Among the most important physics headlines this week we saw a discovery of a new mathematical tool, which will help probing the universe, reports of hints of dark matter and the update on the upgrade of the LHC. So let’s take a closer look at these interesting discoveries in another edition of the “Physics News of the Week”.

1) Upgraded LHC — Gates to New Physics (April 2)
After the great discovery of the Higg’s boson LHC has been undergoing major updates, which are planned to double to power of the already most powerful particle collider in the world. As reported by the BBC News, scientists are expecting new particles which will lead to a more complete understanding of particle physics and other theories. As the leader of the Atlas experiment, Dr. Pippa Wells, commented, “The past two years have been the most exciting in my time as a particle physicist. People are absolutely fired up. They’ve made one new discovery (the Higgs) and they want to make more discoveries with the new high energies that the upgrade will give us. We could find a new realm of particle physics.” Read the full update here.
More discoveries are expected from LHC
2) Hints of Dark Matter (April 3)
Dark matter is one of the greatest unsolved problem of Astrophysics, thus there is no surprise that a $2 billion cosmic ray detector was put up to the International Space Station a few years ago. However, only recently, the first traces of the mysterious dark matter came back. The first evidence that came in Wednesday showed tantalizing cosmic footprints that seem to have been left by dark matter. However, the evidence isn’t enough to declare the case closed. The footprints could have come from another, more conventional suspect: a pulsar, or a rotating, radiation-emitting star. According to Sam Ting a more definite answer is expected in a matter of months. Read the full report here.
3) A New Method to Probe the Universe (April 4)
One of the methods to detect a shape of an object is using sound — each objects emits sound, which is characteristic to its shape. So, for instance, if you tap a vase with a spoon, the emitted sound could be used to investigate the shape of it. According to a new paper at Physical Review Letters, a similar technique could be used to study the shape of space time itself by studying quantum fluctuations. The importance of the discovery lies in the fact that it links the two major fields of physics — quantum theory and general relativity. Read the full article here.
