TO THE EDITOR: The ultimate scientific mission of our community is to understand how the brain works in health and disease. Because the functions of the brain depend on molecular, cellular, and network level processes, achieving this goal requires the ability to directly interrogate those mechanisms. Doing such work in humans would require the development of noninvasive techniques at appropriat...

The abundance of supplemental material in The Journal of Experimental Medicine is growing. In the May 2011 issue of JEM, all research papers have a supplement, with an average of 5.9 supplementary items per paper. Only 3 yr ago (May 2008 issue), 16% of JEM papers had no supplementary items, and the overall average was 4.6 items per paper. 3 yr before that (May 2005 issue), 57% of papers had no ...

Structural and functional traits of organisms are known to be related to the size of individuals and to the size of their colonies when they belong to one. Among such traits, propensity to inquilinism in termites is known to relate positively to colony size. Larger termitaria hold larger diversity of facultative inquilines than smaller nests, whereas obligate inquilines seem unable to settle in...

Models of the untyped λ-calculus may be defined either as applicative structures satisfying a bunch of first order axioms, known as “λ-models”, or as (structures arising from) any reflexive object in a cartesian closed category (ccc, for brevity). These notions are tightly linked in the sense that: given a λ-model A, one may define a ccc in which A (the carrier set) is a reflexive object; conve...

The focus of this panel is the trade-off between excessive testing and acceptable shipped quality levels. How much testing is enough? We all strive to ship our customers high quality product, or at least product that meets our customers’ quality expectations. Often improvements in shipped quality levels can be made by plugging obvious holes in a device’s test suite, sometimes simply by increasi...

Growing Problem Solvers provides four original, related, classroom-ready mathematical tasks, one for each grade band. Together, these tasks illustrate the trajectory of learners’ growth as problem solvers across their years school mathematics.

People are often exposed to more information than they can actually remember. Despite this frequent form of information overload, little is known about how much information people choose to remember. Using a novel “stop” paradigm, the current research examined whether and how people choose to stop receiving new—possibly overwhelming—information with the intent to maximize memory performance. Pa...
