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".

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.
