Thanks to X-ray telescopes, scientists in the 1970s found the first real evidence that black holes actually existed, and astronomer Andrew Fabian has used X-ray research to unlock incredible mysteries ever since, including a giant sound...

Some of the most exciting phenomena in space can’t be seen from Earth because our atmosphere soaks up high-energy light. That’s why NASA built Chandra, the most powerful X-ray telescope ever launched, and the observatory has helped...

A lot of people react to certain compounds found in skincare products, and scientists may have figured out why these pesky rashes happen and how to prevent them. Meanwhile, a pair of papers published last week show how AI can be trained...

The human body is a complicated thing! To be able to move, fight off diseases, and even see colors, lots of different systems and organs need to work together. Squeaks' robot body is pretty complicated, too, so Jessi has put together a...

We find Miss Palomine at the exit of Alphabet Groceries. This begins a discussion of words that have an -X sound at the beginning, but that start with -E and then -X. She shows the Xx letter card, plays the Xavier X-ray music video, and...

Miss Palomine explains that there are very few words that start with -X. She tells the student that Xavier X-ray is very jumpy. Sometimes he jumps to the second letter of the word and sometimes he jumps all the way to the end of the...
