Nearly three-fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese ...

Earth's oceans could one day turn purple. Nearly three fourths of Earth is covered by oceans, making the planet look like a ...

In the waters off Iwo Jima, a volcanic island in Japan’s Satsuma archipelago, the sea has a distinct green tint. It’s not just a trick of the light — it’s caused by microscopic particles of oxidized ...

Engineered bacteria can sense environmental ... In each case, the pigment's production was tied to a genetic circuit that responds to specific stimuli, such as the presence of nearby bacterial cells.

Bacteria can be engineered to sense a variety of molecules, such as pollutants or soil nutrients. In most cases, however, these signals can only be detected by looking at the cells under a microscope ...

This makes it easier to program the bacteria. For one soil-based bacterium, Pseudomonas putida, the researchers used a molecule called biliverdin, which is a green pigment formed when blood breaks ...

Inspired by sea sponges, researchers created living micro-lenses from bacteria that may improve medical and industrial ...
