The incredible bladderwort

This week's NSF Science 360 News highlights include the Ladderwort plant, which has a compact genome with more genes than a grape, suggesting rapid DNA changes. Scientists are also working on a lithium-air battery for electric cars, offering up to 10 times more energy density. At the University of Miami, a Net 0 Water Residence Hall treats and reuses water sustainably. These innovations could impact military bases and desert climates.

What unique evolutionary process is suggested to have occurred in the ladderwort plant?

• Cross-breeding with other species

• Natural selection through climate adaptation

• Rapid DNA duplication and deletion

• Gradual mutation over centuries

What is the primary chemical reaction involved in the lithium-air battery?

• Lithium and carbon dioxide

• Lithium and oxygen

• Lithium and nitrogen

• Lithium and hydrogen

How much more energy density could the improved lithium-air battery potentially provide compared to current batteries?

• Twenty times more

• Ten to fifteen times more

• Five to ten times more

• Two to three times more

What is the main feature of the Net 0 Water Residence Hall at the University of Miami?

• It uses solar power for water heating

• It relies on imported water for sustainability

• It treats and reuses water on-site

• It uses only rainwater for all needs

What potential future applications are mentioned for the Net 0 water system?

• Space exploration missions

• Agricultural irrigation systems

• Military bases and desert climates

• Urban residential areas
