Synthetic biology -- the emerging science of creating genomes, cellular components and even whole cellular organisms from scratch -- confronts regulators with some tricky problems.
Global climate models are missing a good chunk of plant information that could significantly alter long-term climate change predictions. A new technique for modeling phytoplankton -- microscopic plants in the upper layers of the Earth's waters -- could reveal a much more accurate picture.
A survey of recent studies and projects to bridge the nanotechnology regulatory gap in the developing world.
