It automates a type of safety evaluation for software systems known as red-teaming, which is typically done by a team of human testers. The aim is to find as many different ways to break or hijack a system as possible. OpenAI gave MIT Technology Review an exclusive peek into the system. Find out how it could keep the company ahead of human attackers.
—Will Douglas Heaven Why heat pumps are still so hot in the US —Casey Crownhart
It feels as if it should be illegal to even think about heating appliances during the height of summer, but we need to talk about heat pumps. The appliances use electricity for heating, they’re incredibly efficient, and they’re on the rise. In the US, their sales have doubled over the past 15 years, according to a new report. They’re also winning the heating race against fossil fuels, outpacing natural-gas furnaces by 32% during the first quarter of 2026. These stats are especially striking at this moment, because a key tax credit for heat pumps just ended. So why are heat pumps still so hot? Read the full story for the answer.
