These new solid-state ACs promise a cool future. Scientists aren’t so sure.
After three years of record-breaking heat and another scorcher underway, air-conditioning isn’t going anywhere. That’s good for our health, but bad for the planet: it already accounts for 7% of global electricity use and 3% of greenhouse-gas emissions.
Feeling the heat, scientists and startups are hoping to amp up solid-state cooling. These systems move heat through conductive materials, which could cool spaces and surfaces with fewer messy side effects. The catch is whether it can match the efficiency of traditional AC.
Find out how the unconventional coolers aim to dial down AC emissions.

Job titles of the future: nature’s drug designer
In 2018, after nearly two decades working in Big Pharma, chemist Tim Cernak was ready to put his skills to a new use.
As a lifelong nature lover, he had become concerned that animals are often treated with human pharmaceuticals that can be harmful or even lethal. He decided to address this with a new approach: “conservation chemistry.”
Using AI tools and robots, he’s now rapidly designing and testing drugs for animals. Here’s what it takes to treat nature’s patients.

Quote of the day
“This action has taken the best models away from defenders, created market uncertainty, and risked America’s AI leadership without any real risk to justify it.”
—Cybersecurity leaders urge the Trump administration to reverse restrictions on Anthropic’s most advanced AI models in an open letter.
One More Thing
How scientists want to make you young again
A little over 15 years ago, scientists at Kyoto University made a remarkable discovery. When they added just four proteins to a skin cell and waited about two weeks, some of the cells underwent an unexpected and astounding transformation: they became young again.
Now, after more than a decade of developing this cellular reprogramming, biotech companies and research labs have tantalising hints that the process could be the gateway to an unprecedented new technology for human age reversal.
Read the full story on their efforts to “reprogram” aging bodies back to youth.
