Genomic evidence of rapid adaptation of invasive Burmese pythons in Florida  

New researchers set out to determine whether pythons could have adapted to an extreme Florida freeze event in 2010. They generated data for dozens of samples before and after the freeze event. By scanning regions of the Burmese python genome, they identified parts of the genome that changed significantly between the two time periods, providing clear evidence of evolution occurring over a very short time scale in this population.

Using Gamma Rays, Scientists Map Out 21 New Constellations  

Gamma-Ray Sky For countless years, humans have gazed up at the sky and made sense of the stars by finding shapes in them — constellations of heroes, animals, and well-worn tales. Now, to celebrate the 10th mission year of NASA's Fermi Gamma-ray Space Telescope, scientists have used the telescope to develop a new set of constellations that correspond with gamma-ray emissions. Gamma rays are the most powerful in the electromagnetic spectrum, and they're typically only produced by very po...

In a First, Astronomers Find a Blazar That Cycles Every Two Years  

Blazar Brightness After 10 years of observations, scientists have confirmed a two-year cycle in the gamma-ray brightness of a blazar, or a galaxy with supermassive black holes that consume mass and produce high-energy jets as a result. Blazars are the most energetic and luminous objects that we have identified so far in the known universe. "This is the first time that a gamma-ray period has been confirmed in an active galaxy," Stefano Ciprini, a researcher at the INFN Tor Vergata divis...

The Drake Equation: What Are the Odds That Aliens Exist?  

The Drake equation is one of astronomy's most famous attempts to answer the question: Are we alone? It asks not just about any life, but the top shelf stuff: intelligent life with the ability to communicate with beings outside their planet. Microbes or floating sentient clouds don't make the cut. We want aliens that will talk to us. To be clear, this means there could be life out there in the universe that the Drake equation would discount. But in terms of knowing how likely we are to re...
