Pasadena, CA— You can never predict what treasure might be hiding in your own basement. We didn’t know it a year ago, but it turns out that a 1917 image on an astronomical glass plate from our Carnegie Observatories’ collection shows the first-ever evidence of a planetary system beyond our own Sun.
New work from an international team including Carnegie’s Ken Caldeira demonstrates that the planet’s remaining fossil fuel resources would be sufficient to melt nearly all of Antarctica if burned, leading to a 50- or 60-meter (160- to 200-foot) rise in sea level. Because so many major cities are at or near sea level, this would put many highly populated areas where more than a billion people live under water, including New York City and Washington, DC. It is published in Science Advances.
Stanford, CA— Four additional members of Stanford University’s faculty have been named Honorary Adjunct Staff Scientists at Carnegie’s Department of Plant Biology. Stanford’s Dominique Bergmann has been a Carnegie adjunct since 2011, and the newly added adjunct staff brings the total number with this honorary title to five.
Planet-hunting is an ongoing process that’s resulting in the discovery of more and more planets orbiting distant stars. But as the hunters learn more about the variety among the tremendous number of predicted planets out there, it’s important to refine their techniques. New work led by Carnegie’s Jonathan Gagné, Caltech's Peter Gao, and Peter Plavchan from Missouri State University reports on a technological upgrade for one method of finding planets or confirming other planetary detections.
Washington, DC—New work from a research team led by Carnegie’s Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field.
Baltimore, MD—New work from Carnegie’s Allan Spradling and Lei Lei demonstrates that mammalian egg cells gain crucial cellular components at an early stage from their undifferentiated sister cells, called germ cells. This mechanism had previously only been documented in lower animals, and may be a key to understanding the egg’s unique properties. Their work is published via Science First Release.
Washington, DC— A new study, based on the most-extensive set of measurements ever made in tide pools, suggests that ocean acidification will increasingly put many marine organisms at risk by exacerbating normal changes in ocean chemistry that occur overnight. Conducted along California’s rocky coastline, the study from Carnegie’s Ken Caldeira and Lester Kwiatkowski shows that the most-vulnerable organisms are likely to be those with calcium carbonate shells or skeletons.
The genome editing system called CRISPR earned Science magazine’s “2015 Breakthrough of the Year.” The advent of facile genome engineering using the bacterial RNA-guided CRISPR-Cas9...
