Heat pumps: 10 Breakthrough Technologies 2024
We’ve entered the era of the heat pump. Heat pumps are appliances that can cool and heat spaces using electricity. Many buildings today are still heated with fossil fuels, specifically natural gas. Switching to electric heat pumps that run on renewable energy could help them to cut their emissions dramatically.
While heat pumps have been used in buildings since the mid-20th century, the technology is breaking through in a new way. New approaches are enabling them to reach higher temperatures, which could allow the technology to help clean up industrial manufacturing. However, there are still big challenges ahead. Read the full story.
Heat pumps are one of MIT Technology Review’s 10 Breakthrough Technologies for 2024. Check out the rest of the list and vote for the final 11th breakthrough—we’ll reveal the winner in April.
If you’re interested in heat pumps, why not check out these other pieces by Casey:
+ Everything you need to know about the wild world of heat pumps. They’re the hottest home appliance, shoved into the spotlight by the potential for cost savings and climate benefits, as well as by recent policy incentives. Read the full story.
+ The surprising truth about which homes have heat pumps. The appliances buck a common climate technology trend in the US—for now. Read the full story.
The innovation that gets an Alzheimer’s drug through the blood-brain barrier
Therapies to treat brain diseases share a common problem: they struggle to reach their target. The blood vessels that permeate the brain have a special lining so tightly packed with cells that only very tiny molecules can pass through. This blood-brain barrier acts like a seal, protecting the brain from toxins or other harmful substances. But it also keeps most medicines out.
Researchers have been working on methods to sneak drugs past the blood-brain barrier for decades. And their hard work is finally beginning to pay off. Read the full story.

The big story
The Atlantic’s vital currents could collapse. Scientists are racing to understand the dangers.
Scientists are searching for clues about one of the most important forces in the planet’s climate system: a network of ocean currents known as the Atlantic Meridional Overturning Circulation. They want to better understand how global warming is changing it, and how much more it could shift, or even collapse.
The problem is the Atlantic circulation seems to be weakening, transporting less water and heat. Because of climate change, melting ice sheets are pouring fresh water into the ocean at the higher latitudes, and the surface waters are retaining more of their heat. Warmer and fresher waters are less dense and thus not as prone to sink, which may be undermining one of the currents’ core driving forces. Read the full story.
