    The first Drone as First Responder program in the U.S. expands the use of drone aircraft by the police, sending the aircraft on emergency calls without direct oversight by a human pilot. Using technology similar to self-driving cars, the drones deploy long-distance cameras and other sensors to observe things more quickly, safely, or efficiently than through traditional means. As more police departments adopt the equipment and tactic, privacy advocates warn of surveillance excesses that could harm over-policed populations.

  • A System for Sharing Household Heat Is Growing Beneath France

    In Paris, about 7,500 buildings are heated using geothermal energy, a cost-saving and carbon neutral energy source. Water is drawn from deep below ground at a central location and heated by the earth, and then sent via underground pipes to individual buildings. The Bagneux and Chatillon district has scaled up the system, providing heat to over 40,000 people. Districts created joint ventures to reduce construction costs and residents do not notice the energy source shift because when the temperature drops to a point where geothermal energy is not viable, gas boilers automatically keeps the heat flowing.

  • 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.

  • New Orleans actively releases videos of police shootings. Is it paying off with trust?

    Once viewed as one of the nation's most brutal and corrupt police departments, New Orleans Police Department has earned steadily improving public support with a host of reforms. One reform that it took voluntarily, and in contrast with common practice in Louisiana, is to quickly release body-camera videos of police shootings and other uses of force. Though its effect is hard to untangle from other initiatives, video releases have become routine. In one case, a video prompted an official apology after proving rubber bullets were used against protesters. This helped lead to new restrictions on crowd control.
