" Cell Gels " -- The Discovery Files
University of Delaware scientists have developed a novel biomaterial that offers great promise for helping to repair and regenerate human tissue. Their hydrogel invention -- which has surprising antibacterial properties -- could be injected into a wound, where it rigidifies nearly on contact. This opens the door to possibly delivering a targeted payload of cells and antibiotics to repair damaged tissue -- offering a myriad of uses including regenerating healthy tissue in a cancer-ridden liver or healing a biopsy site.

Organ Donation: Opportunities for Action
Rates of organ donation lag far behind the increasing need. At the start of 2006, more than 90,000 people were waiting to receive a solid organ (kidney, liver, lung, pancreas, heart, or intestine). Organ Donation examines a wide range of proposals to increase organ donation, including policies that presume consent for donation as well as the use of financial incentives such as direct payments, coverage of funeral expenses, and charitable contributions.
