What's the possibility of giving a bacterium cancer with a virus?

Something I don't understand about Bacillus anthracis is its ability to become vegatative inside of a host system and survive. I sometimes read articles that describe it having a capsule. As I understand, capsules often prevent the microorganism from being consumed by macrophages. At other times, it seems like I am reading that spores are moving through the body and don't vegetate until they are inside an environment, such as a macrophage. link Is that realistic? For a B. anthracis spore to move around the body and then only vegetate once it's inside of a macrophage? I guess that's what research says. Is it during the spore stage that an immunological response occurs, thus triggering macrophages to consume the invader? But I believe I also read about macrophages still able to phagocytise vegetative states of B. anthracis with the capsule. Is that normal behavior of a macrophage? For what I understand, macrophages typically have trouble doing that.

Would it be possible to create a virus that targets a human cancer cell and inject its genetic code to make the cancer cell create porphyrins? Furthermore, could the code be used to manufacture porphyrins that destroy the cancer cell upon light-wave contact? I read a recent edition of Scientific American, it I had the idea that perhaps using viruses to manufacture porphyrins to destroy cancer cells would be a more controlled way to destroy cancer cells.

I haven't read articles about lithium-ion batteries in a while, but I continue to think they are biased. Sometimes things just say to me, "Manufacturers trying to manipulate people like CNET." I have read articles that state review editors were given batteries that were twice as long or just very different from what has/was regularly sold in a store. If not for CNET, then many other websites. So, I've felt for the past few years that knowledge about lithium-ion batteries for laptops has been biased. I'm wondering if anyone here has any scientific knowledge about these things, the proper way to maintain them, and research that has been conducted. I've found various articles on the web that conflict. Some say to charge the battery all the way when you're done. Other articles say to keep a batter charged at 40% to 50%. The idea of keeping a batter at half-charge sounds silly if the point of the battery is having it last its full-time charge at best. It seems like the knowledge provided by various websites tends to conflict. So, does anyone know the science behind these things and proper maintenance based on their chemical, electrical, and physical properties? Not to be elitist, but for all I see, this stuff is speculation. I don't see much information sourced anywhere in the website discussing Li-Ion battery technology.

Growing up = Computer scientist Now = Math major

I was thinking, "Must be a bot built on artificial intelligence. Decent accuracy, but only one post." Nevertheless, ask and you shall receive. You could always make glassware on your own. I did the math, looked at the needed resources... and I'd have to say the total cost is around $2000 USD. I never continued the venture of scientific glassblowing. Probably not worth the time and money. Personally, I suggest you call up shops and ask if they do scientific glassblowing. Give the locals some business. Some shops work with pure cash, so there isn't any bothersome beauracracy you have to go through.

Much better, delco. That's more of the attitude you need.

What is the current state of the SFN hazmat policy in accordance with biology and chemistry? I noticed a couple people locked some threads recently that seemed legit, but I can understand why. When's the last time everyone around here talked about the hazmat policy?

If you don't have a lot of money, you might even be able to get scholarships, benefits from the U.S. governments, and more. I've met many international students who get free rides. After a while (maybe two years) the government might cut back some of the money they give out. But even having half of the tuition paid for free is nice. Or you could bum it. I've met some people who do that. I think America is becoming a little too socialist for vagrancy, though.

Higher level chemistry classes are to help a person visualize biology on a molecular level. Keyword: Visualize. To help you imagine all those atoms that create DNA. To help you imagine that protein created. Try taking a few art classes, and that will help, too. Don't worry about chemistry books. Some are good, other suck really bad. But you need to find someone who can explain it to you. And ask that person if he/she can explain it "visually." A lot of biology can be theory, visualizing, and application. The first two are the most important. The application comes as you increase your knowledge of biology. What to do? I suggest you walk into a library and read the following books after a gen. inorganic chemistry book: 1. human biology 2. Zoology 3. Botany 4. anatomy and physiology 5. microbiology Those are some very basic undergrad level things. Try doing things in that order. I guess we got rid of the 24-hour edit rule around here. Yeah, you have talents in biology already. You understand germ theory and clean things with disinfectant. You understand that food is processed through a series of complex biological and chemical processes. Just exaggerate your common knowledge of biology and how you apply it. Biology is pretty awesome. The realms of biochemistry, bioengineering, and biophysics even more so. Stuff gets pretty cool and dangerous after a while. To answer your questions, though: 1) You don't have to know everything. But you should learn to critically analyze lectures, books, and other material in order to pass an exam. The sooner you read a course book, the better off you are. 2) Sometimes things in high school are re-learned, such as study habits. Try not to let that happen.

I'll shoot at Biology: Kreb's cycle:

And not one empathic/sympathetic statement about how you care about medicine and helping people. Gee, I don't know. You're rhetoric and ability to use psychology in social situations seems incredibly lacking to me. I always aced my psychology classes. They were wayyy too easy, which is why I bumped myself to a neuroscience major. Personally, I don't like talking about grades. I hate talking about grades. Other than that, you should get some volunteer work, such as being a firefighter. Makes yourself more appealing. Or to say the least, you need more "ethos." I mean, yeah, people can get into medical schools, but know what you want to do and WHY you want to do it. Also, don't post long crap like that. Space it out into blocks.

I assume there is an accumulation of matter from space coming toward Earth. This would allow Earth to expand. Also, the amount of failed Earth experiments creating space junk, for what I assume, has let out lesser amount of mass than what space has brought into Earth's orbit. Therefore, I'm going to assume that the Earth is indeed expanding that way but not by an amazingly large amount.

Alright, I tried install a ramdisk in Windows Vista (strangles self) ... the other day... and it didn't fly too well. I tried doing it by reading some documentation about the ramdisk.sys file created for Windows 2000 and such. Yeah, I could just download someone's program and try that, but the whole pay for it otherwise use the evaluation doesn't fly with me. Ramdisk is pretty nice. I like it. Makes me feel warm and cozy inside. Unfortunately, I can't create it manually in Vista. I could use Linux, but the alsaconf issue with hda-intels isn't flying well with me, because I like sound and techno and messing on a computer while listening to techno.... *ahem* Anyone know of a way that is totally free? Otherwise, does anyone know how exactly these people selling their programs are doing this? Do linux distros with QEMU in Windows create untouchable ramdisk? I rarely spend time in a Windows distro these days.

How about reading a book about metaphysics? Metaphysics, anyone? YES, ABOVE POSTER!! That book is exactly the first thing that crossed my mind. I have been meaning to read it. A History of Magic and Experimental Science during the First Thirteen Centuries of Our Era by Lynn Thorndike

Chemistry. There was a lack of explanation when it came to visual concepts. I suspect if someone explained it better, I would have understood it better. A lot of authors suck at writing. I don't know how they get away with it in order to teach the mass public.

I'll bite. No offense, but offense. I think you guys are lame. The worst classes for me were the ones that didn't relate the the major. Simply anything that wasn't really science, unlike chemistry, physics, biology, and math. I did enjoy philosophy classes, though. I didn't go to school take a single social science course. Nor do I ever care to think much about the social sciences. I didn't care for the humanities, arts, or being subjected to learning 4 semester of the Spanish language (which I now know very well but hate; and me thinks it an aesthetically unpleasing language unlike nihongo). Going to school to be a liberal artist was not my original intention. My intention was to be a biology major with knowledge of many science topics. I don't care about art or the humanities. I like studying the Japanese language. I like studying computer science. I like studying a variety of the topics I was forced to take before I took them. Hence, I felt like I was mentally raped and my time stolen away because of silly crap, such as psychology, US history, arts of the western world, etc... I understood them well when I came. I've aced just about every course I've taken so far that doesn't relate to my major. Hence, I already understood the material. Furtherhence, sitting in those classes for 50 minutes at a time was a serious yawn, bore, and should have been against the Geneva convention. Seriously unethical. Yeah, I'm a proponent of technical vocation. I've told my professors how I feel about America and its curriculum. I tell them I think things are archaic and just a way to get money from people. They think I'm a prick. Eh.

The bullies tend to pick on what seems like an easy target. This could be based on looks, actions, or the fact they aren't hanging out with anyone. The bullies are like evil sociopaths that find victims and torture them for fun. Their reasons for release of anger can often be unknown, and sometimes it doesn't even have an etiology: Such people are born evil. I think the majority of the factors would be that bullies have a large sense of human psychology and how to manipulate people. Either that, or they have to act like thugs and get "street cred" from their peers. It's sickening how people can support such "street cred" ideaology. I once suggested that all children be taught self defense and martial arts. I supported this philosophy before some of the school shootings in America increased. If people in schools are on equal fighting ground, though, I doubt any of them will be bullied. At least, I think there would be a dramatic decrease in school fights. And if I'm wrong, at least people will have enough fair fight to kick each other's ass and feel satisfied about how much they tried. They wouldn't grow up having a large amount of misanthropy for the world. In such a technological age, the unabomber is correct about how angry, pissed off people can grow up to use technology to destroy mankind. So, an action has to be made unless more people wish to die. There needs to be an equalizer. It's too radical, though. World governments would have serious problems with that. Law enforcement would have to start shooting people or disabling them with non-violent weapons instead of attempting to use physical contact. But it would work. That's the thing. It won't happen because the government is scared of allowing people to have the power. And the adults are scared of letting the children have the power. In reality, everyone is scared. With so much fear and ignorance, a person would be blind to not notice it's a recipe for pain to occur. But hey, if the world wishes to be ignorant, let the humans die. A lot of people can rationalize the world is better with intelligent, angry people killing the stupid, ignorant ones. In all, I would have to say bullying comes from a desire to destroy. And that destruction is to create a better world for the bully.

They would disturb the ecosystem and environment. Therefore, we should not have flying cars. End of story. There goes that idea. Now, about those cool hoverboards like in Back to the Future... I want a pink one... Agree or disagree?

1) Cell & Developmental Biology 2) Cell & Molecular Physiology 3) Molecular & Cellular Pathology Pick a card. I think 3 is up your alley. There is a possibility of you either becoming real good at your field or going off on a tangent. To stay safe, I suggest picking card number two. But yeah, seriously consider three and see if you could stay focused enough with your interests.

We need new title. I'm Linux. You must have at least obtained one more post than YT from after a one year duration of his username conception on scienceforums.net to obtain or turn on this status. Otherwise, you must have over 1000 posts in the computer board within a year. And all must be relevant to computer science, and only an administrator or moderator or Bascule can give you this title. Perhaps the one more than YT should allow you to say "I'm a Mac."

Forget that stuff. We need to have workbooks. Yes, we need workbooks with solutions. And all the problems need to relate to science!

K. I want to know https part of scienceforums.net Why can't I use a permanent certificate? I don't like the temporary one. kthxbye. #_#

Some other basics: Shell TCL/TK Use what works.

So, I don't like the way the educational system work. In other words, I'm poor. socio-economics ftw What courses at a university have you earned credit via examination? I'm talking about things, such as physics, chemistry, and biology. If you did tested out of Calc II and/or III, I'm interested. I emailed a professor at the university I want to go to, and he said I would have to be an enrolled student to test out of organic chemistry. Maybe I'll take some IUAPC exam or something at the University of Illinois Urbana-Champagne. I could do the stuff at my college. But that's a waste of time. If I go to a university, I'll need the minimum 60 credits from there for the B.S. And me taking the courses at the college instead of the university means I'll need to take something in those courses' place; and I don't want to do that. The desperate choice is to take 18-credit hours at the university, knowing all the material, and maybe getting some labwork in the side. That would save "some" money, but not a lot. I've had people tell me to take these courses at the college. Supposedly I save money and effort. Uhh, but the jobs in my town suck. And if I did take the classes at the college, I could not get a job, because with the logical setting of the class times, the most sleep I could get with a UPS-type job is 5 hours. No, I don't want to do that stuff anymore. I like my pillow. I was offered a job at the college and recommended by multiple professors. But I wouldn't get more than 20 hours at minimum wage. And to me, that's not enough money. Also, I forgot to sign up for fall admissions to the university... yep... which means if I went in the spring, I couldn't take Organic II, because Organic I apparently isn't really taught in the spring, ever. I haven't seen it. Hence, me wanting to exam out of Organic I. But I'm not enrolled, so... I couldn't take the exam to the spring, and then that would be too late. I believe I have decided to work for a year instead of taking a bunch of 200-level courses. With that said, any money I make will instant be poured into a year at a university, during which I shall become more poor. I'm not too poor, so I can't get a scholarship yet. But at the same time, I want to save money by getting credit for examination. If I work for a year, I'll most likely have the rest of time hugging academic books with my eyes. I talked to my professors, and they said they would think of more intensive materials to give me if I asked for them. I'm talking about them helping me with courses the college doesn't even offer. I've learned their fields and specialties, so I can obtain some skills from them, but not a lot. Only three professors have their doctorate's. And I think only three out of 10 there are young enough to know what the universities are like now. That's the only bright side for me maybe staying at the college. But, then again, I've got a good idea of what higher-level materials I would study and how I would go about doing them, along with making papers to argue about stuff in journals. So, I figure working for a year and studying with my spare time is the better choice. Alas, I'm not sure what to do. But I do want to speed up the process, which is why I want to have credit by examination. Any experiences with testing out of the 200-level/300-level courses? Physics?
