Better molded parts through optimum mold cooling
22 October, 2006
Robert Beard of Robert A. Beard & Assoc. Inc. (Kenosha, WI) has seen firsthand the changes the plastics industry is undergoing, and the pain this is causing processors and mold manufacturers alike. In his observation, 80% of the surviving molding companies have taken over the business of the 20% that didn't survive, and now that 20% is going to China. Resin is typically 40% of a molder's cost, and we all know what's happening to resin pricing. For processors to capture and retain work for U.S. plants, increase productivity, and optimize resin usage while reducing costs requires thinking outside the typical moldmaking box.

16 October, 2006
A genetically modified organism is an organism whose genetic material has been altered using techniques in genetics generally known as recombinant DNA technology. Recombinant DNA technology is the ability to combine DNA molecules from different sources into the one molecule in a test tube. Thus, the abilities or the phenotype of the organism, or the proteins it produces, can be altered through the modification of its genes.

Proteins of all sizes and shapes do most of the work in living cells, and the DNA sequences in genes spell out the instructions for making those proteins. The crucial job of reading the genetic instructions and synthesizing the specified proteins is carried out by ribosomes, tiny protein factories humming away inside the cells of all living things.
Allocating HIV drugs to South African cities would prevent the greatest number of infections
16 October, 2006
The most effective way to control the AIDS pandemic in hard-hit South Africa would be to concentrate the allocation of scarce antiretroviral drugs in urban areas. This, however, would not be the most ethical approach, according to an innovative new study from the UCLA AIDS Institute.

Distinguishing friend from foe in the battle against cancer
14 October, 2006
The latest generation of cancer chemotherapeutic drugs specifically targets mutant enzymes or 'oncoproteins' that have run amok and now promote uncontrolled cell growth. As promising as these drugs are, cancer cells with their backs against the wall have the tendency to fight back. A major goal of cancer research is to frustrate these acts of cellular desperation.
