We would not expect a baby to join a team or participate in social situations that require sophisticated communication. Yet, most developmental biologists have assumed that young cells, only recently born from stem cells and known as “progenitors,” are already competent at inter-communication with other cells. New research shows that infant cells have to go through a developmental process that involves specific genes before they can take part in the group interactions that underlie normal cellular development and keep our tissues functioning smoothly.

A team of Carnegie scientists have found “beautifully preserved” 15 million-year-old thin protein sheets in fossil shells from southern Maryland.  The team—John Nance, John Armstrong, George Cody, Marilyn Fogel, and Robert Hazen—collected samples from Calvert Cliffs, along the shoreline of the Chesapeake Bay, a popular fossil collecting area. They found fossilized shells of a snail-like mollusk called Ecphora that lived in the mid-Miocene era--between 8 and 18 million years ago.

Lake Erie just can’t catch a break. The lake has experienced harmful algal blooms and severe oxygen-depleted “dead zones” for years, but now a team of researchers led by Carnegie’s Anna Michalak and Yuntao Zhou has shown that the widespread drought in 2012 was associated with the largest dead zone since at least the mid-1980s.

Quasars--supermassive black holes found at the center of distant massive galaxies--are the most-luminous beacons in the sky. These central supermassive black holes actively accrete the surrounding materials and release a huge amount of their gravitational energy. An international team of astronomers has discovered the brightest quasar ever found in the early universe, which is powered by the most massive black hole observed for an object from that time.

Carnegie announced today that it will receive Phase II funding through Grand Challenges Explorations, an initiative created by the Bill & Melinda Gates Foundation that enables individuals worldwide to test bold ideas to address persistent health and development challenges. Department of Plant Biology Director Wolf Frommer, together with a team of researchers from the International Rice Research Institute, Kansas State University, and Iowa State University, will continue to pursue an innovative global health research project, titled “Transformative Strategy for Controlling Rice Blight.”
