  9. X-ray eyes in the sky: New method for 3-D through-wall imaging that utilizes drones and WiFi

    06.19 / 20:20 phys.org Phys.org -Science news
    Researchers at UC Santa Barbara professor Yasamin Mostofi's lab have given the first demonstration of three-dimensional imaging of objects through walls using ordinary wireless signal. The technique, which involves two drones working in tandem, could have a variety of applications, such as emergency search-and-rescue, archaeological discovery and structural…
  10. Wildebeest feast: Mass drownings fuel the Mara River ecosystem

    06.19 / 19:22 phys.org Phys.org -Science news
    (Millbrook, NY) Each year, more than a million wildebeest migrate through Africa's Serengeti Mara Ecosystem. While crossing the Kenyan reach of the Mara River, thousands perish. A new study, published today in the Proceedings of the National Academy of Sciences, is the first to reveal how wildebeest drownings impact the ecology of the iconic…
