| Frogs, foam and fuel: University of Cincinnati researchers convert solar energy to sugars Tue, 16 Mar 2010 00:00:00 EDT |
(University of Cincinnati) In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant -- like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that. |
| 3-D cell culture: Making cells feel right at home Mon, 15 Mar 2010 00:00:00 EDT |

Scientists from Rice University and the University of Texas M.D. Anderson Cancer Center have found a simple way to suspend cells in magnetic fields so they grow into three-dimensional cell cultures. Compared with flat cell cultures, the 3-D cell cultures more closely resemble real tissues from the body and should provide more realistic targets for testing new drugs. |
