  1. Isolating adult stem cells on 3D Human Cells Grown · · Score: 1

    One of the big problems with the use of adult stem cells has been the difficulty in obtaining them in large quantities. The Catalyst television show last week described a process that has been developed to efficiently do this. It involves tagging the stem cells using antibodies, and attaching magnetic beads to the antibodies. A magnet is then used to extract the stem cells. In the procedure being described, the stem cells are then injected directly into healthy tissue, with the hopes that they will take on the characteristics of the healthy tissue, and replace nearby diseased or dead tissue. I would expect that the cells can also be used to regrow 3D tissue structures.

    It's in Perth (or at least it was. It tends to get around.)

  3. Re: Everything that can be advertised... on No More Next Big Thing? · · Score: 1

    ... will be advertised.

    Sounds more like an IBM PR Effort.

    Call my cynical, but have you noticed how much of the content is "IBM has done this" and "IBM will do that"? This smells like an article from IBM's PR company. They have made a provocative statement to get people reading and discussing the article. But the true intent is to say how wonderful IBM is, and oh, by the way, they would be good to do business with because they are really good at "innovating", whatever that is. Write it up, hand it to a journalist, bake for 2 days and serve.

  4. New Inventors Cane Toad Trap on Toxic Toads Taking Over Australia · · Score: 1

    Last year, the Australian New Inventors show featured a cane toad trap, which used a light to attract insects, which in turn attracted cane toads, which would jump onto the top of the trap and fall through trap doors. The trap won a competition with over 100 entries, sponsored by the NT government.

  5. Re:Over Kill? on Robotic Hand Translates Speech into Sign Language · · Score: 1

    I agree. This is an example of something that is fun but impractical. I assume they did it because they could, and because it would pique the students' interest in robotics, which is a worthy goal. As a real-world application however, a text-to-speech unit would be cheaper, much more robust, much smaller and more portable, most likely faster, useful to a wider market, etc. etc. But it wouldn't look as cool.

  6. Too late, too late! on Apple Sued Over iTunes UI · · Score: 1

    The patent application was filed in Feb 1996. The software was demonstrated at COMDEX in 1995. My understanding is that once you have made the details of your "invention" public knowledge, you cannot then retrospectively apply for a patent on it. In a way, you become your own prior art.

    Can any lawers out there explain the law on this?

    I find it amazing that hardware is advancing WAY beyond software.

    Well, fortunately the software has had a bit of time to catch up. The Reuters article, whilst current, is describing news from over one year ago, if you RTOFA.

  9. Re:DHS + FTA on The Problem with DHS's Plan to 'Buy American' · · Score: 1
    I'm wondering how this would apply to free-trade agreements, like the recently signed one with Australia. Quoting from one of the DPF documents:

    GOVERNMENT PROCUREMENT CONTRACTS
    Changes to regulations open doors to specific sectors, such as the US$200 billion US Government procurement market. Until now, the 'Buy America Act' has restricted Australian companies from bidding for US government contracts or obtaining GSA listings. Australia has been added to the Designated Country list, eliminating the 6% price penalty and enabling US Federal agencies and 29 US States to procure directly from Australian companies.

    To me, that means that there should be a level playing field. If legislation like this can be introduced, and be legal under the FTA agreements, then that makes you wonder as to the validity or worth of such agreements. It would be ironic and disappointing if these agreements were to be entered into, only to be followed by a slew of legislation enabling exemptions.

  10. Re:Their 60 mile wind (faq) explanation. on Sanswire Demonstrates First Stratellite · · Score: 2, Informative

    Let's assume that the props have to turn at 2500 RPM at ground level for the airship to keep station. If everything falls off proportionally, then at 65 000 ft, the props would still have to turn at 2500 RPM to keep station in a wind of the same velocity. However, aerodynamic drag would be much reduced due to the decreased air density, and so the energy required to turn the props at 2500 RPM would be much less. I'm not sure of the degree to which drag would be reduced, and this also doesn't take into account things like the constant friction of the motor bearings. But this part of their claims sound feasible to me.

  11. Re:rediculous on Ohio Wants eBayers to Post $50k Bond · · Score: 1
    I disagree with you. I accept the definition of auctioneer. But agent also needs definition. According to Websters, an agent is (amongst other things)

    "a person or entity (as an employee or independent contractor) authorized to act on behalf of and under the control of another in dealing with third parties"

    This indicates to me that eBay is the agent, and therefore the auctioneer, as they are the ones conducting the auction. Think of it this way - if you get Sothebys to sell something for you, it does not make you an auctioneer.

  12. 0.1 Angstroms per bit? Rubbish! on Microwires Can Replace The DVD-ROM · · Score: 2, Informative

    This article is full of crap. An angstrom is 10^-10 metres, and corresponds to the diameter of a hydrogen atom. In order to linearly store 10 gigabits (let's assume that the author intended to use "bits" rather than "bytes") in a distance of 0.1 metres, each bit would have to be 10^-11 metres long, which corresponds to a length of 0.1 angstroms. If the author mistook "giga" for "mega", and intended that the wire could store 10 megabits, then that would mean that each magnetic cell would be 10^-8 metres long - 100 angstroms or 10 nanometres. Storing a magnetic bit in such a short distance would be an impressive feat.

  13. Re:Cost savings on Internet-By-Airship Scheduled For Trial Next Month · · Score: 1

    If the blimps are above major metropolitan areas, then I would expect that most aircraft in the vicinity will be landing or taking off, and will need to be at much lower altitudes. These blimps have a very broad coverage, and so should be easily positioned outside of air corridors.

  14. Re:Why? on Delphi Renaissance · · Score: 1

    For example - you can get a pointer when you need to, but you don't have to drown yourself with them all the time

    Actually, with Delphi, any object that inherits from TObject (effectively all of them) must be created dynamically, and therefore pointers are required.

  15. Re:Prisoners photos? on Digital Cameras Change War Photo-Journalism · · Score: 1

    I think that we should expect the media to respect the dignity of the victims. Releasing the photos undoctored would be perpetuating the abuse against them. There is no way that the originals should be released, any more than photos or video of a sexual assault should be released to the public.

  17. Re:Not just that on Lindows' Heavy Hand Leads to Summit Dropouts · · Score: 5, Insightful

    This isn't just alienating developers. It's alienating the whole Linux community, including users, OSS contributors, commercial entities. These people and organisations are working in a cooperative way to achieve (at this time anyhow) related goals. Backing Linux for many organisations, especially commercial ones, can be considered risky. Linux is far less accepted on the desktop, and it is likely that within organisations that are supporting linux, there are strong camps that are opposing or only luke-warm towards it. This action by Lindows is going to give ammunition to the anti-Linux factions, and specifically from Lindows' point of view, destroy trust that is so important to strategic relationships.
