"Streptamer" Technology, Novel Approach to Cell Sorting, Characterizing |
|
Thursday, 21 January 2010 |
Lifescienceleader.com has reported Beckman Coulter, Inc.'s new addition of Streptamer Technology, a method of isolating and characterizing functional anitgen-specific T-cells by fluorescence-activated or magnet-assisted cell sorting manufactured by IBA GmbH, to their currrent product lines. This process is reversible which
leaves the isolated T-cells phenotypically and functionally
indistinguishable from untreated cells. This technology has the
potential to advance basic T-cell research as an essential prerequisite
for revolutionary immunological medicines.

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.
