NSF Science Now: Episode 19

The video discusses various NSF-funded research projects. It starts with a smartphone accessory developed by Cornell University engineers that can measure cholesterol levels using a camera. The next section covers a study on great white sharks, revealing they grow slower and live longer than previously thought. The third section explores typing skills, showing that skilled typists lack explicit knowledge of key positions. Finally, the video examines the impact of climate change on Adelie penguins, highlighting their adaptation challenges due to changing sea ice conditions.

What is the primary function of the Smart Card accessory developed by Cornell University engineers?

• To read cholesterol levels

• To monitor heart rate

• To track physical activity levels

• To measure blood pressure

What significant finding did the research team discover about great white sharks?

• They grow faster than previously thought

• They live significantly longer than previously thought

• They are more aggressive than other sharks

• They migrate more frequently than other marine animals

What method did researchers use to study the longevity of great white sharks?

• Tagging and recapture

• Radiocarbon dating

• Satellite tracking

• Genetic analysis

What surprising discovery was made about skilled typists?

• They can type faster than 100 words per minute

• They use a different typing technique than beginners

• They memorize the keyboard layout perfectly

• They cannot identify the positions of many keys

How do Adélie penguins adapt to changes in sea ice conditions?

• By changing their diet

• By migrating to warmer regions

• By huddling together for warmth

• By walking longer distances to reach food
