Same-Sex Mating Discovered in a Toxic Fungus

...periments, the researchers found that, rather than being an asexual process, the hallmarks of mating occur during fruiting of alpha isolates. Unisexual fruiting involves the fusion of cells followed by meiosis, enabling genetic exchange between members of the same sex, they reported. Meiosis is the proces...

Technique may allow cancer patients to freeze eggs, preserving fertility before starting treatment

...e crystals cause damage that prevents the egg from being fertilized. U-M researchers looked beyond traditional techniques to a method of freezing cells called vitrification. This cryopreservation technique allows the eggs to be cooled fast enough that the transformation from liquid to solid is instantaneo...

Test for early detection of prostate cancer shows promise

...d prostate tumors,?said Getzenberg, In addition to being highly sensitive to prostate cancer, the EPCA test is also very specific to it, meaning that other cancers and benign prostate conditions are not detected, thus boosting doctors?confidence that a positive EPCA test is really a sign of prostate cancer...

Medical whistleblowers speak out

Study: 'homemade' gene expression technology unreliable

...tists can quickly pinpoint genes affected by drugs being tested to treat heart disease, mental illness, infectious diseases and cancer. In the past, researchers were only able to analyze a few genes at once, and they were often uncertain whether these were of greatest importance. Spencer's group is using ...
