to change. things have changed so much. a big change also this morning, people responding to headlines, there might be a game changer and how the medical community treats hiv using umbilical cord blood. talk about that. this is scientifically really fascinating. it is not going to be a change for most people with hiv, but still fascinating. there was this woman in the united states, she had hiv and then afterwards she was diagnosed with leukemia and doctors needed to do a stem cell transplant. they intentionally sought out umbilical cord cells from a newborn who had a particular genetic variation that made them resistant to hiv. they sought that out intentionally. they gave her that transplant, and four years later, she is cured of hiv. it is just amazing. she s the third person this has happened to, it is still significant because what is interesting is this woman, unlike the other two, did not get something called graph versus host disease, which is a terrible complication of a t
well, i think the angle here, there s really two aspects to it for our particular patient as you noted identified as being mixed race. the cells that are resistant to hiv, natural genetic variation that occurs in probably less than 1% of people, and primarily people of northern european ancestry, when someone needs a transplant like this, they need to be matched with the donor cells, and because of that, it could be, you know, much more difficult for somebody who is not of european ancestry. but because we use umbilical cells, they don t need to be matched as vigorously, and broaden the possibility of having donor cells from umbilical chords that contain this variation. the other important angle is people of color are disproportionately affected by hiv in this country, and the majority of people living with
For years, researchers have been delving deep into the genetic origins of the Scandinavian gray wolves. They discovered that between 10% and 25% of the actual genetic variation are lost after five generations of inbreeding. It's well known that inbreeding is bad for animals and can lead to the extinction of endangered species.
If the pockmarks on the moon showed this kind of specific array surrounding each crater, we would think someone was using the moon for target practice.
University of Iowa announced that its Department of Biology scientists discovered a new type of genetic variation in yeast that can improve the production of ethanol. According to the study conducted by the University’s biologists, yeast strains with certain alleles of gene MED15.
