Could Humans live Forever?

The turritopsis nutricula species of jellyfish may be the only animal in the world to have truly discovered the fountain of youth.
Since it is capable of cycling from a mature adult stage to an immature polyp stage and back again, there may be no natural limit to its life span. Scientists say the hydrozoan jellyfish is the only known animal that can repeatedly turn back the hands of time and revert to its polyp state (its first stage of life).
The key lies in a process called transdifferentiation, where one type of cell is transformed into another type of cell. Some animals can undergo limited transdifferentiation and regenerate organs, such as salamanders, which can regrow limbs. Turritopsi nutricula, on the other hand, can regenerate its entire body over and over again. Researchers are studying the jellyfish to discover how it is able to reverse its aging process.

Because they are able to bypass death, the number of individuals is spiking. They're now found in oceans around the globe rather than just in their native Caribbean waters. "We are looking at a worldwide silent invasion," says Dr. Maria Miglietta of the Smithsonian Tropical Marine Institute.

Beef ate chicken Feces

>> Thursday, April 29, 2010


A recent investigation into industrialized agriculture feeding practices has revealed some disturbing information of which many may not be aware. Commercial animal husbandry practices often involve feeding livestock mass amounts of animal waste, including chicken litter, which contains chicken feces, bedding, feathers, and other unknown residue.

Long before the days of industrialized agriculture, leftover table scraps and produce unfit to be sold were the type of waste products farmers fed to cows and other livestock, in addition to the grasses and other natural food they already ate. The waste of old was edible, nutritious and suitable for animals.

Chicken litter works great as a soil fertilizer because it adds nitrogen, nutrients and other organic matter to soil. It has long been common practice to recycle it on nearby land.

However, today's massive chicken factories produce a glut of litter that these factory farms do not know what to do with. Their solution has been to sell it to cattle feedlots, where cows consume up to two million tons of it every year.

Chicken litter is not the only disgusting waste product being fed to cows that millions of Americans end up eating as beef. Feedlot operators are also feeding leftover waste products from corn-ethanol production. Such byproducts contain antibiotic residues and are implicated in prompting the proliferation of the E. coli virus.
