Human vision inadequate for research on bird vision

The most attractive male birds attract more females and as a result are most successful in terms of reproduction. This is the starting point of many studies looking for factors that influence sexual selection in birds. However, is it reasonable to assume that birds see what we see? In a study published in the latest issue of American Naturalist, Uppsala researchers show that our human vision is not an adequate instrument.

Scientist discovers mechanism that 'silences' unmatched genes during cellular reproduction

When most people discover mold on their bread, they immediately throw it out. Others see a world of possibilities in the tiny fungus. A University of Missouri scientist, along with a collaborative research team, has examined a new mechanism in the reproductive cycle of a certain species of mold.

Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.
