Advances in treating infertility over the last three decades have also yielded a wealth of fascinating scientific information about the basics of human biology. Today, another mystery was explained by Oxford University scientists who showed just how a fertilized egg attaches to the womb and implants itself, thus beginning the pregnancy. When an embryo comes in contact with the lining of the womb, chemical signals are exchanged that allows the cells of the embryo to invade the womb and, eventually, connect with the mother's blood supply to form the placenta. In lab experiments, the Oxford scientists discovered that two specific proteins are involved in this process."We have shown that two proteins, called Rac1 and RhoA, control the invasion," said Helen J. Mardon of Oxford University. "The first stimulates cells in the womb lining to move and allow the embryo to invade and implant properly while the second inhibits this. We believe this controlled balance of the two proteins is critical for successful implantation of the embryo."If the balance between these two proteins is altered, the cells of the womb lining won't move aside to allow for implantation, the researchers said. The failure of implantation is a major cause of infertility. Understanding the process could lead to the development of medications that help embryos implant properly. The study is published today in Proceedings of the National Academy of Sciences. -- Shari Ro ...

A recent federal decision refusing to protect wolverines in the western United States is a case of political considerations winning out over scientific findings by U.S. Fish and Wildlife Service experts, according to a coalition of 10 conservation groups that filed suit today in U.S. district court. The groups are challenging the agency's decision to deny wolverines protection under the Endangered Species Act. read more ...

A couple of Baylor professors, Paul Glanzer and Wesley Null, have written a profoundly silly op-ed in a Texas newspaper taking the bizarre position that the State Board of Education shouldn't listen to Biologists when developing the biology curriculum. Some state Biologists claim they know the most about this interdisciplinary relationship, but they are wrong. Why should we trust Biologists over religion professors, curriculum professors and others who spend their lives studying and teaching these subjects? We can think of many good reasons not to trust Biologists on matters of religion and curriculum. A recent statement by a biologist affiliated with the 21st Century Science Coalition highlights a problem with listening to "experts" who are out of their specialized field. Speaking of the relationship between religion and curriculum, that biologist said, "It's time to keep religion and faith in the Sunday schools and not in the public schools." That position is a view that many legal, religious and educational experts outright reject. Read the rest of this post... | Read the comments on this post... ...
