In a disappointing move, the Food and Drug Administration (FDA) did an about face in issuing a final regulation classifying dental amalgam without calling for stringent precautions for pregnant women and children. Last June, a court settlement filed by the Consumers for Dental Choice required the FDA to withdraw claims of mercury amalgam"s safety from its Web site and issue an advisory indicating: "Dental amalgams contain mercury, which may have neurotoxic effects
on the nervous systems of developing children and fetuses." "FDA broke its contract and broke its word that it would put warnings for children and unborn children for neurological damage," said Charles G. Brown, National Counsel for Consumers for Dental Choice, who brought the lawsuit compelling today"s action. 
The unique association between microorganisms and their hosts, whether insects, plants, or mammals, provides a fascinating view into how microbial symbionts adapt to changing biological environments. Insights into the diversity and complexity of symbiotic relationships are the focus of the current special issue of DNA and Cell Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The issue is available free online at http://www.liebertpub.com/dna "Symbiosis
is one of the most rapidly growing fields in biology. 
DLX5, a gene crucial for embryonic development, promotes cancer by activating the expression of the known oncogene, MYC, according to researchers from Fox Chase Cancer Center. Since the DLX5 gene is inactive in normal adults, it may be an ideal target for future anti-cancer drugs, they reason. Their findings are published in the July 31 edition of the Journal of Biological Chemistry, available online now. Previously the researchers found that a chromosomal inversion - a genetic
misalignment, where part of the chromosome containing the DLX5 gene gets flipped around during cell division - cooperates with another known oncogene, AKT2, to drive cancer in mice. In the current paper, the researchers discover that DLX5 binds to and actively promotes the activity of a gene known as MYC, which evidence has demonstrated is a potent factor in numerous cancers, including lymphoma, lung and pancreatic cancer. 
Nearly three decades after China implemented its one-child policy, the city of Shanghai is planning to encourage young couples to have a second child in an effort to address the country"s aging population and shrinking work force, the New York Times reports. The city"s plan is the most public effort made by the government to counteract a program that is "considered both a tremendous success and a terrible failure," the Times reports. The policy has managed
to keep population growth under control but also has led to forced abortions, according to the Times.The country is not abandoning the one-child policy, which applies mostly to residents in urban areas. Rather, the government is allowing more exceptions to the rule, with Shanghai -- where about 22% of its 20 million residents are older than age 60 -- leading the effort. China as a whole faces a similar problem seen in Shanghai, the Times reports. About 8% of the country"s population was older than age 65
in 2006.
