  1. k-4 crystal has 3 vertices - Nitrogen family on Mathematician Theorizes a Crystal As Beautiful As A Diamond · · Score: 1

    If one looks at the K-4 crystal picture, it is composed of objects that have 3 connections. Carbon can't be used, as it likes to form 4 bonds, and the resulting two single and one double bond would deform the symmetry. The Nitrogen family on the periodic table like to form 3 bonds with symmetry. Phosphorus is also in the same column, but it can form up to 5 bonds, and I think would be troublesome to use to form the crystal.

  2. NOT necessarily true on Google Algorithm to Search Out Hospital Superbugs · · Score: 1

    Since MRSA (Methicillin Resistant Staph Aureus) is in the general population, patients treated with the typical antibiotic coverage of Ancef (a penicillin derivative) would not effectively kill the superbug lying on the patients skin. After surgery the patient develops a MRSA infection - is it from improper technique - no.
    Yes infections can occur that way, but the 2 infections my partner had last year were probably from that mechanism. One patient was a public servant who came into contact with many people, and often had to be in a locker room type environmenmt, the other was a long term nursing home patient.
    CUrrently it is not cost efective to survey everyone to see if they have resistant bugs.

  3. Benefit of SETI on 500-fold Increase in Data Flow from SETI Telescope · · Score: 2, Insightful

    They started and demonstrated that distributed computing was a viable way to solve huge problems. SOmetimes basic research doesn't have an immediately applicable product - but sometimes the groundwork they lay provides for fruitful endeavors - e.g. Apollo program. No one thought electricity would be terribly important when it was first discovered, or the phone either. Give it a chance - maybe finding aliens might make us put aside our petty differences as countries.

  4. Arguments for and against. on Arguing For Open Electronic Health Records · · Score: 3, Informative

    Every week I have some patients who have come in from far away to see me with some X-rays, MRI, CT scans. Often they are on a CD with some strange proprietary program used to display the images. Often I cant open them up and look at them, and the person has made a several hour trip almost for nothing.
    In that way old fashioned plain images are better.
    Having open source images/records would also eliminate that problem too, as I could display the images, and not have to find/buy/ download some strange/clunky program.

    Most radiologists and newer surgeons really like electronic imaging, but it can backfire on you as well.

  5. Decline in Violence may be linked to unleaded gas on Jack Thompson Claiming Games Industry in Collusion with DoD · · Score: 2, Interesting

    Small amounts of lead can stimulate people to behave in a more violent way. The majority of the decrease occurred in the early 1990's - roughly the age when when kids who were no longer exposed to leaded gas were in their teenage years. The vast majority of violent crimes are committed by men, aged from 13 to 40. So once the unexposed kids grew up, they diluted the violence pool so to speak, and have been lowering the rate ever since.

  6. Real time answer? on Embedded Linux On a Digital Stethoscope · · Score: 1

    It would be nice to hear , and have the analysis of the arrhythmia so that you could adjust the patients medications. E.G. a patient with congestive heart failure has some symptoms (subtle), and has a slight heart sound that might not be heard with a normal 'scope. Computer analysis might hear some lung crackles - indicating excess fluid, and an increase in the patient's diuretics would help them out.

    However, a caveat, most diagnoses come from the history. Maybe 5% of the time does physical exam findings actually make a diagnosis. So when your internist or family medicine MD listens to your heart and chest, it's usually just for confirmation. They've already made the diagnosis.

  7. more space = less dense traffic = traffic on Mathematicians Solve the Mystery of Traffic Jams · · Score: 1

    If you start late to leave more room, then the person in back of you does as well , and so on and so on. This results in more people waiting to start, or waiting to go faster. More traffic continues to pile up in back of you propagating the traffic jam.

  8. Most are doing it anyway - even college level on Swedish Athletes Back GPS Implants to Combat Drug Use · · Score: 1

    Recent baseball news should help confirm that, as well as the Tour de France scandals of late. The use of steroids by some "raises the bar" and so forces others into using it so they can keep their job so to speak.
    I don't think anyone is trying to fool anyone, except maybe the athletes are trying to fool us.

  9. Another solution - Have separate pro drug olympics on Swedish Athletes Back GPS Implants to Combat Drug Use · · Score: 1

    Have another Olympic/pro sports competition where competitors are allowed to use any and every drug they want - that way we can see 3 minute miles, guys bench pressing 500 KG, 130 MPH fastballs, 80 homeruns in a season. I want to see guys on so much steroids that they are permanently sweating like Giambi, from the Yankees (did I say that?), and have weird rashes on their bodies from all the metabolites being exuded through their skin. And for the regular Olympics - any positive drug test ever, and you are permanently banned from the non-enhanced Olympics.

    Same goes for pro-sports. - Maybe have them under lock and key for a month, check body muscle levels, muscle force, and blood chemistries, and compare it to other times to see if it radically changes. There are ways to see if a person is faking if they are not fully exerting themselves. Any significant variation = permanent ban, and two years salary fine.

  10. How many versions will we see of this film? on Jackson Slated to Make Hobbit Movie, Sequel · · Score: 3, Insightful

    Gold edition, 3D, directors cut? I plan on seeing it since the LOTR was soooo dang good.
    I'm really quite interested to see how Smaug is done. The 3D done well might really up the bar for many action movies, and might set a new standard.

    However, the movie still has to be good - putting lipstick on a pig still looks awful.

  11. Referring to Stalin , Mao, Pol Pot and Hitler? on How We Might Have Scramjets Sooner than Expected · · Score: 1

    All were atheists who killed large numbers of people. Hitler started out Catholic, but changed his views in the early 1940's when he saw Christianity as a threat to Nationalism and became anti Christian, but still believed in some sort of God.
    More importantly to the deaths was not their religious views, but probably their dogmatic Marxism and communist ideals.

    Body count
        Hitler 10-12 million (6 million Jews + 5-6 million Poles, Gypsies, Russians, etc) this does not include war casulties, but concentration camp victims.
      Stalin 15-50!! million (from various farm collective starvation, pogroms, etc)
      Mao 16-60 million "Cultural Revolution" similar to Stalin- outright liquidation of millions of people + deliberate starvation for the rest.
    Pol Pot - managed to reduce Cambodia's population from 7 million to 3 million.

    Total body count range from the big 4 range from 43- 120 million people.

    This study came from urban environment data - falls in cities. Falls from those heights make little difference between grass and stone apparently. Obviously landing on a nice cushy tall bush would be better than landing on stairs.

  15. Surface tension effect is minimal - urban myth on Will The Next Generation of Spacecraft Land In the Water? · · Score: 1

    That's what only a small bug can support it's weight on waters surface tension. Water is non-compressable and dense, which is what makes hitting it hard. Actually after certain speeds the ground is safer to land on, because dirt is somewhat compressable, and thus gives more of a cushion - but this is around 100 MPH or 160 KPH.

    1960's technology is only about 10% less to LEO than the newer Ares V (130,000 lbs to LEO). At least they both have Roman numeral five in the names.

  17. My comment in SI units For Lethal Height fall on Flying Humans · · Score: 1

    The height at which 50% of the people die from a fall is about 16 meters feet( actually 4 stories ). The Lethal Dose at which 90% of people die (LD 90) is approximately 28meterst , or 7 stories. At least those numbers are what we use in medicine in an urban setting. Falls outside may be cushioned by trees/ bushes,snow, etc and may change the numbers. Obviously there exists anecdotal evidence of people falling 2 meters and dieing and people who fell 6000 meters and lived, but statistically those are the numbers collected by medical literature.

    You hit the ground at about 60 KPH from a 16 meter fall, at 28 meters - about 80 KPH. Actually speeds are a little bit smaller,since I didn't take into account the effect of wind resistance and body density, and just used the simple physica acceleration formula V^2 = U^2 + 2AS

    I'm an orthopaedic surgeon, and when fall/jump from those heights, putting them back together can be a bit "tricky", and the pieces don't always go back together well. When the suicide jumper only jumps from 13 meters and lives with horrible fractures, we sometimes joke that they didn't read the literature and plan things out correctly. Now the person is depressed AND may have bad arthritic pain from their smashed joints now, or just be plain old paralyzed.

  18. Fighter pilots more like Vulcans on How We Might Have Scramjets Sooner than Expected · · Score: 4, Interesting

    I work at a major university medical center, and we often take care of pilots (current and retired) with diseases/problems not handled by the base doctors.
    All of them are calm like a brick, not even a flinch when told they had cancer.
    "OK Doc, what do I do next?"

    One of my senior partners who was a flight surgeon told me that that's what all the fighter pilots are like - almost unemotional, even when being shot down. All that stuff on TV, with the pilots screaming "WE'VE BEEN SHOT!!!! MAYDAY MAYDAY!!!" is not at all what these guys are like.

    Yes, I guess the guy could calmly express that he wanted all the gays/commies/people who don't sweep their sidewalk killed, but I don't think that that type of thinking usually lends itself to calmly expressing those thoughts - they usually come at you like a shotgun.

    Thousands of people unfortunately had that done.

  21. That's the problem with So Cal on UPS Using Software To Eliminate Left Turns · · Score: 1

    I live in Los Angeles now, after living on the East Coast big cities (NYC, Wash DC, Balt, Philly), and I have to say that SoCal has some of the most passive drivers I've ever seen, and I think it contributes to the traffic problem. If people were a little more agressive - e.g. beep/honk/flash lights at the idiot in the fast lane driving slowly, then traffic might be a bit better. Worst rubber neckers I've encountered too.

      No one EVER jumps the lights here to make a left on the green - why because everybody is still making lefts from the previous light traffic cycle.

At least those numbers are what we use in medicine in an urban setting. Falls outside may be cushioned by trees/ bushes,snow, etc and may change the numbers. Obviously there exists anecdotal evidence of people falling 5 feet and dieing and people who fell 20,000 feet and lived, but statistically those are the numbers collected by medical literature.

    You hit the ground at about 35-36 MPH from a 48 foot fall, at 84 feet - about 50 MPH. Actually speeds are a little bit smaller,since I didn't takeinto account the effect of wind resistance and body density, and just used the simple physica acceleration formula V^2 = U^2 + 2AS
