Japan's first comprehensive AI law puts "promotion" rather than regulation at its core. A new study in Risk Sciences traces this choice to Japan's distinctive social conditions – low AI adoption, low public trust, an ageing population and ageing corporate IT systems – and finds that promotional measures have boosted individual use and corporate trials, but have not yet driven deep integration of AI inside organisations.

Scientists have found a way to use defects in crystals to engineer stronger materials, according to a new study. 

A new Caltech-led paper demonstrates that an AI program—specifically a type of neural network called a recurrent neural operator (RNO)—can be used to predict when tipping points occur in simple models, including models of a climate-change system and simulations of turbulent airflow over a plane's wing. 

In Philadelphia, and many urban areas across the country with sewer systems dating back to the 1800s, more frequent flooding is posing a threat not only to people and property, but also to surrounding ecosystems. In these areas stormwater and sewage drain into the same pipes and when flooding occurs they are designed to spill into nearby waterways, rather than inundating streets. Researchers at Drexel University, in collaboration with the Philadelphia Water Department, are looking at the long-term water quality impact of these events — called combined sewer overflows — to understand what steps could be taken to mitigate their negative effects.
