I thought I'd share some of the nifty random photos I'd taken last month:

I was fine on Saturday. Better than fine actually. I was feeling great after a much needed rest. We both were. And then we woke up Sunday and felt like crap. Sneezing, coughing, stuffy heads and headaches.

What the heck? I checked our HEPA air filter. The carbon pre-filter was a bit dirty, but otherwise it was fine. The air quality had to have changed drastically. Sure enough, when I walked outside I could see a haze in the air. I've had trouble breathing for the past three days, and constant coughing.

It's very frustrating to see, since the Hill Country area where we live is usually fairly clean air. This kind of haze is a daily rush-hour phenomenon in Houston, but not out here, It usually means that there's a fire burning somewhere, or pollutants blowing in from elsewhere.

I did some checking and it turns out I was right - on both counts. Some of the bad air is due to drift from fires out west and some is due to pollutants originating in industrial areas of the mid-west. To add insult to injury, we're also sitting under a cloud of dust blown in from sub-Saharan Africa. That's right, a dust cloud from 6,000 miles away is sitting on top of parts of Texas and Mexico. Add that to high ozone levels due to the heat and you've got a recipe for respiratory problems.

Via National Geographic: Heart Drug May Block Stress of Traumatic Memories

Researchers say the beta-blocker propranolol, commonly prescribed to treat high blood pressure and heart problems, disrupts the way the brain stores memories.

If taken at the right time, the drug may benefit people who suffer post-traumatic stress disorder (PTSD), said Joseph LeDoux, a neuroscientist at New York University.

"We're not erasing memories," he said. "But we think it will reduce the emotional component of the memory."

The science journal Nature reported Wednesday that LeDoux and colleagues are conducting a clinical trial of propranolol in PTSD patients.

And check out this site: Wisconsin's Great Lakes Shipwrecks. Here's a blurb about it from the Humbul Humanities Hub:

This website presents all the shipwrecks on the American Great Lakes that have been studied by the University of Wisconsin. The oldest shipwreck is the Niagara, a steamer launched in 1846 and wrecked ten years later. Most of the other shipwrecks date to the second half of the nineteenth century and early twentieth century. [...] Overall the website is very useful as general introduction to underwater archaeology and many of its techniques. The documented shipwrecks provide much information on the maritime history of North America in the years of the shipwrecks. Since all the shipwrecks date to a period about one century long and have been found in a relatively small space, they also provide much information on that region of America between the nineteenth and twentieth centuries.
