Neutrophils gone wild
Proteins are the new carbs On page 1691, Carlin et al. uncover a new tool of bacterial deception. Bacteria wear camouflage to creep through our bodies undetected. Some adorn their surfaces with sugary structures tipped with sialic acids that engage inhibitory receptors on white blood cells. Normally, these receptors, called Siglecs (Sia-recognizing Ig superfamily lectins), help the body recogni...
متن کاملExperimental evolution gone wild
Because of their large population sizes and rapid cell division rates, marine microbes have, or can generate, ample variation to fuel evolution over a few weeks or months, and subsequently have the potential to evolve in response to global change. Here we measure evolution in the marine diatom Skeletonema marinoi evolved in a natural plankton community in CO2-enriched mesocosms deployed in situ...
متن کاملBusy beavers gone wild
When considering a class of Turing machines that halt when started from a blank tape, busy beavers for that class, as coined by Tibor Radó, are those Turing machines which eventually halt after the maximum number of steps (or after producing the maximum number of non-blank symbols). Finding for a class of Turing machines the busy beaver champion (for any of the two competitions) is of course un...
متن کاملWild immunology.
In wild populations, individuals are regularly exposed to a wide range of pathogens. In this context, organisms must elicit and regulate effective immune responses to protect their health while avoiding immunopathology. However, most of our knowledge about the function and dynamics of immune responses comes from laboratory studies performed on inbred mice in highly controlled environments with ...
متن کاملIdentity-Based Encryption Gone Wild
In this paper we introduce a new primitive called identity-based encryption with wildcards, or WIBE for short. It allows to encrypt messages to a whole range of users simultaneously whose identities match a certain pattern. This pattern is defined through a sequence of fixed strings and wildcards, where any string can take the place of a wildcard in a matching identity. Our primitive can be app...
