Exercise helps stave off depression. Swedish researchers genetically engineered mice to have high levels of a protein that builds up in muscles during exercise, then subjected these mice and a control group to sustained, low-level stress. After five weeks, the normal mice showed signs of depression, whereas the engineered mice did not. The researchers believe that the protein, PGC-1[alpha]1, helps turn a metabolite linked to depression into an acid that can be passed more easily out of the body. Co-author Jorge Ruas says the study proves that exercise should be prescribed for "the prevention and...

In these polarized times, it's always a relief to find something liberals and conservatives have in common — even if it has nothing to do with politics. New research suggests that, at least in Europe, people who lean decisively right or left get considerably more exercise than those in the center.
"Busy people at both ends of the political spectrum do not seem to have as much time for idleness," writes a research team led by Adrian Bauman of the University of Sydney's School of Public Health. In contrast, centrists do more sitting, "both on the fence and elsewhere."

MoreA bit over a week ago, the Committee for Skeptical Inquiry posted an open letter declaring that "Deniers are not Skeptics." To the Committee, skepticism is central to its goals, and it defines the activity as a careful analysis of evidence. As such, the group has been rather annoyed that people who doubt climate change have labelled themselves as skeptics, even if they have never taken the time to come to grips with any evidence.
The letter called for the news media to stop allowing doubters of climate change to use the label "skeptic" and instead label them deniers, based on the root "denial," which was defined as "the a priori rejection of ideas without objective consideration." In doing so, the Committee had the support of scientists and science communicators such as Bill Nye and Ann Druyan, the woman behind the latest version of Cosmos.
There's no shortage of denial when it comes to climate change—the public proclamations of Senator James Inhofe (R-Okla.), which the letter cites, are classic examples. And there's also genuine skepticism of individual scientific claims, as we saw by the response to a recent report by the National Oceanic and Atmospheric Administration on California's recent drought. But there are a whole host of things in between that make using any single label problematic.
