I dreamt that I had fever. And to get rid of it, I was using this
lotion on my body which made my sweat glands go hyperactive and
increased the blood circulation near my skin somehow. As a result, I
sweat a lot, and hence lost my body's excess heat (the fever). All
this made me feel much much better in just a few minutes. And that's
about it.
Ok then...see you all next time!
It has been about 2 months now that I have come here. Gave up my
glasses with my newly shaped cornea thanks to some flashy lasers. And
I have tried to lose some kilograms at the gym in vain. I lost one.
The membership ended last week. The next gym I see will be the one
back in Montreal. Till then, I eat, sleep and do nothing much more.
Card tricks have always fascinated me and I just have a few tricks in
my deck at the moment..but maybe with more practice..and unlikely
devotion I will be able to come up with some more.
My cell phone lives on as a beaten soldier...the camera won't work
despite the repair effort put behind it. I am really urged to buy a
camera for myself when I get back this time. Pictures and
videos..maybe a video blog will be born further down the lane. But
given that I am somewhat (VERY) lazy and short of time when semester's
on, it's unlikely that I will ever start one. But hey..I am a dreamer.
Talking about dreams, I have had a few very creative ones lately. In a
previoust post I talked about a dead nail (the white part) dissolving
creame/lotion which acted as an alternate to nail-clipping and also
why planes can fly inverted even though their wings are meant to
create upward lift when upright and downward lift when inverted.
So recently I dreamt of an amazing razer..which used a jet of water in
a horizontal line..which removed hair from the skin without damaging
the skin at all. It was pretty cool because the person using the razer
on me was also talking about how land-owners were organising game
shows to find which winning contestant gets to buy their land.
Next, there was this other dream where..*spending a lot of time trying
to remember what it was..and also chatting away on MSN* ok
nevermind..will leave that to another post. I forgot what it was..will
have to ask father about it. Ok so, he doesn't remember either. Will
ask someone else about it. Arghh..i hate how I can't remember these
things at times.
Food; I have been thinking about food a lot lately (yeah what's new
about that you ask? well I don't know to be honest). But really, I
have been thinking about what I can make this time around in my
montreal kitchen. Been talking to people about food, been eating dhaka
food and asking how this and that has been made and so on.Stir fries
to cakes to sushis to subs to seasame beef to beef sashimi with teffo
at Odaki (:F) - everything is on the to-do list. (so are you AJ...ahem
ahem). So lemon rice is a must try as well. it's a special recipe from
a special person! :D only problem is..i am yet to get the procedure
from the chef :P
OK MOVING ON. Internet here is real slow. Can't youtube or watch TV
shows online here. Which is le suck.
I think i am going to check out some more digital cameras
online..reviews and ratings..(yes i am getting bored of writing this
as well.)
Sigh. Catch you all later.

A tiny chemical "brain" which could one day act as a remote control
for swarms of nano-machines has been invented.
The molecular device - just two billionths of a metre across - was
able to control eight of the microscopic machines simultaneously in a
test.
Writing in Proceedings of the National Academy of Sciences, scientists
say it could also be used to boost the processing power of future
computers.
Many experts have high hopes for nano-machines in treating disease.
"If [in the future] you want to remotely operate on a tumour you might
want to send some molecular machines there," explained Dr Anirban
Bandyopadhyay of the International Center for Young Scientists,
Tsukuba, Japan.
"But you cannot just put them into the blood and [expect them] to go
to the right place."
Dr Bandyopadhyay believes his device may offer a solution. One day
they may be able to guide the nanobots through the body and control
their functions, he said.
"That kind of device simply did not exist; this is the first time we
have created a nano-brain," he told BBC News.
Computer brain
The machine is made from 17 molecules of the chemical duroquinone.
Each one is known as a "logic device".
They each resemble a ring with four protruding spokes that can be
independently rotated to represent four different states.
One duroquinone molecule sits at the centre of a ring formed by the
remaining 16. All are connected by chemical bonds, known as hydrogen
bonds.
The state of the control molecule at the centre is switched by a
scanning tunnelling microscope (STM).
These large machines are a standard part of the nanotechnologist's
tool kit, and allow the viewing and manipulation of atomic surfaces.
Using the STM, the researchers showed they could change the central
molecule's state and simultaneously switch the states of the
surrounding 16.
"We instruct only one molecule and it simultaneously and logically
instructs 16 others at a time," said Dr Bandyopadhyay.
The configuration allows four billion different possible combinations
of outcome.
The two nanometre diameter structure was inspired by the parallel
communication of glial cells inside a human brain, according to the
team.
Robot control
To test the control unit, the researchers simulated docking eight
existing nano-machines to the structure, creating a "nano-factory" or
a kind of "chemical swiss army knife".
The attached devices, created by other research groups, included the
"world's tiniest elevator", a molecular platform that can be raised or
lowered on command.
The device is about two and a half nanometres (billionths of a metre)
high, and the lift moves less than one nanometre up and down.
All eight machines simultaneously responded to a single instruction in
the simulation.
"We have clear cut evidence that we can control those machines," said
Dr Bandyopadhyay.
This "one-to-many" communication and the device's ability to act as a
central control unit also raises the possibility of using the device
in future computers, he said.
Machines built using devices such as this would be able to process 16
bits of information simultaneously.
Current silicon Central Processing Units (CPUs) can only carry out one
instruction at a time, albeit thousands of times per second.
The researchers say they have already built faster machines, capable
of 256 simultaneous operations, and have designed one capable of 1024.
However, according to Professor Andrew Adamatzky of the University of
the West England (UWE), making a workable computer would be very
difficult at the moment.
"As with other implementations of unconventional computers the
application is very limited, because they operate [it] using scanning
tunnel microscopy," he said.
But, he said, the work is promising.
"I am sure with time such molecular CPUs can be integrated in
molecular robots, so they will simply interact with other molecular
parts autonomously."
