How many types of cells are there in the human body? Textbooks say a couple of hundred. But the true number is undoubtedly far larger. Piece by piece, a new, more detailed catalogue of cell types is emerging from labs like that of Aviv Regev at the Broad Institute, in Cambridge, Massachusetts, which are applying recent advances in single-cell genomics …
-Easter week in Latin America (called Semana Santa) can be a truly crazy and some say, nerve wracking experience for gringos and expats. Here’s why….

But don’t assume. Don’t assume anything! Just try not to laugh… that would be rude.
Scientists at the University of California, Berkeley, have identified a new molecular pathway critical to aging, and confirmed that the process can be manipulated to help make old blood like new again. The researchers found that blood stem cells’ ability to repair damage caused by inappropriate protein folding in the mitochondria, a cell’s energy station, is critical to their survival …
