Winners of the "Is the Reality Digital or Analog?" Essay Contest were announced on June 4, 2011 at the World Science Festival. The list of winners can be found here . Special thanks to our contest partners, the Gruber Foundation and Scientific American . Click here to read and comment on articles, blogs, and forums dealing with a wide range of foundational questions in physics and cosmology. FQXi catalyzes, supports, and disseminates research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlikely to be supported by conventional funding sources.

Mathematics is a tool used by scientists to help them construct models of how the universe works and make precise predictions that can be tested against observation. That is really all there is to it, but I had better add some more or this will be a really short essay.

Because of the overwhelming interest in our Plenary Conference "Paradigm Lost: Rethinking Economics and Politics," we have created a parallel event, YSI Commons , especially for graduate students, post-docs, and junior faculty. What is “YSI Commons”? YSI is INET's “Young Scholars Initiative,” and “Commons” refers to the intellectual commons that we all share, and also to the venerable “common room” of traditional universities, a central axis of scholarly society and culture.

NEW YORK (Reuters) - A former researcher at Amgen Inc has found that many basic studies on cancer -- a high proportion of them from university labs -- are unreliable, with grim consequences for producing new medicines in the future.

Multivitamin supplementation has been getting a rough ride in the literature, as evidence emerges that routine supplementation for most is, at best , unnecessary . Some individual vitamins are earning their own unattractive risk/benefit profiles: Products like folic acid , calcium , and beta-carotene all seem inadvisable for routine supplementation in the absence of deficiency or medical indication. Vitamin E, already on the watch list , looks increasingly problematic, with data recently published confirming the suspected association of supplementation with an elevated risk of prostate cancer.
