The Lyda Hill Foundation, in partnership with Geena Davis's Institute on Gender in Media at Mount Saint Mary's University, released an extensive research report on the portrayals of female characters in science, technology, engineering and math in television and film. 'Portray Her: Representations of Women STEM Characters in Media' shows that entertainment media has a long way to go to improve stereotypes about pursuing STEM careers.

A new study, led by UNSW Sydney PhD student Rose O'Dea, has explored patterns in academic grades of 1.6 million students, showing that girls and boys perform very similarly in STEM - including at the top of the class.

Brazilian researchers dated the families using a numerical simulation method to process current data to go back in time to the asteroid formation era.

A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research describes the limitations of prediction models used by electricity providers and regulators for medium- and long-term energy forecasting. It outlines a new model that includes key climate predictors that researchers say present a more accurate view of how climate change will alter future electricity demands.

A research team led by Arun Iyer, Ph.D., assistant professor of pharmaceutical sciences in the Eugene Applebaum College of Pharmacy and Health Sciences at Wayne State University, has developed a nanoplatform technology that works in combination with existing chemotherapeutic drugs that may reverse drug-resistance in renal cell carcinoma.

Consumers' credit cards are declined surprisingly often in legitimate transactions. One cause is that fraud-detecting technologies used by a consumer's bank have incorrectly flagged the sale as suspicious. Now MIT researchers have employed a new machine-learning technique to drastically reduce these false positives, saving banks money and easing customer frustration.

"We used our data-driven tools to derive significant insight into how the process works that allows us to design the correct additives to get the desired outcomes," Sigman said. The results allow chemists to control which stereochemical product comes out of the reaction, simply by selecting the right ligand. It's more than just a laboratory convenience, though. The study also reveals much more about how this important chemical process works.
