Neuroscience

Diagram showing how visual input from an apple is processed by the eye and brain, highlighting visual input, predictive signal, and brain's anticipation of what the eyes see.

Your brain predicts what you’re about to see before the visual information fully arrives!

Animals

Diagram of a monarch butterfly on a leaf, illustrating chemical structure, chemoreceptors, and insect behavior.

Butterflies can taste with their feet using a special chemical sensors called chemoreceptors!

This makes it more efficient in searching for a host plant for their eggs.

Plants

Animated illustration comparing natural banana containing approximately 400 mg of potassium to uranium-238, a radioactive material with about 4,000,000 mg of potassium.

Bananas are naturally radioactive!

It’s because they contain potassium (but only a small amount so don’t let that stop you from eating one!)

Physics

A diagram demonstrating how time moves faster at the top of a mountain than it does at sea level.

Time moves slightly faster at the top of a mountain than at sea level!

This is due to gravitational time dilation.

Sharks existed around 60 million years before trees on Earth!

Evolutionary timeline showing sharks 450 million years ago, trees 380 million years ago, and humans 300,000 years ago.

Octopuses have three hearts!

One pumps oxygenated blood throughout the body, and two pump blood to the gills.

Space

Diagram comparing the tilt and rotation of Mars and Earth, showing their axes, equators, and rotation times. The diagram illustrates the planets' axial tilts, directions of rotation, and corresponding rotation times.

A day on Mars is about 40 minutes longer than a day on Earth, because Mars rotates slower on its axis!
