Study shows what leads to a science career
EAST LANSING, Mich. - Michigan State University researchers
say they've found parental influence and access to math
courses are likely to guide students into science careers.
Professor Jon Miller, who led the study, said the education
of more people in the fields of science, technology,
engineering mathematics and medicine is crucial for the
nation. "Failure to build and maintain a competitive
scientific workforce in the decades ahead," Miller said,
"will inevitably lead to a decline in the American standard
of living." Miller used data from the Longitudinal Study of
American Youth, which kept track of nearly 6,000 students
from middle school through college, attempting to determine
what led them to or away from science-based careers. Miller
said the research showed the path to a science career begins
at home, and that is especially true in families in which
children were strongly encouraged to go to college. "Only
four percent of students who experienced low parent encour-
agement to attend college planned to enter a post-secondary
program and major in a (science) field," he said. "This
compares to 41 percent of students whose parents strongly
encouraged college attendance." The research also reinforced
the role mathematics plays. "Mathematics is a primary gate-
way to a (science) career, beginning with algebra track
placement in grades seven and eight, and continuing through
high school and college calculus courses," he said. The
study's findings were presented recently in San Diego during
a meeting of the American Association for the Advancement of
Science.

More images of Enceladus are released
PASADENA, Calif. - NASA says it has released new images of
Saturn's icy moon Enceladus that were taken by the Cassini
spacecraft in November. Space agency scientists said those
images reveal a forest of new jets spraying from prominent
fractures crossing Enceladus' south polar region, yielding
the most detailed temperature map to date of one fracture.
NASA said the images from the imaging science subsystem and
the composite infrared spectrometer teams also include the
best 3D image ever obtained of a "tiger stripe" -- a fissure
that sprays icy particles, water vapor and organic compounds.
There are also views of regions not well-mapped previously
on Enceladus, including a southern area with crudely circular
tectonic patterns. "Enceladus continues to astound," said
Bob Pappalardo, Cassini project scientist at NASA's Jet
Propulsion Laboratory in Pasadena, Calif. "With each Cassini
flyby, we learn more about its extreme activity and what
makes this strange moon tick." For Cassini's visible-light
cameras, the Nov. 21 flyby about 1,000 miles from the moon's
surface provided the last look at Enceladus' south polar
surface before that region of the moon enters 15 years of
darkness. The images and additional information are available
at http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov.
Math models used to study cell processes
BLACKSBURG, Va. - A Virginia Tech professor of biology says
he is using math-based computer models to discover how cells
process information and make decisions. Professor John Tyson
says he and other biologists want to know how jumbles of
molecules can figure out how a cell should respond to its
environment to survive, grow and reproduce. "So we do what
any good engineer would do," he said. "We create a mathe-
matical model of the components and their interactions, and
let the computer work out the details. Tyson said scientists
still do not have an engineer's understanding of normal
mammalian cell proliferation and of what goes wrong in cancer
cells. "Cancer treatment is still a matter of cutting out,
blasting, or poisoning cancer cells -- and any normal cells
that get in the way," he said. "We could be more subtle and
perhaps more effective in treating cancers if we had a sys-
tematic insider's understanding of the molecular networks
that control cell growth, division and death, and an ability
to manipulate this control system with a new array of drugs
and procedures." Tyson presented his research Sunday in San
Diego during a meeting of the American Association for the
Advancement of Science.

Tired of throwing out rotten food? Brawny Produce Protector
Bags prolong the life of your fruits, vegetables and cut flowers
without the use of chemicals. Stock up on produce without
worrying about rapid spoilage or extend the life of your home-
grown fruits & veggies.
HOW PRODUCE PROTECTOR BAGS WORK:
Fruits, vegetables and flowers release ethylene gas while
ripening after harvesting or picking. Ethylene gas accelerates
ripening, aging and rotting. Forever Bags absorb and remove this
damaging gas, dramatically extending the life of fruits,
vegetables and flowers.

Discovery to move to its launch pad
CAPE CANAVERAL, Fla. - Space shuttle Discovery is being
readied for its move to Launch Pad 39A at Florida's Kennedy
Space Center for a flight to the International Space Station.
Discovery's approximately six-hour, 3.4-mile journey atop a
giant crawler-transporter is to start next Tuesday at
12:01 a.m. EST. NASA TV will provide live coverage of the
event beginning at 6:30 a.m. Next Tuesday will also mark the
day Discovery's astronauts and ground crews will participate
in a launch dress rehearsal, known as the Terminal Countdown
Demonstration Test, NASA said. The test provides each shuttle
crew with an opportunity to participate in various simulated
countdown activities, including equipment familiarization
and emergency training. The crew's arrival at the space
center is set for 7 p.m. Monday, with the event carried live
on NASA TV, as well as a crew news conference March 4 at
8:40 a.m. EST. Discovery's STS-131 crew will be commanded
by Alan Poindexter, with James Dutton Jr. serving as the
shuttle's pilot. The other crew members are astronauts Rick
Mastracchio, Dorothy Metcalf-Lindenburger, Stephanie Wilson,
Clayton Anderson and Japan Aerospace Exploration Agency
astronaut Naoko Yamazaki. The shuttle will deliver science
racks to be used in space station laboratories. Launch is
set for 6:27 a.m. April 5. NASA TV downlink information,
schedules and links to streaming video are available at
