A non-Newtonian fluid is one of the more intriguing substances in science. It is a fluid that has a changing viscosity depending on the kind of stress that is applied to it.

All Atoms are made up of protons, neutrons, and electrons. Electrons are negatively charged particles. These orbit the nucleus, similar to the way planets orbit the sun. They are “held together’ to the atom’s nucleus by the electromagnetic forces. Electrons are very, very small—about 1/1000 the...
In biology, metamerism is defined as the property of having repeated structural segments in the body of an organism and is often studied in zoology and developmental biology Metamerism is also a particular psychophysical phenomenon related to color and the perception of color. Sample metamerism...
Polymerization is the process where monomers—or single molecules like amino acids and hydrocarbons—bond to create polymers. There are two kinds of polymers. The first are natural polymers, like deoxyribonucleic acid (or DNA), cellulose and rubber. The second are artificial or man made polymers,...
Teflon is a non-stick coating for pans that was developed by DuPont. Teflon pans are easier to clean and eliminate the need to add oil before sautéing ingredients.

The capillary bed is an interlaced network of capillaries that services an organ. The network size of the capillary bed depends on how active the particular organ is. Usually, the more active organs require more nutrients and produce more waste products. Two kinds of vessels make up the capillary...
Startling results of one of the most extensive studies regarding the illegal drug Ecstasy shows that MDMA won't harm your brain. The study was published during the second week of February in the journal Addiction and found that 3,4-Methylenedioxyethampetamine (MDMA or Ecstasy) will not effect...
