  • How HAWK beacons save pedestrians' lives

    Pedestrian-activated traffic signals that flash red to allow people to cross busy streets midblock have saved lives in one of the nation's most dangerous cities for pedestrians. On one stretch of Phoenix highway where three people were killed within one month, there have been no deaths in the three years since a HAWK beacon was installed. The city has installed 66 of the lights, supplemented by pedestrian education and traffic enforcement. Since 2018, pedestrian fatalities – which make up half of Phoenix's fatal accidents – have fallen by one-third.

  • Get There Fast or Safe? A Crowdsourced Map Gives You the Option

While the 100,000 or so users, more than half in India, constitute too small a user base to make the mapping app truly universal, its crowdsourced data already have prompted the Delhi and Bogota governments to improve street lighting on streets deemed unsafe because they are not well lit.

  • A New Project Is Bringing the Gay ‘Green Book' Online

    In 1965 a traveling salesman published a series of travel guides with gay or gay-friendly businesses across the U.S. that became survival guides for the LGBTQ community. “Mapping the Gay Guides” has digitized those collections, allowing users to explore the original descriptions and added historical content written by graduate students. Reasons for why locations appear and disappear from year-to-year are provided, which sometimes intersect with LGBTQ hate crimes. A $350,000 grant from the National Endowment for the Humanities will allow them to continue to preserve and make the forgotten history accessible.

One company is trying to speed up the process. Equinom, is a company that is using AI technology to select the best genes from each plant and then predict the outcomes.
