Reducing methane emissions, and testing AI-developed drugs

[ad_1]

A Palo Alto-based startup wants to start releasing metal particles into the exhaust stream of an ocean-going cruise ship within the next 18 months.

Blue Dot Change hopes to find out if the particles speed up the destruction of methane, one of the most powerful greenhouse gases in the atmosphere.

It’s one of the few small businesses itching to test whether emitting the same particles can curb climate change. But little is known about other effects of releasing particles, including potentially dangerous ones. Read the full story.

AI is dreaming up drugs that no one has ever seen before. Now we have to see if they work.

At age 82, with aggressive blood cancer that six rounds of chemotherapy had failed to eradicate, “Paul” seemed to have no choice. The doctors are experimenting with new technology that matches individual patients with the drugs they need.

Two years later, Paul’s cancer was gone. The technology was developed by Excintia, one of hundreds of startups looking at the use of machine learning in pharmaceuticals with the shared vision of using AI to make drug discovery faster and cheaper.

AI is already changing how medicine works. But it’s still early days for AI drug discovery—and many companies are making claims they can’t back up. Read the full story.
