while I’m here:

  • aspartame does not give you cancer
  • gluten is not bad for you if you’re not allergic/don’t have celiac disease
  • superfoods aren’t real, they’re just healthy things with maybe some nicer levels of certain vitamins
  • vaccines do not cause autism or really anything else and the chemicals present in them that typically scare you are in such minute amounts that they do precisely fuck-all in your body (we’re talking scales of one part per million)
  • you cannot do a cleanse or diet to “rid your body of toxins,” your kidneys and liver have that covered
  • GMO foods will not kill you; most genetic crop modification just makes our crops hardier and produce more food (and genetic modification doesn’t inject more chemicals into your food, it’s just minor altering of DNA that is made of the exact same stuff your DNA is made from)
  • if you feed your cat a vegan diet I will personally come to your home with the skull of a long-dead predator, point out the shape of its jaw and teeth as indicators of predatory feeding habits, and then beat you with it

I love this

Okay, so I went through the tags and a bunch of people are saying-all of this but the gmos…they’re still evil. So glad they’re highly/regulated or banned, or I hope they’re highly regulated and banned. Never buy gmos, etc. 

Plant scientist here: 

OP is on the money. GMOs are NOT(and I have heard LITERALLY every one of these): radioactive, injections of chemicals, or producing DDT. It is a modification of DNA to improve the crop in some way that farmers find useful.

In fact, technically speaking, all crops are GMOs. Ya know why? Because ever since humans started growing plants they wanted better plants and so they “genetically modified” them by breeding. Want an example? This is a graphic of teosinte, the ancestor of corn, and corn(maize).

Anybody want to have some teosinte at their next barbecue? I didn’t think so. 

What governments (and the general populace) term GMOs are organisms that have had their DNA modified in specific ways through the use of biotechnology. This typically leaves some random fragments of DNA scattered in the genome (and plant breeders are required to idenify them and where they are) and the desired insertion, which usually consists of a cauliflower virus promoter, several antibiotic/herbicide resistance genes (these are for selection purposes and are for really rare antibiotics/herbicides) and the desired gene. The exact construct is known-and you can see it too.

The most common gene insertions are for several herbicide resistance genes (Roundup being the most famous) and Bt. Bt is a protein toxic to insects. It affects the peritrophic membrane. Now, you as a human, do not have a peritrophic membrane, nor do you have the required pH in your gut to even have the protein fold correctly. Also, organic farmers regularly spray this same toxin all over their crops-the only difference is that the GMO plant produces it. If you are an insect-like alien-you’d better not eat our food.

Does BT adversely affect monarchs? Yes the variety in question did….and it was pulled from the market. The varieties currently marketed contain different versions of the protein.

“Ahhhhh I am scared because there are all these antibiotic resistance genes and virus genes in my food.” First of all, the studies claiming these were harmful are scientifically invalid due to their experimental design (seriously, the screwed with so many commonly used protocols its ridiculous). Second, plant breeders don’t like the extra genes anymore than you do. The newest research in the field uses CRISPR-Cas or TALEN genome editing technology which allows us to only edit/insert the genes we want. This makes the regulatory process easier and makes us happier because the end result is neater. 

Lastly, “Companies won’t let farmers save seed.” I will get into this later (because a related issue is a real issue with GMOs) but I have info for you. Most farmers don’t save seed anyway.  This is because almost all commercial farmers grow hybrids. Hybrids are crosses between two different inbred lines. Farmers grow them because they have something we call heterosis or hybrid vigor-this means they grow better and yield better than their parents. Unfortunately, due to the laws of segregation, the plant children of hybrids are not like their parents. They are weird, and weird in farmer terms equals unprofitable and why would I grow that crap. So no, farmers ain’t gonna save their seed anyway.

Now, what are the real issues with GMOs? Because I’m not going to pretend there aren’t some. 

IMO the biggest issue with GMOs is that they (and their genes-which is even scarier) are controlled by a few big companies. This means two things-one the big companies dictate what farmers can and can’t do with the seed (and occasionally prosecute people they shouldn’t) and have a scary amount of control over the plant genomes and two, interesting and possibly more beneficial research doesn’t get done because the company is interested in profit. 

But, you know what doesn’t help this issue? MORE REGULATION. The more you regulate GMOs the more you will force ONLY companies like Monsanto to do GMO research, because only they will be able to force their varieties through the regulatory hoops. Public and open source genetic manipulation of more agronomically useful traits could help the organic movement by giving it the plant variety tools it needs to get better yields. This is not possible when regulations are extremely tight.

The second issue is one of pest resistance. Pest resistance to herbicides (plant pests) and BT (insect pests) is an issue with GMO crops…but its not unique to GMO crops either. Conventional crops encounter exactly the same issues-its why we need plant breeding-because its a constant race against the continuing evolution of pests. IPM can help these issues…but it alone can’t solve them. Only breeding can do that.

Also, in regards to “Don’t buy GMOs” good luck with that if you’re in the US. Literally every product that isn’t organic and contains either soy or corn (which also includes stuff like soy lechithin and dextrose that’s in most foods) is GMO. Do you know why? Because farmers like to grow what makes them money, and, currently, growing GMOs increases their yields and decreases their pesticide costs so much so that the profits from their crops are worth the increased seed cost. They are making money from GM-otherwise they wouldn’t grow it.

This has been your GMO psa.

Okay but no, do you understand what happens to a caterpillar once it’s in its cocoon? It completely turns into goo. That’s right, GOO. The damn thing dissolves and the reforms into the butterfly. Even crazier, the wings of the butterfly are already inside the caterpillar, ready to go, just waiting to float around in some goo and then be a beautiful butterfly. The craziest part?!? A study was done where some caterpillars were exposed to a certain smell and then given an electric shock so eventually the caterpillar associated the smell with the shock. Well after those little hairy noodles came out of the their cocoons as butterflies, they exposed them to the smell again and the butterflies reacted super negatively, as if they were being shocked. A.K.A. not only is there wings floating around in that goo cocoon, there is also a brain, the same, unaltered brain as the caterpillar. The butterfly can recall its days as a caterpillar even after basically being turned into soup. And then it all somehow gets its shit together to be a stupid majestic little beast, and I can’t even remember where I put my damn phone.

fun fact: if a persons body odor smells good to you that means they have an immune system basically opposite of yours! this happens so the chances of finding a mate with the opposite immune system is greater and the chances that any offspring you produce together will have a stronger immune system is greater.

this is fascinating

so you’re saying deodorant is the reason none of us can find love

No, but this is exactly why Freddy is so amazing. He’s an ordinary person. Although he’s wealthy, he never mentioned it. He never treated anyone differently because of his monetary status, because never considered it an important or defining characteristic. And although you’d think he’d be insecure about hanging out with a bunch of geniuses, he’s never afraid to be himself. His personality is completely unassuming and he treats everyone equally, regardless of gender, IQ, money, or race. Not only that, he also pursues his dreams without letting anyone else put him down for it. How great is that?

And then he went and kicked ass with the best of them, proving that anyone can be a hero— that just because you are ordinary doesn’t mean you can’t do something extraordinary.

A Clitoris is actually an undeveloped penis; since we all, at some point, are both male and female in the uterus, before the dominant gene takes over, the penis on a female and a male is actually the same. And once the dominate gene takes over for a male, the clit actually develops into a penis, so technically, when a girl says: suck my dick… I guess it’s kinda politically correct…

brassholes:

Actually female is the default genetic setting so penises are just giant grotesque clitorises.

A graduate student has created the first man-made biological leaf. It absorbs water and carbon dioxide to produce oxygen just like a plant. He did this by suspending chloroplasts in a mixture made out of silk protein. He believed it can be used for many things but the most striking one is the thought that it could be used for long distance space travel. Plants do not grow in space, but this synthetic material can be used to produce oxygen in a hostile environment. (Video)

If you don’t think this is cool, you are very wrong.

If something is ‘old as fuck’ then it’s about 1.2 billion years old because that’s when life evolved sexual reproduction.

 

However, if something is “old as balls” it’s only about 65 million years old, when placental mammals began to evolve proper testicles.

The real problem with people fussing over Pluto all the time is it represents the priorities of the public - preserving traditions rather than accepting facts. The pursuit of science is about building a sustainable catalog of truths, and there is no advantage in altering truths to appease nostalgia.

Why is it that wet hair is darker, if water is colorless?

sodamnrelatable:

crowleys-angel:

Reflection.

Because water reflects less light than air does, due to it’s molecular make-up. Thus, as hair is covered with a layer of water, the light isn’t reflected the same way, appearing darker.

shakespeareintellectualbadass:

Thank you, science intellectual badasses

ink-splotch:

Also water is not colorless.

Pure water is very very slightly blue, so slightly this is apparent only when looking through very large quantities of water. Which doesn’t have any impact on the hair question, but it’s a fun fact.

I know a NASA engineer who got into a big argument about it with a Russian scientist who was sure that the tank of water they were testing their space suit design in had to be contaminated, as it looked slightly blue
