...Cornell researchers, a young Israeli chemist named Akiba Bar-Nun and his biochemist wife Nurit, tested the theory in a relatively simple experiment. They filled one end of a brass-and-Pyrex tube with a mixture of ammonia, methane, ethane and water vapor-all probable ingredients of the earth's early atmosphere. A thin plastic membrane separated the gases from the other end of the tube, which contained chemically inert helium. The Bar-Nuns increased the helium pressure until the membrane broke. This produced a shock wave that swept into the gaseous mixture at high speed, momentarily creating temperatures...
...chemist and now to the psychiatrist, lithium is a fascinating substance, the lightest of all the solid elements. Its compounds have had a discouraging history in medicine.

Most detergents contain phosphates, which are linked to excessive growth of algae in water. These algae can choke off wildlife in streams and lakes.

However, both products contain essentially the same ingredients -enzymes, phosphates and surfactant, a cleaning agent...
...Dancer's Image from first place to last in the 1968 Kentucky Derby caused a controversy still unsettled in the courts. Was Dancer's Image given butazolidin within the forbidden pre- race period? Peter Fuller and company argued that the test was inconclusive and the competence of the chemist was suspect. The State Racing Commission argued that the test was adequate and that if the stable hands were not guilty of administering the pain-killing drug to the horse, they were at least guilty of negligence in the care of the horse-witness the suspension of the trainer...
