...Discovery that all elements are built up from hydrogen...
...nearly every layman knows, hydrogen is 8% more buoyant than helium, but is in disfavor for use in dirigibles because: 1) it is explosive and 2) it seeps through the fabric about 50% faster than helium. Last week the Navy Bureau of Aeronautics made known that a mixture of 90% helium and 10% hydrogen may be developed for the Navy's new superdirigibles ZRS-4 and ZRS-5. Such a mixture, suggested by German scientists, would enable a ship of that size (6,500,000 cu. ft. inflation) to carry 25 additional persons.† More important...
There lies the main obstacle to the plan: the problem of re-purification of the combined gases. Experimenters now propose passing the polluted gas under pressure over copper oxide, which would act as a catalytic agent and cause the hydrogen and oxygen to form water...
...Gross lift of the ZRS-4 with helium: 402,000 lb. With hydrogen: 442,000 lb. With 90-10 mixture...
...Crile's experiment toward creating living material out of dead is highly exciting. Basic material of all beings is protoplasm. Every body cell contains protoplasm, a gooey material like white of egg, one-fourth heavier than water. Protoplasm always contains at least twelve elements: calcium, carbon, chlorine, hydrogen, iron, magnesium, nitrogen, oxygen, phosphorus, potassium, sodium, sulphur. The living combination of these is exceedingly complex. Best of chemists have been unable to decipher the protoplasmic interrelations. Could they do "so, they could make protoplasm in their laboratories...
