Researchers have devised a way to measure the internal properties of stars, a method that offers more accurate assessments of their orbiting planets. 

The astronomers examined HD 52265, a star  nearly 20 percent more massive than our Sun
 that is approximately 92 light years away. More than a decade ago, scientists identified an exopanet in the star's orbit. HD 52265 became an ideal model for both measuring stars' properties and how such properties can shed light on planetary systems.

Previously, scientists inferred stars' properties, such as radius, mass, and age, by considering observations of their brightness and color. Often these stars' properties were not known to sufficient accuracy to further characterize the nearby planets.

A statistical model based on risk factors says it can predict the probability (absolute risk) of a woman developing breast, ovarian, and endometrial (womb) cancer using easily obtainable information on known risk factors for these cancers.

A computer model estimate says it might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable "runaway greenhouse" stage. That may mean some planets thought to be habitable right now actually are not.

Fibromyalgia, widespread general muscle pain and fatigue, has no known causes or effective treatments but small-fiber polyneuropathy (SFPN) has a clear pathology and is known to be caused by specific medical conditions, some of which can be treated and sometimes cured.  

In a small group of patients with fibromyalgia, about half were found to have damage to nerve fibers in their skin and other evidence of small-fiber polyneuropathy. 

Researchers can argue about the accuracy of old thermometers and how to pick the datapoints of numerical models, but radio waves can help clear some things up.

The ionosphere, one of the regions of the upper atmosphere ionized by solar radiation, is used for the transmission of long-wave communications, like radio waves. And it turns out that radio waves reflecting back to Earth from the ionosphere offer valuable news on climate change.

Satellite observations made from 1982 to 2010 found that warm, arid regions are getting greener.
