Warmer weather, finer wines
By examining more than 500 years of harvest records, researchers found that wine grape harvests across France, on average, now occur two weeks earlier than in the past, largely due to climate change. While earlier harvests are normally associated with higher quality wines, researchers caution the trend likely won’t last.

Study that undercut psych research got it wrong
A study last year claiming that more than half of all psychology studies cannot be replicated turns out to be wrong. Harvard researchers have discovered that the study contains several statistical and methodological mistakes, and that when these are corrected, the study actually shows that the replication rate in psychology is quite high.
