Planet formation a natural by-product of star formation and aliens beaming signals at one another

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 - A new study has confirmed that planet formation is a natural by-product of star formation, even around stars that are much larger than the Sun. However, it is not likely that planets around large stars could support complex forms of life. See article.
g Abodes - Our knowledge of Titan has improved considerably over the last five years. Before that, Saturn's largest satellite had only been hastily approached by a handful of space probes. See article.
g Life - By studying how alligators breathe, scientists have drawn new connections between the reptiles and modern birds. Their breathing method may have helped the dinosaurs' ancestors dominate the planet after one of Earth's worst mass extinctions. See article.
g Message - However, since the invention of the radio, humans have been broadcasting signals into outer space. Other civilizations in our galaxy might be doing the same. They might even be deliberately sending out signals to find other civilizations. Someone out there may even be beaming a signal directly at the Earth. See article.
g Cosmicus - A group of 13 scientists hoping to perform experiments on suborbital spaceships took a dizzying spin in a centrifuge this week in the first-ever commercial training session targeted at civilian researchers. See article.
