Dual laser technology reduces brilliant sensing frequency to 200 MHz
This figure shows the Briann gain spectral map obtained along a 13 m single-mode silica fiber. The top diagram shows the tension section of ~1.1 m. The low-color plot shows the corresponding shifts in Brillouin frequencies and confirms distributed strain sensing. Credit: Yokohama National University Scientists have developed a dual-laser Brillouin optical correlation domain reflectometry (BOCDR) system that uses two…

Dramatically reduces the time it takes to measure asteroid distance
The artist’s impression of asteroids near Earth passing through the Earth. The asteroids are there, and they pose a threat to Earth. New ways to determine distances more quickly will help keep us safe. Credit: ESA We all know that asteroids are there, that some of them come dangerously close to Earth, and that they have previously struck Earth with…

A team of chemists from the Scripps Research Institute and Rice University has unveiled a new method that simplifies the synthesis of piperidine, a key structural component of many pharmaceuticals. The study, published in the journal Science, combines biocatalytic carbon-hydrogen oxidation with radical cross-coupling, providing…

Simple enrichment reduces boredom and improves the welfare of farmed dairy cows.
In a new study from JDS Communications, researchers demonstrated that adding new sailing buoys to their pens significantly reduced boredom-related behavior in two dairy cows. Credit: Alison L. Russell Understanding dairy cow behavior has been a hot topic in dairy science research in recent decades. In a special issue of JDS Communications devoted to dairy cow behavior, new research highlights…

Study finds that calcium reduces CO₂ emissions from Arctic soil through mineral formation
Written by Leibniz Zentrum Far Agralandschaftforschung (ZALF) eV Graphical summary. Credit: Environmental Science and Technology (2024). DOI: 10.1021/acs.est.4c07496 In a new study, researchers found that increasing calcium content in soil significantly reduces CO2 emissions. 50% in calcium-poor soils and 57% in calcium-rich soils. The reason is that calcium promotes the formation of the aragonite mineral, which binds CO2 and prevents…
