Totem in 3D: Museum of Anthropology Recreates
a Northwest Coast Monument
One pixel at a time, by erica smishek
Imagine being able to "travel through" a traditional Northwest Coast village site that no longer
exists.
Thanks to three-dimensional laser scanning
technology, the Museum of Anthropology (MOA)
at UBC may one day make this virtual re-creation
a reality.
"New tools are changing the way we're teaching and conducting research, the way we're preserving and presenting cultural objects," says
MOA projects manager/curator Bill McLennan.
"The future is almost scary."
In consultation with the Haida Nation,
McLennan and his colleague, designer Skooker
Broome, worked with a Vancouver-based firm to
scan a totem pole collected from the Ninstints
Village on the Queen Charlotte Islands in 1957
and now housed in the museum. The totem,
which dates back to the mid-19th century, features a bear with a frog in its mouth and a wolf.
It has weathered, been broken into three parts
and carries only small traces of its original paint.
"The technology allows us to basically retrieve
the information that is in a piece so the information isn't lost," says McLennan. "We can make it
available for people studying the culture, or for
young artists learning their craft."
The tripod-mounted portable scanning system
measured every square millimetre of the entire
surface geometry of the totem in "xyz" coordinates, thereby completing a digital record of
the monument and capturing it in the form of a
point cloud - a dense, accurate and interactive
3-D model that can be rotated and viewed from
any perspective on a computer.
"First we get an exact wire mesh of the whole
piece," McLennan explains. "Then we can lay on
the 'skins' [layers of wood]. Working with contemporary artists, we can determine what the
colours were like in the 1850s when it was
carved. We can also bisect the pole at any point
and can get an exact representation of the thickness of the wood."
A plastic model generated from a 3-D laser
printer as well as two-dimensional prints provide
additional documentation of the object.
Developed by Leica Geosystems, an international company serving customers in surveying, engineering, construction, GIS, mapping, industry and
other areas of activity, the 3-D laser scanner has
traditionally been used as a tool to create "as-
built" documentation of large structures and sites
like pulp mills, oil refineries and dams. Scanning
provides a safe, time-efficient, cost-efficient and
accurate way to determine how a building has
changed since it was built.
More recently, companies that market the product have looked for other applications to showcase the technology, using it to prepare "as-
found" documentation of dinosaur bones,
European cathedrals and castles, and even the
Statue of Liberty.
"Traditional technology has not been able to
capture that much data," says Christine Young,
who worked on the pilot project with MOA.
"With 3-D scanning, it's almost overkill what you
can do with it."
Young, director of marketing for a firm that
distributes the scanners, explains they can be
positioned at significant distances from the structures that are being measured, eliminating the
need for activities such as climbing and crawling
that pose the risk of accident or the need to physically touch items that are often very vulnerable.
Moreover, she says, people don't have to be in
the same room as the object in order to benefit
from the data, thereby expanding the research

Dried starfish
^fccandleholders. Toy
cars sporting sea urchin
wheels. Sand dollar necklace
pendants. Souvenirs crafted
from dead sea life have
become such a ubiquitous part
of the scenery in tropical

these curios were once living

In a new exhibit opening
this month, Chicago's Shedd
Aquarium hopes to raise public awareness of the issue
using research conducted by
Project Seahorse, an international marine conservation
and research organization
based at UBC.
Project Seahorse's contribution to the "Sea Star Quest"

urchins, sand dollars, and
heart urchins. More than
1,500 different species of
these live in tidal waters
worldwide but little is known
about the global trade in sea
stars or urchins for use as
souvenirs.
Drawing on her previous
experience as a trade surveyor in southeast Asia, Project
Seahorse researcher Kristin
Lunn traveled to Mexico in
February to interview fishers,
distributors and retailers in
several of Mexico's key resort
areas including Mazatlan,
Puerto Vallarta, Cancun and
Cozumel.
"We had this idea that sea
stars were being taken for the
curiosity trade but we didn't
have any idea how many
were being traded and what
that would mean for wild
populations," Lunn says.

Highlights of UBC Media Coverage in May 2004. compiled by brian lin
Troy Good for the Classics
Commenting on the recent blockbuster epic film Troy, starring
Brad Pitt as Achilles, Shirley
Sullivan, head of the classics
department at UBC, said most of
her colleagues are willing to overlook the film's faults for the interest it will spark in the ancient
world.
"Anything that broadens the
person's perspective, that takes
them into the past and makes
them see a wider range of history,
can't but do good. Even if it's a
distortion," Sullivan told
Canadian Press.
Sullivan said other epic movies
have boosted the study of the
antiquities, including Gladiator,
starring Russell Crowe and movie
classic Ben Hur.
Jelly Fish for Lunch?
Kicking off the World Fisheries
Congress in front of 1,500 fisheries scientists from around the
globe, UBC fisheries professor
Daniel Pauly, one of the world's
leading fisheries researchers,
showed how people's growing
appetite for seafood has driven
fishing boats from industrialized
countries ever farther into
Southern Hemisphere seas controlled by Third World nations.
In the wake of the disastrous
crash of the North Atlantic's cod
stocks, the Newfoundland government is encouraging fishermen to
go after jellyfish, said Pauly, who
in November was chosen by
Scientific American as one of the
top 50 fisheries scientists in the
world, reports The Seattle Post
Intelligencer.

Bell Gives UBC $1.25 Million
for Tech Research
Bell Canada recently announced a
$1.25-million commitment to UBC
to support technology research.
The five-year commitment is the
first in Western Canada for the Bell
University Laboratories program,
reports The Globe and Mail.
Bell is exploring a number of
potential projects with UBC
researchers. Projects will focus on
wireless technology and social
computing.
The Truth About Echinacea
Commenting on a new U.S. study
that says echinacea doesn't help
prevent colds, UBC alternative
therapy researcher Lloyd Oppel
told Global National that "echi
nacea is not delivering on the
promise that it's held out to have.
So this study is very much in
keeping with that."
Placebo Effect Revealed
Experiments conducted by Italy's
University of Turin Medical
School have revealed the action of
the placebo effect in Parkinson's
disease patients.
"The research provides further
evidence for a physiological
underpinning for the placebo
effect," UBC neurologist
Jon Stoessl told New Scientist.
His team demonstrated in 2001
that placebos can relieve
symptoms by raising brain levels
of dopamine, a beneficial
neurotransmitter. □
Dynamic Teaching Earns Faculty Killam Awards
There are three rules in Dr. Bob's classroom, says one
student of music professor Robert Pritchard. 1) Don't
Panic; 2) Stay with the tour; and 3) If you don't

approach earned him one of 22 Killam Teaching
Prizes, awarded to faculty members during Spring
Congregation ceremonies.
Other winners include Education Prof. Pat
Mrenda, North America's leading authority on
autism, and Botany Prof. Jennifer Klenz, an expert on
plant and drosophila (fruit fly) genetics.

UBC Researcher Seeking a Cure for Baldness
Solution could be available within ten years, by Hilary Thomson
Researcher Kevin McEiwee -
one of only a few people in the
world who hold a doctoral
degree in hair biology - thinks a
cure for baldness that uses the
technique of hair cloning could
be commercially available within
10 years.
Hair cloning is a slang term for
engineered hair growth. The
process involves isolating a group
of cells at the base of the hair follicle - the living part of hair rooted in the skin. Once the follicular
cells are multiplied in a laboratory, they can then be implanted
back into the donor's scalp where
they divide to create new follicles
and generate new hair.
A sample of about 10 hairs
could produce several million cultured cells, which, in turn, could
grow several thousand hairs. (See
sidebar for information on scalp
hair population.)
Scientists have been studying
hair cloning in animal models for
a few years, but McElwee is the
first investigator to demonstrate
exactly how cloning works.
"Now that we have proof of
how this process works, we can
accelerate the research toward
creating a limitless supply of hair
- in effect, a cure for baldness,"
says the 34-year-old.
While early results are promising, he estimates it will take
almost a decade of further study,
clinical trials and meeting regulatory requirements before cloning
is widely available.
Common or pattern balding
affects about 20 per cent of men
in their 20s. By age 50, about half
the male population and 20 per
cent of women have problems
with baldness or hair thinning.
An expert in the cellular
mechanics of hair loss and
growth, McElwee was recruited
by Dr. Jerry Shapiro, a world
authority on hair disorders, to
join the division of dermatology
in UBC's department of medicine
in March 2004. Also an investigator with the Vancouver Coastal
Health Research Institute,
McElwee came to Canada from
Philipp University in Germany
where he was a senior scientist in
the department of dermatology.
A biologist and immunologist,
McElwee completed his unique
PhD in the immunological mechanisms involved in alopecia areata, an inflammatory hair loss disease that can affect men, women
and children and cause full body
hair loss. The cause of the disease
is not fully understood but it is
believed that an individual's own
immune system prevents hair follicles from producing hair fibre.
This month, McElwee will
travel to the International
Meeting of Hair Research
Societies in Berlin to present his
findings on the cells believed to be
the primary culprits in causing the
disease.
By separating cells in lymph
nodes, McElwee has determined
which cells are capable of inducing
the disease. He found two types of
cells caused balding problems:
CD8, which produce patchy
baldness and CD4, which produce
systemic balding.
"This research is the first

evidence that CD4 cells are our
primary target in fighting
alopecia areata," he says. "This
new data will help us develop
interventions and treatments to
ease or stop this condition which
can be psychologically devastating for patients."
Shapiro and McElwee will
host the International Meeting
of Hair Research Societies in
Vancouver in 2007.

Did you know?
• On average, each person has a total of 20 million hair follicles on
their skin, of which 90,000 to 140,000 are scalp hair follicles.
• You can lose up to 25 per cent of your scalp hair before it becomes
noticeable.
• Typically, scalp hair fibres grow for two to seven years before being
replaced by a new hair fibre.
• People may lose up to 100 scalp hairs a day as a result of normal
hair cycling.
• The numbers of hairs on the head vary with colour. Redheads have
about 90,000 hairs and black-haired people about 108,000 hairs,
while brown- and blonde- haired people have up to 140,000.
• On average, hair is composed of about 50 per cent carbon, 21 per
cent oxygen, 17 per cent nitrogen, as well as hydrogen and sulphur.
Hair also contains trace amounts of magnesium, arsenic, iron,
chromium and other metals and minerals.
• Circus performers who hang by their hair know how strong it is. In
theory, you could gradually hang between 5,600kg and 8,400kg
from one head of hair without breaking individual hairs.
• The North American hair loss industry is estimated at $7 billion a
year. □
