    The future of the world's first full-scale nuclear reactor, called the B Reactor, remains uncertain in the face of the US Dept. of Energy's effort to clean up the radioactive and chemical contamination at Hanford. Established by the Manhattan Project during World War II, the B Reactor is part of the Hanford site, a 1500-square kilometer plutonium production complex in the state of Washington. A st...

    An increasing number of computer rooms all over the world are switching from conventional servers to blade servers because they offer huge improvements over conventional, rack-mounted units. The greatest benefit of blades is their flexibility, which allows them to be easily installed, managed and repaired compared to conventional servers. The promise of blades lies not so much in their hardware as... View full abstract»

    This paper discusses how offshoring software development projects from the US, particularly those involving software programming and information technology, can put intellectual property (IP) at risk. Without reliable institutions for IP enforcement, outsourcers must place their faith in prevention rather than cure. However, even the best safeguards can never guarantee invulnerability. The ideal s... View full abstract»

    Research continues to develop volumetric displays that render images in a 3D space rather than on a flat screen, focusing on two main technological approaches to displaying solid images electronically. The first approach is known as swept volume, which uses a high definition projector or an array of lasers to bounce images off a screen that rotates so fast that the human eye perceives only a 3D im...

    Generating electricity from wave power is an old idea that gained new life when the quest for alternative energy sources began in the 1970s. This paper describes how the 17-year-old, Aaron Goldin, found an elegant way to do the job with a buoy, a gyroscope, and a generator. Goldin invented the "autonomous gyroscopic ocean-wave-powered generator", cobbled together from parts scavenged from an old t... View full abstract»

    This paper discusses the DNA career of Michael Heller. Combining his interests in biochemistry and electronics, Heller got in on the ground floor of the biotechnology revolution and helped establish the technology behind DNA microarrays. These dime-sized devices are used to quickly analyze hundreds of DNA samples at a time, to detect genetic diseases and mutations. Also, Heller pushed the technolo... View full abstract»

    This paper address the question of whether venture capital funding has helped to promote or stunt the growth of technological innovation over the past decade. A study of 1,303 electronic high-tech initial public offerings for a 10-year period ending in 2002 showed that the level of innovation during the decade was surprisingly low. The results also did not correlate well with venture capital fundi... View full abstract»

  • Stealing celestial fire [artificial lightning]

    Publication Year: 2005

    By shining powerful laser pulses between two electrodes, a group of French and German scientists found that they can elicit a controllable form of lightning. Using pulses from the Teramobile laser, electrons are ripped from air molecules creating a plasma and the refractive index of the air is changed, a phenomenon called the Kerr effect. The effect focuses the light just enough to balance plasma-... View full abstract»

    Hewlett-Packard Co., is developing a nanometer-size switch that has the power to amplify a signal. This power is one of the great features of transistors because it allows a signal to pass through a circuit without petering out. The switch consists of a single molecular layer sandwiched between two metal wires. HP achieved the gain it needed by using the so-called molecular crossbar, made from two... View full abstract»
