Cancer Research: Why elephants rarely get cancer ♦ Scientists pave way for diamonds to trace early cancers ♦ Researchers create 'leukemia in a dish' to better study it

Why elephants rarely get cancer A new study could explain why elephants rarely get cancer. The results show that elephants have extra copies of a gene encoding a tumor suppressor, p53. Further, elephants may have a more robust mechanism for killing damaged cells at risk for becoming cancerous. The findings suggest extra p53 could explain elephants' enhanced cancer resistance.
Scientists pave way for diamonds to trace early cancers Physicists have devised a way to use diamonds to identify cancerous tumors before they become life threatening. Their findings reveal how a nanoscale, synthetic version of the precious gem can light up early-stage cancers in non-toxic, non-invasive Magnetic Resonance Imaging scans.
Examining contemporary occupational carcinogen exposure, bladder cancer Despite manufacturing and legislative changes to improve workplace hygiene, the risk of occupational bladder cancer appears to be on the rise in some industries, although the profile of at-risk occupations has changed over time.
Scientists engineered stem cells to better understand the mechanisms behind a form of leukemia caused by changes in a key gene.
