The CDF collaboration sent to the preprint arxiv a new paper a few days ago. In it, they report on a measurement of the mass difference of top and anti-top quarks. The result would not be worth discussing in detail, if it did not show a 2-sigma discrepancy which might be the first hint of a CPT violation. So let me discuss it here.
My blogging output here is scarce this week, because I am spending my time at the NEUTEL 2011 conference in Venice. I am producing some posts summarizing the talks I hear at the conference, together with a few colleagues. Our blog there will be short-lived, but already collects about 1000 views a day, growing by the day. Here is a selection of recent posts you can find -I only list here those published today or yesterday:

99942Apophis A asteroid which if it were to hit earth would hit off the coast of California and do damage similar to the Earthquake. A 9.0 magnitude earthquake is equal to about 450 megatons of TNT being set off underground.  Due to the situation at the Daiichi nuclear plant near in Sendai Japan there is much talk of how nuclear plants should not be built in earthquake zones.
What is a BLEVE?

A BLEVE is a Boiling-Liquid Expanding-Vapor Explosion.

It is fairly common knowledge that removing the radiator cap of a vehicle with a hot engine will cause the ejection of boiling water.

The NEUTEL 2011 conference started today in Venice. Many experiments in neutrino physics will be reporting new results there, and the interest is of course high in the community. Along with a few vailant physicists from my university, I will be blogging form the site, trying to cover all the important new information as well as some other information in general. So please visit the NEUTEL11 blog to learn the latest news on neutrino physics... Already there is a report on a general overview of neutrino oscillations by Art McDonald, among with additional posts on HEP results.
Researchers say they have ruled  the cosmic bubble theory, an alternate theory on the nature of dark energy, after recalculating the expansion rate of the universe to unprecedented accuracy.

The universe appears to be expanding at an increasing rate and some believe that is because the universe is filled with a dark energy that works in the opposite way of gravity. One alternative to that hypothesis is that an enormous bubble of relatively empty space eight billion light-years across surrounds our galactic neighborhood. If we lived near the center of this void, observations of galaxies being pushed away from each other at accelerating speeds would be an illusion.
Third graders enjoy clay and pipe cleaners. It might sound cruel to teach them graduate level graph theory most math Ph.D.’s have not seen, but I might get away with it if I uses the right craft supplies. Tell kids spinach is good for them. Children are right to skeptical, as I expect of my reader.

... Not really.

What startled me most was that a colleague of mine at the University of Padova even sent a message to my departments' mailing list, saying that the new result is very important. But it clearly isn't! In fact, the exclusion at 95% CL in the range of Higgs boson masses that CDF and DZERO could put together from the analysis of additional data is almost exactly the same as the one that they published last Summer.

But maybe I should make a step back and explain the matter from the start, to let you judge by yourself the relevance of the new Tevatron bounds on the rate of Higgs boson production in proton-antiproton collisions.

CDF and DZERO are analyzing the proton-antiproton collisions at 2 TeV that the Tevatron collider is producing since 2001.

Neutrino phyisics may be boring, as Jester claims in a post today at the NEUTEL11 blog, or exciting, as many others are ready to testify. And since Jester talks about exciting new results ready to be submitted by the XENON100 collaboration, I would bet you will concur with the latter.
I define the fringe as anyone trying to make a contribution to a field where they are not employed or do not have a degree in the subject.  I happen to be a fringe physicist because my degrees from MIT were in Biology and Chemical Engineering.  My current job is in software with no connection what-so-ever with physics.
