New Technology Needed to Monitor Rain Forest “Tsunami”
Human impact on tropical forest ecosystems has reached a “tsunami” stage, say scientists, and will require a new generation of sophisticated remote-sensing technology to monitor the changes. Speaking at a Smithsonian symposium Gregory Asner of the Carnegie Institution’s Department of Global Ecology presented new estimates of the global human impact on rain forests, including not only deforestation but also the extent of selective logging and forest regeneration.

Carnegie’s Larry Nittler Elected Meteoritical Fellow
Department of Terrestrial Magnetism (DTM) staff member Larry Nittler has been elected a fellow of the Meteoritical Society. Society fellows are “members who have distinguished themselves in meteoritics or allied sciences.” Just one percent of the membership can be elected by the society’s council on even-numbered years.

Classic Experiments Give New Insight on Life’s Origin
The building blocks of life may have emerged in volcanic eruptions on the early Earth, according to a new analysis of classic experiments performed more than fifty years ago. Using modern techniques to examine samples from the original experiments, researchers discovered previously undetectable organic compounds. The results, reported in the October 17 issue of Science, point to the possible contribution of volcanism to the beginning of life on Earth.

Carnegie’s Timothy Strobel to Receive Jamieson Award
Carnegie’s Geophysical Laboratory’s newest staff member, Timothy Strobel, will be given the prestigious Jamieson Award on September 26, 2011, from the International Association for the Advancement of High Pressure Science and Technology in Mumbai, India. The Jamieson Award is given to a scientist who has just completed outstanding PhD thesis research or to an exceptional postdoctoral researcher. Strobel’s research focuses on developing new hydrogen-based materials to meet our country’s energy challenges.

Carnegie’s Christoph Lepper Receives Prestigious Early Independence Award
Staff associate Christoph Lepper, at Carnegie’s Department of Embryology, is one of 10 recipients of the NIH Director’s Early Independence Awards. This is the first year of the awards. Lepper will receive a prize of $250,000 per year for five years to carry out his creative research program as an independent investigator. The prize is designed to launch exceptional young scientists into independent positions directly out of graduate school.

Studying crops, from outer space
Plants convert energy from sunlight into chemical energy during a process called photosynthesis. This energy is passed on to humans and animals that eat the plants, and thus photosynthesis is the primary source of energy for all life on Earth. New research uses satellite technology to measure light that is emitted by plant leaves as a byproduct of photosynthesis

Washington, D.C.—Physicists have long wondered whether hydrogen, the most abundant element in the universe, could be transformed into a metal and possibly even a superconductor—the elusive state in which electrons can flow without resistance. They have speculated that under certain pressure and temperature conditions hydrogen could be squeezed into a metal and possibly even a superconductor, but proving it experimentally has been difficult. High-pressure researchers, including Carnegie’s Ho-kwang (Dave) Mao, have now modeled three hydrogen-dense metal alloys and found there are pressure and temperature trends associated with the superconducting state—a huge boost in the understanding of how this abundant material could be harnessed. The study is published in the January 25, 2010, early, on-line edition of the Proceedings of the National Academy of Sciences.

Future Warming: Issues of Magnitude and Pace
Researchers reviewed the likelihood of continued changes to the terrestrial climate, including an analysis of a collection of 27 climate models. If emissions of heat-trapping gases continue along the recent trajectory, 21st century mean annual global warming could exceed 3.6 °F ( 2 °C) over most terrestrial regions during 2046 to 2065 and 7.2 °F (4 °C) during 2081-2100.At this pace, it will probably be the most rapid large climate change in the last 65 million years.

Magnesium oxide: From Earth to super-Earth
The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from a team led by Carnegie’s Stewart McWilliams studied how magnesium oxide behaves under the extreme conditions deep within planets and found evidence that alters our understanding of planetary evolution.

Carnegie Wins Grant to Preserve Historic Photos
The Carnegie Institution has been awarded a $9,400 grant from the Center for History of Physics, American Institute of Physics, to preserve and enhance access to a collection of historic photographs of scientific instruments and apparatus in the archives of the Department of Terrestrial Magnetism (DTM). The collection spans five decades from 1904 to the 1950s and includes thousands of images important to the history of geophysics, atomic physics, and astronomy.
