Prophylactic vs. Poison

Chalk one up for the forces of anti-science, quackery, and pseudoscience. The citizens of Portland, Oregon just handed them a huge victory the other day when they once again rejected water fluoridation in a referendum: Fluoride supporters, it appeared, had everything going for them. Five Portland city commissioners had voted to add fluoride to the…

A new book from Gerald Markowitz and David Rosner tells the disheartening story of our country’s ongoing failure to fully protect children from lead poisoning

“Fluoridation is the single most important commitment a community can make to the oral health of its children and to future generations.” -C. Everett Koop Most weekends, I take on a lighter topic, as a way of taking a break from the deep physics, astronomy, and science we share during the week. But every once…

The will of the voters in Portland, Oregon has endured for more than fifty years, for the fourth time rejecting fluoridation of the city's tap water in a ballot referendum. On Respectful Insolence, Orac writes "public water supplies are a precious commodity. To justify putting something in them requires good evidence of safety and efficacy." And continues "since 1945 the fluoridation of drinking water has reduced tooth decay by 40-70% in children and tooth loss in adults by 40-60%." Orac respects Portlanders' right to more cavities, but says "classic antiscience arguments" won the day at the polls. There were posters and comics likening fluoride to a deadly poison—which, in drastically different concentrations, it is. Orac says "the dose makes the poison, and the levels used in municipal water supplies has a long history of safety." Elizabeth Grossman chronicles a different poison on The Pump Handle: lead, which according to the CDC, will harm you at any exposure. Unlike fluoride, lead plays no known role in human health, and can cause severe neurological damage. But it does have useful properties when mixed with paint. The US banned lead paint in 1977, but it still exists in some 30 million homes across the country, and is still used worldwide.

Molluscs have amazing super-powers. But you know what? So do humans. We air-breathing terrestrial bipeds are able to enter strange alien worlds and return with a digital record of the events that even the lubbers among us can appreciate.

You can’t! There’s a fungus among us—a hundred different species in fact—and nearly all take up residence on our feet, according to a study that appears in the journal Nature this week. Only a few fungi species were found on other body parts known to house fungi—such as behind the ears and on palms—according to…

This is the question everyone eventually asks themselves. The answer is no. They live all over your body in the follicles of your hair. But, the situation is much more complicated than that, and in fact there is a lot we don’t know about these mites. But, there is a scientist who may be willing…

Physical Science

Number theory is chock-full of easily stated problems that are very difficult to solve. One such is the twin primes conjecture, which asserts simply that there are infinitely many twin primes. I’ll assume you know what a prime number is. Twin primes are primes that differ by exactly two, such as 3 and 5, 5…

“Because dark energy makes up about 70 percent of the content of the universe, it dominates over the matter content. That means dark energy will govern expansion and, ultimately, determine the fate of the universe.” -Eric Linder It’s been a while since we’ve spoken about dark energy, and we were just talking about Einstein’s greatest…

Last week, I spent a bunch of time using VPython to simulate a simple pendulum, which was a fun way to fritter away several hours (yes, I’m a great big nerd), and led to some fun physics. I had a little more time to kill, so I did one of the things I mentioned as…

The federal, State and local authorities investigating the West Fertilizer plant disaster each have different responsibilities and expertise. The ATF is acting like its task is the only one that matters.

There are good reasons to believe that global warming leads to more storminess, but the exact nature of that transition is unclear and hard to measure. Part of the reason for this difficulty is that a given type of storm may become more likely under certain conditions caused by climate change, while a different kind…

I think the accusation that I’ve “stalked” fellow blogger Abbie Smith have been made one too many times. But I’m not sure. Is this the point where I lay out the exact sequence of events of what happened between us? What do you think?

Pope Francis said some interesting things at mass yesterday.

I was discussing SciArt on several occasions with different people recently and was fishing for a way to classify different SciArt in order to make a particular point – the point being that the type of SciArt I find most interesting and valuable is in the minority. Basically, it seems there are 3 (or maybe…

Actions have consequences. No matter how much the person might want to try to hide from the consequences of one’s actions, they frequently have a way of coming back, grabbing you by the neck, and letting you know they’re there.

Just when I thought I was out, they pull me back in. OK, I know I use that line entirely too much, but I also don’t really care. When something fits, wear it. And if it doesn’t fit, you must acquit. Sorry, I’ll stop. I’m in a weird mood as I write this. But it’s…

Brain & Behavior

I was just digitally flipping through a new book called “Crime Against Nature“, which describes various reproductive behaviors in the animal kingdom. It is written by an artist, Gwenn Seemel, not a scientist, so I cannot vouch for the scientific accuracy of the book as a whole. However, the illustrations are quite nice and the content is seemingly scandalous,…

Dr. Kerstin Lindblad-Toh at Uppsala University (Sweden) who specializes in comparative genomics and Dr. Åke Hedhammar, SLU (Sweden) recently identified a novel gene in German shepherd dogs, PKP-2, that encodes a protein (plakophilin-2) important for regulating proper skin structure and function. This protein was found to be associated with canine atopic dermatitis (i.e. doggy eczema), a…

I have to admit — I’ve always been more of Star Trek fan rather than Star Wars.

Jobs

Earlier this month, Florida lawmakers wrapped up their latest legislative session. And nearly 500 miles south of Tallahassee in Miami-Dade County, workers’ rights advocates breathed yet another sigh of relief.

Eric Rodriguez and his colleagues at the Latino Union of Chicago quite literally meet workers where they’re at — on the city’s street corners. Many of the day laborers who gather there are hired to work construction at residential housing sites. Work arrangements are hardly formal and day laborers are frequently subjected to unnecessary and illegal dangers on the job. Unfortunately, worker safety is often kicked to the curb in the street corner marketplace.
