Dysprosium as a very high ability to absorb neutrons, this makes it really good for shielding in nuclear reactors, and it is also used to make lasers and lights. This is a general science zone, where we will meet five researchers from completely different areas of science. Thank you from your winner - James! If yo.

Holmium is a very silvery white solid metal with a variety of uses. Erbium oxide is pink and can be used to colour glass, which is often used in sunglasses and cheap jewelry. This is a general science zone, where we will meet five researchers from completely different areas of science.
