Yes, like StringJunky said, the hormone may be denatured, or the satiety hormone that is released when the chyme enters the small intestine may only be a small amount. Yes, the hormone is released, but it may be an insufficient amount, or possibly some kind of delay is involved in which the satiety is only short lived.

The trans-trans product will be majority/ most abundant product because it is more stable. However there will always be minor products as well due to "adequate" energy conditions and certain bonding angles that happen to form bonds just right..that being said your professor is correct to say that the trans-trans product is found exclusively by itself, or at least with some cis-trans product present. This because the trans-trans and cis-trans product likely makes up more than 97-99% with < 2% to 1% being the cis-cis minor products. At the < 2% to 1% range is it helpful or even necessary to pay attention to the "other" products that were formed? Yes, they're there...but mostly irrelevant. As far as differentiating the products, you'd have to separate therm..im guessing chiral chromatography or diasteremoization?

I just finished by BSc in biotech. I currently do research for a diagnostics company. I can say for sure that bioinformatics is an great field to get into, especially with the growing interest in data science. I had a friend who started in biotech and then moved over into bioinformatics. You're going to want to get more into computer knowledge rather biological, as your biotech degree will cover most of that. Specifically, I would suggest getting started in numerical analysis, data structures, data science, specific statistical programs, etc. Go into a book store (Barnes & Noble), and just grab book and a coffee and read for an hour or two. Don't bother looking online for this stuff, excpect for really basic, intro material. If you want an in-depth look, try a few books on the topic.

I took calculus I back in college, but never needed to take calc. II or III. I'm a little interested in learning II and III, just for general knowledge and boredom, but I don't want to spend in-depth analysis with the actual math questions and such. Since I have general knowledge of calculus, is it possible to get a general idea of how calc. II and III operates with just graphical examples? ~EE

Two strong bands in the 1345-1580 range sure sounds alot like a nitro group. I would run a second experiment, with similar conditions, except use a catalyst for the HP degradation, and then look for confirming results. The study below answers your question, but it doesn't provide any details of the experiment. https://www.ncbi.nlm.nih.gov/pubmed/14653685

I never knew these existed. Answered my question, thanks! Touche.

Mammals with excess adipose tissue are described as fat. Really, being overweight and/or obese is just a metabolic deficit, in which glycogen and triglycerides aren't being sufficiently used for energy. Overtime they build up in adipose cells, therefore increasing mass. Can the same thing happen to plants? Reduce the usage of a particular energy dense molecule, and instead just build it up in supply..therefore increasing mass? Perhaps obtain "excess" CO2? ~EE

As far selecting specific bacterial strains, this can be done with different growth medias that certain bacteria will grow on. Once the selective bacteria starts to grow, help it proliferate with more media, nutrients, etc. For example, Mannitol salt agar media is selective for Gram positive bacteria.

No I'm talking about former addicts, who've been off the stuff for years. Get as much internal info as possible.

The former. My thought is to hear what former addicts have to say, how they got it, where they got it, etc. More than anything else, the spree of overdoses we've seen in Buffalo has been caused by heroin being laced with fentanyl (it is primarily an opiate problem as you explained). I know it sounds terribly cruel, but what if narcan were restricted from being used? From what I've heard is that the narcan is somewhat enabling abusers. If the customer base dries up, there won't be any drugs. That's at least my sentiment, and I know removing narcan won't be an attractive idea.

What is it that you are trying to do?

I never took the time to notice that you lived in St. Catherines, ON. until you mentioned Canada. I live 10 minutes outside Buffalo, NY., and I regularly go to lewiston, NY and Old Fort Niagara..howdie neighbor! I bet you've heard about the terrible opiate issue here in Buffalo though. I've lost 5 people from my high school graduating high school class of 2011..all in about 3 years after graduation. and that's just one town..much worse in the city. I had no idea Ontario was having issues too. I liked some of the suggestions of getting info from abusers, and their take on the situation..how they got started, where the got, etc. All excellent responses folks!

The topic of the discussion is addressing a terrible opiate epidemic that has struck my city...as with many cities in the US in the last couple of years. I'm open for suggestions any of you have that I can provide at this discussion. ~EE

Acid washed jeans are faded because the acid reacts with the specific dye in the fabric. The reaction alters its "conformation" (lack of a better word), and causes it to lose its color property. hope this helps.

So the company I've been working at has been wearing me down. I recently graduated college in May with a BS in Biotechnology, and started my first job in June. Still working at the same company. My company makes point-of-care kits for infectious diseases..nothing cutting edge. I work with several scientists as my job is R&D. I don't know if it's the private industry or whatever, but the people I work with seem to shrug any kind of science off their shoulders. Trying to go deep into thinking to solve a problem is quickly dismissed with "it's not my job/ we don't do that here", or no solutions are really investigated...just make the product "work" enough. Any on the spot science confab is quickly dismissed with a one word response or clear disinterest. My co workers seem very reserved and calculating (as I've been told what the corporate culture does to you). I'm convinced these "scientists" I'm working with only got jobs in their field because they thought it was going to be goods money or decent job security. Instead of real science talk, all these hacks talk about is work-politics, work related grievances, and how inefficient the company is run. Everyone is too busy making political alliances with higher ups (going out to dinner, sucking up), and trying to elevate their job title to "blank" manager. It sickens me. I used to work in a uni research lab, and I LOVED it because there was constant exchange of ideas and real thought processed as play. My PI loved his work and tried to expand what he knew about his project. There was never any discourse of politics and getting the upper hand. I swear my co workers are only there for a pay check. Have any of you come across something similar to this in your careers? Is academia/ public research vastly different from private industry? ~EE

But then it wouldn't matter if it were 0 C or -50 C, the water would freeze regardless of temperature. I'm assuming that water molecules create a stronger H-bond with each other in an ice lattice than with the OH groups attached to the 3 carbon chain..because isn't the glycerol slightly more non-polar than water? Much like how isopropyl alcohol is more non-polar than methanol because of the 3 carbon chain. My thought is, the colder it gets, the higher the chances the water molecules form a stronger hydrogen bond, meanwhile the glycerol just kind of flows around them...similar to a size exclusion chromatography column.

Well in the case of charged ions, no. But I ma referring to larger molecules, like glycerol, and ethylene glycol that would wedge their way in between water-water interactions.

I know that glycerol, anti-freeze, and salt can be added to water to depress it's freezing point. These substances essentially interfere with hydrogen bonds between water molecules, so there isn't any lattice crystal structure being formed. But when the temperature gets cold enough, the water does eventually freeze/ form lattice structures. My question though, is HOW? There's literally a molecule blocking adjacent water molecules from interacting, so how does a lattice structure still form? ~EE

The double slit experiment was done to show an example of quantum mechanics (i.e. particle-wave duality). E=mc2 is a relationship between mass and energy.

Let me one up you. Drone + C4...you don't have to die on the first floor anymore.

It's pretty much the same concept...is it just that microarray's are high-through put and ELISA's are just less sample abundant? I don't see how a microarray could be more efficient in the theoretical sense (bind a protein to a surface, and react with antibody, conjugated anti-body, and measure signal). Perhaps in the volume sense of the number of samples, but I don't really see anything else. Am I missing something here? ~EE

(a) sounds correct. The HCl is donating a proton, which is what a Lowry-Bronsted acid is defined to do.

I don't think the fish were actually "frozen"...at least not the arctic fish. The rainbow smelt (arctic fish) produces glycerol, which depresses the freezing point of the water in it's body. So it could feel/look frozen, but no actual ice crystals forming.

Ok, so I see in some parts, my statement is lacking and confusing. I was trying to make a shorthand post, rather than a TL;DR post. Guess, we're going the long route then. So, it's generally regarded that finding a well paying, steady job as an actor, artist, musician etc is fairly difficult, hence the "starving artist". All other regular 9-5 jobs, such as accountants, engineers, lawyers, doctors, etc, are well paying, steady jobs. However, when we reach an age of major scientific advancement in fields of engineering, medicine, computers...alot of these jobs will go away because there will be no use for them. If you think about it, alot of jobs in society are there because of scientific advancements one way or another. We mechanics because en engineer built a car, we have computer scientists, and IT jobs because computer scientists built computers. Doctors, nurses, specialists, etc exist because scientists made advancements in medicine. Also, other non-science related jobs are made because of these advancements. Customer service rep's are needed in IT companies, secretaries are needed by doctors, cashiers are needed in mechanic shops, quality control specialists are needed in Pharma companies. Salesmen are needed to sell drugs and cars. Manufacturing tech's are needed in engineering companies..etc. More or less, alot of trickle down jobs are made because of scientific advancements. Most of these jobs are consistent, decent paying jobs. In contrast, an artist doesn't always have a consistent paycheck or customer to support them. The irony that I see in this is, if/when we reach a time when EVERYTHING is automated and made perfectly efficient, that there is no need for janitors, salesmen, accountants, IT customer service, QC specialists, nurses, doctors, engineers. The jobs that will have the same prestige and demand that an engineer or doctor accrue will be artists. Automation can't replace actors, comedians, writers, or musicians. Sure, you can make electronic music, and use CGI for movies, but the few "people" that have these jobs would dominate the job market. btw, im not an engineer. My name is from the video game, Dead Space 2

I think we're half way to reaching this inflection point. The time when we have 100% energy efficiency, 100% of diseases cured, 100% automation, 100% food production, 100% technical transparency, 100% repair..there will be no jobs for scientists, doctors, cooks, mechanics, specialists, designers, engineers, secretaries, developers, financial planners. Artists, actors, musicians, the whole lot will become the doctor and lawyer of yesterday. Science will become a thing of the past, an archaic method that has no purposeful application, barely enough for "education". I feel like we're beginning to feel the early stages of this, with smart phones, and other technologies and their connection with Twitter, Netflix, etc. I suppose it's akin to 1984, but just bare with me. Your thoughts? ~EE
