State of shock: 200-year-old law about gas mixtures called into question

(University of New Mexico) According to a new study led by a team from The University of New Mexico, centuries-old laws about the behavior of gas mixtures do not apply in the presence of shock waves. This finding could have potential impact on everything that involves mixtures of gases exposed to a shock wave, for example, during combustion in an engine.

Estimates of ecosystem carbon mitigation improved towards the goal of the Paris agreement

(Chiba University) The recent reports from the IPCC concluded that new land-use options to enhance the terrestrial carbon sink are needed to meet the goals of the Paris Agreement on Climate. As a result of the integrated analysis, the research team led by Masayuki Kondo, an Assistant Professor at the Center for Environmental Remote Sensing, Chiba University, succeeded in reducing the mismatches between net CO2 fluxes from multiple data sources. Their results was published on Dec. 12 in Global Change Biology.

SwRI tests fuel delivery device on Blue Origin’s New Shepard vehicle

(Southwest Research Institute) SwRI has received an additional $500,000 in NASA funding to evaluate a device designed to deliver liquid propellant to a rocket engine from fuel tanks. The tapered liquid acquisition device (LAD) is designed to prevent potentially dangerous vapor bubbles from being transferred to the rocket engine. Developed by SwRI engineers and NASA’s Glenn Research Center in Ohio, the new design was tested in a suborbital flight aboard Blue Origin’s New Shepard vehicle on Dec. 10.

Teams of microbes are at work in our bodies. Here’s how to figure out what they’re doing

(Drexel University) An algorithm akin to the annoyingly helpful one that attempts to auto-complete text messages and emails is now being harnessed for a better cause. A group of Drexel University researchers are using its pattern-recognition ability to identify microbial communities in the body by sifting through volumes of genetic code. Their method could speed the development of medical treatments for microbiota-linked ailments like Crohn’s disease.
