The article focuses on the efficiency of miniature stretchable dye laser in spectroscopy. These lasers had been developed for use in the visible spectrum. With this, researchers at the California Institute of Technology in Pasadena, California have created a stretchable optofluidic dye or commonly known as laser on a chip. It is made of polydimethysiloxane polymer that changes the period of distributed-feedback geometry of the device.

Focuses on the study which found that energy-transfer pathways in the photosynthesis process appear to be affected by molecular factors that had not previously been considered, conducted by researchers at the University of California-Berkeley and Lawrence Berkeley National Laboratory in Berkeley, California. Use of 2-D spectroscopy to view the direct and highly detailed observation of the process; Comparison between 2-D spectroscopy and the Fenna-Matthews-Olson photosynthetic protein which is often used to study the photosynthesis process; Implications of the results which calls for further study of photosynthesis and broader use of the technique.

The article focuses on the experiment that demonstrates negative refraction in negative-index materials (NIMs) operating in the microwave regime conducted by researchers at the California Institute of Technology. The investigators have shown such refraction in the blue-green region of the visible spectrum. A material based on a metal-insulator-metal waveguide that serves as a two-dimensional NIM with an electric permittivity and magnetic permeability is being used in the study.

The article focuses on the development of a rugged ethylene monitor based on cavity ring-down spectroscopy by the researchers at the Picarro in Sunnyvale, and Ethylene Controls in Selma, California. The tool can measure ethylene to parts per billion volume. The researchers noted that ethylene gas affects the ripening of fruits and vegetables which has been called the death hormone for its role in pushing fruit toward senescence.
