Despite clinical and experimental evidence implicating the intestinal microbiota in a number of brain disorders, its impact on Alzheimer's disease is not known.

A new study from the Monell Center, the U.S. Department of Agriculture (USDA), and collaborating institutions reports a uniquely identifiable odor signature from mouse models of Alzheimer's disease. The odor signature appears in urine before significant development of Alzheimer-related brain pathology, suggesting that it may be possible to develop a non-invasive tool for early diagnosis of Alzheimer's disease.

In the February 19, 2014 issue of Science Translational Medicine (Sci Transl Med. 2014 Feb 19;6(224):224ra24), Bettegowda and colleagues in the Sol Goldman Pancreatic Cancer Research center at Johns Hopkins report on an exciting approach to the detection of pancreatic cancer. Bettegowda and colleagues applied cutting edge DNA sequencing to blood samples from a large number of patients with a number of different cancers. They found that many cancers, even some small curable cancers, shed mutant DNA into the blood.
