NSF Science Now: Episode 41

The video discusses three NSF-funded research projects. The first project at Georgia Tech involves a wearable robotic limb that learns human movements and can assist in activities like music and surgery. The second project focuses on beluga whales in the Arctic, revealing their migration and feeding patterns through 15 years of data. The third project examines the impact of climate change on US forests, highlighting increased drought severity and the vulnerability of tree populations.

What is the primary function of the wearable robotic limb developed by Georgia Tech researchers?

• To assist in playing musical instruments

• To enhance human movement and activity

• To improve communication skills

• To perform complex mathematical calculations

What is the main food source for beluga whales as discovered by the research team?

• Plankton

• Krill

• Seals

• Arctic cod

How do researchers gather data about beluga whales' movements and diving patterns?

• Using satellite tags that activate when whales surface

• By observing them from boats

• By tracking their vocalizations

• Through underwater cameras

What has been the impact of climate change on US forests according to the NSF funded study?

• Increased biodiversity

• Decreased tree growth

• Increased severity of forest droughts

• Improved soil quality

Which region's forests are most affected by the changes in climate as per the study?

• Southern forests

• Eastern forests

• Western forests

• Northern forests
