Dinosaur embryo find helps crack baby tyrannosaur mystery
(University of Edinburgh) They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps.

Tiny particles that seed clouds can form from trace gases over open sea
New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. The findings will improve how aerosols and clouds are represented in models that describe Earth’s climate so scientists can understand how the particles — and the processes that control them — might have affected the planet’s past and present, and make better predictions about the future.
