Just saw some Juncos outside when I was looking out the washroom window. Yet another sign that colder days are upon us.

I really should get some birdseed... it's been awhile since I've just sat and watched my feathered friends.

Oh I remember now... that's the sun!  I saw that the day we left to go on our vacation here in Rainland.  How nice that it has decided to grace us with its presence... on the last day.  Well I'm not going to be cynical today (I mean, after this point).  Clark's Bridge was a bust yesterday... rain dumping down and you have to pay to get in to the tourist trap it is ensconced in... a veritable fortress of phony, brightly-painted, dreck.  So I'm not going back there.  But maybe I can get to the Flume Bridge today.  We'll see.  Either way there should be something to shoot.

Unless it starts raining.

Okay, starting from now, I mean...

Yes I know, first I'm writing about the likelihood of contacting alien civilizations, then I'm talking about immortal humans who have sex for three days straight and write books in their sleep, and then about creepy flickrites, and now I am writing about watching ants.  You don't come here for consistency.

I was leaving my office around lunchtime the other day for a brief walk.  The front of the building has a raised garden with some azaleas and a really nice looking stone wall bordering it.  As I walked out I noticed the wall was swimming in tiny black ants.  Not the big ones you see wondering solo, but hordes of teensy ones.  Usually that means that a tasty food item has been discovered and the colony is out to disassemble it and carry it back.  I could see where the ants were clumped up, but didn't notice anything there that I recognized as anything ants would want to eat.  But I figured maybe somebody had spilled a soda and they were gobbling up dried sugars right off the rockface.  I went off to my walk and didn't think any more about it.

Later that night when I left work, I glanced at the wall and noticed the big cluster of ants was still there, but it had moved a few feet to the right.  Again no food was evident.  Just ants in a big tangled mass.  So I leaned close to peer at them and noticed that ants were bunching up around other ants, and apparently biting each other.  Other ants seemed to be carrying away dead (or dying ants).  I leaned back and noticed that unlike a typical feeding situation where you see a river of ants leading from the colony to the food and back, this was the meeting place of two rivers of ants.  One from one crevice about 5 feet to the left, and another from a crevice about 4 feet to the right.

That's when I realized I wasn't watching a feeding frenzy.  I was watching a war.  It was an epic battle between two colonies of ants that had both claimed this rock wall as their territory.  Thousands upon thousands of ants continually poured from both crevices, and converged in the center to engage in a massive melee.  It was mesmerizing to watch the supply lines bringing in fresh ants as the wounded or the dead were hauled away (presumably as food).  They moved in tides and complex whorling patterns as they made war... it was so intricate it was actually mesmerizing.  I checked my camera bag but I had neglected to bring ANY macro lenses with me that day, or I would have had pictures of all-out insect warfare and abject carnage to upload to my photostream.

It made me a little sad to think of these ants fighting for hours over a few feet of turf.  After 15 minutes I suddenly realized the time and made a mental note to bring my macro lens to work today.

But when I arrived this morning, the battle was over, and the battlefield had been swept clean.  Had I not noticed it, the day before, I never would have known it had happened.  In my inner thoughts I could not help but make the connection between the affairs of the ants and the affairs of humanity.  In 100,000 years, if humans are still here, what great battles and wretched suffering of ours will have passed into the unknown?  Will we forget World War 2?  Will we forget the Holocaust?  Will we repeat it?  Big thoughts from the tragic ant war of June 25, 2008.

Here's a funny animation I caught on Pharyngula, the excellent science blog by P.Z. Myers.  The audio is German, but there are subtitles.  I got a kick out of it, perhaps you will too?

Das Rad

I was listening to NPR Science Friday on podcast a few nights ago and caught an interesting segment detailing a recent discovery regarding bacteria found in soil.  It has been demonstrated (for example, by the discovery of the nylon bug) that bacteria in the presence of an abundance of one substance or another may evolve to be able to metabolize that substance... even if the substance is synthetic.  It's also been shown that bacteria in the constant presence of antibiotics will evolve immunity.

These newly discovered soil bacteria have done both.  That is, not are they only immune to a disturbingly long list of known antibiotics, they have evolved to the point where they can actually eat antibiotics.  The Royal Society of Chemisty has an article on this recent discovery:

[...] The soil samples were taken from many different places [in the USA] including public parks and farms, pristine forest, and land treated with wastewater.

'The increase of multiple-antibiotic resistance in human pathogens is continuingly weakening our ability to fight infectious disease, and any accessible reservoir of resistance mechanisms that could transfer to pathogens could exacerbate the problem,' say Dantas and Sommer.  

So far, the researchers haven't found any known human pathogens among their antibiotic-consuming organisms, but they say that some are closely related species. This might make it rather easy for pathogens to acquire antibiotic-resistance and antibiotic-metabolising genes from innocuous bacteria. [...]

Scary stuff!  But rather unsurprising since antibiotics get into the environment every day through their continued use.

The segment on the antibiotic-munching bacteria was followed by another segment on an alternative form of antibacterial treatment called phage therapy.  Phage therapy, instead of using chemical substances to combat bacteria, uses viruses, specifically bacteriophages--viruses that only infect bacteria.  This sort of therapy was predicted shortly after the discovery of bacteriophages in 1917.  Once antibiotics were discovered (in 1941) phage therapy wasn't pursued further in the west, but continued to be studied in Russia.

The advantage of phage therapy is that the anti-bacterial agent is also a living organism, so as bacteria evolve to become immune to it, the phage species also evolves to continue to prey on the bacteria.  Antibiotics, being chemical compounds, do not evolve, hence eventually bacterial evolution will defeat an antibiotic unless you can rapidly deplete the bacterial population to the point where your own immune system can fight off the infection successfully.  As bacteria with antibiotic resistance can be found in the environment, and people have been infected with resistant strains, there is apparently renewed interest in phage therapy.

No human phage treatments are presently approved in the USA, though the use of phages to prevent bacteria from growing in food have been approved here.  Phage therapy on humans is used in some states of the former USSR, especially Georgia.  In the NPR podcast linked above the scientists interviewed spoke of a patient with a resistant bone infection that was successfully treated using bacteriophages after being told here in the USA that amputation was his only recourse.  Interesting!

Well it's been a little over a year since my Dad passed away, and it's been a sad time.  Work has not been going very well, and it's hard sometimes to stay motivated.  But good things happen too, which cheer me up some.

Dad loved Spring, especially when the birds returned.

Today as I was driving to work feeling a little blue I spotted some red-winged blackbirds in a small marsh still specked with ice.

Spring returns.  Hope never dies.

I really need to learn how to use exposure lock on my camera, then I might not need to do this to my pictures in order to get the sky to look properly exposed.  I suppose this would work better if I shot at the waterline instead of above it, but that wasn't possible in this case, and this modification was an afterthought.  Maybe today at lunchtime I can get out and experiment with exposure lock for a few minutes.

Took this shot while in the (now public) portion of Devens, MA, and contemplating the sacrifices of our military for our nation.  It's a sacrifice we should never squander.  I feel so badly about supporting the Iraq war these days when I think of all the lives lost in it, considering what we've learned in the meantime.  I refuse to "update my rhetoric" and take to heart all the new excuses for our presence there.  I was lied to, but I refuse to lie to myself.  I couldn't call myself a patriot if I did.
