Streamlining in Birds Inspires Flight Engineering
Observations show birds are highly streamlined in flight with slender, angled outlines when plucked for study. Feathers supply lightness strength and resilience, shaping the body to reduce drag while providing insulation in cold air.
Germ Free Chickens Hatch From Germless Lab Egg
The Notre Dame biology team led by Prof. James A. Reyniers produced a germ free egg from germ free bantam parents and hatched a germ free chick. Earlier work showed germ free mammals could be bred, but chickens now join a growing list of species able to live germ free and be bred generation to generation.

Structures of Compounds With Electron Bombardment
Cathode-ray stimulated spectroscopy uses electron bombardment to excite organic compounds and reveal molecular structure. At New England Spectrochemical Laboratories two ex astrophysicists, Dr. Daniel Norman and Dr. William Johnson, study solids by analyzing ultraviolet to infrared light emitted when radicals are knocked free by fast electrons. The method preserves the solid state, shows bonding and polymerization, and aids in identifying radicals and detecting patent infringement or curing in resins.

Counterfeiters Found Not Guilty Were Coin Makers Then
Indian scientist Prof. Birbal Sahni concludes bronze coins found near Delhi dating to about 100 B C were produced by a clay mold mint. The process involved heated charcoal treated cylinders and porous molds allowing gas escape as bronze was poured. The discovery, reported in Nature by Dr. F C Thompson, sheds light on ancient Indian coin making and legality.

Petrified Lightning Tubes Form From Heat of Lightning
Science Service describes petrified lightning or fulgurites as fused rock tubes created when lightning heats sand or rock. Found on crags mountain tops sand dunes and in trees these tubes are irregular pointed formations known as fulgurites.
Prehistoric Hopewell Baby Blanket Uncovered in Ohio Cemetery
A richly beaded baby blanket from an Ohio Hopewell burial at Ater Mound near Frankfort is described. Over 1,500 shell beads form a diamond pattern on a two foot six by one foot ten inch fabric, with beads laid in place and later attached to a copper breastplate. The artifact, found during Ohio State Archaeological and Historical Society excavations led by Raymond Baby, shows precise beadwork and pattern replication.
