Ozone-depleting compound persists, NASA research shows

August 21, 2014 8:48 am | by EurekAlert! | News | Comments

NASA research shows Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide. Carbon tetrachloride (CCl4), which was once used in applications such as dry cleaning and as a fire-extinguishing agent, was regulated in 1987 under the Montreal Protocol along with other chlorofluorocarbons that destroy ozone and contribute to....

Where are all the women in STEM?

August 11, 2014 10:57 am | by Kasey Panetta, Managing Editor and Eileen Whitmore, Art Director | Blogs | Comments

When it comes to women in STEM (science, technology, engineering, mathethmatics) the numbers just don’t add up. Even though the number of women majoring in STEM (and attending college) has increased in the past few decades, the number of women who actually enter the fields has barely increased at all. There probably isn’t one reason behind the dearth of women, but hopefully all the sciences will see an influx of women soon.
