Has anyone here done it? I'd love to study biology at any university but won't be able to in my country (Congo). I can't afford to sit the sat exams for American universities where financial aid is far more available but have A*A*A*A* in biology, maths, further maths, physics British a levels from sitting then with a charity which went bust. I have crappy internet on an old ipad, could probably get access to a computer for Skype.

How would I go about getting a scholarship for the UK with my family (dad, 3 bros, sister)? I cannot leave them as no law and I'm only person still able to use a gun well. Sure it's pointless but worth asking anyway.

>well the lung cancer thing is more subtle but for sure tobacco smoking causes heart issues
This is derived from non-randomized epidemiological studies with ambiguities in their methodology, which captures people who already are at a higher risk for hypertension. The smoker's paradox of Japan, i.e the Japanese studies of 90s and 00s, which isolated for lifestyle and dietary factors, failed to show any increase in heart disease or even adverse cardiovascular events relative to the general population. It's a well known phenomenon that many smokers exhibit hypotension.
Tobacco smoke has pharmacological properties about it that would explain why both why such a paradoxical hypotension may be induced and the why the expected oxidative stress of the tobacco smoke on the the quick introduction to circulatory would be ameliorated:
1. Tobacco Smoke increases nitric oxide levels independent of nicotine, which exerts a vasodilatory effect.
2. Tobacco Smoke contains significant quantities of coenzyme Q10, which is very cardioprotective.
3. Tobacco Smoke contains MAO inhibitors, which, explain the paradoxical lower blood pressure in very heavy smokers; whereby norepinephrine is now partly displaced by octopamine, precipitating hypotension. Lastly, such studies as you mention consider any recent tobacco use within a given time-frame (generally a year) as a smoker; which, ignores the sudden compensatory consequences that quitting may inflict. Tangentially, terminating an MAOI therapy in most patients usually results in a transient increase in BP for a number of weeks to months (arising due to higher production of MAO enzymes in response to months or years of being inhibited). Any learned psychiatrist here who has used such pharmacotherapy can attest to this third phenomenon.

Is it worth studying Molecular Biology? I'm a first year uni student, just wanna know if this field has any potential. What do you think /sci/?

Is having 6 periods of 90 minutes of sleep the same as having 9 hours of sleep in a row?
I want to multipy my chances of having a lucid dream by six every night.
I just black out for 9 straight hours and that really rustles my jimmies.

I have depression caused by chronic loneliness and pretty deeply rooted fear of intimacy. Every time someone touches me a lot or hugs me I kind of freeze up a little bit and don't really feel like I'm really there. It is as if there is a defense mechanism/layer between me and the person.

In what area does this fall in the "science" of psychology so that I can study it more? What are some things I can do to break down this layer and lessen my fear of intimacy?
