Tiny scaffolding allows stem cells to become working fat cells

...entional cell cultures, cells usually grow as flat deposits bathed in growth medium. While useful, these "two-dimensional" patches fail to mimic all the tasks performed by cells in vivo. Specific genes, proteins and hormones normally produced by healthy cells are often absent in two-dimensional colonies. "Th...

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

To understand the formation of the brain-clogging deposits that cause such disorders as Alzheimer's and Parkinson's diseases, Duke University chemists have figured out how to capture and "micromanipulate" the single molecular building blocks of the deposits. Their aim is to understand the detailed assembly ...

Scientists identify molecular events that drive cell senescence

Amyloid protein deposits are present in the early phaseof the disease - a fact that suggests a gene vaccination would be astep forward in slowing the progression of dementia.From the mouse studies and in previous clinical trials of patients withAlzheimer's disease, immunizat...

New Clues Add 40,000 Years to Age of Human Species

...of the world. “The correlation between the Kibish deposits and the Mediterranean sapropels not only helps us resolve an anthropological mystery, but it provides a whole new perspective on the history of the Turkana Basin, a setting that has provided so much important evidence regarding human evolution,?says...
