Leading scientists, senior officials, and supporters from an international consortium of universities and research institutions are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope (GMT).
Stanford, CA—Everyone who took high school biology learned that photosynthesis is the process by which plants, algae and select bacteria transform the Sun's energy into chemical energy during the daytime. But these photosynthetic organisms activate other biochemical pathways at night, when they generate energy by breaking down the sugars, starches, and oils that they created during the day.
New observations from an international geophysics team, including Carnegie’s Lara Wagner, suggest that the standard belief that the Earth’s rigid tectonic plates stay strong when they slide under another plate and sink into the deep Earth may not be universal. Instead, the new work suggests that the Nazca slab in Perú may be relatively weak and deforms easily.
As astronomers continue finding new rocky planets around distant stars, high-pressure physicists are considering what the interiors of those planets might be like and how their chemistry could differ from that found on Earth. New work from a team including three Carnegie scientists demonstrates that different magnesium compounds could be abundant inside other planets as compared to Earth.
The American Society for Cell Biology profiles Yixian Zheng and her recent papers on the elusive spindle matrix. "Zheng’s lab identifies new regulators in spindle assembly, all associated with the spindle matrix, a structural scaffold that promotes mitosis.The problem here is that some scientists aren’t convinced that the spindle matrix exists. In one of these new papers, Zheng begs to differ." More
A pair of researchers have new evidence to support a link between cyclical comet showers and mass extinctions, including the one that they believe wiped out the dinosaurs 66 million years ago. NYU's Michael Rampino and Carnegie's Ken Caldeira traced 260 million years of mass extinctions and found a familiar pattern: Every 26 million years, there were huge impacts and major die-offs. More

Traditionally studies of brain function have focused on task-evoked responses. By their very nature such experiments tacitly encourage a...
The Curiosity rover has been exploring Mars for more than three years, measuring the past and present habitability potential of our nearest planetary neighbor. We’ve also been busy on Earth,...
