The seven biggest problems facing science, according to scientists

In the past several years, many scientists have become afflicted with a serious case of doubt — doubt in the very institution of science... So we sent scientists a survey asking this simple question: If you could change one thing about how science works today, what would it be and why? We heard back from 270 scientists all over the world, including graduate students, senior professors, laboratory heads, and Fields Medalists. They told us that, in a variety of ways, their careers are being hijacked by perverse incentives. The result is bad science.

The Reproducibility Project out of UVa recently published their findings in Science: Estimating the reproducibility of psychological science
We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. ... The mean effect size (r) of the replication effects (Mr = 0.197, SD = 0.257) was half the magnitude of the mean effect size of the original effects (Mr = 0.403, SD = 0.188), representing a substantial decline. Ninety-seven percent of original studies had significant results (P < .05). Thirty-six percent of replications had significant results;
