Sleep's memory role discovered.

The mechanism by which a good night's sleep improves learning and memory has been discovered by scientists.

The team in China and the US used advanced microscopy to witness new connections between brain cells - synapses - forming during sleep.

Their study, published in the journal Science, showed even intense training could not make up for lost sleep.

Experts said it was an elegant and significant study, which uncovered the mechanisms of memory.

It is well known that sleep plays an important role in memory and learning. But what actually happens inside the brain has been a source of considerable debate.

Researchers at New York University School of Medicine and Peking University Shenzhen Graduate School trained mice in a new skill - walking on top of a rotating rod.

They then looked inside the living brain with a microscope to see what happened when the animals were either sleeping or sleep deprived.

Their study showed that sleeping mice formed significantly more new connections between neurons - they were learning more.

And by disrupting specific phases of sleep, the research group showed deep or slow-wave sleep was necessary for memory formation.

During this stage, the brain was "replaying" the activity from earlier in the day.

Prof Wen-Biao Gan, from New York University, told the BBC: "Finding out sleep promotes new connections between neurons is new, nobody knew this before.

"We thought sleep helped, but it could have been other causes, and we show it really helps to make connections and that in sleep the brain is not quiet, it is replaying what happened during the day and it seems quite important for making the connections."

MAGNIFICENCE OF MOTHER

 Read each word slowly- digest it-you will feel good!!!!!!!

Mother  MOTHER  This is a truly BEAUTIFUL piece.  Please read this at a slow pace, Do not hurry.....this is a treasure...  The young mother set her foot on the path of life.  'Is this the long way?' she asked.  And the guide said: 'Yes, and the way is hard  And you will be old before  you reach the end of it..  But the end will be better than the beginning.'  But the young mother was happy, and she would not believe that anything could be better than these years.  So she played with her children, and gathered flowers for them along the way,  And bathed them in the clear streams; and the sun shone on them, and the young Mother cried,  'Nothing will ever be lovelier than this.'  Then the night came, and the storm, and the path was dark, and the children shook with fear and cold,  And the mother drew them close and covered them with her mantle, and the children said, 'Mother, we are not afraid,  For you are near, and no harm can come.'  And the morning came, and there was a hill ahead, and the children climbed and grew weary, and the mother was weary. But at all times she said to the children, 'A little patience and we are there.' So the children climbed,  And when they reached the top they said, 'Mother, we would not have done it without you.'  And the mother, when she lay down at night looked up at the stars and said, 'This is a better day than the last,  For my children have learned fortitude in the face of hardness.  Yesterday I gave them courage.  Today, I've given them strength.'  And the next day came strange clouds which darkened the earth, clouds of war and hate and evil,  And the children groped and stumbled, and the mother said:  ' Look up. Lift your eyes to the light.'  And the children looked and saw  above the clouds an everlasting glory, and it guided them beyond the darkness.  And that night the Mother said, 'This is the best day of all, for I have shown my children God.'  And the days went on, and the weeks and the months and the years, and the mother grew old and she was little and bent.  But her children were tall and strong, and walked with courage. And when the way was rough, they lifted her, for she was as light as a feather; and at last they came to a hill, And beyond they could see a shining road and golden gates flung wide. And mother said, 'I have reached the end of my journey.. And now I know the end is better than the beginning, For my children can walk alone, and their children after them.'  And the children said, 'You will always walk with us, Mother, even when you have gone through the gates.' And they stood and watched her as she went on alone, and the gates closed after her. And they said: 'We cannot see her but she is with us still. A Mother like ours is more than a memory. She is a living presence.......'  Your Mother is always with you.... She's the whisper of the leaves as you walk down the street; she's the smell of bleach in your freshly laundered socks; she's the cool hand on your brow When you're not well. Your Mother lives inside your laughter. And she's crystallized in every tear drop. She's the place you came from, your first home; and she's the map you follow with every step you take. She's your first love and your first heartbreak, and nothing on earth can separate you.  Not time, not space... Not even death! PASS THIS ON TO ALL THE MOTHERS CHILDREN YOU KNOW. MAY WE NEVER TAKE OUR MOTHERS FOR GRANTED... May Your Day Be Blessed My Friends

Woman goes back to work after 30 years

The shortest video you've ever seen so pay attention...   A woman goes back to work after thirty years.   Watch carefully, the video is only 5 seconds long, but, you'll get it.   If you're younger than 40 years old, you probably won't understand it.     www.youtube.com/embed/qteu4ld_SCE?rel=0" frameborder="0" allowfullscreen>

Cricket, Sauce for the Goose.

Forwarding.

Cricket.

Butler and partners  were stealing runs.

Law should adjust to make such a run no run.

Mahela in the post match interview had said that the duo of Butler and Bopara had taken 22 twos - obviously some assisted by early take off.

At the 4^th ODI vs England, Senanayake bowling warned Buttler not to leave the crease till the ball was bowled. Buttler didn’t care, and soon enough according to rules, Senanayake ran him out. That is that.

Seems Senanayake is being queried about his bowling action too as happened to Murali.

To me, most of the fast bowlers around, if not all seem to be throwing with gay abandon-  as seen on TV. Fasties are the ones to  watch.

Anyhow Sri Lanka won convincingly.

Sri Lanka winning a match or a series is no longer a 7 day wonder.

Jayawewa!

So, the England players and supporters, led by their captain, Alastair Cook, are bellyaching and whingeing about Senanayake running out Buttler at the non-striker’s end. Naturally, the crowd too joined in, and at the end of the game Cook appeared to say some nasty things to Matthews.
The bottom line is, who began this illegitimate incident that forced Senanayake’s hand? In other words, if Buttler did not provoke Senanayake by attempting to take a foul start there would not have been any incident. ICC playing regulation, amended in 2011, and applicable to this series states: “the bowler is permitted, before releasing the ball and provided he has not completed his usual delivery swing, to attempt to run out the non-striker.” 
As teen-aged cricketers at school our (unpaid) coaches used to clearly advise us, that while being at the non-striker’s end, to watch the bowler’s arm and move only after the bowler has released the ball. Seems Cook and Buttler have not been advised on this matter despite reaching international levels. A very sad state of affairs when one considers the captain of the country that gave this game to the world is in the dark. Read the rest of this entry »

Sri Lankan cricketers and SLC stand firm and remain focused

June 4, 2014

Andrew Fernando in ESPNcricinfo where the title reads “Emboldened Sri Lanka keep their cool”
As the Edgbaston crowd’s displeasure eddied around the ground late in England’s innings, Sri Lanka were still, at the centre of the whirlpool. Spectators had been incensed by Sachithra Senanayake‘s run out of Jos Buttler – a Mankad which, upon the umpire’s inquiry, Angelo Mathews did not hesitate to uphold. The England innings was already creaking at 199 for 7, but as the boos rang around the ground, Sri Lanka did not delay delivering the final blows. With 220 to chase, this would be their game to lose.

It was a brief passage of play, but one which illustrated an unwavering focus that has become a theme of this Sri Lanka team’s cricket, particularly in 2014. They had had one horror day at Sharjah in January, but quickly shed the trauma of that defeat to trounce Bangladesh across all formats. An unbeaten Asia Cup campaign came as the annual contracts tussle with the board began to bubble up. That saga erupted before the World T20, which was won with contracts unsigned, and administrators engaged in disputes with senior players. Mahela Jayawardene, the man who was most visibly shaken by the heated exchanges with SLC, was the team’s lead scorer in that campaign.

Senanayake’s mankading of Buttler clarified and defended by British reporters

June 4, 2014

George Dobell: “Senanayake catches Buttler dozing” ….  http://www.espncricinfo.com/england-v-sri-lanka-2014/content/story/750041.html[/

 Umpire Gough gives Buttler out

There was little doubt what the Birmingham crowd thought to the run-out of Jos Buttler. Boos rang out around Edgbaston every time Sachithra Senanayake touched the ball following his decision to end Buttler’s innings. Already utilising an action that some in England – a conservative country in cricketing terms – believe to be dubious, Senanayake will now forever be cast in the role of villain after running out the home side’s golden boy in a rare instance of ‘Mankading’ in the international game.

Buttler, the non-striking batsman, had backed up too far. He was out of his crease. Senanayake, the bowler, had warned him in the previous over. He warned him, clearly and in sight of the umpires, that if Buttler continued to back up out of his crease, he would remove the bails and complete the run out. Read the rest of this entry »
