Supporters of a bill to curtail invasive research on chimpanzees aim to bring it to a vote in the US Senate shortly, reports the Nature News Blog.
The bill includes changes from an earlier version, namely to lengthen the timeframe to bring such research to an end and allow the research animals to remain in lab housing if sanctuary space is not available, but the Nature News Blog says the "heart of the bill — banning invasive research on great apes, whether publicly or privately funded — remains the same, and animal research supporters are still actively opposing it."
