• Stanford researchers have developed a new way to estimate crop yields from space, using high-resolution photos snapped by a new wave of compact satellites.

    The approach, detailed in the Feb. 13 issue of Proceedings of the National Academy of Sciences, could help estimate agricultural productivity and test intervention strategies in poor regions of the world where data are currently extremely scarce.

  • Mt. Erebus is at the end of our world -- and offers a portal to another.

    It's our planet's southernmost active volcano, reaching 12,448 feet (3,794 meters) above Ross Island in Antarctica. Temperatures at the surface are well below freezing most of the year, but that doesn't stop visits from scientists: Erebus is also one of the few volcanoes in the world with an exposed lava lake. You can peer over the lip of its main crater and stare straight into it.

  • A tiny, transparent device that can fit into a contact lens has a bright future, potentially helping a range of scientific endeavors from biomedicine to geology.

  • Carmel Majidi and Jonathan Malen of Carnegie Mellon University have developed a thermally conductive rubber material that represents a breakthrough for creating soft, stretchable machines and electronics. The findings were published in Proceedings of the National Academy of Sciences this week.

  • Put a tray of water in the freezer. For a while, it’s liquid. And then—boom—the molecules stack into little hexagons, and you’ve got ice. Pour supercold liquid nitrogen onto a wafer of yttrium barium copper oxide, and suddenly electricity flows through the compound with less resistance than beer down a college student’s throat. You’ve got a superconductor.

  • People with hemophilia require regular infusions of clotting factor to prevent them from experiencing uncontrolled bleeding. But a significant fraction develop antibodies against the clotting factor, essentially experiencing an allergic reaction to the very treatment that can prolong their lives.

  • A very long time ago in a faraway galaxy, a star blew up. When the flash of light finally reached Earth on October 6, 2013, nobody noticed. Not at first. Three hours of supernova photons streamed by before an old telescope perched on a mountain north of San Diego started snapping pics.

  • Research from York University’s Lassonde School of Engineering, has found a new set of algorithms that can help determine the 3D structure of proteins to one day find new treatments for a range of diseases including Alzheimer’s, HIV and cancer. The research, published in the current edition of the journal Nature Methods, shows that these new algorithms rapidly generate 3-D structures of viruses, which could revolutionize the development of new drug therapies.

  • The new Space Environment In Situ Suite (SEISS) instrument onboard NOAA’s GOES-16 is working and successfully sending data back to Earth.

    A plot from SEISS data showed how fluxes of charged particles increased over a few minutes around the satellite on January 19, 2017. These particles are often associated with brilliant displays of aurora borealis at northern latitudes and australis at southern latitudes; however, they can pose a radiation hazard to astronauts and other satellites, and threaten radio communications.

  • A team of researchers, led by the University of Minnesota, has invented a new technology to produce automobile tires from trees and grasses in a process that could shift the tire production industry toward using renewable resources found right in our backyards.

    Conventional car tires are viewed as environmentally unfriendly because they are predominately made from fossil fuels. The car tires produced from biomass that includes trees and grasses would be identical to existing car tires with the same chemical makeup, color, shape, and performance.
