There is a widespread misconception which is repeated often these days in the aftermath of the OPERA collaboration’s confirmation of faster than light neutrinos. The misconception is easily stated:

“Tachyons, if they actually exist, have imaginary mass, … blah blah blah … therefore OPERA is wrong!”

Let us explain what this means in layman’s terms, then see how this argument fails, and afterward discuss that it is one example for a common logical fallacy that basically underpins all the arguments against the OPERA results that we encountered recently.

I am sure it is old news to most if not all of Science 2.0's readers that NASA recruited Vint Cerf to help adapt Internet technology to space mission communications in 2000; and that they successfully tested a new protocol in 2008. I have no doubt that the engineers can put together a pretty reliable interplanetary network.

As I review journals and articles dealing with clinical trials I have found the most glaring problem that, I am sure, no one will address. Namely; quoting data "from the book."

So, what am I talking about? Specifically about researchers, I mean the real researchers, not "re-inventing the wheel" but being satisfied just pulling the data from a "trusted" source and running with it.

Best explanation I can give uses an example. In a clinical trial looking at the impact of ascorbic acid on tumor growth, the researching group, (medical team), noted the milligrams of dose given, adjustment for weight&sex, and then ran the trial.

For you today here is a test of whether you shoud trust your intuition when confronted with an apparently simple problem. Incidentally, this article is the answer to the "Guess The Plot" riddle I posted a few days ago here.

Suppose you are given two measurements of the same physical quantity. Make it something easy to visualize, such as the length of a stick. They tell you that when measured with method 1 the result was x1=10 cm, with a estimated uncertainty s1=0.1 cm, and when measured with method 2 the result was x2=11 cm, with estimated uncertainty s2=0.5cm. Here is a question for you today: What is your best guess of the length of the stick ?

Sex helps in multiple ways, it seems.  New research presented at The Gerontological Society of America's meeting, based on 2004 General Social Surveys, found that the more often older married individuals engage in sexual activity, the more likely they are to be happy with their lives and marriages.

Based on the survey responses of 238 married individuals age 65 years or older, the research showed that frequency of sexual activity was a significant predictor of both general and marital happiness. The association even remained after accounting for factors such as age, gender, health status, and satisfaction with financial situation.

Researchers have developed what they are billing as the world’s lightest material. With a density of 0.9 mg/cc, it is about one hundred times lighter than Styrofoam™. 

The new material redefines the limits of lightweight materials because of its unique “micro-lattice” cellular architecture, they say - consists of 99.99 percent air by designing the 0.01 percent solid at the nanometer, micron and millimeter scales.  The material’s architecture allows unprecedented mechanical behavior for a metal, including complete recovery from compression exceeding 50 percent strain and extraordinarily high energy absorption.

In the first part of this look at magma chambers, I talked about some of the processes that dominate what goes on beneath an active volcano.  The twin actions of fractionation and assimilation were what preoccupied the early researchers, however more recently we've realised things are a little more complicated than that.  In this part I want to take a closer look at some of those intricacies.

Totally overshadowed by the news of the new Opera measurement of neutrino speeds, yesterday CERN officially released the combined result of ATLAS and CMS searches for the Higgs boson. The news has been given already in two prominent particle physics blogs (Resonaances and Not Even Wrong), so I think I am not obliged to do anything more than point you to those, who cover the matter quite accurately.
