Expect the Unexpected From the Delta Variant
This much is clear: The coronavirus is becoming more transmissible. Ever since the virus emerged in China, it has been gaining mutations that help it spread more easily among humans. The Alpha variant, first detected in the United Kingdom last year, is 50 percent more transmissible than the original version, and now the Delta variant, first detected in India, is at least 40 percent more transmiss

How to Hold Trump Accountable

Who do we invent for? Patents by women focus more on womens health, but few women get to invent
Women engage in less commercial patenting and invention than do men, which may affect what is invented. Using text analysis of all U.S. biomedical patents filed from 1976 through 2010, we found that patents with all-female inventor teams are 35% more likely than all-male teams to focus on women's health.

First months decisive for immune system development
Many diseases caused by a dysregulated immune system, such as allergies, asthma and autoimmunity, can be traced back to events in the first few months after birth. To date, the mechanisms behind the development of the immune system have not been fully understood. Now, researchers show a connection between breast milk, beneficial gut bacteria and the development of the immune system.
