How to always buy only the best merchandice online.

If you are reading this, chances are you have already or are planning to buy something on the internet. Mostly everyone knows giant sites like amazon or ebay, but they only have limited variety in price. Buying from store websites can be a bit trickier, because you have to go through them one by one in order to find the best prices. If you are looking for the lowest prices, I suggest you try finding lowest prices via Shopwiki.com .

Other websites that list items for purchase might give priority to companies who paid a certain fee to get the best spots. With shopwiki, you can rest assured that it will find you the lowest prices no matter what. This website uses a system simlar to google's. They use "crawlers", which check every website and update the system with lowest prices. This also means that you can find almost every item offered by any shop for sale. And as if that wasn't enough, everything's presented in a nice, yet sometimes hard to understand, style.

At the homepage you get a nice list of categories. For this example, let's see babies and toddlers, because there are more young parents in the world now than ever. This opens yet another page, full of quite useful information. The so-called "guides" actually describe why and when should you buy the specific item. Pressing the hyperlinks will take you to the merchandise page with price and availability. Toys and games, might also be of interest to parents. You can find all sorts of games here, from video games to retro toys. If you want your child to enjoy what you might have experienced during your childhood, i would recommend looking at that.

To sum up, this is an essential site for modern internet. I mean, you should not spend hours upon hours in order to save some money. With shopwiki, lowest prices can be found in minutes, saving you a headache and some money

Inexpensive and reliable glasses.

You might have heard of Zenni Optical. Even i have already wrote a post or two about them. Even though, luckily, I don't need glasses myself. Yet. But if you ever had a shadow of doubt about Zenni optical, if you have ever wondered whether it's legitimate, what I'm about to present to you will erase all doubts. The New York Times team published an article about vision correction. Incidentally, Zenni Optical is mentioned as one of the recommended frame suppliers. If you're serious about buying glasses, you shouldn't miss out on this article.

Labeled "Seeing straight without breaking the bank" really describes the best thing about Zenni Optical - they offer quality merchandise at low prices. An appointment at the oculist, custom frames and lenses can add up to several hundreds of dollars. But you can have almost the same effect by simply buying a pair of inexpensive eyeglasses for those rare occasions you might need them, because let's face it - nobody wants to constantly wear glasses.



Take these glasses, for example. Nice and stylish, aren't they? And these can be yours just for 8 US dollars. Note that before ordering, you should get checked by an eye doctor just to know what lenses do you need. Besides, they ship internationally.

The International Polar Year comes to an end.

The International Polar Year, despite being called a year, actually was set to last from march 2007 to march 2009. Today being 26th of February, the IPY is coming to an end. The major studies took two years, because of the need to cover both, the north and south poles. I recommend you read the press article at the IPY website and look around there in general if you're interested in the state of Earth's poles. But in short, it's pretty bad.

The global warming has taken it's toll from the arctic and antarctic regions. It has been reported that ice coverages have reached all-time lows in the recent years. The fresh water that enters the sea when ice melts will have an impact on wildlife and humans alike. Over the two years, 160 science projects have been performed using a total of 1.2 billion US dollars , assembled internationally. Here are the key discoveries:

• The melting ice from both Greenland and Antarctic ice sheets is contributing greatly to sea level rise. In addition, the rate in which ice melts was found out to be higher that anyone expected and is still increasing.

• The arctic sheet has also suffered. Ice, that is around the arctic circle all year-round, has apparently reached a minimum over the 30 year period of observation. There was also a lot more drifting ice than researchers had previously thought. Global warming has changed the vegetation in the arctic too.

• With the melting of antarctic ice, and much more fresh water entering the Southern ocean, it's circulation could be affected, resulting in climate change.

• It has been known that the frozen land of Siberia has much carbon-based material in it. If the temperatures rise, which they do, millions of cubic meter of methane will be released into the atmosphere, strengthening the effects of global warming.

• The IPY studies have also uncovered interesting information about atmospheric issues. For instance, North Atlantic storms bring a lot of heat and moisture to the northern polar region.
  

Just under a 100 years ago, people have only reached the poles for the first time and now, we have to make sure they don't disappear off the map. Luckily there are large-scale projects like the IPY, which determine the problem, it's cause and most likely find a solution. But what i like most about this is cooperation. Each day we hear news about war, political unrest and various other forms of hostility and distrust. And now, when our planet is at stake, people put aside their differences and realize that we are all united by the piece of rock we're stuck on. And we have to protect it.

Our oceans are not soaking up as much CO2 as we'd like to.

The sea has always captured the imagination of all people. Neither has it shown mercy to the brave people that dared to traverse it and claimed many lives. Luckily, our oceans also claim a lot of carbon dioxide, helping keep the air we breathe fresh. Not as efficiently as we'd like, though.



I assume we all know by now that too much carbon dioxide is hovering in our atmosphere, and the pollution levels continue to grow. But, man has to understand, that not everything is within his power. The various flora of our world soak up the carbon dioxide and produce oxygen. This process is know as photosynthesis. But did you know that most of the carbon dioxide is absorbed by oceans? Firstly, it is used by plankton for photosynthesis, and secondly, it simply dissolves in water as most gases should. Carbon dioxide molecules are heavier than water, so the gas slowly makes its way down to the depths. Add the dead fish and plankton to that, incredible pressure from the water above, and after millions of years of anaerobic decomposition, and you'll get oil!

The main point is that the deep seas are CO2-heavy. But thanks to the already undergoing climate changes, the winds above seas increase, thus causing considerable water mixture in the seas. That means that deep water comes up, bringing all the carbon dioxide with it. Although it will not exactly make it's way back to the atmosphere, the surface waters mix with the deep ones, thus the surface waters will have more carbon dioxide in them and less from the atmosphere can dissolve in them. This phenomenon actually decreased the absorbing capability of 0.5 Gigatonnes per year, to almost 10 times less, 0.05 Gt/y. (Research was conducted in the Southern ocean.)

The study has been conducted over a 10 year period, so the numbers really shouldn't lie. As you see, the ammount of carbon dioxide people produce is not as big as there is already circulating in nature, but that doesn't mean that we should cut down on emissions. After all, it may have been human pollution that caused the weather change. One event leads to another, so let's wait and see.

Telescope to scour the skies for earth-like planets.

The Kepler mission

Have you ever asked yourself whether there is life in the universe? You've most probably had. Or perhaps we are alone in the vastness of space? Well believe me, you're not the only one pondering about this. While we, simple citizens, are restricted to simply thinking, our researchers put millions of dollars into space research. One of the latest NASA's creations is the Kepler telescope.

Kepler's main mission is to identify planets that would seem to be habitable. Which means planets, that have a sign of water on them. And they should be of similar proximity to their star as Earth to Sun. These are the two main points, as the correct position may indicate a climate, also similar to Earth's. Which, in turn, could very well mean extraterrestrial life.

But Kepler will not be looking for life. Instead, the telescope will determine the frequency of Earth-like planets in space. Since no definite data can be collected at this distance, scientists will have to use simple logic in order to determine whether there is life elsewhere. If there are many Earth-like planets, the chances of life are higher, and the other way around.

And how exactly does the Kepler telescope work? As you know, the distances are far too great to actually see something particular. Well, the telescope is designed to notice changes of light, dimming, to be more exact. As the planets move around their star, they are bound to get between it and the telescope. Similarly to a solar eclipse. Even if we wouldn't know of the moon, when it would get in between and block all light, we would notice it. So when this eclipse happens in the observed solar system, Kepler will immediately notice it and determine the distance between the star and the planet.

However, the Kepler telescope will need to observe these planets for years to confirm their presence. The mission is set for 3.5 years. For more information and a launch date, visit the NASA Kepler homepage http://kepler.nasa.gov/. Space exploration continues!
