I posted a very short rough paper here a while back.  "Dark Matter and Energy as Particles and Fields of Unobserved Scalar and Vector Fields (PDF) (rev2).." Since then certain comments and supposed extremely elementary errors have been pointed out.  The following is a referee report from a well respected journal.  These are (mostly) valid critiques stated in a polite and professional manner.  None of the things which were pointed out by bloggers are here, which were for the most part so elementary that if true there would not even have been a peer review. 
A new public document has been made available on the CMS public web page yesterday morning. It reports on a study of the reach of the CMS detector, with data collectable in 2010, for a signal of large extra dimensions, using the very distinctive signature of a high-energy jet recoiling against -well, recoiling against nothing; or better, something which left our world and entered into another dimension of space.
From August 30th to September 2nd I will attend the 29th edition of "Physics in Collision" in Kobe, Japan, to hear a few interesting talks and to present a poster on behalf of CMS, about the search for the Standard Model Higgs boson.

Posters are what they sound like -big, illustrated sheets of paper. Many conferences have a "poster session" in which authors of the posters stand in front of their creation and discuss the details with colleagues and answer questions about the contents. Before the poster session, each poster is usually presented by the author with a short oral memo -five minutes each at PIC.
The Arxiv is an online repository of scientific papers in physics, astronomy, maths, cosmology, computer science, and a few other topics, where papers due to be published on scientific journals are submitted by the authors, and become quickly accessible for free to anybody before the peer-review process ran by the journals is over and they get printed there.
Patrick Draper is a graduate student in physics at the University of Chicago and Argonne National Lab. He is a native of Illinois and lives in Hyde Park, Chicago with his wife Karen and parrot Felix, to whom he is grateful for their love, patience, and correcting his sign errors. He is a supporter of the international effort to put a muon collider on Mars, and is waiting for NASA to return his phone calls.
I asked Patrick to write here about his studies on the discovery reach for a MSSM Higgs boson after I saw his paper on the arxiv a month ago, and am now glad I did. Enjoy!

Just what would time travel look like?  This question was posed to me by a movie director in L.A..  It turns out there are three parts to this question-- what physics suggests, what movies have done in the past, and what looks good.

The last is up to her and her special effects staff.  The middle one-- Hollywood traditions for time travel-- are worth examining to scope out possibilities.  I'll then conclude with what I think physics suggests is most likely.

Were I to invent categories for movie time travel effects, I'd create the following:

  1.   techno with lots of lights and whooshing (ala 2001, though that wasn't time travel)

  2.   high speed vehicle (similar to techno, but with speed lines)

Physicists at the National Institute of Standards and Technology (NIST) have devised a viable way to manipulate a single 'bit' in a quantum processor without disturbing the information stored in its neighbors, using polarized light to create "effective" magnetic fields.

A great challenge in creating a working quantum computer is maintaining control over the carriers of information, the "switches" in a quantum processor while isolating them from the environment. These quantum bits, or "qubits," have the uncanny ability to exist in both "on" and "off" positions simultaneously, giving quantum computers the power to solve problems conventional computers find intractable – such as breaking complex cryptographic codes.
Unfortunately I was right: at least in predicting that the INFN exam dubbed "R5" would not go deserted. The R5 exam, which in exchange for a stressful pair of written tests (which I am trying to get a hold of, to report on it here) guaranteed nothing that the participants did not have beforehand  -a certification of readiness for a temporary position within INFN, which the institute cannot however offer, being short of cash-, saw the participation of 178 candidates among the about 350 who had submitted their application a couple of months ago. Barely more than half: this is a victory, since the participation is sufficient to grant value to the results.

The 2009 World Conference on Science Journalism took place last week in heat-wave-struck London, at the convenient location of Westminster Central Hall (see below). More than 900 delegates got together from 90 countries to discuss the future of science journalism, understand the challenges the field is facing, and finding strategies to face them. An impressive event, excellently organized.
