Anonymous now has more credibility than all four big US cable news channels and the big newspapers combined.  This is due to the fact that while they and their sources are …anonymous.. they manage to find verifiable information.  This claim is different.   IF this is true there are only TWO ways NASA could have found proof of extraterrestrial life.  SETI has intercepted a convincingly strong source of intelligently engineered radio from a known habitable zone Kepler planet.

Lab-grown cartilage grown shows similar mechanical and chemical properties to the natural articular cartilage which allows our joints to move smoothly, according to a new study in Nature Materials

A team biomedical engineers from University of California, Davis, created the lab-grown tissue similar to natural cartilage by giving it a bit of a stretch, growing it under tension but without a supporting scaffold. Their results show similar mechanical and biochemical properties to natural articular cartilage. 

There is a very simple high school homework exercise question that I have kept with me for 30 or so years because of its deep relevance for the understanding of fundamental physics. It teaches about the nature of quantum uncertainty, but sadly also about how terribly wrong textbooks can be, how nonsense makes it into print and is taught to millions as the wisdom of science, although about one minute playing with a guitar, or ten minutes of critical thought, should have told the author, or some teacher, or somebody for crying out loud. Now as I am teaching and writing a book on fundamental physics for lay people as well as applied and social scientists, it shall finally be resolved properly.

The question is simple; I rephrased it a little from the original:
A new study has found that found that flavonoid levels and antioxidant activity in organic onions are higher than in conventional onions, which disputes a meta-analysis which debunked claims by discredited industry-funded economist Dr. Chuck Benbrook and colleagues who asserted that the organic process led to higher nutritional quality.

The new paper did find just that, though the benefit may be meaningless. Antioxidants and flavonoids have yet to show any measurable health benefit, but the demographic that buys organic food is more likely to buy those kinds of supplements touting benefits of phytochemicals. 
Formaldehyde sounds scary because it is for dead bodies. But it is also produced in our natural cellular respiration. Clearly "the dose makes the embalming fluid" but groups who want to scare people about diet soda whisper about its presence. And it is present, in levels that will be carcinogenic if you drink 7,000 sodas per day. More recently its presence in nicotine vaping liquid was being touted.

A new review of my book, "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab", has appeared on the June issue of "Physics World". It is authored by Gavin Hesketh, a lecturer at University College London, and you can read it here.
In the evening of May 30 a giant fireball lit up the skies south of Venice, Italy. The object, which was traveling very slowly along a south-north trajectory, was captured by three video stations in the area, plus observed by countless bystanders and recorded in pictures. The video data allowed to precisely measure the trajectory, which made it clear that the rock was headed straight toward the Venice metropolitan area, and that it would have landed there if it had not disintegrated in flight.

This article continues the series of postings in this blog on the results of artistic work by high-school students of three schools in Venice (out of five who took part initially) that participate in a contest and exposition connected to the initiative "Art and Science across Italy", an initiative of the network CREATIONS, funded by the Horizon 2020 programme of the EU.

Today I gave a seminar at the Physics Department of the University of Helsinki, to talk of "Controversial Phenomena in Collider Data and the 5-Sigma Criterion in HEP", invited by Juska Pekkanen and Mikko Voutilanen, two CMS colleagues. 
The seminar is more or less the same I have given several times in the past year around Europe and the US. It contains some statistics, some HEP history, and some material taken from my recent book, "Anomaly!".
