Price for orbiting too close to one’s star and detecting chiral molecules

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 - Yes, M-type stars do evolve, just not in the classical sense that we are used to with solar-type stars. See article.
g Abodes - Astronomers have determined that giant exoplanets orbiting close to their stars could lose so much of their mass that only their cores remain. The smallest exoplanet discovered so far, which is less than twice the size of Earth, may be an example of this phenomenon. The study could have implications in the search for habitable worlds around distant stars. See article.
g Life - Scientists have developed an instrument for detecting polarized light after it reflects off of chiral molecules. Living organisms contain many chiral molecules, and the new technology could be useful in searching for life beyond our planet. See article.
g Cosmicus - The White Sands Missile Range in New Mexico is testing a new "laser beam." See article.
