spontaneous parametric down-conversion

if you shine a light through a certain class of crystal. of course you see the light that passes, but if you examine closer you will see this crystal develops a halo around it if you increase the intensity with the whole spectrum of colours present. this is a beautiful phenomenon but it is actually demonstrating a physical effect. a majority of photons pass through but a very small minority undergoes a bizarre transformation. the minority photons 'break down' into two photons. this is not well understood yet but what is formed is a pair of photons. the photon pairs produced in this way are entangled.

substitute a laser 'pump' as your photon source, using Lithium niobate LiNbO3 or barium borate β-BaB2O4 as your crystal lattice, one can produce predictable numbers of entangled pairs of photon. for every 100 billion or so photons that escape unhindered one will 'down-convert into pairs. {meaning they are bumped down in frequency 'colour' that add up to the original frequenc}). these crystals are known as non-linear crystals because the math used to describe their structure contain squared terms.

so... we have a way to predictably produce entangle pairs of photons for research right on our kitchen tables. no need for accelerators or colliders. the pairs produced in way are not only entangled in polarization {spin} but also in direction.

is that not moogly?

What makes you feel sexy?

¡Mi nuevo automobile!

But seriously. I am sexy all the time, no?

Working for "the man" is hardly the career of choice I'd have given myself had I taken one of those 'where will you be in ten years time?' questionnaires so popular these days. Working for "the man".. especially as "the man" in this case is a most bossy little girl.

No more botanical specimens have been found to work with. Instead, I spent the better part of the day playing plumber, as everything in Silent Hill is in various states of disrepair.Hell, I tell you now, is going crazy trying to fix a toilet. All online help pages say it should be easy, 1-2 hours. The only thing keeping me from ripping the whole thing out and leaving a hole in the floor {hey, they do it in Japan!} is seeing terminology like "spud nut" and "ballcock."

Madre di dios..

The Pitcher plant is a carnivorous plant that I have always been fond of. The sheer design and functions of it are amazing for being just a plant. The new plant has some characteristics in common with it, and that to me is most impressive. By the leaves being in a "pitcher" shape, it can then catch rainwater and hold it inside. The fibers of the modified leaf-stalk contract, thus drawing the end of the leaf down over the opening.

Various small creatures are attracted to the idea of a fresh drink, but once they enter they cannot climb back out and drown. The collected water has anaerobic bacteria that lives in the water that helps the Pitcher plant to digest their prey.

But so much more to worry about than collecting samples of the carnivorous plant, unfortunately..

There was an incident to-day. One of the local girls who had been infected has attacked Señor Snape. We have antidote to give him, but his wound may still become septic. In the meantime the girl is in custody, and we will have to monitor both of them.

Upton, what are you planning? ¿¡Pero qué diantres has hecho!?

Cría cuervos y te sacarán los ojos.

Why, I am given cause to wonder, would anyone want to make zombies in the first place? As weapons go, they are pretty uncontrollable, really unreliable, and had I mentioned contagious? Zombies are quite hard to kill. That said, zombies are dumber than dirt, and usually pretty easy to outrun, assuming you can run somewhere there are not more zombies, of course. While many zombies seem to favour brains, they usually will eat whatever part of your body they can fit in their mouth, and will not really care much if you are still alive while they are doing it. What's really weird? They cooperate with one another. They always seem to form a gang to hunt down any non-zombies in the area without fighting amongst themselves. They must have some kind of secret zombie handshake or pheromone that lets them know who is cool to eat and who isn't. Generally, zombies will stand around until they see prey, at which point they lurch after it, kill it, eat it, and then stand around some more. You can stab them, shoot them, set them on fire.. but inevitably if there are more infected this is bound to lead to more zombies, and the whole problem perpetuating itself time and again.

You have to wonder, really, if there's much of a future as it stands now that the zombies even exist. Their drive to exterminate the human race is relentless and pitiless. The best we can do is slow them down for a while, but eventually I suspect zombies will rule the world.

It sucks, no?

The bees have been dying. Scientists call it Colony Collapse Disorder, which sounds like something curable with a serotonin uptake inhibitor, no?

The bee colonies look fine from the outside, with bees wandering in and out the hive, but when the hives are opened, most of the bees are gone. Not dead. Gone.

I guess I should consider myself lucky, considering the last few times I got stuck inspecting the bees a number of them got in my suit, and I wound up with more stings than I happen to enjoy receiving- for the record, I don't like being stung at all, so any amount is more than I would like.

Much as I know Ashley's friends aren't into bee husbandry for kicks, I can't help but wonder how much of this is about the mead.

Hijo de mil putas, I hope they get sick sometimes, I honestly do.

A small purple microbe that spent more than 120,000 years in hibernation deep beneath a Greenland ice sheet is alive again. Scientists at Pennsylvania State University revived the bug in a lab by warming it in an incubator over the course of 11 months, Scientific American reported.
The bacterium, which was found under nearly two miles of ice, began producing fresh colonies when it was reawakened.

Dubbed Herminiimonas glaciei, the bug is ten to 50 times smaller than E. coli and is not harmful to humans, one researcher told the Daily Mail.
Scientists say the discovery suggests that dormant life could be revived from ice particles taken from Mars sometime in the future.
"These extremely cold environments are the best analogues of possible extraterrestrial habitats," a scientist told the Daily Mail.

GreyhoundBabe wrote: And they needed to warm it up and let it reproduce why? Maybe this particular species of bacteria is harmless.....maybe when it mixes with other bateria or viruses it becomes lethal..... Are they going to use this new 're-awakening' technique on other, possible unknown and dangerous bacterias they may find? Several years ago, they were diigging up frozen bodies of flu victims from 1918.......they could have unleashed that form of the flu again.... Scientists may have book smarts. but many don't have common sense!!!

And.. enough from the peanut gallery.

Herminiimonas glaciei, a Gram-negative ultramicrobacterium (designated strain UMB49T) was isolated from a 120 000-year-old, 3042 m deep Greenland glacier ice core using a 0.2 µm filtration enrichment procedure. Phylogenetic analysis of the 16S rRNA gene sequence indicated that this strain belonged to the genus Herminiimonas of the family Oxalobacteraceae of the class Betaproteobacteria.

Cells of strain UMB49T were small thin rods with a mean volume of 0.043 µm3 and possessed 1 or 2 polar and/or 1–3 lateral very long flagella. The original colony pigmentation was brown-purple but after recultivation the colonies were translucent white to tan coloured. Strain UMB49T grew aerobically and under microaerophilic conditions.

Before Agent Mulder gets back and goes to town with this story I thought I'd present the facts first. Facts help you grow big and strong, you see, children.

The last year cycle of the Mayan calendar does indeed end on December 21, 2012, but the reason for this is less mysterious than one might think. First we have to understand how the Mayans kept time, which is largely more complex than our own. They two systems, but the one of importance is known as the "Long Count", which dates using five values:

Kin = 1 day
Uinal = 20 days
Tun = 360 days
Katun = 7200 days
Baktun = 144000 days

A Mayan date like would be 6 baktuns, 3 katuns, 3 tuns, 8 uinals and 0 days. A full Mayan cycle is 13 baktuns, which means it would end on, which would be 1,872,000 days from the initial date of, or more commonly known as the "Zero Date". Through some crafty archeological work, most experts agree that the Zero Date is August 11th, 3114 C.E. on the Gregorian Calendar.

What's interesting, however, is that the Zero Date was initially of little relevance to the Mayans because their calendar system was based on its end rather than its beginning, meaning that the 2012 date was chosen first, then the cycle was retroactively applied to give the current date.

The Mayans and other Mesoamericans were concerned on many levels the concept of emptiness, death, etc., which may help explain why they were the first to develop the number 0 and have still the only calendar system that incorporates it. Their astronomical observations are often based on the voids between star movements, like the the northern void where Polaris now resides today. 2012 marks the end of another age, but why was this date chosen in particular, if it is to be assumed at all?

The most conventional explanation is that on this date the winter solstice sun aligns through the "dark rift" in the Milky Way galaxy, a rare phenomenon. Why this phenomenon is significant has its origins in Mayan mythology, namely the Sacred Tree, an image heavily referenced in their culture. Astronomically, the Sacred Tree is represented by the intersection of the band of the Milky Way galaxy with the ecliptic of the sun. This intersection is considered the doorway between life and death, among other things.

It must be assumed that the Maya were able to predict the precession of the equinoxes, which is becoming increasingly more accepted amongst archeologists. It's not too surprising, seeing as their calender can be used to predict just about everything else. The relationship between the ecliptic and the Galactic Equator is one heavily referenced in Mayan mythology, so it's not much of a stretch to assume that the Maya would set the end of their calendar to correspond with what they viewed as a significant celestial event.

The band of the sun passing through the dark region in the Milky Way represents a passing through the void, resetting the relationship between the worlds of the living and the dead. What most conspiracy and apocalyptic types fail to understand, however, is that this event doesn't hail the end of the world so much as it is the resetting of the cosmos so that a new age may begin.

All of the above, naturally, is a complete lie.

People are silly creatures. One day they're looking for a guardian angel, the other day they want all angels to die.. why? Well, because ANGELS DESERVE TO DIE, the disgusting self-righteous bastards they are. Autumn, blow me away to the sky, wash me away to the sea, pound me with hail into the ground, or burn me on a cross on the dio de los muertes, I'll take whatever you dish, for I deserve it!

A short lesson of history: animals did not first appear with the Cambrian. The first true animals appeared a short time before the first of the pre-Cambrian ice ages, being descended from one of the eukaryotic slime molds. Like their slime mold ancestors these were very basic worms with no real organs, or even basic structures of any sort. They are called animals because they began as organised individuals, instead of the loose
masses of protiens slime molds begin as. As the eras passed these basal animals changed. Organs appeared as specialized cells developed. As did new structures binding the cells together, imparting new strengths, new capabilities to creatures once restricted to the tube like shape of their forebears.

As time passed their descendents became more complex. Development changed, leading to new phyla. Molluscs, crustaceans, chordates among numerous others. The tight and violent environment they were forced to live in also gave rise to structures the cnidarians could not develop, that of hard parts. Skeletons and plates in other words.

Molluscs developed shells, crustaceans an exoskeleton. While among the chordates appeared the very beginnings of what would later become the vertebrate skeleton.

And in all this, what? The gods had their moment where they had to touch down in all this mess, or so this religion, all religions, have us know. Why would they come to this barren earth? Watching the floor show? A rave review of the primordial soup, what, what? I guess just as I do not understand Umbrella's insidious need to play at being God, I also do not understand this god, the one right here, who we are told will eat this small town, this Silent Hill, whole? and for what? Sense is what I'm seeking here, I guess, I am a scientist. It just seems silly, and no reason to die, all this..

You know that you've been thinking too much about paleontology when you realize that most cladistic terminology could make decent band names. For example: Basal Tetanurae, Tiktaalik, crown clade... yeah.

Anyway. We're going to need more vaccine. That is all.

Obviously the primary purpose for all biotics is their own sustenance, but, as is incident to their living, they are chemically signaling their way through all of existence. The common genetic markers shared by all lifeforms are known to enable the formation of symbiotic relations {communications/cooperation}. Biologists have discovered several examples of symbiotic relations that humans share with micro-organisms. Our conditioned habits and logics must induce the same appetites for our unicellular dependents. If our cells are capable of translating amino and protein based signaling from micro-organisms, what are the limits for the expression of these processes by us as human amplifiers... And further, to what extent have the reciprocators of historic human conditioning and genetic modifications enabled, at minimum, subconscious responses to other amplifiers?

I guess what I am trying to say is right now we are going to try negotiating with the Umbrella people once more. Because the alternative may be too dreadful to contemplate, what with some sort of armaggedon coming or what have you.

Last thing we'd need is more zombies on top of that.
