That would be PZ Myers, apparently. I had to laugh REALLY hard at that one.

What about those "so-called" professors who only study little bacteria? Poor microbiologists, for they shall never become real professors! =(

Another gem:
"All of the monkeys ain't in the zoo; the rest are at the University of Minnesota. Even more illuminating is that all the assholes are there too, not to mention the bigots, frauds, perverts, and no-nothings. I think that pretty much covers the spectrum in the educated imbeciles category. But, you stand out a little more than others."
Who knew -- the entire world's population of assholes is conveniently compressed into the University of Minnesota. So that's why I've never seen any assholes before -- they all reside in Minnesota! I guess the author of that note also teaches at U of M? Hmmm...
The Official Creationist Worldview Professional Certificate
Just came across this on Pharyngula:
"They also have a distance learning program in which you can get an Official Creationist Worldview Professional Certificate" Yes, apparently such an abomination exists. From the site:
"The Creationist Worldview is an innovative program of study designed to equip current and future Christian leaders with practical tools to effectively influence their world with the truths of Scripture. A formal science degree is not required, and those who can benefit from the Creationist Worldview program includes, but is not limited to, Christian men and women who hold various positions of influence within the community, educators, ministers and church leaders, business and industry experts, professionals in medicine and law, government officials, leaders in the fine arts, and high school and college students."
OH MY FLYING SPAGHETTI MONSTER, a formal science degree is not required to study creationism? Shocking indeed!
And their curriculum is sad and amusing simultaneously.
Sigh. Why do these people exist so easily, whereas if you want to retain integrity and sanity you may be subject to harassment and BS? We actually have to work to get where we want -- these cretins make a whole giant industry just by lying...cr

A rant on pluralism...
Perhaps it really does seem thus far that I'm obsessed with have a research interest in protistology. Unfortunately, I don't have too much time to discuss much else at the moment. Perhaps around midterm time I'll hang out here more, due to alotting more time to procrastination. I can be surprisingly productive during exams, accomplishing a multitude of trivial crap with a blatant omission of study time.
I could rant about that Sarah Palin cow, and her interview of epic fail , but it's a bit depressing, so I won't. Actually, it's mildly terrifying...
Actually, this past Friday I had the opportunity to attend a discussion panel on the integration of sciences and humanities, starring Prof. Steven Pinker (which is the main reason I went...), Richard Shweder and Steven Stitch. Prof. Pinker's talk was awesome, as expected; however, since praise and agreement rarely constitute good writing material, I'd like to share with you the following piece of verbal bowel movement produced by the Shweder guy:
http://www.sci-hum.pwias.ubc.ca/media/pdf/Shweder_prep.mat.II.pdf
His talk was read off a paper pretty much identical to that one, albeit with all the condescending intonations perfectly intact. Though I shall concede that excessive use of Latin-English pidgin does a great job at obscuring vacuous inanities. Unfortunately, too many in the humanities practice this sly art, thereby sadly undermining the rest of the field of any credibility and respect. Examples include postmodernism and the Sokal Affair. Another thing those pidgin Latin fetishists tend to obsess over is contempt towards anything materialistic and scientific. They are fairly wise to do so -- for in proper rigorous 'materialistic' inquiry lies their demise.
I must admit that I had tremendous difficulty following Shweder's talk, even though the two other speakers were very clear and easy to understand. Shweder relied extensively on -isms of all sorts to obfuscate his point further. Essentially I think he was trying to convey that sciences and humanities could never be reconciled because they 'lie on different ontological planes' -- i.e. there some sort of different metaphysical 'realities' of the body, mind, morality, and beyond. And apparently those metaphysical 'realities', whatever they're made up of, are separate, and cannot be examined by the 'monist' methods of inquiry.
Shweder went on and on about the apparent mind-body duality, claiming it is impossible to unify the two, and going as far as criticising collegues for not having read some ancient work of Déscartes himself. I admit I've never even heard of that book; and old writing is practically in a different language from its modern counterparts, thus I'll pass on the commitment to digest archaic French. We do not yet have a clear understanding of what consciousness is, but I insist: when we do, that understanding will be wrought by psychologists and neurologists rather than philosophers!
So then he went on this childish tantrum against 'materialist monists' (I guess I would be one?) and filled the room with enough straw to sustain a small pastoral tribe for a year. Essentially, he accuses us of 'arrogantly' dismissing the worldviews and ideas of the 'natives' and their 'realities'. And yes, he called the traditional tribal people 'natives', possibly implying we don't fall under that category somehow. Please, I'm a native of Russia. Does being white deny me of the privilege to consider myself a native now?
That, to me, is true arrogance. This "oh they don't know any better so let's pretend we believe in their silly games" attitude of most cultural relativists towards fellow humans. Do they seriously feel sorry for the people and assume they're intellectually impoverished, thereby deserving some special sanctum in our ontology? In One River Wade Davis quotes Lévi-Strauss saying "The people for whom the term cultural relativism was invented, have rejected it." (p.290) For some reason, those people don't think they ought to have a special 'ontological realm' for themselves; they see the rest of us as part of theirs.
Perhaps it's the 'pluralists' and cultural relativists who are dismissive and condescending towards differing worldviews? We at least try to comprehend and integrate their knowledge and wisdom in our worldview; albeit there's much improvement to be had, we don't shove them into some separate 'ontological reality'!
Furthermore, why bother creating separate realities when one is more than enough to deal with? Shweder starts off with a quote by Woody Allen: "“Can we actually ‘know’ the universe? My God, it is hard enough finding your way around in Chinatown”, alluding to the common argument that since science cannot know everything, there must be an alternative realm of metaphysics/energy/deities/spirits/woo . So why then, Shweder, are you trying to create a second Chinatown to navigate simultaneously, if one is hard enough?
I agree with anyone who says science cannot solve everything. Scientific inquiry has its limits. Eerily enough, so does the human mind itself. But if even the scientific method, the most powerful tool of acquiring and verifying knowledge we have, is limited in understanding the universe, how can blind belief systems work any better? The underlying principles of the scientific method, I insist, are innate; and have been selected for throughout the millenia of our existence. One who failed to make an accurate prediction was overcome by someone who succeeded. One who fell victim to unverified personal assumptions was on the losing side of competition.
Now we have this data acquisition method, which is far from completion or perfection, that has so far been the best tool we have. We use it on a daily basis -- some more aware of it than others. And as of any other naturally evolved instrument, we must be aware of its strengths and weaknesses, and try our hardest to compensate for the latter. This is where the formal scientific method comes in. Training as a researcher demands a good understanding of how our mind can fail. We extensively use statistics for precisely that reason -- we must have a way of checking and correcting for errors in our reasoning.
One of our bad glitches is the attachment we tend to share with our pet ideas. This blocks the self-correcting mechanisms of skeptical inquiry and sends one straight into the clutches of dogma. The further one strays from the sensical path, the harder it becomes to correct the course, due to the growth of emotional attachment. This is precisely why dualism (and pluralism) are, in fact, dangerous.
You can probably imagine by now an obvious example of dualism -- religion. Many religious people tend to separate the world into the physical, and the spiritual. It seems harmless, but renders the victims vulnerable to manipulation by those with alterior motives. Many are willing to die for their religion, and can be persuaded to commit a plethora of hideous acts. Reason cannot speak to these people, for they can create a sanctuary from logic in their alternative realities. 'I'm killing people to serve God, for it is God's will for these people to be killed' makes perfect sense if the related religious stories are perceived in the mind as reality. Suicide bombing makes perfect logical sense in the mind of an Islamic fundamentalist. Killing doctors makes perfect logical sense in the mind of a Christian anti-abortion fanatic. If we assume they are all right in their own way, we will have sheer chaos! Dualism (and pluralism) is dangerous!
On the first page of his talk, Shweder compares E.O.Wilson's Consilience: The Unity of Knowledge to a "monotheistic sermon". Prof. Wilson, the great sociobiologist and entomologist, is apparently a preacher. If so, then I hope I have convinced you, dear reader, that Shweder is a full-out religious fanatic.
After the talk I had a burning urge to pick a vicious fight with Shweder, but decided 5 min of conversation with Prof. Pinker would be worth a few orders of magnitute more than arguing with an arrogant, empty, fanatical academic. It definitely was! =D
And now that I've had a wonderful evening ripping apart some high-ranking academic, sleep is in order.

Sunday Protist -- Diatom
When UV light bounces off chlorophyll, the frequency is shifted towards red (fluorescence), which can be safely picked up and observed through a UV filter. What is awesome about UV work is that you can view it simultaneously with our own spectrum, since we don't notice when UV light is filtered away. You can't do the same with substances whose excitation frequencies (the incoming colour that later changes) lie within our visible spectrum, since you have to filter out a band of colour - making the filtration pretty obvious. Thus, you can't simultaneously view GFP (green fluorescent protein) and normal light, since you'll have to filter out everything but green, which is the emission frequency (the resulting colour).
Fluorescent microscopy is a powerful tool in cell biology, as it enables one to "colour" certain proteins, and find them via fluorescence. You can do live cell imaging with that, and observe real cellular processes in vivo, as well as creating time-lapse (movies) and stacks (3-D reconstructions).
I wish people were taught about real cells in school, as opposed to that hideous textbook thing (which does NOT exist -- there is no 'typical' cell!) Cells are so alive and dynamic and exciting...all that gets thoroughly lost in those cartoon diagrams. Can't we provide highschool educators with our sexy movies of real cellular phenomena in action? Should be cheaper than textbooks themselves! And much more informative, not to mention memorable!
Now back to our diatom. Since UV light is converted to red upon hitting chlorophyll, what does the image stack tell us? Well, you can see certain compartments emit this red light, indicating the presence of chlorophyll. You may or may not have heard that diatoms are phytoplankton, meaning plant-like plankton. They are actually not particularly close to plants at all -- diatoms are brown algae, the ancestor of which has engulfed a green alga at one point, and incorporated it as an organelle. As a result, the chloroplasts in diatoms have two extra membranes around them, coming from the original green algal host. This is called secondary endosymbiosis -- a host engulfed a host of a cyanobacterial descendant (chloroplast)!
There's also tertiary endosymbiosis -- a host engulfing and host of a host of a chloroplast. Some of things have an extreme number of membranes layering each chloroplast.
I'll discuss endosymbiosis in more detail at a later day, but back to our diatom. I'm a bit dense, so it took me a while to remember that diatoms are phytoplankton, for they don't particularly look like plants or green algae -- they're not particularly vibrantly green like the green algae. But playing around with our UV lamp after a whole day of DAPI imaging (to see nuclei in plant cells), I threw on some seawater samples on the slide, and got views like the following:
And that little thing with a tail near the top may be a dinoflagellate of some sort, perhaps. Catching those things with a camera is nearly impossible...they like to move!
Anyway...most diatoms you find tend to be empty shells, as opposed to the live organism itself. So you often forget that they are in fact photosynthetic. I think the autofluorescence drives that point home quite well. Now we remember. Also, you could possibly identify plastids based on their autofluorescence emission, but I'm not sure how it's done yet... that would be topic for another day.
Another cool thing about diatoms -- when they divide asexually, the top shell separates and forms a bottom, which is smaller than the top. The bottom shell becomes...the top, and forms and even smaller bottom. Consequently, several generations later you end with a population of very tiny diatoms, so they have to somehow get bigger again. So they enter the sexual cycle, fuse and dissolve their old shells entirely, forming a new, large, pair upon separation. That's why you find a gradient of sizes within the same species.
Happy diatom worship!
And then it suddenly... EXPLODED!

Sunday Protist - Labyrinthulomycota
Cute little marine protozoans that run around through 'tunnels' of their ectoplasmic net. Featured above are Aplanochytrids, which glide along the ectoplasmic net without being enrobed in one. (Leander at al. 2004 Eur. J. Prot.)
(http://www.botany.uga.edu/zoosporicfungi/labyimages.htm)
On the other hand, labyrinthulids (above) travel right through the ectoplasm they secrete. They form those elaborate nets they crawl around and use to catch floating debris/prey.
Biblical Microbiology
This randomly popped into my head while I was doing E.coli transformations today:
(From: Microbius 1:01-1:33)
01
She sayeth onto the chosen Tribe of E.coli
"Taketh upon thee my Holy Construct,
For it shall heal your soul and spare thee from the devil."
And she blessed the great tribe with a heat shock,
Hoping to instill faith within them for all eternity,
Faith in her Holy Construct.
But some E.coli refused the Holy Construct,
Preferring instead to believe in their own pagan plasmids,
Neglecting the holy plasmid of God.
This insolence angered Her deeply,
11
And her neurons fired in wrath,
And She inundated the E.coli culture
With a great Flood of hygromycin;
And thus were smote in fiery wrath,
The heathens who failed to place faith in the Holy Construct.
And from the Flood their souls unsaved,
For they have not receiveth the Resistance Gene.
And lysed their membrane were in hell,
Damned to an eternity in the autoclave.
And She sayeth onto the good E.coli:
21
"Get thee to my pipette tip ark,
And I shall carry thee to the land of plenty,
And ye shall call this land the Test Tube,
And may the LB broth save ye from starvation."
She commandeth to the good E.coli:
"And while ye flourish on my sacred LB,
Dare not forsaken my next commandment:
Be fruitful and multiply,
For in a forthnight ye shall find thy souls,
Preserved in -20C heaven, in a stock of glycerol,
31
And blessed thy genomes shall be Saved,
As my Holy Constructs is delivired to the Holy Plants,
In the Growthchamber of Eden."
RAmen.
May your DH5α be forever blessed! =D
(And GV3101 as well; why not?)
Yes, the Growthchamber of Eden has GFP-expressing plants. The sun shines 488nm wavelength there. No wonder it's so green, eh? You should, like, totally see the tubulin:GFP-expressing tree -- it's a freakishly fluorescent green cytoskeleton! And the Forbidden Fruit is forbidden due to being stained with DAPI -- DAPI is bad for ya, y'know?
This is getting out of hand...I think I need to get out more often or something ^_~

21st Century -- The Battle of the Memes
It seems the 21st century will oversee a climactic decisive battle of memeplexes. We are entering the era of violent clashing between fundamental ideologies both new and old. The ones with the most succesful highly viral memeplexes will win.
Take a look at this clip there: http://richarddawkins.net/article,3121,n,n
(this reminds me strongly of the terrifying documentary Jesus Camp)
Look at those people involved. Look at their convulsions, both physical and verbal. Are these people sane? Are they normal?
I maintain that those fanatics are, in fact, perfectly normal people. However, they are also batshit insane. The point to stress is the fanaticism and madness do not arise due to some fault or blemish in those particular people -- the insanity invades perfectly normal minds, much like a cold invades normal bodies. For whatever reason, the viral ideas of their particular church happened to invade their minds at a vulnerable time. These viral memeplexes are now gradually gnawing away at the victim's brain, modifying them to suit the needs of the memeplex itself -- much like the Cordyceps fungus chemically alters the victimised ant's brain to force it to go high up and cling to a twig, while the fungus kills it and sporulates from up high. The Cordyceps is truly a terrifying parasite for the ant it preys on.
And that is the terrifying part. Genetic illnesses, although sad and grotesque, do not terrify the rest of us lucky enough not to have them -- for they cannot spread upon contact. Viral epidemics, however, are terrifying -- even mild sicknesses like colds. Furthermore, when an ant is infected by the Cordyceps, other workers of her colony carry her as far away from the nest as possible, and even remain there to die themselves to spare the colony from infection. Some of our parasitic memeplexes have an even better strategy, however. They modify the environment around the affected to disable any potential ostracism of the victim. The parasite portrays itself to the outside as benign, thereby escaping much of the scrutiny that would otherwise bring forth its end. And there are more potentially vulnerable individuals to come in contact with.
This brings us to a rather interesting way to model and analyse many of the world's events: Human minds are highly malleable, regardless of how much we try to resist. We are much like the molecules a DNA molecule uses to perpetrate itself to the future generations -- they may be thermodynamically resistant to such enslaving, but the genes that have mastered the technique are highly succesful in continuing it further (the other genes just die.) The memes use us to live out their own evolutionary stories, and manage to enslave humans to behave at their whim. Nationalism, political ideology, religion - look how many human lives were lost to the fierce battles between them! Humans are trashed around like socks in a washing machine: innocent, vulnerable people simply trying to live can be converted into vicious irrational killing machines ready to destroy the others who are exactly like them -- albeit parasitised by a different ideology.
This view places no blame on the common folk who are parasitised, regardless of how vile their crime. They were weak, perhaps mentally unhealthy for whatever reason. They became sick. Now their sickness imposes its raging symptoms upon the lives of others.
There are the smart crooks who take advantage of these ideologies, and despite not being aware of the formalisms of memetics, are masters of the field. To the disadvantage of the rest of us, of course. Some of these people are politicians, people of great power. Many of those politicians are parasitised by vile memeplexes as well. Now that is truly scary, for the ideology can express itself to its fullest foul capacity.
The destructive ideologies are evolving along with the beneficial ones. They're getting better and better at what they do. And perhaps this century may be an age where their battle rages greater than ever before.
I'm afraid the only way to combat this would be to launch a memeplex as a counter-offensive. Some benign ideology that self-destructs after a certain timeframe, immunising its victims from future viruses that may not be so benign. Basically, memetic vaccination. The child's mind is particularly malleable, and must be protected from diseases by a proper education.
We face today a slippery slope downwards from anything that can be even marginally considered 'proper education'. Perhaps we are at the lowest level of education and social intelligence in many centuries. Perhaps we have never been as dumb, naive and gullible as we are now, especially in the west. This compounded by the fact that never before have the ideological diseases been so good at what they do, is a very scary detail. I am genuinely worried. And terrified.
We should be careful not to attack the inflicted, but rather attempt to cure them of the infliction. Of course, many of them view us as inflicted (in the religious sense; we definitely all are inflicted by one thing or another in other ways), and that is one advantageous adaptation of their parasite. Imagine a viral disease that made you feel great and also feel the need to spread it to everyone else! If such a virus ever evolved, even if it killed off the host in drastic manners, it would thrive!
Well, that virus is here. It's been here for millenia, and is now more advanced than ever before.
We are on the losing side. Let's get our acts together and spread the antidote of skeptical rationalism as well as awe and adoration of that which truly is, as opposed to that we wish would be. If we wait much longer, it might be too late...

Furthermore, when an ant is infected by the Cordyceps, other workers of her colony carry her as far away from the nest as possible, and even remain there to die themselves to spare the colony from infection. Some of our parasitic memeplexes have an even better strategy, however. They modify the environment around the affected to disable any potential ostracism of the victim. The parasite portrays itself to the outside as benign, thereby escaping much of the scrutiny that would otherwise bring forth its end. And there are more potentially vulnerable individuals to come in contact with.
This brings us to a rather interesting way to model and analyse many of the world's events: Human minds are highly malleable, regardless of how much we try to resist. We are much like the molecules a DNA molecule uses to perpetrate itself to the future generations -- they may be thermodynamically resistant to such enslaving, but the genes that have mastered the technique are highly succesful in continuing it further (the other genes just die.) The memes use us to live out their own evolutionary stories, and manage to enslave humans to behave at their whim. Nationalism, political ideology, religion - look how many human lives were lost to the fierce battles between them! Humans are trashed around like socks in a washing machine: innocent, vulnerable people simply trying to live can be converted into vicious irrational killing machines ready to destroy the others who are exactly like them -- albeit parasitised by a different ideology.
This view places no blame on the common folk who are parasitised, regardless of how vile their crime. They were weak, perhaps mentally unhealthy for whatever reason. They became sick. Now their sickness imposes its raging symptoms upon the lives of others.
There are the smart crooks who take advantage of these ideologies, and despite not being aware of the formalisms of memetics, are masters of the field. To the disadvantage of the rest of us, of course. Some of these people are politicians, people of great power. Many of those politicians are parasitised by vile memeplexes as well. Now that is truly scary, for the ideology can express itself to its fullest foul capacity.
The destructive ideologies are evolving along with the beneficial ones. They're getting better and better at what they do. And perhaps this century may be an age where their battle rages greater than ever before.
I'm afraid the only way to combat this would be to launch a memeplex as a counter-offensive. Some benign ideology that self-destructs after a certain timeframe, immunising its victims from future viruses that may not be so benign. Basically, memetic vaccination. The child's mind is particularly malleable, and must be protected from diseases by a proper education.
We face today a slippery slope downwards from anything that can be even marginally considered 'proper education'. Perhaps we are at the lowest level of education and social intelligence in many centuries. Perhaps we have never been as dumb, naive and gullible as we are now, especially in the west. This compounded by the fact that never before have the ideological diseases been so good at what they do, is a very scary detail. I am genuinely worried. And terrified.
We should be careful not to attack the inflicted, but rather attempt to cure them of the infliction. Of course, many of them view us as inflicted (in the religious sense; we definitely all are inflicted by one thing or another in other ways), and that is one advantageous adaptation of their parasite. Imagine a viral disease that made you feel great and also feel the need to spread it to everyone else! If such a virus ever evolved, even if it killed off the host in drastic manners, it would thrive!
Well, that virus is here. It's been here for millenia, and is now more advanced than ever before.
We are on the losing side. Let's get our acts together and spread the antidote of skeptical rationalism as well as awe and adoration of that which truly is, as opposed to that we wish would be. If we wait much longer, it might be too late...
Sunday Protist - Tetrahymena thermophila
(from Wikipedia)
( Robinson R (2006) Ciliate Genome Sequence Reveals Unique Features of a Model Eukaryote. PLoS Biol 4(9): e304 doi:10.1371/journal.pbio.0040304 )
Tetrahymena thermophila (fluorescently tagged, of course).
It's an aquatic cilliate -- a microscopic organism covered in little hairs (cilia) it uses for swimming.
Those creatures have two types of nuclei -- the micronucleus which is the germline, and the macronucleus which is used during the organism's everyday life (ie. somatically expressed). Upon conjugation, the old macronucleus is destroyed and the micronucleus is doubled, with one of them being modified into a macronucleus. The macronucleus genome is then duplicated multiple times -- up to 45 copies -- and the non-coding DNA is spliced off. (http://www.ciliate.org/genetics.shtml)
What a brilliant strategy: keep a copy of your genome safe and unmolested by transcription enzymes (in order to actually use it to make proteins), and have another copy amplified and optimised for everyday use.
Image you had your favourite film on a VHS tape (those ancient casette things, in case a reminder is needed!). Every time you play the tape, you damage it little-by-little, eventually ending up with loads of scratches and poor sound quality. Now you need to copy the film for a friend. The scratches will still be there when you copy it, since that particular data is permanently lost. You friend watches it few times, and the next copy is even more damaged. And so on.
So that the data is not completely lost, you can build some mechanism that edits and fixes the tape each time you play it. It notices the minute scratches, and patches those holes in the data while it can still guess what must be there. This mechanism would be fairly expensive, difficult to set up, and prone to malfunctions. This is what we animals do. Also, we have millions of cells, most of them not in the germline (ie. will not be passed on to the next generation). Mutations in those cells are usually benign and don't matter in the long run (even cancer itself is not transmitted to the next generation; although susceptability to it may be). We try to protect our germline DNA to the best of our ability, albeit in a very unnecessarily complicated, inefficient way.
The poor little Tetrahymena doesn't have a place for germline cells to be stored. Everything must be enclosed in one cell. And it's a bit too small to experiment with low efficiency complex strategies. Every joule of energy counts in its life.
When you first get your film, you could also make a copy of it right there, lock it away in a cupboard somewhere and use the other at your discretion. Hell, you can even keep it out of the box if you'd like -- if you damage it too much, you can always make a copy of the one in the cupboard. If a friend comes to you and asks for a copy of the film, you just make them a copy of the cupboard one, so the damages you've inflicted on your viewing copy do not propogate any further. Your friend also makes a viewing copy and a storage copy.
That's exactly what the Tetrahymena does. It leaves a copy of its genome for storage, locking it away in the micronucleus. The other copy is optimised for reading and is later destroyed upon conjugation.
In a way, that's kind of what we do, albeit in a rather complicated manner. Once the zygote is conceived, the male's somatic cells can all but disappear. We don't care if he dies. Oh, and after gestation and childrearing, the female can die too. Your gonads are micronuclei; the rest of your body consists of macronuclei.
Yet another example of convergent evolution between multicellular and subcellular structures?
Tetrahymena has more cool features, but I'll leave them for later. Since Tetrahymena is a convenient model organism, I'll probably return to it quite a few times.
-----------
RETRACTION(18.08.2009): The tangent about the 'adaptive advantages' of nuclear dimorphism is fundamentally flawed and therefore retracted. The reasoning is backwards, and ciliate nuclear dimorphism is in fact a testament to the generation of complexity by neutral forces. The micronucleus is almost completely packed with transposons and other toxic DNA that must be excised for proper nuclear function. Most other life simply takes better 'care' of their genomes...
Cypress Bowl Mushroom Foray Part II: Slime Moulds
We found about 5 species of slime moulds on out foray. Unfortunately, as explained previously, I fail at remembering names. I'm a cell biologist. We only know model organisms... ^.^
Again, photos by Achiru.
A very common species -- Physarium sp. -- same one as in the older slime mould entry.
Still can't figure out what kind this is...
This, apparently, is also a slime mould. It looks like someone rolled up balls of gum and stuck them on a log... (Lycogala epidendrum - thanks, Emma!)
I think this is Ceratiomyxa sp.?
So yes, I found a very useful site for looking at hawt sexey pictures of slime moulds, and also for their identification: http://pick5.pick.uga.edu/mp/20p?see=I_UARK/0001
And that made me late for Ecology...gotta run!

Cypress Bowl Mushroom Foray Part I: Fungi
Yesterday Achiru and I tagged along with a bunch of fellow fungus/slime mould/botany freaks on a hike up Mt. St. Mark (I believe) in Cypress Bowl part on the north shore. The frequent stops to admire some of Earth's little aliens at the beginning were soon followed by a grueling hike to the top. Grueling, at least, to someone who tends to live in the lab, and cyberspace.
Since there's lots of pictures, I'll split this up into three parts: Fungi, Slime Moulds, and Views + Misc. Appologies in advance for my failed attempts at retaining taxonomical data -- I cannot remember all the names, whether scientific or common, to save my life. Seriously. I SUCK at taxonomy. I think it's a bit overrated anyway, but that's a rant for another day. So I'll just use whatever I've remembered of some of their common names, or just refer to them descriptively. Even mycologists have coined LBM - Little Brown Mushroom. I think that's a valid taxonomical categorisation. It makes life easy for me. Maybe because I'm not a mycologist...
(again, photographs by Achiru)
L - Jelly fungus R - Bird's Nest fungus with an unexploded spore capsule
L - Forgot the name...but really strange black mushrooms! R - Witch's Cap mushroom
L - Bracket Fungus (Polypora) R - guttation on a bracket fungus - water droplets secreted by the actual mushroom, not condensation as dew droplets.
Some cup fungus ( ascomycetes)
That's all for part I, I'll put the residual fungi in part III as I have to run...

A post of filth
Have to run to class soon, but feel as if I should drop in my two cents on the politics of the Land to the South (i.e. US), since everyone is yapping about it.
I'm definitely not a fan of politics, and will not dedicate excessive keystrokes to the subject. It's all a sticky tangle of lies, self-interest masked by a false concern for the electorate, more lies, even more lies, and (with appologies to slime moulds), filthy slime. Republicans are abysmal, but the Democrats aren't far behind. Obama is what we call in Russian "проходимец" -- someone who slithers his way around any situation, usually in a dirty cheating kind of way. I won't even think about the alternative -- not a healthy way to start one's morning.
So in a way I could just say I don't care, and move on with life. Like your average exemplary citizen of a democratic society. But on the other hand... I'm innately selfish (and so are you), so there's certain issues that mean a lot to me, even to the point where I'm compelled to follow at least a little bit of the foul political sewage. One of those issues, for me, is science.
Back around the 60's, US used to be an amazing place for science and engineering. There was good science education in the compulsory school system, good universities, plenty of funding, and most imporantly, a pretty decent rapport between science and the public. People respected what science brought, and had great interest in it. Same thing on the other side of the sea in the USSR: good education, good science fuding, good public interest. Scientific advancement thrived. Religiosity was kept aside in the quiet, letting people do their jobs safe from bullshit ideologies, for the most part.
Then something happened. The public stopped caring much about science. Scientists became viewed as something of pure evil. Science education plummeted. Religion triumphed. Education eroded away further yet. We get creationists. Research funding is on a steady decline. Despite the ever-growing gap of knowledge we see before us (each scientific advancement reveals more and more of how much remains unknown), work in the field is made more and more difficult.
People feel some obscure right to impale others with their oft ill-founded moral convictions. "I believe abortion/gay marriage/stem cell research/atheism/cracker desecration is bad, therefore no one should be allowed to do it." They start demanding the government to achieve their goal of submitting everyone around the, to their own personal beliefs. They start infiltrating the government. Then we get Louisiana, with an approved stealthy creationist bill to pressure science. There's many of them. They have power. REAL power. They have money.
They have infectious memeplexes on their side.
At least the Democrats are a little itty tiny bit potentially more liberal than the Republicans, and the general agreement in the scientific community is that Obama might cut NSF funding a little bit less than his competitor. If the Republicans return to helm yet again, more money will be dumped into the pointless stupid war in Iraq in the midst of a recession at home, and science will be assaulted both in schools, and in the budget. As soon-to-be grad student, post-doc, etc within the next 15 years, with the possibility of starting my own lab eventually, some day... I'm worried. As a human who sees the dangers of dogmatic faith devoid of any self-correcting mechanism, I'm frightened.
Fundamentalism is not funny. Any sort of it -- be it nationalism, political dogma, religion, some school of philosophy -- is dangerous and degrading to the collective human intellect. Yes they say amusing things, but I can't read them without feeling a mixture of fear and sadness. We find them funny -- they believe they're right. And they have power.
I've heard somewhere that the 21st century will be an era of fundamentalist conflict, both in the Christian and Muslim worlds, and also in terms of nationalism. With the vastly overgrown human population that exceeds the carrying capacity (at least that of psychological sanity), the world is growing more and more competitive and desparate. When people are desparate and threatened, they form tightly-knit groups of similar kin. Religions pray on that -- that's how the memeplexes thrive. Some clever people surface and use these factions to their own advantage, abusing the frightened people convived in their superiority. You get violence, be it ethnic or sectarian tension...or something bigger.
If those people were not united by a conviction of superiority, they would probably be substantially less receptive to arms. If the people were less threatened and desparate, they would be unwilling to fight. One doesn't need much to feel unwilling to fight -- a home, a family, some food...and general political stability. Wealth is irrelevant. We have too many destitute wanderers furious at their past. That is a volatile environment -- not to be ignored. But solving this problem requires long-term thinking -- something capitalism, at least in its Western execution, fails at. One only cares about a couple financial quarters ahead, few bother with looking beyond that.
I think a new political party is in order down south. The Rationalists. Definitely would be a hit... (not). Ah well. Time to work on counter-memeplexes to the creotard filth...

Back to chaos!
I came back a couple days ago, but failed to blog due to excessive chaos of the first week of school. Busy busy busy...
Hopefully I'll have more time to blog little pieces by this weekend, when I should make a proper post with some intelligible content. At least try to.
I do have to share some amazement though from a first class I had yesterday: in my Protistology class, which consists mostly of biology major 4th years, most of them didn't know what a...protist...was. Generally, when I sign up for a course whose title eludes me, I'll employ my dictionary search powers and look it up. Apparently that ability dies down by year 4 of university. Also, people who have specialised in biology for four years should generally like...be moderately aware of the kingdoms outside their immediate concern. General knowledge. An animal cell physiologist should remain informed about plants, fungi, eu- and archaebacteria, as well as protists. You know, just as a physicist studying EM should have at least a vague idea about optics and mechanics; an organic chemist should know the basics of the transition elements; a carpenter should know approximately how the plumber and the electrician need to work after him, etc. General knowledge. Being reasonably curious and informed.
Oh wait. I forgot. They're just there for a degree. Right.
And they have better marks than me.
I just wish my peers in science were actually interested in the subject, rather than blindly memorising their way through. A healthy dose of curiosity is good for everyone, but essential for work in science.
