Why oh why do I continully here stories about liquid nitrogen when liquid propane would do a much better job? Liquid nitrogen has a very poor heat capacitance then almost anything else that looks cool and makes alot of frozen water vapor clouds. My thought BFD. give me a real 6.0 processor that doesn't need liquid cooling and then i'll be impressed.
forget not a deep sleep mode for you laptop after you convert it into a semiautomous rover
Crap if they can't get it right what makes you think you can?
based on the DNA within
Although genetic mutations are the hallmark of cancers, mRNA, protein levels or even lipid levels would be a better target for these "mini-attack bots" since there is duplication in the genome.
sheesh, I was only making a vague reference to Robin Williams and South Park. Next time I'll spell it out. I really love Canada and would love to immigrate. I think the Canadians like to be picked on, at least the ones with a sense of humor ehh?
At least I avoided the whole first post sheengains by not making a big deal of my feat.
Bernoulli's principle still applies, in fact, water behaves alot like air, except that it's more dense. you have to have the right airfoil shape thought
This team at Virginia Tech, (I used to be on it) are the three time world champs for a human powered submarine. Check them out, lots of cool videos, and documentation.

Imagine never having to polish your shoes again, having glistening white teeth without visiting a dentist, or owning a mobile phone powered by a miniature battery. These are not just idle fantasies, but a reality where small things could make your wildest dreams come true.
A band of scientists believe they can push the boundaries of chemistry and physics to create a host of tiny particles that could revolutionise products we use every day. Welcome to the wonderful world of nanotechnology.
You may already be digesting and using nanoproducts without knowing it. Fizzy drinks and fruit juices get their rainbow of colours from tiny particles that dissolve in liquid and disappear without a trace.
Many vitamins are insoluble in water but can be added to food by making them into particles smaller than the eye can see. Cosmetics such as sunscreen are made of mini-particles that act as miniature solar soldiers, absorbing harmful ultra-violet light to protect your skin from the sun.
At a recent conference in Mannheim, Germany, scientists working at the chemical company BASF presented a huge range of products that could soon be out on supermarket shelves.
Nanotechnology has been heralded as one of the key technologies of the 21st century. By manipulating particles 50,000 times smaller than a human hair, materials can be merged into products or can create new properties.
Manufactured products are made from atoms. Their properties depend on how the atoms are arranged. What nanotechnology does is build things one atom at a time to create myriad novel molecular goods possessing amazing properties.
The magical trick is to manipulate the molecules and place them where they are needed to make the right structure. Nature has played an inspirational role in pushing this mini-world forward.
The leaf of an exotic flower inspired the creation of a spray that refuses to let dirt stick to shoes. The lotus flower from Asia has leaves with a strange arrangement of wax crystals on its surface that repel water. As this liquid rolls over leather, it takes any dust or dirt along for the ride, leaving your shoes spotless.
Harald Keller, a polymer scientist at BASF, has trapped this lotus effect in a can. Once you apply the spray, it dries into the leather and takes on an arrangement similar to the leaves.
"I believe that, with improvements, this spray should conceivably last a few years before having to be reapplied," says Keller. It could also be used on building materials, paper and textiles.
It is not only footwear that benefits from the wonders of the nanoworld. The effect that film stars get from teeth bleaching to blind us on-screen could soon be available in a humble tube of toothpaste.
"At the moment, every time you brush your teeth you damage the enamel. This latest idea is to rebuild the attacked enamel using nanoparticles incorporated in toothpaste that seals pores and restores the natural whiteness of the teeth," says Ralf Norenberg, from the performance chemical division at BASF.
Norenberg made tiny particles of hydroxyapatite, which has the same chemical structure as tooth enamel. He found that, when applied to teeth, it created a protective coating that did not allow dirt to invade. The key lies in the unique shape of the apatite particles.
This material forms a suspension of rod-shaped crystallites that ensures the teeth get all-over smooth cover and demonstrates flawless organisation, claims Norenberg. Other products already on the market are not as effective and use optical brightness, which "paints" your pearly whites, causing pimples to form that allow bacteria to settle and breed on the surface.
The miniature wonder-workers do not stop there. In a world driven by technology there is always a need to create and store information more efficiently. As mobiles and laptops get smaller, their source of power needs to do the same.
A revolutionary nanocube that can store hydrogen may solve this problem. These cubes, combining the features of plastic drink bottles and sun cream - terephthalic acid and zinc oxide - have a huge range of applications. Their high surface area and porous nature allows them to adsorb hydrogen and release the gas as energy when a rapid drop in pressure occurs.
As they are rechargeable, they could replace conventional batteries. Storing the gas in a container the size of a cigarette lighter would mean they could power small portable appliances for up to 10 hours.

MOUNT STROMLO AND SIDING SPRING OBSERVATORIES
Astronomer at work: Alex Rodgers, a Research Fellow and later a Director of the Observatories, at the 50-inch Great Melbourne Telescope in the mid-1960s.
Established in 1924, the Commonwealth Observatory at Mount Stromlo, on the outskirts of Canberra, antedated the University by many years. In 1950 the Commonwealth Astronomer, Richard van der Reit Woolley, was appointed an Honorary Professor attached to the Research School of Physical Sciences; but it was not until 1957 that Mount Stromlo formally became a part of the ANU.
As the lights of Canberra began to interfere with the astronomers' viewing, the University moved to establish an observatory at Siding Spring in the Warrumbungle Range, 660 kilometres due north of Mount Stromlo. ANU scientists and engineers helped design and construct the Anglo-Australian Telescope at Siding Spring, which was commissioned in 1974. An advanced technology 2.3 metre telescope was constructed during the 1980s.
Astronomers at Mount Stromlo and Siding Spring Observatories have made outstanding contributions to astronomy and astrophysics. Research in the 1950s provided the first clue that the Magellanic Clouds had evolved differently from our own galaxy, and so offered new insights into galactic evolution. In the 1990s ANU astronomers were able to show that about 90 per cent of disc galaxies (such as the Milky Way) take the form of `dark matter', the unseen matter in the galaxies' haloes.

Imagine you are a bacteria. Then ask yourself would you rather have 2 nucleotides or 4 nucleotides in which to code for proteins? your codon size would grow from 3 to 4. (with a loss of alot of reduncancy in the process) a 33 percent increase. now multiply your entire genome length by 33 percent. it's more efficent to store data in this way. if you were to conceptulize files as exons you would find that bacteria are very clever in their file storage. exons overlap, some portion of one is read backwards for another. don't think computers. think data storage. we aren't talking about electricity, we are talking about mother nature.
IAAB (I am a biochemist) This is an interesting concept from a computer science aspect. Imagine instead of 1 and 0's you now had 4 (A,T,G,C)(or more if you were creative) items to choose from. You could pack alot more data into a smaller string because you wouldn't be limited to a on/off state. Also, evolution/mutation takes a long time relatively, and the bacteria has a ton of different ways to correct for mutations. Also, information exchange could be passed by bacterial sex, through plasmids and the like.
