Why Dinosaurs Had 'Fowl' Breath:
Scientists have discovered how dinosaurs used to breathe in what provides clues to how they evolved and how they might have lived.
Sexist Humor No Laughing Matter, Psychologist Says:
A research project led by a Western Carolina University psychology professor indicates that jokes about blondes and women drivers are not just harmless fun and games; instead, exposure to sexist humor can lead to toleration of hostile feelings and discrimination against women.
Recreational Cocaine Use May Impair Inhibitory Control:
The recreational use of cocaine has rapidly increased in many European countries over the past few years. One cause of this is the fall in the price of the drug on the street from 100 Euros for one gram (about 5 lines) in 2000 to 50 Euros in the Netherlands today. One line of cocaine is, thus, now as cheap as a tablet of ecstasy. This means cocaine is no longer considered an "elite" drug but is affordable for all, especially for recreational use. It is therefore likely that the recreational use of cocaine will become a public health issue in the next few years, which is already the case for the recreational use of ecstasy.
To Fight Disease, Animals -- Like Plants -- Can Tolerate Parasites:
Animals, like plants, can build tolerance to infections at a genetic level, and these findings could provide a better understanding of the epidemiology and evolution of infectious disease, according to evolutionary biologists.
Lack Of Critical Lubricant Causes Wear In Animal Joints:
Mice that don't produce lubricin, a thin film of protein found in the cartilage of joints, showed early wear and higher friction in their joints, a new study led by Brown University researchers shows.
Evolution: When Are Genes 'Adventurous' And When Are They Conservative?:
Taking a chance on an experiment - this is one of the impulses that drive evolution. Living cells are, from this angle, great subjects for experimentation: Changes in one molecule can have all sorts of interesting consequences for many other molecules in the cell. Such experiments on genes and proteins have led the cell, and indeed all life, on a long and fascinating evolutionary journey.
