Coal-tar-based pavement sealant a major source of PAH contamination in Milwaukee streams
December 29, 2016
Runoff from pavement with coal-tar-based sealant is the primary source of toxic polycyclic aromatic hydrocarbons (PAHs) to streambed sediments in Milwaukee, Wisconsin, according to a US Geological Survey and Milwaukee Metropolitan Sewerage District open-access study published in the journal Environmental Toxicology and Chemistry.
Pavement sealant is a black, shiny liquid sprayed or painted on asphalt parking lots, driveways and playgrounds to improve appearance and protect the underlying asphalt. Pavement sealants that contain coal tar, a known human carcinogen, have extremely high levels of PAHs. Some PAHs are toxic to fish and other aquatic life and several are probable human carcinogens.
Honda to show EV concept with AI emotion engine from joint project with Softbank
December 06, 2016
At CES 2017, Honda will showcase what it calls a future technology path toward a redefined mobility experience. The exhibit will include the NeuV, a concept automated EV commuter vehicle equipped with artificial intelligence (AI) called the “emotion engine” that creates new possibilities for human interaction and new value for customers.
The emotion engine is the focus of a joint research project with Softbank Corporation that Honda announced in July 2016 to apply the AI technology in mobility products. (Earlier post.) The “emotion engine” is a set of AI technologies developed by cocoro SB Corp., which enable machines artificially to generate their own emotions.
Global Carbon Project: Low growth in global carbon emissions continues for third successive year
November 14, 2016
Global carbon emissions from burning fossil fuels did not grow in 2015 and are projected to rise only slightly in 2016, marking three years of almost no growth, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project. Decreased use of coal in China is the main reason behind the 3-year slowdown.
The projected rise of only 0.2% for 2016 marks a clear break from the rapid emissions growth of 2.3% per year in the decade to 2013, with just 0.7% growth seen in 2014. The new data shows emissions growth remained below 1% despite GDP growth exceeding 3%. Detailed data were made available in the open-access data journal Earth System Science Data (ESSD). This is the fifth update of the global carbon budget published by ESSD in the living data format.
