Hank Green discusses recent scientific news, including Mars Rover findings, Mercury's organics and ice, climate change impacts on ocean acidity, and innovations in mRNA vaccines. The video highlights the excitement and challenges in space exploration, environmental issues, and medical advancements.

What was the initial reaction to the Mars Curiosity Rover's findings?

• Disappointment due to lack of data

• Indifference from the scientific community

• Confusion about the rover's mission

• Excitement over potential groundbreaking discoveries

What did NASA discover on Mercury?

• New moons

• Volcanic activity

• Water ice and organic compounds

• Signs of life

How many months of above-average global temperatures have been recorded consecutively?

• 500 months

• 332 months

• 100 months

• 200 months

What is a consequence of increased CO2 in the oceans?

• More marine life

• Decreased salinity

• Increased ocean acidity

• Higher water temperatures

What is the main concern with ocean acidity?

• It increases ocean salinity

• It depletes calcium carbonate, affecting marine life

• It affects the color of the ocean

• It makes the ocean warmer

What is the potential benefit of mRNA technology in flu vaccines?

• It is more expensive to produce

• It provides immunity for a single season

• It requires multiple doses

• It offers long-lasting immunity

Why is mRNA considered more advantageous than traditional vaccines?

• It requires refrigeration

• It is cheaper and faster to produce

• It can be incorporated into the genome

• It is more stable than DNA

What unique feature do ferrets have that makes them useful in vaccine testing?

• They are resistant to all viruses

• They have immune systems similar to humans

• They can survive in extreme temperatures

• They have a similar digestive system to humans

What additional type of immunity do mRNA vaccines activate?

• No additional immunity

• Active attack immune cells

• Antibody immunity only

• Passive immunity

What does Hank Green encourage viewers to do at the end of the video?

• Disregard climate change

• Avoid flu vaccines

• Ignore scientific developments

• Stay informed about scientific news
