Zika Virus: Is it an ELE? by Nell Snodstock - Sun, 28 Aug 2016 17:35:29 EST ID:5UnrR+r2 No.78188 Ignore Report Reply Quick Reply

I just had an interesting short chat with a store clerk of a quickie-mart type of place. What he said actually freaked me out. He said that Zika reached our area (Florida) and how it'll take a month before money is released to try to combat the problem. But this wasn't the interesting bit, the interesting bit was him saying: "This is bad because mothers can't have babies. Without babies, we will go extinct; an extinction level event (ELE)." It was one of those moments that it didn't strike me just how dangerous Zika is to the human race. I saw it similar to the Ebola scare we had.

I hoped to him that perhaps science will solve the issue. He replied by saying we aren't exactly Star Trek level so you never know.

It could be that as a store clerk he is searching for something exciting because life as a store clerk is anything but. It could also be a covert-Christian trying to prolysetize. So science-peeeps that may be reading this, set me straight. Why shouldn't I worry about this problem, at least not overly so?

I am sure that I am missing something that makes this problem not as major as the store Clerk made it out to be but don't know where to start. Couldn't we simply make a vaccination? Couldn't we, in the worst possible event, simply do in-vitro fertilization in which the child has a natural immunity to the virus?

What could we do? This is actually scaring me.

Thought you were quoting Game of Thrones for a moment there.

Are adults ok? I heard about the blood-brain barrier and how because of this barrier can't affect an adult brain. Is this true? I read an article stating that this may not be true and can cause alzheimers or other conditions.

Do you think the CDC or some organization can do a good job on this issue?

It's currently gridlocked to the areas around the equator that have egypti and other tropical mosquito species in terms of mosquito transmission.

The bigger issue is that it's sexually transmitted. I think the main vector is going to be humans. As long as it's still a popular trendy scary disease and the people who have it are on lockdown then it won't spread far enough for the kind of damage you're talking about. I think a vaccine is in the works but who knows.

I found a great free molecular simulator, at http://avogadro.cc/wiki/Main_Page . It's real easy to use, but the fucking thing crashes without warning or apparent reason. There's seemingly nothing I can do to make it run. The only circumstance it DOESN'T crash in is when I first load it and haven't added any atoms/loaded a save.

So unless y'all have a fix that I haven't tried, I'm looking for a program with a similar sandbox-style modeling.

Could you elaborate on what computing resources it takes/what gives you the most mileage? I'm buying a new laptop soon and would like to start playing with frontier orbitals, docking, ADME modeling, etc.

If a decent graphics card can speed these computations, that's a real plus.

I'm not too familiar with molecular modelling, but I know it uses similar computations as neural networks. That is, it's mostly linear algebra, and having a good graphics card is very useful. In the NN world, an NVIDIA chipset will get you much further because it understands CUDA instructions. On the other hand, AMD chipsets use OpenCL, which is less supported. Last time I tried out modelling software (5 years ago), this was also the case. So I would look for a laptop with NVIDIA graphics... Except I've also read bad reviews about NVIDIA shit in laptops. Maybe that's old, or linux-specific, but be sure to check out reviews.

I sincerely doubt you'll be able to do any modelling on a laptop under $3k. On the other hand, you could probably build a PC with a lower midrange graphics card for $600 that could outperform the $3k laptop.

Man I was having such a good day today at work.

There I was, being all kickass at my job, and SOMEHOW the topics of organics and GMOS came up. I am so for GMOs its not even funny - organics, hey, but what you want but don't try to take away my options. Also, don't tell starving kids in India what to eat while they're dying? Follow those two rules and all will be well.

Man, I had no idea. These are people who work for the government, and it was liked I whipped out a baby and started to slaughter it in front of them. I didn't state my opinion, I just appeared neutral, but I was angry inside. How can these people profess for being about knowledge and the cutting edge, but believe that pesticides don't wash off of food? And that " We don't know enough about it to eat it" while eating cheese?! In front of me?!

I'm still mad, and have to go back to work tomorrow. I hate being a pot smoking skeptic sometimes, I feel like a damn unicorn.

You know what the GMO labeling thing did to crop markets in European nations? It caused consumers to falsely believe that if a food product had a GMO label that it proves that it was bad despite it passing all the oridinary inspections and reguiations nations enact. You know who were the bad guys in this? It wasn't GMO corps. It was so-called "small farmers" tactic to destroy their competition while at the same time charge much more for the same exact food. Making a bundle on peoples gullibility. The big evil corporation here is the "organic" market fooling people into paying more for the same product. Good job ya dunce.

Don't forget that companies like Monsanto are completely happy with the current GMO hate.

It just means that they have a monopoly position, because Monsanto can just set up an experimental farm in South-America and protect it with armed guards, while starting GMO companies have to do their experimental farms in the Western world and have fucking anti-GMO protesters (that may or may not be funded by Monsanto and other big companies) with bulldozers trashing their farms and send fucking bombs, bullet letters and mysterious powders to personnel and geneticists. Hell, people just doing research at universities without any profit gaining are getting death threats.

Not true, if you wash the soxhlet before using it (and i mean really wash it), you can use it as a distillation apparatus if you pour out the solvent before it reaches the siphon tube.

It's ghetto as fuck but can work to save you $150 on a distillation condenser and adapter.

So this might be more semantic than scientific but I wanted your guys thoughts on the matter,

So hypothetically, if we did find life from another world, life evolved from a completely independent source than ours, and even if it was animate, easily recognizable life, maybe even humanoid...

It still couldn't technically be an animal or any of our kingdoms/domains of life, right? Like, when we're talking about the various domains and kingdoms of life, it's kind of implied those can only be terrestrial in origin since we're talking about a tree of life with a common ancestry right? Like if we got an Earth fungus to grow on another planet and it evolved into a new species of fungus to better live on that world, it would still be a fungus because it's ancestors were Earth fungi. But if a life form from somewhere in space from a completely different line of evolution were to travel to earth, even if it coincidentally shared a lot of similar traits to Earth fungi due to functional convergent evolution, it still could never be considered kingdom: fungi right?

tlIf do we sort alien life forms by phenotype traits or genotype ones?

Dearest /chem/,

I wish I were one of you, but I'm not. My knowledge of chemistry trivia might impress at some parties but when actual questions arise, assistance is necessary. I was hoping you could help me estimate the relative potency of cyclopentyl-fentanyl, a novel fentanyl analogue. You will find It's structure displayed in the picture.

My thoughts: Cyclopentyl-F seems to be structurally related to Acryl-F. The latter is said to be active at doses <10 mcg. But on the other hand, cyclopentyl-F also seems related to Acetyl-F which is said to only be 1/20th the potency of regular fentanyl.

Thank you for your time.

With most of this shit, you simply can't look at the molecule and guess its relative potency, unfortunately. This is just the reality of biological assays and why they are necessary.

Organic chemistry is simple to estimate but biochemistry requires in depth knowledge of all the enzyme sites around your receptors which can lead to potency changes. This is near impossible to do without high computational machines or more accurately: petri dish bio assays.

Sorry to burst your bubble, Sarringberk.

Recently in the CWE thread someone was asking for book recommendations on chemistry textbooks, and the rest, and Press uploaded a couple of image-rars. I've been thinking we could benefit from our own central thread where we can discuss our collections, what we're reading, with an organic chemistry/synthesis theme. I know they have a good recommendation list at the /sci/ wiki over on the future, but fuck the future. This is /chem/ and we are a proud people. Also, we have a smaller community centered more around org-chem and synthesis, so it's a niche this thread should fill with more in-depth recommendations on the subject, and the provision of papers and other supplemental material.

To anyone looking for books, I'd recommend libgen. I only recently discovered it and I'm quite frankly relieved at not having to scour torrent sites and the awkward interface of #bookz for hours on end only to discover a rare book I'm looking for isn't being seeded.

I recently got Alan F Casy's Opioid Analgesics: Chemistry and Receptors off it, which I'd actually considering buying for about 50 euro used half a year ago. What a travesty that would have been. So far I've only checked out the chapter on 4-phenylpiperidines, but so far it's an interesting read. I used to have a better collection on my old computer but it crapped out, and here's what I'm working with at the moment while I rebuild it. I'm an undergrad, so I assume some of the more seasoned veterans here will have comprehensive collections.

Alright, well if you have that much money, you might as well extract all your seeds with a slightly acidic solution, rinse with hexanes, basify with CaOH and NHx, and filter that off. This way, you're working with all liquids and the rotovap makes everything much easier. The washing of the seeds will be the hardest part.

propanethiol and butanethiol can be smelled when in its airtight glass bottle, vacuum sealed-foil lined bag, inside of a ziplock bag coated with chemical absorbant, all while sealed in a stainless steel can. as you surpass these layers of protection, the smell gets worse and worse.
A reflux condenser is absolute suicide.
humans can smell ethanethiol at concentrations of 4ppb. i think i had propanethiol at at least 500ppm when i opened it to the atomosphere

eu not that bad. go to UK and buy a bunch of dihydrocodeine or regular codeine pills. or get someone else to do it. iunno. that seems legal. call them herbal supplemtns or calcium pills or some fucking shit

that looks promising, actually. i'll take an extra look into J. Magano et al.'s usage of 2-(Diethylamino)ethanethiol. that looks much better and more stable than fucking propane-fucking-thiol. thank god the thiols aren't toxic.

No in the molecule. I still can't see the difference and it's NOT in chirality.
