Yeast model system may provide a means for treating the earliest stage of Alzheimer's

A century ago this month, German psychiatrist Alois Alzheimer formally described characteristics of the neurodegenerative disease which ultimately came to bear his name. While international efforts to learn about Alzheimer's disease and develop treatments have progressed significantly in recent years, a cure remains an elusive goal.

Carbon nanotube amplification strategies for highly sensitive immunodetection of cancer biomarkers

In an attempt to increase the sensitivity of cancer biomarker detection and to decrease the need for large samples from which to detect those molecules, a multi-institutional research team has shown that a "forest" of single-walled carbon nanotubes can be used to detect lower levels of the prostate specific antigen (PSA) than is possible using the current commercial assay.
