More about bottled water: it may sex you up

Via Wired, it seems that bottled water has some contaminant issues (like that whole scare about polycarbonate water bottles). I still think that leachates are not so great a concern as people think, but most things that will get people to stop drinking bottled water are good ideas in my book.

The study referenced used snails to measure the effects of sex hormone analogues (probably pthalates) that are used as plasticizers in all kinds of things these days. Snails grown in bottled water tended to have a lot more little snails. That is an indicator that there might be some hormone analogues coming out of the plastic.

I doubt the effects on humans will be so easily determined.

Medical Hypotheses about belly button lint

There’s an article in C&EN that led me to about this article in Medical Hypotheses about belly button lint. A real scientist, Prof. Steinhauser of Vienna University of Technology made a careful study of the stuff. I almost wrote serious scientist, but I think Prof. Steinhauser would agree that he is a funny scientist.

The upshot is that his hypothesis seems to be true: if you have belly hair, you are probably more prone to belly button lint.

The reactions to this 2+ year trial have been mixed. I certainly think he deserves an IgNobel award. That is mixed praise at best. But I will say this: there is a place for frivolous science. Frivolous is not the same as wasteful. A study that is funny, interesting and still rigorous and well designed constitutes a feat.

I would make the analogy of a serious columnist writing a humor piece. It’s still journalism and it’s still an opportunity for good writing. In a similar way, science with a spirit of levity still deserves to be called science.

Darth Vader's Work Ethic

It struck me this evening that we don’t really know much about Darth Vader’s work ethic. Does he work late? Weekends? It’s totally unclear. What are the hours like for a sith apprentice? For that matter, what about the Emperor, Himself?

It has a lot to do with a TED talk on glamour. By the old definition of the word, the Dark Side has a lot of glamour. It has a seductive, deceptive allure. But glamour has nothing to do with hard work. In fact, if it turned out that Darth Vader spent a lot of his time studying prospective spacecraft designs, thumbing through blueprints and tapping his chin, it clashes with his whole image. I find it strange to think that a character who represents ruthless effectiveness is not superimposable on the prerequisite behavior for effectiveness.

In fact, Vader fails at almost everything in the films. He has no self control. He loses the Death Star and his command ship. I think the films could have emphasized Anakin’s laziness more. I think that’s what got Vader into trouble. Always trying to take the easy way out and get everything at once. That’s what gets him in trouble again and again.

There’s a lesson there.

"Miracle" water for cleaning is probably not all that miraculous

Alert Reader Jason strikes again! About a week ago, the L.A. Times covered the following story.

Simple elixir called a ‘miracle liquid’

It turns out to be less miraculous than it might seem. What you have here is the electrochemical generation of dilute bleach and dilute hydrochloric acid. This is a process that has been done industrially for a century, and now you can do it at home. Or you could just buy a bottle of bleach and a bottle of vinegar.

Firefox shortcuts

I’ve found a few shortcuts in Firefox that I love.

Ctrl-tab : switches among open tabs
Ctrl-w : closes the current tab
Ctrl-shift-t : re-opens the last tab you just closed

I also found a shortcut that I hate:

Ctrl-q : quits the whole program instantly
Ctrl-shift-w : closes the current window

I keep reaching for ctrl-w and hitting ctrl-q by mistake

This little plug-in, keyconfig, lets you fix that:
