A laser pointer, a dirty drop of water, and a wall, make an awesome projection Someone decided to shine a laser through a drop of dirty water and project the results on the wall This simple technique made an amazing projection of living beings in the drop of water The cat sure enjoyed it! [quote]After witnessing the image of a mosquito in a laser beam outside, I decided to investigate the phenomenon further I started by locating scuzzy water Ponds lacking, I decided to take water out of
Drinking water before your meal will help you lose weight Scientists confirmed that just two 8-ounce glasses of water, taken before meals, will enable people to shed weight [quote] We are presenting results of the first randomized controlled intervention trial demonstrating that increased water consumption is an effective weight loss strategy
We found in earlier studies that middle aged and older people who drank two cups of water right before eating a meal ate between 75 and 90 fewer ca
Japanese researchers have developed a robotic wheelchair that automatically follows a human companion
The wheelchair employs a distance sensor that tracks the position of a companion person, keeping the wheelchair always at the person's left
It also tracks the position of the companion's shoulders, anticipating where that person is moving next Even if the companion stands in one place and simply rotates, the chair will circle around to remain abreast of the companion

The most powerful lasers now being built, such as the forthcoming Extreme Light Infrastructure ELI project underway in Europe, may approach the physical ceiling of laser intensity -- they may turn out to be the most powerful lasers that ever can be built
That finite limit on how intense a laser can get is hypothesized to exist because, at sufficiently high energies, matter can be created out of light
When a high-powered laser fires, causing photons to impact electrons at a tremendous
Instead of having a video game that is all virtual, how about having it attached to an actual track with a real remote control car with a video camera on it Its a great idea except there has to be a human constantly on the job righting the car when it crashes Still with cardboard, and a huge semi ruined building you can have a lot of fun

This video shows all air traffic as small yellow points around the world over a 24 hour period Interesting how the traffic dropped during teh evening, especially in Europe when it almost totally disappeared

Here is another video this time of air traffic over Europe for 24 hours look at the nice tidy lines they all follow After 1 minute you see it 3D showing the altitude of the planes as well
The kind of drowning you see on TV—think thrashy, screamy—doesn't have much in common with what real drowning looks like, because of something called the Instinctive Drowning Response, a pattern of behavior that appears to be hard-wired into humans and pops up whenever somebody feels like they're suffocating in water
Frank Pia, PhD, the psychologist and lifeguard described the Instinctive Drowning Response as: [quote]1 Except in rare circumstances, drowning people are physiologically
Yet another sign that machines are about to take over the world, this autonomous flying helicopter can do aerial flips and landings all by itself
Control of precise aggressive maneuvers with an autonomous quadrotor helicopter This is a small autonomous Unmanned Aerial Vehicle UAV Demonstrations of flips, flight through windows, and quadrotor perching are shown Work done at the GRASP Lab, University of Pennsylvania

NASA's next Mars rover, Curiosity, is sitting pretty on a set of spiffy new wheels that would be the envy of any car show on Earth
The wheels and a suspension system were added this week by spacecraft technicians and engineers These new and important touches are a key step in assembling and testing the flight system in advance of a planned 2011 launch
Curiosity, centerpiece of NASA's Mars Science Laboratory mission, is a six-wheeler and uses a rocker-bogie suspension system like its
Imagine being able to operate a computer interface in the real world by just using your hands, without any computer visible, for example to take a picture by merely putting your fingers in the shape in the picture below, and then project those images on a wall and sort them Well you can, and the cost is merely about $350
Another amazing TED presentation

Sitting up straight is not the best position for office workers as it places an unnecessary strain on your back The best position in which to sit at your desk is leaning back, at about 135 degrees
Experts said sitting was known to contribute to lower back pain
Data from the British Chiropractic Association says 32% of the population spends more than 10 hours a day seated Half do not leave their desks, even to have lunch Two thirds of people also sit down at home when they get home fr

From the creator of the Minority Report-style interface comes the next generation which will blow your mind
John Underkoffler was the tech adviser on the film, he was the guy whose work actually inspired the interfaces that Tom Cruise used The real-life system he's been developing since then, called g-speak, is unbelievable A must watch video
