Researchers can now identify weak earthquakes within the continental U.S. with EarthScope’s USArray project, a network of 400 high-quality seismographs spaced every 70 kilometers. Each of these stations is temporarily installed at a given location for about two years and then assigned a new location as the footprint of the network moves from west to east in a regular grid pattern.
An interdisciplinary team of MIT researchers has grown a network of functioning blood vessels outside the body. The techniques developed by the MIT team will aid in growing vascular networks that provide blood flow to biological tissue, which is valuable in regenerative medicine—the development of artificial organs—and the design and testing of new drugs. Ultimately, this research could help save millions of lives.
