Under the leadership of Bob Franza, Cell Systems Initiative has
taken the first steps in enabling biology to make the conceptual
leap from describing the cell to understanding how a living system
works. Franza believes that to do this, scientists will need three
things: a specialized language for biological systems, a new array
of tools, and the means for extensive collaboration. Future biologists
will need to enter the field with experience in these areas, and
so CSI has embarked upon an educational initiative that will create
a virtual space to bridge the gap between the activities of the
research laboratory and the science classroom.
"Understanding cell systems will require the efforts of several
generations of biologists. We need to use animations and other techniques
to intrigue students and promote the study of biology," Franza explains.
The first step toward the creation of a virtual classroom is the
Labscape digital laboratory assistant, a model-based structure that
provides scientists (and students) a clear overview of the scientific/experimental
process.
Computer Scientist Larry Arnstein, the PI on the project, first
began thinking about computer uses in biology in 1999, although
the Labscape design and development process did not begin until
earlier this year. The development team includes Chia-Yang Hung,
Jing Su, Jong-Hee Kang, Gary Look, Stefan Sigurdsson, and Gaetano
Borriello.
"The major challenge was to cast the project in the right light,"
Arnstein says. "In looking for a way for biologists to communicate
better we realized that we had to come up with a language and tools
to make their lives easier. We needed to produce something immediately
sharable and understandable by others without any extra effort on
the part of the scientist. That something turned out to be the ubiquitous
lab assistant that we call Labscape."
Larry designed the Labscape user interface (a flow graph) so that
it can be used in a number of ways. Using live or recorded video
feed from a working biology laboratory, the Labscape assistant will
allow students to participate in experiments by following a protocol
in progress in the lab and watching the scientists perform the steps.
Students would link to the protocol interface used by the scientist
to see the recording and analysis of the real data generated by
the experiment. Mentoring relationships between students and scientists
would allow for a dialog to develop around the steps of the protocol.
A long-term goal for Labscape is to provide an easy way to design
experiments to test their hypotheses by selecting from preprogrammed
steps and protocols. Students or teams of students could design
and submit experiments to be carried out in the biology laboratory,
and could watch video of their experiments being performed, and
receive and analyze the results.
Students could also use Labscape to learn a protocol before actually
performing it in the school laboratory. Or the user interface can
provide an interactive experiment simulation tutorial, where the
students assemble the reagents and samples and perform the experiment
online.
CSI's Lisa Jenschke feels that one of the main strengths of the
Labscape assistant is that it will provide both an overview of the
procedure and accurate capture of details and results without the
need to record details in the traditional lab notebook and then
transfer them to the computer.
Labscape's transfer of large data sets, and use of live video feed
and extensive simulations make high bandwidth essential.
Over the next few months, the CSI development team and Joe Duncan,
Lisa Jenschke, Neil Fanger, and Paul Loriaux will be working with
selected high-school students on the further development of Labscape.
Joe Duncan explains why it is so important to include high-school
students in the development process. "Our hope and expectation is
that the next generation of biologists, which is in high school
now, will really embrace this type of tool. By the time these students
enter university, using tools like Labscape will be second nature
to them."
By Fall 2002, Labscape will be operational in an area high school,
with plans to expand the program to at least one other high school
the following year.
