In defense of air-conditioning

technologyreview.com Casey Crownhart 2026-01-16 15:00:00

We should all be aware of the growing electricity toll of air-conditioning, but the AC hate is misplaced. Yes, AC is energy intensive, but so is heating our homes, something that’s rarely decried in the same way that cooling is. Both are tools for comfort and, more important, for safety. So why is air-conditioning cast as such a villain? In the last days of June and the first few days of July, temperatures hit record highs across Europe. Over 2,300 deaths during that period were attributed to t

CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle

gizmodo.com Gayoung Lee 2026-01-18 10:00:42

All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,

There could be “dark main sequence” stars at the galactic center

arstechnica.com Unknown 2026-01-19 11:30:58

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It's so well understood that scientists have devised a "main sequence" that acts a bit like a periodic table for stars, correlating their mass and age with their properties. The main sequence, however, is based on an assumption that's almost always true: All of the energy involved comes from the gravity-driven fusion of lighter elemen
