Oh. My. God.
I bet that bench is really unstable.
I don’t usually like voicing my opinion, because normally, I don’t have a very strong one, I’m very tolerant and adaptable I’d like to believe. However, I DO get really riled up when people spread scare images on the internet about incorrect scientific facts.
One of my facebook friends posted this and I got really frustrated and wrote a reply.
*cough* sorry I have to interject because science and people should know more about the things they spread around the internet to confuse the populous. The Bt-added GMO corn produces a protein called delta-endotoxin/toxic crystals protects the plants from being devoured by mosquitos by rupturing the stomachs of insects, yes. This is because insect stomachs have ALKALINE lining, which denatures the the insoluble crystals, making them soluble and thus able to being cut with proteases found in the insect gut, releasing the toxin.The toxin is then inserted into the insect gut cell membrane, forming a hole. The pore results in cell lysis and eventual death of the insect. OUR STOMACHS, though, have an ACIDIC interior and a mucous lining, which the endotoxin does not react to at all. There has been no known instance of the endotoxin having adverse toxic or allergic effects in humans, and although this “warning” says it’s in pregnant women, it’s not going to harm the mother or the baby. If there are any health problems that have occurred, they are few and far between. The study done on rats was found to be a hoax, by the way.

And then Some other people responded like:
1.Oh god, monsanto’s. We learned about all this in my Environmental Sustainability class. Not only is that an issue, but over time, the chemicals mutate the bugs and create super bugs believe it or not!
2.While I COMPLETELY with what you said and know it to be true, it took me a minute to shake the smug off what you said, which for ME makes YOU sound LESS intelligent than what I’d guess you actually are. It also doesn’t help the truth to spread and get absorbed. Of which both would seem like intentions and objectives that you began with. STaY_K3WL_d00d
I replied to the first comment with:
If you wanted to know… the mutation issue is with the resistance of the bugs to the toxin. So the toxin kills all the regular bugs, but many bugs are adapting to the pesticide and naturally mutate (just like all organisms), and ones who have the right breeding of toxin resistance end up surviving. Just like with overuse of antibiotics in our society, there are many bacteria that get killed but anti-biotic resistant bacteria survive and multiply. Monsanto’s isn’t too bad…but it is still a big company who’s goal isn’t environment but about profit, so many of the products they make have a lot of environmental consequences like toxin-resistance or patent problems… it’s pretty upsetting. :(
The smugness comment was really confusing and kinda took me aback, but I apologized for sounding smug….. I wasn’t trying to be smug, I was trying to be as informative as I could. ._. This sort of misinformation really really bothers me because people who don’t do their own research on this sort of stuff become really scared and spread this news around. And it isn’t always true! And this sort of spread of misinformation is BAD BAD BADABDABDBSBAD. PEOPLE NEED TO USE THE INTERNET TO GET A SECOND OPINION/MORE INFORMATION ON THINGS, not just listening to the first rumor or picture message they see. This sort of scare results in people not buying from certain companies, or refusing to eat certain foods…. for no reason, really. :(((((
Augh I just hate being “that person” when it comes to these things…. but I know the science about this stuff it’s so hard to not correct people aughgkjhrowqiqpoe.
Get it because it’s a CELL WALL
WOW THAT’S GOOD
this is what i do for a living. i will explain at length below. disclaimer: the following will likely bore some of you. others may enjoy it.
this is a heatmap of tissue-specific microarray probes i’ve found in the pacific salmon. each microarray probe corresponds to a gene (roughly), and through a fairly complicated process that i won’t explain here, the microarray probes allow a measure of gene expression in biological samples. you should think of the image as a matrix of data where numbers are represented as colors. each row corresponds to a single probe, and each column for a single tissue sample. (so the color at any given spot on the heatmap corresponds to the level of gene expression for that probe in that sample). bright yellow means lots of expression. the darker the yellow gets, the less expression there is.
you can see four main sort of divisions in the heatmap, these correspond, from left to right, to the brain, gill, liver, and muscle samples on the microarray.
the analysis of the genes corresponding to the probes on this heatmap will form the basis of a paper i am writing. no one has looked globally at gene expression in the pacific salmon before, so the paper will be useful for other people who want to study salmon in the pacific.
this was a fairly technical thing i’ve tried to explain here, so sorry if it makes no sense.
