Imagine if you could mold your mobile phone into your desired dimensions on a whim - Paddle Smartphone will make it true. IN the interest of creating a device flexible enough to transform from game controller to smartphone to tablet, a team of researchers from the Hasselt University have created 'Paddle', a device based on engineering principles behind 3-D puzzles.

Inspired by the Rubik's Magic,the team has been developing a puzzling prototype that can take 15 different shapes to date. If a Paddle user wanted to go from a smartphone to tablet, he or she would need to make just a few simple folds to get the device in its current state into the appropriate model the user wants it to be in.

The topology of the current Paddle prototype uses an optical tracking system with a projector for visual output. This obviously, impedes the device's mobility, but the group figures advancements in flexible electronics research over the next 5 to 10 years will allow them to jump from this system to something a bit more appropriate; a paddle that is entirely self-contained and uses integrated displays.

The novelty of Paddle is all the many forms it can take on. It can clam up to serve as a flip phone. It can also be folded up into a ring, and made into a book-like form so that the user can download a piece of literature and leaf through the pages as they would with a normal book.
Further down the road, the group intends to further explore how the system can assist in training users' muscle memory to do these complicated transformations unconsciously in a fraction of a second.

Want to charge your batteries faster? How about flat to full in 30 seconds?An Israeli start-up called StoreDot is attempting to save your precious time with its nano-crystal - based smartphone battery. But its still a prototype, and does not full capacity either. And they haven't shrunk the tech so its small enough to fit inside the phone. But the startup reckons the speedy recharging battery technology could be on the market within 3 years.

So, what are these nano-crystals? They're molecules produced by StoreDot that are comprised of chemically synthesized bio-organic peptide (amino acids) molecules. These molecules are tiny, which helps improve electrode capacitance and electrolyte performance. The reason it takes so long to charge batteries is because you're literally reversing the exact chemical reaction that caused the battery to die in the first place. These small molecules speed up the process by an incredible amount.

This idea has been attempted before, but those attempts generally used heavy metals (extremely toxic). StoreDot used bio-organic raw materials which are safe both to people and the environment, and the sheer abundance of organic material on Earth makes them more affordable. StoreDot CEO and founder Doron Myersdorf says,"In essence, we have developed a new generation of electrodes with new materials - we call it MFE - Multi Function Electrode. On one side it acts like a super capacitor (with very fast charging), and on the other is like a lithium electrode (with slow discharge). The electrolyte is modified with our nano-crystal in order to make the multi-function electrode more effective"

StoreDot's original focus for the nano-crystals was memory chips - which could write faster thn taditional falsh memory. It has also demoed an image sensor using the technology. But it's now shifted its focus to what it sees as the two most promising near-term routes to commercialize the technology: fast charging smartphone batteries, and cadmium-free displays - with its nano-crystal tech offering a cheaper and non-toxic alternative to cadmium in screens.

StoreDot is seeking patents, with mass production planned for late 2016. So, presuming it works, this means a lot more than just less waiting time. It could also change the feasibility of using electric car. We could charge our cars in less than 30 seconds, that would be great!

Have you ever visited a store for the first time and felt eerily familiar? Or maybe had a conversation with your friend and felt that you had the exact conversation before, even though you know you haven't. If you've ever found in a similar situation then you've experienced déjà vu. 60 to 70 percent of us have experienced déjà vu. The sight, sound, taste or even smell of something makes us think that we've experienced it before, although we haven't.

Déjà vu is a French term that literally means "already seen" and has several variations. There are more than 40 theories to what déjà vu is and what causes it. We'll explore through a few of these theories and shed some light on this phenomenon.

Dual Processing(or Delayed Vision)

---

This theory is based on the way our brain processes new information and how it stores long- and short-term memories. Robert Efron tested an idea that stands as a valid theory even today. He proposed that a delayed neurological response causes déjà vu. Because information enters the processing centers of the brain via more than one path, it is possible that occasionally that blending of information might not synchronize correctly.

Divided Attention(or cell phone theory)

---

Efron found that the temporal lobe of the brain's left hemisphere is responsible for sorting incoming information. He also found that the temporal lobe receives this incoming information twice with a slight(milliseconds) delay between transmissions - once directly and once again after its detour through the right hemisphere of the brain. If that second transmission is delayed slightly longer, then the brain might put the wrong time stamp on that bit of information and register it as a previous memory because it had already been processed. That could explain the sense of familiarity.

Dr. Alan Brown has attempted to recreate a process that he thinks is similar to déjà vu. In studies at Duke University and SMU, They showed photographs of various locations were familiar. Prior to showing them some of the photographs , however, they flashed the photos onto the screen at subliminal speeds (10-20milli seconds) which is long enough for the brain to register the photo but not long enough for the student to be consciously aware of it. Th imaged that had been shown subliminally were familiar at a much higher rate than those that were not, even those who had actually been to those locations.

Based on this idea, Alan Brown proposed what he calls cell phone theory (divided attention). This means we are distracted with something else, we subliminally take in what's around us but may not truly register it consciously. Then, when we are able to focus on what we are doing, those surroundings appear  to already be familiar to us even when they shouldn't be.It would work like this : before we've actually looked at thee room, our brains have processed it visually and/or by smell or sound, so that when we actually look at it we get a feeling that we've been there before.

Hologram Theory

---

Dutch psychiatrist Hermon Sno proposed the idea that memories are like holograms, meaning that you can recreate the entire three-dimensional image from any fragment of the whole. Déjà vu happens when some detail in the environment we are currently in is similar to some remnant of a memory of our past and our brain recreates an entire scene from that from fragment.

Although déjà vu has been studied as a phenomenon for over a hundred years and researchers have advanced tens of theories about its cause, there is no simple explanation for what it s and why it happens. Still the dual processing theory is still considered more logical and valid. Perhaps as technology advances and we learn more about how the brain works, we will learn more of this phenomenon.
