Robots changing their shape


The more research of Artificial Intelligence the more we get of Robots.Human automation is being more advanced with time but the problem remain same i,e rigidity.Robots are made of metals and other hard materials,although the skeletal structure are same as humans but remains stiff and inflexible.



However this scenario might change in the near future since some researchers from MIT and other universities of USA have developed a material that will allow the robots to be soft.Using a 3D printed phase changing material composed of polyurethane foam and wax researchers can use heat variances to manipulate the softness and hardness of the structure.


The prototype model was a snake robot.Their objective was to allow it to enter into a 1 cm opening and reach the other side.The use of foam and wax makes the whole process more affordable and simple.Other application of the same technology would even allow the robots to self heal but that is still in infancy stage.

  Quantum Internet

 

When we are in information superhighway the big concern is how to keep our data secure.And we are almost done.Researchers have been working on quantum technology to secure internet.This upcoming technology is known as quantum key distribution or QKD.

In China and Switzerland quantum technology is used to encrypt messages as a experiment.

Using this technique the network transmit photons in specific quantum states to create a cryptographic key.Using QKD data can be encrypted over non-quantum networks due to its mathematical complexity.

In order to decrypt the messages a very powerful computer is necessary.The beauty of the QKD is that if anybody try to hack the quantum key it would alter the quantum states of the photons and alerts the users.

At present the network range is restricted  due to the issues of quantum stability over long distances but that problem can be solved with the help of quantum repeaters.

Molecular Computers


In the near future computers may not be made of silicon but of DNA.DNA computers are much more faster and better than the traditional ones.

DNA is an information-rich molecule, and can be used for computing in a variety of ways. Computer chips are constructed using logic gates (such as AND, OR and NOT) that perform mathematical functions on given inputs. Similarly, these gates can be built from DNA, and connected up to run computations inside cells.


 

Brain-Computer Interface

 

Brain-computer interfaces(BCIs) plays a significant role in spinal cord injury,stroke or brain disease.It also helps to restore senses like sight or hearing or even memory.

BCIs implemented in brain's motor areas can record electrical signals thats represents particular movements. A computer decodes the signals and uses them to control a computer cursor or prosthetic limb.

The device would replace part of the brain's hippocampus, where short-term memory is converted to long-term memory. So far researchers has had success in rats and monkeys, and now they are  currently testing the device in humans.

Nanolasers on Silicon for Data Transmission

 

For quick transmission of data we rely on fiber optic cable.To ensure for more speed and seamless data flow researcher continue to new combinations of electronic and optical devices.

One of the promising research is growing lasers on silicon,the base layer of choice for electronic devices.

The lasers, called nanoneedles, are just one-tenth the width of a human hair and were developed by researchers working at the University of California, Berkeley. By growing lasers on silicon wafers, the researchers are expanding the ability of electronics to transmit data at capacities required by next-generation consumer devices and systems. 

Optical approaches such as lasers reduce power consumption and noise between components and increase speed.

To combine the strengths of silicon and optical laser materials, the Berkeley researchers overcame two longstanding challenges that have vexed researchers: 1) the mismatch between the crystalline structures of silicon and III-V semiconductor material, an essential solid-state laser material, and 2) growth temperatures that are incompatible with current integrated circuit fabrication. 
 
During the 10- to 15-minute crystal growth process, which occurs at temperatures between 400° and 450° C, nanoneedles in the shape of hexagonal pyramids emerge from a silicon base. These high-quality crystals can reach several hundred nanometers and can be layered, doped (i.e., other materials can be added to the crystal during the growth process, resulting in a crystal that has additional properties) or etched to create laser structures for device applications. The nanoneedle geometry provides a natural laser cavity that traps light by circulating it up and down the inside of the nanoneedle in a helical fashion.

7.Iptraf-ncurses-based IP LAN monitor.

8.Pmap-Reports memory map of a process thereby helping to find out the causes of memory bottlenecks

Li-Fi

 

Instead of radio waves, use light to get online. Unlike wi-fi, or wireless fidelity, so-called “li-fi” transmits data through variations in light intensity.

Recent research in China  showed that, using a one-watt LED bulb, li-fi could connect four computers to the Internet at data transfer rates up to 150 megabits per second.

Earlier this year, German scientists sent data at three Gigabits per second using LED lamps, in controlled conditions in their lab. They later demonstrated 500 megabits per second speeds in a real-world setting. Most wi-fi connections don’t even come close to 100 megabits per second.

Li-fi has drawbacks. The technology works only when the LED’s light can reach the gadget. Stray from the LED, and you lose your connection. On the plus side, the visible light spectrum can handle way more traffic than wi-fi’s already crowded radio spectrum. And any LED bulb can be a network connection.

BioLite CampStove

 

Stove with lots of technology in it.It runs on fuel you can pick up off the ground – twigs, bark or pinecones – providing you with a free, low-smoke fire.Its just take 5 minutes to boil a kettle.

But that’s not all – the BioLite also has a USB port and generates free electricity, which you can use to charge your phone, MP3 player or speakers.


Scanadu Scout

 

 

There are plenty of gadgets that monitor your fitness. Whether they track your heart rate, blood pressure or the number of steps you’ve taken, they all give you a pretty basic view of your activity. But what about your general health?

Designed by a collective of engineers, doctors and designers, the Scanadu Scout wants to be your personal electronic GP. By pressing it to your temple, the Scout will give you an accurate reading of pulse transit time, heart rate, electrical heart activity, temperature and blood oxygenation. This info in itself isn’t particularly useful, unless you’ve been nose-deep in some medical text books for the last year, so the Scout then analyses the data and tells you if you ought to head to the nearest hospital, or not.

There’ll be an add-on too, which will check your saliva for nasty bugs like streptococcus A, influenza B and adenovirus. They’re even working on an add-on to spot pregnancy complications.

All of the above is technically possible, and the collective data gathered from everyone using a Scanadu could reveal interesting trends in the state of the public’s health. But as with any mode of self-diagnosis, you should apply common sense. Either way, doctors might have to get used to hearing patients say: “I need an appointment. Scanadu says it’s serious”.

3D Printers

In Last December,2013 Michigan Technological University announced their firsr 3D printer.However not many of these printers is available to the common peoples.

Rocket parts,Bionic ears and even toothbrushes were all successfully printed with 3D printer.

3D printers use a variety of very different types of additive manufacturing technologies, but they all share one core thing in common: they create a three dimensional object by building it layer by successive layer, until the entire object is complete. It’s much like printing in two dimensions on a sheet of paper, but with an added third dimension: UP. The Z-axis.

Each of these printed layers is a thinly-sliced, horizontal cross-section of the eventual object. Imagine a multi-layer cake, with the baker laying down each layer one at a time until the entire cake is formed. 3D printing is somewhat similar, but just a bit more precise than 3D baking.
