Black holes help stars to form and evolutionary adaptation to roads

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 - The center of just about every galaxy is thought to host a black hole, some with masses of thousands of millions of suns and consequently strong gravitational pulls that disrupt material around them. They had been thought to hinder the birth of stars, but now an international team of astronomers studying the nearby galaxy Centaurus A has found quite the opposite: a black hole that seems to be helping stars to form. See article.
g Abodes - Using 10 years of data from atmospheric and oceanic data, scientists are providing new information about the energy balance of Earth. See article.
g Life - Spotted salamanders exposed to contaminated roadside ponds are adapting to their toxic environments, according to a Yale paper in Scientific Reports. This study provides the first documented evidence that a vertebrate has adapted to the negative effects of roads apparently by evolving rapidly. See article.
