Principal investigator Sean Solomon, also of Carnegie, made the announcement at the first plenary of the 26th science team meeting in Vancouver, British Columbia.
Geochemist Richard Carlson of Carnegie’s Department of Terrestrial Magnetism has been elected a member tof the National Academy of Sciences (NAS). He is among 84 new members and 21 foreign associates of one the most prestigious honorary societies in the country.
Carnegie Institution for Science president Richard A. Meserve has been elected president of the Harvard Board of Overseers for 2012-2013. The Overseers provide advice and approvals of important actions about educational policies and practices. Members are elected by Harvard and Radcliffe graduates for six-year terms. Meserve has been a member of the Board of Overseers since 2007. The article about the election appears in the April 30, 2012, Harvard Gazette.
The American Society for Plant Biology (ASPB) awarded Wolf B. Frommer, director of Carnegie’s Department of Plant Biology, the Lawrence Bogorad Award for Excellence in Plant Biology Research for “his major contributions in the development of fundamental tools and technologies essential for breakthrough discoveries that advance our understanding of glucose, sucrose, ammonium, amino acid, and nucleotide transport in plants.”

Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world’s most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant’s brain. Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind research on the more visible parts of plants. But now: a new technology--developed jointly by Carnegie and Stanford University--could revolutionize root research.
In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are likely to be discovered. New research from a team including Carnegie’s Alan Boss narrows down the search for Earth-like planets near Jupiter-like planets. Their work indicates that the early post-formation movements of hot-Jupiter planets probably disrupt the formation of Earth-like planets.
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars they come from and how the explosions happen. New research from a team led by Harvard University and including Carnegie’s Josh Simon, Chris Burns, Nidia Morrell, and Mark Phillips examined 23 Type Ia supernovae and helped identify the formation process for at least some of them.
Insect glands are responsible for producing a host of secretions that allow bees to sting and ants to lay down trails to and from their nests. New research from Carnegie scientists focuses on secretions from glands in the reproductive tract that help sperm survive and guide the sperm on the trip to fertilize an egg. The gene that controls the development of these glands in fruit flies provides important information about gland development in all insects, as well as potential clues to similar human reproductive glands.
For the first time, astronomers have detected the presence of arsenic and selenium, neighboring elements near the middle of the periodic table, in an ancient star in the faint stellar halo that surrounds the Milky Way. Arsenic and selenium are elements at the transition from light to heavy element production, and have not been found in old stars until now.
