The Sunday Times reports that our authoritarian Home Secretary's plans to prevent leaks from the companies working on implemented the expensive and unnecessary ID card scheme has itself been leaked.
What's particularly draconian is that it seems the desire is to implement a system whereby workers at these companies may have their homes searched without needing a search warrant.
The Y chromosome in Drosophila is a strange thing, and it has several unique features. While, just as in humans, male flies are XY and females XX, flies differ in the the Y chomosome doesn't determine "maleness". Rather the sex of the fly is determined by the ratio of X chromosomes to the number of sets of autosomes (the X:A ratio). If the X:A ratio is 1, then the fly is female, if it is 0.5, the fly is male. So an X0 fly (i.e. one with a single X chromosome with no Y chromosome) develops as a male. [This can be quite useful in the laboratory] What then is the Y chromosome for? It is required for male fertility but not viability. This means that XY flies are fertile males, XX fies are fertile females, XXY flies are fertile females and X0 flies are sterile males.
One might expect then that whatever genes are located on the Y chromosome are related mainly to fertility, or are genetically redundant. In fact there are very few known genes on the Drosophila melanogaster Y chromosome - 12, in fact, and many if not all are related to fertility in males. 12 genes is really not many for a chromosome, and it turns out that the Y chromosome is pretty much composed of genetically inert heterochromatin and largely comprises simple sequence repetitive DNA.
The nannys at the Internet Watch Foundation, the people who generate lists of websites it doesn't think we should see, have decided that customers of Virgin Media, Be/O2/Telefonica, EasyNet/UK Online, PlusNet, Demon and Opal should be unable to view the Wikipedia page about the 1976 album Virgin Killer by German metal band The Scorpions (if you've been blocked, you won't be able to see that link). OK, it's tasteless (and I never particularly cared for the Scorpions' music), but should it have been blocked?
The blacklisting of this Wikipedia page has had consequences on the ability of those UK webusers to edit Wikipedia articles.
Hot on the heels of the good news that the European Court of Human Rights has ruled that DNA fingerprint records of individuals that were not convicted may not be retained in police (or other) databases, comes less welcome news of the developing Surveillance State.
The Independent reports that the Government is to push through legislation to permit a variety of public bodies to share and exchange sensitive data they hold on us.
I got another email from the moderators over at the BT beta broadband forums. This was in response to a post I made in which I referred to another posting which mentioned BT-Webwise- here is my posting (I removed a name, indicated by ***, and I think the post is obviously a little tongue-in-cheek):
Whoops, now you've done it, ****, you've mentioned it in your sig. Well, your post has lasted 15 minutes so far!

Once again, I find myself interested in a paper about the analysis of a fossil! This time the point of interest is origin of the tetrapod limb digits. The origins of the proximal elements of the tetrapod limb are well understood, and can be seen as homologues of elements of the fins of sarcopterygian (lobe-finned fish). The origins of the digits may have been fin rays, or possibly evolutionary novelties. The latter explanation was supported by developmental genetic studies and analysis of fossils (including the subject of this paper, the transitional fish/tetrapod Panderichthys). In this paper, CT scanning was used to generate 3D images of Panderichthys limbs, demonstrating the presence of distal radials, and correcting a mistaken reconstruction.
The figure below shows the skeletal structure of the limb, coloured to show homologies to the elements of the tetrapod limb.
I've been re-reading this book, which I bought and first read when it was published 21 years ago. It is rather unfortunately out of print now, but is available online. L. Ron Hubbard was a pulp fiction writer who, after a less than distinguished wartime career in the US Navy, reinvented himself though Dianetics, later used as the basis for the pretty bizarre Scientology cult. [Note: Scientologists react to criticism fairly aggressively. Critical websites may be attacked by litigation or other means. For example, note the warnings at the Wikipedia page, and this article at The Register and entries about Scientology at Wikileaks]
New Humanist magazine (they of the humanist trading card fame) - have an advent calendar in which every day in the run up to the annual midwinter festival of conspicuous consumption one of:
a stellar selection of comedians and scientists speaks about explains which scientist or philosopher they would like to celebrate each year as a rational substitute for Jesus, as well as what scientific Winterval gift they'd most like to receive.
Today I received this email from a moderator on the BT Broadband forums:
Your recent posts titled: "Re: Internet Radio Bandwidth usage?" and "Re: How do I delete my account?" have been removed as they contravene with the Forum Guidelines.
I have installed the AntiPhorm plugin. This conducts two checks - firstly to identify if you are using BT-Webwise (by checking cookies), and secondly to check if you are using BT or one of the other ISPs who have publicly stated they are planning to implement the Phorm system. If either of these two conditions are met, you will see a warning banner beneath the web page header. You can carry on browsing the site.
If you see the warning banner, please take the time to visit the link for more information about Phorm, and its intrusive (and probably illegal) deep packet inspection by which your internet habits will be monitored in order to sendyou targeted advertising. The Phorm system is branded BT-Webwise when implemented via British Telecom. Some points:
