The MiniScanEYE Digitizes Text For On-the-Go Reading Pleasure...

Being able to scan text is a convenience that can be easily achieved with the MiniScanEYE that allows for wirelessly converting books into computer documents. Designed to look like a simple pen, the MiniScanEye can be dragged across a page to quickly copy the text to a nearby device.
The MiniScanEYE is a fantastic tool for students who are constantly writing essays and need to be able to take quotations a rapid rate. Although small and simplistic in design, the MiniScanEYE runs over $260, which means that it might be a luxury not everyone can justify.
With that said, the MiniScanEYE is fantastic innovation for those who want to quickly copy bits and pieces of text or large quantities in a snap for easy augmentation.

World First Underwater Car..!!!

The sQuba, developed by Swiss company Rinspeed, is the world’s first car that can be driven both on land and under water.
The original idea by Rinspeed founder and CEO Frank M. Rinderknecht was inspired by the 1977 James Bond film The Spy Who Loved Me. The chassis from the Lotus Elise is used as the base for this vehicle.
The sQuba is a zero-emission, all electric vehicle which uses three electric motors, one for land travel, two for water. It drives on land powered by its electric rear-wheel drive powertrain, utilizing rechargeable lithium-ion batteries. Upon entering water, it floats on the surface until the operator floods the interior to submerge it. It can be submerged to a depth of 10 metres (33 ft), powered by twin electric-powered propellers supplemented by two Seabob water jets. It “flies” when underwater, like a submarine, as it is not designed to drive along the surface at the bottom of the water. The car’s top land speed is 120 km/h (75 mph). On the surface of water, the top speed is 6 km/h and underwater it is 3 km/h

We knew it was being rebuilt, but as these amazing new designs show, it really WILL be 1912 all over again....

There will not be televisions or state-of-the-art music systems on board, nor internet connections or   mobile phones. But every passenger will find period costumes in their cabin wardrobe so that they can enjoy ‘a true 1912 experience’.
However, the plans include a safety deck (with more lifeboats obviously), a new high-tech engine, air-conditioning and service lifts. 
As with the original ship, there will be First, Second and Third Class cabins and passengers will not be allowed to mingle – apart from on the safety deck, where there will be a casino and theatre.


And at 883ft, Titanic II will be three inches longer than its predecessor to accommodate an additional area at the bow where passengers will be able to recreate the iconic ‘Jack and Rose pose’ made famous by actors Leonardo DiCaprio and Kate Winslet in James Cameron’s 1997 Oscar-winning movie.
Cameron refused Palmer’s invitation to last week’s Titanic II celebratory gala dinner in New York. 
Another dinner was held last night at London’s Natural History Museum, where guests were served the same 11 course dinner as First-Class passengers on the original.
   


Speaking to The Mail on Sunday yesterday, Prof Palmer said he would travel Third Class on his  ship’s maiden voyage – ‘Although I’ll probably nip up to First or the bridge as we come into New York harbour,’ he said. 
‘Third Class has got all the appeal, but there might be people who normally travel Third Class who might want to go in First.’
Known as the man who got rich under the radar, Palmer was born in Melbourne to Nancy and George Palmer, a silent movie star of the 1920s who went on to set up the first commercial radio stations in Australia.
Clive made his first millions investing in property on Australia’s Gold Coast but became eye-wateringly rich after moving into iron ore mining.
His net worth is the subject of much debate. Business Review Weekly rates Palmer as Australia’s fifth-richest person with assets of $5 billion (about £3.5 billion) while Forbes estimates his wealth at a relatively paltry $895 million (£600 million).


Palmer contends he is far wealthier than even the BRW estimate. He refuses to say how much Titanic II will cost to build, although   experts believe it will between £260 million and £400 million.
While the original was built in Belfast, this ship will be constructed in a Chinese yard, and the voyage could become a financial bonanza for Palmer. 
But he says: ‘My motivation   wasn’t to make a lot of money but was actually to deliver the ship. Now something which wasn’t primarily aimed in my mind as a great business transaction may well become one.’

Will.i.am wants to open creative factory.....

Singer Will.i.am is keen to create a platform for creative people. He hopes it will give them the freedom to produce whatever they like.

The 38-year-old is inspired by Johnny Depp's movie "Charlie and the Chocolate Factory", where the actor's character Willy Wonka has a magical factory that produces the best chocolate in town, reports dailystar.co.uk.

"I want a Willy Wonka factory one day, just a creative campus of creative indi-viduals coming up with things," Will.i.am said
"One day I'm going to have 10,000 people working in this business. I am rethinking the Segway," he added.

Prince of Persia The Shadow and the Flame goes mobile..

Any number of video games can trace their roots to Prince of Persia: Assassin's Creed, Tomb Raider, even endless runners like Mirror's Edge and Vector.
But what of that legendary original? Last year, Prince of Persia Classic made its iOS debut, and for those who have been eagerly awaiting the sequel, it has arrived: Prince of Persia The Shadow and the Flame.
Originally known as Prince of Persia 2, the game was released by Broderbund (remember them?) way back in 1993 (remember when?). Twenty years later, it looks significantly better, with 14 gorgeously rendered levels spanning five different environments.
For those too young to remember the series, Prince of Persia combines run-and-jump platforming action with puzzle solving and occasional bouts of combat.
But there's a plot, too; one that picks up soon after the original game: The Prince, arriving at the castle to claim his princess, is deceived by the evil Jaffar and must flee the city. Adventures ensue.
The mobile game promises touch-screen-optimized controls and a brand new combat system. At press time, I wasn't able to give it a proper test, but the user reviews on both Google Play and the App Store average around 4.5 stars.
By the way, while we're looking back at game history, the original Prince of Persia was created by Jordan Mechner, whose earlier classic Karateka was revamped for iOS late last year. If PoP2 is anywhere near as good, you're in for a treat.
Prince of Persia The Shadow and the Flame is available now for $2.99. If you've tried the game already, hit the comments and share your opinion.

Aireal: Disney tests air-flow tactile gaming technology....

Gamers could be able to feel the thwack of a ball or bullets whooshing past their faces if Disney's experimental air-flow technology takes off.
Dubbed Aireal, the technology allows users to feel physical feedback from virtual images without having to wear gloves, belts or vests.
Puffs of compressed air blown at different strengths and speeds simulate tactile experiences, the inventors say.
It is the latest innovation in haptic - or tactile - technology.
Air vortices pumped through 3D-printed flexible nozzles directed by motion sensors can simulate anything from the gentle flap of a butterfly's wings to the hard impact of a ball hitting the hand, say developers at the University of Illinois and Disney Research.
But the technology is at a very early stage of development.
While motion sensors have allowed gamers to interact with 2D screens without the need for hand-held controllers, haptics aims to make these virtual experiences tactile as well.
"This is obviously just a proof of concept at this stage," said Prof Vic Grout, head of computing at Glyndwr University. "But it could have some very interesting applications in the gaming and non-gaming worlds.
"Most people interact more naturally with computer systems through touch or movement, and gesture-controlled interfaces are now well established.
"The big breakthrough for Disney's technology will come if they can make it mobile."
Disney was showing off its new technology at the Siggraph conference in Anaheim, California.

Microchips Mimic Brain's Processing Power....

Researchers in Switzerland say they have made microchips that imitate the way our brains process information, unlocking some of the mystery around how the world's most efficient computer functions.
Scientists at the University of Zurich and ETH Zurich, together with colleagues in Germany and the United States, created electronic systems comparable to a human brain both in size, speed and energy consumption, the university said in a statement late Monday.

Photos: Anything You Can Do, Robots Can Do Better



The Blue Brain Project is working to build a human brain- inside a supercomputer.
NIH
Just like the brain, their so-called neuromorphic chips are capable of processing and reacting to information in real-time, it said.
"The challenge is to build something as close as possible to an actual brain," Giacomo Indiveri, a University of Zurich professor of Neuroinformatics and one of the researchers on the project, told AFP.
Electronic systems in the past have been designed to react to their environments, as with blinds that automatically close when sunlight hits them.
But, said Indiveri, the new project takes things further.
Using neuromorphic chips as artificial neurons, the researchers built networks that can perform tasks requiring short-term memory and decision-making and analytical abilities, Indiveri said.

Computers Can 'See' People's Dreams

The technology could over time become a useful tool, allowing robots to "navigate autonomously in an environment and survive without someone with a remote control," he said, adding that the chips might also help make smart phones even smarter.
The chips could also one day pave the way for computers that can function despite faulty parts, in the same way the human brain continues to churn unabated even though it loses around a million neurons each day.
The findings are published in the US journal Proceedings of the National Academy of Sciences (PNAS).

Watch: Buiding that can 'eats' smog in Mexico city..


A building in Mexico City is doing its bit to save the environment. The hospital tower has a very unique feature, it 'eats' smog. The facade is coated in a special material which when is hit by sunlight's ultraviolet rays begins to break down pollutants into less harmful substances. The designers say it neutralizes the effect of 1,000 cars a day.

Archaeologists discover dinosaur tail in northern Mexico....

A team of archaeologists have discovered the fossilized remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico, the country's National Institute for Anthropology and History (INAH) said on Monday.
Apart from being unusually well preserved, the 5 meter (16 foot) tail was the first ever found in Mexico, said Francisco Aguilar, INAH's director in the border state of Coahuila.
The team, made up of archaeologists and students from INAH and the National Autonomous University of Mexico (UNAM), identified the fossil as a hadrosaur, or duck-billed dinosaur.
The tail, found near the small town of General Cepeda, likely made up half the dinosaur's length, Aguilar said.
Archaeologists found the 50 vertebrae of the tail completely intact after spending 20 days in the desert slowly lifting a sedimentary rock covering the creature's bones.
Strewn around the tail were other fossilized bones, including one of the dinosaur's hips, INAH said.
Dinosaur tail finds are relatively rare, according to INAH. The new discovery could further understanding of the hadrosaur family and aid research on diseases that afflicted dinosaur bones, which resembled those of humans, Aguilar said.
Scientists have already determined that dinosaurs suffered from tumors and arthritis, for example.
Dinosaur remains have been found in many parts of the state of Coahuila, in addition to Mexico's other northern desert states.
"We have a very rich history of paleontology," Aguilar said.
He noted that during the Cretaceous period, which ended about 65 million years ago, much of what is now central northern Mexico was on the coast. This has enabled researchers to unearth remains of both marine and land-based dinosaurs.

The presence of the remains was reported to INAH by locals in June 2012. After initial inspections, excavation began earlier this month. The remains of the tail will be transferred to General Cepeda for cleaning and further investigation.

Assassin’s Creed 4 Main Campaign To Last Around 15-25 Hours ........


Assassin’s Creed 4: Black Flag is shaping up to be a solid entry in the Assassin’s Creed franchise. With a massive world to roam around and over 50 locations to explore, Assassin’s Creed 4 looks like it will be returning to its roots.

We caught up with creative director Jean Guesdon and asked him about the length of the main campaign in Assassin’s Creed 4. He said that it will last around 15-25 hours.
“It’s hard to gauge since open-world exploration is such an important part of our game. You need to explore the world to become stronger, and to access some of the later missions. In this respect, the main path takes around 15-25 hours, but the totality of the content in the game takes a lot longer to complete,” Guesdon said.
In my opinion 15-25 hours is a pretty solid length and as Guesdon points out, it may take longer for the exploring type of player.

Guesdon also explains that how next generation version of Assassin’s Creed 4 has actually made the current generation version of the game better.

“We are very open about the fact that we are a cross-gen title. This means that we have to develop for both current-gen and next-gen platforms. This obviously means that we had to do a lot of lateral thinking, but the reward is that features that we developed for Next-Gen ended up becoming feasible on current-gen. One example is the companion app: this was at first an exclusively next gen feature but it became such an integral part of our game, such a cool feature, that we put in the effort to make it available for everyone. So yes, in this sense, next gen really shaped some aspects of the game that you can experience across all platforms,” he added.

Birds, humans have similar brain wiring...

Humans and birds have brains that are wired in a similar way, a new study has claimed.
A researcher from Imperial College London and his colleagues have for the first time developed a map of a typical bird brain, showing how different regions are connected together to process information.
By comparing it to brain diagrams for different mammals such as humans, the team discovered that areas important for high-level cognition such as long-term memory and problem solving are wired up to other regions of the brain in a similar way.
This is despite the fact that both mammal and bird brains have been evolving down separate paths over hundreds of millions of years.
The researchers suggest that evolution has discovered a common blueprint for high-level cognition in brain development.
Birds have been shown in previous studies to possess a range of skills such as a capacity for complex social reasoning, an ability to problem solve and some have even demonstrated the capability to craft and use tools.
“Birds have been evolving separately from mammals for around 300 million years, so it is hardly surprising that under a microscope the brain of a bird looks quite different from a mammal,” said Professor Murray Shanahan, author of the study from the Department of Computing at Imperial College London.
“Yet, birds have been shown to be remarkably intelligent in a similar way to mammals such as humans and monkeys. Our study demonstrates that by looking at brains that are least like our own, yet still capable of generating intelligent behaviour, we can determine the basic principles governing the way brains work,” Prof. Shanahan said.
The team developed their map by analysing 34 studies of the anatomy of the pigeon brain, which is typical for a bird.
They focussed on areas called “hub nodes”, which are regions of the brain that are major centres for processing information and are important for high level cognition.
In particular, they looked at the hippocampus, which is important for navigation and long-term memory in both birds and mammals.
They found that these hub nodes had very dense connections to other parts of the brain in both kinds of animal, suggesting they function in a similar way.
They compared the prefrontal cortex in mammals, which is vital for complex thought such as decision making, with the nidopallium caudolaterale, which has a similar role in birds.
Researchers discovered that despite both hub nodes having evolved differently, the way they are wired up within the brain looks similar.

Three dragonfly species discovered in China....

 Scientists have discovered three dragonfly species, indigenous to China, inhabiting the Shennongjia nature reserve, a researcher said Friday. 

"The three new Cephalaeschna species are found nowhere else in the world but central China," Zhang Haomiao, an aquatic animal researcher from the Chinese Academy of Sciences, was quoted as saying by Xinhua. 

He said the species can be "used" to monitor water quality, as they live only in the relatively pristine streams and cannot tolerate polluted water. 

The dragonflies also do not like sunshine and only become active after dusk, he said. 

The scientists' findings have been published in the International Journal of Odontology. 

The Shennongjia nature reserve in a Unesco world heritage site in Hubei province. According to official statistics, there are approximately 1,131 species of plants, 54 kinds of animals, 190 species of birds, and several types of reptiles and amphibians.

Now, human pee to charge cellphones...



Pee power! In a world first, UK scientists claim to have developed a novel method to charge mobile phones - using human urine. 

Scientists working at the Bristol Robotics Laboratory have described the "breakthrough" finding of charging cell phones using urine as the power source to generate electricity. 

"We are very excited as this is a world first, no-one has harnessed power from urine to do this so it's an exciting discovery. Using the ultimate waste product as a source of power to produce electricity is about as eco as it gets," Dr Ioannis Ieropoulos from University of the West of England (UWE), Bristol, an expert at harnessing power from unusual sources using microbial fuel cells, said. 

"One product that we can be sure of an unending supply is our own urine. By harnessing this power as urine passes through a cascade of microbial fuel cells (MFCs), we have managed to charge a mobile phone. The beauty of this fuel source is that we are not relying on the erratic nature of the wind or the Sun, we are actually re-using waste to create energy," said Ieropoulos. 

He said so far the microbial fuel power stack that scientists have developed generates enough power to enable SMS messaging, web browsing and to make a brief phone call. 

"Making a call on a mobile phone takes up the most energy but we will get to the place where we can charge a battery for longer periods. The concept has been tested and it works - it's now for us to develop and refine the process so that we can develop MFCs to fully charge a battery," he said. 

The Microbial Fuel Cell (MFC) is an energy converter, which turns organic matter directly into electricity, via the metabolism of live microorganisms, researchers said. 

Essentially, the electricity is a by-product of the microbes' natural life cycle, so the more they eat things like urine, the more energy they generate and for longer periods of time; so it's beneficial to keep doing it, they said. 

The electricity output from MFCs is relatively small and so far we have only been able to store and accumulate these low levels of energy into capacitors or super-capacitors, for short charge/discharge cycles. 

This is the first time we have been able to directly charge the battery of a device such as a mobile phone and it is indeed a breakthrough, researchers said. 

Scientists believe that the technology has the future potential to be installed into domestic bathrooms to harness the urine and produce sufficient electricity to power showers, lighting or razors as well as mobile phones. 

The study was reported in the Royal Society of, 'Chemistry Journal of Physical Chemistry Chemical Physics'.

Lernstift smart pen vibrates when you make spelling error....

Lernstift smart pen vibrates when you make spelling error. Rapidly changing technology has indeed made this world smart. From smart phones to smart TVs, the gadgets are becoming smarter with each passing day. A smart-pen has been developed by the Germans that is capable of detecting the spelling errors being committed by the user. Besides the errors, if the user’s handwriting is sloppy then also the pen would start issuing warnings by vibrating continuously.
Called Lernstift, the smart pen is quite similar to a regular pen and works requires the real ink to write. It is fitted with a special motion sensor and a small battery-powered Linux computer with a WiFi chip that brings together the smartness factor in the pen. The specific movements, letter shapes and know a wide assortment of words are recognised by the pen with the help of the installed technology.
The idea behind making the pen that is the brain child of Falk Wolsky came after he saw his 10-year-old son doing his homework. Speaking about the project, the other co-founder Daniel Kaesmacher said: “His son had been struggling with his work and staying focused and Falk thought there should be a pen that gives him some sort of signal so he stays focused. Users can choose between two functions: Calligraphy Mode – pointing out flaws of form and legibility or Orthography Mode – recognising words and comparing the word to a language database. If the word isn’t recognised it will vibrate.”

LG claims thinnest HD LCD smartphone display...

LG Display said Thursday it has developed the world’s thinnest full HD LCD display for smartphones, measuring just 2.2 millimeters thick.
The company said its new 5.2-inch (132 mm) display panel has a resolution of 1,080 by 1,920 pixels and is brighter than current full HD phone panels on the market. LG did not reveal when the panel will become available on the market, but showed images of it working and said its results had been independently verified by testing firm Intertek. LG Display said the screen’s bezel is a fraction thicker at 2.3 mm.
LG said it has used a new in-house technology it calls “Advanced One-Glass-Solution.” One-glass solution technology, or OGS, puts the touch screen layer of a display directly onto the underside of the cover glass, combining the two. This eliminates the need for a separate touch-screen layer and allows more light through. It also has the potential to make manufacturing simpler and save costs.
Displays, batteries and camera modules are among the thickest components in smartphones. Slim designs and low weight have proven to be major motivators for consumers for consumers, and so manufacturers are eager to flatten their devices. The display and touch screen together make up the most expensive component on a smartphone, followed by NAND flash memory and the main processor.
Last month, China’s Huawei announced it will soon launch the world’s thinnest smartphone, the Ascend P6, which is just 6.18 mm thick. Apple’s iPhone 5 is 7.6 mm thick, while Samsung’s Galaxy S4 measures 7.9 mm.
Last year, LG Display was the fourth-largest manufacturer of the small and medium-size displays used in smartphones and tablets by revenue, according to data vendor NPD DisplaySearch. LG had a 12 percent market share, behind Samsung Display at 23 percent, Japan Display at 15 percent, and Sharp at 13 percent.

New atomic clock may 'redefine the second'.

A new type of atomic clock may be a more accurate way to measure time, scientists say.
The French researchers said the new device, called optical lattice clock, lost just one second every 300 million years.
Currently, atomic clocks are used to count the seconds, but the new clocks proved to be more precise in tests and offered a better system for defining the second, researchers said.
The atomic clock has proved to be quite an accurate method of keeping the world on time and since the 1960s has been used to define a second in the International System of Units (SI units).
Now scientists in journal Nature Communications, claim the optical lattice clock could improve the precision.
Just as a grandfather clock uses the swing of a pendulum to measure intervals of time, an atomic clock uses the very regular "vibrations" of atoms, the 'BBC' reported.
The current systems, called caesium fountains, expose clouds of caesium atoms to microwaves to get them to oscillate. But the the new ones use light to excite strontium atoms.
"In our clocks we use laser beams. Laser beams oscillate much faster than microwave radiation, and in a sense we divide time in much shorter intervals so we can measure time more precisely," said Dr Jerome Lodewyck, from the Paris Observatory.
The optical clocks are three times as accurate as caesium fountains, which are accurate to one second every 100 million years.
As well as comparing the optical lattice clocks with the current atomic timekeepers, the researchers compared two optical clocks with each other. They found that they kept time in agreement, and were also very stable.
Many technologies such as telecommunications, satellite navigation and the stock markets rely on ever-better time measurements. The researchers said the new clocks could one day help to redefine the second.

Hubble telescope discovers alien 'deep blue' planet...

The ageing space telescope has been used to identify the true colour of a planet beyond our solar system for the first time.
The heavens are home to an alien world that shines a deep cobalt blue in a solar system far, far away from our own.
Astronomers used the ageing Hubble space telescope to determine the true colour of the distant world, the first time such a feat has been achieved for a planet that circles a star other than the sun.
Unlike the pale blue dot that harbours all known life in the cosmos, the "deep blue dot" is an inhospitable gas giant that lies 63 light years from Earth. On HD189733b, as the planet is named, the temperature soars to 1,000C and glassy hail whips through the air on hypersonic winds.
Though the planet is hostile to life as we know it, the same technique could be used to spot potentially habitable worlds, through changes in cloud cover and other features.
Frederic Pont at Exeter University observed the planet before, during, and after it passed behind its star. When the planet was on either side, the telescope collected light from the star along with light reflected from the planet's surface. But as the planet moved behind the star, the light it reflected was blocked out.
Using an instrument onboard the telescope called an imaging spectrograph, Pont noticed that blue light dimmed sharply as the planet passed behind its star, but brightened again when it emerged on the other side. "As far as I am aware, nobody has had actual results on the colour of an exoplanet," Pont said. "Now we can say that this planet is blue."
The deep cobalt colouration is thought to come from a similar process to that which makes Earth look blue from space, namely the scattering of blue light in the atmosphere. On the planet Pont observed, the scattering is probably due to a fine mist of silicate particles that are blown around by 7,000kph winds.
With more advanced technology, the colour of a planet could help astronomers work out which ones might be habitable. Most planets in our solar system are either entirely covered by cloud, or have no clouds at all. Earth is unusual in that roughly half of its surface is obscured by cloud, a product of the water cycle that is essential for life.
"If you could see the colour of an exoplanet change over time it would be very revealing. At first, the cloud cover would be the thing to go for," Pont said.
While future instruments could be sensitive enough to observe the changing hues of alien worlds, there may be no suitable telescopes in space to put them on. The Hubble observatory is more than 20 years old and was last repaired by a dedicated space shuttle mission in 2009. Without Hubble, there are no other space telescopes that could look at planets in visible wavelengths. Hubble's replacement, the James Webb Space Telescope, will pick up infra-red light only.
"Most colleagues in the field focussing on habitability concentrate on the detection of molecules in the infra-red, like water, carbon monoxide and methane," Pont said. "That's useful information of course, but my opinion is that we might be giving too much weight to this compared to visible colour, which gives a different kind of information, but maybe just as crucial to understand the general state of an Earth-like planet."

Now, earthworm poop can help reveal climate history

Earthworm poop could provide a window into past climates, allowing scientists to piece together the prevailing weather conditions thousands of years ago, researchers say.

A laboratory study by scientists from the Universities of Reading and York has demonstrated that balls of calcium carbonate (small lumps of chalk-like material) excreted by the earthworm Lumbricus terrestris maintain a memory of the temperature at which they were formed.
This means that calcite granules, commonly recorded at sites of archaeological interest, have the potential to reveal information about past climates which could be used to enhance and benchmark climate change models, according to the study published in the journal Geochimica et Cosmochimica Acta. "These chalk balls will allow us to reconstruct temperatures for specific time intervals in which they were formed. Reconstructions like this are interesting for archaeologists, because they give a climatic context to their finds," said lead author Dr Emma Versteegh from the Department of Geography and Environmental Science at the University of Reading.
