New diagnostic criteria shine light on early dementia mimics
4dExperts estimate up to one third of people attending specialist memory clinics in the UK could have a condition that is commonly mistaken for early dementia.

A new role for a well-known molecule as a plant hormone
4dResearchers have discovered a new role for a well-known plant molecule, providing the first clear example of ACC acting as a likely plant hormone.

Seeing a fluid behaving like a solid
4dResearchers using a high-speed camera have captured the moments a fluid reacts like a solid, through a new method of fluid observation under pressurized conditions.
