The bloody-red shrimp was discovered in the lake near Superior, making it the last of the Great Lakes where the species has been found.

Anything scientists learn about regeneration by studying a relatively simple creature, like a planarian, can hold important clues.

When we look up to the sky, we see all the blue light that’s been scattered by the oxygen and nitrogen in our atmosphere.

There’s not a simple rule in identifying edible mushrooms. You need to know the thing that you’re holding and give it a name, and then you can understand if it’s edible or not.

Each molecule has a different size, so that determines how many would fit in a cubic inch of space.

For decades, scientists and physicians have believed that the appendix really doesn’t have a function in human beings.

Structurally joints don’t bend both ways because there are physical components within their design that prevent or resist motion.

Beetles and other insects can use camouflage for a number of different reasons. The biggest reason is to avoid predators and keep them at bay.

Hurricanes need some critical components to develop. They need a lot of water, and they also form near the tropics because they need a lot of sunlight.

To learn from a virtual body, it would need to be able to accurately simulate or predict how the body responds to internal and external changes.

Some species are simply more rare than others and don’t occur in very large numbers. But usually there is some factor that has driven a population to even greater rarity.

Stars such as our sun are formed in very large dark clouds. These dark clouds are molecular clouds made primarily of hydrogen and carbon monoxide.

The trigger for why leaves change color in the fall is day length, or more exactly the length of nights.

One reason the moon has craters is because it gets hit by objects from space. It also has craters because in its past it had volcanoes, and volcanoes can create craters.

Gelatin is the basis of what makes a gummy bear a gummy bear, but it starts with sugar, corn syrup and water.

Milk can make many products because of its complex chemistry and history.

In order for your brain to think, you need nerve cells that can detect information about the outside world and can transmit that information to other nerve cells.

We could send humans to Mars whenever we want. We have the technology to do it today, though we would need to build new rockets that use that technology.

Fireflies have a particular chemical called luciferin. In the presence of certain other compounds and chemical elements, it produces a glowing light.

Before the last glaciation, which started about 30,000 years ago, there was a deep river valley that ran under where Lake Mendota and the other Madison lakes are now.

How birds evolved from dinosaurs is a dinosaur paleontology question that extends all the way back to the late 1800s.

Learning as much as possible about works of art, whether it be an oil painting or sculpture or textile, can help conservators determine the best ways to protect and preserve these historical objects.

There are many, many objects beyond Pluto, but where they came from and when they formed is a whole other question.
