Theories about origin of life

Its_gora

Electric Spark

Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form.

Community Clay

The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now.

Deep Sea-Vents

The Deep Sea-Vent theory suggests that life may have begun at submarine hydrothermal vents, spewing key hydrogen rich molecules. Their rocky nooks could then have concentrated these molecules together and provided mineral crystals for critical reactions. Even now, these vents, rich in chemical and thermal energy, sustain vibrant ecosystems.



Panspermia

Perhaps life did not begin on Earth at all, but was brought here from elsewhere in space, a notion known as panspermia. For instance, rocks regularly get blasted off Mars by cosmic impacts, and a number of Martian meteorites have been found on Earth that some researchers have controversially suggested brought microbes over here, potentially making us all Martians originally. Other scientists have even suggested that life might have hitchhiked on comets from other star systems. However, even if this concept were true, the question of how life began on Earth would then only change to how life began elsewhere in space.

Planet with two Suns

Its_gora

A giant and frigid planet that enjoys double sunsets as it circles two stars has been spotted in the northern skies.

Astronomers said the planet, named Kepler-16b, marked the first unambiguous discovery of a world in orbit around two stars – an oddity made famous by the planet Tatooine in Star Wars.

The planet, which lies about 200 light years from Earth and has a similar mass to Saturn, was observed by Nasa's Kepler spacecraft as it passed in front of its twin suns, causing light from the stars to dim.

The unusual arrangement means that an observer on the planet's surface, where temperatures range from -70C to -100C, would see two small suns rise and set together, and on occasion appear as one as they passed in front of each other.

The amazing baobab (Adansonia) or monkey bread tree can grow up to nearly 100 feet (30 m) tall and 35 feet (11 m) wide. Their swollen trunks are actually water storage – the baobab tree can store as much as 31,700 gallon (120,000) of water to endure harsh drought conditions.

Baobab trees are native to Madagascar (it’s the country’s national tree!), mainland Africa, and Australia. All parts of this amazing tree are useful. The young leaves are used as condiments and medicines. The large gourd-like, woody fruit contains a tasty pulp. Also called “monkey bread”, it is rich in vitamin C. The bark produces a strong fibre which is locally used for making rope and cloth. 

Mature trees are often hollow and provide living space for humans and animals. The baobab figures as the Tree of life in the film Lion King.

For most of the year, the tree is leafless and looks like it has its roots sticking up in the air. According to the legend, the devil uprooted it, thrust its branches into the earth, and left its roots in the air. There are also numerous superstitions regarding powers of the tree.

Wood Becomes Stone

Its_gora
Arizona's Petrified Forest is not a forest at all. It is a hauntingly beautiful landscape filled with magnificent specimens of petrified wood. Petrified wood is a wood that has turned into stone. How did this happen? Millions of years ago, the forests covering Northern arizona were buried under a sea of mud, sand, volcanic ash, and and the pressure over a period of time turned the wood into stone, to create a forest of  Stone Trees!!

The Cyanide Eater

Its_gora
 The Golden Bamboo Lemur of Madagascar, can eat cyanide, an extremely poisonous chemical , without an ill effect. there is a type of bamboo, which contains cyanide in its shoots, with a quantity of twelve times the lethal dose for humans. The lemur has learnt that eating the iron rich soil in its home range, it can neutralize the poison!!!!!!
Only Humans are not quick Learners...

A remarkable fish story

Its_gora
One day  Mr. Walter Ker, a New Zelander threw a mussel,which is a type of shell fish into sea. A fish known as a snapper grabbed it and swam away. Soon this became a regular practice, and Mr. ker would feed the snapper every day. Before long, other snappers joined the first as they learned that free food was being handed out each day at the same time, at the same spot. What is more, they would even allow Mr. ker to stroke their backs and lift them out of the water!!!!!!

Isn't it remarkable?

Highest Number of Passengers in an Aeroplane

Its_gora
That the record for most number of passengers on an aeroplane was created way back in 1991, when 1,120 people boarded a Boeing 747 in Addis Ababa, Ethiopia??
That was during operation Solomon, when  Ethiopian Jews were evacuated to Israel..
Records show that 1,087 passengers were registered..

The flight was supposed to carry 760 passengers, but they were so thin that more could be squeezed in; while many children hide in their mother's robes..
With two babies being born during the flight; 1,122 people stepped off the plane!!!!!!!!!!!!!!
What a record!! Ha, Ha!
