Three Things You Need to Know Today

A Dark Secret at the Heart of AI
Can you trust an intelligent entity that can’t explain its reasoning? Humans have never really built machines they don’t fully understand before, but the world’s most advanced algorithms now teach themselves and yet can't communicate how they do it. As these black box systems begin to drive cars, diagnose disease, and make financial decisions, that could become a huge problem. Our own Will Knight went on a journey to the bleeding edge of AI research and philosophy to find out how we can tackle the problem.

The Government’s War on Botnets
A prolific botnet has fallen. Following the arrest of Russian hacker Peter Levashov in Spain over the weekend, the Justice Department announced that the FBI is dismantling the Kelihos botnet that he controlled. The army of weaponized computers, at times numbering 100,000 devices, was rented out to criminals who wanted to steal login details, send spam e-mail, and perform ransomware attacks. The news is a clear signal that the U.S. government is doubling down on one of the most pernicious cyber threats of the day—but it still has plenty of work to do.

Energy Industry CO2 Emissions Continue to Fall
Electricity production is getting greener. New figures show that U.S. energy-related CO2 emissions fell by 1.7 percent in 2016—the second year they’ve fallen, and part of a decade-long trend. The reason, says the Energy Information Administration: decreased use of coal, increased use of renewables and shale gas, and warmer weather that led to reduced power demands. It’s good news, especially as the economy also grew over the same period—but there’s still a way to go, as global CO2 concentrations continue to rise faster than ever.
