Joe Simitian has spent nearly half his life in elective office, having served on the Palo Alto school board, the City Council, as mayor, on the County Board of Supervisors and in the State Assembly. Now he is in his second and final term in the State Senate. He is married to his political consultant. On paper, Mr. Simitian seems like the very definition of a career politician.

The article informs that a team of scientists of the Stanford University, Palo Alto, California, have developed a test that distinguishes the blood of people with Alzeimer's with those without the disease. Senior author of the new paper on the diagnostic test Tony Wyss-Coray states that they focused on enzymes involved in communication between the brain and body's immune system. The results indicate 80% accuracy in predicting the disease, but experts emphasize the need for larger studies.
