Viruses cause bacteria to produce pink pigments

Plants use certain colour pigments in order to convert light into energy by way of photosynthesis. They allow plants to gather light energy. This also works in a similar way for microbes, for instance cyanobacteria. The fact ...

A fossilized snake shows its true colors

Ten million years ago, a green and black snake lay coiled in the Spanish undergrowth. Once, paleontologists would have been limited to the knowledge they could glean from its colorless fossil remains, but now they know what ...

Spotted eggshells may indicate sickly mothers in great tits

The many colors and patterns of bird eggs can provide camouflage and help parents tell their own eggs apart from those of invaders, but a forthcoming study in The Auk: Ornithological Advances suggests another function for ...

Mathematical model helps show how zebrafish get their stripes

A mathematical model developed by Brown University researchers is shedding new light on how zebrafish get their iconic stripes. The model helps to demonstrate how two dynamic processes—the movement of pigment cells across ...

Lizard bling colour may act as social cue

It would come as no surprise to hear that people who live in a certain area and consume a certain diet—perhaps residents of Perth's more affluent suburbs—may present themselves in a certain way to show off to everyone ...

Pigments, organelles persist in fossil feathers

A study provides multiple lines of new evidence that pigments and the microbodies that produce them can remain evident in a dinosaur fossil. In the journal Scientific Reports, an international team of paleontologists correlates ...

Rainbow of glowing corals discovered in depths of the Red Sea

Glowing corals that display a surprising array of colours have been discovered in the deep water reefs of the Red Sea by scientists from the University of Southampton, UK, Tel Aviv University and the Interuniversity Institute ...
