The main BIOSCI FAQ (Frequently Asked Questions) is accessible on the World Wide Web at URL http://www.bio.net/. If you can not find an answer to your question in this or other documentation, the BIOSCI technical support staff answers e-mail queries sent to biosci-help@net.bio.net We can only answer questions about the use of the newsgroups and mailing lists. We unfortunately do not have the staff to do Internet information searches or answer scientific questions. Please post those to the appropriate BIOSCI/bionet newsgroups. Contents: -------- 0) BIOSCI NEEDS YOUR SUPPORT!! 1) Using the WWW to access the BIOSCI/bionet newsgroups. 2) What to do about "spams," i.e., junk mail, ads, etc. 3) Examples of subscribing and unsubscribing to the mailing lists. 4) The BIOSCI user address and research interest directory. 0) BIOSCI NEEDS YOUR SUPPORT!! ------------------------------ BIOSCI's government funding has been expended, and we are now operating solely from advertising revenue that we have raised from our Web site at http://www.bio.net/. We need just a few minutes of your time to help us serve you. You can do two important things which will take very little time for you individually and will immensely help us continue to help you. First, please use our WWW system at http://www.bio.net/ to access the archives. You can post or reply to messages via your Web browser as described in item #1 below. Your usage helps attract sponsors. If you contact any of our sponsors, please be sure to thank them for supporting BIOSCI. It is critical for them to get this feedback if they are to continue their sponsorship for the long term. Second, if you work for a company or organization that provides products or services of interest to the biology community, please pass this message on to your marketing or marketing communications department or other appropriate group. Please ask them to help support BIOSCI by sponsoring our Web site and explain the uses and benefits of the system to the biology community. If they are interested, they can then contact us for further information at our tech support address, biosci-help@net.bio.net. 1) Using the WWW to access the BIOSCI/bionet newsgroups. -------------------------------------------------------- As of 10 December 1995, all BIOSCI/bionet full newsgroups are accessible through the World Wide Web (WWW) at URL http://www.bio.net. One can read and reply publicly or privately to both recent postings and archived messages through one's Web browser if it is configured properly to send e-mail. Each newsgroup is equipped with its own WAIS index. The main BIOSCI home page also has access to the BIO-JOURNALS Table of Contents database WAIS index and the BIOSCI user address database described in another item further below. 2) What to do about "spams," i.e., junk mail, ads, etc. ------------------------------------------------------- BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups), mailing lists, and a hypermail archive at URL http://www.bio.net/. The same postings are distributed on all media (except for a small number of mailing-list-only groups at net.bio.net). Unfortunately it is becoming a despicable practice on the Internet (by a few people out to make a fast buck) to do automated mass postings to thousands of newsgroups and mailing lists. These attempts to grab free advertising are refered to as "spams" in the usual, somewhat boneheaded, net terminology. USENET is more susceptible to this practice, and many spams originate on the USENET groups and then are passed on to the mailing lists. However, spammers also get lists of mailing addresses and hit these too, so neither medium is immune. What should you do personally if you get junk mail? --------------------------------------------------- Just delete it and move on without reading it further. Filing a protest is becoming increasingly useless because spammers are often disguising the addresses where the messages are sent from. Unless you really understand Internet mail systems, your attempt at protest by sending replies to the message will often end up being sent to the address of an innocent person that the spammer is victimizing. What can BIOSCI/bionet do to protect its newsgroups? ---------------------------------------------------- The only solution currently available is to moderate the newsgroup. If this newsgroup is already moderated, then you are in good shape. Moderation protects the USENET distribution from about 95% of the spams that are being sent to date and protects the mailing lists completely. Moderation means, however, that someone has to take the time to review each message before it goes out. We have set up software here that simply allows the moderator to forward to an address at net.bio.net messages that (s)he wishes to have distributed. This takes no more time than that needed to read the message and pass it on, say about 1 min. per message. Most newsgroups currently have a discussion leader who is responsible for their newsgroup. The discussions leaders and their e-mail addresses are listed in the BIOSCI Information Sheet which is available on the Web at http://www.bio.net/. If a newsgroup is being hit with too many junk postings, please contact the discussion leader for that group and see if there is interest in moderating the group. Please do not assume that by simply posting a complaint to the newsgroup itself, anyone on the BIOSCI staff will act on your complaint. With close to 100 newsgroups to run, the BIOSCI staff has to rely on the discussion leaders of each newsgroup to report problems directly to us at biosci-help@net.bio.net. We will moderate any of our newsgroups if the discussion leader tells us that the readership of the group wishes to do so and if a moderator is willing to do the work. For most BIOSCI/bionet groups, this entails only a few minutes of work each day. Moderating a newsgroup will resolve probably 95% of the junk postings on the USENET distribution. Unfortunately there are easy ways for determined spammers to override the moderation mechanism on USENET, but we can protect our e-mail subscribers from unwanted postings if the newsgroup is moderated. You can also access our newsgroups over the WWW at URL http://www.bio.net. While this Web interface will not stop spammers from trying to post to the groups, this will give you yet another way, besides using USENET news, to keep the junk out of your personal mail files. For those of you with local USENET news systems, the Web interface will also give you faster access to new newsgroups and recent postings. 3) Examples of subscribing and unsubscribing to the mailing lists. ------------------------------------------------------------------ PLEASE NOTE: The BIOSCI management does NOT act on subscription/unsubscription requests that are posted improperly to the newsgroups and mailing lists. People who do this only bother everyone on the lists to no avail. Please be sure to follow the proper procedures below. Gory details are in the BIOSCI Information sheets on the Web at http://www.bio.net. Below we give an example utilizing the METHODS-AND-REAGENTS list at both of our two BIOSCI sites: Users in the Americas and Pacific Rim countries who use the BIOSCI ------------------------------------------------------------------ node at computer net.bio.net: ---------------------------- A) Determine the "listname" which is the <=8 character mail address ^^^^^^^^^^^^^ for the group. These can be found in the BIOSCI Info. Sheet. For the METHODS-AND-REAGENTS group the mailing address is methods@net.bio.net. The listname is the portion of the address to the left of the @ sign, i.e., "methods". The listname is used with the "subscribe" and "unsubscribe" commands illustrated below. B) Mail all commands in the body of a mail message addressed to biosci-server@net.bio.net. Do NOT send commands to the newsgroup posting addresses! Leave the Subject: line blank, any text on it will be ignored. C) In the body of your message put one or more of the following commands with an "end" command on the last line, e.g., subscribe methods unsubscribe methods end Do NOT put your e-mail address or other text on these lines. The server only allows you to cancel your subscription if the address on your mail header matches the address on our mailing list. Please ask for help at biosci-help@net.bio.net if your address has changed, e.g., if you know you are on the list but the server tells you that you are not a member. Users in Europe, Africa, and Central Asia who use the BIOSCI node at -------------------------------------------------------------------- computer daresbury.ac.uk (also known as dl.ac.uk): ------------------------------------------------- To subscribe and unsubscribe to/from the BIOSCI lists, you need to specify the full USENET newsgroup name with "bionet-news." prepended. The USENET newsgroup names are listed in the BIOSCI Information sheet on the Web at http://www.bio.net/. For the METHODS-AND-REAGENTS list the USENET newsgroup name is bionet.molbio.methds-reagnts, thus the appropriate commands are sub bionet-news.bionet.molbio.methds-reagnts unsub bionet-news.bionet.molbio.methds-reagnts These commands are included in a message addressed to mxt@dl.ac.uk, NOT to the newsgroup mailing addresses. As usual, include the text in the body of the message as text on the Subject: line is ignored. To unsubscribe from all the lists at the UK node, use unsub bionet-news Please note that if the address in the list is different than the one in your mail message header, you will not be able to unsubscribe by this method. If you have problems, please mail biosci@daresbury.ac.uk. 4) The BIOSCI user address and research interest directory. ----------------------------------------------------------- Please take this opportunity to add your name, address, and research interest information to the BIOSCI User Address Database if you have not already done so. You can fill out the address form directly through our Web page at URL http://www.bio.net/adrform.html. The address database is reindexed nightly for WWW access (the URL is http://www.bio.net/). If you are not directly on the Internet but can reach it by e-mail, please use our waismail server to access the user directory. waismail use is described above. You can also request a user address form by e-mail from biosci-help@net.bio.net. Please check your database entry from time-to-time to see if your address information is still up-to-date. Because of our limited personnel resources, we ask that you resubmit a *complete* form to revise your entry; we only replace complete entries and do not have resources to edit old forms. ------------------------------------------------------------------- To reply to the group as well as to the originator, make sure that the address biofilms@net.bio.net is included in the "To:" field.

METHOD TO STUDY PROTOZOANS IN MARINE AND FRESHWATER BIOFILM - CAN YOU HELP ? Can you help a group of scientists working on marine and fresh water biofouling organisms from the east coast of India by suggesting a suitable method to study protozoans. During their study, they have observed a lot of protozoans in the biofilm developed on the experimental panels grazing the unicellular algae. This causes considerable modification to the biofilm composition. They have found very little literature on protozoan grazing in biofilm and would appreciate hearing from anyone who can provide suggestions of studying protozoans.

Now don't laugh, this method worked very well for measuring bacterial colony profiles around the 0 to 200 µm range. I mentioned it to Jimmy Walker in Porton on the phone a minute ago, he thought I should put it up! You can get a profile of thicknesses by blowing a very fine powder over the surface of the film, then use the fine control of a microscope (it must have calibration scales on the fine control) and focus first on a place where there is no biofilm, record the fine control reading, then take a series of measurements over the biofilm region. This can give you a profile of depths which are really quite accurate. Do it if possible in a humid/water saturated environment so the sample does not dry out or else it shrinks. The powder we used was "Roses, roses" talcum powder by AVON. Our sample of Johnsons Baby Powder was too coarse................! Good luck. Who said old technology was dead!?

I tried posting it again more clearly but it never got through. Here it is once more hopefully third time lucky! The Biofilm Club was set up as the British Biofilm Club in 1992. Although originally established for British biofilm researchers we soon dropped the 'British' and made it open to people from all over the world. At present we have 27 overseas out of about 200 members and are actively encouraging more. We maintain a presence on the Web and you will find our home page on: http://www.cf.ac.uk//biofilm_club/index.html You will find quite a lot of useful information on the Web site but I will give a brief precis of our activities now. We maintain a database of members. Our membership fee is #15 (fifteen pounds sterling) for **2 years** and half price for bona fide students. What do you get for your money? (i) At least three newsletters per annum (ii) A free copy of the book published *before* our biennial meeting at Gregynog Hall in Wales. BBC1, 2 and 3 are published. BBC4 will be published early in September this year and available at the Gregynog meeting later in the month. The book itself retails for around #22 - 25 so that membership is pretty good value! The contents pages for each of the books published so far can be found on the Web site. (iii) A chance to attend the Gregynog meeting. Maximum numbers around 100. Our very simple rules are that being prepared to give a talk by submitting a title (so far) guarantees a place at the Gregynog meeting. In spite of this we cannot guarantee that you WILL be invited to give a talk - this depends on the committee who will select a balanced programme from all those who respond. (iv) A chance to attend half or one day workshops held three times each year. For topics and programmes see our Web site. Our next workshop is on March 17th 1999 and the topics centre on modelling. I'll send another message when this is finalised but it WILL be on the Web. Our philosophy is one of simplicity. We DO NOT provide money for any speakers. The Gregynog meeting is exceptionally good value. The total cost which is full board for two full days will be around #120 (120 pounds sterling) all in. Gregynog Hall is a historic country manor house set in about 300 hectares of beautiful grounds and will include an opportunity to take part in some Welsh folk dancing called by David Stickler! We make every effort to encourage young people. Our meetings are about 40% postgraduate/post-docs. We try match this by ensuring that a similar proportion of speakers are in this category. Talks are short in order to generate good discussion!

These meetings are a continuation of the Benelux and European meetings on Diagnostic PCR. However, the scope of the meetings has now expanded to include other amplification techniques and probe technology. The emphasis of the meetings will continue to be the practical aspects and the clinical applications. The format of the meetings will also be maintained: general, introductory lectures by internationally renowned experts in the morning and free presentations in dedicated workshops in the afternoon. Poster sessions and industrial exhibits will be an integrated part of the meeting. In conjunction with the meeting a number of business meetings of the participating societies will be organised. The sponsoring companies are expected to organise some specific training and other activities before and after the meetings. The scientific part of meetings is organised by an independent international organising committee in conjunction with the European Study Group on Molecular Diagnostics and the Society of Clinical Virology. The practical aspects of the meeting are handled by Wens Travel. All parties involved invite you to become part of a tradition. Preliminary Programme Topics: ? Molecular Diagnostics and Disease Management ? Molecular Diagnostics in Clinical Pathology ? DNA-chip technology ? The Molecular Diagnostics of Antibiotic Resistance ? Molecular Diagnostics in the Developing World ? Automation in Molecular Diagnostics ? Molecular Diagnostics and Food Safety ? Standardization and Quality Control ?

Our research group thought that density gradient centrifugation might work, but then what do we use as "standards" to be able to calculate the desity based on where the cells settle in the gradient? Also, any techniques that might not need ultracentrifugation would be preferrable. Thanks in advance for your assistance. -Mark fuller@envirogen.com ------------------------------------------------------------------- To reply to the group as well as to the originator, make sure that the address biofilms@net.bio.net is included in the "To:" field.
