BEIJING/HANOI (Bloomberg): African swine fever is re-emerging in Asia, threatening to upend efforts to replenish national herds after the virus killed tens of millions of pigs in the region and created a huge shortage of meat protein.
Fresh outbreaks have been reported in China and Vietnam this year, and the disease has even landed on Malaysia s shores.
While new cases are scattered and isolated, they ve put governments on notice that the virus is alive and well and there could be dire consequences if it s not kept under control.
Rethinking “Why” Humans Began Cooking with Fire
Rob Dunn said the “key moment” when early humans first started cooking with fire “has at its core, just the tastiness of food and the pleasure it provides.” What this highlights is the importance of ancient noses, and the exceptionally close ties between flavor and human survival. The book explains that the ability to decipher flavor dimensions in food and drink, known as “retro-nasal olfaction,” in some early humans, made their chances of survival more likely. What this means is that ancient humans who had developed a stronger sense of smell, were able to sniff out the range of aromas generated by cooking meat.
Vaccines are an important tool in fighting porcine reproductive and respiratory syndrome, but the fast-mutating virus that causes the disease sometimes requires the production of autogenous vaccines tailored to particular variants.
The production of autogenous vaccines depends on the ability of scientists to isolate the virus, but sometimes thatâs a tricky process.
A new study from an Iowa State University researcher shows that a new cell line may offer a better alternative to the cell line most commonly used to isolate the PRRS virus. That could lead to more reliable processes for creating autogenous vaccines, but most autogenous vaccine producers would have to make dramatic changes to their processes in order to adopt the new cell line, said Jianqiang Zhang, associate professor of veterinary diagnostic and production animal medicine and lead author of the study.
