LATEST UPDATE HERE … new numbers just in from WHO, and they are bad. I had suspected this might be the case. Disease like Ebola are potentially easily cured using serum. Here’s the idea. Someone gets the disease and survives, and their body now produces products that give them an immunity. So, you take a…

So, you accept the science of climate change and global warming as legit. But you often encounter people, at family gatherings, on your Facebook page, on Twitter, at social events, etc. who don’t. Do you keep your mouth shut when someone says something clearly wrong that brings the science into question illegitimately? If you do,…

LATEST UPDATE HERE It is true that this particular outbreak of Ebola has taken health officials somewhat by surprise. It is impossible to know, but I suspect that if you had asked a few ebola experts, a year ago, if there could be an epidemic that would spread across three or four countries, infect a…

The US Drought Monitor produces an assessment of drought conditions every week. The drought in California has taken a large jump over the last few days, with the highest category, “Exceptional,” jumping from 36.49% to 58.41%. At the start of the calendar year, that category was represented in California by 0%, so this is a…

Mark Your Cosmic Calendar: 774/775 One wonders if anyone felt it. Did Charlemagne feel it as he led his forces across Pagan Saxon Westphalia, knocking down Irminsuls and making everyone pretend to be Christian or else?

LATEST UPDATE HERE UPDATE: The latest numbers do not indicate a weakening of the outbreak. (See list of new cases below. Several graphs have been updated as well) UPDATE: More detailed discussion of transmission of Ebola UPDATE: I note with sadness the death of my neighbor (though I did not know him) of Patrick Sawyer,…

The 2000 election was probably won by Al Gore. But George Bush was put into office anyway. Imagine what this world would be like had Gore been ensconced in the white house? The Tea Party would probably have emerged sooner and madder, but less organized; global climate change would have become a widely accepted issue…

Feral Cats as Invasive Species

The ranger stood on the dirt road, facing south, and the rest of us, scattered about the parked safari truck, facing north and paying close attention to what she was saying. The sun was slipping quickly below the red sand dunes to our west, and the day’s warm breeze was rapidly changing to a chill…

There are a lot of great and admirable religious leaders. Gandhi. Some other guys. But there are also a lot of bad ones. Did you ever want to have a place to look up who these dudes are (and most, but not all, are dudes)? This may be especially helpful if you find yourself in…
