...ine and soil. But even in that stable home, little variations occur. One plant in the A family might get a few more minutes of sunshine a day, another might get more water, but they pretty much grow up to be just like their parent.The identical offspring of Plant B grow up the same way, except more of the plant...deCODE discovers cause of major subtype of glaucoma
...n report the discovery of two common single letter variations (SNPs) in the sequence of the human genome that appear to account for virtually all cases of a major subtype of glaucoma. The SNPs are located in the LOXL1 gene on chromosome 15, and confer respectively 26-fold and 8-fold increases in risk of exfolia...OHSU turns mouse into factory for human liver cells

...ought. Where previously there were only 140,000 variations in DNA sequence described, it turns out there are 8.3 million. Moreover, the study found that the pedigrees of the 15 mouse strains studied are not what they were previously assumed to be. It appears they differ from each other to a far greater deg...After a decades-long search, scientists identify new genetic risk factors for multiple sclerosis
