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.

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.

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.

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.

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.

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.

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? 

Humans have created 8.3 billion metric tons of plastics since large-scale production of the synthetic materials began in the early 1950s, and most of it now resides in landfills or the natural environment according to a study published today in the journal Science Advances.

Seeking to mitigate the greenhouse gas contributions of the region’s agricultural sector, a University of Lethbridge-led study has been granted $1.1 million by the federal government’s Agricultural Greenhouse Gases Program.

“Canadian farmers are great stewards of the land and the environment. These new investments are part of the government’s commitment to addressing climate change and ensuring our farmers are world leaders in the use and development of clean and sustainable technology and processes,” says Lawrence MacAulay, Minister of Agriculture and Agri-Food.

A beam of sunlight streams into your living room, illuminating a Milky Way of dust particles hanging in the air. Although the air looks thick, those visible dust particles are so big that they can’t reach the smallest branches of the respiratory tree in your lungs. It’s the dust we can’t see—smaller than 2.5 microns, called PM 2.5—that can cause allergies and other respiratory problems.
