designing wearable devices
To analyze how and why older people fall, U.Va. researchers want
as much information as possible about how they walk. But studying
someone in a lab filled with video cameras and motion sensors
is hardly a natural setting. So Jim Aylor, left, and John Lach
are looking for ways to take the lab to the study subjects, designing
portable, wearable devices to collect data as people go about
their normal lives.

the elderly fall.
Married couples’ real income dropped in 2001
After six consecutive years of gains, median adjusted gross income
for married couples took a dip in 2001. A new report by U.Va.’s
Weldon Cooper Center for Public Service shows that a 1.9 percent
income growth rate could not keep pace with a 2.8 percent annual
inflation rate, causing a loss. “The main reason for the
drop was the reversal of fortune for persons who had previously
benefited from the stock market boom,” said John L. Knapp,
the center’s director of business and economics research.
Scientists make model of Parkinson’s disease
As many as 1 million Americans suffer from Parkinson’s disease.
Scientists at U.Va.’s Health System for the first time have
engineered cells that replicate features of the disease, including
Lewy bodies — tiny balls of damaged protein — found
in the brain cells of all patients with Parkinson’s. Scientists
plan to use the cellular model to study the development and function
of Lewy bodies.
