Fish Size and Climate Change: Study Refutes Gill Oxygen Limitation Theory

A collaborative team of scientists led by the University of Massachusetts Amherst recently found that there is no physiological evidence supporting a leading theory-; which involves the surface area of fish gills -;as to why many fish species are "shrinking" as waters grow warmer due to climate change.

Unmasking the Energy Secrets of a Marine Bacterial Giant

Not all bacteria are created equal. Most are single-celled and tiny, a few ten-thousandths of a centimeter long. But bacteria of the Epulopiscium family are large enough to be seen with the naked eye and 1 million times the volume of their better-known cousins, E. coli.

Where Does the Light Come From? Optical Properties Allow Plants to “See” Light

An innovative study led by Professor Christian Fankhauser at UNIL and colleagues at EPFL has combined expertise in biology and engineering to reveal that a light-sensitive plant tissue uses the optical properties of the air-water interface to create a light gradient that is ‘visible’ to the plant.
