DNA Scissors for genetic surgery?

A story started circulating last week focusing on zinc finger nucleases. These are enzymes that cut DNA in a very specific way, allowing for a new, different means of altering genes in vitro and possibly in vivo. Genetic treatments are the exciting future medicine we all hope for, especially with the genetic disorders that are inborn and uncorrectable otherwise. The ability to correct disorders by correcting the body at the genes is exciting, so this story generates lots of interest. Read it yourself here.

The first of many…

I mentioned in an earlier post that I’d been stockpiling articles and posts for daily uploads. This is the first of those, but before I get into that, I want to share where many of these are coming from, because that is, by itself, an incredibly useful professional tool.

Recently (between starting the blog and restarting the blog), I joined/became more active on LinkedIn. I found groups there, including groups by interest. Among them are microbiology & immunology groups, and many of the links I will be sharing were discovered when they showed up in my inbox via a LinkedIn group!

This may well be old news to many of you, but I didn’t want anyone to overlook useful tools. Finally, remember: employers look at all online and social media when hiring, so be mindful of what you post (or what your friends may be able to post).

Now, with no further ado: A video on how the flu invades the human body. Because light microscopy can’t capture viruses, this is an animation, but it is very well done and has explanation with it.


US Supreme Court Says Human Genes Can’t Be Patented

In a demonstration of just how deeply entrenched science and medicine are in our everyday lives, an article in the Wall Street Journal today announced an important decision from the US Supreme Court: Human Genes cannot be patented.

This has been hotly contested: those arguing for patent have argued that the research and development done with the genes is costly, and without the protection of patents, it is likely to go unfunded. Those arguing against patent have pointed out the flaw of patenting a gene carried by millions of people (or even just a few), and worse, the trouble that is caused when a carrier of a gene seeks treatment for their condition, only to find out their own genetic code is locked under patent protection.

I, personally, am an advocate of openness and freedom. I believe that keeping medical research like this locked under patent is absurd, and often hinders advancements in treatment. I will note, however, that I am not currently employed by any researchers, and thus I am not bound by any such privacy agreements myself. I can understand if a scientist’s work and livelihood is dependent on funding and thus on signing privacy agreements. I may find them absurd, but at the end of the day, pragmatism still has its place.

Still, I think this was a victory for the open exchange of ideas. What do you think? Will this be a boon to medicine? Should it have ever been in question?
