Date: 7 Aug 1996 16:01:44 -0700 Organization: BIOSCI International Newsgroups for Molecular Biology Lines: 72 Sender: daemon@net.bio.net Distribution: world Message-ID: NNTP-Posting-Host: net.bio.net Subject: Time: 2:57 PM OFFICE MEMO Ancient life on Mars? Date: 8/7/96 In response to a barrage of phone calls and e-mails, I am passing on what I know about the "life on Mars" excitement. In 10 days an article will be published in Science by researchers at Johnson Space Center (led by David McKay), with collaborators at McGill, Savannah River and Stanford University. These workers have been studying a meteorite, ALH84001, which was found in the Antarctic but is thought to be from Mars. The rock is thought to have crystallized 4.5 billion years ago (Ga). It contains carbonate globules that are thought to have formed 3.6 Ga. The meteorite arrived in the Antarctic about 13,000 years ago. There are several aspects of the meteorite which suggest that they contain the remains of a microscopic Martian biota. 1. It contains abundant polycyclic aromatic hydrocarbons (PAHs) that are indigenous to the meteorite. PAHs are not, of themselves, indicative of life. However, ice and other meteorites from the Antarctic show far lower levels of PAHs, and are different chemically. PAHs are abundant as fossil molecules in ancent sedimentary rocks, coal and petroleum where they are derived from organisms such as marine plankton. 2. Areas of the meteorite rich in PAHs also typically contain partially dissolved carbonate globules which are orange in visible light. Many of the globules display alternating black and white rims. The Fe-rich rims consist of an aggregate of tiny ovoids intermixed with irregularly shaped objects ranging from 20 to 100 nm. These objects include elongated structures that look like nannobacteria. (I saw SEM's of these this morning and one can easily imagine that some of the elongated structures are nannobacteria in the process of cell division.) 3. There are magnetite and iron sulfide particles in the 10 to 100 nanometer size range. Simple abiogenic explanations of their formation do not allow them to coexist with partially dissolved carbonates. However, bacteria are capable of leaving this suite of biomarkers. There are terrestrial magnetite particles known as magnetofossils which are the fossil remains of bacterial magnetosomes, and are found in a variety of sediments and soils. This infomation was presented on NASA select television this morning, and I also have the page proofs of the Science article. Bill Schopf (UCLA) was at the press conference as an outside member of the scientific community. Bill is, of course, a specialist in the oldest terrestrial fossils. He is fairly convinced that the meteorite is from Mars, but is somewhat less convinced, on the basis of the evidence thus far, that the fossils are biologic in origin. One of the issues that is troubling is that the fossils are an order of magnitude or two smaller than the earliest terrestrial fossils. However, they are not out of range of modern nannobacteria. My opinion?. I certainly hope that this is the first evidence of a Martian biota because it would be the most exciting discovery ever for evolutionary biology - that is, that there was more than one origin of life. What is inevitable about evolution vs what is contingent? As Gould points out, we are not inevitable, but on a planet with a chemistry such as ours, is life based on carbon inevitable? I often make the point that, given carbon-based life and an atmosphere rich is inorganic rather than organic carbon, eventually there would be strong selection for the evolution of autotrophy and probably light-driven carbon fixation (i.e., photosynthesis). The current models suggest early Earth and early Mars were similar physically and chemically. If life is inevitable given a certain set of physical and chemical constraints, it should have arisen on early Mars as well. If not, we are left with explaining why not. But, to sound a note of caution (and paraphrasing Carl Sagan), extraordinary science requires extraordinary proof. This will certainly be a fascinating story to follow.

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.

In amoebas and other scarcely pigmented Protozoa, there is a well known diffuse reaction to light in which the entire organism, in the absence of any apparent specialization, responds by what has been understood as a sol-gel alteration of its cytoplasm, or cytoskeletal changes. It is also well known that, outside protistologic research, the subject gave birth to non-conventional speculations, in which I am not interested. Would any of you direct me to some serious review of the biophysical and protistological lore, or commenting in the list how could such phototropic reaction is thought to be physiologically achieved?

The chapters by Bovee and Jahn (8. Locomotion and behavior) and Allen (7. Biophysical aspects of pseudopodium formation and retraction) contain the information and citations. Unfortunately, this book was published in 1973 and I am not familiar with any more recent work on the subject. However, I am totally unaware of any evidence that Entamoeba has any light responses of any kind as implied by the subject line of your message. Being an intestinal parasite I doubt it sees much light! Graham From owner-protista@net.bio.net Sun Aug 25 23:00:00 1996 Path: biosci!uwf.edu!rsnyder From: rsnyder@uwf.edu (Dr. Richard A.
