(PhysOrg.com) -- Using photons instead of electrons to transmit information could lead to faster and more secure ways to communicate, among other advantages. Now a team of physicists has taken another step toward realizing quantum photonic technologies by demonstrating how to quickly manipulate single photons at the same wavelengths used in existing optical telecommunications networks. The ability to control a photon’s path and polarization in the time of a few nanoseconds could allow photonic circuits to be integrated with existing optical telecom networks, leading to significant improvements.

The EPA took another step toward tightening oversight of hydraulic fracturing today, announcing it would initiate a process to set national rules for treating wastewater discharged from gas drilling operations. Until now, the agency has largely left it to states to police wastewater discharges. Some have allowed drillers to pump waste through sewage treatment plants that aren't equipped to remove many of the contaminants, leading to pollution in some rivers and to problems at drinking water facilities.

Regular, easy running for fitness can be a boon to health and wellbeing, but experts say for safety, joggers especially must keep a spring in their step and an eye on how that foot falls.
