Using Light to Turn Gut Bacteria Genes On and Off

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.

Pressure-Quenched Silica Glass Reduces Signal Loss in Fiber Optic Cables

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these cables would have less signal loss if it were manufactured under high pressure.

Researchers Succeed in World's First Transmission of 1 Petabit per Second in Multi-Mode Optical Fiber

A group of researchers from the Network System Research Institute of the National Institute of Information and Communications Technology (NICT, Japan) led by Georg Rademacher, NOKIA Bell Labs (Bell Labs, USA) led by Nicolas K. Fontaine and Prysimian Group (Prysimian, France) led by Pierre Sillard succeeded in the world's first transmission exceeding 1 petabit per second in a single-core multi-mode optical fiber. This increases the current record transmission in a multi-mode fiber by a factor of 2.5.
