Curiosity and other updates

Summary: Curiosity has discovered that most of Mars's atmosphere has since departed into space. Scientists discovered this by looking at the chemical of argon. Argon reacts with very little so the only way the lighter isotopes will have given way to a majority of the heavier isotopes is by escaping into outer space. The article does not comment on what this means when trying to determine whether or not Mars ever had flowing water other than to say that scientists are still split.

Summary: The Alpha Magnetic Spectrometer (AMS) in the sky has made some observations that may give additional evidence to dark matter. Stay tuned.

Summary: The LHC is being upgraded so that is can find new particles. Not too much info at this moment.

Cosmic ray origin confirmed

Summary: The Fermi telescope has confirmed that cosmic rays originate from the star explosions known as supernovae. They actually get accelerated toward Earth not by the explosion itself, but rather by the shock wave created after the explosion. (That's the part that looks beautiful in images!)
Scientists determined this by looking at characteristic particle decays. They know that pions decay into gamma rays which then travel toward Earth. Studying the gamma rays are ideal since they are not affected by magnetic fields and thus will point directly back to their source after being detected by Fermi.
