Scientists at Thomas Jefferson University have demonstrated that a normally protective anticancer gene can block tumors from growing. Led by Dr. Antonio Giordano, they found that the damaged version of the gene, pRb2/p130, suppresses tumor growth in animal models, paving the way for gene therapy to treat lung cancer and other cancers.
A new study suggests that depression is a fluid disease requiring tracking over time for accurate diagnosis and treatment. Researchers found that physicians more frequently detected depression when they knew their patients well, but struggled to distinguish it from minimal impairment.
The University of Colorado at Boulder's archaeological team, led by Professor Payson Sheets, is developing a five-year conservation plan for the ancient village of Ceren. The plan aims to preserve the site's structures, artifacts and agricultural features using ground-penetrating radar and climate-controlled environments.
A study of eight large clinical trials found that mammography screenings for women in their 40s add only about five days to life expectancy and may not significantly reduce breast cancer deaths. However, the overwhelming proportion of women experience no benefit from screening.
