hierarchies match, level by level, a complexity-theoretic alternating space-time hierarchy known from the literature. Our second main theorems says that a slightly different complexity-the...
