Repairing corneas
A new biologically artificial cornea, made of collagen will soon induce healing by using the natural substances in a real cornea. Vision depends on a healthy cornea, which is the film covering the ice surface and helps you focus. Over 40,000 people last year had transplanted cornea is. 10 million people go blind because of this problem.
Human collagen is grown in yeast and mold it into a contact lens the shape of the cornea. Then a silver collagen is placed in the eye to coax the natural corneal cells to regrow and restore vision with an artificial cornea. It repairs the cornea from within. Linkoping Univ, Sweden 8.26.10
stem cell expansion
A product of purine, StemRegenin1 (SR!) helps the expansion of human hematopoetic stem cells (HSC). the SR one blocks the activity ofaryl hydrocarbon receptors, expands Cd 34 cells, and increases the number of HSC 17 times. Source: science,September 10.2010
SOURCE OF GLOBAL WARMING
Atmospheric methane is the leading cause of green house gases that are pushing global warming. It is a byproduct of many farming activities, including wetland rice cultivation, and cattle herding. Source: Science 7.11.08
Ty Rex
Tyrannosaurus, have become valuable research subjects since the abundance of archaeological finds. Over the last 10 years, 15 new species were found and over the last year another six were discovered and described. Some of the bones are over 100 million years old. Scientists are studying the dinosaur growth dynamics , population structure, feeding, locomotion, biography, and soft tissue morphology.
They are closely related to birds, more than to large theropods. The large Tyrannosaurs matured around 20 years of age and rarely lived more than 25 years. They could not run as fast as even our racing horses today. They had birdlike postures, long legs, and large pelvic limb muscles. Their jaws structures show they dipped deeply into carcasses often through bones, pulled back, creating long cuts in the bones, and ingesting the bones for food. The bite force was enormous, and exerted tremendous stress on the skull. Their necks were very important in generating pulling forces on food items. From the rigors of reproduction, they often died at midlife and had a very short reproductive lifespan. During encounters, they bit each other in the face. They preferred wet areas and dominated western North America. Science September 17.2010
