Scientists worry about ecological balance
15 February 2022 / A recent study from Brazil shows that genetically engineered fluorescent ornamental fish (zebrafish, Dania rerio) have escaped from breeding facilities in large numbers and spread into regional river systems. The transgenic fish are sold in various countries as ornamental fish for aquariums under the trade name GloFish. The paper was published in the Studies on Neotropical Fauna and Environment journal, and was picked up in the current issue of Science, among others.
Findings relevant for planned marketing of GE laying hens
10 February 2022 / In experiments with zebrafish, researchers have shown that unintended effects of CRISPR/Cas applications are inherited in subsequent generations. They also found unusual patterns of inheritance. According to the scientists, the findings show that the effects of CRISPR/Cas applications on subsequent generations need to be examined in much greater detail.
Testbiotech is documenting the discussion
8 February 2022 / Testbiotech is providing an overview of the continuing discussion on the origin of SARS-CoV-2. The origin of the virus is still not known. Many experts suggest there was direct transmission from wildlife species to humans, but escape from a laboratory also remains a plausible scenario.
Regardless of which theory is correct, finding the origin of the virus is fundamentally important, as both safety in laboratories and the disruption of the wildlife ecosystems are principally human activities, which need to be much more carefully monitored resp. restricted.
Deficiencies in the risk assessment of Bt cowpea cultivated in Nigeria
1 February 2022 / A new scientific publication reports substantial deficiencies in the risk assessment of genetically engineered Bt cowpea approved for cultivation in Nigeria. The transgenic plants produce an insecticidal Bt toxin meant to protect the plants from the larvae of Maruca vitrata, which feed on the plants and are also known as pod borer. Testbiotech recommends discontinuing the marketing of the plants as well as additional in-depth investigations before planning any releases.
