Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
(PhysOrg.com) -- By precisely shaking a container of shallow water, researchers have observed wave behavior that has never been seen before. In a new study, Jean Rajchenbach, Alphonse Leroux, and Didier Clamond of the University ...
Magnetotactic bacteria, which can align with the Earth's magnetic field, have been discovered in a new location. Previously observed on land and in shallow water, analysis of a hydrothermal vent has proven that they can also ...

(Phys.org) —A team of researchers with members from Germany and Egypt has found that red fluorescence as found in many species of fish appears to be for visual purposes, rather than as a UV protection mechanism. In their ...
(PhysOrg.com) -- Fossilized ammonites found with bite marks in similar places on their shells suggest they were eaten by other cephalopods such as beaked squid, according to new research published in the Proceedings of the ...
