Last week, a federal judge ruled  that federally funded research on human embryonic stem cells (hESCs) is legal. The decision in Sherley v. Sebelius ends 11 months of uncertainty about whether hESC research supported by the National Institutes of Health (NIH) would suddenly be shut down. It also caps a decade of ups and downs  with stem cell policy that began on 9 August 2001 when President George W. Bush announced that NIH would fund research on hESCs--albeit only on existing cell lines.
Join us at 3 p.m. EDT on Thursday, 4 August, for a live chat to discuss what's next with Sherley v. Sebelius and what it's like to work in a research field where the rules are always changing. Feel free to leave questions in the box below before the chat begins.
