Just as Dante found it easier to conjure the pains of Hell than to evoke the joys of Heaven, so too do bioethicists find it easier to concoct the possible perils of a biotech-nanotech-infotech future than to appreciate how enhancements will contribute to flourishing lives. One of the chief goals of this symposium is to think about the indispensable role that virtue plays in human life. The chief motivating concern seems to be the fear that biotechnologies and other human enhancement technologies will somehow undermine human virtue. As we will see, far from undermining virtue, biotech, nanotech, and infotech enhancements will tend to support virtue; that is, they will help enable people to be actually good.

"I am Your Body"

Jane Pratt (formerly of Sassy Magazine and her eponymous Jane,) launched a website for women: xojane, earlier this year. Last week the site's Health and Beauty Director wrote a blog post explaining that she never uses condoms, birth control pills, or other contraception (for fear of becoming fat) and instead relies on the emergency contraceptive Plan B to prevent pregnancy. And a segment of the internet exploded. (Her responses to some of the comments seem a bit clueless for someone with her title.) Critics have noted that the post was filled with "ignorant" "inaccuracies and misconceptions" about womens' health, sex, Plan B and other forms of birth control. [more inside]

Gamers solve molecular puzzle that baffled scientists. The structure of a protein causing AIDS in rhesus monkeys had not been discovered in 15 years of attempts. Players of a videogame did it in ten days. Foldit, the game in question. Abstract. Previously, previously.

The Triumph of New-Age Medicine "Medicine has long decried acupuncture, homeopathy, and the like as dangerous nonsense that preys on the gullible. Again and again, carefully controlled studies have shown alternative medicine to work no better than a placebo. But now many doctors admit that alternative medicine often seems to do a better job of making patients well, and at a much lower cost, than mainstream care—and they’re trying to learn from it."

"It is only fitting that the story of the brain should be a visual one, for the visuals had the ancients fooled for millenniums. The brain was so ugly that they assumed the mind must lie elsewhere. Now those same skeletal silhouettes glow plump and brightly colored, courtesy of a variety of inserted genes encoding fluorescent molecules. A glossy new art book, “Portraits of the Mind,” hopes to draw the general reader into neuroscience with the sheer beauty of its images."

Using a 3-D petri dish, Researchers at Brown University and Women & Infants Hospital of Rhode Island have built a completely functional artificial human ovary that will allow doctors to harvest immature human egg cells (oocytes) and grow them into mature, ready-to-be-fertilized human eggs outside the body. (In vitro) The advance could eventually help preserve fertility for women facing chemotherapy or other medical treatments that may be destructive to ovarian folliculogenesis. Press Release.

Followup to this post: A US District Court has ruled that Myriad Genetic's patents on breast cancer genes BRCA1 and BRCA2, which allow them to hold exclusive rights to a widely used genetic test for inherited breast and ovarian cancer susceptibility, are invalid. Genomics Law Report analyzes the ruling in two posts. The decision is likely to be challenged in a legal appeal — but if upheld, it could have huge implications for the biotechnology industry.

Cracking the Cancer Code: We already know that all cancers are caused by DNA mutations acquired during a person's lifetime. But what mutations actually cause cancer? We may be one step closer to finding out. International research teams led by the Cancer Genome Project at the Wellcome Trust Sanger Institute have now mapped the entire genetic code of two of the most common human cancers: lung and skin (malignant melanoma). Their findings have the potential to revolutionize preventative and treatment therapies as well as pave the way for new early detection tests. More. [more inside]

On behalf of medical organizations, universities, & individual patients, pathologists and genetics researchers, the ACLU has filed a lawsuit against Utah-based Myriad Genetics and the US Patent and Trademark Office. Myriad holds the US patents to the BRCA1 and BRCA2 genes, associated with hereditary causes of breast and ovarian cancers. Their patents guarantee the company the right to prevent anyone else from testing or studying those genes, which the ACLU says is unconstitutional and inhibits researchers from finding treatments and cures.

Historical anatomy models were a marriage of art and science. From about the 13th to the 19th centuries, exquisite wax models were the state of the art. Florence's La Specola anatomical wax museum houses the works of master artists, such as Ercole Lelli, Anna Morandi, and Clemente Susini. The later years of wax models tended towards the grotesque: moulage and depictions of pathological conditions and physical anomalies. Due to the labor required and delicacy of wax models, papier-mâché became the favored production method in the 19th century, partly due to the ability to dissect the models. Over time, models became more stylized to protect the delicate sensibilities of the public. Today, models are again shocking the public with extreme realism.
