You Wear Me OutExerting self-control is exhausting. In fact, using self-control in one situation impairs our ability to use self-control in subsequent, even unrelated, situations. What about thinking of other people exerting self-control?

More efficient production of paclitaxelResearch by Michigan State University chemist Kevin Walker is paving the way for potentially cleaner, more efficient production of cancer-fighting paclitaxel - better known as the blockbuster drug Taxol.
First isolated from the bark of the Pacific yew in 1967, paclitaxel has since been made by synthetically modifying an intermediate substance isolated from yew needles using toxic solvents or by fermenting cell cultures.

How to improve the working memory?Psychology experts and neurologists invest considerable effort in the study of working memory. In terms of information retention, there is a difference between long-term memory, which is affected in diseases such as Alzheimer, and short-term or working memory, which allows us to make immediate decisions or structure a discourse. This more ephemeral memory is affected in diseases such as schizophrenia and depression, eventhough a cause-effect........Go to the Neurology news blog (Added on 4/2/2009 5:15:24 AM)
