New activity found for CHD7, a protein factor vital in embryonic development

Research by Kai Jiao, M.D., Ph.D., and colleagues at the University of Alabama at Birmingham and in Germany has yielded fundamental insights into the causes of severe birth defects known as CHARGE syndrome cases. These congenital birth defects include severe and life-threatening heart malformations.

Once in a lifetime floods to become regular occurrences by end of century

Superstorm Sandy brought flood-levels to the New York region that had not been seen in generations. Causing an estimated $74.1 billion in damages, it was the fourth-costliest U.S. storm behind Hurricane Katrina in 2005 and hurricanes Harvey and Maria in 2017 according to the National Oceanic and Atmospheric Administration. Now, due to the impact of climate change, researchers at Stevens Institute of Technology have found that 100-year and 500-year flood levels could become regular occurrences for the thousands of homes surrounding Jamaica Bay, New York by the end of the century.

After CDC guidance, little change in opioid prescriptions to those at risk of misuse

Why does it matter if most Republican voters still think Biden lost?

As President-elect Joe Biden and his administrative team officially begin the transition process, only about 20 percent of Republican voters consider him the true winner of the election. Nearly half of all respondents—48 percent—still expect President Donald Trump to be inaugurated for a second term on January 20, despite plenty of indicators to the contrary. Those are among the findings of the latest Bright Line Watch (November) survey—the political science research project of faculty at the University of Rochester, the University of Chicago, and Dartmouth College.
