I follow MIT’s Knight Science Journalism Tracker (KSJT) as a way to keep up on science news making headlines. The writers there aggregate science coverage with an added bonus of a brief review of the (more-or-less) mainstream articles.
In this 28 June 2012 post, author Charlie Petit discusses news about the latest cutting-edge physics from Brookhaven National Laboratory in New York State. Physicists there used the Relativistic Heavy Ion Collider to crash gold nuclei together and create the fiercest heat since the Big Bang: 7.2 trillion degrees Fahrenheit. The resulting visual is highlighted in the KSJT post.
