Yesterday, Boston-based autonomous vehicle technology company Optimus Ride announced a new partnership with real estate company Brookfield Properties to introduce Optimus Ride's self-driving vehicles to Brookfield properties around the world. The first location will be the 36-acre Halley Rise mixed-use development near Reston, Va., where, beginning in June, Optimus Ride will introduce three vehicles to transport tenants from their offices to parking lots around the site. According to a press release, an on-site operations team will provide maintenance and oversight of the vehicles. [Optimus Ride]

Researchers from the University of Pennsylvania (U Penn), the University of Illinois at Urbana–Champaign, and the University of Cambridge, in England, have developed a porous "metallic wood" material made of nickel that is as strong as titanium, but four times as light. "The reason we call it metallic wood is not just its density, which is about that of wood, but its cellular nature,” said study lead and U Penn engineering assistant professor James Pikul. “Cellular materials are porous; if you look at wood grain, that’s what you’re seeing—parts that are thick and dense and made to hold the structure, and parts that are porous and made to support biological functions, like transport to and from cells.” [University of Pennsylvania]

Polish physicist Olga Malinkiewicz has developed a new perovskite solar cell inkjet processing method, which allows for the creation of solar panels at much lower temperatures and at a significantly reduced cost. The resulting coating—which can be applied to buildings, spacecraft, cars, or even laptops—is light, flexible, and available in varying levels of transparency. [AFP]
