http://www.sciencedirect.com/science/article/pii/S1359644612003674 I couldn't agree more with that article. The FDA doesn't actually require a mechanism to be explained for a therapy, as long as you say what X does and it does what you say, then you can gain approval for use. Whatever...

Right now, I'm in grade 12 and already have my courses chosen, but I chose to take a data management math course instead of biology. I don't doubt I'll enjoy the math class, as I'm interested in stats, but will not having biology close doors for me? I still haven't decided on what branch of...

Homework Statement The Xolo is the national dog of Mexico. The striking characteristic of this dog is that it has no hair. Xolos carry a mutation in Chromosome 17 that, when homozygous, is lethal. If two hairless Xolos were mated, what fraction of their surviving offspring would be...

Hey guys, (this is not homework). I am working on a "out of class" project right now, and I want to get some ideas on ways you can run an experiment in which you can apply quantum theory to biology? Thanks :)

I just graduated from high school and I want to continue my formal education by studying for a bachelor's degree in science. Biology is the science I am most keenly interested in, but here's where my dilemma kicks in: should I study Biology or Medicine? (I assume you're from the U.S., so let me...

So, I really like my biology classes. It's cool to learn things about biological systems that I can apply towards ideas of medicine. Biology encapsulates so many finds. I really like the courses but I also want a secure income down the road that will lead to an interesting career(Why I passed...

Why did you choose biology? Why not chemistry or physics? Is there something about the utter complexities of life that draw you to this discipline?

I'm thinking about majoring in bio at college next year; however, I was curious about what kind of sub specialties exist out there, beyond undergrad education. I see on the forum all the time, people talking about going into high energy physics, or condensed matter physics, or field optics, or...

I'm just sort of finalising what subjects I want to do next year before I get my results and have an enevitable 24 hr panic until I sign up for sixth forum the next day. I'm definitely going to be doing: Math w/ Further Maths (hopefully) Physics Chemistry As those are probably the...

I recently started studying biology because suddenly I started getting curious about this subject. I read about the cell theory which states that all living things have cells. Is this necessary - that all living things have cells? Can't they have some different structure? Also these type of...

Is there any textbook or any book (introductory, mostly) out there that combines the teaching of physics, biology, and chemistry phenomenon while appropriately teaching the details for each of the fields as it goes on. Or anything similar?

Hi all I'm a physics undergrad (rising year) and trying to find some kind of creative outlet for my studies in physics. I'm sort of fed up with the research academic world (at least in SS physics (solar cells) where I am now), I'm not sure if I'd want to go into other standard physics...

Hello, this is my first time to post to ask for some advice. I will try to describe as neat as possible, so that I can some good info or advice. I graduated 2 years ago with bachelor of science in biology as major and applied physics as minor. Now I'm hoping to get into graduate school in...

So my main area of research is molecular biology and biochemistry, but nuclear and particle physics frequently manages to find its way in it and it's always baffling to me. I've been participating in research on bacterial Cytochrome P450 enzymes; they catalyze the oxidation of organic...

So I'm about to graduate with a degree in molecular biology and biochemistry. I don't want to do grad school right away; I want to try to get some private sector experience first. I'm open studying pharmacology, toxicology and such, but I'm really more interested in industrial and...

Hey everyone, I'm currently a freshman in high school and I'm taking Biology. I was wondering if taking the AP Biology next year would be a good idea. This would be on top of my two other science classes; Pre-AP Chem and Pre-AP Physics. My current Biology classes is very easy. This is...

Should I take grade 12 biology?? Should I take grade 12 biology? I'm in grade 11 and I want to go into either physics or engineering but everyone tells me I should take as many sciences and maths as I can. If I go into engineering it probably won't be anything that has to do with living...

I've recently read an interesting article on the NY Times about an MIT competition on synthetic biology. A determined team about from a community college managed to get there. Good read. But what I would like to know is where can I find more information about this? * What are some good...

I've always hated biology, do you have some tools to make me like them ? Thanks, Alexandria

That's my first year in college and I'm studying Biology. I'm pretty happy with everything (classmates, teachers) but the fact is, my favorite subjects so far have been maths and statistics (and my favorite teachers were from the math department). I study biology because, since I'm not sure in...

I'm not too sure if this is the correct subforum to post this question in. Anyways I have taken Biochemistry only. I signed up to take molecular biology and I'm wondering if that is a bad idea with no previous coursework taken in genetics (the only biology college course I have taken is...

I'm not really sure what I want to do after A level yet but I've sort of narrowed it down to Physics, EE, ChE, or Materials Sci. (OK its not that narrowed down) I've worked out that if I take: Maths Further Math Physics Chemistry That I should be covered for any of those 4 courses...

I have worked in the field of wildlife biology for years and have recently switched professions to teaching. One of my biggest concerns with the current biology curriculum is that it seems way too obsessed with it's molecular aspects. I think this over-focus can be extremely harmful to the...

http://www.technologyreview.com/blog/arxiv/27628/?p1=blogs For those who might not know of the theory the goal of quantum chaos theory is to explain all of classical physics including classical chaos as emerging from quantum systems. They've had some experimental success in the past, but this...

Hello, I am a high-school student applying to universities. I like math, and I like bio. I want a career that is the cross-section between these two subjects. I've been told about computational biology and bioinformatics. Can anyone please share any familiar experiences or any insight...

Hello there, I am new to this forum and am looking for a little advice. I have to conduct a 7-minute lesson plan in front of a high school biology class as part of a selection process for a teacher residency program. I seem to be stumped on finding an activity that will; a. be within the...

I am in my first year at the university as a Bachelor of the Arts student rather than as an engineering student. Though I may be able to switch in my second year, this isn't likely given the first-year course load in the engineering school. If I were to get the B.A., would I be able to enter a...

I am torn between which I should choose. I know this sounds stupid, but for some reason I feel like if I choose biology I will be considered ''dumber'' than the engineering counterparts and therefore be less respected because biology is easier than engineering and taking the easy way out of school.

Basically I'm looking for a general Biology book on par with Linus Pauling's General Chemistry. Perhaps a step above the likes of Raven or Campbell texts. Thanks.
