Scientists grow new lungs using 'skeletons' of old ones (June 28, 2010) -- Tissue engineers' progress toward growing new lungs for transplantation or research has long been frustrated by the problem of coaxing stem cells to develop into the varied cell types that populate different locations in the lung. Now, researchers have found a possible solution by seeding mouse embryonic stem cells into "acellular" rat lungs -- organs whose original cells have been destroyed, leaving behind empty, lung-shaped scaffolds of structural proteins. ... > full storySame types of cell respond differently to stimulus, study shows (June 28, 2010) -- Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, researchers have uncovered a much larger spectrum of differences between each cell than ever seen before. ... > full story
Carbon sequestration: Boon or burden? (June 28, 2010) -- The idea to sequester carbon is gaining support as a way to avoid global warming.
