...Holzman: When it comes to introducing proteins into a human being, doctors have two options: You can infuse them into the brain (which requires a permanent pump), or you can choose gene therapy, as in this procedure. Gene therapy means you implant genetically modified tissue during a one-time procedure. Hopefully, those cells will produce the factor you are looking...

...device developed at the University of Strasbourg. The Tactile Vision Substitution System (TVSS), a 3-sq cm pad that rests on the tongue, translates images from a digital camera into electrical stimulation, which forms patterns on the tongue corresponding to the shape of the image. The team wants to implant the tvss in a dental retainer that sends signals to a digital camera mounted on a pair of glasses...

...fact, the risks involved with cloning mammals are so great that Wilmut, the premier cloner, calls it "criminally irresponsible" for scientists to be experimenting on humans today. Even after four years of practice with animal cloning, the failure rate is still overwhelming: 98% of embryos never implant or die off during gestation or soon after birth. Animals that survive can be nearly twice as big at birth as is normal, or have extra-large organs or heart trouble or poor immune systems. Dolly's "mother" was six years old when she was cloned. That may explain why Dolly's cells...

BREASTS Back in 1992, NIH scientists were asked by Congress to study the safety of silicone breast implants. The first part of their investigation, completed in November, studied breast-cancer rates in 13,500 women who had breast implants (most of them silicone) and 4,000 who did not. Results: the implant patients showed no added risk for breast cancer when compared with the controls. Researchers warn, however, that further studies are needed to determine whether the implants are linked to other cancers or connective-tissue disorders...
