  • An urban farm nourishes the poorest part of Philly as its growers fight to keep the land

    The Life Do Grow Farm in Philadelphia, run by the nonprofit Urban Creators, is a two-acre plot that yields food needed to feed the community who might not be able to make ends meet. Since June, the farm has distributed 65,000 pounds of produce, along with free children’s meals. But the farm is also a community gathering space for artists and entrepreneurs. While the land’s lease runs out in 2022, the nonprofit hopes to own it and highlight it as a “reimagination of city land, a radical collaboration in the service of empowering Black and brown communities in North Central Philly,” said the farm manager.

  • How sunshine can make the railways greener

    As a way to reduce the amount of diesel fuel that powers trains, governments and transit companies around the world are turning to solar panels as a way to utilize renewable energy. In Australia, a solar train launched in 2017 that uses lithium-ion batteries that are charged by solar panels on the roof of the carriages. And a rail line in the United Kingdom uses energy from a solar farm to keep the train running. Scaling solar panels for nation-wide transit systems can be challenging, but many countries are committed to eliminating the use of fossil fuels on their rail networks.

  • Can an Algorithm Prevent Suicide?

    Veterans Affairs' Reach Vet program uses an algorithm weighing 61 factors to flag veterans deemed at highest risk of suicide. While its results have not been shown to affect the suicide rate, it has more than doubled high-risk veterans' uses of V.A. services and been associated with a lower overall mortality rate. Built on an analysis of thousands of previous suicides in the V.A.'s system, Reach Vet assesses scores of facts from medical records, including some that are not obvious to humans trying to spot problems. Doctors then intervene and ensure the veteran has a suicide safety plan in place.

  • These Algorithms Could Bring an End to the World's Deadliest Killer

    An app that uses A.I. to scans lung X-rays is helping two hospitals in rural and remote parts of India to identify cases of tuberculosis that they otherwise would have been likely to misdiagnose.

Her startup, KETOS, uses analytics and sensors that provide real-time data that can be sent through a mobile app. Instead of having to wait for people to monitor and process the data, or for people to get sick, data can be delivered instantaneously. “So far, the company has compiled 13 million data points from municipalities across all 50 states, spanning the last 18 years.”

  • Seattle's urban farmers are reclaiming public space

    Seattle’s urban agriculture community saw a boom during the COVID-19 pandemic and Black Lives Matter protests. BIPOC-led urban farms — like YES Farm and Black Star Farmers — had an increase in volunteers and people wanting to help provide food security, agricultural education, and land access to communities who don’t have their basic needs met. In the first half of 2020, the city of Seattle assigned plots of land to 439 new gardeners to pursue urban farming, with nearly half of them going to underrepresented populations.

  • Why Las Vegas Is at the Heart of Western States' Water Conundrums

    After running out of water during a drought in 2002, the Southern Nevada Water Authority and Las Vegas Valley Water District took proactive steps to conserve the region’s water for future generations. Thanks to public service campaigns, outdoor water usage limits, and turf replacement programs, the region’s water usage per capita has dropped by 46 percent. However, many people still don’t fully comply with the city’s water regulations and the region continues to grow at an expanding rate. Yet, similar conservation efforts could be a model for other arid regions around the United States.

  • Disinvested: How Government and Private Industry Let the Main Street of a Black Neighborhood Crumble

    A series of government programs designed to rebuild a neighborhood badly damaged by the 1968 Chicago uprising not only failed to achieve their goal, but actually made it worse. Hundreds of businesses in the Madison Street area of Chicago's West side were destroyed in days of rioting. Programs that emphasized clearing "blight" over building anew left vacant lots where new businesses might have emerged. Overall, "efforts turned out to be too scattered, too small and too susceptible to shifting politics to make a lasting impact," while opportunistic businesses cashed in without improving conditions.
