Phys.org / Global food shock model reveals self-sufficiency alone may not prevent crises

Global food systems are fragile. Recent shocks such as the closure of the Strait of Hormuz and the Russian invasion of Ukraine have raised prices and exacerbated food insecurity. Governments are increasingly trying to shield ...

Phys.org / New MRI sensors detect target molecules in the brain and body with high sensitivity

When doctors and scientists want to see inside a body, magnetic resonance imaging (MRI) is a powerful tool. MRI can noninvasively capture detailed images of the body's muscles, organs, and bones. It can monitor blood flow ...
