Can Roller Coasters Help You Pass Kidney Stones?

The video discusses a study suggesting that riding a moderately intense roller coaster, like Big Thunder Mountain Railroad at Walt Disney World, may help pass small kidney stones. Researchers created a model kidney to test this theory, finding that stones passed more frequently when sitting at the back of the ride. The video also covers a study on Earth's temperature changes over the past two million years, indicating a warming trend linked to CO2 levels.

What was the main finding of the study involving the Big Thunder Mountain Railroad roller coaster?

• Riding the roller coaster can help pass small kidney stones.

• The roller coaster is too dangerous for people with kidney stones.

• The roller coaster can cure all types of kidney stones.

• Riding the roller coaster has no effect on kidney stones.

What was a significant limitation of the roller coaster study?

• It was conducted on multiple roller coasters.

• It used real patients instead of a model kidney.

• It only tested one roller coaster ride.

• It proved that all roller coasters are effective.

What does the study published in the journal Nature estimate?

• The average rainfall patterns over the last century.

• The future population growth of Earth.

• The best amusement parks for scientific research.

• The average surface temperatures of Earth over the last two million years.

What challenge is mentioned in understanding Earth's temperature changes over time?

• Overabundance of global temperature records.

• Too many consistent data sources.

• Difficulty in stitching together different temperature estimation methods.

• Lack of interest in climate studies.

What is the predicted impact of current CO2 levels on future global temperatures?

• A stabilization of global temperatures.

• A decrease in global temperatures.

• No change in global temperatures.

• An increase in global temperatures by three to seven degrees Celsius.
