Biofuels Production Impacts

August 17, 2006 | Leave a Comment

Biofuels require subsidies. ‘Demand for biofuels will increase over the next 10 years, but producers will still depend on government support. Oil prices have seen a sustained increase since 2004, and consumer demand for biofuels is greater than before and is likely to accelerate in coming years, according to a report by the Organisation for [...]

Hydrogels: Biocompatible Adhesives in Cornea Transplants

August 8, 2006 | Leave a Comment

Hydrogels for Cornea Transplants. ‘In the July 19 edition of Bioconjugate Chemistry, Mark Grinstaff and his colleagues at Boston University and Duke University Medical Center describe a novel form of hydrogel that performed well enough in tests to suggest that it can reduce the number of sutures required in surgery. The team built on earlier [...]
