Rising temperatures are fundamentally changing the way Australia's bearded lizards get their gender. Basically, the lizard's sex is not dependent on their genes as before, but on temperature. In time, the male chromosome could disappear, as more and more females are bred - the preferred sex. What this means is that if temperatures reach a critical level, then the lizards could become extinct due to lack of males. This has never happened before and it's as scary, as it is interesting.
The X-Shape in which we usually see chromosomes depicted in is only a snapshot of their real complexity – a new method for visualizing them showed. A joint project involving the Babraham Institute, the University of Cambridge and the Weizmann Institute has produced the most beautiful and accurate models of chromosomes available up to date. […]
The insertion of one gene can shut down the extra chromosome which causes Down Syndrome, according to a study published today in Nature. A dreadful disease Down Syndrome (DS), also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It’s the […]
Researchers at Duke University studied the telomeres – the tip of chromosomes that protect them – in a group of children and found that those who had experienced trauma had their telomeres shorter than those that hadn’t. These chromosome tips, which can be viewed akin to shoelace tips, have been linked by scientists with aging […]
Good news for men, and especially women: the Y chromosome, which holds the male sex determining genes in most mammals, including humans, is not going extinct, as some claim, as a new research found that the diminishing gene numbers have come to a halt and will remain this way. Sex chromosomes come in pairs, such […]
