Growing Concern Over CT Radiation Exposure |
|
Tuesday, 22 December 2009 |
|
While computed tomography (CT) scans have helped to save thousands of lives by providing accurate diagnoses, scientists at the University of California, San Francisco (UCSF) have discovered that the amount of radiation the body receives at current levels
of CT usage is enough to result in 29,000 new
cancer cases and 15,000 new cancer deaths each year (based on current cancer cure rates). They also found that the amount of radiation was wildly variable and at a much higher level than they had expected. New radiation protocols are being put into play at UCSF in order to mitigate the risk of too much exposure.

Cells Move In Mysterious Ways |
|
Thursday, 17 December 2009 |

Brown University reports that their scientists, in collaboration with California Institute of Technology, have made a new discovery in the movement of cells. They've learned that cells move in three dimensions by measuring the force exerted by them on their surroundings in a "push-pull" fashion. The scientists' experiments revealed that cells move by redistributing weight, coiling or elongating their body, and varying force with which it adheres to a surface. This discovery may help scientist understand how the movement of a cell changes when it becomes diseased.
