Earth’s forests just grew 9% in a new satellite survey

The Age of Exploration may be long past, but even in the 21st century, our maps can still get a major update. Using satellite imagery, a new study has found hidden forests all over the world—almost enough for a second Amazon—in areas with little moisture known as drylands.


A new estimate of dryland forests suggests that the global forest cover is at least 9 percent higher than previously thought. The finding will help reduce uncertainties surrounding terrestrial carbon sink estimates.

They are diseases hidden in ice, and they are waking up

Throughout history, humans have existed side-by-side with bacteria and viruses. From the bubonic plague to smallpox, we have evolved to resist them, and in response they have developed new ways of infecting us.

However, what would happen if we were suddenly exposed to deadly bacteria and viruses that have been absent for thousands of years, or that we have never met before?


Five reasons blog posts are of higher scientific quality than journal articles

by Daniel Lakens, April 14, 2017

The Dutch toilet cleaner ‘WC-EEND’ (literally: ‘Toilet Duck’) aired a famous commercial in 1989 that had the slogan ‘We from WC-EEND advise… WC-EEND’. It is now a common saying in The Netherlands whenever someone gives an opinion that is clearly aligned with their self-interest. In this blog, I will examine the hypothesis that blogs are, on average, of higher quality than journal articles. Below, I present 5 arguments in favor of this hypothesis.  [EDIT: I’m an experimental psychologist. Mileage of what you’ll read below may vary in other disciplines].
