They cannot reproduce without being inside a living cell. Once inside a cell, viruses use the machinery of the cell to replicate themselves. MY LATEST VIDEOS Luckily for us the human body has lots of natural responses to protect us from viruses and other harmful pathogens. How does a virus...

Immunizations work by pre-infecting the body so it knows how to produce the right antibodies as soon as the virus starts reproducing. Also, because viruses reproduce so quickly and so often, they can often change slightly. Sometimes, mistakes creep into their genetic instructions. These changes ...

Remarkably, we do know for certain where the crossover happened because scientists can track it. Like all viruses, HIV mutates, and it does so at a constant rate. Scientists can use this rate of mutation to track the history and progress of the virus. Because of HIV's close resemblance ...
How often do mice reproduce? The house mouse breeds year-round inside structures such as homes. However, in its wild environment, the breeding period is generally from about April through September. Females generally have 5-10 litters per year and the litter size ranges from 3-12 pups, but ...
There are millions of viruses thought-out the world and many of them are deadly, take the Influenza virus for instance. The Influenza strain is a constantly changing virus; they change from year to year, and as the flu virus reproduces their genetic makeup may change. Due to the genetic ...

It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it ...
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
