Study connects decomposing body’s BMI to surrounding soil microbes

mSphere (2022). DOI: 10.1128/msphere.00325-22″ width=”800″ height=”529″/> During human decomposition, host-associated microbes, environmental microbes, insects, and scavengers work together to break down body tissues. Liquified decomposition products are flushed into soil where microbes respond to the influx and changes in soil chemistry. Antemortem conditions, such as body mass, age, diet, diseases, or drugs and other treatments, … Read more

Physics connects seismic data to properties of rocks and sediments

Credit: NASA/JPL-Caltech A new analysis of seismic data from NASA’s Mars InSight mission has revealed a couple of surprises. The first surprise: the top 300 meters of the subsurface beneath the landing site near the Martian equator contains little or no ice. “We find that Mars’ crust is weak and porous. The sediments are not … Read more
