Researchers at the Wyss Institute have developed nano-machines made out of DNA that can be programmed to deliver its payload to targeted cells. The payload can be specific molecules, proteins, or antibodies which deliver a message to receptor proteins on the surface of the cell.
For example:
“Douglas and Bachelet used this system to deliver instructions, which were encoded in antibody fragments, to two different types of cancer cells — leukemia and lymphoma. In each case, the message to the cell was to activate its ‘suicide switch’ — a standard feature that allows aging or abnormal cells to be eliminated. And since leukemia and lymphoma cells speak different languages, the messages were written in different antibody combinations.”
Watch this short video and go to the original article for more information about this potentially groundbreaking work.

What if a 75 year old could walk like a 25 year old? That question is what starts off this video about research that is going on at the Wyss Institute. James Collins, whom many of you might recognize as one of Boston University's best professors, is one of the leaders of this research. As people age, they lose their sense of proprioception which helps them balance. In fact, falling is the leading cause of death from injury among people older than 65 years old. Through the phenomenon of stochastic resonance, the balance of the elderly can be significantly enhanced, and has the potential to affect many people suffering from balance deficiencies.
For more information read this paper explaining the concept further. (BU login required) Noise Enhanced Balance Control

As Raphael mentioned in the first post, we would like to post articles, news, and links that we think might be of interest to Biomedical Engineers. Here's the first one!
This is an interesting article recently published in Biomacromolecules about controlling the delivery of cancer drugs (may require a BU login): http://pubs.acs.org/doi/abs/10.1021/bm2009125
Happy reading!
Natalia Vieira, Secretary 2011-2012
