Facts About Human Body - Total 15 - Must Read !!!!

1. The stomach’s digestive acids are strong enough to dissolve zinc. Fortunately for us, the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.

2. The lungs contain over 300,000 million capillaries (tiny blood vessels). If they were laid end to end, they would stretch 2400km (1500 miles).

3. A mans testicles manufacture 10 million new sperm cells each day – enough that he could repopulate the entire planet in only 6 months!

4. Human bone is as strong as granite in supporting weight. A block of bone the size of a matchbox can support 9 tonnes – that is four times as much as concrete can support.

5. Each finger and toenail takes six months to grow from base to tip.

6. The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft). The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin.

7. When you sleep, you grow by about 8mm (0.3in). The next day you shrink back to your former height. The reason is that your cartilage discs are squeezed like sponges by the force of gravity when you stand or sit.

The Door To Hell

In the darkness of night, flames dance and lick the air, casting an ominous glow that can be seen from miles around in the desert of Turkmenistan. The source of all this light and heat is a massive crater, in which blazes an unceasing inferno, dubbed by locals the "Door to Hell."

It is situated near the small town of Darvaz. The story of this place lasts already for 35 years. Once the geologists were drilling for gas. Then suddenly during the drilling they have found an underground cavern, it was so big that all the drilling site with all the equipment and camps got deep deep under the ground. None dared to go down there because the cavern was filled with gas. So they ignited it so that no poisonous gas could come out of the hole, and since then, it’s burning, already for 35 years without any pause. Nobody knows how many tons of excellent gas has been burned for all those years but it just seems to be infinite there.

It's been up to storytellers to maintain the explanation for the "Door to Hell." But fortunately for the skeptical who may want to see it for themselves, the flaming crater continues to burn today--and shows no signs of dying down anytime soon.

New Suckermouth Armored Catfish

A new species of suckermouth armored catfish (pictured) has been found in Ecuador, a new study says.
DePaul University scientist Windsor Aguirre found five specimens of the odd-looking fish in 2008 in the Santa Rosa River (map) and sent them to Alabama's Auburn University for identification.
"When we first realized it was new, it wasn't particularly surprising—this family [of catfish] increases in number every year," said study leader Milton Tan, a Ph.D. student in biology at Auburn.

Instead, what interested Tan and colleagues is that the 2.8-inch-long (7-centimeter-long) species—unlike its relatives—lacks armored plates on the sides of its head.

The lack of head plates suggests the species is a "missing link" between other Cordylancistrus species and the related genus Chaetostoma, which has an unplated snout, Tan said.

The arrangement makes the new species "a really unusual fish," said Tan, who named the animal Cordylancistrus santarosensis after its home river.

Space Pictures This Week: Cosmic Flower

Spring flowers are blooming—even in space. This recently released picture shows NGC 7023, also called the Iris nebula for its floral appearance, as seen from Kitt Peak National Observatory in Arizona.

The cosmic flower is actually what's known as a reflection nebula. The interstellar cloud of dust and gas glows not because its material is being heated, but because it's reflecting light from nearby stars.
For instance, the bright glow in the middle of the nebula comes from a hot, massive star that gives off blue light, which then gets scattered by dust, lending the nebula its distinctive color.
