Oldest Pigments Found in Ancient Fossils Researchers have extracted colourful organic molecules from the fossilized remains of 350-million-year-old sea creatures. The orange and yellow pigments may provide a new way of tracking the evolutionary history of the ancient crinoids, or sea lilies, which still swim around ocean reefs today. |

Ancient Bird Fossil Makes a Splash Recent expeditions in a remote area of China have unearthed unusually well-preserved fossils of an ancient bird that lived between 105 million and 115 million years ago. The fossils of the surprisingly modern-looking bird suggest that today's birds may have originated from an aquatic ancestor. |

Branchy Molecules Make Precise Pores Researchers have found a way to coax a material containing microscopic pores to assemble from two very different types of molecules. The material could be used as packaging material for microscopic electronics, to store gases, and to deliver tiny amounts of drugs to very specific places. |

An African puzzle piece The time period from 32 to 24 million years ago has largely been a black hole for paleontologists studying East Africa's animals. Newly discovered large vertebrate fossils from Ethiopia, however, are providing evidence that not only was there a thriving and diverse population, but also that it continued long after. |
