How Absentee Landowners Keep Farmers From Protecting Water And Soil - 0 views

  •  
    The application of network science to biology has advanced our understanding of the metabolism of individual organisms and the organization of ecosystems but has scarcely been applied to life at a planetary scale. To characterize planetary-scale biochemistry, we constructed biochemical networks using a global database of 28,146 annotated genomes and metagenomes and 8658 cataloged biochemical reactions. We uncover scaling laws governing biochemical diversity and network structure shared across levels of organization from individuals to ecosystems, to the biosphere as a whole. Comparing real biochemical reaction networks to random reaction networks reveals that the observed biological scaling is not a product of chemistry alone but instead emerges due to the particular structure of selected reactions commonly participating in living processes. We show that the topology of biochemical networks for the three domains of life is quantitatively distinguishable, with >80% accuracy in predicting evolutionary domain based on biochemical network size and average topology. Together, our results point to a deeper level of organization in biochemical networks than what has been understood so far.

Researchers shed new light on mysteries behind the light emission of fireflies - 0 views

    team of researchers from the NYU Abu Dhabi's (NYUAD) Smart Materials Lab (SML) led by Professor of Chemistry Panče Naumov has conducted a thorough review of the scientific literature surrounding the natural production of light, called bioluminescence, and developed conclusions that will help others in the field direct their research to uncover the mysteries behind this fascinating natural phenomenon.

"The End of Employees" | naked capitalism - 0 views

  • Contracting, like other gig economy jobs, increase insecurity and lower growth. I hate to belabor the obvious, but people who don’t have a steady paycheck are less likely to make major financial commitments, like getting married and setting up a new household, having kids, or even buying consumer durables. However, one industry likely makes out handsomely: Big Pharma, which no doubt winds up selling more brain-chemistry-altering products for the resulting situationally-induced anxiety and/or depression. The short-sightedness of this development on a societal level is breath-taking, yet overwhelmingly pundits celebrate it and political leaders stay mum.
