Everyone has heard by now that there is a catastrophic oil leak in the Gulf of Mexico. I’m not an oil expert, so I won’t discuss this much here. There is a lot of information already in the media. I am quite familiar with drinking water issues, however, and over the weekend we received news…

John Snow

Yesterday I gave a nod to an important epidemiologist, the late Alice Stewart. I’m old enough to have known her, but not old enough to know the most famous epidemiologist of all — indeed sometimes called the “Father of Epidemiology” — Dr. John Snow. Snow is also claimed as the “Father of Anesthesiology” because he…

Still working on the grant and today was our Mock Study Section. It was an experiment that in the view of all participants (there were about 35 reviewers in the room) was a highly successful one. But after hearing the litany of strengths and weaknesses I’m worn out. I naturally focussed on the weaknesses. We…

I don’t fly as much as I used to but I still fly too often for my likes and when the cart comes around for the free beverages it’s either orange juice “with no ice” or a bloody mary mix “with no ice.” I rarely drink water, but if I did, I would never drink…

Viruses and sandcastles at the beach

It’s Saturday and it’s summertime and Mrs. R. and I are still in the city. OK with me. I’m a city boy and find it easiest to maintain upright posture on asphalt, but my bride of 37 years likes the beach, so most summers we go off for a few weeks to the seashore (speaking…

Orgies and antibiotic resistance

When a small body of water, say a slow flowing creek or water in a drainage ditch, “goes septic” it starts to stink, often giving off a rotten egg odor (hydrogen sulfide, H2S). This isn’t a sign that the water is polluted in the chemical sense of toxic materials. It means that so much organic…

Pharma fish found

There has been more talk recently that our wastewater are loaded with pharmaceuticals. No surprise. People often dump out of date pills down the toilet, but much more important, they send them flushing in by excreting them. That’s wastewater, though, not drinking water. They do get into drinking water, too, but at much lower levels.…

Secrets of the toilet

Way back on New Year’s Eve of 2005, when we were still hosted over at Blogger, I did one of my more popular posts about how a toilet works. Most people don’t know. I’m guessing they have some kind of vague mental image that when you push the toilet handle a trapdoor opens up somewhere…

A pill with a glass of water, hold the pill

One of the triumphs of 19th and 20th century public health was the provision of piped water into cities and towns. With the use of modern methods of disinfection (primarily chlorination) water as a source of mass distributed poisons rapidly receded, and with it the preponderance of infectious diseases that were the scourge of urban…

Whether they are called the White House Press Secretary or the regime’s Information Minister, they seem to have in common one characteristic: they are professional liars. It goes without saying that all of Bush’s press secretaries have been blatant liars, but it’s also true of Clinton’s and virtually very one of their predecessors. Some of…
