The Harvard RoboBee has long shown it can fly, dive, and hover like a real insect. But what good is the miracle of flight without a safe way to land?
Red roses, the symbol of love, were likely yellow in the past, indicates a large genomic analysis by researchers from Beijing Forestry University, China. Roses of all colors, including white, red, pink, and peach, belong to the genus Rosa, which is a member of the Rosaceae family.
Reconstructing the ancestral traits through genomic analysis revealed that all the roads trace back to a common ancestor —a single-petal flower with yellow color and seven leaflets.
The findings are published in Nature Plants.
At the Seismological Society of America’s Annual Meeting, researchers posed a seemingly simple question: how wide are faults?
Using data compiled from single earthquakes across the world, Christie Rowe of the Nevada Seismological Laboratory at the University of Nevada, Reno and Alex Hatem of the U.S. Geological Survey sought a more comprehensive answer, one that considers both surface and deep traces of seismic rupture and creep.
By compiling observations of recent earthquakes, Rowe and Hatem conclude that from Turkey to California, it’s not just a single strand of a fault but quite often a branching network of fault strands involved in an earthquake, making the fault zone hundreds of meters wide.
