AI is helping scientists model molecules

This artist s conception symbolically represents complex organic molecules, known as polycyclic aromatic hydrocarbons, seen in the early universe. These large molecules, comprised of carbon and hydrogen, are considered among the building blocks of life.

Google updated one of its most potent artificial intelligence applications, an AI model called AlphaFold — and the latest version can model “all of life’s molecules,” the company said last week. Yeah, all of them.

While the previous version of the model could simply predict the structures of proteins, Alpha Fold 3 can actually model DNA and RNA, plus small molecules called ligands. Google’s DeepMind and Isomorphic Labs divisions, which worked on AlphaFold, said the new model is a 50% improvement over the last one.

“It tells us a lot more about how the machines of the cell interact,” John Jumper, a Google DeepMind researcher, told The New York Times. “It tells us how this should work and what happens when we get sick.”

With this technology, researchers can leap ahead in the fundamental techniques they use to model biological systems, test and develop new drugs, and build new materials. Google is letting researchers around the world use the model through a website called AlphaFold Server for any non-commercial research. Here’s hoping we can report on the first lifesaving drugs developed through AI soon.

Whether it's baseball brawls or political polarization, social media gives us all a warped picture of the world. Why is that, and what can we do about it? Senior Writer Alex Kliment takes a look.

Fewer than two weeks after Hurricane Helene devastated the southeastern United States, killing at least 230 people and causing billions of dollars in damage, Hurricane Milton hit Florida late Wednesday, causing multiple deaths, destroying homes, and bringing with it tornadoes, waves approaching 30 feet, and a thousand-year flood in the St. Petersburg area. Over 3 million in the state are without power. Before Milton made landfall, experts estimated the storm could cause between $50 and $175 billion in damage, with insurers on the hook for up to $100 billion.

The US presidential election is just over three weeks away – and it’s a close race. According to the 538 election model, Harris is currently projected to win 53 out of 100 times in its simulations compared to Trump’s 47 victories – and in a tiny fraction of the simulations, there is no electoral college winner, the ultimate chaos scenario.
