We’re now on day three of the Nature Network Easter Egg hunt.

To briefly recap, we’ve hidden short amino-acid sequences from a well-known egg protein throughout the Network and associated sites. You have to solve 20 clues (four each day this week) to their location. The clues are given out via our Twitter feed.

The competition is open till next Monday, so you can begin your egg hunt at any point until then. If you’re coming late to this, here are the clues so far:

Monday

1. Easy one to start. Simply find the Easter egg forum for more info and a place to discuss the challenge.

2. I am the Egg Man, but I’m profiled under my other name.

3. Look where you might eggspect to see an announcement

4. Find the forum post about the world’s oldest bunny and you’ll get the next sequence.

Tuesday

5. Don’t (London) dinosaurs lay eggs? Better take a picture of that!

6. Or better yet…isn’t there a blog about a fossilised nest of eggs, and a serpentine intruder?

7. Easter lambs seem to be hidden in the Gulf Stream.

8. Our blogger Dekker muses on Wordsworth’s seasonal flower

Wednesday (day of the puns)

9. Hennifer Rohn wonders if GM chickens might lay chocolate eggs

Solve the clues, find the sequences, then email them to network@nature.com by the end of Monday. The one with the most correct answers wins an electronic subscription to Nature.
