A Google artificial intelligence system was better than 6 radiologists at identifying whether patients had lung cancer, according to a new Nature Medicine study reported on by Stat News.

How it worked: When looking at a single CT scan, the algorithm detected 5% more cancers than the humans and reduced false positives by 11%. When prior images of patients were included in the evaluation, the algorithm performed the same as the radiologists.

Why it matters: Screening high-risk patients for lung cancer reduces the risk of death, but false positives can lead to unnecessary and potentially harmful surgeries.

  • About half of lung cancers are diagnosed after they have already spread.
  • "These people have a technology that will improve the precision of screening tremendously," Otis Brawley, an oncology professor at Johns Hopkins University, told Stat.

What next? The system will now be subject to further testing. Google acknowledged this, and said that it's already working with clinical partners and has had pre-submission discussions with the FDA.

Retailers have gotten really good at selling stuff online. So much so, investors want them to separate from the business units that do just that.

Why it matters: Spinning off these crown jewels may jeopardize both the physical and e-commerce sides of the companies in the long run by breaking the benefits of hybrid operations, analysts say.

U.S. envoy for the Horn of Africa Jeffrey Feltman will visit Khartoum this week amid what Prime Minister Abdalla Hamdok has called the “worst and most dangerous" crisis of Sudan’s transition to democracy, two sources with direct knowledge tell Axios.

Driving the news: Roughly 2,000-3,000 people had joined a sit-in in Khartoum as of this afternoon, per Reuters, after protesters massed over the weekend to call on the military to bring down the government. The protests came just four weeks after a failed military coup.

President Trump filed a lawsuit Monday seeking to block the National Archives from releasing White House records to the House select committee investigating the Jan. 6 Capitol insurrection, citing executive privilege.

Why it matters: It's the latest escalation in Trump's campaign to disrupt the committee's sweeping probe into the circumstances surrounding Jan. 6, including his actions and communications leading up to the Capitol attack.
