Need some advice. Tossing up between continuing my bachelor of science (only completed 1 semester) or changing to a bachelor of agriculture which is aimed more at what I want to do (Agronomy) I feel as though I wouldn't get an agricultural job with a bachelor of science. And should I travel to a prestigious University to study? or study at the University in my own home town. Any advice is much appreciated as I am having a hard time with these decisions and 3 years is a big commitment and I dont want to finish one then look back wishing I chose the other one. I am Australian if that matters. Thanks

  1. Inoculate appropriate (liquid) culture medium with some non-pathogenic, non-sporulating bug.
  2. Split the broth between two sterile electrolytic cells (to rule out the influence of the electrodes or whatever).
  3. Apply suitably high voltage to one of the cell, for a suitable amount of time.
  4. Wait for the bugs to multiply, then compare optical density.
  5. Repeat.

Presumably it would eventually kill microbes.
One common means of transforming (aka introducing plasmids) into bacteria is elctroporation, which is essentially zapping bacteria with pulses of electricity. These pulses generate small pores in their membranes, into which plasmid DNA slips in.

However this is done in a highly controlled setting, high intensity bursts, and even that produces holes in their membranes, and even that kills alot of the bacteria. Its assumed that even if only 1% survives, in a culture of >1million cells thats no big deal, you still have 10000 cells that will produce viable colonies.

Now, after that little tangent, electric currents are used as a form of chromotography known as electrophoresis. Essentially when you run DNA or protein gels you separate by size based on charge. Since most molecules in the cell are either negative or positively charged, you would essentially tear the cell apart based on the charge of molecules within it. Even the membrane would be torn apart as the negatively charged head groups are pulled toward the cathode, with basic proteins pulled toward the anode.

HI/red P is nice for intermediate knowledge of chemistry and lab techniques
things like P2P condensation with in situ prepared methylamine reduced over Al/Hg or Grignard reactions for amphetamine are a whole other story. for the more advanced methods you either need huge personal funds, sneaky access to a uni lab or a criminal background

seeing as you dont have any background in chemistry, you should try to opt for the safest methods whenever possible. and id recommend looking up chemistry write ups for practical lab courses in OC1, these often have extensive risk assesment and security information. just to get a feel for proper chemistry and how to take pride in your work

Student here, I'm taking a calculus based physics course and it's ruining my life. Literally spend the whole day, roughly 6-8 hours working on physics problems daily because of the overwhelming amount of work that goes into our grade. To the point that I have been neglecting my other subjects and my grades in those classes are slowly going down, except physics.

My question is, is there any tips or advice on how to juggle such intensive courses and exceed in all of them at the same time? I need to reevaluate my plan because I feel like if I spend less time on physics, my grade will go down since the material is so dense.

Stories of people in higher academia are appreciated. Also tips to unwind and not let physics ruin your life.

For example, I worked on 8 hours of crunching problems in my problem set all day. Now that I'm home, I feel the need to continue but my brain feels like mush.


I take adderall on the weekday and I don't have ADHD, just because I want to pass this class.

Went from eating mushrooms and smoking dmt to willingly let this get injected in my arm. I've been taking it because it seems to make things normal in my waking hours but dreams are questionable. It's listed as having potential fatal side effects while i'm pretty sure DMT and psylocibin don't.

I was wondering if any chemists could speculate on the structural formula to me it looks very large compared to the simple structures of psychedelics, but i've never studied chemistry.

Here's more about the ingredients: Paliperidone palmitate is very slightly soluble in ethanol and methanol, practically insoluble in polyethylene glycol 400 and propylene glycol, and slightly soluble in ethyl acetate.

Invega Sustenna® is available as a white to off-white sterile aqueous extended-release suspension for intramuscular injection in the following dose strengths of paliperidone palmitate (and deliverable volumes of the prefilled syringes): 39 mg (0.25 mL), 78 mg (0.5 mL), 117 mg (0.75 mL), 156 mg (1.0 mL), and 234 mg (1.5 mL). The drug product hydrolyzes to the active moiety, paliperidone, resulting in dose strengths of 25 mg, 50 mg, 75 mg, 100 mg, and 150 mg of paliperidone, respectively. The inactive ingredients are polysorbate 20 (12 mg/mL), polyethylene glycol 4000 (30 mg/mL), citric acid monohydrate (5 mg/mL), disodium hydrogen phosphate anhydrous, sodium dihydrogen phosphate monohydrate, sodium hydroxide, and water for injection.

So what's your opinion should i continue to take it or go back to using psychedelics.

probably cheaper to buy nickel and copper wire and mix them with sulfurous acid, separation of ions is typically done by chromatography, could also try some sort of precipitation reaction to make copper chloride, nickel chloride solids and use the differences in melting points, which would be the least convienent option.

Ni2+ has a standard reduction potential of -0.26V

Cu2+ is at 0.34V

You can selectively plate either metal onto a variety of metal cathodes using a more reactive metal like iron as an anode... I think. You just dial the cell voltage down until only copper is being reduced.

So precipitated by Bombastus I've decided to actually use my brain and time on handling drugs as opposed to just procuring them. I haven't been to school in years and I don't know anything practical about chemistry, just the names of lots of functional groups, not how they work. Anyway, that's just disclaimer.

What I want to talk about is tryptamines, and substituting therein. It was mentioned over in /psy/ that there's a way to convert DMT to 4-HO-DMT. As well as talk of changing 4-subs, to get things like 4-Bromo-DMT and 4-Vinyl-DMT.

I'm not exactly sure what my question is. I think it's a better idea for me to put this thread here and just read what more educated people say to each other. I guess what I want to hear is about how difficult it would be to change substitutions on existing tryptamine material.

Obviously it depends, but since I have no idea what I'm talking about, some examples I'm wondering about:
DMT > another unsubbed tryp, like DPT or MET. What would be entailed?
DMT > 4-HO-DMT or vis versa? I need to get up the gumption to extract DMT anyway; could I convert from there? I suppose that's gotta be easier that extracting alkaloids from mushrooms, separating 4-PO-DMT, from 4-PO-NMT, and modifying from there?
What about 4-AcO-DMT into either 4-HO-DMT or DMT? Working from there could answer a lot of questions about the nature of the 4-AcO-tryps as prodrugs. Also as Bombastus suggested that would make mail order psilocin a possibility.

Anyway, talk. I will do my best to keep up and ask not stupid questions.

I was actually agreeing with you about it not being worth it, despite what you know (accurately) about my 4-sub-MET preference. I guess I phrased it unclearly.

And what do you mean where did I get DPT? Internet. Duh. I had 4-AcO-DPT for a while too, but I didn't get a real sense for it the 2 times I did it. I'd love to have another go at it. Plus DPT is kind of a bitch to dose. I don't intend on touching it again until I either perfect IV technique, or decide to freebase it (which I should really do to gain some confidence about kitchen chemistry);

I've only gotten into the alkyl substituted substances only a few days ago. I took 4-AcO-DET which is the first non-DMT substance I've ever tried. DPT is something to look at for sure, then.
But I think all creations can and should be done with DET instead of DMT considering the stability and relative similarities to DMT molecules.

Why is DPT hard to dose? Can't you just eat it?

Eating it is a massive waste of material, and snorting it is vile beyond anything. Plugging it was far less effective than snorting, also a waste of my money, and injecting it is problematic since it is not wonderfully soluble in water. IM was by far the best route, I just was using several of the 1ml insulin syringes that are easily accesible in US pharmacies.

>Although it was mentioned in TIHKAL that DPT is orally active, we found this route to be quite unpredictable when taking it without an MAOI. Recent reports indicate that propyl-huasca works very well using the standard amount of MAOI combined with 75-150 mg of DPT.

I'm planning to take a senior course on cancer research and do some benign project on cancer as my thesis.

I'm either going to expose cells to carcinogens and see of ways to prevent this, or basically use cancerous cells and see what can inhibit or affect cancer growth with some run-of-the-mill cancer drug unless something interesting is suggested. My uni can get me pretty much anything I want.

Thoughts? I don't want it to be a simple experiment since I'm seriously considering going into the field later and need something that will give me good insight. Signal transduction inhibitors, certain protein overexpression or underexpression, binding to certain proteins that are transported to the plasma membrane?

Anybody have experience with this?

Thanks man. It wasn't a huge impact factor journal because it was just a small manuscript. Not a bad journal but not a great one either.

As for how I picked that protein, well its a critical protein to axonogensis and neurodifferentiation. I did some basic experiments characterizing the effect, made some claims (hypothesizes) about why it was happening, then did mutagenesis on it, as well as used kinase inhibitors to block phosphorylation of the protein. So the original protein and base experiment was given to me and I ran with it. Was solid at the end though.

That is cool that you are working with astrocytoma, astrocytes being something that I am quite familiar with. Best way to figure out a target is to read papers, and when you get a good idea of the landscape as to what is known, start writing down questions.
If you can find the answer to that question somewhere, cross it off. If search generates no leads, keep it as a possible avenue. But don't go for the thing with nothing known about it right off the bat. Too risky, its a total gamble and you don't want to waste 6 months only to find out your research is fruitless. Save that for a Phd student who has that kind of time. Start with something that may have been confirmed to have a role but it is not entirely characterized, and think of ways to design experiments to further characterize its role. Have a list of them and try a bunch, because more than a few will not work for specific reasons and nuances related to that protein.

That make sense?

You could do an experiment where you treat cells with sulforaphane (a plant extract with histone deacetylase inhibitor activity) in the presence or absence of a methyl donor (like vitamin B12 or SAM) that could push the system in one direction or the other by adding extra substrate for changes in DNA methylation. http://www.ncbi.nlm.nih.gov/pubmed/26703571

That's a pretty solid idea. Not too complicated, just need to make sure he orders folate/B12 and SAMe deficient media so he can control the dose.

>A sandwich is a food item consisting of one or more types of food, such as vegetables, sliced cheese or meat, placed on or between slices of bread, or more generally any dish wherein two or more pieces of bread serve as a container or wrapper for some other food.[1][2][3] The sandwich was originally a portable food item or finger food which began to be popular in the Western World. Today sandwiches in various versions are found worldwide.

>Sandwiches are a popular type of lunch food, taken to work, school, or picnics to be eaten as part of a packed lunch. The bread can be used plain, or it can be coated with one or more condiments such as mayonnaise or mustard to enhance the flavours and texture. As well as being homemade, sandwiches are also widely sold in restaurants and cafes, and are sometimes served hot as well as cold.[4][5] There are both savoury sandwiches, such as deli meat sandwiches, and sweet sandwiches, such as a peanut butter and jelly sandwich.

>The sandwich is considered to be the namesake of John Montagu, 4th Earl of Sandwich, because of the claim that he was the eponymous inventor of this food combination.[6][7] The Wall Street Journal has described it as Britain's "biggest contribution to gastronomy".[8]

Is it visible without anything to reflect off of and if you cannot see the source of it? I'm in a room lit only by the computer monitor, waiting for someone by my open window at night and the thought just randomly occurred to me and I thought I'd hear your guys' thoughts on the subject.

light bounces off a lot of shit: walls, cloth, air, etc. the last one not so much but try the experiment at home.
go to a windowless room, turn the light off and just practice with a small, dim fleashlight

even if you could violate the laws of physics to do this you would still need to do it in an environment free from gravity and close off the sides to prevent erratic protons escaping and the mirror would have to be a perfectly smooth surface of quarks gluons or some other subatomic particle and even still entropy would eventually cause the protons to just slow down oh god why am i even bothering

or just ya know, use a half reflective plate that way some light passes through anyway

Not so fast!
This isn't completely wrong.
If you could build a box out of PERFECT mirrors
If you could keep the mirrored box from losing ANY energy over time...
then following troll's procedure would result in
the input light bouncing around ~forever
However, you could never use the light for anything for anything or observe it, since doing so would consume the meager amount of energy stored by the endlessly reflecting photons.
There is an electromagnetic component to this as well, but I'm pretty sure that a PERFECT mirror keeps reflected radiation from losing energy due to electric or magnetic forces.
Given, perfect mirrors don't exist, and likely never will... however with really fucking good mirrors you could get the light to hang around for longer.
Cooling the entire setup to nutsack shattering levels would help with duration as well.
