Artificial prions created

Scientists have identified amino acid sequences that allow prions to aggregate and replicate, leading to the creation of an artificial yeast prion. This breakthrough sheds light on the mechanisms behind diseases like mad cow disease and Alzheimer's, potentially paving the way for new treatments.

Tissue cells can revert to stem cells

Researchers have discovered that tissue cells in clusters of 4 and 8 can revert to a stem-cell state under specific conditions, working just as well as normal stem cells. This finding could provide a new approach for harnessing differentiated cells to enhance tissue repair, similar to animals that can regenerate lost parts.

Stem cell death gives clue to brain cell survival

Researchers at UGA have identified a lipid-protein duo causing massive stem cell death during brain development, but also hinting at potential recovery mechanisms for devastating diseases like Alzheimer's and Parkinson's. The study reveals that this 'deadly couple' leads to the survival of cells destined to form neurons.
