||December 2014 Edition: Germs
|It’s that dreaded flu season again! Most of us unfortunately know what the flu feels like, but have you ever wondered what it looks like? When we picture the Flu virus or any germ for that matter, we imagine one of those creatures from the Mucinex commercial on television. Green, slimy and gross! Or maybe you picture some kind of cuddly creature with googly-eyes? No matter what it is you think germs look like, they all look and act completely different!
Germs are tiny organisms, or living things, that can cause disease. Germs are so small and sneaky that they creep into our bodies without being noticed. In fact, germs are so tiny that you need to use a microscope to see them. When they get in our bodies, we don't know what hit us until we have symptoms that say we've been attacked!
There are four types of germs that can be spread. These include bacteria, viruses, fungi, and protozoa. Let’s look at what the four different types of germs are and what they actually look like after being magnified under an electron microscope!
Bacteria [BACK-teer-ee-uh] are single celled organisms that can live inside or outside of the body that cause infections like sore throats, ear infections, or pneumonia. Usually most bacterial infections can be treated with an antibiotic medication prescribed by your doctor.
What we think bacteria looks like What E. coli bacteria actually looks like
Viruses [VY-rus-iz] rely upon animals, humans or its host in order to grow and reproduce. When viruses get inside peoples’ bodies they can spread quickly and can make them sick. Viruses cause diseases like chicken pox, measles, and the flu. They are not treatable by antibiotics, however, there are antivirals that are effective against a few viruses like influenza or “the flu”.

September 2014: All American Breakfast Month
“Cereal commercials, nutritionists and your mother all agree—breakfast is the most important meal of the day. That’s why Congress has declared September to be “All American Breakfast Month!”
Breakfast over the past few hundred years has changed drastically. The pilgrims used to break the fasting from dinner and sleeping all night by eating cornmeal mush and apple cider in the mornings. It wasn’t until 1906 when the concept of breakfast changed forever. That year was the defining moment for John Harvey and Will Keith Kellogg with their discovery of how to make the first Toasted Corn Flake cereal. With the invention of cereal, breakfast time turned into a matter of convenience. It was all about how to eat breakfast quicker. The first packaged hot cereal debuted in 1919 followed by packaged biscuit mixes by the 1930’s. It wasn’t until 1964 however, until the ultimate convenient breakfast food made its first introduction, the Pop-Tart.
Decemeber 2013: The Curious Evolution of Holiday Lights!
During the Holidays, we see all types of colorful lights! People decorate the outside and inside of their homes with lights that are switched on ceremoniously in neighborhoods across the globe. This tradition dates back to the 17thcentury when people first began putting lights on their Christmas trees by attaching small candles to the branches using wax or pins, according to the Great Idea Finder. But, it wasn’t until the late 19thcentury, that decorating with small glass lanterns with lit candles really took off. As a result of using candles, most people didn’t put up their lights until Christmas Eve due to the risk of fire.

No matter the age, the gift of science can fuel curiosity, ignite inspiration, and motivate our lives in so many different ways!
As we enter into this holiday season, we'd like to say thank you to our loyal HTHT customers for allowing us to be a part of their scientific discovery throughout this past year. This December, we challenge you to step into the shoes of a curious chemist, an eager environmentalist, peppy paleontologist or maybe even a mighty meteorologist and begin to discover how the world around us works, one test tube at a time!
