clipper's remarks: 3 ideas

Sperm-powered Nanobots

a brigade of medical nanobots, devices tiny enough to ride the flow of blood through the body's arteries to a problem area. The bots might arrive at a clot, for example, and then using an internal power system, obliterate the clot with a precisely targeted drug or therapy.

The same molecular power packs that fuel sperm in their journey through the uterus

Fusion On Tap

a form of nuclear energy so clean it generates no radioactive waste, so safe it can be located in the heart of a city, and so inexpensive it provides virtually unlimited power for the dirt-cheap price of $60 per kilowatt

Focus fusion is initiated when a pulse of electricity is discharged through a hydrogen-boron gas across two nesting cylindrical electrodes

built for just $300,000

A Two-Timing Universe

By adding a second dimension of time and a fourth dimension of space to Einstein’s standard space-time, Bars has come up with a new model providing “additional information

The final frontier got a bit closer today as Microsoft Corp. officially launched the public beta of its WorldWide Telescope, which is now available at http://www.worldwidetelescope.org.

“The WorldWide Telescope is a powerful tool for science and education that makes it possible for everyone to explore the universe,” said Bill Gates, chairman of Microsoft.

The application itself is a blend of software and Web 2.0 services

WorldWide Telescope stitches together terabytes of high-resolution images of celestial bodies and displays them in a way that relates to their actual position in the sky.

Users can choose which telescope they want to look through, including the Hubble Space Telescope, the Chandra X-Ray Observatory Center, the Spitzer Space Telescope or others.

They can view the universe through different wavelengths of light to reveal hidden structures in other parts of the galaxy.

clipper's remarks: sync-think, from brain trauma foundation, currently searching for a early detection combat test for brain injury on the battlefield-kinda cool

Reaction times are very often used to measure a person's alertness or level of attention.

The two tests on this site are an introduction to the field of reaction times and variability.

Individuals with fatigue, aging, attention deficit disorder (ADD) and traumatic brain injury (TBI) have problems maintaining attention, and they show more variability on reaction time tests than the normal population.

They found two planets that were close matches for Jupiter and Saturn orbiting a star about half the size of our Sun.

And he told a major meeting that astronomers were on the brink of finding many more of them.

The St Andrews researcher said this planetary system, and others like it, could host terrestrial planets like Earth. It was just a matter of time before such worlds were detected, he explained.

Astronomers discovered the largest diamond of all times in space. The weight of the precious stone reportedly makes up ten billion trillion trillion carats or five million trillion trillion pounds).

The white dwarf is not only radiant but also harmonious. It rings like a gigantic gong, undergoing constant pulsations.

Astronomers say that our Sun will die in five billion years and become a white dwarf too.
