Re: Any ideas for vaccine development or anti-viral drugs???

... PMOs targeting sequences of viral mRNAs for the viral proteins (VPs) VP24, VP35, and RNA polymerase L protected rodents in both pre- and post-exposure therapeutic regimens. In a prophylactic proof-of-principal trial, the PMOs also protected 75% of rhesus macaques from lethal EBOV infection. ...

Re: Vitamin D absorption for different skin types

This seems to be an area that is just beginning to draw research interest. Darker skin evolved in high light-exposure populations to protect deeper skin layers from UV damage, but tones lightened in pops with lower exposure, to allow enough UV to reach the D-generating skin tissues. ...
