Scientists developed a camera that can depict how light moves. It has a shutter speed of one trillion frames per second!

MIT scientists have developed a remarkable camera that can depict the movement of light! The camera captures images 40 billion times faster than a standard HD camera and has a shutter speed of approximately a trillion frames per second!

It is impossible to directly record light at that speed, so the camera takes millions of repeated scans to recreate each image. The process is called femto-photography. "There's nothing in the universe that looks fast to this camera," said Andrea Velten, one of the researchers involved in the project.

The technique was created by scanning one, thin horizontal line at a time by using an adapted streak tube. One image is equivalent to a single scan line, and hundreds of images had to be taken to create one frame. The scientists did this by repeating each shot, angling the camera's view with mirrors to record a different scan line of the object every time.

This camera has revealed new ways of seeing the world and it can also be used to analyze faults and material properties, scientific imaging for understanding ultra-fast processes and medical imaging to reconstruct sub-surface elements—ultrasound with light!

The camera can even capture the scattering of light below the surface of solid objects!


Japanese robot-maker Cyberdene develops robotic legs — not Terminators!

Japan is a technologically rich country and has employed industrial robots for the longest time. A robotic suit that will, in future assist the elderly and the disabled to stand and move around has been developed by Japanese robot-maker Cyberdene. It has now received a global safety certificate.

HAL, short for Hybrid Assistive Limb, is a pair of robotic legs that can be attached to the legs of a disabled or aged person. It will help them move around like a normal person. The artificial limb was not the first artificial limb made by Cyberdene. The company has made robotic arms in the past, too.

This opens up a whole new world of opportunities for disabled people to move around freely. For now it will be used to help patients rehabilitate from nerve and muscle illnesses. The robot suit HAL will be used by ten hospitals in the first clinical trials of it's kind.

Cyberdene is based in Tsukuba, northeast of Tokyo and has rented out approximately 330 suits to about 150 hospitals and welfare organisations. To clarify, Cyberdene is not to be confused with the firm of the same name in the movie ‘Terminator’ and HAL is not related to the evil supercomputer from Stanley Kubric’s ‘2001:A Space Odyssey’ either.


It would have cost NASA more to fake the first moon landing than it would have to just land on the moon!

Conspiracy theorists love to deny the moon landing ever happened and they point out a number of reasons that "prove" the historical moment was faked in a studio. The fact is, we had the technology to land on the moon, but we did not yet have the technology to fake it in 1969!

Conspiracy lovers argue that the film was shot on Earth and then just slowed down to emulate the minus-gravity effect of the astronauts strolling around on the moon. However, the camera required to do that didn't exist at the time.

Slow motion video can only be done in one of two ways. You can shoot video at normal speed and slow down the playback, or you can film it at high speed and play it at normal speed.

The second way is called overcranking, and produces a smoother picture. In 1969, this was only possible with film cameras and anybody who knows anything about cameras and filming knows the moon landing was definitely not shot with a film camera.

It would actually have cost more to develop all the technology conspiracy theorists say was used to fake a moon landing in 1969, than what it did cost to just go to the moon and do a real moon landing!


Some awesome lists!

Kevin Warwick is the first cyborg to walk the earth. Are cybernetics coming to a body near you?

Inspector Gadget was just a movie. But could it come true? Scientist Kevin Warwick thinks so. He's gone so far as to make himself part robot.

Warwick is a professor of cybernetics at Reading University. Apparently Warwick said "I want to do something with my life; I want to be a cyborg." At first this might not make sense.

In 1986, he had a silicon chip transponder inserted into his arm that enabled him to operate doors and lights. He planned to have another chip inserted. His goal was noble—to save humankind through technology.


TiME is a seafaring probe designed to explore the lakes and seas of Saturn's moon Titan's. So why didn't NASA launch it?

On 22 July 2006, lakes and seas were discovered on Titan, Saturn's largest moon. These are located in Titan's northern hemisphere. The discovery confirmed the hypothesis that liquid hydrocarbons exist on Titan. Most of Titan goes centuries without seeing any rain, but precipitation is expected to be much more frequent at the poles.

Titan Mare Explorer (TiME) was designed to land on Titan and would have performed the first nautical exploration of an outer space sea. It was to analyse the nature of the seas and explore the shorelines. The target lake was Ligeia Mare (78°N, 250°W). It is one of the largest lakes of Titan identified to date, with a surface area of about 100,000 km2.

TiME was one of three Discovery Mission finalists that received US $3 million in May 2011 to develop a detailed concept study. The other two missions were InSight and Comet Hopper. After a review in the Summer of 2012, NASA announced in August 2012 the selection of the InSight mission to Mars.

The chance to discover a form of life with a different chemical basis than life on Earth has led some researchers to consider Titan the most important world on which to search for extra-terrestrial life.
