On Wednesday, experts claimed to have unraveled prehistoric DNA mapping of 700,000-year-old horse. If true, this would be the oldest DNA mapping effort ever attempted. The second oldest horse mapping occurred in 2003 when horse bones were discovered in the oldest know permafrost in Canada’s Yukon. So what does this latest DNA mapping mean? Molecular biologists believe that species found in permafrost could be found and mapped to over a million years back. Being able to date back and find where certain species come from will only further development to where certain species are going.

Deidre’s explains that court ordered paternity tests are not easily obtained in the case where the woman puts another man’s name on the birth certificate. She recommends to move on and that regardless of the outcome, the relationship is over.
Researches have been able to identify, through a small amount of blood, a biomarker for colorectal cancer. Colorectal cancer, commonly known as colon or bowel cancer occurs from uncontrolled cellular growth within the colon or rectum. The study involves researches in Daejeon, South Korea and investigators from Yonsei University College of Medicine in Seoul, South Korea. Early detection is essential to the removal of colon cancer.
