Key step in evolution of life replicated and could the Death Star really destroy a planet?

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Scientists have long struggled to detect the dim dwarf galaxies that orbit our own galaxy. So it came as a surprise when a team of astronomers using Keck II telescope's adaptive optics has announced the discovery of a dwarf galaxy halfway across the universe. See article.
g Abodes - Research shows that greenhouse gases are disrupting Earth's glaciation. Heat trapped in the atmosphere could delay the next ice age by tens of thousands of years. See article.
g Life - Biologists have long wondered how sing-celled organisms on the Earth began forming multicellular clusters some 500 million years ago. Now, scientists have replicated this key step in the evolution of life. See article.
g Cosmicus - Researchers pose the question, could a small moon-sized battle station generate enough energy to destroy an Earth-sized planet? See article.
