One of the basic tenents of Biology is that DNA, found in the nucleus of every cell, is translated by RNA and codes for proteins that build and carry out the functions of life. In this video (brought to me by LinkedIn) you can see it happen via animation. http://www.youtube.com/watch?v=9kOGOY7vthk
It's the title of a science fiction horror film, but it's also a real occurrence for certain insects. In this video (another LinkedIn find) from the BBC, we meet cordyceps, a fungal infection that controls and eventually kills ants. This is a 3 minute clip from the longer Planet Earth series. If you've never seen this remarkable series, I highly recommend it. Not only do I enjoy it, I've found that even my pets enjoy it, too (yeah, I know, that's silly).
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.
