Incidents causing potential exposures to pathogens occur frequently in the high security laboratories. Lab incidents that lead to undetected or unreported laboratory-acquired infections can lead to the release of a disease into the community outside the lab.
The Canadian Border Services Agency (CBSA) intercepted Gang Li’s flight and found he was transporting seven undeclared test tubes of an unknown substance in his checked baggage. Laboratory testing confirmed the items included the following viruses: Peste des Petits Ruminants, Newcastle disease, Duck Adenovirus 1, and Parainfluenza Virus 5.
Researchers unveiled the latest feat in artificial DNA engineering: an eight-letter synthetic system called “hachimoji” DNA. The system is made up of four natural nucleotides and four synthetic ones that all fit seamlessly into DNA’s helical structure, maintaining its natural shape. These sequences spelled with these new letters pair predictably and can evolve just like natural DNA.
Scientists have launched a major new phase in the testing of a controversial genetically modified organism: a mosquito designed to quickly spread a genetic mutation lethal to its own species. Researchers have begun large-scale releases of the engineered insects, into a high-security laboratory in Terni, Italy.
The brains of two genetically edited girls born in China last year may have been changed in ways that enhance cognition and memory, scientists say.
Careful use of antibiotics, well-timed administration of vaccines and improved biosecurity can produce healthier calves.
Stephen Collett, University of Georgia veterinary medicine professor emeritus, details a hierarchy of three levels of biosecurity. All biosecurity concerns can be organized within these tiers, which make tackling a plan for biosecurity a more manageable and approachable task.
The World Health Organization (WHO) announced the formation of an international committee aimed at establishing uniform guidelines for editing human DNA in ways that can be passed down to future generations.
The plan seeks to prevent and control bird flu outbreaks and help form disease-free poultry farming zones and chains, thus minimizing the disease's impact on Vietnam's public health, food safety, and trading activities.
Scientists have developed a computer program, Environmental Monitoring With an Agent-Based Model of Listeria (EnABLe), that can simulate the most likely locations in processing facilities where foodborne pathogen Listeria monocytogenes might be found.
