It is only when one toils and sweats it out that success is nourished and sustained.

This is really cool, novel stuff," Jan Amend, a researcher at the University of Southern California, who was not involved in the study, wrote in an email to Live Science.

The study reflects the increasingly popular idea that a simple, everyday source of power, not a rare occurrence like a lightning strike, could have provided the power to initially create life, he said.

The team proposed that a precursor to that cellular pump evolved in the membranes of the proto-cells.

The membrane started out very leaky, but over time, the membranes would have slowly closed, preventing much larger sodium particles from leaving the cell while smaller protons could still slip through.

The thorns remind one of how success and happiness can be evasive and thus not to feel disappointed and disheartened rather remember that the pain of thorns is short-lived, and the beauty of life would soon overcome the prick of thorns.

Those, who are under the impression that life is a bed of roses are disillusioned soon and become victims of depression and frustration.Authors of the new theory argue the environmental conditions in porous hydrothermal vents — where heated, mineral-laden seawater spews from cracks in the ocean crust — created a gradient in positively charged protons that served as a "battery" to fuel the creation of organic molecules and proto-cells.Later, primitive cellular pumps gradually evolved the ability to use a different type of gradient — the difference in sodium particles inside and outside the cell — as a battery to power the construction of complex molecules like proteins.A new theory proposes the primordial life-forms that gave rise to all life on Earth left deep-sea vents because of their "invention" of a tiny pump.These primitive cellular pumps would have powered life-giving chemical reactions. 20 in the journal Cell, could help explain two mysteries of life's early origin: How did the earliest proto-cells power chemical reactions to make the organic building blocks of life; and how did they leave hydrothermal vents to colonize early Earth's oceans?Leaving the vents At that point, primitive cells used the thin, serpentine walls of the vent to corral the new carbon-based molecules together into precursors of cells and used the charge gradient in the environment to power the building of more complex organic chemicals.But in order to leave the vent, primitive cells would have needed some way to carry a power-producing gradient with them — think battery pack.There is no human being on Earth, strong, powerful, wise or rich, who has not experienced, struggle, suffering or failure.No doubt, life is beautiful and every moment – a celebration of being alive, but one should be always ready to face adversity and challenges.Now, Lane and William Martin, of the Institute of Molecular Evolution at the Heinrich Heine University in Germany, propose that the rocky mineral walls in ocean-floor vents could have provided the means.The theory goes: At the time of life's origin, the early ocean was acidic and filled with positively charged protons, while the deep-sea vents spewed out bitter alkaline fluid, which is rich in negatively charged hydroxide ions, Lane told Live Science.
