How did bilaterally symmetric flowers evolve from radially symmetric ones?

How did bilaterally symmetric flowers evolve from radially symmetric ones? To address this important question, geneticists Francisco Perfectti and Juan Pedro M. Camacho,...

Rice scientists unveil 'nanoegg'

...' for light to grab hold of," Nordlander said. "In symmetric nanoshells, most of the light energy is lost to these 'dark modes.' With symmetry breaking, we are able to make these dark modes bright by providing dipole moments for more of the incoming light." ...

...e functional morphology. For example, the radially symmetric downy feathers found on chicks and on the trunks o...lts are designed for warmth, while the bilaterally symmetric feathers found on the adult wing are designed for taking flight. What Chuong and his colleagues fo...

Rutgers researchers scientifically link dancing ability to mate quality

Scientists find microRNAs regulate plant development

...particularly struck by the unusual quadrilaterally symmetric seedlings we uncovered in our study. This result implies that the Arabidopsis embryo relies on microRNA restriction of ARF17 activity to achieve normal bilateral symmetry." A second report focuses on the function of the protein ARGONAUTE1 (AGO1), a ...
