When the light turns red , a huge laser wall projecting apparitions of crossing pedestrians spans across the crosswalk . The concept is designed to keep crossing pedestrians safe from any overzealous drivers who otherwise might have ran the red light.

London (CNN) -- A tiny nano-sized car which can propel itself forward in response to electrical pulses has been created by scientists in the Netherlands. The electric-powered vehicle, which is the size of a single molecule, has a chassis and four paddle-shaped wheels and is roughly one-billionth the size of a traditional hatchback car. Its maiden journey wasn't exactly epic -- six nanometers -- and its fuel-efficiency wasn't world-beating either, needing a jolt of 500 millivolts every half revolution of its wheels.

It’s here in concept and I simply love it! The Tanning Printer is a solar powered printer that doesn’t use cartridges. Instead it uses the process of sun-tanning the paper! You got that right sir…sun tan! It seems outlandish right now, but trust me the idea is worth exploring… the design is here, it looks neat and sleek; now let the engineers figure it out!

Cold fusion debate heats up after latest demo - CBS News
Italian physicist and inventor Andrea Rossi has conducted a public demonstration of his "cold fusion" machine, the E-Cat, at the University of Bologna, showing that a small amount of input energy drives an unexplained reaction between atoms of hydrogen and nickel that leads to a large outpouring of energy, more than 10 times what was put in. The first successful cold fusion experiment was reported two decades ago, but the process has forever been met with heavy skepticism. It's a seemingly impossible process in which two types of atoms, typically a light element and a heavier metal, seem to fuse together, releasing pure heat that can be converted into electricity. The process is an attractive energy solution for two reasons: Unlike in nuclear fission , the reaction doesn't give off dangerous radiation. Unlike the fusion processes that take place in the sun, cold fusion doesn't require extremely high temperatures.
One weird theory could make anti-gravity and faster-than-light travel possible
So we've had neutrinos that traveled faster than light — or at least, that result hasn't been invalidated yet. But how soon can we get spaceships that can travel to other star systems without traveling at faster-than-light velocities? The answer might lie in a relatively little-known theory. Heim Theory holds the possibility for all kinds of seemingly science fictional things, from special engines that can work using gravity to space craft that move faster than light to many different quantized dimensions. How could these scientific miracles be possible?October 18th, 2011 by: Shane McGlaun This is the most awesome, intense, realistic (and painful) video game simulator I have ever seen. It’s not a fancy driving or flight simulator; this is a simulator for FPS games. It looks like you could train real soldiers in this thing.

This is some pretty exciting news. It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology. Now it looks like the first usable breakthrough has been accomplished.

12 bizarre real-life places that are stranger than science fiction | Blastr
Science fiction is home to some fantastic societies, from Cloud City to Bartertown. But you doesn't have to leave reality for this—our own world has places so abnormal, they make alien societies seem ordinary. Off the coast of Japan lies a series of volcanic islands. Due to the air being full of sulphur, they were evacuated as recently as 2000. However, citizens moved back, despite having to wear gas masks for most of their day.
Scientists reconstruct images from our brains, plan to do the same for dreams (video) -- Engadget
This is your brain. And now this is your brain on YouTube . By using functional magnetic resonance imaging (fMRI) software, researchers at UC Berkeley created a visual representation of what our brains see when we watch a TV or movie. It works as such: scientists show subjects random clips and measure the corresponding cerebral activity. After the computer "learns" what vids evoke what brain activity, scientists feed 18 million seconds of random YouTube videos into the computer program where it reconstructs a movie representation of neural happenings based on the hundred clips most similar to what it sees. Although the method currently only works with images actually viewed, the future goal is to recreate what people see in their dreams and memories -- which could give doctors major insight to the minds of the mentally impaired, stroke victims or those with neurological disorders.Harvard researchers showcase new dynamic motions for the LittleDog robot Who says you can't teach robots new tricks?

There was big news on the neutrino front last week, when the Japanese T2K (Tokai to Kamioka) experiment announced the first evidence (PDF) of a rare form of neutrino oscillation, whereby muon neutrinos turn into electron neutrinos. And this, in turn, gives physicist a potential clue to a critical mystery in cosmology: why there is something in the universe, rather than nothing . It's a small signal, just shy of of "3-sigma," but statistically strong enough, given the rarity of the event, to be a genuine signal, not just background noise. The probability of this being real, and not simply due to chance, is around 99.3 percent. "People sometimes think that scientific discoveries are like light switches that click from 'off' to 'on,' but in reality it goes from 'maybe' to 'probably,' to 'almost certainly' as you get more data," Dave Wark of Imperial College London and a member of the UK contingent at T2K, said in the official press release.
