To attract more people to

What do those mean ?

To let more people to what is iGEM & synthetic biology

know

To make people iGEM &synthetic biology interested in

To let some of those people who start to realize iGEM &synthetic biology to us!! join

engage in synthetic biology field!

Achievements We have submitted 11 parts to part registry.

We have characterized and proved that these new biobrick parts:

SQR, CysI, DsrI really work as our expectation.

We have modified BBa_K299812 (INV+LLO) and elevated our

idea to a higher level, to create venusian!

We have held a meet-up with Taiwan iGEMers, with board

games, iGEM songs, movies and coorperated with NTU-

Taida.

We have already outlined and detailed an extremely new human

practice - outer space human practice project (New human

practice approaches!!).
