Former Bush Homeland Security Secretary Tom Ridge just wrote a book in which he tells us what we already knew, according to Think Progress:
[He]was pushed to raise the security alert on the eve of President Bush’s re-election, something he saw as politically motivated and worth resigning over.My initial reaction: If true, those responsible should be criminally prosecuted. My second reaction: They won't be.
The Onion is now weighing in on health care reform. The title to the Onion's article says it all: "Congress Deadlocked Over How To Not Provide Health Care." It's well worth a read, if you like humor with an especially sharp edge on especially serious topics.
Quick! Name a small and numerous component in the brain that allows us to think. If you said "neuron," you would be only partially correct. According to Carl Zimmer's blog at Discover, "The Loom," evidence is accumulating that thinking is also accomplished by astrocytes
—named for their starlike rays, which reach out in all directions—are the most abundant of all glial cells and therefore the most abundant of all the cells in the brain. They are also the most mysterious. A single astrocyte can wrap its rays around more than a million synapses. Astrocytes also fuse to each other, building channels through which molecules can shuttle from cell to cell.To put glia into a broader perspective, consider Zimmer's introduction to his post on glia:
I’ve asked around for a good estimate of how many neurons are in the human brain. Ten billion–100 billion–something like that, is the typical answer I get. But there are actually a trillion other cells in the brain. They’re known as glia, which is Latin for glue–which gives you an idea of how little scientists have thought of them.
It has now been shown that astrocytes can sense incoming signals, respond with calcium waves, and produce outputsIn other words, they have at least some of the requirements for processing information the way neurons do. Alfonso Araque, a neuroscientist at the Cajal Institute in Spain . . . find that two different stimulus signals can produce two different patterns of calcium waves (that is, two different responses) in an astrocyte. When they gave astrocytes both signals at once, the waves they produced in the cells was not just the sum of the two patterns. Instead, the astrocytes produced an entirely new pattern in response. That’s what neurons—and computers, for that matter—do. If astrocytes really do process information, that would be a major addition to the brain’s computing power . . . neuroscientist Andrew Koob suggests that conversations among astrocytes may be responsible for “our creative and imaginative existence as human beings.”
Early this week, Representatives Ed Markey and Anna Eshoo introduced the Internet Freedom Preservation Act of 2009. It's common sense and it's fair, but just watch as the telecoms now do everything they can to destroy it. Why do we need this Act? Here are a few recent examples:
The issue of unrestricted Internet access has gained new traction on Capitol Hill in the wake of reports that Apple and AT&T are each blocking or preventing users from accessing services for the mega-popular iPhone, which is exclusive to AT&T at the moment. FCC chairman Julius Genachowski recently sent letters to Apple, AT&T, and Google asking why Google Voice, the company's popular free calling service, was rejected for use on the iPhone.
Representatives Markey and Eshoo made this statement about the need for this net neutrality bill:The Internet is a success today because it was open to everyone with an idea,” said Rep. Markey. “That openness and freedom has been at risk since the Supreme Court decision in Brand X. This bill will protect consumers and content providers because it will restore the guarantee that one does not have to ask permission to innovate. The Internet has thrived and revolutionized business and the economy precisely because it started as an open technology,” Rep. Eshoo said. “This bill will ensure that the non-discriminatory framework that allows the Internet to thrive and competition on the Web to flourish is preserved at a time when our economy needs it the most.”
Here's a summary of the bill:H.R. 3458, the Internet Freedom Preservation Act, is designed to assess and promote Internet freedom for consumers and content providers. The bill states that it is the policy of the United States to protect the right of consumers to access lawful content, run lawful applications, and use lawful services of their choice on the Internet while preserving and promoting the open and interconnected nature of broadband networks, enabling consumers to connect to such networks their choice of lawful devices, as long as such devices do not harm the network. The legislation also directs the Federal Communications Commission (FCC) to promulgate several rules relating to enforcement and implementation of the legislation, including rules to ensure that providers of Internet access service fulfill the duties and disclose meaningful information to consumers about a provider’s Internet access service in clear, uniform, and conspicuous manner.
To do your part, click on this tool to determine the phone number of your representative, then call to ask for his or her position on this bill. You are then given a further option to report the result to Free Press/Save the Internet. I made the call and spoke directly with a legislative assistant. She didn't know the answer (re Representative Russ Carnahan), but promised to find out and report back to me. The entire process only took a couple minutes. You can also sign a Petition that will be delivered to Congress by visiting Save the Internet. Again, it only takes a minute. Your grass roots investment of a few minutes can counteract tens of millions of dollars the telecoms will spend on lobbyists, misleading media campaigns and wads of cash that the are putting into the palms of your elected representatives. Be empowered!
I've been having fun taking photos with my Canon SD1100SI, as usual. I carry it almost everywhere. I especially enjoy when an ordinary thing looks extraordinary. While driving yesterday, I noticed a beautiful sunset. I handed my camera to my 11-year old daughter JuJu, who was sitting in the back seat, and asked her whether she would be willing to take a photo of the sunset (see below). The shape of the sun is what intrigues me. Now, really. What's going on? Was the sun starting to take the shape of the Virgin Mary?
I've noticed many other extraordinary ordinary things lately. That was actually my purpose for carrying around a small camera--the camera reminds me to actually look at the many amazing ordinary things surrounding me (and you). Things like this bumble bee at work in my neighbor's yard.
Insects are especially fun and easy to photograph. All you need is a "macro" feature on your digital camera, and most cameras have that feature. I do love the macro feature, because it reveals things you simply can't see in person. 
Looking at insects makes me wonder whether they are complicated robots or simple animals. And what are we, for that matter, given that we are confirmed cousins of these insects? To the right is another recent subject: a spider I noticed on a screen on my back porch. To give you an idea, this critter was merely 1/3 of an inch in width.
Here are a few more things I'd like to share. First of all, a backyard snail, a gastropod. It 
is a close cousin of cephalopods (mollusks).
That's all for now, except for this dragon kite flying high in this exceptionally blue sky over Forest Park in St. Louis, Missouri.
