Newly recognized gene mutation may reduce seeds, resurrect plants

...t Environmental Stress Physiology. "When I went to throw it away, I noticed it had small shoots coming up as if it had returned to life."

Ghost protein leaves fresh tracks in the cell

...Dubreuil reworked his hypothesis. "We decided to throw out our assumptions and start fresh," he said. A laboratory fly was genetically engineered so that spectrin could no longer bind to ankyrin -- which, Dubreuil assumed, meant that spectrin should no longer attach to the membrane. "We thought that ...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency
