We kick off by looking at some Halloween staples through a scientific lens (sort of)…<\/p>\n
- \n
- \u00a0In an attempt to get into this year\u2019s Famous Scientists\u2019 Halloween Ball, I dressed up as, logically enough, a famous scientist in order to blend in. I made myself up to look like a handsome man (there was a lot of make-up involved) from the early 19th<\/sup> century, and I carried with me some of my discoveries, including sodium, potassium and magnesium, and my most famous invention, a safety lamp in which the flame is enclosed inside a mesh screen. Who did I dress up as?<\/li>\n
- As well as being excellent for carving into scary or amusing faces, another important attribute of pumpkins is that they are monoecious. What does monoecious mean?<\/li>\n
- You are in attendance at a Halloween bonfire and find a bit of metal on the ground. You toss it onto the fire, and it burns with a bright red flame. What metal could this have been?<\/li>\n<\/ol>\n
Round 2 – Blood and Gore<\/span><\/h3>\n
- \n
- Human blood gets its red colour from hemoglobin, which contains iron. Many molluscs and arthropods have blue blood because their blood instead contains hemocyanin – which instead of iron contains which other metal?<\/li>\n
- People with which human blood group are known as universal donors? And which blood group is possessed by universal receivers?<\/li>\n
- What is the name of the Oscar-winning 2006 documentary about global warning that was written and presented by former US vice president Al Gore?<\/li>\n<\/ol>\n

Pictures this week come from the aforementioned Famous Scientists\u2019 Halloween Ball. We dispatched a paparazzo to take some pictures of famous scientists in fancy dress as they entered the party. Can you see through their cunning disguises and identify the scientists in the pictures below?<\/p>\n
