The spinorial space-time that I suggested in 1996-7 [1,2] naturally predicts a privileged space dimension for each observer. This was emphasized in some of my recent works [3,4], well before the Planck collaboration wrote on March 21-22 [5] :

Two Cosmic Microwave Background anomalous features (...) are confirmed (...). One is an asymmetry in the average temperatures on opposite hemispheres of the sky (...).

Yesterday CMS published the results of a new search for a heavy partner of the bottom quark, by looking for the decay b' -> bZ: that is, the heavy b' is sought in a so-called Flavour-Changing neutral current process. The "neutral current" is an old but still used terminology to indicate the emission of a neutral vector boson, the Z.
Despite the shutdown of the Fermilab Tevatron collider, two years ago, and the subsequent disassembling of the glorious CDF detector, the CDF Collaboration continues to produce excellent physics results using the large bounty of data they have accumulated in the course of the past 10 years.

Today you can find in the Cornell arxiv a new paper by CDF, which describes a new very interesting measurement of a property of the top quark - the particle discovered at Fermilab in 1995, the heaviest known elementary particle we know. The property measured is the lifetime of top quarks.
Note: this is the fourth, and last, part of a four-part article (see part I, part II, part III) on the five-sigma criterion for discovery claims in particle physics. If you haven't read the first three installments, the text below may or may not make much sense to you...
In 1937, Dirac made the bold conjecture that since the big bang, gravity has been weakening. The cold reception that greeted his highly speculative and numerology-based cosmology paper didn't seem to hurt him much. This was a decade after Dirac discovered the quantum relativistic equation for the electron, and his mega-stardom status could take a few hits without getting eroded significantly. Still, during the rest of his productive life, Dirac stayed away from cosmology and shrinking gravity models.
Note: this is the third part of a four-part article on the Five-Sigma criterion in particle physics. See part 1 and part 2 to make more sense of the discussion below.
In the previous installment of this longish article, I have introduced some of the issues that may affect the correct interpretation of a statistically significant effect.

A pre-emptive warning to the reader: the article below is too long to publish as a single post. I have broken it out in four installments. After reading the text below you should continue with part II, part III, and part IV (which includes a summary).

Here's a development that could have significant implications for electrochemistry, biochemistry, electrical engineering and many other fields: a Nature Materials paper is about computer simulations which find that the electrical conductivity of many materials increases with a strong electrical field in a universal way. 

Electrical conductivity is a measure of how strongly a given material conducts the flow of electric current and is generally understood in terms of Ohm's law, which states that the conductivity is independent of the magnitude of an applied electric field, i.e. the voltage per meter. This law is widely obeyed in weak applied fields, which means that most material samples can be ascribed a definite electrical resistance, measured in Ohms.

You have decided to start a graduate study in physics. Where should you apply? And how to decide which offer to take?

A diarrhea of lists attempt to rank "the world’s best universities". Mostly these lists are based on some aggregate of different metrics. Yet, for a postgraduate degree your focus should be on one and only one metric: you want to surround yourself with the best brains. If you're good, the place to hone your skills is there where you get the opportunity to learn from the best. There where you can join those that are making impact in their field of research.

What are the high-impact universities in physics?
