How much of a reef’s ability to withstand stressful conditions is influenced by the type of symbiotic algae that its corals hosts? New work from a team including Carnegie's Arthur Grossman investigates how the the abundance and diversity of nutrients that algae share with their coral hosts varies between species and what this could mean for coral’s ability to survive in a changing climate. The research team determined that in the wake of a bleaching event, even an algal tenant that’s poor provider may be better than no provider.
Dr. Eric Isaacs Begins as 11th President of the Carnegie Institution for Science
Dr. Eric D. Isaacs begins his tenure as the 11th president of the Carnegie Institution on July 2, 2018. Isaacs joins Carnegie from the University of Chicago where he has been the Robert A. Millikan Distinguished Service Professor, Department of Physics and the James Franck Institute Executive Vice President for Research, Innovation and National Laboratories.

Earthquakes, floods, tsunamis, hurricanes, and volcanoes—they all stem from the very same forces that give our planet life. It is only when these forces exceed our ability to withstand them that they become disasters. Science and engineering can be used to understand extreme events and to design our cities to be resilient, but we must overcome the psychological drive to normalization that keeps humanity from believing that we could experience anything worse than what we have already survived.
The interactions that take place between the species of microbes living in the gastrointestinal system often have large and unpredicted effects on health, according to new work led by Carnegie’s Will Ludington, who assembled a team of biologists, physicists, and mathematicians to comprehensively reveal the gut microbiome ecosystem of fruit flies.
A supernova discovered by an international group of astronomers including Carnegie’s Tom Holoien and Maria Drout, and Carnegie alumnus Ben Shappee of the University of Hawaii, provides an unprecedented look at the first moments of a violent stellar explosion. The light from the explosion's first hours showed an unexpected pattern, which Carnegie's Anthony Piro analyzed to reveal that the genesis of these phenomena is even more mysterious than previously thought.
Carnegie’s Anna Michalak was a major contributor to the U.S. Global Change Research Program’s Second State of the Carbon Cycle Report released last Friday, which provides a current state-of-the-science assessment of the carbon cycle in North America—including the United States, Canada, and Mexico—and its connection to climate and society.

An international team including five Carnegie astronomers has discovered a frozen Super-Earth orbiting Barnard’s star, the closest single star to our own Sun. The Planet Finder Spectrograph on Carnegie’s Magellan II telescope was integral to the discovery, which is published in Nature. To find this cold Super-Earth, the team combined 20 years of data from seven different instruments, all of which were “stitched” together to form one of the largest and most-extensive datasets ever used for this method of planet detection.

Almost half of our DNA is made up of jumping genes, moving around the genome in developing sperm and egg cells. Given their ability to jump around the genome, their invasion can trigger DNA damage and mutations often leading to animal sterility or even death and threatening species survival. Organisms have survived these invasions, but little is known about where this adaptability comes from. Now, Carnegie researchers have discovered that reproductive stem cells boost production of non-coding RNA elements that suppress jumping gene activity and activate a DNA repair process allowing for normal egg development.
The Earthbound Planet Search Program has discovered hundreds of planets orbiting nearby stars using telescopes at Lick Observatory, Keck Observatory, the Anglo-Australian Observatory, Carnegie's Las Campanas Observatory, and the ESO Paranal Observatory. Our multi-national team has been...
The Zheng lab studies cell division including the study of stem cells, genome organization, and lineage specification. They study the mechanism of genome organization in development, homeostasis—metabolic balance-- and aging; and the influence of cell morphogenesis, or cell shape and...
The recent discovery that the universe is expanding at an accelerating rate has profoundly affected physics. If the universe were gravity-dominated then it should be decelerating. These contrary results suggest a new form of “dark energy”—some kind of repulsive force—is...

HABITABILITY: WHAT EARTH AND THE INNER PLANETS CAN TEACH US ABOUT THE SEARCH FOR LIFE ON ROCKY EXOPLANETS
What enabled life to form on Earth—and what kept it at bay on...
Seismic waves flow through Earth’s solid and liquid material differently, allowing Earth scientists to determine various aspects of the composition of the Earth’s interior. Broadband seismology looks at a broad spectrum of waves for high-resolution imaging. Lara Wagner collects this...
Scientists simulate the high pressures and temperatures of planetary interiors to measure their physical properties. Yingwei Fei studies the composition and structure of planetary interiors with high-pressure instrumentation including the multianvil apparatus, the piston cylinder, and the diamond...
Guillermo Blanc wants to understand the processes by which galaxies form and evolve over the course of the history of the universe. He studies local galaxies in the “present day” universe as well as very distant and therefore older galaxies to observe the early epochs of galaxy...
