Day Off

As a State employee I have the perk of getting tomorrow off without pay (part of the Furlough Day program to cut budget deficits). I decided to take today off as well, using a vacation day, to make a 4 day weekend.

Yay!

Anyway, I have lots of stuff to do over the weekend- more than I could do in 2 days. We have a guest arriving from out of town- a long-term guest- and we’re turning part of the garage into a bedroom. There is still much to do and she arrives in a week.

Today I’ll just share some pictures, maybe another thing or two.

The pictures below are from National Geographic, they are free desktop images. You can find these and more at this place. Click for full size then right click to save.

This one makes me think the little guy is saying, “What in the heck has happened to my neighborhood?!”

For my next trick- courtesy of Goopymart–

Nature is amazing, eh? This is from the Guardian:

The oldest evidence of a fungus that turns ants into zombies and makes them stagger to their death has been uncovered by scientists.

The gruesome hallmark of the fungus’s handiwork was found on the leaves of plants that grew in Messel, near Darmstadt in Germany, 48m years ago.

The finding shows that parasitic fungi evolved the ability to control the creatures they infect in the distant past, even before the rise of the Himalayas.

The fungus, which is alive and well in forests today, latches on to carpenter ants as they cross the forest floor before returning to their nests high in the canopy.

The fungus grows inside the ants and releases chemicals that affect their behaviour. Some ants leave the colony and wander off to find fresh leaves on their own, while others fall from their tree-top havens on to leaves nearer the ground.

The final stage of the parasitic death sentence is the most macabre. In their last hours, infected ants move towards the underside of the leaf they are on and lock their mandibles in a “death grip” around the central vein, immobilising themselves and locking the fungus in position.

“This can happen en masse. You can find whole graveyards with 20 or 30 ants in a square metre. Each time, they are on leaves that are a particular height off the ground and they have bitten into the main vein before dying,” said David Hughes at Harvard University.

The fungus cannot grow high up in the canopy or on the forest floor, but infected ants often die on leaves midway between the two, where the humidity and temperature suit the fungus. Once an ant has died, the fungus sprouts from its head and produces a pod of spores, which are fired at night on to the forest floor, where they can infect other ants.

Scientists led by Hughes noticed that ants infected with the fungus,Ophiocordyceps unilateralis, bit into leaves with so much force they left a lasting mark. The holes created by their mandibles either side of the leaf vein are bordered by scar tissue, producing an unmistakable dumb-bell shape.

Writing in the journal, Biology Letters, the team describes how they trawled a database of images that document leaf damage by insects, fungi and other organisms. They found one image of a 48m-year-old leaf from the Messel pit that showed the distinctive “death grip” markings of an infected ant. At the time, the Messel area was thick with subtropical forests.

“We now present it as the first example of behavioural manipulation and probably the only one which can be found. In most cases, this kind of control is spectacular but ephemeral and doesn’t leave any permanent trace,” Hughes said.

“The question now is, what are the triggers that push a parasite not just to kill its host, but to take over its brain and muscles and then kill it.”

He added: “Of all the parasitic organisms, only a few have evolved this trick of manipulating their host’s behaviour.

Why go to the bother? Why are there not more of them?”

Scientists are not clear how the fungus controls the ants it infects, but know that the parasite releases alkaloid chemicals into the insect as it consumes it from the inside.

On the subject of Zombies, Zombie nuts!

Saddest photo ever-

Unrelated nonsense-

At the place I work they are hiring a new Superintendent. I know some people who having worked in this place for many years are on the verge of quitting. I just hope this guy lives up to the hype.  I can hardly stand to lose more people who support the good things. So far, all the news is good. We meet him next week.

Bye for now,

-Rick

New Post- still early August 2010

Hodge-podge:

  • is a word used to describe a confused or disorderly mass or collection
  • a “mess” or a “jumble”
  • a type of mutton soup
  • of the Discordians. The Sacred Chao is a symbol used by Discordians to illustrate the interrelatedness of order and disorder. It resembles a Yin-Yang symbol

YOU decide.

Mostly pictures I’ve run across. Some other stuff. Click for big- as per usual.

Better post something before the next full moon

Pete Townsend – There’s A Heartache Following Me

Click when you want bigger size- some of these are biiig. Click sound thingys where they appear. Click click click. This is just for fun. Obviously.

Abandoned- top > down

Sub Base
In a bay on the northern shores of the Black Sea, the Soviet army maintained an elaborate submarine base throughout much of the Cold War. Now a museum, this abandoned submarine base is in the town of Balaklava, Ukraine. One picture.

Detroit
Yves Marchand and Romain Meffre explored some of Detroit’s dying landmarks for their photo series The Ruins of Detroit. As the industrial revolution came to a close and race riots crippled a once bustling city, many buildings throughout Detroit fell into disrepair and eventual abandonment. Three pictures.

Beelitz Hospital
It is rare that a ruin like this should decay so gracefully and without the marks of vandalism. The Beelitz Military Hospital in Berlin is in great condition for a ruin, perhaps for the history it represents. In 1916, a young Lance Corporal Adolph Hitler recuperated here after taking a bullet in the Battle of the Somme during the First World War. One Picture

NYC City Hall Subway Station
Under the busy streets of New York City rests a perfectly preserved monument to that city’s transportation history. The City Hall Subway Station was first constructed over 100 years ago, a part of New York’s earliest underground transport network. It was shut down in 1945, where it lay dormant and untouched until a one night public exhibition on the station’s centennial. Two pictures- present and past.

Ryugyung Hotel
The Ryugyung Hotel in Pyongyang, North Korea is one of the 20th century’s greatest architectural failures. Initially designed as a beacon of progress and power, the Ryugyung Hotel was unable to sustain construction when the North Korean government ran out of money. Ground was broken in 1987, construction was halted in 1992. One picture.

Pripyat
Pripyat, Ukraine. In a span of sixteen years, the population of Pripyat grew from zero to 50,000 and back down to zero, following the greatest nuclear power disaster in human history. Pripyat was billed as an atomic city, built into the forests south of Kiev in 1970 to house the families of workers at the Chernobyl nuclear facility. One picture (but you can gopogle many others).

Waterpark
A massive, indoor water park was planned for the children of Russia, one towering many stories high with a myriad of rides within. Before this park could be completed, the developer went belly up and couldn’t afford its completion. One picture.

Sea Forts
During the Second World War, the British Royal Navy constructed a series of sea forts for an advanced line of defense against inbound air raids and potential sea invasions from the Axis powers. The Maunsell Sea Forts still stand today, abandoned a few meters above the North Sea. One, however, remains inhabited, now a nation of its own referred to as the Principality of Sealand. These sea forts are a favorite of maritime explorers. One picture.

The following is a short story by the American novelist and short story writer Sherwood Anderson (1876-1941). It was included in The Best American Short Stories of the Century (John Updike-Editor)

“I am in love with my wife,” he said–a superfluous remark, as I had
not questioned his attachment to the woman he had married. We walked
for ten minutes and then he said it again. I turned to look at him. He
began to talk and told me the tale I am now about to set down.

Small post

It’s Sunday night, I’m tired and still want to share a couple things.

First, Update on Blizzard, our cat that had her eyes removed (surgically) because she was suffering from glaucoma. She’s doing exceptionally well. Wayy better than when she was going bind from the glaucoma. She gets around the house without any difficulty, hardly ever uses the walls to roam the place. One of these shows her eating with her sister Annie.

A great little short story:
