Blood Test Could Diagnose Early-onset Alzheimer’s

October 29, 2014 10:58 am | News | Comments

A non-invasive blood test that could diagnose early-onset Alzheimer’s disease (AD) with increased accuracy has been developed by researchers. The new early-detection blood test could predict these changes and a person’s risk of developing AD much earlier than is currently possible.

Google Developing Pill to Detect Cancer

October 29, 2014 10:45 am | by Brandon Bailey - AP Technology Writer - Associated Press | News | Comments

Google is working on a cancer-detecting pill in its latest effort to push the boundaries of technology. Still in the experimental stage, the pill is packed with tiny magnetic particles, which can travel through a patient's bloodstream, search for malignant cells and report their findings to a sensor on a wearable device.

DNA-repairing Enzyme Can Worsen Tissue Damage

October 28, 2014 3:04 pm | News | Comments

When tissues are deprived of blood, as happens during a stroke or heart attack, the lack of oxygen can cause serious damage. A new study shows that surprisingly, a DNA-repair enzyme called Aag actually makes this damage worse.
