Mussel's calcitic shell growth adheres to physical laws familiar from processes used to optimise steel

Mussels are veritable masters of biomineralisation. They make hard, robust composite materials from simple substances in order to build their shells. Furthermore, the shell material itself is produced in an exemplary way. ...

First 'heavy mouse' leads to first lab-grown tissue mapped from atomic life

Scientists have created a 'heavy' mouse, the world's first animal enriched with heavy but non-radioactive isotopes - enabling them to capture in unprecedented detail the molecular structure of natural tissue by reading the ...

Learning from biology to create new materials

In nature, some organisms create their own mineralized body parts—such as bone, teeth and shells—from sources they find readily available in their environment. Certain sea creatures, for example, construct their shells ...

Mushrooms and earthworms work as 'silviculture'

A model, developed by a research group of the School of Forestry at the Technical University of Madrid (UPM), has shown how some types of mushrooms (such as truffles, boletus or chanterelles) associated with earthworms can ...
