    Do you suppose a computer is fast enough to trigger a laser that is being directed by shape recognition software to pick off particular hard to isolate blood viruses? I mean you would have to redirect the blood out of the body past a high res camera/laser set up then re pipe it back in again. just wondered what the speed of a computer versus the number of viruses would be.

    I am a Clinical Nutritionist working in a Paediatric Hospital. I am in the process of devising a bi-annual nutritional assessment for my patients with Sickle Cell Disease and am looking for advice on what biochemical parameters to include. From reviewing the literature, it seems that the following vitamins, minerals and trace elements would be worth measuring: zinc, vitamin B6, folate, selenium, vitamin A, vitamin C, vitamin D. Can anybody suggest any other parameters that might be worth investigating? I also plan on recording weight and height centiles and z scores and possibly also mid-arm circumference. Are there other anthropometric indices I should consider? …

    1....the plague vacilli multiply in the xenopsylla cheops and block them and force them to regurgitate and release the bacilli while biting.this is essential for their transmission 2.rabies virus enters the nerves travels to brain and causes psychological changes which cause a dog to bite any thing it comes into contact which,which is essential for virus transmission the virus also causes hydrophobia....water forms a barrier for the transmission of the virus.(its rampant in india but not there in andamon nicobar) well would you call all that coincidence>?

    I am now taking part in a class debate on stem cell research. The current resolution is "The USF(ederal)G(ovt) should increase its funding support of stem cell research. the stem cell debate has gone on for years, but what of the recent CA decision- with the $3 billion over 10 yrs? We offer therapeutic cloning as a method of gathering cells, but what of the moral imperative? When does something become "Living", when does it begin to breathe, when does it begin to think, when can it do something on its own, when does its heart begin to beat, when can it survive in vitro, on its own?? There are plently of things we can argue, but what would work against the moral situa…

    I’m doing a research on bioremediation and some inquiries come up as I went deeper, here they are: 1.- Regarding fungi, the aminoacids that are used por protein synthesis, are they obtained from external proteins or do they synthesize themselves via translation and traduction? 2.- Is there possible to produce proteins in a industrial level from rocks (chalcopyrite). If so, what kind of metabolic pathways are there for that?

    I am in desperate need of assistance! In my Microbiology class, our lab final is to figure out an unknown. I was just told mine was wrong! I am exhausted with trying to find the answer. I have Gram postitive, motile, rods in pairs and chains. And they produced endospores. All my test have been consistant and I have no clue what it could be. My Glucose and Sucrose fermentation test were positive for acid but negative for gas. My Lactose and Mannitol fermentation were negative for gas and acid. My gel liquidfacation was a positive, starch was positive, and my FAT negative. My Indole was negative, MR was negative, VP was negative, citrate was negative, nitrate was …

    This year as a science fair project, I want to test whether or not certain substances are effective against certain bacteria strains. Is this done by growing bacteria on a petri dish and then put the substances on the dishes? Where can I obtain the materials needed (petri dishes, agar, place to put the dishes in, strep throat,e. coli, salmonella, etc.) ?

    I have a REALLY bad cold (be sure you have a good antivirus program ). I'd just like to ask: Why does all of that, well, snot come out? Where does it come from? Why can my nose be clear yet I can't breathe through it? Typically one nostril is open at a time. Then suddenly it plugs up and the other opens up great. Why? Why don't we get immune to it, or make a vaccine? Just how contagious is it? Thank you.

    1Good afternoon, Good morning and Good night This is my virgin post on SFN. I am a 30 year old Australian male. I have allowed myself to be disgnosed with Hypomania within the last 9 months here in Australia. I initially diagnosed myself as Manic when travelling and working throughout Asia in 2001/02. While having displayed, and continuing to display nearly all of the characteristics of Hypomania, I in no way feel that it is all I am, can be, nor have I ever been happy with the fact that human nature inevitably always has to console it's collective 'unknowing', with the continual driven neccessity to pidgeon-hole, categorise and classify people, obj…

    Hello everyone, Hello! I am new to this forum, and I have an immunology question. I have been looking through the scientific literature for help with little success! Here it is: Does anyone know of a research that explores the relationship between the evolution of a pathogen and the general immune status of the host? In particular, I am interested in how the virulence of a pathogen (I am most interested in bacteria) may be changed while residing in a host that is immunocompromised. Might the pathogenicity/virulence be changed? Increased? Decreased? Any references or insight would be appreciated! Cheers, Brigid

    Hello everyone. I'm a student at the University of Louisville in the bio dept. I am concentrating my studies in subcellular biology and genetics. I was reviewing some notes about the nucleus and other organelles present in eukaryotes and started to recall symbiotic theory about some organelles were bacterial or archea ancestors that fused with the host cell. Anyway, my question is: Is the nucleus of eukaryotic organisms regared as a bacterial/archeal cell that fused with a host cell? If so, what are the probable species that would most resemble a modern nucleus?
