Quantum Dots made brighter by a 108 to 550 times factor

By placing quantum dots on a specially designed photonic crystal, researchers at the University of Illinois have demonstrated enhanced fluorescence intensity by a factor of up to 108. Potential applications include high-brightness light-emitting diodes, optical switches and personalized, high-sensitivity biosensors. A quantum dot is a tiny piece of semiconductor material 2 to 10 nanometers in …

Rocket powered mechanical arm, ten times power of commercial arms

We are getting closer to cyborgs that are as strong and as fast as people. The prototype rocket powered mechanical arm can lift (curl) about 20 to 25 pounds – three to four times more than current commercial arms – and can do so three to four times faster. “That means it has about 10 …

Personal Air vehicle, Dayjet air taxi and ecodriving coach

Nasa crowns a Personal Air Vehicle prize winner Pipistral Virus is a 50mpg two seater plane that costs $70,000. Dayjet, air taxi service, is nearing a soft launch Eclipse 500 By Aug 21, 2007, Dayjet will have 11 jets. They are close to launching the first per-seat, on-demand air-taxi operation. before DayJet can fly passengers, …

Predictions on Artificial General Intelligence

Bruce Klein crafted a poll to gain a better perspective on the time-frame for when we may see greater-than-human level AI. There are several interesting answers to the question. The question was interpreted in many ways. I interpreted the question to be when will there be artificial general intelligence which has capabilities that signicantly exceed …

Another nuclear plant for the USA and more nuclear power

Many people think that nuclear power is not being added in the USA or that it cannot be added in time to help with climate and pollution problems. That belief is not correct. The world has 320 nuclear reactors in the construction pipeline This is an increase of 80 reactors from January 2007 when 240 …

Discovery of first gene that specifically links calorie restriction to longevity

Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …

Wealthy consumption, airplanes and the environment

Future pundit brought up a concern about high consumption by a lot of rich people in the future causing environmental problems I examine more of the statistics around the current situation. Previously I looked at what the projected wealth situation might look like. Work is being done to reduce the environmental impact of planes. Molecular …

UK Proposal for sub-angstrom precision computer controlled actuators

Another proposed project from the UK Ideas factory to create reconfigurable computer controlled actuators with sub-nanometer to sub-angstrom precision. We propose a scheme to revolutionise the synthesis of nanodevices, nanomachines, and, ultimately, functional materials via the positional assembly of molecules and nanoscale building blocks. Computer-directed actuators will be used to drive (with sub-nanometre to sub-Angstrom …
