4 Awesome Discoveries You Probably Didn’t Hear About This Week - Episode 29

The video explores four scientific advancements: robots mimicking hummingbirds for search and rescue, the evolution of the amylase gene in mammals, improvements in potassium oxygen battery technology, and the creation of a pan genome for tomatoes. These discoveries highlight the intersection of technology and biology, showcasing innovations in robotics, genetics, energy storage, and agriculture.

What is a key feature of the robots inspired by hummingbirds?

• They are powered by solar energy.

• They can fly faster than hummingbirds.

• They are heavier than hummingbirds.

• They can lift twice their weight.

What does the study on amylase gene evolution suggest about starch-eating mammals?

• They independently developed more amylase gene copies.

• They do not have the amylase gene.

• They have fewer copies of the amylase gene.

• They evolved from a common ancestor.

What problem does the new potassium-oxygen battery solve?

• It reduces the battery's weight.

• It increases the battery's charging speed.

• It prevents oxygen from degrading the anode.

• It makes the battery waterproof.

What is the significance of the tomato pan-genome?

• It helps in breeding pest-resistant tomatoes.

• It reduces the genetic diversity of tomatoes.

• It eliminates the need for pesticides.

• It focuses only on increasing tomato size.

How does the new battery design improve its longevity?

• By increasing the battery's size.

• By using a single porous layer.

• By allowing oxygen to reach the anode.

• By using three layers to control oxygen flow.
