Summary:   "Others argue that cloning is unnatural. But nature wants us to pass on our genes; if cloning assists in that effort, nature would not be offended. Moreover, cloning itself isn't new; there have been many species that reproduced clonally and a few that still do." (Wired) This point-of-view article discusses why we should embrace cloning, and correlates it to an act of natural reproduction.

The researchers produced the cells by using strands of genetic material, instead of potentially dangerous genetically engineered viruses, to coax skin cells into a state that appears biologically identical to embryonic stem cells....The alternative cells, known as induced pluripotent stem cells, or iPS cells, appear to have many of the same characteristics as embryonic stem cells but are produced by activating genes in adult cells to 'reprogram' them into a more primitive state, bypassing the moral, political and ethical issues surrounding embryonic cells. Until now, however, their use has been limited because the genetic manipulation required the use of viruses, raising concerns the cells could cause cancer if placed in a patient. That has triggered a race to develop alternative approaches." (Washington Post) The discovery of a new method for reprogramming adult stells to become stem cells is reported.

Congress should also eliminate the current confidentiality requirements so that safety data submitted to FDA and the agency's analysis of that data can be reviewed by outside experts before GE [genetically engineered] animals are approved.

Summary:   "University of California-Davis professor James Murray knows his experiments with human genes and goats give some people the creeps. Crossing anything human with four-legged hoofers evokes images of mythical half-man, half-animal centaurs from ancient Greece. In reality, genetically altered goats look and behave no differently than regular ones....Murray and fellow animal scientist Elizabeth Maga engineered a small herd of Alpine and Toggenburg dairy goats to produce high levels of a human antibiotic-like protein in their milk. Just as mother's milk helps protect infants from germs, the researchers figured, humanized goat's or cow's milk would better defend dairy animals and their offspring from illness. Germ-fighting milk might also slow spoilage, prolonging the shelf life of dairy products. The scientists' ultimate question, though, is a humanitarian one: Could the same procedure produce fortified powdered milk and, eventually, genetically modified goat herds for poor regions of the world?" (Sacramento Bee) The potential development of a genetically-modified version of goats milk containing high concentrations of the beneficial protein lysozyme is discussed.

Summary:  In this article about genetically modified animals, the author raises questions about whether government regulation adequately ensures the safety of consumers, animals and the environment. "The subtext of any discussion about the science of GE [genetically engineered] animals is whether this is something the public wants or is ready for. Regulation, if done well, would increase consumer confidence in the efficacy and safety of the animals. But the different ways government has proposed regulating such new 'products' raises concerns from consumer and environmental groups, and a 2002 National Academy of Sciences Commission."

Summary:  This profile of biologist J. Craig Venter highlights his creation of the first human-crafted genome. "He was the leader of one of two teams that in 2000 sequenced the human genome--the entire 25,000-gene cookbook that makes us people in the first place and not chimps or birds or banana trees--and he has conducted the same work with many other organisms. But Venter, 61, may have just done something that is at once more thrilling and promising and unsettling than all that. According to a just-released [Jan. 24, 2008] paper in the journal Science , he has gone beyond merely sequencing a genome and has designed and built one. In other words, he may have created life."

Summary:  "A growing chorus of medical researchers say our bacteria-killing zealotry is misguided. Instead of fighting bugs, they argue, we should train them to do our bidding and then set them loose in our bodies. The trouble is keeping them there....But the few microbes that have made it into limited human trials--a cavity stopper, a tumor destroyer, a bowel soother--have been enticingly successful. And so the first standoff over body-ready bugs is taking place before the review boards of medical centers and government regulatory agencies, the people who will decide if the world is ready for engineered superbugs." (Popular Science) This article reviews the therapeutic potential of genetically modified organisms (GMOs) to prevent dental cavities, fight Crohn's disease and cancer, and prevent tuberculosis and other infections.
