The Cognitive Impact of Shift Work

Working in shifts can lead to cognitive decline due to the disturbance of the circadian rhythm and subsequent hormonal irregularities, as well as neurobehavioral issues. This decline can manifest in several ways, such as reduced processing speed, impaired working memory, psychomotor vigilance, decreased cognitive control, and impaired visual attention. Shift work disrupts the body’s natural sleep-wake cycle and can negatively impact overall health, including an increased risk for chronic diseases such as obesity, type 2 diabetes, and cardiovascular disease. Additionally, shift work has been linked to increased rates of depression, anxiety, and substance abuse. It is important for employers to consider the potential risks associated with shift work and implement measures to mitigate the negative effects on employees’ health and well-being.

The Imprisonment of Tick-Borne Encephalitis Virus Discoverers

In 1937, epidemiologist Tamara Safonova and virologist Alexandra Sheboldaeva made the groundbreaking discovery of Tick-Borne Encephalitis Virus. However, their achievements were overshadowed by accusations that they had intentionally spread the virus, leading to their sentencing to 18 years in Soviet labor camps.

This was a time of great political upheaval in the Soviet Union, as Stalin’s purges were in full swing. Many scientists, intellectuals, and other professionals were targeted as potential enemies of the state, and accusations of sabotage or espionage were common. Despite their significant contributions to public health, Safonova and Sheboldaeva fell victim to these suspicions.

Their imprisonment was not only a personal tragedy, but also a loss to the scientific community. The research of Safonova and Sheboldaeva would have undoubtedly continued to advance our understanding of tick-borne diseases, had they been allowed to continue their work.

Fortunately, in the decades since their imprisonment, their contributions have been recognized and celebrated. Today, Tick-Borne Encephalitis Virus is a well-known and studied disease, and Safonova and Sheboldaeva’s legacy lives on as pioneers in the field of virology.

In the early 20th century, a man named Charles Osborne…

In the early 20th century, a man named Charles Osborne had a medical condition called “harmonica tongue,” which caused him to hiccup continuously for 68 years. His hiccups began in 1922 and continued almost nonstop until his death in 1990, at the age of 97.

Osborne’s hiccups were so severe that he was unable to eat or drink normally and had to be fed through a tube. Despite numerous attempts by doctors to cure his condition, they were ultimately unsuccessful, and Osborne’s hiccups became a part of his daily life. Despite the challenges he faced, Osborne remained upbeat and even managed to find a measure of fame due to his unusual condition. He appeared on television and in newspapers and was interviewed by reporters from all over the world.

Scientist Claire Patterson spent…

Scientist Claire Patterson spent over 20 years trying to convince the public that lead was poison.

The inventor of leaded gasoline meanwhile once went to New Jersey to argue that leaded gasoline was perfectly safe, by pouring tetraethyllead onto his hands, and then putting a bottle of it under his nose and inhaling it for 60 seconds saying he could do it every day without any problems. He then had to leave work after being diagnosed with lead poisoning.
He also went on to invent Freon, a CFC that was later banned after being shown to be responsible for ozone depletion.

Then he got polio, so he invented another thing, a pulley system that let him pull himself out of bed. He would then die after becoming entangled in this and strangling himself.
