Birds, Bees
Still Have
One Secret
Bj ASSOCIATED PRESS
Bird and bee navigation se
crets, balloons for scientists,
and a space jaywalker are top
ics in science news:
BIRD AND BEE SECRETS
Humans have made great
progress in developing guid
ance systems for space ve
hicles, but "it will take 100
years for electronics to catch
up with the sophisticated guid
ance and sensory systems of
the birds and the bees," says
John L. Burns, former president
of Radio Corporation of Ameri
ca. "Evidence now at hand sug
gests that in flight the bat
finds his way by bouncing ultra
sonic waves off solid objects;
the pigeon homes on the mag
netic lines of the earth; a bird
flies thousands of miles from
the tree branch in your back
yard, and returns to the same
branch, through stellar naviga
tion. "The eye and brain of the
hungry frog filters out all dis
cordant information except the
movement of the fly his palate
craves a superb example of
image recognition and interpre
tation. "If we could only translate
this characteristic into a mathe
matical formula and then into
hardware we could endow an
V.nrHi Satellite un4h a oimH.,.
ly adaptable 'eye' that would se-!
led the precise information it
was sent aloft to obtain."
FLOATING LABORATORY
Scientists are getting their
own special balloon flight sta
tion, to be set up this summer
at Palestine, Tex.
From this base, they can re
lease balloons lofting up instru
ments for high altitude study of
the atmosphere and weather
phenomena. For astronomical
studies above the clouding ef
fects of the Earth's air, and for
capturing primary cosmic rays.
Long planned, the balloon fa
cility will be built and operated
by the National Center for
Atmospheric Research at Boul
der, Colo., with the tab paid by
the National Science Founda
tion. It is part of the center's
scientific balloon program, de
signed to spur improvement in
balloon technology for scientific
rwwaroh.
SPACE JAYWALKER
Hermes it the name of one
of the Sun's minor planets, a
chunk of rock about a mile in
diameter, weighing perhaps
three billion tons.
Unlike other minor planets
which follow orderly paths be
tween Mars and Jupiter, Her
mes has an eccentric orbit, and
can actually come within about
200,000 miles of the earth,
closer than the Moon itself,
and a near miss, cosmically
speaking.
But the chance that it or
similar bodies would ever col
lide with the Earth with de
vastating effects is infinitesmal
ly small, says John MacVey in
Space Digest Magazine.
Perhaps, he suggests, men in
space ships one day might be
able to rendezvous with one of
the minor planets possessing a
wide-ranging orbit, equip it with
transmitters, and let it send
back data on the reaches of
space it visits.
PURITY
In some electronic devices,
99.9999 per cent pure isn't good
enough, particularly in highly
pure semi-conductor crystals of
materials such at silicon and
germanium.
To find such flaws, a newly
installed Instrument at Sperry
Rand Research Center, Sudbury,
Mass., can detect one atom of
"impurity" in a billion atoms.
It was made in England, and
there is only one other instru
ment like it in the United
States. It is a double-focus,
spark-source mass spectrograph,
which detects differences in
weights of atoms within a given
material.
Royal Flight
LONDON Wl The Princess
Royal, aunt of Queen Elizabeth
II, will be the first member of
Britain's royal family to fly the
polar route to North America
when she leaves London this
week for a two-week Canadian
visit. She will make the flight
In a Royal Canadian Air Force
Yukon plane.
