UK gives go-ahead for human cloning

March 6, 2002

The British government has approved research on embryonic stem cells for developing new treatments for disease and for therapeutic cloning, involving the cloning of embryos up to 14 days old.

Silicon nanoparticles enable microscopic lasers

March 6, 2002

Researchers at the University of Illinois have demonstrated a method of producing fluorescent colored nanoparticles from silicon wafers. The new materials could yield microscopic lasers and put optical communications on chips.
By attaching biological materials to the nanoparticles, their location could be traced in the body by stimulating fluorescence with just two photons from infrared beams.

Researchers also hope to some day replace wires with optical interconnects and create… read more

When Will AI Get Down to Business?

March 6, 2002

AI has quietly become embedded in a wide variety of businesses, including medical labs, financial services, airports, online job banks, and construction companies.
Examples of current AI applications include:

  • Web avatars used for “relationship modeling” in customer service systems
  • Detection of credit and debit card fraud
  • Extraction of medical and occupational data from life insurance applications
  • Personalized, Internet-based TV listings based on

    Neural net programs diagnose colon tumors

    March 5, 2002

    Researchers at the University of Maryland Greenebaum Cancer Center in Baltimore have devised a new method to differentiate and diagnose several types of colon tumors, using artificial neural networks to analyze thousands of genes at one time.
    The program could ultimately help doctors to identify the cancers earlier and spare some patients from unnecessary, debilitating surgery, says Stephen J. Meltzer, M.D., professor of medicine at the University of Maryland School… read more

    Robo-Therapist Helps Ailing Limbs

    March 1, 2002

    InMotion2 is a robo-therapist that its inventors believe can help patients regain the use of limbs incapacitated by a stroke.
    The robot emulates the physical therapist’s movements by putting the patient’s affected limb through a range of repetitive exercises designed to rehabilitate damaged nerve pathways.

    The patient sits at a table with his lower arm and wrist in a brace attached to the arm of the robot. The patient… read more

    Glowing nanobots map microscopic surfaces

    March 1, 2002

    Molecular robots used to explore a surface’s terrain can produce maps of microscopic structures and devices with higher resolutions than those produced by conventional microscopes, research shows.
    University of Washington researchers modified microtubules by fixing kinesin molecules (which normally move materials around cells along microtubule pathways) on a surface, causing the microtubules to propel themselves randomly on the surface.

    By attaching a fluorescent dye to the microtubules, the… read more

    High-tech soldier envisioned

    February 24, 2002

    A high-tech soldier with 20 times the capability of today’s warrior by about 2010 is envisioned by the Army and a team from Oak Ridge National Laboratory.Concept design teams met last year, composed of futurists, systems engineers, biologists, military experts, human factors specialists, writers and others met late last year to propose a plan of attack to the Army for the “Objective Force Warrior.”

    Nano-based DNA detection

    February 24, 2002

    Microelectrodes and gold nanoparticle probes are being used to create lower-cost, faster and more accurate DNA detection.Northwestern University scientists used a synthetic sequence of DNA that models the anthrax lethal factor to test a technology that could displace polymerase chain reaction (PCR) and conventional fluorescence probes in clinical diagnostics and make point-of-care DNA testing possible in the doctor’s office and on the battlefield.

    A simple electrical signal indicates that… read more

    Antimatter atoms captured for the first time

    February 21, 2002

    Antimatter atoms have been captured for the first time by researchers at CERN, the European Laboratory for Particle Physics.
    The research team used powerful magnetic fields to trap antiprotons in CERN’s particle accelerator and then introduced a beam of antielectrons, or positrons, and used an electric field to slow them down and bring the two types of particles together.

    When they exposed the particle trap to an electric field,… read more

    Senate to debate ban on cloning

    February 21, 2002

    The Senate is preparing to debate the Human Cloning Prohibition Act of 2001 (S.790), which would ban all forms of human cloning as well as the importation of therapies developed from cloned human embryos.”Such a ban could be passed without much public comment, so if you have strong views on this, get them in immediately,” Eric Drexler and Chris Peterson suggest in the Feb. 2002 Foresight Senior Associate Letter. “See… read more

    Robot care bears for the elderly

    February 21, 2002

    Robot bears watch over elderly residents in the world’s first hi-tech retirement home in Osaka, Japan.
    The bears monitor patients’ response times to spoken questions and how long they spend performing various tasks, alerting staff where appropriate via a local area network.

    Upside of Downsizing Analog Chips

    February 21, 2002

    Impinj has found a way to make analog devices employing the same CMOS technology currently used for making digital chips and fine-tuning them after they are produced. The result is analog devices that can be scaled down to tiny sizes and work better than the current generation of analog chips.
    The “self-adaptive silicon” technology is modeled on how the human brain adjusts nerve cells; it can monitor… read more

    A.I. Reboots

    February 21, 2002

    The focus of artificial intelligence today is no longer on understanding and replicating human intelligence but the development of systems to augment human abilities.
    Promising applications of the “new A.I.” include:

  • CycSecure, a program to be released this year that combines a huge database on computer network vulnerabilities with assumptions about hacker activities to identify security flaws in a customer’s network.
  • The “Semantic Web,” a sophisticated

    Pill reminders from robot pets

    February 20, 2002

    In the future, the elderly could be reminded to take medication by a computerized pet. The Pill Pets are brightly coloured, cuddly toys made of silicon, with a computerised screen that gives instructions on taking medication,

    For the Pill Pets to survive, they have to be told their reminders to take medication are being acted on.

    Artificial Muscles Gain Strength

    February 20, 2002

    Researchers have developed materials with properties closer to human muscles than anything yet seen. They will be perfect for an anti-gravitational suit, as well as for therapeutic and commercial devices.
    The MIT team has recently launched Molecular Mechanisms in Cambridge, MA to develop the technology and expect to create a “superman suit” for the armed forces that could enable soldiers to run, jump and lift to a nearly superhuman degree.… read more
