Autism Guidance Released

Federal officials yesterday announced a possible association between the development of autism and a pregnant individual's use of acetaminophen, the active ingredient in the common over-the-counter pain reliever Tylenol. They recommended pregnant individuals limit use of the drug to cases such as high fever or severe pain. 

The Food and Drug Administration said it will update safety labels with the risks of acetaminophen. However, the agency added that while there may be an association between autism and the drug, current scientific evidence has not established a causal relationship. Scientists have researched a potential link between autism and acetaminophen for years, but studies have delivered mixed results. The FDA also approved leucovorin as a possible treatment for autism symptoms.

Autism is a developmental condition affecting how people communicate, interact socially, and process information. Reported autism diagnoses in the US (see CDC data) have risen since 2000, with about 1 in 31 children and 1 in 45 adults diagnosed today. Factors include improved diagnostic criteria and expanded screening. 

 

TikTok Deal Details

The White House yesterday outlined a preliminary deal to place TikTok’s US operations under American control, with some of the country’s largest tech and media companies at the helm. The move seeks to avert a ban on the Chinese-owned social media app over national security and privacy concerns.

Under the proposal, TikTok's parent company, ByteDance, would license its content recommendation algorithm to a US investor group that includes private equity firm Silver Lake and software giant Oracle. Oracle would also oversee platform security and the algorithm. Over the weekend, President Donald Trump said Dell CEO Michael Dell and Fox Corporation leaders Rupert and Lachlan Murdoch are likely involved in the deal, too. ByteDance would reportedly hold one seat on US TikTok’s seven-member board.

Trump is expected this week to delay a TikTok ban for the fifth time as ByteDance and the US investors finalize the deal. See a timeline of TikTok’s US history here.

 

NASA's New Class

NASA unveiled the 10 newest members of its astronaut corps yesterday, a group winnowed down from more than 8,000 applicants from across the US. The group, the first to include more female candidates than male, will now undergo two years of training before becoming flight-eligible. 

While missions are not predetermined, the timeline of the agency’s ambitious Artemis program may see the new class become the first to dock with the Lunar Gateway, a planned space station orbiting the moon. The outpost is a key step in NASA’s plan to establish an ongoing presence on the lunar surface and a milestone toward a potential trip to Mars. Read a Reddit “Ask Me Anything” with the group posted yesterday.

The class is the 24th since the program’s creation, bringing the total number of astronauts in NASA history to 370. Read about the first-ever class in 1959, known as the “Mercury Seven.”
