Land animals are not the only ones being affected by the loss of habitat and climate change. The issues are taking their toll on birds too. Experts estimate that since the 1500's, over 190 bird species have become extinct. Of these, at least 12 were endemic to North America.

Tornados in the Midwestern and Southern United States have always been a troubling yet fascinating phenomenon - just think of Dorothy's whirlwind adventure in the Wizard of Oz! Occurring predominantly in the area east of the Rocky Mountains dubbed 'Tornado Alley', they form during severe thunderstorms called supercells that occur when cold dry polar air comes in contact with warm moist tropical air.
In early July, shepherds walking across the Tunisian desert, stumbled upon an unusual sight - a beautiful blue lake that had mysteriously appeared in the midst of the parched land. While nobody knows for sure how the 60-foot deep stretch of water that spans over two acres was formed, there are a few theories.
Each year around this time, stargazers anxiously await nature's finest fireworks show - the Perseid meteors. The 'fireball' champions of all annual meteor showers have already been streaming through our skies at the rate of about a dozen an hour, for the last few weeks. However, things will really heat up from early August 11th to the 13th, when between ninety to a hundred meteors will come zooming across the skies, making them easy to spot, even with the naked eye.

Mention koalas and the image that comes to mind is that of a cuddly animal snoozing, whilst clinging on to a tree trunk for dear life - and rightfully so, given that the animals sleep for up to 20 hours a day! However, while the fact that their sedentary lifestyle is caused by their unusually small brains and the limited nutritional content of the eucalyptus leaves they consume is well-known, what was never questioned was their penchant for tree trunks. Turns out that the smart koalas have figured out that staying close to trees is the best way to beat the heat, during the hot Australian summers.
The fact that the Japanese love robots is well-known. The nation of 127 million people currently employs over a quarter million robots workers, more than any other country in the world, and the number is expected to quadruple in the next 15 years. So far, most of the robots have been built for the industrial sector and therefore bear no resemblance to humans. But if some scientists have their way, the days of androids - robots that look and act like humans, are not too far away.
For people that live in the Northern Hemisphere, Saturday, June 21st, will appear to be one of those glorious days when the sun has forgotten to set and depending on where they live, that may actually be true.
