GPS accuracy for a robotic neurosurgeon: The MiniAture Robot for Surgical Applications (MARS) is already FDA-approved for orthopedic and spinal surgery. Now, Israeli scientists have given it GPS accuracy for keyhole neurosurgery. This is a minimally invasive procedure used for tumor biopsies or deep brain stimulation, but you need to know exactly where you operate. So...; Tags: Keyhole Inc., Robot, Registration, GPS, Robots, Emerging Technologies, Roland Piquepaille; Blog posts 2007-10-08
Magnetic 'snakes' for storage devices?: According to a weekly digest from the American Physical Society (APS), physicists at Argonne National Laboratory (ANL) have found that under certain conditions, magnetic particles could form magnetic 'snakes' able to control fluids. According to the researchers, this 'magnetic self-assembly phenomena may be used to make the next generation of...; Tags: Storage Device, Argonne National Laboratory, Storage, Transportation, Storage Management, Hardware, Roland Piquepaille; Blog posts 2007-10-07
Chipping software for faster debugging: If you've spent some time doing software development, you know that debugging and testing consume more time than writing code, especially on large projects. And when your product is finally released and a user discovers a bug, it can be very difficult to isolate the cause of the bug. In...; Tags: Program, Software, Technique, Variant, ChipperJ, Productivity, Tools & Techniques, Management, Roland Piquepaille; Blog posts 2007-10-06
A plastic as solid as steel: A new composite plastic built layer by layer has been created by engineers at the University of Michigan. This plastic is as strong as steel.

Finding leaks in a spacecraft: With financial support from NASA, Iowa State University (ISU) engineers have developed a sensor to quickly find leaks in a spacecraft. This sensor locates an air leak by listening to the noise generated by the air rushing out of the leak and includes an array of 64 elements that detects...; Tags: Leak, Spacecraft, Iowa State University, NASA, Sensor, Roland Piquepaille; Blog posts 2007-10-03

Identifying fingerprints in seconds: Researchers at the University of Warwick, UK, say they have developed a technology to identify damaged fingerprints in just a few seconds. Their approach neglects surface marks and focuses on underlying patterns. The researchers claim that their technique is fast and 100% accurate -- at least it was on 500...; Tags: Researcher, Print, Technology, Social Security, Biometrics, Productivity, Authentication/Encryption, Identity Theft, Operational Accounting, Security, Government, Finance, Roland Piquepaille; Blog posts 2007-10-02
Printing with enzymes: Researchers at Duke University have developed a new printing technique using catalysts to create microdevices such as labs-on-a-chip. Their inkless printing technique uses enzymes from E. coli bacteria and has an accuracy of less than 2 nanometers. While they're are now using enzymes to stamp nanopatterns without ink, the research...; Tags: Stamp, DNA, Catalyst, Duke University, Printing, Biotechnology, Document Management, Enterprise Software, Software, Finance, Managerial Accounting, Roland Piquepaille; Blog posts 2007-10-01
Virtual robots fooled by visual illusions: Researchers at University College London (UCL) have written a computer program using neural networks which are duped by optical illusions the same way as we do. Their virtual robots, which were trained to 'see' like us, could help to understand why we fall for optical illusions. This might also be...; Tags: Brain, Robot, Illusion, Robots, Emerging Technologies, Roland Piquepaille; Blog posts 2007-09-30
Self-powered nanowires: Many research teams around the world are building nanodevices of some kind. But these very small devices need very small sources of power to be fully functional. Now, researchers at the University of Illinois at Urbana-Champaign (UIUC) have shown that a single nanowire can produce power by harvesting mechanical energy...; Tags: Researcher, Voltage, Yu, Voltage Generation, Team Management, Nanotechnology, Management, Emerging Technologies, Roland Piquepaille; Blog posts 2007-09-29
Software to double your cell phone memory: Compression algorithms are not really new, so I've looked cautiously at the work of U.S. computer scientists claiming that 'they have developed technology that doubles the usable memory on cell phones and other embedded systems without any changes to hardware or applications.' The CRAMES (Compressed RAM for Embedded Systems) technology...; Tags: Software, Algorithm, Application, Phone, Performance, Memory, Embedded System, Cell Phone, Engineering, Performance Management, Human Resources, Workforce Management, Roland Piquepaille; Blog posts 2007-09-28
Liquid drops defying gravity: Researchers at the University of Bristol, UK, have shown that droplets of liquid can travel uphill when placed on a vertically vibrating inclined plate. 'In fact, if the plate vibrates at the right rate, the droplets will always travel counter-intuitively up the incline.' This very interesting discovery will not change...; Tags: Plate, Droplet, Workforce Management, Web Site Development, Web Technology, Human Resources, Internet, Roland Piquepaille; Blog posts 2007-09-27
Ordinary CD players to monitor our health?: Many of us, at least in developed countries, have CD players rusting in our homes. So why not turning them into something useful? A very short note by the American Chemical Society (ACS) says that Spanish researchers have adapted this now venerable technology into home health monitoring systems. This means...; Tags: Monitor, CD, Disc, Health Care, CD-ROM Drive, Roland Piquepaille; Blog posts 2007-09-26
Filming nanotubes inside living animals: A team of researchers at Rice University has filmed carbon nanotubes inside living animals. They've used a custom-built microscope and a technique called near-infrared fluorescent imaging to detect DNA-sized nanotubes inside living fruit flies. But more importantly, they've compared a group of fruit fly larvae fed with a yeast paste...; Tags: Nanotube, Larva, Carbon Nanotube, Fruit Fly, Nanotechnology, Emerging Technologies, Roland Piquepaille; Blog posts 2007-09-25
