The Swedish Media Council released a report reviewing the state of the research in Swedish, I've summarized and translated below. There is also an article published in English over on the local. From the summarized version of the report: The Swedish Media Council has gone through research databases and gathered studies on violent videogames effects on ...

Yes, some non-ionizing radiation can cause health problems. Your question is very broad - you've asked about non-ionizing radiation generally, rather than say specifically about radio waves. And that makes it much easier to answer in the affirmative. See, for example, photochemical damage of the retina from high-intensity visible light: Also, high-...

What: The reason there are unusual instructions like : not entering your car not using a CB radio not using a mobile (cell) phone ... while refueling is because of static discharge - you feel it when a car zaps you.

The evidence with respect to seat belts suggests that the law had no effect on total fatalities but was associated with a redistribution of danger from car occupants to pedestrians and cyclists. Which evidence? "In Britain, as in Australia, and as in the eight European countries examined by Isles, in the year that the wearing of seat belts became ...

Overall fatalities have been steadily decreasing: Source: Image from Wikipedia based on data from US NTSB This clearly contradicts "risk compensation" theory, with which you'd expect a flat line. Now, as for the quoted article, there quite a few problems: causality: article suggests that in case of Denmark introduction of belt laws caused increase in ...

First of all, gasoline is used because it is very good at being ignited by a spark, and it contains a lot of chemical energy. So on the face of it, a spark could ignite gasoline vapours in the air, and a vehicle with sufficient static charge could produce a spark if suddenly grounded. It is possible, and extremely rare. Two things need to happen before ...

The modern, public information is that tobacco smoke contains many chemicals which cause cancer: American Lung Association There are approximately 600 ingredients in cigarettes. When burned, they create more than 7,000 chemicals. At least 69 of these chemicals are known to cause cancer, and many are poisonous. Cancer Research UK Some cancer-causing ...

Since it was suggested to use (MZ) twin studies to prove causation... that won't completely work if done observationally, e.g.: While MZ co-twin control studies can provide more accurate estimates of the returns to education than analyses of single individuals, these studies do not entirely obviate the need to control for differences between university ...

Red seems to have some effect on performance in well constructed experiments and in sport, though we could do with further studies The trouble with many studies on the relationship between colour and performance is that they are based on speculative theories and rely on poorly controlled experiments. This is summed up by the authors of this paper in the ...

Johnson, Jones, Scholes, and Carras (2013) published a review of research literature that mostly focused on the positive aspects of video gaming, which they argue have been overlooked due to dominant societal preoccupations with theories about its effects on violent behavior (Kutner & Olson, 2008; Ferguson, 2007; Ferguson et al., 2013). They include a ...

Summary Studies with mice and rats have shown there may be an increase in some rare forms of cancer (in schwannoma and glial cells) but if so, the effect is very small and the mechanisms remains unclear. This does not show a link with cancer in humans (certainly, the effect cannot be large, or it would show up epidemiologically), but it does raise the ...
