Pasadena, CA—The Carnegie Observatories announces the appointment of Professor Leopoldo Infante of Pontifica Universidad Católica (PUC) de Chile to direct the Las Campanas Observatories (LCO), high in the Atacama Desert in Chile. He will take the post July 31, 2017, succeeding Carnegie astronomer Mark Phillips who stepped in as interim LCO director when the previous director, Miguel Roth, retired in 2014.
People often call dogs “man’s best friend.” But after Elaine Ostrander’s presentation at our Washington, DC, headquarters Thursday, we think that moniker should probably be amended to “geneticist’s super-best friends.”
When it comes to studying basic genetics, dogs offer researchers an enormous advantage. This is because they have documented breeding histories, explained Ostrander, who is a top scientist at the National Institutes of Health.
During her program, “Dog Genes Tell Surprising Tales,” Ostrander broke down her dedication to studying the dog genome.
New work from a joint team of plant biologists and ecologists has uncovered the factor behind an important innovation that makes grasses—both the kind found in native prairies and the kind we’ve domesticated for crops—among the most-widespread plants on the planet. Their findings may enable the production of plants that perform better in warmer and dryer climate conditions.
Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. There is much about Earth’s ancient crust that scientists don’t understand. This is because most of the planet’s original crust simply isn’t around any longer to be studied directly—it has either sunk back into the planet’s interior due to the action of plate tectonics or been transformed by geological activity at Earth’s surface to make new, younger rocks
Recovered minerals that originated in the deep mantle can give scientists a rare glimpse into the dynamic processes occurring deep inside of the Earth and into the history of the planet’s mantle layer. A team co-led by Carnegie's Yingwei Fei has discovered a rare sample of the mineral majorite that originated at least 235 miles below Earth’s surface. Majorite is a type of garnet formed only at depths greater than 100 miles. Fascinatingly, the majorite sample Fei’s team found in Northern China was encased inside a regular garnet—like mineralogical nesting dolls.
Baltimore, MD—A first-of-its-kind study on almost 20,000 K-12 underrepresented public school students shows that Project BioEYES, based at Carnegie’s Department of Embryology, is effective at increasing students’ science knowledge and positive attitudes about science. Younger students had the greatest attitude changes. The study covered five years and tested students before and after the one-week BioEYES program.
Plants are currently removing more CO2 from the air than they did 200 years ago, according to new work from Carnegie’s Joe Berry and led by J. Elliott Campbell of UC Merced. The team’s findings affirm estimates used in models from the Intergovernmental Panel on Climate Change. “It may be tempting to interpret these results as evidence that Earth’s dynamics are responding in a way that will naturally stabilize CO2 concentrations and climate,” Berry explained. “But the real message is that the increase in photosynthesis has not been large enough to compensate for the burning of fossil fuels. Nature’s brakes are not up to the job. So now it’s up to us to figure out how to reduce the CO2 concentration in the atmosphere.”

Naturally occurring gene drive systems rig the inheritance game and cause some genes to be preferentially inherited, “driving” them out into the population. CRISPR gene-editing tools can be used...
