Did scientists finally detect dark matter in South Dakota?

No confirmed detection has been made. The LUX-ZEPLIN experiment recorded one unusual particle interaction that could have been caused by dark matter, but other explanations have not been ruled out.

Berkeley Lab says the event is difficult to explain using known background processes, but the result reached 2.6 sigma rather than the 5-sigma threshold normally required for a discovery. Reuters independently reports that the researchers explicitly stopped short of claiming detection.

The event is scientifically significant because it gives researchers a specific signal to test with more data. For now, calling it the first direct detection of dark matter goes beyond the available evidence.
