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.

Time to reconsider the relationship between science and the supernatural. A number of colleagues in both science and philosophy argue that the supernatural is nothing special, that god-related hypotheses can be tested by ordinary scientific methods, and that — given the repeated failure of such tests — the only rational conclusion is that science has pretty much shown that there is no such thing as the supernatural.

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. 

Breast reduction surgery has been linked to measurable improvements in several important areas of both physical health and quality of life, according to a new paper.

The study used the BREAST-Q© questionnaire, a well-validated survey instrument, to document the physical and psychosocial health benefits of breast reduction surgery. "The improvement in physical well-being is important for justification of insurance coverage," according to Dr. Michelle Coriddi and colleagues of Wexner Medical Center at the Ohio State University.

Researchers writing in Cell Regeneration report that they used induced pluripotent stem cells from urine to create a human tooth structure.

The integration-free human urine induced pluripotent stem cells were differentiated to epithelial sheets ( from the Greek meaning 'upon breast', since it was first considered the skin on the breast), one of the four types of tissue (others are nervous, muscle and collective tissue) and after 3 weeks they were able to get tooth-like structures using 8 different lines with a success rate of up to 30%. 

Though Oregon voters gave a thumbs down to a 2010 ballot measure to create state-certified marijuana dispensaries, the Legislature bucked that tyranny of the majority and made them legal this month.

Now the real work starts: how to certify them.
