New, more sensitive sensor for evaluating drug safety
A new technique for evaluating drug safety is designed to be affordable and can detect stress on cells at earlier stages than conventional methods.

Governments need to do more to support older people's transport needs, study suggests
European governments could be doing more to develop transport policies that ensure those over the age of 65 remain active and mobile, according to a new study led by the University of Plymouth with the Erfurt University of Applied Sciences.

Molecular biologists discover an active role of membrane lipids in health and disease
Cells produce insulin, for example, or generate antibodies. To perform these functions, cells need to produce large quantities of proteins.

Why is conducting research in some countries so difficult?
Low- and middle-income countries such as Brazil face a lack of epidemiological data, and one of the key priorities for researchers is developing high-quality surveys.

New model for bimolecular reactions in nanoreactors
Theoretical physicists have devised a mathematical model of two different molecules reacting within so called nanoreactors that act as catalysts.
