Scientists have developed an improved technique to trace brain connections between neurons in zebrafish using vesicular stomatitis virus (VSV), enabling the visualization of connected neurons up to five days after infection. This breakthrough could provide insights into brain network connectivity repair after injury or disease.
Researchers have discovered a virus that can selectively infect and kill human melanoma cells, leaving normal cells unharmed. This breakthrough offers new hope for treating the deadliest form of skin cancer, which has seen a tripling of incidence over three decades.
A post-exposure vaccine has been shown to protect monkeys against the deadly Marburg virus. Researchers tested the vaccine in a study involving non-human primates and found it to be highly effective in preventing severe symptoms of the disease.
