Researchers have created a brain test that can discover the source "of virtually any neurological infection," according to Scientific American.

For example, the test helped doctors to diagnose a brain tapeworm in a man from Nicaragua by identifying its DNA. The patient didn't have symptoms of the infection typically picked up by MRI scans.

How it works: Rather than look for a particular infection with a specific test, all of the DNA and RNA in a sample of cerebrospinal fluid is analyzed in order to identify foreign genetic material from viruses, bacteria, parasites or fungi. The challenge, researchers say, is "making sense of the output," but they've developed procedures for doctors to determine the most-likely cause of infection from the genomic data.

Coming soon: The researchers who developed the test at U.C. San Francisco will begin offering the test "as a custom-ordered service" to hospitals and labs across the U.S. on July 1.

An agreement between TikTok's Chinese owner ByteDance and Oracle includes a variety of concessions in an effort to make the deal palatable to the Trump administration and security hawks in Congress, according to a source close to the companies.

Driving the news: The deal, in the form of a 20-page term sheet agreed to in principle by the companies, would give Oracle unprecedented access and control over user data as well as other measures designed to ensure that Americans' data is protected, according to the source.

How the EU plans to take on human rights abusers

Amid a global assault on human rights stretching from Belarus to Hong Kong to Yemen, the European Union signaled yesterday that it may act to deter corrupt kleptocrats and state abusers by hitting them where it hurts: their assets.

Driving the news: Europe's chief executive Ursula von der Leyen revealed in her first-ever State of the Union speech that she will bring forth a European Magnitsky Act, a sanctions framework modeled after a U.S. law that restricts malign actors' access to travel and the global financial system.
