From EcoGeek via Grist comes word of a nifty new birth control method for men:
The remote control, implanted device will allow users to 'press pause' on their sperm. (although it doesn't mention whether a 'rewind' function is in the works). The device has been developed by Australian scientists, and could herald a new dawn of even more convenient contraception for men, which has the potential to keep population growth under control more effectively.
Which of course raises the age-old question: Who controls the remote?
