Unnecessary vitamins

America is prone to all manner of food fads. New diets come and go with eye-popping rapidity and this or that food becomes the new magic food that everyone latches on to, before it is replaced by something else. Kale is now the latest miracle food to be dethroned. The problem is that people go overboard with the big new fad and overdo it, rather than taking everything in moderation

Africa becomes polio free?

Maryn McKenna shares the excellent news that midnight August 11 marked one full year with no cases of polio reported in the whole of Africa. It takes three consecutive years of absence for a region to be designated as polio-free but this step is significant nonetheless, given the opposition by Muslim imams in a few countries that nullified the World Health Organization’s goals of making the entire globe polio-free by the year 2000,

Using balloons to provide internet access everywhere

As regular readers know, I am originally from Sri Lanka and so my attention was caught by this report on NPR about a novel way of dealing with the problem of providing internet access to people in remote and hard to reach areas. The island is roughly the size of West Virginia and also mountainous and its long-running civil war that ended only in 2009 left about a third of the country devastated and with limited infrastructure. Although the main cities are highly developed, currently only about 16% of the population is connected to the internet.

The history and futility of car alarms

For pretty much all of us, our first reaction when he hear a car alarm go off is to think “Oh, hell, I hope someone shuts it off soon”. Almost no one thinks about calling the police to tell them that a car is being stolen. I had thought that these were a new invention, within the last two decades or so, but Zachary Crockett writes that they were first developed as far back as 1913.

The continuing struggle over vaccinations

The efforts to fight polio vaccination in some Muslim-majority countries has been a scandal, fueled by a mixture of wrong-headed beliefs by some Muslim clerics about the effect of vaccines and by fears that it is part of some kind of plot by the CIA and other western spy agencies. The latter charge gained credibility because of the shameful use by the US of a fake vaccination scheme to try and find Osama bin Laden but even then there is absolutely no excuse for harassing or murdering workers administering vaccines or preventing children from receiving one of the greatest medical breakthroughs that has eradicated a deadly disease from almost the entire world.

Smoking and Morton Downey, Jr.

Before Glenn Beck and Rush Limbaugh, the conservative media outrage machine was led by abrasive talk show host Morton Downey, Jr., whose programs were a combination of Limbaugh politics and Jerry Springer format, where he would have on political guests who would be goaded to attack each other and create shouting matches, with Downey attacking the liberals and liberal views in the harshest terms. The studio audience would be raucous and conservative audiences loved it.

Review: Merchants of Doubt

This review will deal with both the book and the documentary based on it. The book was written by two historians of science Naomi Oreskes of Harvard University and Erik M. Conway and was published in 2010, while the documentary was directed by Robert Kenner and released in 2014 and has just been released on DVD. I can strongly recommend both. The book is very clearly written and makes a compelling case for the authors’ thesis. Although the documentary is based on the book, its emphasis is different (dealing mostly with the climate change debate) and provides new information that is not in the book. Here’s the trailer.

When your car gets hijacked by remote hackers

Cars are now sophisticated computers on wheels. The technological improvements have enabled them to approach the point that they may be able to drive themselves. But that means that, like any computer, they are also now vulnerable to hacks by people who can break into those computer systems and take control of the car out of the driver’s hands and operate it remotely.
