RE: Captain Kirk's Clone And The Eavesdropper

This relates to an enduring question I have, which is also somewhat related to longevity. If I were to create a younger duplicate of myself in order to live longer, which one would then be "me"? They would both think they were me, but which one actually would be? I know that I still would not want to die, even though there was another, younger "me" in existance. My dad makes the arguement, how about if you were to go to sleep, and then the copy is made, or a perfect software/hardware copy made, and the older one just never wakes up. IMO I would still be dead, there would just be a copy of me running around. I still don't want to die even with a copy running around. Now for the part that really gets me. If you were to replace each cell in my body with a mechanical duplicate that exactly replicates its function, only do it slowly, would I then perceive that I was no longer me? I think it's a more a matter of perception than existance in any particular place, or it may be that you would need time to integrate the new parts before getting more. If you just yank out the whole brain, maybe that wouldn't work. There is a book I read not too long ago that deals with this issue Tomorrow and Tomorrow. Hopefully we'll both live long enough to find out.
Imagine Captain Kirk being beamed back to the Starship Enterprise and two versions of the Star Trek hero arriving in the spacecraft's transporter room. It happened 40 years ago in an episode of the TV science fiction classic, and now scientists at the University of York and colleagues in Japan have managed something strikingly similar in the laboratory - though no starship commander was involved.

RE: Space-elevator tether climbs a mile high

A slim but superstrong cable reaches a mile into the sky, while robots scrabble up and down the line – one day, the cable will end in space

[Via New Scientist]

This is promising, only a few months after the contest, we're progressing very nicely. I think the goal will be reached well before 2018

RE: New technologies enhance quantum cryptography

A team of Los Alamos National Laboratory scientists, in collaboration with researchers from the in Boulder, Colo., and Albion College, in Albion, Mich., have achieved key distribution (QKD) at telecommunications industry wavelengths in a 50-kilometer (31 mile) optical fiber. The work could accelerate the development of QKD for secure communications in optical fibers at distances beyond current technological limits.

Nanolaser Device Detects Cancer in Single Cells

I'm not sure if this will make that much of a difference. I wonder how many single cells actually go on to develop into a tumor. I'm not sure if detecting every single cell that is cancerous is wirth it at this point, perhaps when we have cheap s in the blood that can easily make use of this to eliminate the offending cell this will help.
Using an ultrafast, nanoscale semiconductor , investigators at in New Mexico, have discovered a way of rapidly distinguishing between malignant and normal cells. Moreover, this new technique has the potential of detecting cancer at a very early stage, a development that could change profoundly the way cancer is diagnosed and treated.

Sonofusion Experiment Produces Results Without External Neutron Source

Hopefully this will lead to "cold" fusion that will actually generate electricty. At the moment it still uses a lot more than it generates
A team of researchers from , , and the has used sound waves to induce nuclear fusion without the need for an external neutron source, according to a paper in the Jan. 27 issue of Physical Review Letters.

self healing paint job

Scratches no match for Nissan's new car paint

This is pretty cool, even though it is just the paint job on a car. Think how much money this can save the consumer though!

Cloned food

Poll: People reluctant to buy cloned food

This just seems silly to me, how much difference could it make being cloned or not? With the possible exception that it might somehow cause something like a prion disease. If it's meat, you're cooking it anyway, denaturing almost every protein and enzyme that would be in it. Plant material is less worrisome anyway, I don't think there is a disease that we can catch from plants (maybe caused by them, but not catch from them)

New microscope allows scientists to track a functioning protein with atomic-level precision

New microscope allows scientists to track a functioning protein with atomic-level precision

This has allowed the researchers to watch RNAP to travel up the DNA strand and for the first time see exactly how transcription works. This currently has potential to affect the field of proteomics and protein folding study, and who knows what else down the line can be found for it.

Plastic computer chips

Plastic Diode Could Lead To Flexible, Low Power Computer Circuits, Memory

This could lead to some interesting things, I don't think the developers give their results enough credit. I think this could lead to ubiquitous computing, with truly personal computers, woven into our clothes, and even more of the products we use daily.

Space

SPACE.com -- Former X Prize Rivals Announce Partnership

This could lead to very good things, if they can get some contracts going, this would speed the commercialization of space, they would also give some competition to SpaceX, both which would be a very good thing.

Synthetic muscle

New Scientist Breaking News - Light could trigger super-fast synthetic muscles

Synthetic muscle based on the current polymers could be 100000 times faster than they currently are, if we used a different way of triggering them. Researchers suggest that the technical challenges put this a decade or more away, but that's probably based on linear thinking, so I'd say 5 maybe on this one.

Fusion power

Focus Fusion Reactor - a Plasma Focus Device plus Hydrogen-Boron Fuel

This promises to be a great thing if it ends with success. It would eventually eliminate our dependance on fossil fuels, once our infrastructure converted over. This could also give a push to the hydrogen car movement, with these generators to split the water, you wouldn't be dependant on fossil fuels for that.

Google Print

Vast cyberlibrary unveiled by Google (Update)


This has the possibilty of becoming something like a modern day , if only people would give it a chance. I don't see the problem with the way Google is implementing this. If you're not going to have an issue with a public library allowing people to borrow books, why would you have an issue with this? I see this as yet another symptom of the litigious society that we have become.

Light chips

New Scientist Silicon chip works on the speed of light - Breaking News

Seems like it was just two weeks ago when the possiblity of computers made of light was brought up. Oh wait, it was. IBM has made a prototype switching chip using photon waveguides which can slow down light, with the idea that such a device could synchronise data streams by slowing some streams, allowing others to catch up. However heating the waveguides takes a long time compared with the switching speed needed in an optical network. And the waveguides have to be carved with an accuracy of 1 nanometre.

Convergance

KurzweilAI.net

Biotechnology, which is known primarily by its medical and agricultural applications, is increasingly being focused on the building of new biological materials and machines in an astonishing diversity of structures, functions, and uses. The advent of nanotechnology has accelerated this trend.

And it is information technology that is pulling all this together. Information technology has been the catalyst behind the convergance off these technologies, allowing much greater collaboration, search, information dispersal, and far easier research.
