Sciences, on the Team planet, are researched separately. This means that once a Team planet is created, Alliance members have to start researching sciences from scratch. Sciences researched on a Team planet are the ones that affect all aspects of the Team planet. Researches on the Team planet do not affect the players individual planets, fleets etc. in any way.
The standard sciences are available on the Team planet, but there is a diference regarding Additional sciences - all three Additional sciences can be researched (just one on a non-Team planet).
Note that the science Ecology is not available on Team planets as they are not affected by Ozone.
