Cells able to switch genetic profile: Implications for cancer drug testing (October 16, 2010) -- Scientists have made a breakthrough in the way anti-cancer drugs are tested. A tumor cannot grow to a large size or spread until it has developed its own blood supply and leading research has looked for a way of halting capillary formation to stop tumors taking hold. But new findings have shown that scientists testing such treatments may not have been studying exactly what they thought they were. The research shows that cells are able to switch their genetic profile -- turning off genes expressed by blood vessel cells and turning on genes specific to lymphatic cells. ... > full story

Unsung hero: Researchers produce high-res model of Ndc80 in action (October 16, 2010) -- Scientists have used cryo-electron microscopy and three-dimensional image reconstruction to create a subnanometer resolution image of Ndc80, a protein complex that helps prevent chromosomal distribution mistakes during mitosis that can lead to birth defects, cancer and other disorders. ... > full story
Improving sonography: Spatial ability is key to becoming a successful sonographer, study finds (October 16, 2010) -- Diagnostic ultrasounds are the most widely used medical tests in the world. Though the technology is more than 50 years old, scientists continue to discover new uses for it, ranging from more targeted cancer treatments to liposuction. As the technology becomes more complex, a sonographer's skill level is even more important. Now, researchers may have found one of the keys to becoming a successful sonographer: spatial ability. ... > full story
