"Researchers are using DNA to develop truly miniscule
computers that could someday surpass today's most powerful
supercomputers.
As fantastic as that sounds, scientists have already used
computers made of DNA molecules to solve simple problems.
Now comes word that University of Southern California
professor Leonard Adleman, who first conceived of DNA
computers eight years ago, has used DNA to solve a problem
with 1 million possible answers!
Whereas
today's most complex computers use figures and formulas, a
DNA computer's input, output, and software is made up of
molecules that store and process encoded information in
living organisms. And, unlike conventional computers, says
Ravinderjit Braich, a postdoctoral student at the USC
Laboratory for Molecular Science, a DNA computer can try
millions of solutions simultaneously. Conventional computers
dodder along one answer at a time.
Then
there's the DNA computer's footprint, if you will. Adleman
says, "DNA has such a high information density that you can
record the entire Library of Congress and encode it into DNA
that weighs less than 1 gram." - Larry Greenemeier"

Investigating Nano.
Supporting our growing number of discussions on "things
nano" (such as at
http://www.theharrowgroup.com/articles/20020401/20020401.htm#_Toc5165660),
reader Kimberly Allen who earned her PhD on "Buckyballs,"
the precursors to carbon nanotubes, points us to what she
considers "the authoritative site on nanotube science."
It's the work of Professor David Tomanek at Michigan State,
and the site carries a vast number of links to the world of
the very tiny -
http://www.pa.msu.edu/cmp/csc/nanotube.html .
I believe that keeping up on ever-faster changing and
evolving technologies such as nanotechnology is vitally
important to our individual successes, and to the successes
of our businesses. Here, reader Roger Williams offers
his perspective on the criticality of "looking ahead at
change."
"Change will always happen.
The rate of change, the second derivative, makes it more
difficult to judge just how that change might affect my own
decisions. The time between needed decisions, if you will,
has changed markedly, and in order to make rational
decisions about change, I want a view that reaches farther
into the future.
The Harrow Report ... helps
me get that longer-range view. It is not to say that your
reports necessarily have to be true to the last syllable, it
is the drift that is important. Informed prognostication is
valuable; it raises the chances that you are a) right and b)
have a reasonable and useful comment. And that in
itself becomes useful.
Thanks very much for the work
you do."
Dust In The Wind.
To Kimberly's point, "Dust in the Wind" is a phrase with
some romantic cachet, ranging from the hauntingly beautiful
song by that name from Kansas (http://hurl.content.loudeye.com/scripts/hurlPNM.exe?
clipid=007503901020006550&cid=600100 and
http://members.tripod.com/kansasfreak/dustwind.mid),
to NASA's Stardust probe that is collecting samples of the
dust wafting in the interstellar wind that originates in the
hearts of stars (http://science.nasa.gov/headlines/
y2000/ast24apr_1.htm).
But if work being conducted at the University of
California Berkeley and in other labs comes to fruition, the
"dust in OUR wind" won't be stardust -- it will be made up
of cubic-millimeter sized computer dust motes containing
power supplies, processors, sensors, and laser and
radio-based networking capabilities! These dust motes
will create vast interconnected "computers" that sip energy
at the infinitesimally small rate of picoJoules per bit.
(Yes, these days even the term "nano" isn't small enough --
"pico" (10E-12) is three orders of magnitude smaller than
"nano!" (10E-9))
Brought to our attention by reader Victor Panlilio, the
April 5 EETimes (http://www.eet.com/story/OEG20020405S0015)
describes how such "smart dust" could be scattered over a
battlefield by a high-flying unmanned aircraft, or mixed
into house paint, or even "...swallowed with your
breakfast cereal for health monitoring."

This work is still in the "macro" test bed stage, but it holds fascinating
potential for "changing the rules." (Additional insights are
available in the April 9 ZDNet.com article
"Computing With A Pinch of
Sand" at
http://zdnet.com.com/2100-1103-879388.html.)
Overall,
according to Yury Gogotsi at Drexel University (http://www.philly.com/mld/philly/business/technology/2975921.htm),
"Nanotechnology allows you to do things
that are impossible in the macroscopic world. Among the expected
breakthroughs are order-of-magnitude increases in computer speed, enormous
advances in health science, and the ability to create 'designer' materials
[by] assembling atoms and molecules."
And, of course, by assembling Smart Dust.
Consider this opportunity -- if Smart Dust DOES become prevalent, there
might be an emerging market for personal vacuum systems, and for
exceptionally good air filtration systems for our homes and offices, just
to keep the dust, and its intrusive oversight, at bay!
Hummm. Perhaps if all this does come to pass, we might find the
smart dust getting in our eyes! Then, er, I guess I'd have to change
my message to -- "DO Blink!"...

Today's common read-only DVDs hold a respectable 17 gigabytes of data,
while read/write DVDs typically have a capacity of about 4.7 gigabytes --
even that lower figure would seem to be plenty of storage. But as we
increasingly want to store large databases, video files and more, a "mere"
4.7 gigabytes begins to feel surprisingly like its smaller 640 megabyte CD
cousin -- not nearly big enough. So what's a budding digital packrat
to do?
Brought to our attention by reader Tom Arav, we might be looking at
storing data in far more dense "holograms," rather sooner than expected.
"InPhase Technologies," a Lucent spin-off, has now demonstrated its
"Tapestry" write-once holographic video recorder, which can initially
store 100 gigabytes, a tenth of a terabyte, on each removable disk!
Now that sounds huge, but as is so often the case, our appetites for
storage seem to grow exponentially. While 100 gigabytes can store
"20 compressed feature films [in standard video format] on one disk"
(http://www.inphase-technologies.com/news/demotapestry.html),
if we move to High Definition video that "huge" 100 gigabytes will store
only 30 minutes of uncompressed HDTV video! Again, we need more
storage. Happily, InPhase expects its technology to scale to
"terabytes of storage on a single disk."
How is this storage magic performed? Like many a good magic trick,
it's, um, done with mirrors (or more correctly, prisms). Instead of
simply recording patterns of ones and zeros on a disk as both CDs and DVDs
do, Tapestry records a complex hologram of an entire "page" of data in
each spot, thereby dramatically increasing the amount of data stored.
And then by varying the angle or wavelength of the hologram's "reference
beam," MANY of those data pages can be recorded (multiplexed) in
the SAME spot! (Like I said, it's seemingly like magic, as are so
many of today's technologies...)
This system has another very interesting feature: because it's not
reading a data stream of ones and zeros directly off of the disk, but
instead it's reading "pages" containing MANY bits with each "read,"
each of those bits on a page is instantly available "in parallel."
Which raises the effective data transfer rate to "10s to 100's of
megabytes/second."
There's a lot more to understanding this implementation of holographic
data storage, such as the specialized media that had to be created, and
insights are available at
http://www.inphase-technologies.com/ . Just click on the
phrase "Learn more on our technology tour" at the bottom of the
block labeled "Holographic Technology."
By the way, don't expect storage to stop even at the terabytes size that
InPhase plans to provide. I remember when the 650 megabyte CD-ROM
first came out, and many people said that "this would be enough storage
forever." Some technical publications began storing all their back
issues, and related software, on one disk, simply adding the newest issue
onto each cumulative monthly CD. But I recall that in less than two
years, the addition of newer, larger, more graphics-intensive content had
them filling each month's CD with completely new content. Which is
how I expect the evolution of our storage needs to continue.
Don't Blink!

The Leading Edges -- One way to track the leading
edge of today's and tomorrow's technology trends is to note the survey
questions being directed at the developers who are honing those edges.
Reader C.W. Holeman II lists a few of the choices recently posed to
hardware and software developers by IntelliQuest, as they attempt to find
out which of these "leading edges" are being pursued:
-
Nanotechnology (software for micro chips and devices)
-
Biotechnology (software for data management of life
sciences)
-
Human-Computer Interaction (applications for interactive
computing systems)
-
Energy Sources (power supply for technologies)
-
Sensors (environmental sensors that interact with software
for monitoring activity)
-
Voice technology (Voice over IP, VoiceXML)
-
Autonomic computers (having computers heal themselves)
-
Grid computing (high end clustering)
-
Embedded systems (systems that are integrated)
-
Locational technologies (integrating with GPS)
Gee -- sounds like many of the foci that we
explore right here in The Harrow Technology Report!
Hopefully, we'll learn the results when the
survey is completed.

Repurposing -- We're pretty familiar with clear
spinning disks -- CDs and DVDs. They provide a wonderful medium for
consistently perfect reproductions of music, movies, and the like.
But if a new idea from BTI, brought to out attention by reader Don Lyle,
makes it into the marketplace, then a variant of these plastic disks might
soon be saving our lives!
According to an article in Tape-Disk Business (http://www.tapediscbusiness.com/0601/0601tdb5.htm),
Burstein Technologies Inc. (BTI) has demonstrated that by etching and
boring tiny microfluidic channels in the disk and embedding various
chemicals along some of those paths, a disk and a modified disk player can
perform instant diagnostic blood tests!
A drop of blood is placed near the center of the disk When the
"player" spins the disk, centrifugal force first separates the whole blood
from the plasma, and then forces the blood and plasma through various
on-disk chemical reactions and tests. The (specialized) CD-player's
laser then reads the results of the various tests.
BTI figures that they can incorporate 80% of existing clinical blood tests
into their CD laboratories, replacing $150,000+ laboratory analysis
systems with a $1,000 "Labtop" machines that could easily be used in
doctors' offices, or in tents, to provide inexpensive and immediate test
results.
Talk about "thinking out of the box!" What a fascinating
"repurposing" of mostly existing technologies, pushed in new directions by
some very innovative thinkers. It's also a VERY good example of how
previous disparate fields -- computers, entertainment, and medical
technology in this case -- are Converging! And there's room for a
LOT more.
Now if only they can get rid of the "stick" for that drop of blood...

Tag, Your Egg Is "It!" -- It's "it," that is, if reader Jeff
Daly's notion of embedded ID tags and the life cycle of certain food
products come to pass:
"I recall you covered the issue of
"chipping" people and pets with imbedded identification chips
(http://www.compaq.com/rcfoc/20000110.html#_Toc471710920),
and I'd like to revisit that issue.
An extreme example of one use of combining
several technologies you have covered is in quality control of food
production. Imagine, if you will, a chicken with an imbedded ID
chip. As it lays an egg, a sensor in the nest or cage identifies the
chicken and relays the information to a database, while a specialized ink
jet printer sprays an invisible (to the naked eye) barcode-type marking
onto the egg.
With specialized readers the egg can be
tracked throughout the marketing process! If, through
marketing studies, that egg gets high marks for taste, size, shape &
color, then the parentage that produced the egg can be identified.
That way, more flocks with those traits can be bred, improving the quality
of the product.
Conversely, if the egg is objectionable in
any way, those parent flocks can be phased out of production. In the
end, overall quality can be improved. Imagine applying similar techniques
to other forms of livestock, like pigs and cattle.
Hmmmm Although labor intensive
variations of this are already being done, it is just a matter of time
before the industry starts using the more innovative tools of technology.
I continue to devour every issue and
share/remind others of the useful tidbits of info found in it."
Thanks Jeff. And interestingly, the idea of tagging things is now
moving into the automotive world. According to a March 21 AP story
from thewmurchannel.com (the link to that
story is no longer active), Ford is planning to get its tire
suppliers, General and Continental Tire, to vulcanize wireless (RFID) tags
right into the tire's rubber! These permanent information caches
will detail where the tire was made, and the Vehicle Identification Number
of the car they're put on. Later, when the car is sold, the owner's
name will be added to the data stored within the tire itself.
These, I feel sure, are just two of the MANY new uses that we'll
find for the extraordinary technological bits and pieces that we keep
developing. And remember -- it’s the "unintended consequences" of a
development, or the serendipity between several of them, that often turns
an industry on its ear!
So again, "Don't Blink!"

But -- I just hope that they don't tag ME, considering that the
U.S. Food & Drug Administration has just ruled that an implantable
grain-of-rice-sized ID chip called the VeriChip from Applied Digital
Solutions,

is not a "regulated device," and so it can hit the market immediately
(http://wired.com/news/technology/0,1282,51575,00.html).

Finally, this sure looks like a tangle of that
favorite pasta, but this photomicrograph, brought to our attention by
reader Michael Engle, depicts carbon nanotubes produced by Prof. Yoichi
Hirose at Japan's Tokai University.
(Originally at
http://www3.yomiuri.co.jp/newse/20020404wo71.htm , but the link had
gone dead at press time.)
This wouldn't be of particular note, except that according to The Daily
Yomiuri, these nanotubes were made by a new process that combines a
heating element, a nickel target, and a little of this and that in a glass
bottle to produce carbon nanotubes far more inexpensively than current
techniques.
Oh -- and what was put into the glass bottle with those other elements?
Ninety-six proof vodka, and fifty-four proof whisky!
I wonder what a good single-malt might produce...
