Magnetic Yeast - Yeast cells aren’t normally magnetic, but a little genetic engineering can make them thralls to a magnetic field. The research, published in PLoS Biology, suggests that manipulations of a few widely expressed genes could be enough to get any cell magnetized, which could be a powerful tool for both research and medicine.
