The US president, Donald Trump, moves to revoke the approval of New York City’s congestion pricing programs. We hear from one of the architects of the congestion charge policy in the city.

Microsoft has unveiled a new quantum chip called Majorana One, which it says will help the company create computers able to solve meaningful industrial-scale problems in years, not decades. And Roger Hearing discusses how a local government in the Philippines has come up with an unusual way of combating dengue fever by announcing a payment for every five mosquitoes caught and brought in.
