Business & markets

• The Federal Reserve raises its benchmark rate a quarter point to 3.75%-4% on September 16, its first hike since 2023, citing persistently elevated inflation; the FOMC votes 12-0 and its projections leave room for another increase this year.

Science & space

• Astronomers confirm Elias 2-24 b, a Jupiter-mass planet less than a million years old orbiting a star 450 light-years away, as the youngest planet ever found — the previous record-holders were all at least 5 million years old — in work led by Andrea Bernardi, a doctoral candidate at Universidad Diego Portales in Chile.

• A Washington University School of Medicine study of more than 333,000 veterans with type 2 diabetes finds cardiovascular risk climbs the longer patients stay off GLP-1 drugs like Ozempic and Wegovy after stopping — 4% higher at six months, 14% at one year, 22% at two years — with the lost benefit not fully restored even after resuming treatment.
