Opposites do not attract in mating game
Buston and Emlen's study suggests most men and women in Western society look for partners with qualities on a par with their own. Attractive females, for example, are much more likely to seek a similarly healthy and good-looking mate than a rich one. And wealthy males are more likely to seek a rich wife than a pretty one.
Amniotic fluid may hold 'ethical' stem cells
Stem cells may be present in the amniotic fluid that cushions a baby in its mother's womb, suggests a new study.
If these cells prove to have the power to differentiate into different tissue types, they may provide a solution to the ethical dilemma associated with using human embryonic stem cells (ESCs), say reproductive scientists.
Mice succumb to HIV at last
AIDS research could shift into a higher gear thanks to an advance that for the first time allows HIV to fully replicate inside mouse cells.
Researchers at the University of California, San Francisco added a human protein called hp32 to mouse cells to help HIV properly assemble its genome into viral particles. The team is now creating whole mice with the hp32 gene, and looking for other factors that enhance viral infection. |
