They record calcium activity in neurons. Calcium is a marker of neuronal activity (although the dynamics are slower than electrical ones). Calcium recording in the nematode is difficult, because the neurons are small, and the spread of calcium is very broad. The method is impressive and a great breakthrough. However...

1. A brain is a center of the nervous system. It's not strictly correct to speak of brains of nematodes. They don't have this separation of their nervous system. In the article they write of the anterior nervous system of the nematode, and say that their technique could be applied to brains of other animals. 2. The short clip is not a recording of all neurons. It's 70% of the neurons contained in the head ganglia.

Some people here speak of the mapping of the network. This was already done in 1986. The nematode is highly stereotypic. It's known what neurons there are (they all have acronyms), how many, and what they are connected to. The weight of these connections is not clear yet however. What is not clear are the associated neurotransmitters to these synapses and the strength of synapses. This determines how strongly neurons modulate each other and if the modulation is excitatory or inhibitory.

With some caveats in place, the potential of the recordings based on this technique is to help to get to the connection strengths, and to a functional connection diagram that then can potentially be used for predicting the animals behavior.

Linked with means related to. There's no causation implied, sorry. Xkcd's comic had a lot of success and since then it's a knee jerk reaction to accuse people of confusing the two terms, but it often pays off to count to three.

Ron Paul: "Evolution is a theory and I don't accept it". For me he's out.

Well... you are right, partly, I think, in pointing out that there's still a lot of bullshit around. However, it is known that culture is, in fact, a very powerful mechanism (I think you can come up yourself with a bunch of examples). It is sometimes quite difficult to distinguish between cultural and biological factors, however, what is interesting in this study, I think, is that did an international comparison of boys vs girls' math scores and compared these to different socio-economic factors. I have to admit, I didn't take the time to read all of it, but they actually show a pretty convincing scatter plot between gender equality index and girls' math performance relative to boys'. If you don't look at anything else, look at that plot.

What about other factors that are different between genders?

I don't know about relative levels of aggression, I guess it is pretty much established that aggression level is at least partly determined by testosterone level and related hormones. An elevated level of aggression (btw, Lorenz defines aggression as social dominance behavior) would affect professional (or leadership) ambition, but I would guess that a lot of that (missing ambition) has to do with gender roles and legislation (parental leave, etc). Language ability? I think, somebody should do a study showing that the more time female caretakers spend with the child, the bigger the gender gap. Sounds like a challenge.

I wouldn't assume is was deliberate. He's probably just incompetent and was showing off. Now he tries to give the blame to somebody else: wikileaks, Assange. Just guessing: after the relationship between the guardian and Assange got bad (after they published critical stories about the rape charges), he doesn't have to work so hard to convince people around him.

I just RTFA. It says the money is to
repay the city for its efforts in trying to regain control over the FiberWAN network and later test it for vulnerabilities. City officials had been worried that Childs, who helped set up the network but clashed with his supervisors, might try to sabotage it.
Mind, he already spent 2 years in custody and was convicted to 4 years of jail.

Many politicians and media personalities have been arguing similarly..

I agree that C should not be the way to go for application programming. Developers should value their own time more than they value the computer's time, even more so that computers get so fast and interpreter implementations so good that the difference is hardly noticeable. When I am looking for applications to use and have the choice of one programmed in C/C++/C#/Java and one programmed in python, I'll choose python, because I assume that the code quality is better.

I could be wrong, but shouldn't novely be a criterion for submission? ACO has been used since the early 1990s.

So he uses cell cultures as controllers for robots. I don't have access to his article now to see what he did exactly, but I doubt he can make this work efficiently.

I remember a talk about some DARPA projects after 9/11 for chemical sensing that used also alive cell cultures. Advanced chemical sensing could serve to detect explosives and chemical weapons and therefore shield again terrorist attacks. They would take a cell culture from a rat brain put it onto a dish and then characterize the responses to different kinds of currents (output from chemical sensors), so they could implement a computational model that separated these responses and made sense of them. The problem they had was that the cultures are difficult to maintain in the same state. For chemical sensing they had to be transported which was problematic, because even slight jerks would change the culture. They are very sensitive to temperature and then of course they change over time (as the introduction states). So, the would have to be adjusted again, which is time consuming and expensive. Until he finds a way to maintain the state of the network and control the intrinsic changes of the network (culture) he will have problems with stability and it will not be very useful.

Most Swiss banks won't take Americans as clients, because they don't want to get into problems with American authorities. (I learned this from "Emergency - this book will save your life.")
