Rare mineral discovered in plants for first time

Scientists at Sainsbury Laboratory Cambridge University have found that the mineral vaterite, a form (polymorph) of calcium carbonate, is a dominant component of the protective silvery-white crust that forms on the leaves ...

Sea butterflies repair shell damage from ocean acidification

A new study of tiny marine snails called sea butterflies shows the great lengths these animals go to repair damage caused by ocean acidification. The paper, led by researchers at British Antarctic Survey, is published this ...

Plant defense following the iron-maiden principle

Calcium phosphate is a typical component of teeth and bones. It has recently been shown that plants of the rock nettle family also use this very hard mineral in their "teeth" to defend themselves against their animal enemies. ...

Watertight capsules for target drug delivery

Researchers from Tomsk Polytechnic University and Queen Mary's University of London have developed smart capsules that deliver water-soluble compounds to a certain part of the body. Two-micron capsules have watertight shells ...

Dentistry study pinpoints role of proteins that produce pearls

Pearls are among nature's most beautiful creations, and have been treasured for countless centuries. Beneath one's iridescent surface lies a tough and resilient structure made of intricately arranged tiles of calcium carbonate ...

Marine snails know how to budget their housing costs
