Ironically, despite the horrors of war, armed conflict has a way of advancing medicine. Gruesome injuries sustained on the battlefield provide opportunities for surgeons to experiment and test new approaches for treatment. During World War II for example, blood poisoning, bronchitis, and other infectious diseases contracted by soldiers created a demand for broad spectrum antibiotics, which encouraged British scientists to find new ways to produce penicillin on a mass scale.
According to a common piece of folklore, you swallowed eight spiders in your sleep last year.

After all, insects and spiders are gross critters that belong outside in the dirt, not inside our home. And certainly, not inside our mouths while we sleep.
The human body is able to obtain information about our environment in unique ways. Our eyes convert photons of reflected light into electrical and chemical signals that our brain processes into images of the world around us. Our noses are full of specialized cells that detect millions (or even trillions!) of different scents floating around in our environment: aromatic flowers, the putrescent stench of skunk, and tart citrus fruits all activate neural signaling. Our ears are specialized for detecting the compression of molecules in the air, from the deep, low frequency rumbles of 20 Hz to the piercing screams of 20,000 Hz.
The human body is able to detect photons of light, airborne chemicals, and sound waves. But there is one ever-present force to which our bodies are seemingly agnostic: magnetism. Continue reading “BEEing like a Magnet”
