Reconstructing the biology of extinct species: A new approach

...perienced field workers used personal knowledge or film of animals in the wild to classify species into one of six locomotor categories ranging from very slow and deliberate to fast and agile. The scientists then compared the canal size of each species to its category of movement. The results reveale...

Researchers create artificial enzyme that mimics the body's internal engine

...lem by attaching the model to a liquid crystalline film on a gold electrode, which provided a nonstop supply of electrons to the model as it transformed oxygen molecules into water-a process called steady turnover. "The biochemists that study the enzyme typically study single turnover," Collman said. "...

Researchers get around this problem by removing the cells from the well and counting them one by one under a microscope. It's a long and tedious process. "Our idea is very simple," Yang said. "We wanted to...

...eriments found that it is not only the size of the film surfaces, but also their shapes, which influence the degree of friction generated. It's remarkable that the degree of friction increases when the surface size decreases, as a result of holes being made in the structure of the film. It is therefore po...
