NSF Science Now: Episode 34

The video covers four innovative studies: a University of Illinois study on teen driving behavior influenced by parental presence, a robotic exoskeleton named Harmony developed by UT Austin for rehabilitation, a new Wi-Fi technology called WIFO by Oregon State University that uses LED lights to enhance bandwidth, and a smartphone app for detecting sleep apnea developed by the University of Washington. Each study highlights advancements in technology and behavioral science aimed at improving safety, health, and connectivity.

What effect does a mother's presence have on a teen's driving behavior according to the study?

• Increases risky driving

• Increases speed

• Decreases risky driving

• No effect on driving behavior

What is the primary purpose of the Harmony exoskeleton?

• To improve posture

• To assist in walking

• To provide physical therapy

• To enhance athletic performance

How does WIFO improve Wi-Fi bandwidth?

• By reducing device connections

• By increasing signal strength

• By utilizing LED lights

• By using multiple antennas

What is a key feature of the WIFO system?

• It requires no additional hardware

• It can send data up to 100 megabytes per second

• It only works in open spaces

• It is incompatible with current Wi-Fi systems

What does the Apnea app use to detect breathing changes?

• Temperature sensors

• Audible sound waves

• Infrared sensors

• Heart rate monitors

What is the accuracy range of the Apnea app in detecting respiratory events?

• 80-85%

• 100%

• 90-94%

• 95-99%

What potential benefit does the Apnea app offer to users?

• A cure for sleep apnea

• A noninvasive way to test for sleep apnea at home

• Immediate treatment for sleep apnea

• A way to improve sleep quality instantly
