Thursday, November 14, 2013; At Stanford University's Department of Physiology, Prof.
Stephen J. Smith has been working on a new technique for high resolution scanning of the mouse
brain called Array Tomography . He and his team have created a new YouTube video
called "Machinery of the Mind" (TRT = 2:18 min.) with Introductory MRI Data from
Brookhaven National Lab that was set to spooky music (by Catherine Rose Smith) intended
presumably to emulate the buzz of the EEG (from all the synapses firing, whether awake or
asleep). Remember, there are no sounds in outer space despite the swishing sound you hear when
a rocket ship blasts away from a space station in Sci-Fi movies, nor is there music going on in the
brain when synapses are firing. Nevertheless, you are led through multiple layers of cortex
panoramically from top to bottom. The complexity of what you're looking at is really
scary if you originally thought that the brain was a simple textbook model of neurons connected
like the computer simulations of neural networks from good old days (1990's). As you can now
see, there are thousands of dendrites connecting axons, not just a dozen or so. Click on the
photo above to watch

- Thursday, October 4, 2012; 4:00 PM PDT; Click for a short, extraordinary
video-clip of mitosis in a
Drosophila S2 cell expressing GFP-Ndc80, GFP-gamma tubulin, and mCherry alpha tubulin.
Time lapse photography images were recorded at 60 second intervals using a spinning disc
confocal microscope on a Nikon TE-200 stand with a 100x 1.4 NA Plan APO DIC objective lens
and recorded with a Hamamatsu Orca-ER CCD camera. Note the oscillations of the Mitotic
Spindle Apparatus at the end of Metaphase but before the rapid sister-chromatid separation
occurs in Anaphase. This requires both a forward and a reverse kinase protein infrastructure.
Why does Nature need such an expensive pulley system? Is it to ensure that all chromosomes are
connected to their own tubule before there is a "go" signal to start sister-chromatid separation?
One wonders why eukaryotic cells evolved so as to do this at all, and why it works so often
without pathological trisomies. A single non-synonymous mutation in one of the kinekore-
protein genes would be lethal, since they are on the critical path for all mitotic divisions.

by not removing her feeding tube on the grounds that she was in a potentially reversible
long-term coma and not in an irreversible Persistent Vegetative State (PVS)
(with no sign of a cortical EEG). (There is an intriguing intersection between this Chart and the
funding of a lawsuit opposing the implementation of California Prop. 71 on Stem Cells in the
Superior Court of Alameda County.) Three recent books on the topic of Ms. Schiavo are as

Here are the 27 elements that compose the human body taken from The Periodic Table
in order of descending body weight (our cosmic recipe derived from star dust) [1,2]. For interest,
elements that are toxic have been added in the next section.
Essential Elements:
Atom Percent by Weight Full Name
1. O 65.0 oxygen
2. C 18.5 carbon
3. H 9.5 hydrogen
4. N 3.3 nitrogen
5. Ca 1.5 calcium (in bone)
6. P 1.0 phosphorus (in phosphates)
7. K 0.4 potassium
8. S 0.3 sulfur
9. Cl 0.2 chlorine (in salt)
10. Na 0.2 sodium (in salt)
11. Mg 0.1 magnesium
12. I * iodine (in thyroxin T3, T4)
13. Fe * iron (in hemoglobin)
14. Zn * zinc (in carbonic anhydrase)
15. Co * cobalt (in Vitamin B12)
16. Mn * manganese (in SOD)
17. Cr * chromium (in picolinate)
18. B * boron
19. Ni * nickel
20. V * vanadium
21. Sn * tin
22. Si * silicon
23. Mo * molybdenum
24. Cu * copper
25. F * fluorine (fluoride placed in municipal water supplies to strengthen tooth enamel)
26. Li * lithium (contaminates some water wells in the form of lithium carbonate and is now used
for Rx: Bipolar Disorder)
27. Se * selenium (only at low doses; see Toxic Table)
________________________
* Only trace amounts (< 0.1 percent); some mineral elements are essential while the value of
others (or their dosages) in human nutrition has not been established. Conversely, too much of
some of these minerals - - like manganese, chromium, or selenium - - can also be toxic or even
fatal.
Toxic Elements:
Here are 42 toxic elementts and/or isotopes. Many toxic elements are fatal if inhaled or ingested,
but even a compound as simple as Carbon Monoxide (CO) [an odorless, colorless gas] becomes
fatal when inhaled inadvertently. Many heavy elements are toxic due to their weight. Many of
these have isotopes that are toxic due to their radioactivity...
Atom Full Name
1. Pu plutonium (the most toxic element known to man) [6]
2. U uranium [U 239 in pitchblend] (the next most toxic element known to man) [6]
3 . Ra radium (carcinogen; from [1910-1927] US Radium, Inc. of New Jersey sold paints
containing radium to help women manufacture watch dials that glowed in the dark. :-( )
4. Po polonium (once used in a political assassination in London by the Soviet KGB)
5. As arsenic (a favorite poison from the Renaissance but still used today as a rat poison)
6. Au gold
7. Ag silver
8. Pt platinum
9. Pb lead (neurotoxic in paints)
10. Al aluminum
11. W tungsten
12. Rn radon (as a gas commonly in the soil)
13. Hg mercury (neurotoxic; Alice in Wonderland's mad hatter was actually a problem in
London at one time)
14. Ga gallium
15. Ge germanium
16. Cd cadmium
17. Se selenium (toxic only at high doses)
18. Th thorium
19. Be beryllium
20. Tm thullium
21. Sb antimony
22. Rb rubidium
23. Br bromine
24. Sr strontium [strontium-90]
25. Ce cerium
26. Ba barium
27. Cs cesium (caesium)
28. Ti titanium (application in hip or knee replacement orthopedic surgery)
29. H-3 tritium [hydrogen-3]
30. Tc-99m technesium [medical isotope]
31. I-123 iodine-123 [medical isotope]
32. TI-201 thallium-201 [medical isotope]
33. Ru-106 ruthenium-106 [medical isotype]
34. Ir-192 iridium-192 [medical isotope]
35. Co-60 cobalt-60 [medical isotope]
36. Cs-137 caesium-137 [medical isotope]
37. Y-90 yttrium-90 [medical isotope]
38. Pd-106 palladium-106 [medical isotope]
39. Rb-82 rubidium-82 [medical isotope]
40. F-18 fluorine-18 [medical isotope]
41. Ga-67 gallium-67 [medical isotope]
42. Kr-81 krypton-81 [medical isotope]
Note: Plutonium and uranium are both heavy metals, and thus are toxic due to
chemical effects, but not more so than all other heavy metals. However, if we consider only
chemical effects, radon doesn't belong on the list, since it is an inert noble gas, and thus is
harmful only because it's radioactive. (Also, radium and polonium, which are mentioned, are
harmful mostly because of their radioactivity.) If it is meant to include the effect of radioactivity,
there are elements whose common isotopes are far worse than plutonium or uranium (in some
cases by several orders of magnitude). Some of these are also more radioactive than radium,
polonium, or radon, which in turn are more radioactive than plutonium and uranium. - - Donald
Gennery, Biostatistics, JPL; Pasadena, CA (August 7, 2013)
Compounds: Both fiber glass and asbestos insulation are highly toxic (and
complex) compounds when inhaled due to the physical dimensions of the fibers when
they get lodged in the lungs. Poisonous mushrooms, belladonna (deadly nightshade,
atropine), and extremely minute amounts of LSD when swallowed have caused many
deaths. But so has alcohol (wood alcohol [methanol] as well as pure ethanol, as in wine,
beer, and liquor) and nicotine (in tobacco). Even too much water can lead to water
intoxication. Castor beans (Ricin) and Anthrax, likewise. Poison gas (phosgene) was
used in chemical warfare heavily in WW-1.

The third most common atom in the human body, hydrogen, was created shortly after the time
of the "Big Bang" and was not synthesized and blown out in supernovas as so-called "star dust"
for the heavy elements. If there are question marks (?) in the Wikipedia Tables
referenced below [3-5], this indicates that nobody knows, not that Wikipedia doesn't know.

6. Plutonium is less toxic than arsenic in terms of being a metallic poison, so breathing
plutonium dust will not normally deliver a toxic dose, but of course it's not the metal that will do
most damage; it's the radiation. A large dose of a uranium salt will cause vomiting and diarrhea
but again it's not as dangerous as consuming arsenic. I assume breathing uranium dust would
again not deliver a fatal dose, but you never know with the lungs because there are some metals
which breathed-in cause chronic illnesses such as beryllium and manganese.
