The Amazing Story of How Malaria Gave Birth to Mauve

May 15, 2024 by Lochlan DuVal

The race for a cure to malaria, led to the invention of the mauve dye.

It would be fairly safe to assume that if given a mauve bridesmaid’s dress or mauve curtains, most modern women would be less than enthusiastic. For years, the color mauve’s reputation has been far from fashion-forward, maybe even backward? But this wasn’t always the case.

Mauve enjoyed time in the limelight during the 19th century when the first synthetic dye mauveine, later nicknamed “mauve,” was accidentally and serendipitously discovered during the search for a malaria cure.

How Old is Smallpox?

May 13, 2024 by Lochlan DuVal

Particles of chickenpox has been found in mummies.

Smallpox, is a contagious illness that has a mysterious origin, as well as a long history.

Recently, tiny particles of the disease were discovered on an Egyptian mummy, identified as Pharaoh Ramses the V. The pharaoh reigned from 1150 – 1145 B.C., leaving the mummy 3,000 years old. In recent years, traces of smallpox were also found on two other Egyptian mummies, reigning during the Egyptian Dynasty from 1570 – 1085 B.C.

If smallpox can be found in ancient pharaohs, then how old can it be? Millennia later, there’s still much debate over this issue.

Why Hasn’t Polio Been Eradicated?

April 29, 2024 by Lochlan DuVal

Although the cases are rare, polio is still present in today's society.

During the 1940s and 1950s, Americans were hit with a plague. The disease spread fear as quickly as it filled hospital beds. The plague was Polio, and no one was exempt.

Even a President of the United States, Franklin Delano Roosevelt, spent his time in office in a wheelchair due to paralysis caused by polio.

For Americans, the widespread epidemic has passed. According to the Mayo Clinic, the last naturally-occurring case of polio in the U.S. happened in 1979. Despite that knowledge and the discovery of an effective vaccine back in 1953, we still need to be wary of the disease. Unlike the iron lung that was used in treatment, polio isn’t a thing of the past.

In honor of National Immunization Awareness month, read on for a brief history of the disease and how vaccine development has helped eradicate yellow fever in many nations.

April 15, 2024 by Lochlan DuVal

Bacteria in Petri Dish

Many have never heard of Legionnaires’ disease, but this bacteria-caused illness is making headlines after reported outbreaks in New York City this summer. The disease was blamed for 12 deaths over 119 reported cases until the outbreak was declared over by early August of 2015. However, in October of this year, three Chicago schools shut down due to reports of possibly high risk of contracting the disease. In both cases, the bacteria were traced to cooling towers in the city. In reality, Legionnaires’ disease affects thousands of people annually in the United States.
