A far more accurate blood test for prostate cancer has been created The American Cancer Society projects that in 2007 there will be 219,000 new cases and 27,000 deaths. Yet detecting the disease early has always been problematic. The new tests accuracy: about 3 percent of the time, when the test was positive, there was …
From physorg, barium titanate (BaTiO3) nanoparticles in a polymer matrix could allow fabrication of improved capacitors able to store twice as much energy as existing devices. The improved capacitors could be used in consumer devices such as cellular telephones – and in defense applications requiring both high energy storage and rapid current discharge. MIT researchers …

This achievement has been described as “amazing” and “the biggest breakthrough in energy generation in decades”. It seems to indicate that no scientific hurdle stands in the way of nuclear fusion. Just 5-7 years of engineering and configuring about 60 next generation linear transformer drivers. Then refining the system for commercial use starting in 20 …
The Brookhaven group uses magnetism to manipulate spin in graphene, a material consisting of flat sheets of carbon atoms arranged in a hexagonal pattern. They’ve proposed ways to make materials consisting of layers of graphene mated to magnetic and nonmagnetic layers. These “graphene-magnet multilayers” (GMMs) are expected to retain their properties at room temperature, an …
UC researchers (in conjunction with First Nano, a division of CVD Equipment Corporation of Ronkonkoma, New York) have produced extremely long CNT arrays (18 mm) on their EasyTube System using a Chemical Vapor Deposition (CVD) process. “First, we were able to grow the arrays up to 18 mm,” he says, ticking off the achievements. “Second, …
The United Nations Food and Agriculture Organisation (FAO) has also recently published a report which provides more detail on global trends that reinforce the importance of developing aquaculture. In 2004, capture fisheries and aquaculture supplied the world with about 106 million tonnes of food fish, providing the highest apparent per capita supply on record. Of …
From Centauri Dreams, a historic discovery has been made of a potentially habitable earth-like planet around the star Gliese 581 (20.5 light years from us). The planet is about five times Earth mass, one whose radius is only 1.5 times that of our own world. Brian Wangwww.nextbigfuture.com
Al fin added good information on superconducting motors Note: Al fin has an excellent website with excellent coverage and analysis of future technology. Motors over 1,000 hp utilize approximately 25 percent of all electric power generated in the United States. I had reported yesterday that Korea should have commercial superconducting motors by 2010-2011 Here is …
Stanford researchers have shown that a human evolutionary ancestor, the sea squirt, can correct abnormalities over a series of generations, suggesting that a similar regenerative process might be possible in people. Missing limbs, scarred hearts, broken spines, and wounded muscles always try to repair themselves, but often the result is invalidism or disease. Even some …
UPDATE: Engineer-Poet analyzes the H2CAR proposal and shows why it is a misleading diversion from real solutions Proposed process One of the possible configurations of the proposed H2CAR process. Some images courtesy of Department of Energy/National Renewable Energy Laboratory. Clearly it would be best if coal was not used but biomass only. Scientists have demonstrated …
