Electric car subsidies may do more harm than good
June 7, 2017 05:06 PM - Concordia University

Globally, from China and Germany to the United States, electric vehicle (EV) subsidies have been championed as an effective strategy to boost production of renewable technology and reduce greenhouse gas emissions (GHG).

But a new study by Concordia economics professor Ian Irvine shows that subsidizing EVs in the North American context will not reduce GHG emissions in the short-term, and may even increase them — at a cost to taxpayers.

Fungi awake bacteria from their slumber

When a soil dries out, this has a negative impact on the activity of soil bacteria. Using an innovative combination of state-of-the-art analysis and imaging techniques, researchers at UFZ have now discovered that fungi increase the activity of bacteria in dry and nutrient-poor habitats by supplying them with water and nutrients. The ability of fungi to regulate drought stress in soil and thus sustain ecosystem functions is an important insight in the context of climate change.

Motor-boat noise makes fish bad parents, leading to the death of their babies
June 7, 2017 08:12 AM - University of Exeter

Noise from motorboats is making fish become bad parents, and reducing the chance of their young surviving, research led by marine experts at the University of Exeter has shown.

The sound of motorboat engines disturbed coral reef fish so acutely it changed the behaviour of parents, and stopped male fish properly guarding their young, feeding and interacting with their offspring.

UT Austin, Environmental Defense Fund, Google and Aclima Unveil New Hyper-Local Air Pollution Map
June 5, 2017 10:30 AM - University of Texas at Austin

Engineering researchers at The University of Texas at Austin have developed the most detailed and extensive local map of air pollution ever produced for an urban area, using specially equipped Google Street View cars to measure air quality on a block-by-block basis. This new hyper-local mobile approach to measuring air quality, which reveals that air pollution can vary dramatically even within a single city block, could address major air quality monitoring gaps worldwide.

Unconventional Oil and Gas Production Not Currently Affecting Drinking Water Quality
June 5, 2017 08:06 AM - USGS

Decades or longer may be needed to fully assess the effects of unconventional oil and gas production on the quality of groundwater used for drinking water in Arkansas, Louisiana, and Texas

A new U.S. Geological Survey study shows that unconventional oil and gas production in some areas of Arkansas, Louisiana, and Texas is not currently a significant source of methane or benzene to drinking water wells. These production areas include the Eagle Ford, Fayetteville, and Haynesville shale formations, which are some of the largest sources of natural gas in the country and have trillions of cubic feet of gas.

Even Elon Musk May Not Be Able to Make an Electric Truck Work
June 1, 2017 09:40 AM - Eric Adams via Wired

It's been nearly a year since Elon Musk revealed his intention to electrify the world’s roads with buses and trucks in addition to Tesla’s passenger cars. He hasn’t said much about the 18-wheeler—a proper unveil is set for September—except that it will use same motors as the upcoming Model 3, and that it would, of course, disrupt an industry that generates one quarter of US transportation-related greenhouse gas emissions.

Human Activity has Polluted European Air for 2000 Years, Study Finds
June 1, 2017 07:20 AM - American Geophysical Union

A new study combining European ice core data and historical records of the infamous Black Death pandemic of 1349-1353 shows metal mining and smelting have polluted the environment for thousands of years, challenging the widespread belief that environmental pollution began with the Industrial Revolution in the 1700s and 1800s.
