Gas near the starburst core of dwarf galaxy NGC 4214 is moving the wrong way: absorption lines show it redshifted up to 30 km/s, falling inward instead of blowing out. Combined with a warped, disturbed HI disk seen by VLA and FAST, the data hint at gas raining back onto the galaxy rather than escaping it.

A 54-year-old man ends up dead after cops stop him for tossing an empty beer can and asking too many questions about his ID. Bodycam footage shows an officer tackle him from behind, then handcuff him unconscious before calling an ambulance; he lost his pulse en route to the hospital.

A new 80,000-square-foot depot near BNA now services Nashville's self-driving fleet, and the cars drive themselves in for repairs. It's created over 70 jobs, and Lyft says riding with Waymo costs exactly the same as riding with a human.

A "net helicity" signal from primordial gravitational waves might not mean what cosmologists think: overlooked solutions to the wave equations can carry opposite spins and muddy the reading. A new efficiency coefficient estimates how well future detectors, spanning twenty orders of magnitude in frequency, could actually catch it.
