Will the $ 1,000,000 Randi Challenge Prize soon be awarded? The prize, administered by the James Randi Educational Foundation (JREF), is offered to anyone who can prove in scientifically controlled tests some form of paranormal power. So far, Randi's prize has not been claimed, but rumour has it that under supervision of the JREF an elaborate telepathy test is being conducted with shocking results.

A JREF staff member, who wishes to remain anonymous, commented on the ongoing tests with the words “I have never witnessed anything like this, this is deeply disturbing”.

"The yield of muon pairs decreased rapidly from 1 GeV to the kinematic limit of nearly 6 GeV with the exception of a curious shoulder near 3GeV. The measurement of muons was by range as determined by liquid and plastic scintillation counters interspersed with steel shielding. Each angular bin (there were 18) had four range bins, and for two muons this made a total of only 5000 mass bins into which to sort the data. Multiple scattering in the minimum of 10 feet of steel
made finer binning useless. Thus we could only note that "Indeed, in the mass region near 3.5 GeV, the observed spectrum may be reproduced by a composite of a resonance and a steeper continuum." This 1968-1969 experiment was repeated in 1974 by Aubert et al. (1974), with a
I am presently into the second week of my lessons of Subnuclear Physics for the 2nd year of specialization in Physics, and I have just finished a lesson discussing the current searches for the Higgs boson at the Tevatron collider. Since the course has a focus on experimental techniques, I found it useful today to give as an exercise the determination of an order-of-magnitude estimate of cross section limits that the CDF experiments can set on a 160 GeV Higgs boson, with the data so far analyzed. It is an exercise I worked out by heart during my walk to the Physics Department: this should tell you it is not of overpowering difficulty.
Based upon some recent statements by the DOE, the commitment to building a muon collider in this country may be more tangible:

Here is a conceptual layout:




These days the Higgs boson search is a bit over-hyped, with the impending competition between Tevatron and LHC on the discovery of the fabled boson making headlines every time there is a new, even minor, update in the results of the CDF and D0 experiment. But the hunt is on for many other, maybe even more interesting, rare processes.
Researchers using measurements of the cosmic microwave background - a faintly glowing relic of the hot, dense, young universe - say their results provide support for the cosmological model of the universe - a prediction that dark matter and dark energy make up 95% of everything in existence while ordinary matter makes up just 5%. 

Writing in The Astrophysical Journal, researchers on the QUaD telescope project have released detailed maps of the cosmic microwave background (CMB); they focused their measurements on variations in the CMB's temperature and polarization to learn about the distribution of matter in the early universe.
A Sunday morning browsing through preprints recently posted in the Cornell Arxiv revealed interesting reading material. If you have a couple of hours to kill next week, why not having a look at the following papers ? It will definitely hurt you less than spending the time on your WII or watching Jerry Springer.
My statistics page depressingly shows that a large fraction of readers who visit this site do so for an average of 30 seconds. Maybe they were looking for something different, or maybe they do not like the content offered here. In any case, I have decided that my long, detailed articles about particle physics are not exactly meeting the demand of the audience. I am not going to change my writing style because of that, of course, but I will try to also offer some thirty-seconds physics bits here, every once in a while. So let me make a dry run, using a recent result by the CDF collaboration. The clock may start.
NASA's Fermi Gamma Ray Space Telescope has captured more than one thousand discrete sources of gamma rays in its first year, including a measurement that provided experimental evidence about the very structure of space and time, unified as space-time in Einstein's theories.
You read right his "mad" idea is simply that electromagnetic fields effect the formation and evolution of cyclones.  What they proposed and measured in the paper, "
