Researchers have determined an epic expansion of a plant's mitochondrial genome via of horizontal gene transfer, acquiring six genome equivalents of foreign DNA. It is the first time that an organelle has captured entire "foreign" genomes, those from other organisms, and the first description of a...

Scientists at Tübingen’s Institute of Astronomy and Astrophysics (IAAT) have laid the groundwork for the next big European Space Agency mission.
