A group of scientists has replaced a natural chromosome in yeast with an artificial one. This won't only make a more useful yeast, but it also opens the door to redesigning the DNA of more complicated beasts like plants and animals (or us) and maybe even to resurrecting extinct species like the passenger pigeon or wooly mammoth.
If your annual checkup included a simple blood test to determine how much DNA damage you have in your body, you may be able to optimize your long-term health by taking action to minimize DNA damage due to your diet, exercise and environment. A startup company called Exogen Biotechnology wants to provide the public with a way to monitor their DNA health.
The FDA challenge may hurt the personal genetics industry in the short run. No traits, no health risks -- no fun. But the company is still allowed to show ancestry results. 23andMe's map of my distant relations offered a glimpse of the movement of people across the world. The more people who joined and shared their genomes, the more comprehensive a picture we could form of a global family tree. A day might come when I would know precisely how related I was to, for example -- you.
Parents can and do have children who look very different from themselves, but lack of understanding of genetics have led to authorities taking children away from them.
Scientists have struggled for a long time to explain why 85-90 percent of people are right-handed. They’ve known genetics plays an important role in people occasionally ending up left-handed, but they also know it is not the whole story.
A US Supreme Court ruling issued Thursday has big implications for Bay Area biotech companies and medical researchers, not to mention patients who want genetic testing or gene-based therapies. The Justices ruled that no one has the right to patent natural human genes, but synthetic DNA material can be patented.
