NASA Mars 2020 to Use Spectroscopy, Fluorescence Imaging in Biosignature Analysis
NASA's Mars 2020 mission, which will look for signs of past life on Mars, will use smart methods originally developed to find the oldest life on Earth. The 2020 mission builds on the successes of prior rovers to make coordinated measurements that could detect signs of ancient life in their original spatial context. These techniques, known as spatially resolved biosignature analysis, derive from geochemical analysis of early life on Earth.

Shrinking FT-NIR Spectrometers Empower Consumers, Businesses
Chip-scale sensor integration has brought us to the edge of new market opportunities that are poised to transform business practices and consumer lifestyles. The ability to incorporate miniaturized sensors into small devices and broad networks means that actionable data can be collected anywhere, anytime. This new capability enables consumers and businesses to monitor goods, conditions and operations in real time and to make changes and adjustments on the fly to optimize safety, health, quality control and production, and even care for the environment.

Spectrometer Uses Silicon Photonics to Monitor Gas Leaks More Efficiently
A chip-based spectrometer that is smaller than a dime has demonstrated the ability to detect methane in concentrations as low as 100 parts-per-million. The spectrometer leverages silicon photonics technology to realize a compact, cost-effective design that provides IR tunable diode-laser absorption spectroscopy (IR-TDLAS) on a CMOS-compatible platform. It uses an approach similar to absorption spectroscopy; but instead of a free-space setup, the laser travels through a narrow silicon waveguide.

Graphene-Based Absorbers Could Enable Ultrafast Lasers in THz Range
A terahertz saturable absorber has been created using printable graphene inks produced by liquid phase exfoliation (LPE) and deposited by transfer coating and ink jet printing. Such an absorber could enable the development of ultrafast lasers in the THz range. These lasers could be useful in applications where short time scale excitation of specific transitions is important, such as time-resolved spectroscopy of gasses and molecules.

Better Beer, Bread Thanks to Supercontinuum Lasers
Most beer is made from four primary ingredients: grains, hops, yeast and water. The basic ingredients for bread are flour, yeast, water and salt. Throw a supercontinuum laser combined with near-IR into the mix and researchers say they can produce better quality beer and healthier bread.
