2013-07-11 15:24:22

Penn State The Y chromosomes of cattle have more genes and are more active than the Y chromosomes of other primates, according to researchers. This discovery may help biologists better understand how cattle and other mammals evolved, as well as help animal breeders and farmers better maintain and enhance fertility in the cattle industry, said Wansheng Liu, associate professor of animal genomics, Penn State. "Low fertility is a big problem for the dairy and beef industry," Liu said....

Findings of disrupted micronuclei may prove to be a valuable tool for detecting cancer Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, published on July 3 in Cell, a team of scientists at the Salk Institute...

New research has found that routine screening using a non-invasive test that analyzes fetal DNA in a pregnant woman's blood can accurately detect Down's syndrome and other genetic fetal abnormalities in the first trimester. Published early online in Ultrasound in Obstetrics & Gynecology, the results suggest that the test is superior to currently available screening strategies and could reshape standards in prenatal testing. Current screening for Down's syndrome, or trisomy 21, and...
