As a person who gets cold sores and has also been diagnosed with MS, I
always sort of wondered if there was any sort of causative relationship
between the two, with the herpes virus somehow being a common factor.
As long as I can remember, I used to always suffer from
frequent, big, and painful cold sores. When I was 20, I started
getting MS symptoms. When I was on Avonex, I was still experiencing
bouts of optic neuritis with gradually increasing
scotoma, and I still got cold sores.
The optic neuritis and increasing scotoma stopped cold in their tracks
when I switched medications to Rebif... as did my cold sores. Of
course, it could simply be a coincidence, but I would be interested in
getting a more informed opinion on the matter (maybe even a study, but
from what I understand it is not easy to come by the cash for random
studies like this when it comes to MS). Some publications I have found
that I find interesting include:
http://www.ncbi.nlm.nih.gov/pubmed/7553233?dopt=Abstracthttp://jvi.asm.org/cgi/content/abstract/JVI.01649-07v1
Of course, I want to see something more rigorous and objective (i.e.,
not my own anecdotal confirmation bias) to justify my conjectured link
between the two. -
Re:Hypocritic Oath?
The work of Arthur Kellermann is probably the most comprehensive. Here's a few of his statistics. Scroll down and click on the tables for a quick overview.
The second statement is a common fact that is tought at the very basic level of (serious) selfe-defense.
The idea of defending yourself against a mugger is rediculous. Crime is the criminal's job. Would you expect to be able to outsmart him, even when he is prepared and has set everything to his advantage? Would you expect the mugger to have a chance if he say, turned up at you office and were to do your job?
The best strategy is de-escelation, so the last thing you want to do is start waving your gun about.
For more on this topic, I would recommend some of the articles at http://www.nononsenseselfdefense.com/robbers.htm
Unfortunately I could only find a study about carrying guns specifically for the workplace: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1449263 -
Re:AI? In video games?
I cannot find any citations for 3D modeling from 2D video, but I didn't look very hard. You're probably right, it's beyond current models.
I think you're missing what I'm trying to say here, though. A sufficiently advanced neural network may be able to play CS without the need for actual 3D processing.
I'm pretty sure that I'm right, but I really can't prove it without more time and a supercomputer to run it on. I'm currently writing proposal for a grant so I can model the selection pressures leading to the evolution of the human brain, if I get funding, it would be simple to modify my proposed algorithm to play CS. I'll get back to you in about 5 years with the results, assuming funding doesn't fall through.
Also, we are a little less that clueless on the design of a roach. Insects are simple, stupid creatures that are still around because they can survive in many environments and reproduce quickly. They are a poor model for any AI, as they don't show nearly as much Hebbian reinforcement as other, more "advanced", species. If we could create a mouse-level intelligence, OTOH, we could "easily" select it up to a strong AI given a few decades.

Re:AI? In video games?
I think you're under-optimistic regarding GAs.
They can, with training (just against themselves!) beat human opponents at simple turn based games (citation). That's the same level playing field you describe.
It's been 10 years of GA optimization and theory, and 10 years of Moore's law since then. Computers have much better reflexes than humans, and you're telling me that a GA couldn't beat a master at CS?
Tell you what: give me $50,000 in funding, six months to train the AI to general FPS rules (headshot, movement, general weapon effectiveness, etc.), and another six months for the GA to advance it for CS, and it will beat anything.
If I had to pick an approach to take right now, I'd partition up the tasks (defuse bomb/identify player/is friend or foe/aim for head/etc.) to various independent, co-evolving, ANNs. There might be a better way, but that approach seems have worked pretty well for these guys (albeit that's not real time).
The point is, games have rules. Once you've learned the rules, you're unstoppable.

Re:As Drug War Esculates So Does Copper Theft
On the other hand, there is a certain demographic that comes to mind that stereotypically has the construction experience and the work ethic to form a much better cognitive fit. For me, at least.
You mean mexicans? I suppose that would be reasonably easy to verify with arrest records, I'd be surprised if some criminologist hasn't checked the demographics on that. But I'm not sure how to look that up, is there an equivalent to pubmed for criminology?

Re:Near death != death
That is actually not true. What is death? When your heart stops? Are you dead when you stop breathing? Rigor Mortis? Properly diagnosed brain death seems like the only way so far, but the laws are far behind the science on that one.

Oh, yeah, on topic: I recommend using Pubmed, Google Scholar and Wikipedia to learn about this stuff, but taking a class in neurobiology is also extremely helpful. (I will definitely be checking out a couple of the books recommended here too, though).

Re:65 Celcius melting point of skin?
they had to determine the optimal temperature at which flesh melts but can still heal (about 65 degrees Celsius)
Firstly, 65C, isn't that the just above the heat of a warm bath, and doesn't a sauna reach up to 110C ? Second, since when does a skin melt?
Who can give some more indepth information about this?
PubMed: http://www.ncbi.nlm.nih.gov/sites/entrez
Nothing I can find that answers directly to the details in TFA, it is after all original research, but I find a few that are probably among the present research's predecessors, which relate the fact that various collogens are unstable and unfold or 'melt' at temperatures less than 65C, including human lung tissue that's unstable at body temperature. I used "skin melting temperature" -- other search terms may prove more fruitful.

Re:Memory RNAWell, I've not learned about RNA holding memory in any of my classes, and even Wikipedia has little to say on the subject.
I'd venture a guess that it's not correct (simply not enough evidence supporting it, but that has not yet been ruled out either.
The bottom line is that we do not yet fully understand memory, in much the same way that we do not fully understand synapse formation in the brain. We should just wait and see before jumping to any conclusions (and maybe write a grant proposal or two along the way).

True for HIV, True for HPV.
True for whatever.When you've finsihsed the HIV evidence, feel free to look up the 15,000 HPV articles (or just 12,600 if you restrict your seach to "HPV AND cancer"). The HPV thing is actually very easy: most viruses carry genes evolved to push cells into their growth phase, because that forces the cells to release and synthesise resources that the virus must hijack to replicate. HPV-associated cancer happens when the viral gene gets incorporated into the cell's DNA (rare, but through well-established mechanisms) and get permanently switched on, making the cell grow and divide constantly. Any biology undergrad could tell you that if you asked. It's more common in the cervix simply because it's out of sight, and doesn't get noticed until it's really big and nasty. (Which is why all sexually actve women should be screened: catch it within the first 5 years and the cure rate is better than 98%. It's an easy cure if you *find* it)

RISKS: Hardware-borne Trojan Horse programs

Hardware-borne Trojan Horse programs
Chris Tate <FIXER@FAXCSL.DCRT.NIH.GOV>
Tue, 8 Nov 1994 12:34:36 -0500 (EST)I had an unpleasant experience this past weekend, and I imagine some other readers of RISKS will find it interesting.
I recently purchased an Apple Macintosh computer at a "computer superstore," as separate components - the Apple CPU, and Apple monitor, and a third-party keyboard billed as coming from a company called Sicon.
This past weekend, while trying to get some text-editing work done, I had to leave the computer alone for a while. Upon returning, I found to my horror that the text "welcome datacomp" had been inserted into the text I was editing. I was certain that I hadn't typed it, and my wife verified that she hadn't, either. A quick survey showed that the "clipboard" (the repository for information being manipulated via cut/paste operations) wasn't the source of the offending text.
As usual, the initial reaction was to suspect a virus. Disinfectant, a leading anti-viral application for Macintoshes, gave the system a clean bill of health; furthermore, its descriptions of the known viruses (as of Disinfectant version 3.5, the latest release) did not mention any symptoms similar to my experiences.
I restarted the system in a fully minimal configuration, launched an editor, and waited. Sure enough, after a (rather long) wait, the text "welcome datacomp" once again appeared, all at once, on its own.
As a next step, I contacted John Norstad, the author of Disinfectant, and one of the international response team for dealing with new Macintosh virus sightings. Very promptly I received a response, which I shall quote here in its entirety (it's brief):
Yes, we have heard of this. It's a practical joke in the ROM code in some third-party keyboards. The only solution is to get your bad keyboard replaced.
I was furious. Apparently there are hardware products on the market which have embedded "Trojan Horses," programs which affect the operation of the system without the user's consent (or knowledge!).
I have returned the keyboard to the store where I purchased it, and I plan to contact Sicon about the problem. The potential for abuses in computer systems here is apparent, especially when the system involves "intelligent" peripherals - such as many popular types of disk drive, Apple Desktop Bus devices (such as the offending keyboard), and so forth.
John Norstad informs me that he has little knowledge of the extent of this particular problem, other than the fact that he has received quite a bit of mail from people who have been bitten. What is almost

Re: Is prolife was really what's about "right?"
Look up "aencephaly."
Did you mean: anencephaly
And tell me if it's fair/moral to knowingly bring this child into the world. Let me help, so you don't have to RTFA! Most of the baby's brain is missing with a gaping hole in the back of its head and it's spinal cord is mostly exposed. It will die shortly after birth, and spend its brief moment of life on meds or in agonizing pain and mother knows this for most of the pregnancy.
"A baby born with anencephaly is usually blind, deaf, unconscious, and unable to feel pain"
Source: NIH's National Institute of Neurological Disorders and StrokeThere is NO medical treatment for this, it is 100% lethal! Then she gets to watch her child die. Does this make God happy?
That's pretty far above my pay grade.
Who is this fair to, the mother, father, grandparents, or the child? Don't give me any of this it's God's plan crap. Who does it benefit to not allow this mother an elective abortion? This is only one example of many. For a human to choose death is not always wrong. Thank God for freedom of religion or freedom from it!
You are arguing for mercy killing, which most people consider to be abhorrent when applied to adults against their will. It is no better when done to children, babies, or fetuses.
Further, what you don't explain why it would be any better for the fetus to be killed in utero rather than allowing it to be born and to die a natural death -- especially considering that it cannot suffer any pain. If you intend to argue that the abortion would benefit the mother's health, then you ought to argue that point instead.
Finally, if there is one tenth of a percent chance of misdiagnosis, surely it is better to birth the baby, rather than to kill a perfectly healthy fetus in error.
As I see it, these are the basic issues, and it has nothing to do with religion, except to the extent that religion helps some people to value life. Ultimately, this sort of dispute is philosophical rather than religious, with the main question being whether life is to be valued in itself, or only in the feeling of pleasure-in-life.

Re:Er
Actually, the below is from NIMH 1 in 4 people have a diagnosable mental illness and 1 in 17 have a severe mental illness. So yes, I can honestly say more than 1 percent of the population is mentally ill.
"Mental Disorders in America
Mental disorders are common in the United States and internationally. An estimated 26.2 percent of Americans ages 18 and older â" about one in four adults â" suffer from a diagnosable mental disorder in a given year. When applied to the 2004 U.S. Census residential population estimate for ages 18 and older, this figure translates to 57.7 million people. Even though mental disorders are widespread in the population, the main burden of illness is concentrated in a much smaller proportion â" about 6 percent, or 1 in 17 â" who suffer from a serious mental illness. In addition, mental disorders are the leading cause of disability in the U.S. and Canada for ages 15-44. Many people suffer from more than one mental disorder at a given time. Nearly half (45 percent) of those with any mental disorder meet criteria for 2 or more disorders, with severity strongly related to comorbidity." http://www.nimh.nih.gov/health/publications/the-numbers-count-mental-disorders-in-america.shtml

Missing items: spam, public access, OSS, secure itIf they really want to use the Internet to move us forward:
- Make unsolicited bulk email (spam) a crime, and require that people OPT-IN to receive messages sent in bulk. The current 'opt-out' system in the U.S. is silly, and always was. Europeans have the more sensible opt-in system, so far more spam is U.S. in origin. It's not that hard to define; if more than 1000 people (say) receive it, and they didn't sign up for it (e.g., by signing up for a mailing list), it's spam. A law will not solve everything, but it would help. The current "CAN-SPAM" law is a joke - and aptly named.
- Put all federally-funded unclassified research papers on the web, with no fees or sign-ins, so that a Google search can find it. NIH is already doing this, see its public access policy: http://publicaccess.nih.gov/ Why should the public pay for research, then pay again to read it?
- By default, if the government funds unclassified software development (e.g., via research), that part should be released as open source software. Again, why should the public pay for software, then pay again to use it? Exceptions will be needed... but they should be exceptions, not the rule.
- Increase funding on efforts to protect the network and network-connected components. Some is done now, but it pales compared to the problem.

Inadvertent Hoax?
Not fraud, because they truly believed what they saw and their publications supported it. And then it went far beyond the source.
Binaural Beat, or EEG "beat frequency" brain stimulation http://en.wikipedia.org/wiki/Beat_frequency (see Binaural Beat section), as originated at The Monroe Institute http://en.wikipedia.org/wiki/Monroe_institute (TMI).
In acoustics, two beats of nearly the same frequency interfere to produce a change in summed volume of a period equal to the difference between the two frequencies. At TMI, they found that if they played sine waves into each ear of a slightly different frequency, they could detect an increase in EEG power at the beat frequency. I was so taken with an article in OMNI on TMI that I saved it for over a decade until I started studying EEG research under Karl Pribram.
Once I started studying it, a glaring error came to mind. We had to put subjects in a Gaussian cage to shield them from stray signals from the heaters and pumps for the swimming pool elsewhere in the building our lab was at. These caused induced currents in the EEG. If that was necessary, how could they justify putting electromagenticially driven headphones on top an EEG cap?
To first pull things apart, I tested a single subject -- a styrofoam head (a wig stand) with EEG cap and headphones on it. I was able to show power increases at precisely the same frequencies as the beat signal. (I'd first suggested using a bowl of Jell-O. Karl suggested not to, since he'd found increases in alpha waves in a bowl of Jell-O when shaken. No, I don't know why. Neither did Karl. We just thought it was extremely cool.)
To make it more official, I helped teach some students at University of Virginia at Wise to run EEG research. Their EEG system could produce sound remotely in a closed box and transmit it via air conduction up long plastic tubes into the ears -- no electromagnets anywhere near the head. They ran it this was as well as the traditional Monroe way (headphones on top of EEG cap). In the each of the same subjects, the traditional method produced power increases at the beat frequency. With air conduction stimuli, no changes were observed.
My two greatest joys in science are having undergrads produce results presented at international conferences, and in bursting the bubbles of old farts in the field. This particular project resulted in both. Not only did TMI present several pieces of research as valid, but many other people used the same set up and got stuff published elsewhere. Go to PubMed http://www.ncbi.nlm.nih.gov/sites/entrez and put in "binaural beat" to get the relevant results (and some not relevant, but they're easy to tell apart).
Now, you'd think that once results are presented that show it's bogus, people would quit. Not so. We did the work on 2002. Check the dates on the PubMed results. Now, that's kind of fraudulent, but more a sign that there's way too many people publishing way too many things in way too many places to be able to keep track of everything. OTOH, our work isn't in PubMed because it was a conference presentation.
What is fraudulent is the many places that produce all sorts of new agey junk based on binaural beat, claiming there's scientific evidence, but not ever quoting any, whether the original well done but slightly fatally flawed TMI work, or any subsequent. Also fairly fraudulent by TMI and all the others is claims that specific frequency differences can be used to produce specific changes such as, oh hell, here's just a sampling from TMI: http://monroeinstitute.com/store/home.php
I try to go easy on the scientific community when it comes to possible fraud claims in this area. To their credit, there used to be many more people producing work in this field, including some at U. Va. itself. In fact some from U/

Re:this pisses me off
In those experiments did the opiate blocker truly block only the opiates, or does it work on the dopamine level? A study has shown that a dopamine receptor antagonist can interfere with the function of the opiates, so unless the opiate blocker was known to only match the opiates being given, it's possible the blockage agent also blocked the dopamines generated by the placebo effect.

Which has more information:

DNA strand 2 has more information. Typing "HIV evolution" into pubmed produces 4563 papers. A little light reading to do before you get to declare that there's no evolution going on in HIV. Actually, your post is a perfect example of one of the biggest things I detest about creationism: you are personally responsible, albeit in a small and indirect manner, for the deaths of 1,000s of people by refusing to support sound science. HIV is evolving. HIV develops resistance to current treatment regimens. HIV gets even harder to treat, or cure, and people die in the process because people like you, who are willfully ignorant and proud of it put pressure on politicians to neuter science education and remove funding from studies because it doesn't fit your narrow sectarian viewpoint. Shame on you. -
Re:This is different from the OFF button how?
Dangerous implies that it is full of danger or risk, not just less safe.
I have no idea what that's even supposed to mean. Are you saying safe is a continuum, but dangerous is either yes or no? That safe and dangerous aren't different parts of one scale, like light and dark?
Requiring everyone to never use a cell phone in a car because a few make poor judgments is not fair to those that can.
And who decides who's fit to make those judgements? Most people overrate their driving ability. In fact most people overestimate their ability in general.
Is it fair to an innocent person who gets hit by another driver who thought it was OK to be using a laptop at the wheel because he's better than average, or so he thinks.
If you did that, would you stand up and take the consequences, or cry like a baby that you didn't intend to do it - as if that makes it OK and magically erases your victim's injuries? My guess is the latter.
Studies ignore the thousands or millions of people that every day use their phone in the car and do it without anyone even noticing it. Next time you are stopped at a traffic light, watch how many people are using them and doing just fine.
They also igore all the near misses, when a responsible driver manages to get out of the way of someone who's chattering away paying no attention to the road at all.
Oh, and when the cars stopped, it's pretty unlikely to hit anything.
Any other of my freedoms of choice you want to take away??

Re:I like Mono, but...

Well, here's one. Take a look at: http://wiser.nlm.nih.gov/ It uses
.Net 2.0. It was written using that because they needed something to run on Windows, Pocket PC, and provide Web Services. The apps are able to share a common middle layer and (mostly) database layer. The UI is largely shared between Windows and PPC, the web version uses a linux server that passes requests to a windows box running the web services. Works like a charm, lots of shared code, and they couldn't have done it on the PPC with Java. -
Re:i know what peer review is!!!
Here is one:
http://physicist.org/tip/INPHFA/vol-8/iss-6/p12.html
Here is another:
http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1994041
I did not mean to imply that Nature was a particular problem. Rather, I meant more along the lines of "even Nature has been a victim". Nature has in fact been in the forefront of the whole peer review discussion.
And maybe my statement was a bit strong, but I also object to another problem with peer review that often goes unacknowledged: that of rejecting research papers that contradict current popular trends. This has been an issue recently in such areas as global warming and cosmology.
So, as a "filter" (which is what it is intended to be), peer-review has more than one serious flaw; it exhibits failures at both ends. Sometimes it lets fraud through, other times it does not pass legitimate research. The former is inevitable to some degree, the latter is more a matter of closed-mindedness and I believe is more a matter of attitude problem than situational (i.e., protecting one's own professional pride, or protecting that of one's peers). As such, while both areas can stand improvement, I think the latter is the area that should be focused on as most amenable to improvement. It is also the area where peer review most impedes Science.
In any event: I agree with whoever said "peer review may have problems, but it's the best system we have." It certainly is. But that does not mean that there is not room for a lot of improvement. -

Re:Whiskey?
Whisky ages by evaporating bad alcohols while retaining tasty ones.
This statement is nonsensical. Whisky, and any other alcoholic drink for that matter, has one and only one alcohol, ethanol, C2H5OH. At least, it better, since any other form of alcohol is quite poisonous.
Most alcoholic drinks contain some methanol - and the drinks that contain more give you worse hangovers.
It is actually quite likely that methanol evaporates out of ageing significantly faster than ethanol, so he may well be right, but the main changes come from interactions with the barrel, oxidation, etc.

Re:Ultrasound
Funny you should ask that...

I have no idea as to the intensity or frequency compared between the two, and I have to point out that they blasted these mice with 30 mins of highest setting ultrasound, not realistic doses. The effects of a few misplaced neurons are also unknown, but likely not much. And, as the paper points out, no one should be using this as an excuse not to get an ultrasound for prenatal testing, the diagnostic value of it is very clear and important. But yeah, it does appear it may have an effect.

Re:"But it's just my opinion, I could be wrong"
True. But I see lots of folks at my university who are addicted to EndNote's buggy "Cite While You Write" functions that provide MS-Word integration. RefWorks has an analogous "Write while you cite" function, but still lots of people have accumulated libraries in EndNote and still have a love/hate addiction to CWYW.A lot of products provide "cite while you write"-like functionality. Zotero has CWYW-like functionality that can round-trip between MS Word and OO.o Writer. Bibus, another free/open source reference manager, also supports both word processors. Word processor support in other reference managers is detailed on Wikipedia.
Our library provides ISI Web of Science on-line....more open alternative will require freeing up all elements of the stack to include citation repositories.
Zotero plans to have a citation database that runs on a web server & plans to collaborate with the internet archive to provide storage of "open" publications (unfortunately, this excludes quite a bit of traditional content). Preprint/reprint servers, such as arXiv are a step in the right direction. Google scholar, PubMed Central, and other large repositories may help break the monopoly. If you'd like to help make your papers and citation information available to others, I encourage you to try out refbase or some other institutional repository software.
There are a wealth of APIs and standards to support this. I'm happy to say that refbase+zotero have adopted many of them. In addition to the citation style language, linked to above & which can create formatted citations form rich metadata, there is MODS XML, developed by the LoC, is a rich bibliographic format for exchange, unAPI makes it easy for websites to point to machine-readable metadata. SRW, also by the LoC, provides a uniform query language.
There are many places to follow this development, including OSS4lib, One Big Library, GCS-PCS, and many others.
