Life in a puddle

This week's NSF Science 360 highlights include a discussion on the possible origins of life on Earth, suggesting it may have started in drying puddles through wet-dry cycles of amino and hydroxy acids. The impact of climate change on polar bears is also explored, noting their reduced hunting opportunities due to sea ice loss. The Engage experiment is introduced, which examines how real-time feedback on energy consumption can influence behavior, showing significant reductions in energy use when health messages are emphasized. The video concludes with science puns and a reminder to access more science content online.

What simple process is suggested to have potentially contributed to the origin of life on Earth?

• Exposing proteins to ultraviolet light

• Freezing amino acids in polar ice

• Combining DNA and RNA in volcanic ash

• Mixing amino acids with hydroxy acids in a drying puddle

What is the main reason polar bears are experiencing difficulties during their hunting season?

• Loss of sea ice affecting seal hunting opportunities

• Changes in prey migration patterns

• Warmer temperatures causing hibernation issues

• Increased competition from other predators

What is the primary focus of the Engage experiment?

• To study the effects of climate change on polar bears

• To understand how people respond to information about environmental impacts

• To analyze the economic benefits of renewable energy

• To develop new energy-saving technologies

How did families with children respond to the Engage experiment's messages?

• They increased their energy consumption by 19%

• They reduced their electricity consumption by 19%

• They showed no change in energy consumption

• They focused more on saving money than energy

What was the average reduction in energy consumption for those who received health-related messages in the Engage experiment?

• 5%

• 15%

• 8%

• 12%
