Steve Nerlich from the Cheap Astronomy podcast gives us an update on the roller-coaster life of the ISEE-3 space probe. It was alive, then it died, then it was resurrected then it seemed dead but now it may be still alive again! 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. A well-preserved, complete fossil skeleton of the largest known microraptorine - a flying non-avian dinosaur - has been found in China. Called Changyuraptor yangi, the dinosaur was about 1
