Urban beaches are environmental hotspots for antibiotic resistance after rainfall
A two year study into the prevalence of antibiotic resistance in urban coastal environments shows that some beaches around Sydney have elevated levels of antibiotic resistant (AbR) bacteria following rainfall.

The research highlights the exchange of antibiotic resistant microbes between human waste-water streams and natural ecosystems and a mechanism for potentially significant AbR exposure risk to humans, the researchers say.

The results of the study, published in Water Research, provide clear links between storm-water discharge, which sometimes includes wet-weather sewer overflow (WWSO) events, and the presence of AbR in microorganisms living in urban beach habitats.

The research suggests that stormwater, sewage and urban waste-stream infrastructure, such as pipes, are potential reservoirs and channels for the spread of AbR into natural coastal waters.

The rapid rise of antibiotic resistance within medical, agricultural, urban and natural systems is of major global concern, and is largely a consequence of the mis-use and overuse of antibiotics by humans.

New standard of reference for assessing solar forecast proposed
Being able to accurately forecast how much solar energy reaches the surface of the Earth is key to guiding decisions for running solar power plants.

While day-ahead forecasts have become more accurate in recent years, the solar community lacks a unified verification procedure, and assessing how one forecast compares to another is difficult. New work in the Journal of Renewable and Sustainable Energy, from AIP Publishing, looks to provide a standard of reference to the field.

Researcher Dazhi Yang proposed an improved way to assess day-ahead solar forecasting. The proposed method combines two popular reference methods for weather forecasting, namely persistence and climatology. Using a weighted linear combination of both methods, his approach provides a new way to gauge the skill of a forecaster.

"There is a large collection of solar forecasting works in the literature. However, all papers claim superiority, which is clearly not possible," Yang said. "Without a standardized reference method to gauge forecast accuracy, we cannot compare methods reported in different papers, using different data from different locations and timescales."

Reactor turns greenhouse gas into pure liquid fuel
The catalytic reactor developed by the Rice University lab of chemical and biomolecular engineer Haotian Wang uses carbon dioxide as its feedstock and, in its latest prototype, produces highly purified and high concentrations of formic acid.

Formic acid produced by traditional carbon dioxide devices needs costly and energy-intensive purification steps, Wang said. The direct production of pure formic acid solutions will help to promote commercial carbon dioxide conversion technologies.
....
Wang, who joined Rice's Brown School of Engineering in January, and his group pursue technologies that turn greenhouse gases into useful products. In tests, the new electrocatalyst reached an energy conversion efficiency of about 42%. That means nearly half of the electrical energy can be stored in formic acid as liquid fuel.

"Formic acid is an energy carrier," Wang said. "It's a fuel-cell fuel that can generate electricity and emit carbon dioxide -- which you can grab and recycle again.

"It's also fundamental in the chemical engineering industry as a feedstock for other chemicals, and a storage material for hydrogen that can hold nearly 1,000 times the energy of the same volume of hydrogen gas, which is difficult to compress," he said. "That's currently a big challenge for hydrogen fuel-cell cars."

If powered by renewable energy such as wind and solar such a process could turn CO2 from stationary sources into liquid fuel for fuel cells.

Chemtrail Truthers Are Coming After Greta Thunberg - Daily Beast
Despite their shared interest in the weather, chemtrail believers and climate activists have little common ground. That, according to Peter Ditto, a professor of psychological science studying motivated reasoning at the University of California Irvine, can be chalked up to conservative politics

Ditto said climate denialism often functions "like a team sport." Although there's no moral argument against accepting climate data, "for other reasons, probably economic, the Republican party and conservative thinkers have decided they don't want to believe [climate change], that it's threatening to them," Ditto said. "There's such a team, tribal mentality in the United States right now that people just line up and say, `My side doesn't believe that... believing that is almost tantamount to treason, or betrayal.'"

Polish government plans last-minute push on new coal mining law - Politico.eu
WARSAW -- No matter who wins Poland's election on Sunday, on Monday parliament is set to debate a divisive new law that gives the government additional powers in the process of planning new coal mines.

That's because the ruling Law and Justice (PiS) party government scheduled a parliamentary session immediately after the election to be held by the outgoing parliament's MPs. Although PiS is way ahead in opinion polls, the final outcome is still in doubt -- and the extra-parliamentary session allows the government to push through legislation even if it loses power. The vote on the legislation is due on Tuesday.

The draft mining law gives Warsaw the power to circumvent local governments and communities if it decides that a mining project is important for "the raw material security of the country."

GMWatch | Scientific study drawing attention to the risks of GM mosquitoes comes under attack , 14 Oct
A recent journal article about GM mosquitoes has caused quite a stir. It showed that some of the male mosquitoes that Oxitec Ltd released experimentally in Brazil had successfully interbred with the local mosquito population, and that their hybrid offspring were now spreading and propagating beyond the release area. This despite Oxitec claiming its mosquitoes had a lethal gene that made them "self-limiting".
[...]
But this time there's a difference because the attacks by Oxitec, the company behind the GM mosquitoes, have since been joined by one of the paper's co-authors, biochemist Margareth Capurro from the University of São Paulo in Brazil. Indeed, according to an article for Science, Dissent splits authors of provocative transgenic mosquito study, Capurro isn't just complaining about the paper - she and "several co-authors have reportedly requested that it be retracted".

So who are the paper's authors and why are they apparently at war with each other? The study was conducted by a Yale University team led by population geneticist Jeffrey Powell, who collaborated with Brazilian researchers to collect and analyze DNA from mosquitoes before, during, and after the release of Oxitec's GM mosquitoes. Powell's collaborators included Capurro and colleagues at the University of São Paulo in Brazil, and these appear to be the authors demanding the retraction.
