In this episode of Life, the Universe & Everything Else, Gem Newman discusses atheist activism and the skeptical community’s problems with equality with Greta Christina. Also on this episode, a new instalment of Where’s My Jetpack? This week Old Man Newman asks, “Where’s my lab-grown meat?”
In the second part of Life, the Universe & Everything Else‘s two-part series examining organic farming and genetically engineered foods, Mark Forkheim, Leslie Saunders, Gem Newman, and Laura Creek Newman discuss the science of genetic engineering and some of the very real problems with Monsanto.

Here, Mark Lynas (who has rapidly become my favourite environmentalist) takes aim at a junk science paper out of Australia claiming that a diet consisting of only “genetically modified” grain vastly increases the risk of severe stomach inflammation in pigs. Really, it shows nothing of the kind.
15% of non-GM fed pigs had heart abnormalities, while only 6% of GM-fed pigs did so. Similarly, twice as many non-GM pigs as GM ones had liver problems. Why no headlines here? “Pigs fed non-GMO feed 100% more likely to develop heart and liver problems, study finds” – I can just see it in the Daily Mail. But of course negative results were not what Carman et al were looking for.
Table 3 actually shows that many more pigs fed non-GMO feed had stomach inflammations than those with GMO feed. So 31 non-GM pigs had “mild” inflammation, while only 23 GM pigs had it. For “moderate” inflammation, a GMO diet again seemed to be beneficial: 29 non-GM pigs had moderate inflammation of the stomach, while 18 had it. So that’s 40% vs 25%. Do Carman et al perform a test for statistical significance to see if GMO feed has a protective effect on pigs stomachs? Of course not – that’s not the result they are after. These findings are ignored.
Instead, it is the next line of data that they play up: for “severe” inflammation 9 non-GM pigs were determined to have it, while 23 GM-fed pigs had it. Shock, horror. You can immediately see how the data is all over the place from the previous results, which also rule out any causal mechanism with GMO feed – if GMO feed is causing the severe inflammation, why is the non-GMO feed causing far more mild to moderate inflammation? It’s clearly just chance, and all the pigs are not doing well and suffering stomach problems: about 60% of both sets had stomach erosion.
Correction: Greg mentioned that the Year Without a Summer (1816) was precipitated by the eruption of Krakatoa; this “volcanic winter” is actually attributed to a succession of volcanic events culminating in the eruption of Mount Tambora, which began in 1815.
Bad Science Watch is an independent non-profit activist organization dedicated to improving the lives of Canadians by countering bad science. The group is driven by a vision of a safer, healthier, and more prosperous Canada where critical thinking and sound science are paramount in the making of important societal decisions.
December saw the completion a project investigating anti-WiFi activism in Canada. The project committee (which I chaired) presented its findings to BSW, and the full report is now available on Bad Science Watch’s project page.
I’ll quote here from the conclusion of the paper:
We have been unable to identify any high quality reproducible evidence that any symptom of idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF) is caused by exposure to nonionizing electromagnetic radiation. Systematic reviews of both provocation studies and purported treatments for IEI-EMF support the conclusion that EMF is not the cause of the syndrome.
Despite the claims made by the authors of one review paper and the aforementioned anti-WiFi groups, Bad Science Watch was unable to locate any compelling evidence of legitimate scientific debate about WiFi induced illness, or the safety of low-level EMF exposure in general. While fringe groups continue to present flawed arguments and promote poorly designed experiments, the preponderance of research on the matter robustly dispels the connection between WiFi and IEI-EMF. For those tasked with making decisions about the inclusion of WiFi technology in their organization, school, or home, we can find no reason to ignore the advice of health organizations worldwide. The benefits of WiFi are numerous and varied, and there is no compelling evidence that any health effects arise as a result of this technology.
