Improving on the hypersonic skyhook concept

A tidal stabilized tether is called a “skyhook” since it appears to be “hooked onto the sky”. They are also called “hypersonic tethers” because the tip nearest the earth travels about Mach-12 in typical designs. Longer tethers would travel more slowly. A grapple system attached to the tip of the tether can thus reach down …

Controlling the quantum world

Wired has an article about the activity in ultracold physics Ultracold atoms could enable precise non-GPS navigation by using measurements based on the Earth’s rotation. Very precise measurements of the strength of magnetic or gravitational fields can be used to find oil. This is only part of the revolution from measuring and controlling the quantum …

Silicon spintronics closer for cheap continuation of Moore’s law

From EEtimes, Naval Research Laboratory (NRL) scientists will next month describe a technique that would allow spintronics to be inserted into the standard silicon CMOS processes using ferromagnetic materials similar to those already used for magnetic random access memory. Our demonstration showed a 30 percent polarization of the injected electrons, which is not bad considering …

Accelerating Future on the Singularity and Transhumanist Technology

There are good articles at accelerating future. 1. Michael describes the confusion around the term the Singularity 2. He describes 10 top transhumanist technologies I would expand out item number 8 Gene therapy/RNA interference with synthetic biology and synthetic life and DNA nanotechnology. I also think quantum computers will be quite important Designer materials, new …

Breakthrough in understanding how embryonic stem cells function

Hat tip to KurzweilAI, the Toronto Star reports : a landmark discovery by researchers at McMaster University could radically alter the way scientists can use embryonic stem cells to grow replacement tissues and treat cancer. In a surprise revelation, a McMaster study found that human embryonic stem cells – “the great grandmothers” of all the …

Japan has made highly efficient ultraviolet light emitting semiconductor

Scientists at Japan’s National Institute of Advanced Industrial Science and Technology claim to have developed a new highly efficient ultraviolet light emitting semiconductor. The key is have they made it long lasting and stable ? If they have then the benefits of zinc over gallium LEDs would be realized. The benefits would be lower costs …

California population projected at 60 million in 2050

I had an article about USA and California’s population projected in Q1 of 2007. There is a new San francisco Chronicle article about California expected population. In the new report, state demographers used the latest county population estimates as a baseline to make assumptions about future migration patterns. The formulas they used accounted for undocumented …
