Nazanin Saeidi and Choon Kit Wong have found a new way of killing Pseudomonas aeruginosa, an opportunistic species that thrives wherever humans are weak. It commonly infects hospital patients whose immune systems have taken a hit. It targets any tissue it can get a foothold on – lungs, bladders, guts – and it often causes fatal infections. To seek and destroy this threat, Saiedi and Wong have used the common lab bacterium Escherichia coli as a sacrificial pawn.
Their E.coli recruits produce a protein called LasR, which recognises molecules that P.aeruginosa cells use to communicate with one another. When LasR detects to these chemical signals, it switches on two genes. The first one arms the bomb. It produces pyocin, a toxin that kills P.aeruginosa by drilling through its outer wall and causing its innards to leak out. The second gene detonates the bomb. It produces a protein that causes the E.coli to burst apart, killing itself but also releasing a flood of deadly pyocin upon nearby P.aeruginosa.
Gov. Rick Perry on Thursday stuck by his earlier statement that Texas can secede from the United States — a far-reaching, legally questionable prospect that nevertheless drew Perry a fresh favorable mention by Rush Limbaugh, one of the nation’s leading conservative voices.
The idea of secession — which Perry did not endorse — surfaced suddenly Wednesday after Perry appeared at an anti-tax “tea party” at Austin City Hall, where some in his U.S. flag-waving audience shouted, “Secede!”
Gov. Rick Perry said Thursday there’s no reason to dissolve the United States’ ‘great union’ but that he can understand why Washington’s recent actions would make some want to.
According to The Associated Press, Perry suggested in response to a reporter’s question that Texans might at some point get so fed up with Democratic-led actions in Washington that they would want to secede.
“There’s a lot of different scenarios,” Perry said. “We’ve got a great union. There’s absolutely no reason to dissolve it. But if Washington continues to thumb their nose at the American people, you know, who knows what might come out of that? But Texas is a very unique place, and we’re a pretty independent lot to boot.”
On Thursday, Perry called potential secession a “side issue of Texas history. … We are very proud of our Texas history; people discuss and debate the issues of can we break ourselves into five states, can we secede, a lot of interesting things that I’m sure Oklahoma and Pennsylvania would love to be able to say about their states, but the fact is, they can’t because they’re not Texas.”
A Perry spokeswoman said Perry believes Texas could secede if it wanted.
Sanford Levinson, a professor at the School of Law at the University of Texas at Austin, said that between the Texas Constitution, the U.S. Constitution and the 1845 Joint Resolution Annexing Texas to the United States, there is no explicit right for the state to return to its days as a republic.
Emphasis mine. (“thumb their noses”? By doing what, passing something with more votes??? Never mind that…)
But the above wasn’t the first time he mentioned secession:
Rick Perry pulled a Michele Bachmann on Tuesday, passionately condemning a policy that does not actually exist.
This time round it was over farming issues. “If you’re a tractor driver, if you drive your tractor across a public road, you’re gonna have to have a commercial driver’s license. Now how idiotic is that?” perry told a Des Moines crowd. “What were they thinking?”
As it turns out, Perry’s claim is based off a false rumor that was circulating among farmers that the Department of Transportation recently put to rest. The Wall Street Journal reports that the confusion was over a federal review of a proposal by Illinois to require commercial licenses for farmers, but the DOT ultimately concluded — as Perry did — that “the common sense exemptions that allow farmers, their employers, and their families to accomplish their day-to-day work and transport their products to market” should not be tampered with by states.
“We have no intention of instituting onerous regulations on the hardworking farmers who feed our country and fuel our economy,” DOT Secretary Ray LaHood’s said in a statement responding to Perry’s claim.
I would love to see unemployment numbers charted with the tax rate charts. Wonder if any conclusions could be drawn? And I’d also like to see the income inequality against these numbers too…..bet both would say a lot. Re: Perry – I think he’s proving he’s just as outrageous as Bachmann who can’t even fact-check the King’s birthday. I think Perry is stepping out with those cowboy boots in his mouth!
Now Karl Rove is going after Perry; Perry made a statement that threatened Fed. Reserve chair Bernake (appointed by President Bush by the way) and Karl Rove went after him on it.
Grab the popcorn; it will be fun to watch the loons attack each other.
To keep track of my training. I train for ultramarathons (I usually walk these) and sometimes do running races, bicycle rides and open water swims for variety. My best ultra accomplishment was walking 101 miles in 24 hours in 2004. There was a time when I could run a sub 40 minute 10K (did that once), but that was another lifetime ago; these a days 24 27-28 minutes for a 5K would be more like it. I also have an off and on interest in yoga.
From time to time, I post what I am thinking about mathematically
I often post links to science articles, especially articles about cosmology and evolution.
I am very sympathetic to the “new atheist” movement, though some might consider me to be an agnostic. I reject any notion of a deity that interferes with physical events, but remain agnostic to the idea that there might be something “grand and wonderful” (Dawkins’ phrase) outside of our current spacetime continuum.
I am a liberal Democrat who thinks that the current social atmosphere is tilted way too far toward the interests of big business, and I reject the idea that a “free market” cures all ills, though pure socialism doesn’t work either. I am also a believer in the freedom of speech, including speech that I might not like. Also, I’ve been involved (to a moderate degree) with political campaigns, ranging from City Council races up to Presidential races.
Since being targeted by neo-nazis, I’ve started to identify with the anti-racist and the anti-fa movements.
I like to post photos of trips and vacations.
I sometimes blog about boxing matches and football games.

As of March 20, 2010, I went through my longer blogroll and deleted links that no longer work. Be advised that some blogs have not been updated and others have been moved, but you can get to the new address via the old one.
I've read and visited all of these sites at one time or another. However, I've decided to post a separate list of those blogs which I read regularly (some daily, others periodically).
