High Through-Put for a Faster Sequence |
|
Wednesday, 13 January 2010 |
|
Today Genomeweb.com announced Illumina's unveiling of a new genome sequencer which will allow researchers to sequence up to 11,000 human genomes per year. This sequencer has a second flow cell that allows a much higher through-put of information, but increases the cost for reagents. The hope is that this sequencer helps to bolster the sagging genome studies field.

Shining a Light on Brain Behaviors |
|
Monday, 11 January 2010 |
As reported on January 6 on Forbes.com, Ed Boyden, a Neuroscientist at Massachusetts Institute of Technology, has discovered a way to use light to shut off portions of the brain in order to study behaviors associated with specific areas. The brain is reactivated once the light is turned off. Dr. Boyden has discovered a gene, that when introduced to the brain, instructs cells to pump protons when hit with a certain color of light, thereby changing the electrical charge of the cell and preventing it from sending signals. Dr. Boyden has yet to try it in humans due to the unknown adverse reactions of introducing this gene into the brain.

Capitalizing on Viral Mutations |
|
Tuesday, 05 January 2010 |
|
As reported today in the New York Times, scientists at several universities are continuing a study initially discovered at the University of Washington; by manipulating a viruses predilection for mutation, they can use it to eradicate the virus. As science has seen many times before, a virus has the ability to mutate, thus becoming a completely new strain that is resistant to antiviral drugs. Science have found that by increasing the virus' mutation rate, the virus can no longer produce viable offspring, hopefully ending that strain. There is, however, some concern over this technique. Scientists are afraid that even this is not an insurmountable roadblock for some viruses and they may become resistant even to this process.

New, Smaller Cytometer Has High Throughput Capabilities |
|
Monday, 28 December 2009 |
|
According to RSC.org, scientists at University of California, Los Angeles have created a flow cytometer that is capable of analyzing up to one million blood cells per second. Normally flow cytometers are only capable of analyzing cells through one channel; this new cytometer has 256 channels for cells to flow through. This device is also smaller and uses less sheath fluid than normal cytometers, thus increasing accessibility to this technique in both cost and space requirements.
