Lightweight Radiation-proof Fabric?
kramer writes "New Scientist is reporting the creation of a lighweight radiation-proof fabric called Demron. Demron is being touted by its inventors as comparable to lead shielding at a fraction of the weight. Could be very useful for any future interplanetary space missions where the amount of radiation absorbed by the crew is a significant concern."

Ummm... heavier stuff requires more energy to get it off Earth into space, so yes, weight is an issue.
