To the Editor: Recently, the directors of Biosafety Level 4 (BSL-4) laboratories in the United States published their views of the requirement of having ≥2 persons present at all times while biological work is undertaken in a BSL-4 laboratory (1). They concluded that safety and security would be better assured in some situations by video monitoring systems rather than by the presence of a fello...

Most governments have developed, or are developing, national biosafety frameworks to enable them to address known and potential risks associated with the introduction of GMOs into their territories, and these regulatory systems may have a great impact on biotechnology research – not only at the stage of environmental testing, but also during laboratory studies. These national systems are in tur...

Over the years, genetically modified organism (GMO) development and regulation in China have regularly attracted international attention. In the early 1990s, China became the first country to commercialize a genetically modified (GM) crop with planting of a virus-resistant transgenic tobacco variety on a relatively large scale, while other parts of the world were debating about the risks of GMO...

One usually thinks of plant biology as a non-controversial topic, but the concerns raised over the biosafety of genetically modified (GM) plants have reached disproportionate levels relative to the actual risks. While the technology of changing the genome of plants has been gradually refined and increasingly implemented, the commercialization of GM crops has exploded. Today's commercialized tra...
