Until recently scientists have not been able to figure out the information coded in the folding of our DNA in the nucleus. A new map now makes this task simpler. This kind of map will not only tell us how the instructions in our DNA lead to making each one of us, but it may also provide new ways to understand and even treat diseases like cancer.
Until recently, you pretty much had to rely on family stories that were passed down through the generations to learn about your ancestors. But that is now set to change. With a little luck, a whole lot of science and genealogy, you may be able to use passed down DNA instead of stories to learn a bit about that great-great-great-grandfather.
Neanderthals may be extinct but at least 20-40% of their DNA lives on in modern Europeans and Asians because of interbreeding. Neanderthal DNA survives because it gave useful traits to the ancestors of Europeans and Asians.
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.
Imagine a world where your experiences can be passed on to the next generation. Scientists don’t yet know if this happens in people, but they have now confirmed in a new study that this sort of thing does happen in mice.
Ever since AIDS emerged as a deadly disease in the early 1980’s, scientists have been looking for a cure. And now, using a very precise set of DNA scissors, they may finally be taking baby steps towards one.
