Receptor for Ebola Virus Identified

When an infection enters the body, the virus or bacteria heads staight for a receptor protein to mutiply and by doing that, the disease grows and grows until damaging or killing the host. Scientist have identified which the receptor protein that the Ebola and the Marburg viruses go to, and by doing so, they have been able to understand infections better. After arduous research, they have been able to develope an antibody that binds to receptor protein,and block the infection of both viruses. this is really good because the chance of surviving the Ebola virus ranges from 50 to 10 percent. Scientists are now looking for the receptor protein to other viruses to able to prevent those diseases also in time of outbreak.



Opinion


I don't know how much time it took for researchers to make this discovery, but the work is definitly worth. The Ebola and Marburg viruses have killed thousand of people around the world, especially in third world countries. Who ever takes this antibody will be less propence, or can be completly immune to these orrible diseases. I hope that in the near future, they will be able to prevent diseases such as HIV. This will open new door and it will bring hope to whole societiees that fear this disease.

Researchers Use Virus to Improve Solar-Cell Efficiency

Scientists have always tried to improve solar enery by continuasly searching for ways to make it easier and of couse, more economical. In this area, scientists have always came to the conclusion that carbon nanotubes can increase the ammount of electrons collected on a solar cell's surface. But, they've run into these two annoying little problems: That sometimes, when making nanotubes, they produce metals instead of semiconducters and they produce the oppisite effect of colleting electrons; hat's when the viruses come into play. Theuy found out that the virus can control the arrangment of the nanotubes on the surface, keeping the tubes separate so that they won't short ouot or clump together. By doing this, the ammount of solar energy collected improved by one-third. Scientists believe that this method can be improved by using different material.

Now that scientists have made solar power energy easier to do, it could be more economical in the near future. Hopefully, with more research, scientists will be able to discover more ways to increase energy gained with little cost and effort made. This discovery has opened new doors , now I guess, since more people are looking into solar energy, new, better discoveries will be made and it won't cost so much to depend on the Sun for energy. Solar energy is alot better for the environment than others ways that we have today like coal powered energy and petroleum, since we have an almost unlimited supply line. This will open new doors and we can all contribute to finding better ways to help the environment.
