Most people have collected shells at the beach. Some have even started a shell collection. But few people realise these shells are a unique genetic resource that scientists are only beginning to tap ...

Shell colour variation in mollusks is a multifaceted trait governed by complex genetic mechanisms that orchestrate pigment biosynthesis, tissue differentiation and biomineralisation. Studies indicate ...

A collection of fossil shells from marine snails and clams is challenging a theory that says the world's deadliest mass extinction was accompanied by severe ocean acidification. The study is the first ...
