   Dr. Mary Schweitzer, a North Carolina State University researcher, and colleagues at Harvard Medical School and Beth Israel Deaconess Medical Center have confirmed the existence of protein in soft tissue recovered from the bone of a 68 million-year-old T. rex. Their results may both change the way that people think about fossil preservation and present a new method for studying diseases such as cancer.

6. Ancient predator had strongest bite of any fish, rivaling bite of large alligators and T. rex
   11-28-2006 · EurekAlert!
   Dunkleosteus terrelli may have been the world's first apex predator. The force of its bite was remarkably powerful: 11,000 pounds. The bladed dentition of this 400-million-year-old extinct fish focused the bite force into a small area, the fang tip, at an incredible force of 80,000 pounds per square inch. This is the strongest bite force of any fish ever, and rivals the bite of large alligators and T. rex.

7. Paleontologists discover most primitive primate skeleton
   01-23-2007 · EurekAlert!
   The earliest branches of primate evolution are more ancient by 10 million years than previous studies estimated, according to an article featured in the Proceedings of the National Academy of Sciences. Researchers reconstructed the base of the primate family tree by comparing skeletal and fossil specimens representing more than 85 modern and extinct species. The team also discovered two 56-million-year-old fossils, including the most primitive primate skeleton ever described.

8. Most ancient case of tuberculosis found in 500,000-year-old human; points to modern health issues
   12-07-2007 · EurekAlert!
   Although most scientists believe tuberculosis emerged only several thousand years ago, new research from the University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.The discovery of the new specimen of the human species, Homo erectus, suggests support for the theory that dark-skinned people who migrate northward from low, tropical latitudes produce less vitamin D, which can adversely affect the immune system as well as the skeleton.

9. Detergents, eye rinses and other products with an on/off switch
   08-21-2007 · EurekAlert!
   Researchers at an American Chemical Society meeting will report the development of an unusual biological detergent, called a Pepfactant, a surfactant made from peptides, protein subunits. Its potential applications range from a laundry detergent that hardly needs a rinse cycle to a non-irritating eye rinse to increasing the amount of oil that companies can extract from a well. The development will be described in August at the society's national meeting in Boston.

10. Cow protein aids in treatment of gastrointestinal disorder
    05-16-2007 · EurekAlert!
    Recent evidence suggests that therapy currently used to treat Helicobacter pylori (H. pylori) infection, a major cause of upper gastrointestinal disorders, is unsuccessful in around 25 percent of cases. A new study, published in The American Journal of Gastroenterology, finds that adding a bovine protein called lactoferrin to the existing treatment may yield more effective results, with fewer of the side effects associated with common antibiotic treatment.
