Lab mice have been used for almost a century to test new drugs, study the impacts of specific environments on the body and improve the medical field. But, those mice don’t have the same immunities as humans and are raised in sterile environments. Scientists have recently started using wild mice to better recreate the immune systems of humans for more accurate results.

Mosquitoes are a real annoyance. They land on you, drink your blood, make you itchy and can carry deadly diseases. But you might have noticed that some people get bitten more than others. So, why does this happen? It turns out to be more complicated than you may think.

In the early days of microwave ovens, people worried that emitted radiation could be dangerous to their health. In what you might think is an odd twist, doctors now use microwave technology to treat cancer. It helps to alleviate pain and, in some cases, even cure some forms of cancer. You have to see it to believe it.
