FAQ – New User Registration

Change applied 1st January 2009.

Owing to a number of apparently spurious user accounts, I’ve changed the way new user accounts are set up.  Before you can set up an account, you need to request a passcode from Robert (see “Email me” from the Main Menu for contact details).

Once the passcode is entered, you can set up a user account as usual.

Apologies for the extra level of security.

What are the Header images?

The header images are all related to Drosophila:

polytene chromosomes

Above: These are the giant polytene chromosomes found in a variety of tissues in Drosophila – these are from the salivary gland cells of the third instar larva.  Calvin Bridges (see picture of the fly lab below) devised maps based on the banding patterns of these chromosomes – maps still in use today.

wing blade clones

Above:   A close-up image of a small area of a Drosophila wing blade. Each cell on the wing blade bears a single hair.  This wing is from a fly that is heterozygous for a recessive mutation, multiple wing hairs (mwh), that causes each cell to bear a tuft of bristles.  You can see some of the cells show this phenotype: these have resulted from an event that has made these cells homozygous for mwh – we have used this to assess the function of a Drosophila homologue of the human locus WRN, mutation of which causes a progeroid condition. See our recent publication

fly lab

 Above: This a part of a photo showing members of the Morgan fly lab in the early 20th century. Those pictured are (from left to right) Edgar Anderson, Alexander Weinstein, S.C. Dellinger, Calvin Bridges, an "hooured guest", H. J. Muller and T. H. Morgan.  The occasion pictured is to celebrate Alfred Sturtevant‘s demobilisation in 1918 (he can be seen in the whole image).

fruit fly

 Above: The beast itself – this is a photograph of a male Drosophila melanogaster.


Above: The Drosophila eye is typical of insects: a compound eye composed of numerous facets – this is a scanning electron micrograph showing some ommatidia and bristles in the Drosophila eye.

FAQ – Tested web browsers

Since remodelling this website in August 2008, I have tested these pages in the following browsers and operating systems:

I don’t have access to a Mac, so have not so far evaluated browsers on that platform.

   Operating System
Browser      Linux         Windows         OSX     
 IE 6.0  n/a

see notes

 IE 7.0  n/a    n/t
 Firefox 3.0 tick    n/t
 Firefox 2.0    n/t  n/t
 Opera 9.5      n/t
 Konqueror 3.5.9   n/a  n/t
 Epiphany 2.22.2  n/a  n/t


Internet Explorer 6.0 does not handle the animations well – the toolbar buttons at the top don’t work, nor do the collapsing menu buttons to the right.

FAQ – About this website

This website is built using the Joomla! open source content management system (version 1.5.5 at the time of writing. I am using this website for several purposes:

  • To host my genealogy work.  Check out the introductory page – this material is password-protected, contact me for details. 
  • To host articles about my main interests – cycling, reading, music and science
  • To blog about interesting (to me) topics in science

Please feel free to register and leave comments on any of the articles.

FAQ – Navigation

Please note – these notes assume you are using the default template.

You can navigate via the separate menus on the left hand side of the screen.  Note that some menu items (for example, most of the Genealogy items) will only be visible if you are registeredand have logged in.  In addition the Logi/Register menu is only visible in the Home page.

The menu bar near the top of the pages includes a subset of menu items for quick navigation – many of these have sub-menus and sub-sub-menus,

At the top of the page is a “tag cloud” – this is a list of key words that may be used to bring up all stories with those tags.  The font size indicates the number of stories with that tag.  Just click on the word to see the relevant stories.
