Toward a Urine Test for Corony Artery Disease

A new urine test that is about 80-92% accurate could allow for early detection of coronary artery disease. Coronary artery disease (CAD) is responsible for most of the 1.5 million heart attacks that occur in the United States each year. A cheap and simple test for biomarkers would allow for early detection and monitoring of …

Freitas and Merkle Champion the Diamondoid Path which Drexler Now Downplays

Eric Drexler, one of the primary originators of many of the concepts of molecular nanotechnology, has written an article which clarifies his position on diamond based molecular nanotechnology. Robert Freitas and Ralph Merkle and others in the Nanofactory Collaboration have written a response indicating why they have chosen the direct to diamondoid development path. Our …

Qimonda May have Carbon Based Memory Progress

Nikkei Electronics is reporting that Qimonda will be revealing research success with carbon based memory that could scale to 3-4 nanometer dimensions. Qimonda developed a technology to switch those allotropes by applying an electric current. Specifically, the technology can switch among CNT, conductive carbon such as graphite and insulating carbon like diamond. At this point, …

Superconductor at 212K

Joe Eck at superconductors.org continues his research with superconductors and reports signs of superconductivity over 212K by doping a recently-discovered 200K tin-copper-oxide superconductor with a small amound of indium. The improved formula becomes (Sn5In)Ba4Ca2Cu10Oy. Although the 212K phase forms as a very small volume fraction within the bulk, sharp resistive and diamagnetic transitions are clearly …

Tech Roundup: Robot population forecast, super lubricant

1. BAM, a “ceramic alloy”, is created by combining a metal alloy of boron, aluminium and magnesium (AlMgB14) with titanium boride (TiB2). It is the hardest material after diamond and cubic boron nitride. -BAM is much slipperier than Teflon, with a coefficient of friction of .02 compared to .05. Lubricated steel has a friction coefficient …

World and China Economies in 2009 and Energy and Infrastructure Going Forward

The Economist estimates China’s past and current growth. They also examine China $600 billion stimulus effort. Any analysis of China’s growth prospects is clouded by the widely held belief that the government smoothes its GDP numbers and always overstates growth during economic downturns. The chart plots China’s official growth rate against an alternative estimate calculated …

Heart Attack, Stroke and Cardiovascular Risk Can Be Halved even if you have Low Cholesterol

Statins can help lower heart attack risk by 50% even if you have low cholesterol but do have a high level of C-Reactive protein (6 million people in the United States fall into this category and 250,000 fewer cardiovascular events – strokes, heart attacks, could avoided over five years if those 6 million were given …
