Scientists Tackle the Carbon Conundrum
Scientists, including Carnegie's Anna Michalak, have developed a new, integrated, ten-year science plan to better understand the details of Earth’s carbon cycle. It identifies new research areas such as the role of humans as agents and managers of carbon cycling and climate change, the direct impact of greenhouse gases on ecosystems including changes to plant and animal diversity and ocean acidification, the need to address social concerns, and how best to communicate results to the public and decision makers.

Consumption, carbon emissions, and international trade
Accurately calculating the amount of carbon dioxide emitted in the process of producing and bringing products to our doorsteps is nearly impossible, but still a worthwhile effort, two Carnegie researchers claim in a commentary published online this week. The Global Ecology department’s Ken Caldeira and Steven Davis commend the work of industrial ecologist Glen Peters and colleagues, published in the same journal late last month, and use that team’s data to do additional analysis on the disparity between emissions and consumption in different parts of the world.

Australia Gets $72 Million for the GMT
The Australian government has announced that it will provide $88.4 million AUD ($72.4 million USD) to help fund the revolutionary 25-meter Giant Magellan Telescope (GMT) to be sited at Las Campanas Observatory in Chile’s high-altitude Atacama Desert. This brings the funding that has been raised to date to $200 million out of approximately $700 million total needed to complete construction, which is scheduled for 2019.

Astronomers find puzzling dwarf star with complex magnetic fields
Typically, little M-dwarf stars—the most common type of star in the galaxy—are cold, quiet, and dim. Now a team of astronomers led by Edo Berger, a Carnegie-Princeton postdoctoral fellow, found one M-dwarf that doesn’t conform. It has an unusually active and complex magnetic field, stronger than our own Sun’s, and a huge hot spot that covers half of its surface.

Expansion of Space Measurement Improved
A team of astronomers, led by Wendy Freedman, director of the Carnegie Observatories, have used NASA's Spitzer Space Telescope to make one of the most accurate and precise measurement yet of the Hubble constant, a fundamental quantity that measures the current rate at which our universe is expanding.

Climate: Meat turns up the heat
Eating meat contributes to climate change, due to greenhouse gasses emitted by livestock. New research finds that livestock emissions are on the rise and that beef cattle are responsible for far more greenhouse gas emissions than other types of animals.

Major Changes Needed For Coral Reef Survival
To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie’s Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be engulfed in inhospitable ocean chemistry conditions by the end of the century if civilization continues along its current emissions trajectory.

Dr. Matthew P. Scott Named 10th President of the Carnegie Institution for Science
By unanimous vote of the Carnegie Board of Trustees, Dr. Matthew P. Scott has been appointed the 10th president of the Carnegie Institution for Science. Dr. Scott is Professor of Developmental Biology, Genetics, Bioengineering, and Biology at the Stanford University School of Medicine and will succeed the current President, Dr. Richard A. Meserve, on September 1, 2014.
“This is an extraordinary time for the Carnegie Institution for Science”, said Co-Chairs Suzanne Nora Johnson and Stephen Fodor. “The scientific departments are flourishing with strong support from Trustees and a well performing endowment. The Trustees and Departmental Directors all believe Dr. Scott captures the independent spirit of Carnegie Science’s long tradition of leading science at the frontiers. We are enthusiastic about his leadership.”

Planet-like object may have spent its youth as hot as a star
Astronomers have discovered an extremely cool object that could have a particularly diverse history—although it is now as cool as a planet, it may have spent much of its youth as hot as a star. The current temperature of the object is intermediate between that of the Earth and of Venus. However, the object shows evidence implying that a potentially large change in temperature has taken place. In the past this object would have been as hot as a star for many millions of years.

Adults lack stem cells for making new eggs
Mammalian females ovulate periodically over their reproductive lifetimes, placing significant demands on their ovaries for egg production. Whether mammals generate new eggs in adulthood using stem cells has been a source of scientific controversy. If true, these “germ-line stem cells” might allow novel treatments for infertility and other diseases. However, new research from Carnegie’s Lei Lei and Allan Spradling demonstrates that adult mice do not use stem cells to produce new eggs.

Spectacular Heating of Planet Observed
Here on Earth we worry about our planet's atmosphere warming by a few degrees on average over the next century, and even weather fronts bring temporary changes in temperature of no more than tens of degrees. Now astronomers writing in the January 29 Nature
report on an extra-solar planetary system where global warming is taken to a spectacular extreme: a 700 degree rise in a few hours.

Earth’s getting “soft” in the middle
A new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly, suggesting that the material there is softer than previously thought.

Hot-Spring Bacteria Flip a Metabolic Switch
Scientists at the Carnegie Institution’s Department of Plant Biology have found that photosynthetic bacteria living in scalding Yellowstone hot springs have two radically different metabolic identities...

Airlock-like transport protein structure discovered
New work has for the first time elucidated the atomic structures of the bacterial prototype of sugar transporters, termed “SWEET” transporters, found in plants and humans. These bacterial sugar transporters are called SemiSWEETs, because they are just half the size of the human and plant ones. The findings have potential practical applications for improving crop yields as well as for addressing human diseases such as diabetes.

Disappearing and reappearing superconductivity surprises scientists
Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials at low temperatures, or can be induced under chemical and high external pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission. New work demonstrates unexpected superconductivity in a type of compounds called iron selenium chalcogenides.

Carnegie Wins DOE Energy Frontier Research Center Award
The Carnegie Institution’s Geophysical Laboratory has been selected as one of 46 Energy Frontier Research Centers (EFRCs) by the U.S. Department of Energy. The five-year, $15.0 million award will establish the Energy Frontier Research in Extreme Environments center (EFree) at the Geophysical lab. The selection was based on the lab’s long legacy of research into materials under extreme pressure and temperature environments.

Superconductivity is a rare physical state in which matter is able to conduct electricity—maintain a flow of electrons—without any resistance. This phenomenon can only be found in certain materials under specific low-temperature and high-pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission. New research found unexpected superconductivity that could help scientists better understand the structural changes that create this rare phenomenon.
