Scientists can now make precise, specific changes in the DNA of primates using a new technology first identified in bacteria. Not only will this usher in an age where animal models for human diseases are more useful, but it also means that we are very close to being able to do the same thing in people.
Scientists have just done something that would have been unimaginable even a few years ago—they have sequenced the entire set of DNA from a 7000 year old Spaniard. And this isn’t all. They have also managed to learn that he was most likely a dark-skinned, blue or green-eyed man who had trouble digesting milk as an adult.
Six out of every thousand people are estimated to be identical twins. This means that there are a lot of children being fathered by identical twins and that these twins are involved in a good number of crimes too. And until recently, none could be identified from just their DNA. This has all changed in a new study where scientists were able to reliably use DNA to tell two identical twins from each other.
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.
In response to a letter from the FDA, a direct-to-consumer (DTC) genetic testing company in Mountain View, California called 23andMe has agreed to stop providing health data on new purchases of its $99 genetic tests.
Some men are unknowingly raising kids that are not biologically related to them, but until recently, the numbers were uncertain. Now that DNA testing is becoming cheaper and easier, better data has become available.
