Pesticides cause autism – the scientific evidence is quite weak

pesticides cause autism

Along with the thoroughly debunked “vaccines cause autism,” a related trope is pesticides cause autism spectrum disorder (ASD). The evidence that supports that claim is fairly weak, possibly nonexistent, but that’s what we do here – examine the evidence.

For reasons beyond the scope of this blog and my interests, parents need to find blame for why their children may have been diagnosed with an autism spectrum disorder.  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. Older mothers. Older fathers. Depressed mothers. Fingers. Facial features. Facial features?

Today, I keep seeing the new claim that pesticides cause autism. Time to see what kind of science supports this claim. Continue reading “Pesticides cause autism – the scientific evidence is quite weak”

Prevent Zika virus with GMO mosquitoes – Frankensquito returns

Prevent Zika virus – female

Over the past few months, the Zika virus, a mosquito borne disease that is passed from the mother to the developing fetus, has become the focus of a lot of attention because of the danger it poses to the fetus. There are no vaccines or treatments for the virus, so the best we can do is stop the carrier, two species of the Aedes mosquito. Probably the best way to prevent Zika virus spread is with genetically modified mosquitoes, the Frankensquito.

Even though mosquitoes are the main way to be stricken with the Zika virus, it is even crazier than that. Men and women who contract the disease can then transmit it sexually to their partners. So even those who are nowhere near the Zika carrying mosquitoes may be at risk of getting the virus.

Recently, there have been numerous cases of Zika virus infection in  south Florida, and, because of the lack of effective preventative vaccines and treatments, public health officials have looked at other methods to prevent Zika virus. The most effective way is to eliminate the carriers of this virus, mosquitoes.

I have written several articles about these GMO mosquitoes, but that had been with regards to preventing Dengue fever, also a dangerous mosquito carried disease. But just like the “outcry” with the Frankensquito and Dengue fever, we’re hearing almost the same nonsense with respect to Zika virus. Let’s look at the scientific facts, with the hope that some will see the importance of prevention.

Science of organic food – are they healthier?

Organic foods have been increasingly popular these days moving from local co-ops and farmer’s markets to large retail chains that specialize in organic foods (such as Whole Foods) to general large retail chains who dedicate portions of their produce sections to organic produce. Even dairy and meat sections of most supermarket chains have sections that contain organic products.

But what is the underlying science of organic food whatever the source? Is it healthier? Is it worth the additional cost? Is there some indication that farm productivity is higher in organic farms?

It’s time for a skeptical look at the cost and benefits of organic foods.

Stopping dengue fever with genetically modified mosquitoes

Four hundred years ago, the world was so afraid of Galileo’s scientific ideas that the Catholic Church put him under house arrest for the rest of his life. And he was just describing heliocentrism, the astronomical model where the earth revolves around the sun. Very important to our understanding of the universe, but it was not a life or death matter. 

You would assume that if a new scientific idea that would help people live longer and healthier, then there would be no fear. However, that assumption is disproven again and again with the antivaccine gang and the Big Pharma ad hominems that we hear frequently.

As I’ve discussed on a number of occasions, genetically modified organisms, whether they be crops or animals or other organisms, seem to cause an irrational and unscientific concern. GMOs are generally safe, and we have lots of scientific evidence to back that up. But still, people get scared.

Trying to save lives with the Frankensquito

However, that assumption is disproven again and again with the antivaccine gang and the Big Pharma ad hominems that we hear frequently.

Over the past couple of years, I’ve written about an innovative an small UK based biotech firm, Oxitec, which has developed genetically modified male mosquitos, sometimes referred to as  Frankensquitos (at term I fully embrace as being both ironic and descriptive) that would mate with wild females. Those females would produce offspring that would not survive to adults, because they require an antibiotic, tetracycline, in their diet, something that isn’t usually available in the the wild. Over time, with multiple releases of males, the population of the Aedes aegypti mosquito, which is the vector for transmitting Dengue fever. would fall to such a level that transmission of the the disease would be significantly reduced, if not completely stopped.

The “Frankensquito”–trying to save lives in the Florida Keys

Update to an article from last year.

Four hundred years ago, the world was so afraid of Galileo’s scientific ideas that the Catholic Church put him under house arrest for the rest of his life. And he was just describing heliocentrism, the astronomical model where the earth revolves around the sun. Very important to our understanding of the universe, but it was not a life or death matter. You would assume that if a new scientific idea that would help people live longer and healthier, then there would be no fear. However, that assumption is disproven again and again with the anti-vaccine gang and the Big Pharma ad hominems that we hear frequently.

The British newspaper, the Guardian, last year reported that a small UK based biotech firm, Oxitec, is running into public resistance to testing a genetically modified mosquito that may stop the spread of the species of mosquito that spreads dengue fever in the Florida Keys. Earlier this year, the Florida Keys Mosquito Control District (yes, there are governmental entities in Florida that are entirely responsible for mosquito control and abatement) encouraged public comment about the program.

One of the largest concerns for the Florida Keys Mosquito Control District (FKMCD) is Dengue fever, a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4) that are transmitted by the bite of an infected Aedes aegypti mosquito, the most important transmitter or vector of dengue viruses in North America.

Organic foods–are they healthier? Are they worth the extra money?

Note: this article has been updated and re-published. Please view and comment there.

Organic foods have been increasingly popular these days moving from local co-ops and farmer’s markets to large retail chains that specialize in organic foods (such as Whole Foods) to general large retail chains who dedicate portions of their produce sections to organic produce. Even dairy and meat sections of most supermarket chains have sections that contain organic products.

So what are organic foods? They are usually crops, meat or other animal products (milk, cheese, honey) which have been produced without the use of synthetic pesticides and fertilizers, as well as genetic modification and certain preservation techniques such as food irradiation. Also the meats and animal products are produced without the use of antibiotics and growth hormones. Organic farming was pioneered in the early part of the 20th century based on the unproven idea that chemical pesticides and fertilizers supposedly had a negative effect on flavors and nutritional values of foods. Over the years, organic farming has grown into a huge business based on the supposed health and flavor benefits, but also on the the potential benefits that organic agriculture may have on the environmental impact of agricultural chemicals. In addition, there is a lot of concern about the persistence of pesticides on our food sources. Continue reading “Organic foods–are they healthier? Are they worth the extra money?”
