The document discusses research into two viruses - Ebola virus and a protein called NPC1 that may be involved in the virus's ability to infect cells. It also discusses research into a gene called FGF20 that is required for proper inner ear development in mice and mutations in this gene may cause deafness in humans. The research highlights the importance of investigating genetic factors involved in diseases at a molecular level in order to work towards cures and treatments.

9. OBSERVATION Taken from: ttp://lanieve2.blogspot.com/2011/05/arreglar-el-mundo.html I think we must investigate more about this kind of diseases in a molecular level, because they have a high mortality and may occasions epidemics. If we get a cure is possible to prevent many deaths.

14. OBSERVATION Taken from: http://www.ciber-arte.com/arte/index.htm Investigate about genetic mutations that cause disease is very important for the biology, so I think that every day is necessary depth on these topics with to find a proper and ethical way to solve these problems.

15. MEDICAL UTILITY

16. MEDICAL UTILITY Taken from: http://portal.uniquindio.edu.co/noticias/?m=201007&paged=3 The investigations in experimental models are important because it allows medical advances and new discoveries in favor of human health.

17. MEDICAL UTILITY Taken from: http://www.conciencianews.com/index.cfm?p=articulos&id=45 Is important to use all our resources, such as experimental models in order to find the cure for all diseases, bearing in mind human life and proper management to organisms used for investigation.

18. MEDICAL UTILITY Taken from: http://www.elconfidencial.com/salud/2011/enfermedades-raras-geneticas-abogan-seleccion-genetica-20110301.html These investigations are essential to obtain further solutions in the field of human health, in this case the most age-related and noise-induced hearing loss is due to the miss of outer hair cells. If we can find ways to regenerate these cells could solve one of the problems that affect our sense of hearing.
