Artificial intelligence (AI) learning machines can be trained to solve problems and puzzles on their own instead of using rules that we made for them. But often, researchers do not know what rules the machines make for themselves. ...

Urban traffic noise causes song learning deficits in birds  

Traffic noise leads to inaccuracies and delays in the development of song learning in young birds. They also suffer from a suppressed immune system, which is an indicator of chronic stress. A new study by researchers of the ...

Quantum machine learning hits a limit

A new theorem from the field of quantum machine learning has poked a major hole in the accepted understanding about information scrambling.

EPA revokes Trump-era policy that loosened clean-air rules
