Cervical cancer patients with specific changes in the cancer genome have a three- or fourfold increased risk of relapse after standard treatment compared to patients without these changes, according to a study by Norwegian researchers published November 13 in the open-access journal PLoS Genetics. The research suggests that specific genetic changes are crucial steps in [...]

Researchers in Egypt have developed a technique to compress DNA sequences of the kind used in medical research so that they take up a lot less space in a computer database but without loss of information. The approach is described in detail in a forthcoming issue of the International Journal of Bioinformatics Research and Applications.
Molecular [...]

Novel nanomaterials developed at Rensselaer Polytechnic Institute are scheduled to blast off into orbit on November 16 aboard Space Shuttle Atlantis.
The project, funded by the U.S. Air Force Multi University Research Initiative (MURI), seeks to test the performance of the new nanocomposites in orbit. Space Shuttle Atlantis will carry the samples to the International Space [...]

A compound in coffee has been found to be estrogenic in studies by Texas AgriLife Research scientists. Though the studies have not been conducted to determine recommended consumption amounts, scientists say the compound, called trigonelline or "trig," may be a factor in estrogen-dependent breast cancer but beneficial against colon cancer development.

New Mayo Clinic research studied the association between prostate-specific antigen (PSA) levels and prostate size and found that routine annual evaluation of prostate growth is not necessarily a predictor for the development of prostate cancer. However the study suggests that if a man`s PSA level is rising quickly, a prostate biopsy is reasonable to determine [...]
