Giving photons their marching orders

Giving photons their marching orders

Researchers in the School of Engineering & Applied Science have found a way to give photons, or light packets, their marching orders. The researchers have capitalized on the largesse of an energy state in an optical field to make photons in their lasing system travel in a consistent mode, either clockwise or counterclockwise.

Turning humidity into clean drinking water

Social venture WOOTA (Water Out Of Thin Air) is the winner of this year’s School of Engineering & Applied Science’s annual Engineering Discovery Competition (EDC) and will receive $20,000 in cash, as well as $5,000 in legal services from Polsinelli for building a device that turns humidity in the air into clean drinking water.
How to stop dividing cancer cells in their tracks

How to stop dividing cancer cells in their tracks

Researchers from Washington University in St. Louis and St. Jude Children’s Research Hospital in Memphis made a discovery that uncovers the molecular logic of how dividing cells are stopped in their tracks. The team zeroed in on a specific protein, whose job is to stop a cell from dividing or to slow the division.
