- Deactivating protein may protect nerve fibers in MS
04-23-2007 · EurekAlert!
Oregon Health & Science University neuroscientists are eyeing a protein as a potential therapeutic target for multiple sclerosis because de-activating it protects nerve fibers from damage. OHSU researchers have shown that genetically inactivating a protein called cyclophilin D can protect nerve fibers in a mouse model of multiple sclerosis. Cyclophin D is a key regulator of molecular processes in the nerve cell's powerhouse, the mitochondrion, and can participate in nerve fiber death.

- Nanoengineers mine tiny diamonds for drug delivery
10-12-2007 · EurekAlert!
Northwestern University researchers have shown that nanodiamonds are very effective at delivering chemotherapy drugs to cells without the negative effects associated with current drug delivery agents. Their study is the first to demonstrate the use of nanodiamonds, a new class of nanomaterials, in biomedicine. In addition to delivering cancer drugs, the model could be used for other applications, such as fighting tuberculosis or viral infections, say the researchers.

- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Comprehensive model is first to map protein folding at atomic level
11-06-2006 · EurekAlert!
Scientists at Harvard University have developed a computer model that, for the first time, can fully map and predict how small proteins fold into three-dimensional, biologically active shapes. The work could help researchers better understand the abnormal protein aggregation underlying some devastating diseases, as well as how natural proteins evolved and how proteins recognize correct biochemical partners within living cells.

- First impressions: Computer model behaves like humans on visual categorization task
04-02-2007 · EurekAlert!
In a new MIT study, a computer model designed to mimic how the brain itself processes visual information performs as well as humans do on rapid categorization tasks. This study supports the hypothesis that rapid categorization happens without feedback from cognitive or other areas of the brain. The results also indicate that the model can help neuroscientists make predictions and drive new experiments to explore brain mechanisms involved in human visual perception, cognition and behavior.

- Mice stressed in simulated weightlessness show organ atrophy
09-03-2007 · EurekAlert!
A ground-based, experimental model used to simulate astronaut weightlessness in space has provided Rutgers scientists an opportunity to study the effects of stress on immune organs. The new study demonstrated that osteopontin is required for the atrophy of immune organs brought on by the stress resulting from hindlimb unloading.
