conference info

[santha at vigyan.iisc.ernet.in]

Can anyone tell me how i could get information o all the
conferences that are being organise d in the area of 
biosciences, the dates scheduled , location contact addresss
etc. I would need this information so i could send out 
posters to these conferences/meetings/symposia
to advertise for a conference that we are organising

the information source should be a fairly active one that keeps
updating the news.
thanks
