Climate Chage

The Great Lakes have been a bastion of stability, with water hovering at about the same level for as long as anyone can remember. But, according to a report in Discovery News, a new study shows that climate change once pushed lake levels far below where they are now. That opens up the possibility that future climate change might do the same thing. More than 33 million people depend on the Great Lakes for water, hydropower and work in industries ranging from shipping to recreation. During the past event, about 8,500 years ago, water ceased to flow between the lakes. Today, going from interconnected bodies of water to isolated basins could be catastrophic.

For decades, scientists have been working to reconstruct the aqueous history of the Great Lakes. Those reconstructions showed that, for thousands of years, lake levels have only varied by a couple of meters up or down, mostly due to the advance and retreat of glaciers, which alternately trap and release water. As they move, glaciers also cause land underneath them to rise and fall slightly.

Blush

Why do we blush? When our cheeks go red with embarrassment, shame, or even pleasure, people say we are blushing!

That is because, tiny blood vessels (capillaries) under the skin open wide to let lots of blood run through. Blushing is one of the ways the body has for keeping the blood, it sends to the brain at the correct temperature. Now, comment on your blushing experience!

Indians

The second test match between India and Australia was a perfect match for India right from the toss. MS Dhoni, the inspirational Indian captain had no second thoughts after winning the toss to bat first. India batted first aggressively right from the first over to put pressure on Australia. It was one of those matches to be remembered for Tendulkar who became highest run scorer in tests beating previous record holder Brian Lara. Ganguly who announced his retirement after the series scored a timely century, in the process scoring 7000 runs in the test cricket. MS Dhoni who showed his presence felt both as a player and more importantly as an agressive captain was rightly awarded the “MAN OF THE MATCH”.

The next match now is eagerly awaited where Australia would be looking to level the serious and on the other hand India would want to clinch the series before going into the final test match. For us fans, its going to be another high level of entertainment watching these two top teams in world cricket battle it out.
