U.S. underestimates
mine threat in Gulf

Student finds error

6.
'

WASHINGTON (AP) - The
Navy underestimated the threat posed
by Iranian mines when it prepared to
carry out President Reagan's plan to
protect Kuwaiti tankers, the nation's
top military officer said yesterday.
"I think it's eminently fair to say
we made a number of underesti-
mates," Adm. William Crowe Jr.,
chair of the Joint Chiefs of Staff,
told the Senate Armed Services
Committee.
"Obviously we didn't want the
Bridgeton to happen," he said, refer-
ring to the July 24 incident when the
first reflagged Kuwaiti tanker hit a
mine while it was being escorted by
U.S. Navy warships.
"We made some mistakes," he
said. "If I had it to do over again, I
wouldn't do it that way."
He said the Navy "probably over-
rated our intelligence" about Iranian
capabilities.

The Navy is now looking at ways
to reduce the number of ships and
men in the region, Crowe said, but
he warned that it would be a "terrible
error" for the Democratic-controlled
Congress to order a U.S. withdrawl.
Crowe said the Pentagon is
"groping as to what the long-term
level of forces should be there....
We are looking at ways to draw
down our forces to a more reasonable
level."
Crowe spoke as the Senate was
considering a Pentagon budget bill
that Democrats want to use as the
vehicle for a proposal that would
halt the reflagging program within
90 days unless both the House and
Senate approve it.
Earlier yesterday, the Senate voted
96-0 approval of an ammendment to
the bill praising the U.S. military
who took part in last week's attack
on an Iranian ship caught laying
mines.

in Newton
By DAHLIA DEAN
As an undergraduate at the Uni-
versity of Chicago, Robert Garisto
wrote a paper for his history of sci-
ence class that evolved into an im-
portant scientific discovery.
Garisto, currently a first year
graduate student in physics at the
University of Michigan, last Febru-
ary found the first error in calcula-
tions in Sir Isaac Newton's Princip-
ia.
Needless to say, he got an A-plus
for the paper.
Newton's 600-page Philosphiae
Naturalis Principia Mathematica
established, among other things, the
laws of motion and the theory of
gravity. In proposition eight of
Book Three, Newton tried to
demonstrate his theory by calculat-
ing the mass, surface gravity and
density of the known planets.
Garisto discovered that Newton
incorrectly copied his data from one
draft to the final draft, which resulted
in an error in his figure for the mass
of the earth.
"The value for the mass of the
earth in Newton's final edition actu-
ally corresponds to the value he cal-
culated in a previous edition,"
Garisto said. "He probably recalcu-
lated the figure for the mass of the
earth correctly, but never put the
correct results down in the final edi-

s theory
tion."
The error has gone undetected;
Garisto speculated, partly because
people working through the calcula-
tion would think they made the
mistake, not Newton.
He added, "It's not something,
readily apparent without an
evening's work, and the data and the
equations are not explicitly stated in
the proposition." ;
Ironically, the discovery came
exactly 300 years after the 1687
publication of Principia. After the
find, Garisto became the focus of
national attention when a dozen radi
and television shows and 1,200
newspapers - including the Miami
Herald and the New York Times -
publicized his find.
"The publicity and attention is
testament to how practically-error-
free the Principia is," Garisto said..
Garisto followed up the original;
paper with a more extensive paper:
on his discovery. He submitted that
to the scientific honor society, Sig-
ma Xi, where he won the University
of Chicago chapter's prize for excel-
lence in science.
Last June, Garisto received his
bachelor's degree in physics. He is
now working on his doctorate at the.
University, taking graduate classes'
and teaching labs.

Prof. rewarded for sparing animals in research

By MELISSA RAMSDELL
A technique that reduces the
number of animals used in hearing
loss experiments has earned a
University professor global atten-
tion.
Medical School Prof. Jochen
Schacht received the Animal Welfare
Award from the German-based Erna
Graff Foundation for the Protection
of Animals. The $5,000 grant will
go toward the continuation of
Schacht's "promising endeavors."
Schacht and Pharmacy Prof.
Norman Weiner previously used
guinea pigs and rodents to test how
certain widely used antibiotics cause

hearing loss. The animals were
injected with the drug over a period
of several weeks while the research-
ers monitored the animals to see
whether the drug affected their
hearing.
The new testing technique
bypasses live animal testing because
it examines the drug's interaction
with artificial cell structures, called
liposomes, obtained from c o w
brains. Weiner said the new
procedure, which uses cows
slaughtered for commercial purposes,
would save approximately 100 test
animals over a six month testing
period.

protest verdict in trial

(Continued from Page 1)
The group marched next to the
Phi Gamma Delta fraternity house-
where the incident allegedly oc-
curred- for a silent vigil. "Violence
happened there and we're not going
to forget it," Cohen told the group.
Catherine Fischer, a coordinator
of Washtenaw County's Women's
Crisis Center, said the "not guilty"
verdict angered and frightened her.

"It really shows people need to
wake up and see what happens when
attitudes about women and sexual
assault continue unquestioned," she
said.
Fischer said the defendant's
counter defamation suit is a harass-
ment tactic. "I hope it does not be-
come a trend. It's punishment for the
survivor to speak out and is designed
to keep women from saying what
happened."

The antibiotics cause hearing loss
by damaging the membranes of fine
hair cells in the ear; the cells convert
sounds into nerve impulses which
are then picked up by the brain.
Doctors first discovered that some
antibiotics caused hearing loss in the
1940s in patients being treated for
tuberculosis.
Schacht said that between two and
14 percent of the two million
patients treated with these drugs per
year experience some loss of
hearing.
The guinea pigs' hearing was
tested by measuring nervous system
activity to and from the anaesthetized
animal's inner ear. While the ani-
mals did not feel pain during the
procedure, many were left perma-
nently deaf.
Schacht's new technique is used
to discover how the antibiotic causes
deafness through its effect ,on the
liposome. When combined with the
antibiotics, liposomes react in a way

that is similar to that of a human
cell membrane.
If the liposome's membrane is
damaged by the drug, researchers
assume the drug will cause similar
damage in the human ear. This
confirms the drug's toxicity.
"This could be a substitute to
screen drugs for toxicity instead of
using animals.... I think every
animal you can save is a worthwhile
effort," Schacht said. Weiner added
that the model is also less time
consuming than the use of animals
for testing because researchers will
be able to determine the drug's
potential ability to cause hearing
loss within a week rather than over
several months.
Schacht could not: predict how
widely his screening technique wil
be adopted. But, he said, if
companies do use the technique, "it
will by the same token will reduce
animal research in companies."
