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.

Calcium and reproduction go together
Everyone’s heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team reports discoveries in the chemical signaling process that guides flowering plant fertilization.

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.

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 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.

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.

Methane Emissions Vastly Surpass Previous Estimates
Government calculations of total U.S. methane emissions may underestimate the true values by 50 percent, a new study finds. The results cast doubt on a recent Environmental Protection Agency decision to downscale its emissions estimate.

Dr. Matthew P. Scott Joins the Carnegie Institution for Science as its 10th President
Dr. Matthew P. Scott joins the Carnegie Institution for Science as its 10th president September 1, 2014. Scott was Professor of Developmental Biology, Genetics, Bioengineering, and Biology at the Stanford University School of Medicine. He spent nearly 24 years at Stanford. The Carnegie board of trustees announced his appointment in May.

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 Partners with USA Science & Engineering Festival for Second Year
The world's largest celebration of science and engineering, the USA Science & Engineering Festival, will return to Washington, D.C., April 27-29, 2012. For the second year, the Carnegie Institution for Science will participate with hands-on experiments. At Carnegie's booth last year, visitors prospected for microscopic diamonds, handled a meteorite, constructed a spectroscope, examined fossils that are more than a billion years old, and met the scientists who do the work.

2005 Science Breakthrough: Revising Earth’s Early History
Researchers at the Carnegie’s Department of Terrestrial Magnetism (DTM) found that Earth’s mantle separated into chemically distinct layers faster and earlier than previously believed. Science magazine recognized the work in its December 23 issue, as one of the science breakthroughs for 2005...

Nectar: A sweet reward from plants to attract pollinators
Evolution is based on diversity, and sexual reproduction is key to creating a diverse population that secures competitiveness in nature. Plants had to solve a problem: they needed to find ways to spread their genetic material. Flying pollinators—insects, birds, and bats—were nature’s solution. To make sure the flying pollinators would come to the flowers to pick up pollen, plants evolved special organs called nectaries to attract and reward the animals. Yet despite the obvious importance of nectar, the process by which plants manufacture and secrete it has largely remained a mystery.

Decoding the chemical vocabulary of plants
Plants spend their entire lifetime rooted to one spot. When faced with a bad situation, such as a swarm of hungry herbivores or a viral outbreak, they have no option to flee but instead must fight to survive. What is the key to their defense? Chemistry. Understanding how plants evolved this prodigious chemical vocabulary has been a longstanding goal in plant biology.
