How CERN’s discovery of exotic particles may affect astrophysic
You may have heard that CERN announced the discovery of a strange particle known as Z(4430). A paper summarizing the results has been published on the physics arxiv, which is a repository for preprint (not yet peer reviewed) physics papers. The new particle is about 4 times more massive than a proton, has a negative charge, and appears to be a theoretical particle known as a tetraquark. The results are still young, but if this discovery holds up it could have implications for our understanding of neutron stars.
The building blocks of matter are made of leptons (such as the electron and neutrinos) and quarks (which make up protons, neutrons, and other particles). Quarks are very different from other particles in that they have an electric charge that is 1/3 or 2/3 that of the electron and proton. They also possess a different kind of “charge” known as color. Just as electric charges interact through an electromagnetic force, color charges interact through the strong nuclear force. It is the color charge of quarks that works to hold the nuclei of atoms together. Color charge is much more complex than electric charge. With electric charge there is simply positive (+) and its opposite, negative (-). With color, there are three types (red, green, and blue) and their opposites (anti-red, anti-green, and anti-blue).

Research linked to stress in mice confirms blood-brain comparison is valid

Johns Hopkins researchers say they have confirmed suspicions that DNA modifications found in the blood of mice exposed to high levels of stress hormone — and showing signs of anxiety — are directly related to…

The Great Andromeda Galaxy, M31

The Andromeda Galaxy is a spiral galaxy and it the closest large galaxy to the milky way (this is not including dwarf galaxies). It is approximately 2.5 million light-years away in the constellation Andromeda and is listed as the 31st object in Messier’s catalog of large night-sky objects.

Andromeda is one of the easiest objects to spot in the night sky. It can be seen on a clear night with the unaided eye as a faint smudge of light about 3 times the apparent length of the moon. This makes the Galaxy a great viewing/imaging target if you have a pair of binoculars or a telescope.

Like our milky way galaxy, the Andromeda galaxy has smaller satellite galaxy, known as dwarf galaxies, that orbit it. One of these dwarf galaxies can be seen in the above images as a small smudge below Andromeda’s galactic disk.

The top image shows a wide field view of the Andromeda Galaxy. The next two images show wide field views of the galaxy in infrared and ultraviolet light and the last two are infrared and ultraviolet images taken recently by the Spitzer space telescope.
