Re:so the story goes
From UT Austin: On the Cusp of an Ebola Vaccine
Bush built that lab (Galveston National Laboratory) as part of the $5 billion Project Bioshield Act of 2004, one of two, the other being at Boston University Medical Center. These are the places where actual research on ebola, dengue, hemorrhagic fever, SARS and others has been happening for years while you perfected your Bush derangement syndrome narrative.

Re:Health effects in children
Then the Nagasaki study is wrong.
http://www.utmb.edu/otoref/Grnds/Thyroid-Nodule-2001-01/Thyroid%20Nodule-2002-01.htm
One of the most widely cited epidemiologic studies involves the population study of Framingham, Massachusetts. In this study palpable thyroid nodules were found, in adults between 30 and 59 years of age, in 6.4 % of women and 1.5 % of men. Additionally, the nodule accrual rate was found to be 1.3% at 15 years, or an annual accrual rate of 0.09%. However, the prevalence is much higher when assessed by autopsy, palpation at surgery, or by ultrasound. Mazzaferri pooled a number of studies and found that the prevalence of nodules by these methods is approximately ten times that of the prevalence by physical exam17. One autopsy study noted nodules in 65% of men and 80% of women in the ninth decade.
It is not possible to have 0 rate, unless the study was very very tiny or wants to claim that "Japanese are perfect". Every population has background "nodules". And if you give thyroids extra iodine (radioactive or not), or don't have enough iodine, you are going to affect the thyroid on a short time scale.
So nice try, but 0% rate is bullshit.
And if you bother reading the link, you'd find that the stupid belief that nodules == cancer is dropping.
1950's approximately 70% of thyroid nodules in children represented cancer, whereas currently that number is closer to 20%
And that is for nodules you can feel with your fingers (you know, large ones!), which highly correspond with cancers, not the "tiny ultrasound only visible nodule".

Re:...and It's red because...
TFA fails to explain a curious trait of deep-sea beasties like this. They're red because in very low light conditions, red appears black - good camouflage in an inky abyss. Red pigment is much easier for creatures to synthesize than black
Most cephalopods can change colour in an instant. It is used as a complicated and beautiful means of communication. Their bodies are covered in chromophores that are tightly integrated into their nervous system. It really is incredible, they will oscillate waves of color, light and dark across their bodies in complicated patterns. This most often occurs in mating, fighting, feeding and fleeing.
Knowing this almost makes me feel guilty when I enjoy grilled squid fillets (not deep fried rings). They are smart and beautiful animals, but dammit they are pretty tasty too!

True Story:
Octopuses have intrigued scientists for years, because they have both long- and short-term memory, they remember solutions to problems, and they can go on to solve the same or similar problems. They have been known to climb aboard fishing boats and open holds in search of crabs. They can figure out mazes, open jars, and break out of their aquariums in search of food.
This part of the linked article rang very true for me.
True story:
Octopus are underrated. Seriously. I used to have an (Octopus bimaculoides) as a pet (her name was Cephus, short for Cephalopod) and I was always amazed at the intelligence and problem solving abilities she exhibited. One day I was returning from working all night at the sleep lab followed by a day of class. I had a new bag of goldfish to feed her and placed them in the "goldfish tank" across the table from her 100gal aquarium. She always got excited at that and would hang on the side of her tank and look at the goldfish. At any rate, I got a couple hours of sleep and then ran back to work for another all night shift. Upon stumbling back home the next day, I was stunned to find no goldfish in the goldfish tank! I did not know if I was just seriously sleep deprived or what, but closer inspection revealed goldfish scales floating around in Cephus's tank........and a trail of dried salt water on the table top from her tank to the goldfish tank. She had opened the top of her tank, navigated across the table to the goldfish tank, helped herself to every last goldfish in the goldfish tank and then crawled back home, closing the top of her tank! All I could do was stare in dumbfounded amazement.
She also exhibited curiosity with new objects placed into her tank, exploring them extensively, and I must admit, it is most interesting in that unlike other aquatic non mammalians.....when you looked into an octopus eye, they look back at you. There is something absolutely intelligent behind those eyes.

Dictionary.reference.com is correct.
I spent five years working with malacologists on the largest molluscan collection in the western hemisphere. I have seen many dead octopi floating in alcohol, and I have written many lines of code that dealt with octopuses.
You'd be suprised how often the snail doctors get asked this question. And they always answer it the same way: "We use octopuses, and fishermen use octopi, but either is correct".
Nobody ever even tries to bring up any nonsense about octopeet, and rarely is octopodes brought up, because that is Greek for all eight-legged creatures (cf. arachnids) and not just octopuses.
See this article about octopus hurling in the on-line Cephalopod Database. -
Octopodes, of course

Re:Well, c'mon...While I don't know much about N.Korea in particular (besides that they aren't the nicest guys on the block), I am very sceptical that any of the allegations made can stick to them.
Good grief. No one is alleging anything. The North Koreans state that they have the bomb. If South Africa, Pakistan, and India could build the bomb, what makes you think that North Korea couldn't? And by the way, they are more than just "not the nicest" guys on the block.
They want to look scarier than they really are so they can blackmail others into giving them what they need (in this case energy, whether in petroleum from US or otherwise).
First rule of getting out of a hole: stop digging.
If you consider that we have an 'undeniable' proof that Iraq has chemical, biological and possibly nuclear weapons, and we haven't found squat there yet, I wouldn't be very convinced that allegations about Korea are anywhere close to truth at all.
There isn't any issue of allegations regarding Iraq. Iraq built chemical and biological weapons, and was building nuclear weapons. They used chemical weapons in the war against Iran. The UN inspectors found and destroyed some biological weapons. They disabled a nuclear program that was close to building a bomb. The real question is, did they find it all? When Saddam kicked out the inspectors 5 years ago, there were hundreds of tons of material unaccounted for. They had 4 years to hide it. Iraq developed binary chemical weapons, which means that the lethal chemicals are produced by mixing two other less dangerous chemicals. The UN found empty chemical warheads just prior to the war. (Empty chemical warhead, hundreds of tons of missing chemicals, binary chemical weapons technology..., four years to hide it... hmmmm.) Since you might be as ignorant about this topic as you admit about Korea, try visiting www.fas.org, and maybe doing a little research.
Give me a break! If 20 years ago we knew what computers would become now,..
What computers would become now? I don't know how to tell you this, but 20 years ago computers were just as important to our economy then as they are today. Security issues weren't discovered behind a tree last week. Y2K was being written about at least as far back as the mid '80s, and like most big problems, ignored and pushed off until the last minute.
You've gotta love our fellow

Re:Death?
Yes, but not in the way you think. We can use apoptosis to kill harmful cells, like cancer cells. This is a "natural purpose" of apoptosis, and drugs are under development to "encourage" cancer cells (and virally infected cells) to die by this mechanism.
The theory that apoptosis plays a central role in human aging is part-and-parcel of the "free radical" theory of aging, which I think is bullshit.
The basic idea is that reactive oxygen species - these are chemicals that want to take electrons away from biological molecules and can do in such a fashion that the biological molecule is damaged - damage your mitochondria in such a fashion that the mitochondria signal the cell to die. This definitely CAN happen - however, I don't believe that it actually does, or that any of the pathologies we observe in human aging actually depend on this pathway. Btw, I'm a bioinformatician (grad student); when I worked with my Dad, I studied oxidative stress - he still does but he does not think it plays a role in normal aging. Certain conditions - being a chain smoker, being on hemodialysis, whatever - may actually put enough of these reactive oxygen species into your system that this could happen, but I doubt it.
FYI: some people try to sell you antioxidant dietary supplements (or other treatments.) I cannot emphasise enough - these products are snake oil. Even if reactive oxygen species do play a significant role in aging (which I doubt,) taking spills to scavenge them or soak them up is utter malarky.
The opinion of someone with whom I disagree almost completely. More of the same - the summary is fairly accesible.
To sum up - I can't say conclusively that there is no aging-related process that depends on apoptosis, but I don't find the evidence at all convincing. The one that people are fond of at the moment, which is oxidative stress-come-apoptosis, is hogwash.
Aptoptosis serves two functions:
1) Developmental. Developmental Aptoptosis is necesarry to "carve out" your body. For example, when your fingers form, the tissue between what will become the fingers goes aptoptotic and dies. There is no real evidence that this is what happens when you get old.
2) Defensive. Cells which are pre-cancerous, or which have been infected with viruses, can become apoptotic. Certain conditions that some old people get - autoimmune disorders, for example - depend on apoptosis to do harm. However, this is not a part of normal aging.
P.S. Most scientists pronounce it "apo-tosis," the p is silent (like pterodactyl.) On the other hand, by this reasoning, helicopter (which comes from the same root as pterodactyl) would be "heli-coter", so say the p if you want. -
Re:Octopuses?I thought the plural was octopi.

Hmm...
It should be said proteins are formed by RNA, specifically by ribosomes and synthesised by the endoplasmic reticulum. I speculate how this drug works..perhaps by hindering operation of the protein organelles? Regardless, be sure to check out cell biology @ utmb under the protein section, if you're interested in how proteins function (this was missed in the article).
