If you were a weather forecaster for exoplanet GJ 1214b you would have an easy job. Today's forecast: cloudy. Tomorrow: cloudy. Extended outlook: more clouds.

Determining the weather on a distant planet around another star hasn't really been possible before. 

GJ 1214b is classified as a super-Earth type planet because its mass is intermediate between those of Earth and Neptune. Super-Earths like GJ 1214b are among the most common type of planets in the Milky Way galaxy but because no such planets exist in our Solar System, the physical nature of super-Earths is largely unknown.

A new paper in Nature estimates that global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions worldwide are not reduced -  due to a reestimate of the great unknowns of climate sensitivity, the role of cloud formation and whether this will have a positive or negative effect on global warming.

This new higher estimate was created using real world observations of water vapor in cloud formation. 

Scientists may have figured out how the molecular switch for sex gradually and adaptively evolved in the honeybee. It's been a long journey

While the number of killing frosts in southern Florida has remained unchanged since 1984, the number a short distance away declined enough that researchers are implicating global warming, and noted that the expansion of cold-sensitive mangrove forests along Florida's Atlantic Coast has led to them edging out salt marshes.

What happens when one ecosystem replaces another? Happens all of the time, of course, and has throughout history. But it's impossible to predict the result. People who live there are not complaining, though researchers up north are concerned.

An analysis from the University of Colorado School of Medicine shows patients with Medicaid insurance seeking care in an emergency department may be driven by lack of alternatives instead of the severity of their illness.

With the implementation of the Affordable Care Act, millions of new patients will be enrolled in Medicaid and added to an already overburdened primary care system. 

When it comes to the brain, there is very little science. fMRI imaging is subjective and pop psychology concepts even more so. Even when it comes to medical conditions, like schizophrenia, little is known. Its causes are unknown, there there is no objective test for it, and its diagnosis is based on an assortment of reported symptoms - and symptom-based diagnosis got replaced in most of medicine by the 1950s. The standard treatment, anti-psychotic medication, works less in less than half of those with a diagnosis and becomes increasingly ineffective over time.
