Using a smartphone to check cholesterol! NSF Science Now 19

The video covers four NSF-funded research topics: a smartphone accessory for cholesterol testing, the longevity of great white sharks, typists' implicit knowledge of keyboard layouts, and the impact of icebergs on Adelie penguins. Each section highlights innovative research and its implications, from health technology to marine biology and cognitive psychology.

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

• To measure blood pressure

• To track physical activity levels

• To analyze sleep patterns

• To monitor cholesterol levels using a smartphone

What did researchers discover about the growth and lifespan of great white sharks?

• Their growth rate and lifespan are unchanged

• They grow faster and live shorter lives than expected

• They grow at the same rate but live shorter lives

• They grow slower and live longer than previously thought

What surprising fact did researchers find about skilled typists?

• They memorize key positions when first learning to type

• They often cannot identify key positions on a blank keyboard

• They have explicit knowledge of key positions

• They can type without looking at the keyboard

How do Adélie penguins adapt to changes in their environment?

• By building nests in trees

• By adapting to seasonal changes in sea ice

• By changing their diet

• By migrating to warmer regions

What potential impact could increased frequency of extreme events have on Adélie penguins?

• They could become more aggressive

• Their population might increase

• They could temporarily disappear from their current habitat

• They might thrive in new habitats
