The ____ hypothesis, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. Topics of interest include how the biosphere and the evolution of life forms affect the stability of global temperature , ocean salinity, oxygen in the atmosphere and other environmental variables that affect the habitability of Earth.
Fill in the blank, which is also a figure from Greek mythology.

Show Answer
The Gaia Hypothesis, named after the Greek personification of Earth
The Gaia Hypothesis proposed by James Lovelock (1972) suggests that living organisms on the planet interact with their surrounding inorganic environment to form a synergetic and self-regulating system that created, and now maintains, the climate and biochemical conditions that make life on Earth possible.

X are a parody awards given to genuine scientists and researchers for their off beat inventions. The stated aim of the prizes are “first make people laugh, and then make them think”. Some of the recipients of the awards have been:
a bra that can be converted into a pair of gas masks
research on the “five-second rule”
converting old Russian ammunition into diamonds
discovery that chimpanzees can identify other chimpanzees individually from seeing photographs of their rear ends

X is a valley about 10 km east of Duesseldorf in Germany where a discovery was made in 1856. While it was not the first of its kind, it coincided with publishing of one of Darwin’s books.
This made the efforts to study the discovery serious, and the discovery itself ended up being named after the valley X.
What am I talking about?

Show Answer
Neanderthal, which comes from Neander 'name of the place' & thal 'German for valley'.
While there were earlier discovery of Neanderthal remains in Belgium & Gibraltar, they were misclassified as 'modern'. It was the release of Charles Darwin's On the Origin of Species in 1859 which spurred an interest in evolutionary studies.
Extremely detailed resource on the discovery of Neanderthal remains.
Watch how we know Modern Humans are related to Neanderthals.

In 1880s, Wilbur Atwater conducted experiments burning food items. A highly simplistic outcome of this experiments was the following equation:
X = 4*Carbohydrates + 9*Fat + 4*Protein
This output is followed the food industry till date.
What is this equation supposed to measure?

Show Answer
Calories in the food (including the number found on the label)
The experiment burned different food stuffs (while subtracting some fudge factors) to calculate the calories in our food. For every gram of Carbohydrates & Protein, 4kcal is released & for every gram of Fat, 9kcal is released. While not being super accurate, these results give a good indication of calories in food.

These type of drugs were originally created to fight Type 2 diabetes, however a happy side effect found was that they helped in reducing obesity. They work by introducing compounds like semaglutide, tirzepatide, etc. which reduce hunger & slow food movement hence making the person feel faster for longer.
Already a $10 billion market, these drugs are expected to become cash cows for their companies in the future.
Can you name the category of these drugs?

Show Answer
GLP 1 Drugs, named after the hormone Glucagon-like peptide-1
Currently sold by companies like Eli Lily, Novo Nordisk under brand names like Mounjaro & Wegovy.

This method has been successful due to the abundance of Carbon in organic matter and half life of its isotopes to be 5,730 years.
It has been used for scientific methods, like proving the validity of Dead Sea Scrolls, while also disproving the authenticity of artifacts like the Shroud of Turin.
Identify the method/science.

Show Answer
(Radio)Carbon Dating
It is based on the fact that radiocarbon (C14) is constantly being created in the Earth's atmosphere by the interaction of cosmic rays. The resulting C14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire C14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of C14 it contains begins to decrease as the C14 undergoes radioactive decay. Measuring the proportion of C14 in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calculate when the animal or plant died.

ENSO is a weather phenomenon which was originally named after Jesus Christ and is caused by the variation in winds blowing over the Pacific Ocean. It typically occurs every 2 to 7 years and is responsible for heavy rainfall on one of the Pacific, to droughts on the other.
Can you identify this weather phenomenon?

Show Answer
El Nino Southern Oscillation, or just El Nino in short. The weather pattern was discovered by sailors around Christmas time, related it to Christ himself. Its effects are not only restricted to the Pacific, but have the capability to affect global climate in general.

At the end of the World War I, the German navy sank their own naval fleet rather than handing it over the British Royal Navy, going against Treaty of Versailles. This was done at Scapa Flow, an archipelago north of UK.
The scrap from the sunken fleet became more valuable after World War II and is being currently used in a scientific tool.
Can you identify how these scraps are being used?

Show Answer
The steel from the scrap is used for Geiger counter, used to measure radioactivity. This is because the steel was formed in pre-atomic era and is not contaminated.
