NSF SCIENCE NOW: EPISODE 52

The video discusses the impact of road salt on freshwater lakes, highlighting a study that found increased salinity in lakes near roads. It also covers how temperature affects mosquito-borne diseases, with optimal transmission at 84°F. Research on Parkinson's disease reveals neuron manipulation can alleviate symptoms. Lastly, a study shows that engaging young girls in STEM activities can reduce the technology interest gap between genders.

What is the primary cause of rising salinity in North American freshwater lakes?

• Agricultural runoff

• Industrial waste

• Road salt runoff

• Natural mineral deposits

Why are lakes more vulnerable to pollution compared to rivers?

• Rivers have more vegetation

• Lakes are larger in size

• Water remains in lakes for longer periods

• Lakes have more wildlife

At what temperature do mosquito-borne diseases like Zika and dengue peak in transmission?

• 72 degrees Fahrenheit

• 84 degrees Fahrenheit

• 90 degrees Fahrenheit

• 78 degrees Fahrenheit

Which regions are likely to see increased transmission of mosquito-borne diseases due to rising temperatures?

• Northern Europe

• Southern United States and northern Mexico

• Central Africa

• Eastern Asia

What is the main clinical target for treating Parkinson's disease?

• Thalamus

• Basal ganglia

• Cerebellum

• Hippocampus

What was the surprising result of the study involving young girls and technology activities?

• Girls showed no interest in technology

• Girls preferred storytelling activities over programming

• A 42% reduction in the technology interest gap between girls and boys

• Boys outperformed girls in programming tasks

What percentage of high school girls currently select computer science as a college major?

• 3.5%

• 2.0%

• 0.4%
