The shortage of human donor eggs has led to efforts to substitute animal oocytes. However, a new study demonstrates that animal oocytes lack the capacity to fully reprogram adult human cells.

A new study has discovered that genetic variation in an asexual insect -- insects that reproduce by cloning themselves -- is maintained by rare clones being chosen for the next generation, a phenomenon known as frequency-dependent selection.

In addition to size, tomatoes have been bred for shape, texture, flavor, shelf-life, and nutrient composition, but it has been difficult to study these traits in tomatoes, because many of them are the result of many genes acting together.

The cloning process resulted in small new larvae and original larvae that were substantially smaller.

The implications for disease treatment could be significant. Reprogramming adult stem cells into embryonic stem cells could generate a potentially limitless source of immune-compatible cells for tissue engineering and transplantation medicine. A patient's skin cells, for example, could be reprogrammed into embryonic stem cells. Those embryonic stem cells could then be prodded into becoming various cells types -- beta islet cells to treat diabetes, hematopoetic cells to create a new blood supply for a leukemia patient, motor neuron cells to treat Parkinson's disease.

Now, a new technique may allow scientists to create a melanoma vaccine able to stimulate helper T cells. The approach may also aid in the development of other vaccines against cancers or infectious diseases.
