The study found that introductory statistics students who used R Markdown for homework assignments showed gradual gains in preference and no negative impact on grades.
A recent study by Ohio State University economists found that household wealth in the US has not recovered from the recession, with middle-aged people taking the biggest hit. The study contradicts the Federal Reserve's optimistic report from last summer, which suggested that net worth had recovered since the recession.
Researchers found that birds' choice of group size may be influenced by experimental design, rather than genetics. The study's conclusions are challenged due to errors such as regression to the mean and spatial fallacy.

A new analysis suggests that economic development can only buy happiness up to a certain level of wealth. Once income reaches around $36,000 GDP per capita, life satisfaction levels peak before dipping slightly in the very rich countries. This finding contradicts previous studies that showed a flat relationship between GDP and happiness.
Researchers in Denmark investigated oral fluoroquinolone use and found no association with an increased risk of retinal detachment.
