Molecular map for aging created for Mice

Previous studies have studied gene expression changes during aging in just one tissue. The new work stands out because it is much larger and more complete, including aging data for 16 different tissues and containing over 5.5 million expression measurements. One noteworthy result is that some tissues (such as the thymus, eyes and lung) show …

Making cheaper, stronger and better carbon nanotubes without metal catalysts

NASA Goddard Space Flight Center has made a major step forward in reducing the cost of manufacturing single-walled carbon nanotubes (SWCNTs). Most manufacturing methods, which use a metal catalyst to form the tubes, have several drawbacks that have impeded development of SWCNTs’ numerous applications. NASA researchers have discovered a simple, safe, and inexpensive method to …

More on safer and more effective muscle enhancement

Two new classes of experimental drugs shown to have powerful muscle-building capabilities–selective androgen receptor modulators (SARMs) and myostatin inhibitors–have been added to the World Anti-Doping Agency’s (WADA) list of prohibited substances for 2008. I had discussed the myostatin inhibitor drug I believe that there is nothing wrong with safe muscle enhancement. Unlike steroids it will …

Glass fiber and Aluminum hybrid could save maintenance costs and reduce aircraft weight

The U.S. aluminum giant Alcoa, materials-technology company GTM Advanced Structures and scientists at Delft University of Technology in the Netherlands have patented a fiber metal laminate (FML) called CentrAl reinforced aluminum, or CentrAl, for use in aircraft manufacture. CentrAl provides some 25 percent more tensile strength than high-strength aluminum alloys, is extremely resistant to metal …

Suggestions for optimizing IQ test performance

Suggestions on how to optimize performance on an IQ test Let the “experts” argue about whether you can boost IQ or not, in any absolute sense. If you slept well, exercised, then sat up straight and breathed deeply as you took the test, don’t you think you would score a few points higher on an …

Quantum computing photon qubit communication advances

Two major steps toward putting quantum computers into real practice — sending a photon signal on demand from a qubit onto wires and transmitting the signal to a second, distant qubit — have been brought about by a team of scientists at Yale. They report that superconducting qubits, or artificial atoms, have been able to …

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 …

Phase change ovonic memory 2012 market share

Phase change memories (perfect RAM) are forecast to capture 5.5 percent of the NOR flash market by 2012. I have covered phase change ovonic memory before. It is 500 times faster than regular Flash memory Trapped charge memories increasing from less than 1 percent now to 30 percent of the NAND flash market in 2012. …

Self assembled Peptides for medicine: more SENS 3 abstracts

Using the mammalian visual system as a model, we showed that a designed self-assembling peptide nanofiber scaffold created a permissive environment not only for axons to regenerate through the site of an acute injury, but also to knit the brain tissue together, demonstrated by the return of lost vision. Bleeding can be stopped in less …
