Surveyed are the etymology and the reason scientists coined a specific name for a newly discovered element. Approaches to naming from a historical viewpoint are considered. (CW)

Describes an experiment to discover the topology of plasma membrane aminophospholipids (phosphatidylethanolamine and phosphatidylserine) using whole platelets and trinitrobenzene sulfonate (TNBS) as a probe. Reports changes in phospholipid distribution during platelet activation with simultaneous action of thrombia and collagen. Details the…

Examined are the illustrations and descriptions of the molecular structure of sulfur dioxide found in selected chemistry textbooks. Inconsistencies and incorrect information are indicated. It is suggested that molecules other than sulfur dioxide be used as examples of molecules for which resonance is important. (CW)

Compares the attributes of the silk from spiders with those of the commercially harvested silk from silkworms. Discusses the evolution, design, and effectiveness of spider webs; the functional mechanics of the varieties of silk that can be produced by the same spider; and the composite, as well as molecular, structure of spider silk thread. (JJK)

Described is a method that can be used to obtain molecular or atomic term symbols. Several examples accompany an explanation of the method. (CW)

Finds that a logical application of the simple rules of the molecular orbital bonding theory for diatomic molecules predicted the existence of three spin isomers of the oxygen molecule: one triplet form with two unpaired electrons and two singlet forms with all electrons paired. (MVL)

Reviews two chemistry software packages: (1) "Organic Reaction Chemistry" (organic chemistry, college level, Apple II); and (2) "Chemical Reactions, Reactions in Aqueous Solution, and Oxidation Reduction Reactions" (general chemistry, college level, IBM). (MVL)
