GMOs

The environmental benefits of genetically modified crops is explored in Conservation Tillage, Herbicide Use, and Genetically Engineered Crops in the United States: The Case of Soybeans

A piece on the claim that GMOs are under-studied, With 2000+ global studies affirming safety, GM foods among most analyzed subjects in science pretty much demonstrates that no, they are not.

Neonicotinoid pesticides are sprayed on crops, and they are bad for good insects. But they’re good for selling plants. Engineered pest resistance doesn’t get sprayed and affects only pests that attack the specific crops. Just sayin’.

Organic foods may have been sprayed with pesticides, too – and isn’t necessarily any better for you. Being free of GMOs makes no difference.

Vaccines

A friend and I were blocked from commenting on an online discussion on the terrible, horrible things that are vaccines. This is a typical technique of anti-vaxxers. A detailed description of what it means to be anti-vaccine is on Science-Based Medicine It’s from 2010, but classics never get old.

Because of a new study analyzing the actual risks of vaccination (hint – nearly none, even less compared with disease outcomes) the pro-vaccine message is finally getting the press it deserves. USA Today, The Daily Beast, Think Progress (I know, not a big anti-vaxxer magnet) The New York Times and Time. Even The Economist reminds us that we should take our medical advice from science, not celebrities.

Medicine

Viruses may be responsible for several cancers. The Big Idea That Might Beat Cancer and Cut Health-Care Costs by 80 Percent explores a virus that may trigger certain kinds. Vaccination to prevent cancer might work better than treating it after the fact, ya think?

This is stupid, which means it made me laugh a lot.

Debunking!

In the wake of pretty much every outbreak of every vaccine-preventable disease, comments on the news articles fill up with people who still think that vaccines cause autism. One article keeps getting referred to, “22 Studies that Prove Vaccines Cause Autism.” I’m not going to link, it doesn’t need any more hits, because it already shows up on the first page of many searches on vaccines. Instead, I’m going to direct you to Liz Ditz’s excellent rebuttal.

Foodbabe proves over and over that she’s all style and no substance. The Foodentists dissect her attack on Lean Cuisine and the Grocery Manufacturers Association with many facts about GMOs that she apparently doesn’t know – or chooses to ignore.

On the topic of GMOs, Gilles-Eric Séralini’s paper linking glyphosate to tumors in rats, which was retracted last year because of methodological and statistical flaws, has been re-published in a journal with apparently less exacting standards. I’m thinking along the lines of “repeat a lie often enough and it becomes the truth.”

SFARI tells us that autism is not the only neurodevelopmental disorder that’s on the rise. The numbers may actually be a good thing, because it means that more people are getting needed treatment.

You know that study that said watching porn shrinks your brain? Well, maybe not so much. Christian Jarrett at Wired talks about the study’s many shortcomings.

Business Insider has an interesting piece on the Myers-Briggs personality test. By the way, I’m ENFP.

Sometimes things are partly true, or true but misrepresented. In those cases, we don’t need debunking, we need. . .

Critical Thinking

I got a little gut-punch here, because I hate neuroscience hype, but I also did a few little happy dances reading about optogenetics. I pick on optogenetics, but… and Moving on from optogenetic frustrations are actually not too far from the mark, though. I think it is possible to get excited about a new method without looking at it as a be-all and end-all breakthrough. . .as long as you look at the research and stay away from the media version.

Another thing that gets oversold is brain imaging. Again, cool, but not as magical as it’s portrayed sometimes. Lots of times. Virginia Hughes talks realistically about the limits and potential of neuroimaging.

A longread (28 pages) on critical thinking. I have to admit, it’s still open in another tab as I write this. Written from a legal viewpoint, as in how something would stand up in court when exposed to scrutiny, but relevant in a general sense as well.

I often take issue with people who are strict “nurturists” because they are so unspecific about what “environment” is and what it does. Genetics and epigenetics are mechanisms that are, while still being incompletely understood, more logical and straightforward than the more nebulous claims of environmental influence. Many of the people I’ve run across take a Lamarckian viewpoint, or even imagine evolution as a personal change (more akin to Pokemon evolution than anything we see in biology!) So I read Developmental Plasticity and the “Hard-Wired” Problem all the way through, and was pleasantly surprised to see a thoughtful and detailed approach to the “Nature vs. Nurture” question. I don’t know how convinced I am, but it’s more than I’ve been by anyone else presenting this argument.

Genetics/Epigenetics

If you wish to make a gene from scratch explains that, well, it’s not really as easy as that.

Cath Ennis explains how epigenetics works in two parts.

Somehow not as freaky when they’re kittens, and funny to see domestic cat behavior in response to the intrusion of the camera.

I’m going to try to start up with this again, because I’ve lost track of some of the neat things I’ve found. This is going to be a slightly different format, just because the easier I make it, the more likely it is that I’ll be able to keep up with it. It’s also short, because I threw it together in just a couple of days.

Brain stuff:

NIH scientists take totally tubular journey through brain cells I haven’t gotten far enough in DD#2’s Neuroscience textbook to read about microtubules, but now I think I have to. Cool stuff.

DARPA is a US government run defense program that is working on a lot of cool technology, and some of that is on the brain. There’s a lot of potential for electronic stimulation to treat mental illness in a way that is more targeted than medications. New venture aims to heal disrupted brain circuitry to treat mental illnesses looks at some of what they hope to be able to do.

MIT is doing some fascinating research at the molecular level into mental illness. Shining Light on Madness is a somewhat long article, but well worth reading to the end if you want to know what’s being tested, why, and how it’s going to be examined. h/t to Antonei B. Csoka for linking it on Twitter.

In the meantime, The Brain Initiative is finding fascinating information about how the brain works.

Pseudoscience

Lynn Stuart Parramore has an excellent article, Excuse me, is that snake oil gluten free? that explores some of the magical thinking behind the free pass we give Big Placebo, and why we need a little more skepticism.

Deepak Chopra has issued a “challenge” to, essentially, disprove every single claim he’s ever made in a single paper. Steve Novella explains it brilliantly. Easily movable goalposts included.
