Facebook's New Chat Feature
Hey all,
I am so excited to see what Facebook is doing next. Now, Facebook has made it easy to find old friends, to chat with them, to schedule events with them. Facebook has allowed developers to build applications to Facebook. This allows user to continue to have fun with Facebook and not get bored with it. Facebook, in my mind, is going to surpass My Space. Facebook has released a new application to their core of Facebook. It's Facebook Chat. Yes, yes, I know! My Space has it's own chat, but facebook has made it better. How, you ask? You don't have to download another Chat application, like My Space. You can chat within your internet browser. My opinion Facebook couldn't have had a better idea. You already have all your friends on Facebook. There is no need to build up another buddy list. No need to have another program running in the background, just have Facebook up and you are good to go.

UCR’s Researchers Discover New Way to Store Information Via DNA
Technique may make it less expensive for industry to identify counterfeit merchandise
(February 19, 2008)
RIVERSIDE, Calif. (www.ucr.edu) – Researchers at UC Riverside have found a way to get into your body and your bloodstream. No, they’re not spiritual gurus or B-movie mad scientists. Nathaniel G. Portney, Yonghui Wu, Stefano Lonardi, and Mihri Ozkan from UCR’s departments of Bioengineering, Computer Science and Engineering, Biochemistry, and Electrical Engineering, and the Center for Nanoscale Science and Engineering, are just talented when it comes to manipulating DNA.
In their paper, “Length-based Encoding of Binary Data in DNA,” which was published by the American Chemical Society last month, the researchers discovered a system to encode digital information within DNA. This method relies on the length of the fragments obtained by the partial restriction digest rather than the actual content of the nucleotide sequence. As a result, the technology eliminates the need to use expensive sequencing machinery.
Why is this discovery important? The human genome consists of the equivalent of approximately 750 megabytes of data – a significant amount of storage space. However, only about three percent of DNA goes into composing the more than 22,000 genes that make us what we are. The remaining 97 percent leaves plenty of room to encode information in a genome, allowing the information to be preserved and replicated in perpetuity.
Given the size of the DNA fragments (one base pair of DNA is 0.33 nanometers), one could store a large amount of information in a very small space. By storing messages within DNA, organizations can “tag” objects to verify authenticity, as well as to inconspicuously send data to a specific destination. “Already there are several companies using DNA to tag objects that they certify to be original and which then can be very difficult to counterfeit,” says Stefano Lonardi, Associate Professor of Computer Science & Engineering at UCR’s Bourns College of Engineering.
For example, the British company, Redweb Security, has developed something called i-powder that tags DNA and another company called PSA DNA Authentication services tags sports memorabilia.
“What we developed at UCR is a method to encode a message in DNA in a way that does not require an expensive sequencing machine,” notes Lonardi. “The decoding still requires a wet lab procedure, but the experimental procedure is significantly easier.”

Introducing Nanoscope
The iPod Nano screen is too small.
Several pints changed hands, a Dremel was involved, and some small speakers were needlessly butchered. Here is the result.
