Reducing methane emissions and testing AI-developed drugs

A Palo Alto-based startup wants to start releasing iron particles into the exhaust stream of an ocean freighter within the next 18 months.

Blue Dot Change hopes to determine whether these particles accelerate the destruction of methane, one of the most powerful greenhouse gases in the atmosphere.

It’s one of a handful of small commercial projects looking to test whether releasing similar particles could limit climate change. But little is known about the other effects of releasing particles, including potentially dangerous ones. Read full story.

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

At 82 years old, with a malignant form of blood cancer that six rounds of chemotherapy had failed to eliminate, “Paul” seemed left with no other choice. His doctors have enrolled him in a trial of a new technology that matches individual patients to the drug they need.

Two years later, Paul’s cancer was gone. The technology was developed by Exscientia, one of hundreds of startups exploring the use of machine learning in pharmaceuticals, with a shared vision of using AI for faster and cheaper drug discovery.

AI has been changing the way drugs are made. However, it’s still early days to spot AI drugs—and there are plenty of companies making claims that they can’t back it up. Read full story.
