It can't have been easy for former environmental activist Mark Lynas to change sides. His friends were on the anti-science side, he was a dutiful reader of The Guardian, where activists and environmental trade groups reign supreme, and he was adored there.

But he had an ethical dilemma. How could he talk about the science consensus on climate change, despite generous potential funding by corporations to say otherwise (no, really, anti-science people think that happens), while continuing to deny the science consensus in agriculture. Exxon's revenue was 20X that of Monsanto and yet even with far fewer scientists in climate studies they were not "bought off" as his side claimed about farming.

Einstein could stick out his tongue but dinosaurs could not, according to a new paper. Instead of being like modern day lizards or legendary physicists, their tongues were probably rooted to the bottoms of their mouths like alligators. 

The discovery was made by comparing the hyoid bones — the bones that support and ground the tongue — of modern birds and crocodiles with those of their extinct dinosaur relatives. In addition to challenging depictions of dino tongues, the research proposes a connection on the origin of flight and an increase in tongue diversity and mobility.

Ice seems solid to the eye, but it is really a material that flows like a viscous liquid. In the polar ice sheets, it flows towards the oceans under its own weight. Knowing how fast the ice flows is of crucial importance to predict future sea level rises, especially if climate change occurs and impacts that.

For a new study, researchers used flow velocities at the surface of the northern Greenland Ice Sheet to create estimates and data from satellite images suggest that the polar ice is softer than scientists believed. 

Because Sudden Infant Death Syndrome (SIDS), in infants less than a year old, are tragedies without known explanation, scholars have searched for causes beyond stuffed animals in cribs or blaming parents.

SIDS represents up to 80 percent of all sudden unexpected infant deaths with an five in 1,000 live births in the US. The peak incidence occurs between two months and four months of age and is more common in boys. One explanation has been heart disease caused by genetic mutations but a recent study found that is less than 5 percent of cases, much lower than the 20 percent previously estimated.

“Diversity” as a concept has a lexical and political value all its own, with a widespread appeal. The problem with that is, however, that no one actually has the same idea of what diversity actually means. There is some consensus that the concept has, over time, morphed into something that it was not originally intended to be. Denise Green’s 2004 study looks at the University of Michigan’s response to a 1997 affirmative action case, and argues that legal precedents such as this one moved the cursor away from social and racial justice towards a narrower, simplified idea about diversity.

From a young age, children have a nuanced understanding of how free markets work. A new study in Child Development indicates that children as young as five incorporate market concerns—the idea that what you get is in line with what you give or offer—into their decision making, and increasingly do so with age.

Some people think children are innately selfish, they want to get goodies for themselves, while others insist they are more communist, each will do more to help those who can't or won't do enough. By studying how children engage in different types of exchanges, researchers hope to discern the origins of these behaviors, as well as their developmental course.

Cardiac arrest, essentially a heart attack, appears on a lot of coroner reports but it frequently misclassified and exaggerated. A new analysis finds that 40 percent of deaths attributed to cardiac arrest are not sudden or unexpected, and nearly half of the remainder are not arrhythmic--the only situation in which CPR and defibrillators are effective. Which means they should not be considered cardiac arrest. An alarming 13.5 percent were instead overdoses.

Pond scums were an animal’s best friend. 540 million years ago, oxygen was scarce in the atmosphere and ocean, and animals needed to find oxygen to make a livi

Meditation advocates from three schools say a lower ability to cope with the pain of being rejected by others leads to violence, but that people greater levels of mindfulness, a psychological fad where practitioners maintain attention on and awareness of the present moment -- are better able to cope with such pain. 

While preparing for another evening of observation of Jupiter's atmosphere with my faithful 16" dobsonian scope, I found out that the satellite Io will disappear behind the Jovian shadow tonight. This is a quite common phenomenon and not a very spectacular one, but still quite interesting to look forward to during a visual observation - the moon takes some time to fully disappear, so it is fun to follow the event.
This however got me thinking. A fully eclipsed jovian moon should still be able to reflect back some light picked up from the still lit other satellites - so it should not, after all, appear completely dark. Can a calculation be made of the effect ? Of course - and it's not that difficult.
