Is alcoholism genetic? How can you know your susceptibility.

Alcoholism affects many people. It is a serious issue and it can be observed all over the world. As with any other phenomenon like alcoholism that affects thousands, there can be several patterns pointing at the source of the problem. A recent study found such a pattern, specifically a polymorphism in a gene that affects an individual's susceptibility to alcoholism.

In several patients brains, researchers found that there are increased human herpesvirus 6A (HHV-6A) and herpesvirus 7 (HHV-7) compared with controls. Since increased viral DNA was found in patients compared to controls, there may indeed be a connection there.

What does junk DNA do?

DNA is very complex and we are still learning a lot every day about how it works. It is a line of code, but instead of 1 and 0 like in binary it has four letters, A, T, G and C. Not really letters, they are small pieces that make up DNA, a molecule. So,… Continue reading What does junk DNA do?

If you add the fact that in some cases due to convenience people tend to consume such foods twice or more within a single say, you end up with some consequences.

CRISPR Cas9 causing tumours in mice… But its actually good.

CRISPR-Cas9 is a very useful tool for gene editing. It allows us to precisely and inexpensively edit an organism's genes. You can read more about it here. A recent study used it for something different though with great results. Instead of attempting to treat tumours in mice with this technology, hoping that someday this therapy… Continue reading CRISPR Cas9 causing tumours in mice… But its actually good.
