Ø Continental drift: the phenomenon of continental drift is continuing till today the continents of South America and Africa are moving apart at an average of 5.7cm/year because the sea floor is spreading along the mid atlantic Ridge. This is comparable to the growth of our fingemail.

Ø Determination of Miller: Stanley Lioyd Miller when first narrated his idea of the experiment to his professor Harold Urey, he discouraged it “Oparin’s theory is wrong the professor said Miller replied Give me 6 month and then his theory was proved in only 2 months and 47 days.

Fate of Sun : The sun like other stars was born as an interstellar cloud of dirt and gas. In about 5 million years the hydrogen in the centre of the sun will start to run out. The helium would get squeezed resulting in the formation of ezpansion. The helium will get hot enough to burn into carbon. At the end the carbon will collect at the centre of the star, shedding all outer layers to form a white dwarf. Nearly 99% of all stars in the galaxy end their life as a white dwarf.

A theory for the origin of life based on clay was forwarded by Dr. A. Graham caims-Sn\mith of the University of Glasgow in 1985 and adopted as a plausible illustration by just a handful of other scientists including Richard Dawkins. Clay theory postulates that complex organic molecules arose gradually on a pre-existing, non-organic replication platform made of silicate crystals in solution. Complexity in molecules developed as a function of selection pressures on types of clay crystals present. They then served as the replication of organic molecules independently of their silicate “launch stage”.

Ø After Urey Miller’s experiment, in 2006 another experiment showed that a thich organic haze might have blanketed Early Earth. An organic haze can form over a wide range of methane and carbon dioxide concentrations, believed to be present in the atmosphere of Early Earth. After forming, these organic molecules would have floated down all over the Earth allowing life to flourish globally.

Ø Another theory about the origin of life was given in 1980s by gunter wachtershauser in his theory. In contrast to the classical Miller experiments, which depend on external sources of energy (Such as simulated lightning or UV irradiation), “Wachtershauser systems” come with a built in source of energy, sulphides of iron and other minerals. They energy released from redox reactions of these metal sulphides is not only available for the synthesis of organic molecules, but also for the formation of oligomers and polymers. It is therefore hypothesized that such systems may be able to evolve into autocatalytic sets of self-replicating, metabolically active entities that would predate the life forms known today.

The biodiesel industry generates a tremendous amount of crude glycerol. The crude glycerol that is produced as a by-product in the transesterification reaction to make biodiesel typically contains high levels of salts. Most applications for glycerol require the elimination of these salts.
Conventional methods for glycerol purification are challenged with high operating costs.
By applying the latest advances in chromatography and polymeric separation technologies, Rohm and Haas and Novasep Process have developed an innovative, cost-effective solution for the purification of crude glycerol with high salt content. This AMBERSEP™ BD50 process ensures that the purification system is tuned to meet the quality specifications. The system maximizes the recycling of all process water and minimizes energy.

• Haplopappus gracilis a member of family composite, has only four chromosomes in somatic tissue.
• Ophioglossum regalis a member of pteridophytes has 1262 number of chromosomes in somatic cell.
• Longest metaphase chromosomes are found in Trillium
• Giant chromosome found in Dipteran are permanently at premetaphase stage and is about 300 mu long and 10 mu in diameter. Therefore it is easily visible in interphase.
