glyphosate roundup convulsions

Glyphosate (Roundup) causes convulsions in nematodes! What?

And here we go again, another paper that attempts to link something terrible, in this case, convulsions, to the weedkiller glyphosate, also known as Roundup. Except this is about nematodes or roundworms.

I seem to be writing about roundworms a lot lately, I wonder why. Oh wait, I remember. Quacks were pushing a drug, that treats roundworm infections, to be used against COVID-19. Of course, you all remember ivermectin.

Let’s look at glyphosate and this new paper, which made me laugh. Then I got annoyed.

glyphosate causes autism

Glyphosate causes autism – another debunked vaccine myth

Another one of those pseudoscientific tropes from the anti-vaccine religion has reared its ugly Bigfoot head – glyphosate causes autism. And, of course, the anti-vaxxers believe that vaccines are filled with that nasty chemical, so by some weird transitive logic, they think that vaccines cause autism because of glyphosate.

Yeah, no.

Of course, the belief that “vaccines cause autism” has been thoroughly debunked by powerful, robust, repeated clinical and epidemiological studies. It is “settled science” (and read the link, so that you actually understand what is meant). Now we have the oft-repeated myth that glyphosate causes autism spectrum disorder (ASD). The evidence that supports that claim is fairly weak, possibly nonexistent.

Even if it did, and most scientists are highly skeptical of the claim, we still know that there is almost no glyphosate in vaccines. And once again, even if there were and even if glyphosate causes autism, we know that there is no link between vaccines and autism. None. 

A few years ago, Emily Willingham, Ph.D., whom I consider to be one of the leading ASD scientific experts on this planet, wrote a hysterical and scientifically skeptical article about all of the popular causes of ASD – Dr. Willingham noticed that there were new claims about what causes autism. Parents need to blame someone for their child’s neurodevelopment, so that’s how vaccines got into the crosshairs.

But let’s look at some of the science, and figure out if there’s any mechanism by which glyphosate causes autism.Read More »Glyphosate causes autism – another debunked vaccine myth


Glyphosate linked to non-Hodgkin lymphoma? Analysis of new study

A new study has been published that claims that the herbicide glyphosate is linked to an increased risk of non-Hodgkin lymphoma,  a cancer of the lymph tissue. Of course, once a study like this hits the interwebs, everyone becomes panicked that glyphosate causes cancer.

I want to take a look at this paper because I am generally distrustful of any claims that “XYZ causes cancer!!!!!!!!!!!!” 

Cancer myths are pervasive, and a lot of fear of cancer is based on those myths. So let’s take a critical eye and examine the peer-reviewed paper that claims that there is a link between glyphosate and non-Hodgkin lymphoma. There is a lot there, but there is also a lot of overreaction. Read More »Glyphosate linked to non-Hodgkin lymphoma? Analysis of new study

GMO corn

GMO corn – safe and more productive according to new meta-review

As I wrote recently, the science is settled on “controversial” topics like vaccines and anthropogenic climate change. The science is also settled on genetically modified organisms (GMO) – real science, not anecdotes, beliefs, misinformation, and lies, tells us that genetically modified agricultural products are safe for the environment, for animals, and for humans. Now, we have a new, powerful study that shows us that GMO corn is not only safe but also increases production of corn.

GMOs are one of those modern technologies that many people avoid, mainly for irrational and unscientific reasons. Of course, many people push fear, uncertainty, and doubt (FUD) about GMOs using little or no scientific evidence to support their claims.

But I’m here to provide real, published, peer-reviewed scientific evidence that contradicts that fear about GMOs – well, at least about GMO corn.Read More »GMO corn – safe and more productive according to new meta-review

courts and science

Courts and science – talc and glyphosate probably do not cause cancer

I’ve written about this many times before – courts do not get to decide what is good or bad science. Although courts and science may not necessarily be incompatible, attorneys, juries, and judges are generally not trained in scientific research, scientific methods, scientific publications, and/or scientific reasoning.

Two relatively recent cases are strong evidence that courts and science can be quite incompatible. In the first case, a jury ordered pharmaceutical giant Johnson and Johnson (JNJ) to pay US$4.69 billion in damages to 22 women who claimed that the company’s talcum powder products caused ovarian cancer. In the second case, a jury ordered chemical manufacturer Monsanto to pay US$289 million to a janitor who claimed that Round-Up (glyphosate) caused his terminal cancer.

The problem with both of these cases is that there is, at best, some weak, unrepeated scientific evidence that supports their claims. However, if you refrain from cherry-picking articles on PubMed, you’ll find that the vast majority of research either doesn’t support their claims or even shows that there are no links between talc or glyphosate and cancer.

Let’s take a look at the science in both of these cases, and then, let’s find out why courts and science are not necessarily compatible. And remember, this isn’t a recent problem – an American court once rejected evolution during the infamous Scopes Monkey Trial. So science has been skeptical of the involvement of courts and science for a very long time.Read More »Courts and science – talc and glyphosate probably do not cause cancer

Glyphosate causes cancer

Glyphosate causes cancer? – large scientific study says no

One of the tropes of the pseudoscience world is that glyphosate causes cancer – but what does real science say? Well, numerous large epidemiological studies have yet to provide evidence of a link that would convince us that the herbicide has any link to any cancer.

Recently, another article in a prestigious cancer journal looked at thousands of  individuals exposed to glyphosate, and once again, have found no convincing evidence that glyphosate causes cancer. The totality of evidence, unless you are into glyphosate- and GMO-free cherry picking, continues to lead us to a simple conclusion – there is no link between the chemical and any of the 200 or more types of cancer.

One of the major issues with the tropes and myths about glyphosate is that many anti-science liberals tend to conflate glyphosate with genetically modified crops. This leads to a lot of unsupported hatred of GMO plants, despite the overwhelming scientific consensus that says that GMO agriculture is safe for humans, animals, and the environment – a consensus as broad and powerful as the one that states that climate change is caused by humans.

So let’s look at this new article, and how it fits into the narrative about glyphosate and cancer.

Monsanto glyphosate

Monsanto glyphosate causes cancer – so do apples

Monsanto glyphosate (Roundup)  is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses that are known to compete with commercial crops grown around the world. It has several advantages over many herbicides in that it breaks down in the soil into non-toxic organic molecules, reducing or eliminating contamination of groundwater and lower soils.

Monsanto has developed genetically modified (GMO) grains that are resistant to glyphosate, so that agriculture can apply the herbicide to kill the competitive weeds while not harming the crop. This allows farmers to suppress the weeds while allowing better production out of the grain crop.

Whatever the benefits of Monsanto glyphosate, GMOs and the herbicide are tied together in many minds. And there has been an ongoing effort by many people to claim that glyphosate causes cancer. But let’s look at the science, because maybe we’ll get some information.
