Effectiveness of a herpesvirus CMV-based vaccine against Ebola Posted: 15 Feb 2016 06:01 AM PST As the latest in a series of studies, researchers have shown the ability of a vaccine vector based on a common herpesvirus called cytomegalovirus (CMV) expressing Ebola virus glycoprotein (GP), to provide protection against Ebola virus in the experimental rhesus macaque, non-human primate (NHP) model. Demonstration of protection in the NHP model is regarded as a critical step before translation of Ebola virus vaccines into humans and other great apes.

Virtual reality therapy could help people with depression Posted: 15 Feb 2016 06:01 AM PST An immersive virtual reality therapy could help people with depression to be less critical and more compassionate towards themselves, reducing depressive symptoms, finds a new study. The therapy, previously tested by healthy volunteers, was used by 15 depression patients aged 23-61. Nine reported reduced depressive symptoms a month after the therapy, of whom four experienced a clinically significant drop in depression severity.
