Scientist seem to be on their way to stops certain pathogens from causing as much damage as they normal do. They have succeed in stopping MRSA (a form of the flesh eating bacteria) in lab mice. MRSA is a antibiotic (or some of it's strains are) resistant. This is a new technique that they are hoping to develop could help fight these other wise incurable disease. MRSA is responsible for more deaths then AIDS every year and scientist and doctors are desperate to find a way to fight this "super bug" and they might have just found their answer. The RNA of the bacteria is what controls each strain and scientist have found away that renders it unable to reproduce new RNA. This molecule is called RNPA1000 and seems to stop MRSA.
I think that this is by far one of the most interesting things I've heard about in a long time. I have been interested in MRSA and other forms of the flesh eating bacteria for a few years now. I strongly support these scientist in their research. With bacteria like MRSA on the rise and virtually unstoppable it would be life saving to be able to stop it. I highly hope that their research proceeds to a point that they can test this new theory on humans. We maybe on our way to curing a super bug and possible other antibiotic resistant strains as well.

A New Species of Wolf is Dicovered in Africa
The article reviewed in this current event can be found here.
Information:
The "Egyptian Jackal", which was commonly confused with the golden jackal has now been proved to be related to the Holarctic grey wolf, the Indian wolf, as well as the Himalayan wolf. Genetically similar specimens to the new species were found in Ethiopia, which is a good 2,500 kilometers away. This astonishing news could mean that the species is not only found in Egypt, suggesting that there is a possibility that this wolf can be found between Egypt and Ethiopia. Many biological questions are rising up, questioning how this wolf evolved and lived alongside golden jackals, and Ethiopian wolves.
Opinion:
As for my opinion, I am alongside these scientists who are questioning how this news species evolved to live alongside this relatively different species of wolf, and the very different species of jackal. I'm ecstatic that that a new species of wolf has been discovered. I'm also surprised that this species has been living under our nose all this time, and we never even noticed. I'm hoping more biological discoveries, such as this one, can be found in the near future.

Bacteria In Your Stomach Helping Your Brain?
http://www.sciencedaily.com/releases/2011/02/110201083928.htm
According to a new study done the bacteria found in your stomach may help brain development and play a key role in your body's ability to function. To test this theory a group of scientist used lab mice. They found that the mice with out the bacteria weren't as safe and did more dangerous things then the ones with it. In humans after birth there is a critical time during brain development that these bacteria are need to help regulate the other hormones and help balance. As of right now though the only thing certain on adults (not babies) are on mice. Human's haven't yet be tested.
I'm honestly not surprised that these 'germs' are connect to brain development. The right bacteria have always been found to be important in bodily functions. One of the main uses in the intestines and stomach. The body is a complex serious of systems constantly working together; even without our knowledge. Evolution has made it so that there are checks and balances for all these "problems" our body faces everyday can be taken care of (for the most part). I think it is cool that we are learning more about these bacteria and the important roles they play, because the more that we know about our bodies, the more likely were are to be able to fix them.
I really do hope that these studies prevail and humans can be tested soon.
