Deserts into Farms ...
The use of atomic energy as a
peacetime explosive-offers interesting
prospects, according to the British
Council in London. Atomic explosives
may be used for remaking the land-
scape of the earth. They may be used
for blasting great holes in the earth
which can subsequently be changed
into lakes and canals. In this way
it might be possible, the Council
thinks, to produce lakes in the midst
of deserts and thus convert some of
the worst places in the world into
oases and fertile country lands.
DDT vs. Black Widow...
With the wind in the right direc-
tion and other conditions favor-
able, homes in certain sections of
the country- are subjected to a
shower of black widow spiderlings,
according to Walker Van Riper of
the Colorado Museum of Natural
History. Houses have been observed
with black widows behind every
shutter and drain pipe, around the
foundation, in the attics, and in
cellar windows. Although the com-
mon insecticides are ineffective,
a 10 per cent solution of DDT in
kerosene has been proved lethal to
the deadly spider and the effect
has been shown to last for some
time, longer, however, in cool wea-
ther than in hot.
Sugar Synthesis ...
Ordinary table sugar has been syn-
thesized in tiny amounts at the Uni-
versity of California at Berkeley. The
starting materials for the synthesis
were the simple sugars, fructose and
glucose phosphate. These were con-
verted into pure crystals of sucrose,
or comimon cane sugar, when acted
upon by a species of bacteria, Pseu-
domonas saccharophila. According
to the reports, the process has no
commercial value, but it advanced
the knowledge of sugar structure
which may lead to the synthetic pro-
duction of sugar in the future. Main
point of interest here is that sucrose
has been synthesized for the first
time without the aid of plants.
New Cosmetic Case.. ..
Here is an item of interest to
the campus coeds: As protection
against leaking bottles of cosmetics
in traveling bags, a zippered vinyl
plastic case large enough to con-
tain several bottles as well as soap
has been placed in mass produc-
tion. The vinyl copolymer is both
flexible and strong. It is admirably
well-suited for travel as it is light-
weight, waterproof, and resists oil
and grease. It stands up in any cli-
mate and is impervious to heat,
cold, fungi, and, mildew.
Smoke Detectors . .
Two new gas and smoke detecting
instruments have been perfected and
are said to be the most sensitive ever
produced. One, the Ultra-violet Pho-
tometer, which uses ultra-violet light
to detect gases, can discover as little
as one part of gas in a million of air.
Fitted with a'n automatically-record-
ing graph, it is expected to find con-
siderable use in providing continuous
measurement of toxic vapors in fac-
tories, mines, and tunnels. It may re-
place chemical analysis of gases in
closed systems since it does not af-
fect the substances analyzed.
The other instrument is so sen-
sitive that it can register a puff of
cigarette smoke blown into a huge
auditorium. It is known as a Photo-
electric Smoke-Penetrometer. The
equipment gives instantaneous read-
ings on the amount of dust in the air;
hence, the instrument will be uti-
lized in the studies of smoke elimina-
tion, air purification and condition-
ing, and, in addition, it will be used
in studying the concentrations of
various colloidal systems in the field

of chemical research.
Silicones in the News .. .
A silicone fluid is now in pro-
duction in Michighn which is equal
to motor oil in lubricity. It is non-
volatile, and it has no tendency to
become gummy at high tempera-
tures up to 400 degrees F. accord-
ing to a talk by W. R. Collings at a
meeting of the American Institute
of Chemical Engineers. New sili-
cone greases would be ideal for
permanent ball bearing lubrication,
since they exhibit the lowest vola-
tility and greatest heat and oxida-
tion resistance of any known
greases. The name silicone is a
composite of silicon (chief consti-
tuent of sand) and a compound in
organic chemistry. The silicone fa-
mily consists of a large number of
compounds composed of silicon
and carbon compounds, with sili-
con acting to replace carbon in
many instances in the molecule.
Plastics from these organo-silica
compounds have excellent protec-
