You're blowing smoke. Qualcomm wants to sell to nice, lucrative overseas markets like Japan and the EC. The government told them "don't do encryption if you ever hope to export this technology". The reason that CDMA doesn't have encryption is NOT because the G-men came a'knocking at Qualcomm's door. It's because Qualcomm doesn't think that the US market for digital cellular is big enough for them. This is just the International Traffic in Arms Regulations all over again. If you don't believe me, call Qualcomm and ASK THEM. Don't just throw out conspicracy theories. At least, don't do it on sci.crypt--there are whole other newsgroups devoted to this kind of uninformed claptrap. Hah. They're not that much more expensive. Besides, if a drug dealer can afford a Rolex and a Mercedes, he can darn well afford Cylink phones. No, Cylink sells their phones because they're willing to make different stuff for domestic use vs. export. Qualcomm isn't. So Cylink makes money--that's capitalism, comrade. "Someone" this and "someone" that. If you think it's so easy, why are you whining on the net instead of getting your butt in gear and writing it? Your name would become known and loved by dozens! But no, that would require actual EFFORT.

fc> Exactly what fraction of current research is done on the big, fc> visable light telescopes? From what I've seen, 10% or less fc> (down from amlost 100% 25 years ago.) That sounds like "dying" fc> to me... That doesn't seem like a fair comparison. Infrared astronomy didn't really get started until something like 25 yrs. ago; it didn't explode until IRAS in 1983. Gamma-ray (and I think X-ray) observations didn't really get started until the '70s. I believe the same is true of ultraviolet observations in general, and I know that extreme UV (short of 1000 Angstroms) observations, until the EUVE (launched last year) had almost no history except a few observations on Skylab in the '70s. Twenty-five years ago, the vast majority of astronomers only had access to optical or radio instruments. Now, with far more instruments available, growth in some of these new fields has resulted in optical work representing a smaller fraction of total astronomical work. fc> That would be true, if adaptive optics worked well in the visable. fc> But take a look at the papers on the subject: They refer to anything fc> up to 100 microns as "visable". I don't know about you, but most fc> people have trouble seeing beyond 7 microns or so... There are fc> reasons to think adaptive optics will not work at shorter fc> wavelengths without truely radical improvements in technology. Hmm, some of the folks in this department planning on using adaptive optics at the 5 m at Palomar for near-infrared observations (1 and 2 microns) might be surprised to hear this.

Reboost may not be a problem, if they have enough fuel. If they don't do a reboost this time, they will definitely have to do one on the next servicing mission. But try to land a shuttle with that big huge telescope in the back and you could have problems. The shuttle just isn't designed to land with that much weight in the payload. of course that is a concern too, and the loss of science during the time that it is on the ground. plus a fear that if it comes down, some big-wig might not allow it to go back up. but the main concern, I believe is the danger of the landing. Just to add another bad vibe, they also increase the risk of damaging an instrument. Finally, this is a chance for NASA astronanuts to prove they could build and service a space station. Hubble was designed for in flight servicing. bringing the telescope down, to my understanding, was considered even very recently, but all these factors contribute to the decision to do it the way it was planned in the beginning.

As I recall, it is a statistical anomaly because of the sample involved in the studies. I am certain that if it were true the Europeans would be cutting kids right & left. I think alot do it blindly because "Dad" had it done. But there are many who get bamboozled into it with the bogus cancer thing. Awhile back some quack told a friend of mine that it would help prevent AIDS. Yeah...Right! (Sarchasm) Oh YEAH ? Scene: Navy boot camp DI: "Son, you smel awful! Dont you ever clean that thing?"

... Well, lets for a hypothetical put our selves in the place of the US end of the drug rings. What do we do about the Cripple chip? First off, we would express disaproval to our congress critters, and remind them of the large sums of money our legitimate co.s provide to their campain coffers. We would also let them know via the 'other' channels that a) their income is about to take a hit, and b) their health may not be too good either. But just in case, the next obvious step to take is to BUY Mycotoxic and VLSI! Yeah, free enterprise at work. :-) Now they have the Cripple in their pockets, literaly as well as figurativly. Tough about the masses though.

In order to have formulate a rational position on what cryptography policies are acceptable, we must set forth a list of basic requirements. I would propose the following as a starting point: 1. The algorithm must be publicly known, and must have a record of surviving attempts by outside experts to find weaknesses. 2. The system implementation must make it possible to verify that the advertised algorithm is, in fact, the one that is being used. 3. The key must be quickly changeable by the user, and must be of a sufficient length and complexity to defeat any brute-force search possible now or in the reasonably near future.

I've sent Gordon R. my posts on protein, vitamin C and vitamin A prior to posting on internet as a professional courtesy. Somehow I've managed to delete my vitamin A post from my text file. Gordon R. had promised to send it back to me but he's pretty mad at me right now so I'll just retype it. Since digging through all my references is very time consuming(took me all day for that PMS post), I'm not going to cite any references(Gordon R. has them). I'm going to include some of the material from Weinsier and Morgan's new Nutrition textbook(which was not in my original material) to point out that what I'm going to say has some support in the medical community. Diet has been know to affect the immune system of man for a very, very long time. Protein has always had the biggest role in infection and I've already covered the role of protein in protecting you against infection. Now I'm going to hit what I consider to be the most important nutrient in the U.S. as far as infection is concerned(vitamin A). When vitamin A was originally discovered, it was commonly referred to as the anti-infection vitamin. Many people(Linus Pauling being one) have decided to take this title away from vitamin A and give it to vitamin C (which I've already covered). Big mistake(in my opinion). Vitamin A is also getting a reputation as an anti-cancer vitamin(with good reason). The NCI currently has numerous clinical trials in progress to see if vitamin A can not only prevent cancer but cure it as well. It's role in both cancer and infection is almost identical(but not quite). Vitamin A comes in two completely different forms(retinol and beta-carotene). Retinol is the animal form and it's toxic, beta-carotene is the plant form and it's completely nontoxic. Both retinol and beta- carotene display good absorption in the human gut if bile is present (60-80%). The liver stores all of your retinol and doles it out for other tissues to use by synthesizing retinol binding protein(RBP). A normal human adult liver should have 500,000IU to 1,000,000IU of retinol stored. We are born with 10,000IU in our liver. U.S. autopsy has shown that about 30% of Americans die with the same(or less) amount of vitamin A as they were born with. If you don't believe that nutritional reserves(like that of retinol in the liver) are important, then this low vitamin A reserve is not going to affect you. But if you believe(like I do) that the nutrient reserves are important, then there is a problem with vitamin A in the U.S. The U.S. RDA for vitamin A in an adult male is 1,000 RE or 5,000IU of vitamin A. For adult feamles its 800 RE or 4,000IU of vitamin A. Diet surveys show that most Americans are getting this amount of vitamin A (either retinol or Beta-carotene) from their diet. But the NRC(National Research Council) was going to release a new RDA table in 1985 that had the RDA for both vitamin A and vitamin C raised(C to 90mg per day and A to 7,500IU per day for adult males). That report and it's recommendations was killed. Why? Concern over the increasing supplementation was the main reason. RDAs are set to prevent clinical disease, not to keep nutrient reserves full. Many scientist in the U.S. feel that the time has come to move away from the prevention of clinical pathology concept and move towards the promotion of optimum health concept, especially since we have some very good data now that show that nutrient reserves are extremely important during periods of stress. The nutritonal concervatives won that battle and a new group of scientist were collected to come out with the 1989 RDA list which lowered the RDA for several nutrients and moved the dietary guidelines back to where they were when we first started in the 1940's(get enough to prevent clinical pathology, but not enough to fill the reserves). We know from autopsy that only about 10% of Americans have a liver with a normal vitamin A reserve(500,000IU to 1,000,000IU). I preach nutrient reserves to my students and tell them to measure them in their patients. But for vitamin A, only a liver biopsy(or autopsy data) will tell you how much somebody has stored. We can tell very easily if someone has overfilled his or her liver with vitamin A by measuring the serium retinol level(levels above 450ug/dl are highly suggestive that you have filled your liver with vitamin A and it's time to stop taking retinol). The normal range of serum retinol will be 20-100ug/dl. Hypervitaminosis A is diagnosed with a serum retinol level of 2,000ug/dl or higher(Interpretation of Diagnostic Test, Wallach, M.D., a Little Brown Series book). This level of vitamin A in blood means that medical attention is necessary due to vitamin A toxicity. Weinsier and Morgan take a much more conservative approach to vitamin A toxicity than does Wallach, as you will see later in this post. Between 450ug/dl and 2,000ug/dl you should have plenty of warning that it's time to eliminate the retinol from your diet(headache, redness of the skin, hair loss, joint pain). I tell all my students that will use vitamin A in their practice that they had better monitor the serum retinol level and stop when there are clear signs that the liver is full. You will never really know if the patient needs the vitamin A(because you can not measure the pool in liver) but you will always know when it's time to stop(just like in those vitamin A for PMS studies). Beta-carotene can be taken to fill up your liver with retinol and you will never have to worry about toxicity because the conversion of beta-carotene to retinol that occurs in both your gut and your liver will slow down(stops in the liver and slows down in the gut) when your liver is full of retinol. But taking Beta-carotene as the source of retinol takes a very long time to fill the liver up(I've seen estimates of 20-30 years) if you are in the 30% that only has as much as you were born with in your liver(10,000IU). One other problem with beta-carotene, if you have a zinc deficit, you will not convert as much beta-carotene to retinol in the gut or the liver because the enxzyme that does this conversion requires zinc. In addition, the release of retinol from the liver is a zinc dependent process so a zinc deficit will cause a vitamin A deficit even if your liver has plenty of vitamin A. Now what does vitamin A do in cancer and infection protection? The body uses vitamin A(retinol) for many different things. Vision(the first to be nailed down and where you see overt clinical pathology) uses the aldehyde (retinal) and alcohol(retinol) form of vitamin A. Reproduction uses the retinol form and some retinal. Infection and cancer protection uses retinoic acid. How do you convert retinol(which your white blood cells and the mucosal cells get from blood) to retinoic acid? You use enzymes, one of which requires vitamin C(this is why Pauling has tried to pull the title of anti-infection vitamin away from vitamin A). Vitamin C does play a role in infection(interferon production for example) but it's biggest role is the conversion of retinol to retinoic acid. If you increase your intake of vitamin C, you will increase your formation of retinoic acid. But retinoic acid can not be converted back to retinol(as retinal can) and once it's formed, it's used and then lost to the body. This is why the 1985 NRC group wanted to increase both vitamin C and vitamin A RDA's. Most people taking large amounts of vitamin C really think that they are helping themselves. If they don't have much vitamin A in their liver and they are not also increasing their intake of vitamin A, they actually do themselves more harm than good. Retinoic acid functions in white blood cells to promote antibody formation. In the mucus membrane, it is the main factor in promoting good mucus production and a good epithelial cell barrier to prevent infectious agents from entering the blood system. The mucus membrane is referred to as the "first line" defense against infection. For cancer, retinoic acid has been shown to act as a cell brake(it counteracts the effect of cell promoters which stimulate cells to divide). Cancer has two distinct steps, DNA alteration and cell promotion. For cells that normally divide all the time, promoters are not that important. But for lung and breast tissue which does not normally divide, promoters are real important in the malignant process. This is the major reason why the NCI has so many different clinical trials in progress using retinol and/or beta-carotene. Chronic infection(irritation) of the mucus membranes is a signal that vitamin A may not be adequate. I tell my students that any patient who walks into their office with a complaint of chronic infection has to be worked up for vitamin A(along with the other factors that medicine already has on it's list of causes for chronic infection). I drive this home in my course at the Osteopathic College in Tulsa, when I teach at the allopathic medical school in Tulsa(OU's branch campus) and when I give CME lectures. Dark adaptation is the best clinical test for vitamin A status since night vision is impacted when liver reverves drop to 50,000IU of retinol. The serum level of retinol can also be used, but it does not drop until liver reserves drop below 10,000 to 20,000IU. Asking a patient if they have trouble seeing at night is a good initial screen(if cataracts are ruled out). In one study done on U.S. Spanish-Americans where serum retinol levels were measured, 25% of the sample population had a serum retinol level below 20ug/dl. As more studies are done on serum retinol levels in population groups of the U.S. that have had a history of high infection rates, we will probably see a much stonger correlation between infection incidence rates and low serum retinol levels. What do Weinsier and Morgan have to say about vitamin A? Here are excerpts from their book: Vitamin A functions in vision in the forrm of retinol, it is necessay for growth and differentation of epithelial tissue, and is required for reproduction, embryonic development, and bone growth. Protein-calorie malnutrition and zinc deficiency may impair the absorption, transport, and metabolism of vitamin A. Retinaldehyde is converted to retinoic acid, which has biological activity in growth and in cell diferentiation but not in reproduction or vision. The most common procedure to evaluate vitamin A status is to measure the retinol level in plasma or serum. The normal range for vitamin A content for a child is 20 to 90ug/dl. Lower values are indicators of deficiency or depleted body stores. Serum levels greater than 100ug/dl are indicative of toxic levels of vitamin A. Dark adaptation tests and electroretinogram measurements are also useful but difficult to perform on young children. Rapidly proliferating tissues are sensitive to vitamin A deficiency and may revert to an undifferentiated state. The bronchorespiratory tract, skin, genitourinary system, gastrointestinal tract and sweat glands are adversely affected. A daily intake of more than 7.5mg(about 37,000IU) of retinol is not advised and chronic use of amounts over 20mg(100,000IU) can result in a dry and itching skin, desquamation, erythematous dermatitis, hair loss, joint pain, chapped lips, hyperostois (bony depositis), headaches, anorexia, edema and fatigue. They recommend 30mg of retinol via IM injection in children for vitamin A deficiency but do not discuss treatment for adults. Their toxic serum retinol level is very conservative. I recommend that my students try 25,000IU in adults that are having problems with chronic infection. They have to rule out a zinc deficit first by getting an RBC zinc run(or if their clinical lab can't run it, I tell them to do what Weinsier and Morgan suggest, give them the zinc along with the vitamin A. At 25,000IU per day, toxicity should not be a problem and you will not have to worry about pulling the patient into the office on a regular basis to run a serum retinol. Both Elaine and Jon found doctors who used a much higher dose of vitamin A. Recall that the PMS papers were using 100,000IU to 200,000IU of vitamin A. I don't suggest that my students use these high doses. If you wanted to fill the liver up fast(as part of a clinical trial) and were monitoring the serum retinol level, then you would be okay. But my knowledge of the vitamin A literature suggests to me that 25,000IU for patients with a demonstrated vitamin A deficit(dark adapatation test or serum retinol) will provide a good and steady improvement(as long as zinc and vitamin C status are good) without having to worry about toxicity. If they want to get more agressive, fine if they follow my advise to check the serum retinol. But vitamin A(retinol) should never be given in high dose to women who could become pregnant since vitamin A shows teratogenicity towards the human fetus. The dose needed to show this effect on the developing fetus is 18,000IU of retinol per day. Beta-carotene will never have this effect on the human fetus. Could just taking Beta-carotene instead of retinol supplements help? Yes but the effect will take a long time to develop. My advise is to use retinol to fill the liver up and then switch to beta-carotene to keep it full. Vitamin A is probably one nutrient that is better off left to prescription by doctors. But when we have the M.D.'s in this newsgroup jumping all over me and other doctors that propose the use of vitamin A supplements for treating patients with chronic sinus and GI distress, I think that the most prudent option is to keep vitamin A in the OTC market but require manufactors to provide package inserts to educate the general public about the dangers of vitamin A supplementation.

Indeed so; it's at the extreme limit of what is humanly possible. It is possible only because Mount Everest is at a fairly low latitude: there is a slight equatorial bulge in the atmosphere -- beyond what is induced by the Earth's rotation -- thanks to the overall circulation pattern of the atmosphere (air cools at poles and descends, flowing back to equator where it is warmed and rises), and this helps just enough to make Everest- without-oxygen feasible. Only just feasible, mind you: the guys who did it reported hallucinations and other indications of oxygen starvation, and probably incurred some permanent brain damage.

.. As Ben says - this re-boost idea is all news to us here. Do you know something we don't? Please supply a source - it would be nice for the schedulers of observations to know where the thing is going to be. These altitude numbers are also way off. My best source has: "Minimum ST ALTITUDE in the PMDB is: 573 Kilometers" "Maximum ST ALTITUDE in the PMDB is: 603 Kilometers" "Delta ST ALTITUDE in the PMDB is: 3 Kilometers" (PMDB is Proposal Management Data Base - used to schedule observations.) .. Could you supply some calculations? You might check some recent postings that explained that 'a small booster' as suggested does not now exist, so comparing the mass of something that doesn't exist to the mass of the OMS fuel seems impossible. The contamination threat also remains. .. Longer drag life I can understand, but could you explain the antenna pointing? Tell me about it. Although the arrays can be (and are) moved perfectly well utilizing the second electronics box. Getting them both working is much desireable so as to reclaim redundancy.

Why can't an aircraft be designed so that the pilot can always be maintained in a upright position, perpendicular to the plane of acceleration? With the visual helmets now being used that display some of the flight parameters and with a keyboard and manuvering equipment moving with the pilot, a pilot may be able to function at accelerations in excess of 12G. Is anyone currently pursuing this area or is there a reason why this is impossible at the present time?

A person I know, belonging to a research lab of a rivate company, claimed to me during a priavte conversation that, given the equipment in his lab, he could crack a Kerberos ticket in 15 minutes to an hour. He had access to rather powerful DES hardware, but not of an extraordinare kind, I believe. The attack was possible because of the amount of known plaintext in the ticket, which itself constitutes a small message. This was two years ago. DES is no longer usable for encryption of really sensitive data. For a lot of purposes, however, it is still very adequate.

"Use" may mean using PGP, or using an encrypted message. "Sell" would probably mean selling an encrypted message. It is the message created by a "patented" process incorporated in PGP, which infringes.

Hello all, There is a small problem a friend of mine is experiencing and I would appreciate any help at all with it. My friend has been diagnosed as having a severe case of depression requiring antidepressants for a cure. The main problem is the side effects of these. So far she has been prescribed Prozac, Aurorix, and tryptanol all with different but unbearable side effects. The Prozac gave very bad anxiety/jitters and insomina, it was impossible to sit still for more than a minute or so. The Aurorix whilst having a calming effect, all feelings were lost and the body co-ordination was similar to a drunken person. Her brain was clouded over. The tryptanol gave tremors in the legs and panic attacks along with unco- ordination occurred. She did not know what she was doing as her brain was "closed down". Has anyone had similar problems and/or have any suggestions as to the next step? Thankyou in advance.

There are more things in the sky than just the MBR; what I'm after is total blackbody temperature -- what a thermal radiator would see, disregarding (or shielding against) the Sun and nearby large warm objects. My dim recollection is that the net effective temperature is substantially higher than that of the MBR, once you figure in things like stars and the zodiacal light, but I'd like numbers.

They can be detached in an emergency. But expensive hardware is not thrown away casually (bearing in mind that nobody knew the design was defective). If the deployment crew had found some nasty flaw -- the lid failing to open, for example -- it would have been a bit embarrassing to have to throw the solar arrays away to get the thing back in the payload bay.

Sounds pretty familiar. I posted similar cries about last September when Caroline just entered daycare. She was two, then, and have been with continuous colds since until last March. As spring approaches, her colds slowed down. Meanwhile we grew more and more relaxed about her colds. Only once did the doctor diagnosed an ear infection and only twice she had antibiotics. (The other time was due to sinus infection, and I wished that I did not give her that awful Septra.) There are the 'net studies' -- that is, if you read this newsgroup often, there will be a round of questions like this every month. There might be formal studies like that, but bear with my not so academic experience. Okay? Gee, I bet 50/50 you'll hear cases in all these catagories. I am pretty sure, an insulated child at home sicks less. But, that child still will face the world one day. That's what I believe and comfort myself with. Caroline will get more and more colds for sure before she learned not to stick her hand in other kid's mouth nor let other kids do the same. Cold virus mutate easily. However, I hope that her immune system will be stronger to fight these diseases, so she would be less severely affected. Everytime she has a cold, we make sure she blow her nose frequently and give her Dorcol or Dimetapp at night so she can have good rest (thanks to some suggestions from the net). That's about all the care she needs from us. I try very hard to keep her off antibiotics. Twice her ped. gave me choice to decide whether she would have antibiotics. I waited just long enough (3-4 days) to see that she fought the illness off. I do understand that you don't have much choice if the child is in pain and/or high fever. If the child doesn't rely on antibiotics to fight off the sickness everytime, then the child should be stronger. I'll leave this to expert. If your child just entered daycare, I'm pretty sure the first 6 months will be the hardest. (Then, you get more used to it. Boy, do I hate to see me typing this sentence. I recall when I read something like this last September, I said to myself, 'oh, sure.' But, I do get used to it, now.) However, I do hear people say that it does get better after a year or two. I am looking forward to a healthier next winter. As it gets warmer, I hope you do get some break soon. Eat well, sleep well. Try not to use antibiotics if not absolutely necessary. Good luck. Wen-lin

Davis Nicoll sez; I'd buy that for two reasons. The tubes for TV's and radios (if you can still find them) are usually 3x or more expensive than comparable transistors. Also, ask any electric-guitar enthusiast which type of amp they prefer, and they'll tell you tube-type, since tubes have lower distortion and noise than transistors. 'Course, most of your electric guitar types just say "Tubes sound better, dude." :-) Also, transistors have the advantage in both waste-heat and energy-use, mainly because of the heaters on the cathodes of the tubes. -Tommy Mac ------------------------------------------------------------------------- Tom McWilliams 517-355-2178 wk \\ As the radius of vision increases, 18084tm@ibm.cl.msu.edu 336-9591 hm \\ the circumference of mystery grows.

The clipper chip's User key is formed by: R1 = E[D[E[N1;S1];S2];S1] R2 = E[D[E[N2;S1];S2];S1] R3 = E[D[E[N3;S1];S2];S1] Why is the triple-encrytion used? Is it just to gain an effective increase in keyspace to defeat a potential keysearch? (If so, why use 80 bit keys?) Not knowing anything about the Skipjack algorithm, it's not really possible to guess whether this makes it harder or easier to guess S1,S2. Why are N1, N2, and N3 formed as they are? It would be facinating to see the Skipjack algorithm, to look for ways of attacking it that require three ciphertext blocks formed in that odd way. Where do the 34-bit constant values that are concatenated with the serial number to form N1,N2,N3 come from? Are they changed from chip to chip, or session to session? (Even if they're published in the NY Times, if SkipJack is resistant to known-plaintext attacks, when using triple- encryption, then there's no break in security. But why allow that kind of weird format? If those three 34-bit values are truly-random bits, then maybe it's used to ensure that a known-plaintext attack on SkipJack, if it exists, can't be easily used to derive S1 and S2 for a whole production run of these chips....) Does Dorothy Denning read this group? If not, is someone on the group forwarding questions like these to her, or Martin Hellman, or anyone else who's seen more details about the chip?

I have been looking over the postings about the Clipper Chip and noticed an interesting omission from the discussion. You all mention that the algorithm is classified and have expressed concerns and ideas of how to figure out the algorithm using software. The question that I have is why cant someone take one of these chips and reverse engineer it? I mean, take the thing to a chip testing/ analysis facility, one with a decent electron microscope. Just pry off the top of the chip and start scanning it with the electron microcope and figure out the circuitry. I remembered a place that I use to work for had one of these facilities that they used to analyze chips that we accidently blew out while running tests. They could actually find the area that was fried and show us where in the circuit it was. I am sure that many companies and universities must have these facilities and that the potential is there, especially at a university where the security at such a facility is looser, for someone to take a clipper apart and analyze it? What can the government do to prevent this? Start taking away all microchip analysis facilities and electron microscopes??

My apologies if this is a re-post - I submitted it on Friday, but got a message that my post might not have gone out. Considering the confusing spitting contest over 'rights', (there are TOO inalienable rights damn it! The majority can be just as destructive of liberty as a despot), I suspect that my post did not get out of my site. (I ain't saying that dark skies are included in these rights, although we can only preserve any rights by exercising them.) Anyway, here are my thoughts on this: I'd like to add that some of the "protests" do not come from a strictly practical consideration of what pollution levels are acceptable for research activities by professional astronomers. Some of what I would complain about is rooted in aesthetics. Many readers may never have known a time where the heavens were pristine - sacred - unsullied by the actions of humans. The space between the stars as profoundly black as an abyss can be. With full horizons and a pure sky one could look out upon half of all creation at a time - none of which had any connection with the petty matters of man. Any lights were supplied solely by nature; uncorruptable by men. Whole religions were based on mortal man somehow getting up there and becoming immortal as the stars, whether by apotheosis or a belief in an afterlife. The Space Age changed all that. The effect of the first Sputniks and Echo, etc. on this view could only happen once. To see a light crossing the night sky and know it was put there by us puny people is still impressive and the sense of size one gets by assimilating the scales involved is also awesome - even if the few hundreds or thousands of miles involved is still dwarfed by the rest of the universe. But there is still a hunger for the pure beauty of a virgin sky. Yes, I know aircraft are almost always in sight. I have to live in a very populated area (6 miles from an international airport currently) where light pollution on the ground is ghastly. The impact of humans is so extreme here - virtually no place exists that has not been shaped, sculpted, modified, trashed or whipped into shape by the hands of man. In some places the only life forms larger than bacteria are humans, cockroaches, and squirrels (or rats). I visited some friends up in the Appalacian mountains one weekend, "getting away from it all" (paved roads, indoor plumbing, malls, ...) and it felt good for a while - then I quickly noticed the hollow was directly under the main flight path into Dulles - 60-80 miles to the east. (Their 'security light' didn't help matters much either.) But I've heard the artic wilderness gets lots of high air traffic. So I know the skies are rarely perfect. But there is still this desire to see a place that man hasn't fouled in some way. (I mean they've been TRYING this forever - like, concerning Tesla's idea to banish night, - wow!) I don't watch commercial television, but I can imagine just how disgusting beer, truck, or hemmorrhoid ointment advertisements would be if seen up so high. If ya' gotta make a buck on it (displaying products in heaven), at least consider the reactions from those for whom the sky is a last beautiful refuge from the baseness of modern life. To be open about this though, I have here my listing of the passage of HST in the evening sky for this weekend - tonight Friday at 8:25 p.m. EDT it will reach an altitude of 20.1 degrees on the local meridian from Baltimore vicinity. I'll be trying to see it if I can - it _is_ my mealticket after all. So I suppose I could be called an elitist for supporting this intrusion on the night sky while complaining about billboards proposed by others. Be that as it may, I think my point about a desire for beauty is valid, even if it can't ever be perfectly achieved. Regards, Wm. Hathaway Baltimore MD

There is an article in Communications Week (April 12's issue) which states definitively that not only is the justice department trying to revive the "wiretapping bill", but they are ALSO trying to find a way to force key registration. CLIPPER is an obvious thrust in exactly this direction. Dorothy Dennings is quoted in this missive. Communications Week, April 12th, page 8. Read it and get peeved folks. Then ACT NOW or lose your fundamental right to privacy. Clinton has shown us that his only interest in this has to do with abortion, and not the right of all citizens to be secure in their papers and effects.

Something similar has happened to me - ages ago when we were working on PGP we used to send short messages about development issues or simply to test new features around. Now at this time PGP (and certainly the newer version) was unknown over here. Suddenly the admin at the site I was using received a request that I stop sending encrypted email. Now there is almost no way that some automatic scanner could have found this, since they wouldn't have known about PGP - they *must* have checked for unknown data types in the message, tried to unscramble it, found they couldn't get past the PEM armour part, and then contacted the sysadmin and asked me to stop. Luckily the current email carriers are less picky about what goes over their networks :-). In case people think email scanning doesn't take place, I can assure you that it is done regularly by many sites - usually not by government agencies (or at least not that I know of), but by local administrators who, for reasons of their own, have decided to monitor all communications (I'm sure you can all think of a whole mess of reasons - stop hackers/ terrorists/child pornographers/drug dealers/evil commies/whatever). There have been several occasions when I've got people into trouble simply by including the traditional NSA bait in a message (I don't try it any more now :-). A friend of mine was once picked up for mentioning the name of the UK town of Scunthorpe (hint: look for words embedded in it). I'm sure there are many more examples of this happening (in fact if anyone has any examples I'd appreciate hearing from them - I could use them as ammunition during talks on privacy issues). Peter.

My interpretation of Denning's description is that S1 and S2 are chosen randomly by agents of the key escrow companies at the start of each 300- chip programming session. I imagine that the chips are in a carrier which will allow them all to be programmed fairly quickly - there would not be a need to transfer chips one at a time into a little PLA programmer as some people have envisioned. My guess as to why this procedure is used is that basing the keys on the S1 and S2 using a specified algorithm provides an (in-principle) checkable way to verify that no back doors exist in the choice of the random numbers used to generate the keys. Since we have to trust the escrow companies anyway, it does not weaken the system to have the keys be generated from random seeds entered by the escrow agents. And since the algorithm for key-generation is public (modulo Skipjack secrecy) then in principle an agent could challenge the procedure, ask for S1 and S2 to be exposed, and run his own independent calculation of U1 and U2 to verify that that is what is actually being put onto the floppies. And yes, there are many ways in which failures to follow this scheme could be hard to check. The laptop probably will not really be destroyed each time. Hidden cameras in the ceiling could see the S1 and S2 entered by the trusted escrow agents. Back doors in the chip could allow U to be recovered. Heck, each chip could be recorded with the same U, ignoring what was on the floppy.

Being wierd again, so be warned: Is there a plan to put a satellite around each planet in the solar system to keep watch? I help it better to ask questions before I spout an opinion. How about a mission (unmanned) to Pluto to stay in orbit and record things around and near and on Pluto.. I know it is a strange idea, but why not?? It could do some scanning of not only Pluto, but also of the solar system, objects near and aaroundpluto, as well as SETI and looking at the galaxy without having much of the solar system to worry about..

Often Shuttle lifts satellites with upper stages. Yet we still consider it payload. Ten Saturn flights over about 4 years delivered to LEO roughly the same as 50 shuttle flights over 10 years. They where pretty much the same in terms of cost/pound. A resurected Saturn would cost only $2,000 per pound (if development costs are ignored) which is five times cheaper than Shuttle. Allen

I've got a very nice collection of historical books on medical quackery, and on the topic of massage this is a recurring theme. Ordinary massage is intended to make a person feel better, especially if they have muscular or joint problems. But -- like chiropracty -- there are some practitioners who take the technique to a far extreme, invoking what seems to me to be quack science to justify their technique. In the case of massage, there is a technique called "deep abdominal massage" in which the masseur is literally attempting to massage the intestines! The notion is that undigested food adheres to the inner surface of the intestines and putrifies, releasing poisons which cause various disease syndromes. By this vigorous and painful procedure, it is alleged that these deposits can be loosened up and passed out.

Is this "White House e-mail address" really working yet? Someone posted such an address on CompuServe a few months ago, but apparently the White House wasn't really set up to recive hundreds (thousands?) of messages a day to that account and didn't want people to use it yet. So is this MCI address something the people at the White House actually read, or is it another Craig Shergold story? I don't know -- I'm just asking. Unless the people at the White House print and distribute this mail every day, you may have better luck printing out a letter (on paper, that flat white stuff all over my desk) and Snail-Mailing it to the White House.

III. ***** NEWS FROM THE WIRES ****** Sender: Jonathan Lord <jml4s@uva.pcmail.virginia.edu> Subject: RESURGENCE OF INFECTIOUS DISEASE CONCERNS CDC Date: Thursday April 15, 1993 ATLANTA (UPI) -- A resurgence of infectious diseases blamed on newly emerging viruses and bacteria pose a major challenge for the nation's health care system, federal health officials said Thursday. The Centers for Disease Control and Prevention, reporting its latest findings in an investigation of contaminated hamburger meat that sickened hundreds in 4 states and killed at least four, said it will put renewed emphasis on battling infectious diseases. Part of that emphasis includes a new series titled "Emerging Infectious Diseases" to be featured in the CDC's Morbidity & Mortality Weekly Report, which has a wide circulation in the health community. The issue also will top the agenda of a two-day meeting of scientific counselors to update the CDC's draft plan for dealing with the growing threat of infectious ailments. "This is an issue that has been coming and we do have a responsibility to deal with it," said Dr. Ruth Berkelman, deputy director of the CDC's National Center for Infectious Diseases. There were more cases of malaria in the U.S. in 1992 than in any year since the 1960s, and Latin America is experiencing a cholera epidemic, the first in this century, she said. Resistance of disease-causing agents to antibiotics is also a problem. "We are seeing much more antibiotic resistance than we have in the past" Berkleman said. She said even common ear infections frequently seen in children are becoming resistant to antibiotic treatment. "Despite predictions earlier this century that infectious diseases would soon be eliminated as a public health problem, infectious diseases remain the major cause of death worldwide and a leading cause of illness and death in the United States," the CDC said. It cited the emergence since the 1970s of a "myriad" of newly identified pathogens and syndromes, such as Escherichia coli O157:H7, a deadly bacterial infection; the hepatitis C virus; HIV, the virus that causes AIDS; Legionnaires disease; Lyme disease; and toxic shock syndrome. "The incidences of many diseases widely presumed to be under control, such as cholera, malaria and tuberculosis, have increased in many areas," the CDC said. It said efforts at control and prevention have been undermined by drug resistance. =====*===== SOURCE: WALL STREET JOURNAL REFERENCE: 04/15/93, pB1 HEADLINE: Lyme-Disease Ruling Raises Liability Issues The tick that causes Lyme disease may have found a new way to cause damage: legal liability. A federal judge's decision holding a property owner liable for not doing enough to protect workers from Lyme disease is getting as much attention as the latest medical study on the disease, a flu-like illness that can cause severe physical and mental disabilities and in rare instances death. The decision last week has put property owners on notice that they may have to do more than protect themselves from the ticks-they also may have to protect themselves from litigation if someone becomes infected while on the property. The decision by U.S. District Judge Robert J. Ward in New York came after a week-long trial in a case involving four track workers for the Long Island Railroad. Judge Ward found that the workers contracted the disease after they were bitten by ticks while on the job. He ordered the New York state-owned commuter line to pay the workers more than $560,000 to compensate for pain and suffering, in addition to medical expenses and lost wages. Summer camps, schools, companies with facilities in rural or semirural areas, and homeowners who rent to vacationers are among the groups that need to be worried about this ruling, says Stephen L. Kass, an attorney at New York law firm Berle, Kass & Case, who wrote a legal article three years ago warning property owners of the potential liability. Even a family that invites friends over for a backyard barbecue might be potentially liable. Lawsuits for insect bites, while rare, aren't unheard-of. A summer vacationer in Southampton, N.Y., last year sued the owner of the home she rented, claiming that a tick on the property gave her Rocky Mountain spotted fever. In 1988, also on Long Island, a jury ordered an outdoor restaurant to pay more than $3 million to a patron who was stung by a bee, causing an allergic reaction and permanent quadriplegia. The judge later threw out the award, citing no evidence that a beehive was near the restaurant. But lawyers say that the attention to Lyme disease throughout the country -- it's most prevalent in New England, the Middle Atlantic states, Wisconsin, Minnesota and the Northwest -- may make this particular insect bite a particularly litigious one. The illness already has proved to be a source of controversy in the courtroom over such issues as the type of medical care insurers will cover and medical malpractice claims against doctors for not diagnosing the disease. Lawyers say worker's-compensation claims related to Lyme disease have become common in some states in recent years. Payments in worker's-compensation cases, however, are limited to medical costs and lost earnings. The case before Judge Ward dealt with a potentially much more lucrative avenue for damages, because it involved the question of negligence. Unlike the worker's compensation process, the law governing injuries to rail workers allows for a finding of negligence and, as a result, for additional payments for pain and suffering. Property owners and lawyers say that negligence claims can be made in many other situations where people are exposed to the ticks that carry the disease. Ira M. Maurer, a partner at New York law firm Elkind, Flynn & Maurer, who represented the rail workers, says the decision will help to establish "the duty of all sorts of property owners to protect against Lyme disease." Lawyers caution that despite Judge Ward's decision, winning a lawsuit for damages caused by Lyme disease may prove difficult. For one thing, victims have to demonstrate that they have pinned down when and where they got the tick bite. Judge Ward found that the plaintiffs in the railroad case got Lyme disease while working on property owned by the railroad, even though none of the men remembered being bitten. The workers, who weren't outdoorsmen likely to be exposed elsewhere to the insects, said they saw ticks in the high grass that surrounded some work sites. A spokeswoman for the railroad says that there was no proof that the four men were bitten while on the job and that the railroad is considering an appeal. The railroad also disputes Judge Ward's finding that it didn't do enough to protect employees. The spokeswoman says the railroad provides track workers with insect repellent and special pants to protect against bug bites. Debate in the scientific community over Lyme disease could open up some legal defenses for property owners, such as questioning whether a victim actually has the disease rather than some other illness. Earlier this week, the Journal of the American Medical Association reported that doctors overly diagnose patients as having Lyme disease. And damages awarded to a victim also might be influenced by medical disputes over the degree of harm that Lyme disease causes. Because of health and safety concerns, some groups and companies already take special measures to protect against Lyme disease. Last year, at its headquarters in Franklin Lakes, N.J., Becton, Dickinson & Co. began using Damminix, a pesticide made by EcoHealth Inc. of Boston that is designed to kill ticks carrying the disease. The medical- supply company's headquarters include a 120-acre park, and the company was worried that employees who walk on its trails for recreation might get infected. Ruth Lister, a spokeswoman for the American Camping Association in Indianapolis, says that many youth camps accredited by her organization also have begun to check children for ticks. And Carole Katz, a member of the board of the Fire Island Pines Property Owners Association, says her group spends $30,000 each year to treat their 100-acre site off the coast of New York with the tick-killing pesticide. =====*===== TITLE: Urinary dysfunction in Lyme disease. AUTHORS: Chancellor MB; McGinnis DE; Shenot PJ; Kiilholma P; Hirsch IH, Department of Urology, Jefferson Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania. REFERENCE: J Urol 1993 Jan; 149 (1): 26-30 Lyme disease, which is caused by the spirochete Borrelia burgdorferi, is associated with a variety of neurological sequelae. We describe 7 patients with neuro-borreliosis who also had lower urinary tract dysfunction. Urodynamic evaluation revealed detrusor hyperreflexia in 5 patients and detrusor areflexia in 2. Detrusor external sphincter dyssynergia was not noted on electromyography in any patient. We observed that the urinary tract may be involved in 2 respects in the course of Lyme disease: 1) voiding dysfunction may be part of neuro-borreliosis and 2) the spirochete may directly invade the urinary tract. In 1 patient bladder infection by the Lyme spirochete was documented on biopsy. Neurological and urological symptoms in all patients were slow to resolve and convalescence was protracted. Relapses of active Lyme disease and residual neurological deficits were common. Urologists practicing in areas endemic for Lyme disease need to be aware of B. burgdorferi infection in the differential diagnosis of neurogenic bladder dysfunction. Conservative bladder management including clean intermittent catheterization guided by urodynamic evaluation is recommended.

These substances are normally not the secret, but how to get at them. The method of preperation is normally patented, which means that no-one else can make the chemical in the same way, without undergoing an agreement with American Cyanamid. (But I guess you knew what a patent is :-) ) If you know what substance is used, you'll also know its toxicity. The Luminol reaction has the disadvantage of not lasting as long as the commercial version. Remember that cyano compounds are found in nature, and not all are poisonous. Regards,

Since you asked, the above is a bit inaccurate. More accurate is that the government says its solid, other people in the field who might be able to find out haven't yet done their review of the chip design, and there's been a lot of wild speculation and guesswork from those with little information that it might be Swiss cheese.

The problem is, the people are not having the scope, or implicataions pointed out to them. Hell, most haven't even heard of Clipper, and when they do, it will be in soothing language telling everyone how nice the government is at 'letting them have' privacy. How come the media is not telling about the provisions of the Clipper decision? The provisions of the Crime Bill? The abuses of Civil Forfeiture? The government uses polls to support 75 percent of the people want gun bans, etc., yet the same pollsters have determined (according to the media) that 30 percent of the people are unaware of what the Holocaust is... The people cannot be expected to give decent decisions when they are denied the information that all these abuses and whittling away of rights are going on quietly. When they find out (when it hits them), it will be too late. One cannot expect each citizen to spend all their time probing, searching, researching, etc. For example, how big a percentage of the average population even has access to USENET? Way less than 1 percent, I bet. How many outside of Internet/USENET are even AWARE of what Big Brother is doing, or have been exposed to arguments of both sides of the issue? What the public will get is only ONE side: The Government's side. THAT is scary. < <This saddens and frightens me. < <I am a conserveative believe it or not. A law and order conserveative. <But the move to a centralized authoratarian regime really scares me, <mostly because I know you cant go far wrong underestimating the <intelligence of the American people. Tell them it's going to keep <them safe from drug dealers and terrorists, and they will let you <put cameras in their home. How can the bulk of the people be informed, when the media refuses to do it? <Even in the wake of Waco, you find those who support the increasingly <totalatarian moves. < <>Somebody once said something like: "Armed Violence is meant only to be <>used in response to an armed attack. It is not meant to be used in <>agression. This is the difference between self-defence and murder." < <To be quite honest, the way things are going, I'd call it self defense. < <>Let's try to avoid killing things, eh?

Here is a potentially dumb question: What prevents the martian landers themselves from "polluting" the martian environment with earth based critters? Is the long trip in cold radiation bathed space enough to completely sterilize the landers? I could imagine that a few teeny microbes could manage to get all the way there unharmed, and then possibly thrive given the right circumstances.

We've been progressing towards that goal for 30 years now. We precede any orbiting mission with flyby missions. Of course, it gets harder to do as we work our way farther away from Earth. We're just starting to work out to the outer planets: Galileo will orbit Jupiter, and Cassini around Saturn.

I'm a nursing student, and I would like to respond to #66966 on haldol and the elderly. Message-ID: <25APR199316225142@fsphy1.physics.fsu.edu> Organization: Florida State University - School of Higher Thought News-Software: VAX/VMS VNEWS 1.4-b1 First, I'm sorry to hear that you have had to see your grandmother go through this. I know it has to have been tough. There are many things that can cause long term confusion in elderly adults. The change in environment can cause problems. Anesthetic agents can cause confusion because the body cannot clear the medicines out of the body as easily. In addition, medications and interactions between medications can cause confusion. As far as whether or not haldol can have long lasting effects even after the drug has been discontinued, I do not know. I have not _seen_ anything to that effect. However, I also had not been looking for that information. I can see what I can find... I can tell you that haldol is an antipsychotic drug, and, according to the Nursing93 Drug handbook, it is "Especially useful for agitation associated with senile dementia" (p. 400). It also should not be discontinued abruptly. It did not say anything about long lasting effects. Because so many things can cause confusion, it is hard for me to know what else was going on at the time; if I had more history, i might be able to answer you better. If you want to send me e-mail with more information, I would be happy to try to help you piece together what might have happened.

Why not? It hasn't been released, so there's no way for you to evaluate it yet. After all, Apple could have been smart and had AOCE use an MD5 hash encrypted with RSA, just like PKCS signatures. They could even be actually PKCS compliant, for all you know; why not wait until it is released, and hard information is available, before passing judgement on it? AOCE's algorithm's aren't secret because Apple's being fascistic--AOCE itself remains secret (except for Apple demos at MacWorld :)), simply because it's not done yet. It may be flawed, and it may not. However, you can't tell which until you actually see it. I, at least, am quite impressed with what I have seen so far, and have no expectation of being disappointed.

[...] No no no no no no no. It will go like this: FEDS: We need the key to phone 334RE67D99. ESCROW: You have a warrant to tap the line phone 334RE67D99 is on? FEDS: Yes. ESCROW: Fine, here is our key. What happens is, Feds tap a line; find Clipper is being used; extract serial number; get key; decipher convo. The serial number is never registered to a specific owner, it is _sent_ as part of the conversation. If I give you my Clipper phone, you do not need to re-register it (mainly because it was never 'registered' to me in the first place). There are a lot of things that bother me about Clipper, but this is not one of them. Let's get our facts straight and not waste effort demolishing straw men. RA rogue@cs.neu.edu (Rogue Agent/SoD!)

Interstellar grains are not at all close to blackbodies. The "large" grains have sizes of order 0.1 micron and absorb visible light with fair efficiency. However, at temperatures below 100 K, 90% of the thermal emission will be beyond 22 microns, where radiating efficiency is poor. (A small antenna cannot easily radiate at long wavelengths.) Thus the grains must heat up more in order to radiate the energy they have absorbed. Moreover, the IRAS observations had a maximum wavelength of 100 microns. Grains colder than 30 K will radiate primarily at longer wavelengths, and IRAS would be relatively insensitive to them. In the extreme limit, grains as cold as 5 K will be almost undetectable by any conceivable observation. Worse still, IRAS color temperatures are heavily contaminated by a population of "small" grains. These grains have only perhaps 50 atoms, and when they are hit by a single photon they heat up to temperatures of several hundred or 1000 K. Of course they cool quickly and then stay cold for a while, but _when they are radiating_ the characteristic temperature is several hundred K. Even a small population of these grains can dramatically raise the observed "average" temperature. A model for local infrared emission consistent with COBE data has three components. These represent scattered radiation from Zodiacal dust (color temperature 5500 K), thermal emission from Zodiacal dust (Tc = 280 K), and thermal emission from Galactic dust (Tc=25 K). At the ecliptic poles, the emissivities or dilution factors are respectively 1.9E-13, 4E-8, and 2E-5. The first two are roughly doubled in the ecliptic plane. To find the thermal equilibrium temperature, we add up the dilution factor times the fourth power of temperature for all components, then take the fourth root. In the table below, starlight comes from Allen's number that stellar emission from the whole sky is equivalent to 460 zero mag stars with B-V color of 0.75. No doubt careful work could do much better. (The person who suggested starlight had a dilution factor of E-4 must have been remembering wrong. We would be cooked if that were the case. In any event, the energy density of starlight comes out about the same as that of the microwave background, and I believe that to be correct.) Dilution Temp. DT^4 Microwave background 1 2.7 53 Galactic dust 2E-5 25 8 Zodiacal dust (emission) 6E-8 280 369 Zodiacal dust (scattering) 3E-13 5500 275 Starlight 1E-13 5500 92 ----- 797 The fourth root of 797 is 5.3 K. Outside the Solar system, the result would be 3.5 K. I find these results surprising, especially the importance of Zodiacal dust, but I don't see any serious mistakes.

I don't think they can do that without changing the law. The chip itself isn't classified, and reverse engineering is allowed by law (possibly) unless prohibited by a valid contract. The algorithm may be classified, but there are many court cases ruling that information identical to classfied information, but obtained from unclassified sources, is freely publishable (with the possible exception of nuclear weapon information.)

We would like to keep it that way. Thats the point. By reacting strongly and forcefully now, we will assure that we continue to remain free. You cannot overreact to a threat like this. The worst that happens if we overreact is that we waste time and effort. The worst that happens if we underreact is tyranny. I prefer overreaction myself. Doesn't that tell you how precious and hard to maintain freedom is? Only through centuries of overreaction have we managed to maintain ourselves in this state of even moderate freedom. I suggest that overreacting now and in the future is a good thing. -- Perry Metzger pmetzger@shearson.com

[deleted] [deleted] Ok, so those scientists can get around the atmosphere with fancy computer algorythims, but have you looked ad the Hubble results, the defects of the mirror are partially correctable with software (see those jupiter pictures for results), but is the effects are completely reversable, why is there going to be a shuttle mission to fix it? The way I see it (and please, astromomers give me a swift net-kick in the butt if i'm out of the ball park), the astromers are making the best of limited possiblities, there's only one hubble, and the shuttle makes another in the near future a non-thought. Perhaps those self same billboards could have small optical receptors of a limited kind mounted on the reverse sides of the mirror's (if that is what is used) and then the whole thing becomes a giant array telescope... --

I know its semantics, but the "no-op" _doesn't_ do anything. The Command Loss Timer is simply looking for a command, any command. A "no-op" is simply a spacecraft command that drops bits into the big bit bucket in the sky. "No-op" also get used as timekeepers to provide millisecond delays between command sequences (used on the thruster preps on GRO, er, Compton) and to verify command links at the beginning of TDRS events. All in all, a rather useful command. And, an intelligent FDC test on Galileo (the Command Loss Timer).

We know that sermon. It is posted roughly every month or so by different persons, and that doesn't make it any better. How did you get the idea that skeptics are closed-minded? Why don't you consider the possibility that they came to their conclusions by the proper methods? Besides, one can come to a conclusion without closing one's mind to other possibilities. I you don't agree with a person, please ask him why he thinks like that, instead of insulting him. Perhaps he's right. Follow your own advice, be open-minded. If you don't post a bit of evidence for your claims, I'll complain that it's always those "neither a real believer, nor a disbeliever" types who narrow-mindedly judge others without knowing their motives.

I've seen children do this and wondered about something. If the mucus in one's nose collects (filters) particles going into the airway, if a child then picks and ingests this material, might it have a vaccinatory effect, since if the body ingests airborne diseases or other 'stuff' on the mucus, the body might generate antibodies for this small "invasion"? Maybe this is why some children don't get sick very often? :-) - tom

Hmm. This is certainly among the things I would refer to as quack therapy and would tend to refer to any practitioner who prescribed laetrile (whether licensed or not) as a quack. There are unethical behaviors (such as ordering unneccessary tests to increase fees) which I would not lable as quackish, but prescribing known ineffective therapies seems to me to be one of the hallmarks of a quack.

SO who certainly never reads Usenet, let alone Sci.med, said quite spontaneously " There are a lot of mushrooms and toadstools out on the lawn at the moment. Sure that's not your problem?" Well, who knows? Or maybe it's the sourdough bread I bake? After reading learned, semi-learned, possibly ignorant and downright ludicrous stuff in this thread, I am about ready to believe anything :-) If the hayfever gets any worse, maybe I will cook those toadstools...

I'd guess this was a garbled report of the NERVA effort to develop a solid-core fission rocket (the most mundane type of nuclear rocket). That was the only advanced-propulsion project that was done on a large enough scale to be likely to attract news attention. It *could* be any number of things -- the description given is awfully vague -- but I'd put a small bet on NERVA.
