    Amino acid loses a hydrogen

    Hi, I'm having a brain fart. Consider the amino acid glutamate (glutamic acid): -> When it forms an ionic bond with Na+ to make MSG, the glutamic acid loses it's hydrogen on the right side. Is it that it was "oxidized"? Or what do we call the process where it loses the hydrogen...

    The general public is scientifically illiterate!

    I read the tech blog Gizmodo. They recently posted a story about Stephen Hawking. Read through the comments: http://gizmodo.com/5628375/stephen-hawking-big-bangs-happen It is amazing how many people have no concept of science. Nobody seems to even have a concept of what a theory or law...

    Medical Have you ever been to a chiropractor?

    Sorry to bump an old thread. Thank you for saying this outright. Alternative medicine is the bane of my existence. My fiance works in a spa, and a lot of her friends are massage therapists. These people have all sorts of wacky / quackery belief systems. Massage therapists are taught all...

    Does making ice take energy?

    Hi guys, Very long time, no see! Quick question: if water is left outside and freezes, was any energy consumed in the freezing process? And if so, would this energy be stored in the ice and be released when it melts? My gut is telling me that no energy is needed to freeze water...

    Can you get sick from your own dung?

    You're right. In med school they teach us that H. pylori is essentially the cause of like 90% of GI ulcers. People used to think that it was stress, but it was demonstrated that H. pylori was the culprit. Stress can precipitate the problem though, of course. And yes, chronic inflammation...

    Can you get sick from your own dung?

    Yes, you need to be exposed to something (ie, an antigen) to be able to build an immunity (antibody) to it.

    Can you get sick from your own dung?

    Well, with bacteria, for the most part, if you just looked at them with out doing anything to them, under the microscope most of them bascailly look the same (either as spheres or rods.) Gram staining is just a technique to help classify bacteria. The http://en.wikipedia.org/wiki/Gram_stain"...

    Can you get sick from your own dung?

    Yeah, I'v'e never heard anything of bacteria being linked with cancers.. Viruses, of course. But bacteria, no. I could see bacteria contributing in terms of perhaps constant inflammation on top of another initiating event.

    Can you get sick from your own dung?

    Well, if your intestines got open, and all those nice gram negative's got out and died, and released their endotoxin (lipid A component of their LPS), you could die within 5 hours. That's a problem with people who have septicemia with gram negatives.. If you kill the bacteria, you can kill...

    ObjC: Initializing a Class Object

    So how would the code operate at runtime? If the initialize method were called again, when it gets to the line: static BOOL initialized = NO; What would happen? I guess I'm stuck in my old thought of Pascal programming, where in a procedure/function any variable you declare there is only...

    ObjC: Initializing a Class Object

    Hello everyone; I've been reading a document over on Apple's Developer website, called "The Object-C Language." I'm reading about classes, and there is a part called "Initializing a Class Object" and it gives an example of how to implement an initialize method for a class: + (void)...

    C/++/# Mac development w/ XCode and C#

    Hey guys.. I wanted to tool around in developing some very simple, basic programs for my Mac using Apple's XCode and C#. I have a little backgrouund in computer programming. I unfortunately learned via Pascal, but did pascal for at least six years and then moved on to Delphi. I even...

    Cholesterol increases membrane fluidity

    Hello there; In class we learn that "cholesterol increases membrane fluidity at low temperatures, and decreases membrane fluidity at high temperatures." I can see how it would increase fluidity at low temperatures since it attachs to the lipid tails of the membrane, which would push them...

    Dieting and metabolism

    That's cool. I'm not looking to lose weight, I'm in med school biochemistry right now, and was just trying to reason out what I'm learning. We also learned that white adipose tissue secrets a chemical called Leptin that makes you not feel hunger. I wonder why we can't synthesize that and...

    Dieting and metabolism

    Hey guys; I've always heard things similar to that instead of eating three meals a day, you should spread the same amount of food over say five meals a day. Eat smaller portions, but more often. I don't understand why (if) this works. If you keep eating small amounts all day long, you...

    Global warming true or no?

    So, it is a fact that global warming and cooling occur, but it is just debatable whether or not man contributes? What does Crichton's book say regarding the subject? I know he has references to scientific materials in it, but it is misconstrued?

    Global warming true or no?

    Hey there.. My pops read a book by Michael Crichton or someone like that that basically says global warming is not occuring. Every science magazine I read continually talks about global warming and shows how physicsists, climatologists, etc, are all working on ways to help remove CO2 from...

    A Day in the Life

    This only relates to the title.. That's one of my most favorite Beatles songs. I see the phrase used all the time "A Day in the life of xxxxx". I often wonder if they are only using the phrase cause of the Beatles. I wonder how popular the phrase was before Sgt Pepper?

    People's choice to eat meat isn't (ususally?) religious. It's just personal.

    Does anyone here eat at McDonald's

    Come on guys, you gotta be able to see through the urban myth crap. You know they don't take a worm and specifically place it in the hamburgers. That is rediciulous. lol.
