NSF Science Now: Episode 44

The video covers several scientific advancements funded by the National Science Foundation. It begins with Kenneth Catania's discovery of electric eels' ability to generate high voltage pulses, similar to a Taser, when threatened. Next, it discusses a new home blood clotting test developed by Dr. Andrew Stuckel, which aims to reduce healthcare costs and improve patient monitoring. The video then highlights Harvard's microbots, which use static electricity to perch and conserve energy. Finally, it introduces the IC Flood app, designed to report and manage flood conditions using crowdsourced data and innovative sensors.

What unique behavior do electric eels exhibit when they feel threatened?

• They hide underwater.

• They change color to camouflage.

• They leap out of the water and generate high voltage pulses.

• They swim away quickly.

What did Kenneth Catania use to demonstrate the effect of electric eels' voltage increase?

• A metal rod.

• A plastic crocodile head with a conductive metal strip and LED lights.

• A wooden stick.

• A real crocodile.

What is the primary purpose of the blood screening device developed by Dr. Andrew Stuckel?

• To detect heart rate.

• To check blood clotting levels for patients on blood thinners.

• To monitor blood sugar levels.

• To measure blood pressure.

How do Robo Bees conserve energy during flight?

• By reducing their weight.

• By flying at lower altitudes.

• By using solar panels.

• By perching on surfaces using static electricity.

What is the weight of the Robo Bee compared to?

• A real bee.

• A butterfly.

• A paperclip.

• A small bird.

What is the main function of the IC Flood app?

• To track hurricanes.

• To monitor air quality.

• To report flooding conditions in real-time.

• To predict earthquakes.

What additional feature do the IC Flood app's sensors provide?

• They predict snowfall.

• They improve monitoring and prediction of urban water systems.
