MIT develops 'tractor beam' for cells, more

In a feat that seems like something out of a microscopic version of Star Trek, MIT researchers have found a way to use a "tractor beam" of light to pick up, hold and move around individual cells and other objects on the surface of a microchip.

3. Extracellular protein sensitizes ovarian cancer cells to chemotherapy
   12-10-2007 · EurekAlert!
   Scientists have uncovered critical new details about the mechanisms that modulate the response of ovarian cancer cells to chemotherapy. The research, published by Cell Press in the December issue of Cancer Cell, helps to explain why many patients develop resistance to the taxane class of drugs and may lead to improved treatment of ovarian cancer.

4. Why your fertility cells must have 'radio silence'
   01-29-2008 · EurekAlert!
   Researchers in Kobe, Japan, and Montreal, Canada, have uncovered a previously unknown mechanism which causes embryonic germ cells -- which later develop into sperm or ova -- to go through a period of "transcriptional silence," during which information from the cell's DNA cannot be copied. Without this important phase, unique to cells of this type, an organism produces sterile offspring. Their results were published in January 2008, in the journal Nature.

5. Researchers develop marker that identifies energy-producing centers in nerve cells
   02-01-2007 · EurekAlert!
   A protein that causes coral to glow is helping researchers at the University of Maryland School of Medicine to light up brain cells that are critical for the proper functioning of the central nervous system. This fluorescent marker protein may shed light on brain cell defects believed to play a role in various neurological diseases.

6. Gene Key To Taste Bud Development Identified
   10-02-2006 · ScienceDaily
   Scientists have identified a gene that controls the development of taste buds. The gene, SOX2, stimulates stem cells on the surface of the embryonic tongue and in the back of the mouth to transform into taste buds, according to the researchers. Stem cells are immature cells that can develop into several different cell types depending on what biochemical instructions they receive.

7. Chemical cues turn embryonic stem cells into cerebellar neurons
   03-14-2007 · EurekAlert!
   Rockefeller University scientists show that embryonic stem cells implanted in the brain appear to develop into fully differentiated granule neurons, the most plentiful neuron in the cerebellum. The findings are a step toward understanding how embryonic stem cells could be regulated in vivo and ultimately used for cell replacement therapy, especially after childhood tumors, in the central nervous system.

8. Human stem cells delay start of Lou Gehrig's disease in rats
   10-15-2006 · EurekAlert!
   Researchers at Johns Hopkins have shown that transplanting human stem cells into spinal cords of rats bred to duplicate Lou Gehrig's disease delays the start of nerve cell damage typical of the disease and slightly prolongs life. The grafted stem cells develop into nerve cells that make substantial connections with existing nerves and do not themselves succumb to Lou Gehrig's, also known as amyotrophic lateral sclerosis (ALS). The study is published in this week's issue of Transplantation.

   On a microscopic level, coaxing cells to be very, very close without actually touching one another has been among the most frustrating challenges for cell biologists. MIT researchers have solved the problem with a novel device.

10. Carnegie Mellon scientists develop fluorescent proteins for live cell imaging, biosensor design
    02-06-2008 · EurekAlert!
    Scientists at Carnegie Mellon University's Molecular Biosensor and Imaging Center have developed new "fluorogen activating proteins" that will become a key component of novel molecular biosensor technology being created at Carnegie Mellon. The FAPs, which can be used to monitor biological activities of individual proteins and other biomolecules within living cells in real time, are described in the February issue of Nature Biotechnology.
