Evidence from various sciences reveals that there are diverse ways of being male, female, or both. An anthropologist argues that embracing these truths will help humans flourish.
Chromosome Analysis Goes High Tech
Ricki Lewis | Oct 15, 1989 | 5 min read
Since the 1 920s, when researchers began to study chromosomes, the analysis of human chromosomes has presented a particularly tough technological challenge, simply because there are so many of them. When displayed under a light microscope. the strands of human genetic material tend to bunch together maddeningly, overlapping and intertwining like so much spaghetti. For these reasons, it wasn’t until 1956 that the correct number of 46 human chromosomes (23 pairs) was clearly demonstrated.

Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.
Human Clinical Trials Begin For Cervical Cancer Vaccines
Steve Bunk | Oct 26, 1997 | 6 min read
Efforts are under way to develop a vaccine against one of the world's deadliest illnesses, cervical cancer. Along with a number of university research laboratories, at least a half-dozen biotechnology and pharmaceutical companies are beginning clinical trials or are in preclinical development of such drugs. Efficacy in humans remains to be firmly established, but if the vaccines progress to later-phase trials, challenging jobs for immunologists, microbiologists, and biochemists will multiply. "
