Phys.org / Queasy plesiosaurs swam to shore to vomit, Jurassic fossils reveal

Plesiosaurs swam into river deltas to vomit up shells and other indigestible elements of their marine meals, suggests new research published by Cambridge University Press. The behavior resembles that of today's fur seals ...

Phys.org / The secret to a perfect crystal may be a precisely calibrated extra turn

Creating a perfect crystal sounds straightforward: Arrange identical building blocks into a repeating, orderly structure. At the microscopic scale, though, even subtle biases in how particles interact can push them in preferred ...
