You're probably not racist. As the world has gotten smaller, race as a bias has become less of a thing. Yet there is a test - the Implicit Association Test - that is guaranteed to show you are racist and weak observational studies that use it end up in a lot of mainstream media stories.

Now there may be a way to cure it.

When the Bárðarbunga volcano beneath Iceland's Vatnajökull ice cap reawakened in August 2014, scientists got an opportunity to monitor how the magma flowed through cracks in the rock away from the volcano.

 Although it has a long history of eruptions, Bárðarbunga has been increasingly restless since 2005, including a dynamic period in August and September of this year, when more than 22,000 earthquakes were recorded in or around the volcano in just four weeks, due to stress being released as magma forced its way through the rock. 

Are umpires biased? There has been sociological woo produced trying to prove they are racist in baseball but a paper has found that if a cricket team has home umpires, some bias does get introduced, at least in Test cricket, the longest form of the sport .

Though drugs spend years in development and hundreds of millions or even billions of dollars are spent in increasingly demanding clinical trials before approval, a lot of prescription drugs get added warning labels - or can even be withdrawn - after release to the public because of hidden toxicity that clinical trials did not find. 

A new toxicity test invented at the University of Utah could make it possible to uncover dangerous side effects earlier in pharmaceutical development.

In the United States in the 1930s, climate change and droughts and excessive agricultural practices combined to give the country a 'Dust Bowl' - as farmers became more stressed during the Depression they farmed harder, so ancient agricultural practices got left behind.

Modern agricultural science is a little smarter. Scientists make sure farmers know the right application for pesticides and when it comes to biotech crops, they make sure pests don't develop 'herd immunity'.

Though some see snowstorms and believe global warming has been exaggerated, a new study using predictions of Greenland ice loss and its impact on rising sea levels instead finds that other models may be greatly underestimating it.  

The new estimate simulates future distribution of lakes that form on the ice sheet surface from melted snow and ice, called supraglacial lakes. Previously, the impact of supraglacial lakes on Greenland ice loss had been assumed to be small, but the new research has shown that they will migrate farther inland over the next half century, potentially altering the ice sheet flow in dramatic ways.

A new study says that delaying the cutting of the umbilical cord in newborns by two minutes leads to a better development of the baby during the first days of life - by influencing the resistance to oxidative stress in newborns.

How much science is in pop music? Can pop culture enhance science communication?

A sociology duo recently explored the occurrence of science in the lyrics of Taiwanese pop music. Their results revealed that expressions from the field of astronomy and space research are notably prominent in the lyrics. Most texts address emotional states, while the latest scientific topics are only rarely mentioned.

“In many countries, and that includes Austria in particular, there is a distinct gap between the sciences and the population, which must be bridged. Popular culture and the entertainment media, amongst others, could play a valuable part as intermediaries,” says co-author Joachim Allgaier.

Some people eat when they are hungry and stop when they are not. Others eat until they are full. For that second group, science may soon have a way to help keep them slimmer.

Inulin-propionate ester (IPE) contains propionate, which stimulates the gut to release hormones that act on the brain to reduce hunger. Propionate is produced naturally when dietary fiber is fermented by microbes in the gut and in its first tests in humans, researchers found that the ingredient is effective at preventing weight gain in overweight volunteers.
