Australia is Building a 1,250-Mile Highway for Electric Vehicles
July 27, 2017 04:54 PM - Yale Environment 360

Australia will install 18 electric vehicle fast-charging stations along a nearly 1,250-mile stretch of coastal highway in Queensland, creating one of the world’s longest EV roadways, Reuters reported

The network, which will cost $3 million to build and open within six months, will stretch from Cairns to Coolangatta and west to Toowoomba, running parallel to the Great Barrier Reef. The charging stations will power a vehicle in 30 minutes. Drivers will be able to charge their vehicles for free for at least a year.

Preterm Birth & Low Birth Weight Linked to Air Pollution Exposure Early in Pregnancy, Study Finds
July 27, 2017 11:25 AM - NYU Langone Health / NYU School of Medicine

Exposure to air pollution early in a pregnancy could increase risk for preterm birth and low birth weight, according to a study led by researchers at NYU School of Medicine, and published on July 27 in Environmental Health Perspectives.

Heavy metals in water meet their match
July 27, 2017 08:46 AM - Rice University

Carbon nanotubes immobilized in a tuft of quartz fiber have the power to remove toxic heavy metals from water, according to researchers at Rice University.

Prize-winning filters produced in the lab of Rice chemist Andrew Barron by then-high school student and lead author Perry Alagappan absorb more than 99 percent of metals from samples laden with cadmium, cobalt, copper, mercury, nickel and lead. Once saturated, the filters can be washed with a mild household chemical like vinegar and reused.

The researchers calculated one gram of the material could treat 83,000 liters of contaminated water to meet World Health Organization standards — enough to supply the daily needs of 11,000 people.

New membranes help reduce carbon dioxide emission

The University of Twente and the German Research Centre Jülich are collaborating on developing membranes for an efficient separation of gasses, to use for the production of oxygen or hydrogen, for example.

TOXIC TAX Motorists face rush-hour bans and pollution taxes as part of the Government's war on 'dirty' roads
July 25, 2017 04:55 PM - Steve Hawkes

MOTORISTS face rush-hour bans and pollution taxes in up to 17 towns and cities across the UK as the Government vows to clean up the ‘dirtiest roads’ in Britain.

Environment Secretary Michael Gove will pave the way for local authorities to slap yet more tax on drivers as part of his radical blueprint.

His plans reveal that air pollution needs to be addressed on 81 roads – 33 of which are outside London such as the A360 in Sheffield or A35 in Southampton.

Nitrogen dioxide emissions along each of them breach the legal limit.

Mr Gove will insist that councils first exhaust all other possible options to improve air quality, such as tackling chronic congestion.

The Coast Is Not So Clear
July 24, 2017 01:18 PM - University of California - Santa Barbara

For nearly a century, the O’Shaughnessy seawall has held back the sand and seas of San Francisco’s Ocean Beach. At work even longer: the Galveston seawall, built after America’s deadliest hurricane in 1900 killed thousands in Texas.

Allowable 'carbon budget' most likely overestimated
July 24, 2017 12:32 PM - Andrea Elyse Messer, Pennsylvania State University

While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define "pre-industrial" to be in the late 1800's, a true non-industrially influenced baseline is probably further in the past, according to an international team of researchers who are concerned because it affects the available carbon budget for meeting the 2 degrees Celsius (3.6 degrees Fahrenheit) warming limit agreed to in the Paris Conference of 2015.

The spirit of collaboration aboard Gulf of Mexico cruise
July 24, 2017 08:23 AM - NOAA

This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of Mexico yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through international waters with 24 scientists from the United States, Mexico and Cuba on board.

Scientists Uncover Biogeochemical Controls on Occurrence and Distribution of PACs in Coals
July 21, 2017 09:56 AM - University of Science and Technology of China

The organic matter in coal contains polycyclic aromatic compounds (PACs) of varying quantities in diverse soluble and insoluble forms. PACs in coal are of special interest for organic geochemical studies as they have been successfully used as biological marker compounds (biomarkers) and indicators of thermal maturity.

However, challenges exist when applying PACs in understanding the organic geochemistry of coal. For example, what are the sources of PACs in coals? How do they transform during the long-term coal-formation history? Is there any regular relationship between the PAC and macro-molecular structural changes?
