A pickle-shaped root is revealing how plants develop from embryos to adults and also may hold answers about cancer cell growth.

Purdue University researchers have uncovered nine specific genes that are shut off before plants make the developmental transition from the embryonic stage to adulthood. Results of the latest study are published in the July issue of The Plant Journal.
"We now have data supporting the hypothesis that the gene PKL is a master regulator of genes that promote embryonic identity," said Joe Ogas, an associate professor of biochemistry. "Some of the genes we identified are known to control plant embryo development. They tell the plant, be a seed. Then PKL says, Youre done being a seed, and turns them off."

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
