A new study found that mice can run 100 minutes longer without any training when given a certain compound named GW1516, per The Verge. That has scientists hoping they can turn the compound into a drug to help people who have trouble exercising due to disabilities or health issues.

How it works: Scientists injected the compound into mice and it activated their PPAR gene, making it more difficult for them to gain weight. The mice also responded better to insulin, making it less likely for them to become diabetic. (The PPAR gene can also be activated through regular exercise.)

The stats: Mice in the control group ran about 160 minutes before their blood sugar dropped below a certain level, while the GW-injected mice were able to run for 270 minutes.

The caveat: The drug hasn't been tested on humans, and miracle drugs that promote weight loss without exercise don't have a great track record.

The head of Instagram will find himself in Congress' crosshairs for the first time Wednesday in the one area lawmakers have shown they are willing to pass tech regulations — protecting youngsters online.

Why it matters: Republicans and Democrats have found common ground in grilling tech companies on how their products harm children, especially after revelations in The Wall Street Journal about Instagram's potential harm to the mental health of teen girls.

The Jan. 6 select committee plans to move forward with contempt proceedings against former White House chief of staff Mark Meadows for his refusal to comply with the panel's subpoena.

Why it matters: The committee has used the threat of contempt — and the associated financial and reputational costs — to try to ensure evasive witnesses sit for their depositions.

Complaint to FTC: Amazon search results full of potentially deceiving ads

Amazon does not sufficiently distinguish between its search results and paid ads, potentially "deceiving millions of consumers," according to a complaint filed to the Federal Trade Commission.

Why it matters: Joan Moriarty, research director for the Strategic Organizing Center, a coalition of labor unions that filed the complaint, told the Washington Post the group is "very hopeful" that the FTC will investigate the complaint because Lina Khan (D), a known Amazon critic, is now chair.
