Insights from experiments at Sandia National Laboratories designed to push chemical systems far from equilibrium allowed an international group of researchers to discover a new major source of formic acid over the Pacific and Indian oceans. The discovery was published in the July 3 issue of Nature Communications. The project was a collaboration among Sandia, the University of New South Wales, the University of Leeds, the University of the Pacific and the University of Minnesota. In addition to being the smallest organic acid and an important chemical for communication among ants, formic acid is the most abundant organic acid in the global atmosphere and a major source of rainwater acidity. However, global atmospheric models significantly underpredict the amount of formic acid present in the troposphere compared to direct measurements. Because formic acid lies at the end point of hydrocarbon oxidation, this underestimate calls into question current scientific understanding of … [Read more...] about Researchers Discover New Source of Formic Acid Over Pacific, Indian Oceans

WASHINGTON--(BUSINESS WIRE)--May 17, 2018--There is a continuing need for practical chip-based sensors that can be used at the point of care to detect cancer and other diseases. An innovative way to inject light into tiny silicon microdisks could help meet this need by bringing down the cost and improving the performance of chip-based biosensors. The advance could eventually lead to a portable and low cost optical sensor for early-stage cancer diagnostics.Microdisks are a type of microscale resonator that use the whispering-gallery optical effect to confine and enhance light that enters the disk. Just as the curved walls of a whispering gallery carry sound waves to allow whispers to be clearly heard across a room, the curved inner surface of a microdisk carries light waves across the disk, enhancing the light. This allows the microdisk to boost a light-based signal coming from a cell, protein or virus of interest, allowing more sensitive detection of subtle changes associated with … [Read more...] about Innovative Light-Delivery Technique Improves Biosensors

Gravitational waves that we can detect here on Earth are generated by the most energetic events in the cosmos, from colliding black holes to merging neutron stars. To spot these space-time ripples, which have traveled billions of light-years in some cases, scientists must build some of the most sensitive equipment the world has ever seen. But the very sensitivity of this gear means that vibrations, turbulence and even gas molecules in our atmosphere can drown out even the most powerful gravitational-wave signals in a crescendo of background noise. Ingenious engineering solutions are therefore needed to pull the weak signal of gravitational waves out of the noise. In new research published in the journal Physical Review Letters, physicists describe a potentially powerful new method that could, theoretically, be used to remove a key component of noise from gravitational-wave detectors and, in doing so, remove the requirement of having to build costly and complex vacuum … [Read more...] about Could This Bold New Technique Boost Gravitational-Wave Detection?
