Direct transfer of plant genes from chloroplasts into the cell nucleus
Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. ...

Extensive taste loss in mammals: Animals live in surprisingly different sensory worlds
Scientists from the Monell Center report that seven of 12 related mammalian species have lost the sense of sweet taste. As each of the sweet-blind species eats only meat, the findings demonstrate that a liking ...

Scientists find a key to growth differences between species
The tiny, little-noticed jewel wasp may provide some answers as to how different species differ in size and shape. And that could lead to a better understanding of cell growth regulation, as well as the underlying ...
