As you have probably heard, tests confirm that a wild animal market selling exotic meats in Wuhan China is at the epicenter of the current coronavirus outbreak. This leaves many people wondering just how viruses jump between species. Here is a timely video from YouTube answering that question:
I just read an interesting article from the Max Delbruck Center for Molecular Medicine in the Helmholtz Association that explained why human cells are typically quite resistant to bird flu. Bird flu (H5N1, H7N9, H5N6) does not readily spread between infected humans. In fact, most outbreaks involve only a handful to a few hundred individuals. But, on occasion, the infection can spread more easily leading to a pandemic. New research […]
Through the course of evolution vertebrates have apparently lost their gene-encoded viral defense mechanisms. These ancient defenses allow plants and insects to silence the expression of certain genes by using what is known as RNA interference. This natural defense system can be manipulated to create genetically modified crops that resist certain infections. However, a new study by researchers from the University of Leuven in Belgium examined over 40 organisms in […]
Check out this video from Reuters (via YouTube). It summarizes an exciting study from researchers at Imperial College London who were able to stop the progression of Alzheimer’s disease in mice by administering a modified virus to the animals. The virus worked by preventing the formation of the characteristic amyloid plaques that are responsible for causing damage to neurons in the brain. Importantly, the virus did not result in loss […]
