THE RHYTHM OF LIFE by Arthur J. Snider, pg. 112

The daily activity cycle is just one of many rhythms in man that are regulated by biological clocks.
Bioclocks As Internally Controlled Timers vs. Externally Controlled Timers
Illustration by Richard Borja
A major controversy among those who study biological clocks is whether their cycles
are independent of, or dependent on, external environmental forces.
Chromosome Segments as Biological Clocks / Illustration by Richard Borja
A theory proposed by Charles Ehret and Ernesto Trucco, of the Argonne National Laboratory, says that chromosome segments are circadian clocks. Each segment is made up of many genes that direct the manufacture of proteins through intermediates called messenger-RNAs. In precisely timed steps, RNAs leave the nucleus and produce the genes’ proteins. Each step occurs at the same time each day, and the entire process takes 24 hours.

MAN-MADE ATOMS by Isadore Perlman, pg. 174
The Deep Grip of Spin-2 / Illustrator not identified
The discovery of the spin-2 f° meson hints that if nucleons could be squeezed beyond resistance of the rho forces, they would attract each other with enormous force. This would not only release staggering amounts of usable energy, but should also produce a new kind of matter. The rho’s repulsion, however, does not weaken fast enough to allow this attraction except when two nucleons glance off each other at high speed.
Creating an Element by Bombardment / Illustrator not identified
Addition of protons to a nucleus of an atom results in transmuting the element to a heavier element. In the bombardment technique, ions are driven into the nucleus, above, thereby adding protons directly.
Creating an Element by Bombardment / Lawrence Radiation Laboratory
The ions receive their high energy from devices such as the Heavy Ion Linear Accelerator, viewed from inside the accelerating chamber during modification.
Creating an Element by Irradiation / Oak Ridge National Laboratory
New elements can be formed by irradiation with massive amounts of neutrons. Through beta decay, or loss of electrons, these become protons, transmuting the element to a higher one. This method is carried out with equipment such as the high flux isotope reactor at Oak Ridge National Laboratory where technicians lower the inner cylinder of the fuel assembly. The blue glow from the reactor is caused by radiation.

Seen above are rich illustrations and photographs from a recent salvage store find, the publication Science Year: The World Book Science Annual, 1968. I will be posting further visuals from this book on AQ-V in the near future plus publishing on flickr as well.
