Paleontologists have discovered the fossilised remains of one of the world's first known predators that lived in the sea around 520 million years ago. The fossils were detailed enough to show some of the brain structures.
Researchers at UCLA have found eight types of electric bacteria - bacteria that eat and excrete electrons.
The Rosetta spacecraft is approaching its target, comet 67P/Churyumov-Gerasimenko, and its latest photos reveal the comet to be, well, rubber-duckie shaped. The comet could be two bodies joined together, and this could make the planned deployment of a lander a bit complicated.

Scientists at Dartmouth College are looking at a parasite commonly found in cat poo, Toxoplasma gondii, in an attempt to develop a cancer vaccine. When infected by 'Toxo', the human body produces cytotoxic T cells that cancer would normally shut down.
