Scientists Develop Sound Wave FACS Technology

Researchers from Singapore have developed a highly precise single-cell sorting alternative to the popular FACS that uses focused sound waves instead of harsher electric fields. Their detection mechanism also shrinks the instrument size, reduces its complexity and substantially lessens costs. In addition, it enables more accurate cell  sorting and leaves no damage to target cells.

Dramatic Decline in Sperm Counts of Western Men

Sperm concentration among men from Western countries declined by more than 50 percent in less than 40 years. There is a large decrease in sperm quality among men from North America, Europe, Australia, and New Zealand a study reports. The even more disturbing fact is that the decline doesn’t seem to be leveling off. If it continues or possibly even increases among men living in these countries, this will be a major problem for fertility and reproduction.
