Sleep-wake cycle
fixed genetically,
crab study shows
WOODS HOLE. Mast (AP) —
The sleep-wake cycles found in both
humans and animals are apparently
fixed genetically at 24 hours — not
set bv the rhvthm of sunrise and
sunset after birth, according to a
new studv with horseshoe crab*.
Scientists found that the tiny crabs
must experience both light and
darkness to develop these «>-called
circadian rhythms. But once they
did. the cycle was approximately 24
hours king no matter what the
length of the "dav” and ''night'' to
which the crabs were exposed in the
laboratory.
Robert Barkm of Syracuse Uni
versity and the Marine BiologKal
laboratory in Woods Hole said
Tuesdas that his experiment is the
first one to show that individual ani
mals raised from birth in varying pe
riods of light and darkness would all
devekip circadian rhythms fixed at
about *24 hours in length.
drab* raised ironi birth in con
stant light or constant darkness had
no circadian rhythms, the scientists
found.
’■'I he one thing we can attribute to
the environment is the ttiEger,’* he
said. Cette in the brain, however,
have already set the length of the re
sulting rhythms at approximately 24
hours, he said.
Barkiw. who described his find
ings at the Marine Biok>gi<al Labo-
ntory’s (ieneral Scientific Meetings,
believes the same thing is true in
higher animals, including humans.
“I would be astounded if you raised
any animal in consunt conditions
and found a circadian rhythm,” he
said.
Studv of the origin and nature of
circadian rhvthms is important. Bar-
k»w said, because almost all bodily
processes that can be measured —
body temperature, bkiud sugar lev
els and even such things as pressure
within the eye — vary regularly over
a 24-hour period
“To find a puefess that does not
have a 24-hour modulation would be
a surprise." he said, let lag — in
which the body is unable to quickly
adjust to changes in sleep-wake cy
cles — is one obvious sign of the reg
ularity of these 24-hour cycles. Bar-
ktw said
For their research. Barkm and his
colleagues had to raise young horse
shoe crabs from birth in chambers
where light and darkness were con
trolled.
They collected horseshoe crab
eggs from nests on Cape Cod
beaches last year, fertilt/ed the eggs
in the laboratory, and alkmed the
crabs to be born in light-tight cham
bers.
The vrar-old crabs are now only
about a quarter o! an inch across,
but Barlow, using sophisticated elec
tronic equipment, can measure
changes in sensitivity to determine
how they experience circadian
i hvthms.
‘Firecam’
Aerial infrared camera aids
in fighting wildfires in Alaska
ANCHORAGE. Alaska (AP) — A
customized aerial camera th* uses
infrared film to see through smoke
is being used bv Alaska firefighters
to determine when — or if — wild-
tires should be brought under con
trol.
Alaska is so vast and so sparsely
settled that roughls 50 percent of its
270 million fire-prone acres are in
the unprotected, or “let burn" cat
egory. according to Elmer Hurd, as
sistant state forester for fire manage
ment .
“We can't afford to fight all the
fires." Hurd said. “And some fires
are good. So we've come up with a
formula for tire pi meet ion catego
ries.”
That formula is based on the
threat the fires pose to people or
property. The more dangerous the
lire, the quicker and more massive
the response.
If a fire were burning, for exam-
file. in an uninhabited area of bot
tomland spruce, officials mif^ht sim
ply watch the blaze and let it burn.
1 hat’s especially the case if it were
charring a fragile area, like tundra,
where building a road might perma
nently mar the permafrost.
But it the fire were advancing on
a village or threatening a histone site
or critical area where wildlife collect,
then the interagency federal-state
group would mobilize
Enter TROLL, or the state’s
I hernial Recorded Observation and
Loran I.m atmg System.
It’s a newly designed infrared
c amera and mapping system that lets
foresters peek through heavy smoke
to pinpoint hot spots and chart fire
perimeters.
An infrared camera mounted in
the bellv of a Korean War vintage
airplane is connec ted to a computer,
I \ monitor and video recorder in
the cockpit. The video package also
is linked to navigational aids on the
ground that pk>t the fire’s position
on a map.
Ron Hanks, the forestry division’s
c hiel pilot, said. “We can achieve ac
curacy within 50 feet.”
Hanks, ai 34, is only three years
older than the sturdy but nimble T-
28 he flies oul of Anchorage’s Mer
rill Field
The stale is making the system
available to other government agen
cies as a fire management tool, he
said.
