One breath could possibly save your life! NSF Science Now 27

The video discusses three NSF-funded projects. The first project involves smart headlights that reduce glare for night drivers by using a DLP projector to control light beams. The second project identifies sources of gas contamination in drinking water related to hydraulic fracturing, highlighting the need for improved well integrity. The third project introduces nanopillar labels that reveal hidden images when exposed to moisture, helping to combat counterfeit drugs.

What technology is used in the programmable headlight system to control the light beams?

• LED lights

• DLP projector

• Halogen bulbs

• Laser beams

What was identified as the primary cause of gas contamination in drinking water related to hydraulic fracturing?

• Faulty water pumps

• Natural gas leakage

• Poorly sealed boreholes

• Surface spills

What is the main purpose of the high-tech label developed by NSF and University of Michigan engineers?

• To improve shelf life

• To reduce production costs

• To prevent counterfeiting

• To enhance product aesthetics

How do the nano pillars in the high-tech label reveal hidden images?
