"Electrification of bus"-London Buses runs on these new technology.

Hey,guys long time since i last wrotefor that i am sorry but i had some personal reasons for that but from now on its time for being regular.As we all know the double-decker bus transportation system in London is one of the most iconic features in the whole world.But as the world is advancing with the help of technology these buses are getting out-dated.So,the british government came up with idea that have changed the faith of the technology by which these buses are running and have once again poured water into the roots of a dead plant.Getting around London may not be the same again once a series of hi-tech upgradation are implemented in these type of transportation system.And not only in London but these technologies cxan be soon be applied to your city as well.

As per as recent surveys it had shown that these iconic red double-decker buses are getting a facelift too.As on roads around 8,700 buses are running around the city of London carrying around 6.5 million passengers a day.So,its really important to upgrade its redesign technology so that the transportation system can be more safe and fast.London is not only getting the power to cut emission but if new test by Transport for London(TfL) go well they will revolutionised the urban travel thanks to the recharging system that will kick the power topped up even when the bus is on the job.

So what are probably be the changes that Transport fot London(TfL) is bringing?
Actually in 2012 the London transport system came up with a new routemaster which has it power supplied by hybrid engine that gained various positive reviews from the car magazines as famous as "Autocar".So,basically what (TfL) is doing is that they are taking these technology one step further by using wireless charging.The plan is to keep the buses powered up even when the buses are running carrying passengers all over the city without having any unweildy charging cables involved.

What is these wirelessly chargable process?
The application of this technology is very simple.Actually what is happening is a very basic priciple of electricity.As said by Mike Weston,Director of Buses (TfL) that the red double decker buses runs for 19 to 20 hours a day so its is not possible at any way to put batteries on the buses so that it can produce more energy which can run the buses for such long hours without stopping.Even if they are putting batteries then for sure there wont be space left behing for the passengers to sit.So,the basic idea is that when the buses are generally coming to terminus or stoppage it will stand on a induction pad which transfer power to the buses at rate 10kW per every five minutes the bus stands at the terminus or a stoppage.The technology runs on as basic as the principle used in electric toothbrush which also produce charging without any electrical contact.The bus will have to be fairly parked over the induction pad constructed over the road.After the bus Parked itself it would have to lower down so that automatically the installed induction coil on the bus will attached to induction pad.

Mr.Weston also told we will have diesel fuel tank on the bus in case its running  late or get jammed in a traffic as a backup but most probably it will run on electric motor 80% of the time.He also mentioned by using these transportation method we can decrease the air pollution and can bring down the air quality control and CO2 level in the atmosphere.Its true that this process will surely decrease the air pollution and will revolutionise the way of bus transportation and i think not only london but many other countries especially India should take interest at this concept "Electrification of buses" and make diffrence to both transportation and environment.

"Potatoes could be the next electrical power that could light up the world."

Yes "Potatoes could be the next electrical energy that could light up the world"-you heard it right.This is exactly whats the future demands after rising increase of the electricity in the whole world and still 1.2 billion people lives in the darkness facing the scarcity of electricity.The ideas have been proposed from researcher rabinowitch and colleagues from the university of Hebrew,Jerusalem.The research team from year 2010 is trying to implement potato power to develop electricity to light the bulbs,LED's and run various other electrical appliances.

How the idea works?

This may be the most basic ideas of science that you may have already learned in your high-school.We all know that in order to make a battery from a organic material we will probably need two metals out of which one should be anode which is the negative electrode(metals like zinc) and another one is cathode which will act as a positive electrode(metals like copper),now the acid inside the potato will react with the two metals thus forming a "electron in flow" equation which will in turn release the energy.Actually this idea was first discovered in the 17th century when Galvani in 1780 attached two metals between the legs of a frog and for his surprise the leg muscle twitched letting him discover that metals will react and release energy if come in contact with a organic juice or acid.


Potatoes can be made more potentially compatible to produce more energy.The process is damn easy right.There is a smart and ingenious trick to make the potato release more energy so much that it can light up a bulb for as long as 40 days.The research team first looked at 20 different type of potatoes and measured their internal resistance and understand how much energy can be loss by heat.So what they did is that they boiled the potato for about 8 minutes which helped to broke down the organic tissues inside the potato and reduce the resistance and allows more free movements of the electrons thus producing more power.The research team told that the process is important because the cost of energy falls down thus its is economically sustainable.They analysed that a boiled potato can light a bulb at $9-per kilo-watt hour while a typical 1.5V AA-alkaline battery produces energy at the rate of $49-$55-per kilo-watt hour which is vast difference and can change the revolution of electricity.

But why "Potato Power" is not as famous as it should be?
The process being easy yet didn't the mark its presence in the world.when the question was asked to the research team they simply said that the most important reason for this is that most of the people are unaware of this fact that potato can be used as battery,the second most important factor comes when a food will be replaced as a source of energy where the united nation of food and agriculture would interfere as they did when sugarcane was being used as source of bio-fuel.And the third point could be the importance of potato in some continents like Asia and Africa where people's main food is mostly potato so telling them itself is a huge and difficult task.But though the difficulty is immense the research team said "we are improving slowly to spread our ideas and we hope that one day we will be able to spread it among the whole world for the betterment of it only"

Guys i think its a great idea as survey says every year more than a 10-20% potatoes go to the thrash because of poor harvesting or poor market conditions or even poor storage conditions.So we can easy use this waste potatoes as a source of electricity to save our world from the scarcity of the electrical energy.New ideas always ends in a good places and i hope one day this idea will aswell.

i Phone-More than just a phone.

Well in the field of mobile technology there's only one company that we all generally wait to see whats next technology and that what we all generally paraphrase as "Apple".This year like the previous one Apple didn't disappointed us as they bring out another brand new technology-its nothing but i phone-6.And this year its not only i phone but i phone-6 plus as-well.So let see what new features they have added to make this phone more cooler than ever.

The main motto of Steve Jobs for creating Apple was not to only advance the technology but to develop it along-with design and bring color to the technology and keeping that in mind even after his death the company is passing on his ideas and implementing it onto the technologies.Developing of  iPhone-6 and 6 plus have pushed the technology to the edge of another dimension.From the seamless transition of glass to the streamlined profile,every detail was carefully handled so that people can experience a overall brilliant experience.So,i am not going to bore with more facts on introduction but just give you the main features of this phone and why its being considered to be the best band in the world of mobiles.

As they said its not just bigger display but a better display.Yes making a bigger display is so common but making a better display is a challenge though.Its just what Apple did with i phone-6 with innovation that gives us new experience with high contrast with dual domain pixel for more accurate color at wider range and an improve polarizer,the most thinnest,the most advanced multi-touch display ever made is surely gonna give you a new view to life.Not only these but i phone-6 and 6 plus is hugely powerful and enormously efficient as its using 64-bit architecture wit M8 motion co-processor efficiently gathers more data from advance sensors and give you the fastest new barometer.Its technology doesn't stop here but continues with increase battery life which leads you to do more wide arrange of things for more time you have ever wanted.

Extremely Technology
Camera technology is more advance than any other smartphone as i-sight camera can now have new sensor with new focus pixels with 1080p hd ,slo-mo with 240fps that gives an experience of live-photo.When comes to the technology of wireless range it exceeds every limits as of being having the ability of the fastest LTE download speed. You can go to any area accessible of wi-fi and can very easily browse or download thing 3X times faster than any other mobile technology.Now every phone's first come priority is its security precautions and i-phone 6 have not dissapointed us in this even.The breakthrough ID technology can very securely guide you to access your mobile and its nothing but your Fingertips.

But the most important of all its feature is the operating system its based on and that's iOS 8 which is the world's most fastest and advance mobile operating system.And because of a larger display iOS 8 incredibly gives you a better experience with much more capabilities to go beyond technology and use your mobile as if you are touching life.So,if you are planning to buy i phone 6 or the other prototype don't think just give yourself a new life-experience.

FC Barcelona and Real Madrid started the new La Liga Campaign with a win.

 After World Cup we all were waiting for the opening day of the different club football leagues and the wait was finally over when La Liga was resumed on Saturday.La Liga considered to be one of the most competitive leagues not only in Europe but in the whole world hosts the two most fierce cub in europe none other than the two juggernauts of football world FC Barcelona and Real Madrid.So we will see how really these two teams performed on their opening day matches.

Barcelona who in the last season failed to win the title in the last match-day against Atletico Madrid were very excited to start the new campaign with a win to boost their confidence for the whole season.Though the starting eleven were lacking players like Ter Stegen,Suarez,Neymar,Xavi and Iniesta but the performance of FC Barcelona was yet excellent as they again proved that playing with coordination in a football field can help you win matches.

Barca's star player and the world's best Lionel Messi who was the captain of Argentina when they faced Germany in the WC 2014 clearly hinted his intentions when he scored two awesome goals in the opening match of the season.The Argentinian was brilliant for the whole match showing his skills and his vision of passing the ball and making co-ordination with team mates for which he his known.It was not only Messi who catched the world's attention but also a youngstar Munir El Haddadi who recently graduated from Barca B scored a brilliant chip over Elche's goal-keeper to give barca a 2nd goal.Barca's overall performance was superb with almost 72% ball possession they easily won the match 3-0 over Elche and surely gained confidence for the rest of the La Liga campaign.

While on the other part of Spain the mighty white Real Madrid went into their first Liga match with the sadness of defeat under the hands of neighborhoods Atletico Madrid in the super cup de espanna played just 3 days before.

Though it didn't affected their performance against Cordoba.Real Madrid got the lead in the opening 30 mins of the game when Benzema scored the goal.For the whole match Real Madrid had overall ball possession of 63% and the team were quite attacking but the 2nd goal came only in the dying minutes when Cristiano Ronaldo scored a 90 mins goal and create a new personal record of  being the only man to have scored against each and every team in La Liga.So,lets see what happens in the near future that what these two beasts can achieve in the further stages of the league and most importantly what happens when they face each other in El Classico.

Invisible materials are in the way of inventions.

Researchers in University of Cambridge are developing a new method using light to build a material which is realm of science fiction films.They are trying to develop a invisible material which can lead to the discovery of cloaking devices and cloaking cloths as well.Yes the same cloth that Harry Potter once wear in the fiction movie can now be seen in the real world.The technique is using light like a thread particle to produce long chains of molecules which can possibly bring the concept of sci-fi things like cloaking cloths and devices into reality.


So you may be wondering that how these could be possible as the basic properties of light is completely differing the theory.As of now what we know about light is that light when falls on a surface of a materials it is either reflected or absorbed which indeed enable us to see objects.So,this is the basic principle in which light theory is based on.But now by engineering materials kept at nano-scale level it is possible to produce meta-materials which are nothing but materials which has the capability to control the way in which light interacts with them.Light falling on meta materials generally reflects in a wrong way thus rendering the object invisible or making them appearing something else.

The Cambridge team is using the the technique by using unfocused laser light and stitching gold nano particles into thousands of long strings into the water for the first time.These layers then can be stacked into layers on top of the others simi8lar to that of the structure of Lego bricks.the method makes it possible to produce materials in higher quantities as compare to the techniques used currently.In order to make the strings the scientist have used a barrel-shaped molecules called cucurbiturils(CBs).The CBs acts as a miniature spacers which can bind the nano-particles quite tightly and helps to lock them strongly.Now what is challenging the scientist is that how the nano-particles can be connected electrically.Conventional welding techniques can be ineffective as they will melt most of the nano-particles.So the only method remains is building a bridge between the nano-particles.But the concept of these theory into practical application is quite challenging so the researcher is still working on it.



This technology to become reality is still a long road as first Scientists needs to precisely determine how to make the perfect meta-materials in the nano-scale level.But its possible soon enough because using light its quite possible to make this type of nano-constructions.I hope this Technology can indeed one day surprises the whole world and most important of all-change the world in a new way with better physical application

New device can save people suffering from memory losses!

Soon a device will be made which can help to restore your memory.Yes,you heard me right.DARPA(Defense Advance Research Project) have awarded a sum of 2.5 million dollar to Lawrence Livermore National Laborartory(LLNL) to make this implantable device which will have the ability to record and stimulate the neurons within the brain to help restore memory.The news have been recently announced.
The research will build up upon the theory that Memory is a process in which the neuron transmits or encodes signals at a particular regions of the brain,where it also store the information and retrieve it aswell.
But there are certain types of disease like Traumatic Brain Injury(TBI) or Alzheimer's Disease which generally disrupt this process and hence results in a memory loss.

What is this Device?
So,What (LLNL) researchers will do is that they will create this neural device which can uses real time recording and close-loop stimulation of neural tissues to bridge gaps in the injured brain and restores one individuals capability to access the old memories or to create one new memory.But for these the researcher first have to develop a new electronic system which can be named as neuromodulation system whose prime objective would be to find those areas of the brain which is linked with the memory so that they can find the information that where the new memories are formed.

How the Device will work?
The neural device that they are basically planning to develop is a miniature,wireless and chronically implantable one which will incorporate both single neuron and local field potential recording into a close loops system to implant into the TBI patient's brain.Generally the device will be implanted into the entorhinal cortex and the hippocampus part of the brain as because this two regions of the brain generally associates with memories.After the device is implanted it will allow to stimulate neural signal from the 64 channels of located on a pair of high density electrode arrays.

This arrays will be connected to the implantable electronic package capable of wireless data and power telemetry.An external device worn out of the ear will retrieve the digital signals associated with the memory storage and provide power telemetry to implantable package using a custom R-F coil system.The device's electrodes will be integrated with advance LLNL's integration and 3-D packaging technologies.While the micro-electrodes which will be the heart of this device will be embedded  in a bio-compatible flexible
polymer.

Will the project be a success? 
Well, the researchers have taken this project from DARPA as a challenge and no doubt that they have enough potential to make this device a reality as previously they have lots of experience in making this type of micro-devices and their work on Restoring Active Memory programme has been so far a brilliant run of success.LLNL also supports President Obama's Brain Research Organization through advance neural technologies.So,hope this project becomes a success and become a good news for those people who are suffering from Memory loss diseases.

Mathematics will make internet Five times faster than today!

Today i will share you the information that how a mathematical equation can make the internet communication via any electronic device be it mobile,laptop or even satellite many times faster and secure than today.The results which Aalborg University in collaboration with MIT and Caltech has achieved is phenomenal and getting attraction from the whole international technological media.The experimentation was conducted by taking the example of a random 4-minute video which by this method was downloaded five times faster and was run without any buffering compared to the old systematical way where it had buffered for 13 times when it was streamed online.So,you can make the difference that how fast it was and what could possibly it advantageous point.

This experiment has the potential to change the outcome of the future internet market.As using these mathematical equation the researcher will able to improve their own network coding traffic and the equipment manufactures experience speed would be increased by five to ten times.And this technology's most beneficial factor would be that it will speed up the internet for the whole world(each and every human) be it in mobile connections,computer connections and even the satellite connections.

How this mathematical equation is being used and what is the original method?
In the current method what happens is that the internet communication formats data into packets.Error controls ensures that signal arrives in original form but it often means that sending some of the packets several times which eventually slows down the net.Instead of sending these packets US Researchers are implementing a mathematical equation which is nothing but a special kind of network coding method that uses clever mathematics to store and send the signal in a different way.The advantage of this method is that the error which occurs along the way do not require the packets to be sent again instead the upstream and the downstream data is used to reconstruct what is missing using the given mathematical equations and solving it then and there only.

Looking at the advantageous points of the technology its no doubt that it would be integrated soon enough in the market but there are still some problems which can stop the development and implementation of this method and that are patents.US Researchers who have founded these method have also founded a software company called Steinwurf.The problem is that previously individual companies had a solid grip in patents for coding but now its a different ear.Perhaps the team has said that they also have a aim to launch this project so that it can be accessible to all as much as possible.Among other plannings they are also aiming to conduct training courses on the usage of these technology.Well,i hope they do release this technology which will really change the fate of the future internet and make it faster than ever.

Electromagnetic Principle is used to run World's Fastest trains!

Airways are no doubt the fastest way of transportation in this century and the safest too.
Compare to Airways-buses,trains,cars and motorbikes are too slow and comparatively dangerous too.But one way of transporting is developing too fast nowadays and that what we called Bullet trains in Japan and TVG in Germany.This train can also be named as Maglev train as it generally runs on the property of electromagnetic levitation and so the name "Maglev".Maglev trains have enough potential to revolutionized the transportation of 21st century like what Aeroplanes did it in the 20th century.So,in this article i will say how this Bullet or Maglev trains generally runs.

Maglev trains if very simply put into words can be said runs with the help of powerful electromagnets.This type of trains generally uses the property of electromagnetic suspensions which means that this train will float over the guideway using the general principle of magnets to replace the old steel wheel and track trains.The basic difference between a Maglev train and a Normal train is that Maglev trains do not have any engine at-least the type of engine used by Normal track trains to pull the typical train cars along the tracks.The engine that is generally used in Maglev train is inconspicuous as instead of using fossil fuels it is run on the basis of magnetic field created by the electric field by the guide walls and the track combine to propel the train.

Working:
The magnetized coils running along the wall are generally termed as Guideway which repels the large magnets on the trains undercarriage thus allowing it to levitate it between 0.39 to 3.93 inches above the guide wall so that once the train is levitated power is supplied to the guideways which creates a unique system of magnetic fields which pull and push the train along the whole long guidewalls.The electric current supplied to the guide walls continuously changes its polarity in magnetized coils due to which the magnetic field in front of the train is helping the train to pull the train forward while the magnetic field placed at the back of the train is helping the add more thrust to the front of the train.

The Maglev trains generally float over a cushion of air thus eliminating any kind of friction.Since there is no friction these trains a can reach an unprecedented ground transportation speed of 310-320 mph. An Boeing-777 runs at a speed of 562 mph so you can imagine why we are comparing Maglev Trains with Aeroplanes.At this speed it is seemed that you can travel from Paris to Rome within a time span of just two hours.

Differences between German and Japan Maglev trains:
Although both of the countries are using the same principle but the principle in running the trains have some distinct differences.In Germany they are using these Electromagnetic suspension Theory(EMS) while in Japan they are using the Electrodynamics suspension principle (EDS).The basic difference is that Japan engineers are using super-cooled superconducting electromagnets which can run even if the power supply is switched off.While in the other case the German engineers have developed a system called trans-rapid system which will run only if the power supply is switched on-otherwise not.If compared japan is using a better technology by chilling the coils at frigid temperature to make it cryogenic system.

Although the expenses of building an Maglev train is too much but once build it is very cheaper and energy saving.India has currently planned to implement the Japanese technology to implement Maglev train in Indian railways though nothing can be said off as now.But if its build then it would be great technological advancement for the both the country and the world.

After 24 years "History repeats itself for Germany"

And at-last they did it.Germany won the World cup 2014 after 24 years and they did it in quite a similar fashion as what Spain did back in 2010 WC.There was no doubt that after their performance against Brasil in the semi-final they were the favorite one to win this competition but still it was not as easy for them as they might have thought to be.Argentina gave everything in the match-nobody could deny the fact that they were better amongst the two teams but then again Football matches depends on goals and Germany found one in the late minute of the game.The match started with a great enthusiasm and the whole stadium was supporting Argentina including Brazilian's also as they wanted eagerly their neighbor to win against the team which tormented them in the semi-finals.

Within the starting few minutes Argentina were full attacking with many shots on the goal but Neuer saved it all. Neuer was very jubilant yesterday in the match and why he shouldn't be after-all he was playing WC final.The stadium shouted till their last pitch volume when Higuain scored a goal from lavezzi's pass but unfortunately it was a offside which eliminated the goal.After that Germany also created many chances but none was converted. Messi was playing at his best but it was hard for him to invade the German defense.

No goals were scored till the 90 minutes and this has been going on from the past 3 WC's that the match has went to the extra time to decide its faith.And so it has been decided these year as well when substitute Mario Gotze has scored the goal in the late 113 minutes which gave his team the world cup 2014.The goal silenced the whole stadium and the dreams of thousands of Argentinians went to thrash within a matter of seconds.

Anyways in football nothing is predictable and Germany deserved to win this world cup from the very beginning of it when started this ornament by beating Portugal 4-0 in the group stages.It was like Germany was destined to win these years world cup and no doubt they have achieved their dream.This match would have specifically disappointed players like Messi and Higuain who must have been feeling guilty of missing those golden chances in the match which could have very easily given them the world cup but they haven't taken those chances properly.Lots of expectation were there for Messi who if Argentina would have won the world cup could have been compared with idols like Maradona who have captained Argentina to win 1986 world cup.

None the less Germany lifted the most prestigious trophy in the world.For Manuel Neuer it was like double silverware as along with the World cup he also won the golden glove award.Golden boot award went to  promising Colombian youngster Rodriguez for scoring six brilliant goals in the tournament.While Golden boot award went to none other than the world's best player Lionel Messi whose performance in this world cup was best at par. Whatever happened in this world would now be a sweet memory for all of the German fans but one thing will remain as a fact that may be Germany have won the world cup but after Argentina's performance in the world cup they have surely won many people's heart.

Print yourself a 3-D Model of a Nebula-Thanks to NASA!

Well for Astrophysicists and Astronomers its quite a disappointment that they cannot get hold of the things that they discover.But now things have changed and like Zoologists and Geologists Astronomers can also get a glimpse at what they are creating and can actually hold them.Thanks to Astrophysicist Wolfgang Steffen from National Autonomous University of Mexico who with the help of NASA created a 3-D printed model of  Homunculus Nebula.He used a software called"Shape" to make this possible.

This giant cloud of light, gas and dust was discovered in the mid 1800 when binary star system called Eta Carinae located about 7500 light years away erupted.Due to its eruption it had spewed a massive amount of solar material into the universe due to which it was ranked as the 2nd most brightest start at that time.In this System one of the star hold up-to to 90 suns and can produce as much as 5 million times more energy as compared to sun while the other generally the smaller one in size could be 30 times the mass of our sun and can be million times brighter..Through the help of X-Shooter Spectrography the astronomers had to experiment around 92 slices of the system whereas before this experiment the researcher had an idea about of 5 slices only.So this was a big achievement for them.

The experiment were carried forward to find the answer of a question that whether Homunculus contain any imprint of the stars binary nature.Since previous report suggest that both the lobes were identical and symmetrical along their longer axis.But new studies shows that the collision between Eta Carinae's stars helps to mold Homunculus. It also shown that that the holes located at the end of each lobes and the absence of any molecular hydrogen emission from dust skirt visible at light near the center of the nebula.So researchers were able to prove that if the two stars of  Eta Carinae are collided then they do will have an effect of formation of the Nebula in which they are contained.

The experiment was an exciting thing not only for the scientist and astronomers but to the normal public and students as well - provided that they have a 3-D printer.Well let me tell you if you are a owner of a 3D printer then you can hold the homunculus by printing out the high resolution 3D model of the cloud-gas formation and you can also watch the collision happening and what after the collision? in front of your own eyes.All you need to do is  follow the steps given by NASA .Follow the link to download the zip file.

Brazil tasted its worst defeat while Argentina made it to the finals!

Embarrassed,Humbled,Crushed,battered,destroyed,however you want you can put it but Brasil were thoroughly humiliated by the Germans on the first semi-finals of Fifa World cup 2014.Brasil 1-7 Germany.Well,the scoreline says enough that who was the superior among these two juggernauts of these century.It was like the match between David and Goliath but it was David who took the challenge of defeating the opponent.The way Germany played versus Brasil was magnificent and spectacular.They gave everything and showed that what they are and they have shown that on the opponents ground and that too on these big occasion.This match will go down in the history of Brazilian football history as the biggest ever defeat after 1950 and it will also end Brasil's home-run winning streak.

Brasil very badly wanted to win these match as first of all they were playing in their home in front of their own fans plus they were the five times champions but i hope they could never believe that the match could end with a result of something like these.Nobody could ever believe that team like Brasil can loose with this kind of goal line margin.On the other hand Germany's performance could never be so better.Thomas mueller,Kroos,Schrrule,Khedira and none other than Mirolsav Klose who made a record by scoring most goals ever in the FIFA world cup history.All of their performance was best at par.The whole German team contributed to these historical match and they took the revenge of that 2002's 2-0 world cup final defeat in the hands of Brasil.

While on the other semi-final match it was Argentina who went to beat Netherlands on penalties to reach the finals.It was a rainy day at Bello Horizonto and after Brasil's traumatic 7-1 loss to Germany it was all down to Argentina to save some of the South American football in these world cup and quite frankly they haven't disappointed us at the end of the day.The match started well with each team having good percentage of the possession of the ball but no result came out within 120 minutes of the game.It went only to penalty shootout
to decide the match and it was Argentina who got the silver medal at the end of a very tiring day.

Both team were tactical and cautious relying on crisps midfield playing and tactical defense with very less chance to shoot at the goal.The so called game-changers struggled to make even the slightest of chances. Messi was a threat for Netherlands but he couldn't show his level best for the whole match until at the end where he scored a penalty,same goes for Robben and Van Persie.Argentina's coach Sabella said "I am very happy that we did make it to the very end but from here we have nothing to return for.I have respect for both the team and i hope the better team will grasps the world cup 2014."So,friends lets see what happens at the grand ceremony in Maracana where probably the greatest ever teams will meet in the final none other than the match we all eagerly waited for "Germany vs Argentina".

                                                                                                                                  Anuttam Chatterjee

Germany won 1-0 on a epic clash against France

Brazil 2014 world cup has been so far based on neurotic defense and liberated attacking football but at some times it has bored us as well.Exactly the same thing happened yesterday when Germany faced France.Germany made a record yesterday to be the one team who successively qualified for world cup semi-finals for four times continuously though they haven't won in any of this world cup.This is not that lavishly exciting German team and they also haven't shown that ruthless attitude of scoring goals as we all would have expected.While France was full of new and young(mostly inexperience players) and was comparatively weak in front of Germany.

Yesterday around thousands of fans were present in the famous Maracana stadium to watch this epic clash between the two giants of central European countries-Germany facing France.From the very beginning of the match Germany dominated the game.With their passing ability Germany had managed to kept the ball possession very high which also resulted to the header of mats Hummels in the 12th minute which was the first and the only goal of the match.Though Germany were keeping more possession but it didn't stop France to show their counter-attacking ability as Benzema had been able to show his talent in front of the goal but Neuer yesterday was absolutely brilliant..Through the whole match France had very little attacking position and when they did have any real chance it was Bayern Munich's Manuel Neuer who had stopped them.

Although the game didn't showed any type of ebullient mood but it did showcased the fact that this Germany team have that potential to be the very best at the world.However German coach Jaochim Low said that "South American teams are at an advantage as they are comfortable with the climate and knows how to play on this turf".No,doubt what he was intending to say and to whom he specifically indicated those words to?Of course it was Brazil whom they will face on the semi-finals.His words also brought some speculations that whether he is a little bit nervous but then again nothing can be said right now.

On the other half-disappointing manager Deschamps said that his team was unlucky as because they had created a lot of chances but due to lack of experience players and good German defense they were unable to convert those few little chances they created.France clearly had a motive for these years world cup with 8 goals in their first two opening matches but then somewhere in the middle they failed to keep up with the heat in Brazil.Anyways Germany will face the homeboys i.e Brasil in the semi-finals which would a very tough match for the central European
team

Netherlands clinched a 90 minute victory while "Fairy tale" continues for Costa Rica

Well,world cup 2014-A football world cup in which so many talents are playing,so many surprising moments,so many legendary players are playing their last world cup but the most interesting moments are that catches your eye are exactly teams like Costa Rica,Mexico and Chile have done.Well,yesterday Netherlands was playing against Mexico and what a match we have seen.

The match started with everyone hoping for the dutch to win but it was completely a different story in field than that of what we have seen in paper.Mexico was on fire from the very first minute of the game.Most of the attacking shots were coming from the central American team and it was i must say a very tough day for the dutch defense.Its not that Netherlands were not creating any chances but the way they should have played was lacking completely.Anyhow the first half went 0-0 (Lucky Netherlands) but it was not so lucky when just after starting of second half Giovanni Dos Santos shot a blister from his left foot.Mexico continues to terrorize the Netherlands defender up-to 88th minute of the match but then suddenly the veteran Sneijder snub a quick goal and a very important goal for his side.Then in the 90+1 minute robben felled down in the penalty area thus acquiring a controversial penalty for his side. Klass Jan Huntelaar very calmly took the penalty and won the match for dutch in the dying minutes.The whole stadium broke into tears after seeing Mexico's performance(after all they came out to be the better team out of the two).

One question remains in our mind that whether that penalty was really a penalty,Did Robben dived?Anyways whatever it is all we know that Netherlands is in the next round and Mexico isn't and as we say in football scores matters the most and so it is.In the other match it was Costa Rica facing the Greece..Another team which has surprised fans and footballers all over the world with their amazing run in this World cup.No body thought that they could even qualified the group stages but by beating Uruguay and Italy and drawing their match with England they stood top in the group of death.

Now it was their first match ever in the round of sixteen and it was against Greece.From the very first minute that had to play the game like a battle of attrition and Bryan Ruiz and Campbell were playing at their peak and then Bryan did scored in the 52nd minute.It was not all over for the 2004 Euro cup Winners Greece as they always keep enough potential to shut a team down.And exactly that happened when they scored the equalizing goal in the 90th minute.It was as if a heart breaking moments for the Costa Ricans players as they were almost through to the next round but now they had to play another 30 mins to achieve their dream in the extra 30 minutes and it was no doubt that Greece was the better team but finally the match went to penalty shootout where Michael Umana scored the final penalty to win the match 5-3 against Greece and went to the quarter finals where probably they will meet Netherlands.

So,hope that the best team win is the quarter finals!

Neuro-Bridge Technology helps a paralyzed limb to move!

For the first time ever a paralyzed man can move his limbs and fingers with his own thoughts by the help of a new device.The technology is known is Neuro bridge which is a electrically operated neural bypass for spinal cord injuries that reconnects the brain direct to the muscles thus helping the quadriplegic person to move his paralyzed limbs voluntarily.The idea was joint generated by the Ohio state University Wexner medical center and Battelle.


The technology is using advanced algorithm that learn and reads the signal from the brain and high definition muscle stimulation sleeve translate the neural impulses from the brain and transmit new signals that help to control the paralyzed limb.What is actually happening is that the new brain signals is bypassing the spinal cord injuries and transmitting new signals to move the paralyzed limbs.So the name is given as Neuro-Bridge.

The technology was in the making from a very long time as it took the researcher from The Ohio State University a decade to develop the Algorithm,software and the stimulation sleeves.The scientist first recorded the neural impulses through the electrode implanted in the paralyzed patient's brain.They then use the data to illustrate the device's effect on the person's brain and proved the concept.Some clinical trials were taken so that there can be enough feasibility and assurance that the Neuro-bridge technology can be applied on the patients.And the records were quite satisfying.

Ian Burkhart was the first person to take the trial and the operation was successful.First a small chip of size of an pea was implanted on Ian's brain.The chip interprets the brain signals and send them to the computer where it is re coded and then transferred to the high definition stimulation sleeve  that execute the proper muscles to execute the movement of his desired muscles.Within tenth of seconds Burkhart thoughts are being executed.

Along with this technology the scientist have also developed another theory that is neurostimulation technology where it is in the form of  a wearable sleeve that activates the movements of a single finger or allows precision to move small muscle movements in the arm.The scientists are also developing a software that helps to form a virtual spinal cord for the co-ordination of dynamic hand and wrist movement.

It was not at all easy for the scientist as the experiment was performed for a very long time as the scientist had to monetize the correct sequence of electrode which could stimulate Burkhart to move his hand in his desired direction.The patient also had to work for long time as wearing the stimulation sleeve he had to made his atrophied muscle strong so that they could be strong enough to response to the electric signals transmitted by the brain.The researchers are currently working on human machine interface and interactions and how they can be utilize in the future of biological fields.

I also think this is a great technology as well as a great news for all those who are suffering from Brain and spinal cord deformities and i hope this technology continues to increase and help to develop new kind of science.

Brasil were almost out of the WC14!

What a match yesterday!Brazil vs Chile in the round of sixteen. Brazil went to the match thinking that it would be an easy prey for them but the match went somewhat different when Chile replied with so much expressions in the match.Not even in 120 mins Brazil were able to defeat Chile but it took a penalty shootout to decide the match for the Homeboys finally.The crowd in the stadium yesterday was worthwhile to see..it seemed as if that the whole Brasil was present there.But it was not all joyous moments for them for the whole match,it was only after the 120 mins that they could enjoy because Chile's performance yesterday was spell-bounding.Lets see what happened in the match.

Brazil was full of excitement,passionate from the beginning of the match and why they should not be as they were playing in front of their thousands supporters and that too in their home.They started the game well with frequently creating attacking positions with few on target shots as well.The whole stadium went to roaring when David Luiz scored the first goal for Brasil as well as his first career goal for the team-it was a good corner kick from Neymar when the goal was executed.Though Brasil's dream run didn't last for long as the man who Brasil feared the most Alexis Sanchez scored the equaliser by scoring a beautiful goal down the goal post.The match went 1-1 into the half time.

In the second half it was like a war going on between the two south American team.Both the team were playing their best and were at their peak.Shots were coming out,tackles were made and tough decision were also taken by referees plus the electric environment created by the presence of the fans in the stadium.But somewhere in around 70 mins Brasil started taking more attacking position and they were playing full counter attacking but somehow or i must praise Chile's Goalkeeper Bravo who had saved each and every shot so brilliantly that it was as if he was a goal stopping machine.Just two minutes left in the game when Pinnila with a great run shot the ball...for a second the whole stadiums got silenced heart beat stopped but it was relieved when the ball hits the post and got rebound.

 

The match went into the extra time but both the team were unable to produce goals though exciting moments came when the ball was near the goal posts for both the team but everybody was eager for a penalty shootout and at last it came to penalty shootout only to decide the match.Lots of agonising moment,Players were nervous ,managers were shivering,crowd were praying when david luiz took the first penalty shot and it was taken calmly into the goal.There was a relief.After that it was Julius Caesar who saved two great penalty for his team that decided the match though hulk's and marcelo's miss also was a point of worrying at the dying minutes even but when Chile's jara hit the ball into the bar it was all over for chile and Brasil went to the quarter final of 2014 world cup.

The stadium was full of tears,tears of happiness of the brazil fans-tears of anguish form chile's fans but the only question which is eating our brain out is that can brazil recover from this experience quickly enough?

Water is the future of making better Batteries.

The future of the batteries is here.Since from the early ages batteries are a very  important part of our day to day life.A day would not last in our lives without the application of batteries.If you are still wandering that how without batteries you can't spend your day then let me give you some hint.Think!can you in this era sustain without using your Smartphones or Laptops?or can you reach a far away destination without your cars?-for watching television we need a remote control to change the channels.So,all these things are done or executed with the help of a battery right?

Currently the most commonly used batteries are Lithium ion batteries which are rechargeable and are generally used in your cell phones and Laptops and your tablet computers.Lithium ion batteries are also used in electric and hybrid vehicles but due its high cost lithium ion batteries usage in a mass public is hindered.So,scientists are coming up with an idea that would help to manufacture the battery both with less expensive and more environmental friendly.This idea is nothing but water.

Batteries generally generate electricity when the electricity passes through electrodes of the batteries that is positive cathode and negative anode.Generally the cost of the cathode is more than 70% of the other materials which is used to make lithium ion batteries.The other most important things which helps the battery is nothing but the solvent(N-Methylpyrrolidone or in short NMP) which is toxic material and generally releases flammable gases.Making batteries with this solvent also requires expensive explosion-proof processing equipments and costly solvent recovery solutions.Plus this solvent is not at all environmental friendly.

So,what the scientist are thinking is nothing but to replace this NMP solvent with water.But its not so easy as i am saying to you right now.Actually the NMP solvent makes the electrodes a good current collector substance which means makes its good enough to gather electrical charges from the cathode.But if water is being used then its slurries may not be able to smooth the electrode so that it can coat the current collector.So it requires extensive knowledge from the field of both science and engineering to perform this experiment.

The scientist so far has tried different tricks out of which the most prominent is to treat the current collector with electrified plasma which can alter the surface of the elctrode so that it can make water based slurries coat better.Using this method the price of lithium ion batteries can reduced almost one-eight of its actual price right now.Plus we can get a much more greener and environment benign battery device which will give much more better performances.The process is still in the lab and not been delivered in the market yet.Soon,it will be.

So the main thing in this whole process was nothing but Replacing NMP with Water.

Bionic eye-Lets Blind man see again!

Technology!What clicks your mind when you heard this term?Technology is nothing but a building standing on a base called science.And with the days passing by-technology is also advancing beyond the limit that a man can ever see and today i will say you about a technology or a technological device known as Argus 2 or The Bionic eye.What if i tell you that if you are blind then you will not be for long enough.Yes,this small spectacle like device called Argus 2 will help a blind man see again.Let me relate this fact with a real life story so that it can be more clear for you.

Roger Pontz a US Resident lost his eyesight completely at the age of 40 when all the surgery failed to improve his eyesight.He was suffering from a disease called retinitis pigmentosa.Roger and his family lost all their hope but then one day Roger heard that a device name Argus 2 is on experimentation.He was stunned to hear what the device could do.He was interviewed in which he said "At that time it was all experiment so nothing i was sure off but i was very excited as there was hope that i can regain some of my eyesight so i had a belief that this experiment would someday turn into success and so it has". Today Roger can see only through the help of Bionic eye.

So How this bionic eye works?Bionic eye is a type of device which has small camera mounted on it to processes images.A eraser like prosthesis is surgically implanted on the retina of the patient and the information is transferred from the camera wirelessly to the electrodes present in the artificial retina  where it is converted into electrical pulses.Any remaining tissues that hasn't been damaged by the eye disease are stimulated by the electrical pulses generated by the artificial retina to form light pattern in the brain.Though the person cannot see all the things clearly but enough sight is generated so that he can see where he is standing or like who is standing in front of him.

It came to USA only in 2014 after the approval from the food and drug administration of US government.But the technology has already been released three years before in Europe.The American society of ophthalmology said that though this type of surgery brings some complication and so it isn't available for mass public though it is a great news for all those who are blind.Its a great technology and despite it can give you some vague pictures but still its better than being completely blind.

With the success stories of patient like Pontz there is still chance that this technology advances and bionic eye can upgrade itself.Researcher are currently working on it and one day i hope it do gets updated and let a person see

clearly.That would be an amazing Technology.
