If intelligent and more advanced civilizations exist on other planets then its a good bet that some of these civilizations turned to asteroid mining long ago. If so, the hallmarks of their mining activities, such as unusual dirty halos of cast-off dust and debris around large asteroids, might be detectable from earth.

A novel approach for finding and evaluating structural models of small metallic nanoparticles is presented. Rather than fitting a single model with many degrees of freedom, libraries of clusters from multiple structural motifs are built algorithmically and individually refined against experimental pair distribution functions. Each cluster fit is highly constrained. The approach, called cluster-mining, returns all candidate structure models that are consistent with the data as measured by a goodness of fit. It is highly automated, easy to use, and yields models that are more physically realistic and result in better agreement to the data than models based on cubic close-packed crystallographic cores, often reported in the literature for metallic nanoparticles.

A new approach is presented to obtain candidate structures from atomic pair distribution function (PDF) data in a highly automated way. It fetches, from web-based structural databases, all the structures meeting the experimenter's search criteria and performs structure refinements on them without human intervention. It supports both X-ray and neutron PDFs. Tests on various material systems show the effectiveness and robustness of the algorithm in finding the correct atomic crystal structure. It works on crystalline and nanocrystalline materials including complex oxide nanoparticles and nanowires, low-symmetry and locally distorted structures, and complicated doped and magnetic materials. This approach could greatly reduce the traditional structure searching work and enable the possibility of high-throughput real-time auto-analysis PDF experiments in the future.

The Trump administration has finalized its rollback of a major Obama-era climate policy, weakening auto emissions standards in a move it says will mean cheaper cars for consumers.

"By making newer, safer, and cleaner vehicles more accessible for American families, more lives will be saved and more jobs will be created," U.S. Secretary of Transportation Elaine L. Chao said in a statement.

But consumer watchdog organizations, environmental groups and even the Environmental Protection Agency's own scientific advisory board have raised concerns about that rationale, saying the weakened standards will lead to dirtier air and cost consumers at the gas pump long-term.

Environmental Protection Agency administrator Andrew Wheeler called the new rule a move to "correct" greenhouse gas emissions standards that were costly for automakers to comply with.

"Our final rule...strikes the right regulatory balance that protects our environment, and sets reasonable targets for the auto industry," Wheeler said in a statement.

The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule will toughen carbon dioxide emissions standards by 1.5% a year through model year 2026, compared to about 5% a year under the Obama policy.

The Trump administration originally proposed freezing the standards altogether without any increase. It modified the rule after push back from not only environmental groups but also some automakers, who worried they will be out of step in a global marketplace increasingly geared toward lower emission cars and trucks.

Still, critics say the new rule will lead to nearly a billion additional metric tons of climate warming CO2 in the atmosphere, and that consumers will end up losing money by buying about 80 billion more gallons of gas.

"This rule will lead to dirtier air at a time when our country is working around the clock to respond to a respiratory pandemic whose effects may be exacerbated by air pollution," said U.S. Senator Tom Carper (D-Del.) in a statement. He's the top Democrat on the Senate Environment and Public Works Committee.

The Trump administration asserts the new rule will save lives because Americans will buy newer, safer vehicles. But Carper points out that its own analysis finds there would be even more premature deaths from increased air pollution.

For that reason and others, the new standards are sure to face legal challenges. In fact, even the Trump administration's own science advisers have said "there are significant weaknesses in the scientific analysis of the proposed rule."

"The rollback of the vehicle emissions standards is based on analysis that is shoddy even by the shockingly unprofessional standards of Trump-era deregulation," said Richard Revesz of the Institute for Policy Integrity and Dean Emeritus at New York University School of Law.

California and other states are also likely to file suit against the rule. They've asserted their long-standing right to set their own, stricter emissions standards, something the Trump administration has also challenged.

A worst case scenario for automakers would be different standards in different states. The new policy may ultimately be decided by the U.S. Supreme Court, but the uncertainty waiting for that would exact its own toll on an industry that must plan years ahead.

Thomas Pyle, President of the American Energy Alliance, welcomed the new standards. In a statement, he said the Obama-era mandate was "impossible to achieve without dramatically altering the automobile market or making the cost of vehicles out of reach for most American families. This new... rule will make cars more affordable for consumers at a time when they need it most."

The Trump administration has been pushing ahead with a number of environmental rollbacks, aiming to finalize them well ahead of November's election. That would make it harder for a Democratic president, if one were elected, to reverse them again.

As Los Angeles mulls a law that would raise the minimum wage above the current California minimum of $9 an hour, it's the latest city to jump on a trend that started as the by-product of a failed labor negotiation in the state of Washington.

The first city to enact a $15-per-hour minimum wage was SeaTac, Wash., — a tiny airport town outside Seattle. "SeaTac will be viewed someday as the vanguard, as the place where the fight started," the lead organizer of SeaTac's $15 campaign, David Rolf, told supporters in November 2013 after a ballot measure there barely passed.

Rolf never set out to raise SeaTac’s minimum wage, much less start a national movement. Speaking from a sparse corner office in downtown Seattle at the Service Employees International Union 775, which he founded in 2002, Rolf told KPCC that his original goal in 2010 was to unionize workers at SeaTac airport.

When employers – led by Alaska Airlines — played hardball, Rolf put the $15 minimum wage on the ballot as leverage. “We had some polling in SeaTac that it could pass, but it was not at all definitive,” Rolf said.

That proved prescient: In a city of just 12,108 registered voters, Rolf's staff signed up around 1,000 new voters, many of them immigrants who had never cast a ballot. The measure won by just 77 votes.

It's an irony that the new law doesn't apply to workers at the center of the minimum wage campaign: The airport workers at SeaTac. That's because the Port of Seattle, which oversees the airport, challenged the initiative, arguing that the city's new minimum wage should not apply to the nearly 5,000 workers at the airport. A county judge agreed. Supporters of the $15 wage have appealed.

Still, Rolf said, "I think people are proud that that’s what happening. There are leaders of the movement in Seattle, including our mayor, that said shortly after the victory, 'Now we have to take it everywhere else.'"

The $15 minimum wage spread to Seattle last June and to San Francisco in November. 

Why $15 an hour?

The $15 figure first came to people’s attention in a series of strikes by fast food workers that started two years ago in New York. 

“I think it’s aspirational, and it provides a clean and easy-to-understand number," Rolf said. "You can debate whether it ought to really be $14.89 or $17.12, and based upon the cost of living in different cities, you could have a different answer. But in the late 19th and early 20th century, American workers didn’t rally for 7.9 or 8.1 hour working day. They rallied for an eight-hour day.”

“What’s really remarkable about social protest movements in American history is that the radical ideas of one group are often the common sense ideas of another group in a matter of a few years," said Peter Dreier, professor of politics at Occidental College.

Rolf is hopeful the $15 minimum wage can spread to every state. But Nelson Lichtenstein, Director of the Center for the Study of Work, Labor and Democracy at the University of California, Santa Barbara, is skeptical.

“I don’t think having high wages in a few cities will mean it will spread to red state America,” he said. 

Lichtenstein said cities like L.A. have become more labor friendly, thanks largely to an influx of immigrants, but that’s not the case in the South. Oklahoma recently banned any city from setting its own minimum wage, joining at least 12 other states with similar laws, according to Paul Sonn, general counsel and program director at the National Employment Law Project.

In November, voters in four Republican-leaning states — Alaska, Arkansas, South Dakota, and Nebraska — approved higher minimum wages, but they weren’t close to $15.

A $15 dollar wage would have a much greater impact in Los Angeles than Seattle or San Francisco because the average income here is much lower than in those cities. Post-recession, income inequality has become much more of a concern for voters, which has made $15 more palatable, Sonn said.

This fall, the Los Angeles City Council enacted a $15.37 minimum wage for hotel workers that takes effect next year. A similar law has been in effect around LAX since 2007. 

But even though California cities have been allowed to set their own minimum wages for more than a decade, L.A. has never come close to doing so.

Until now.

“Union members and non-union members have a strong interest in seeing our economy grow," said Rusty Hicks, the new head of the Los Angeles County Federation of Labor, which represents over 300 unions.; Credit: Ben Bergman/KPCC

Labor unions have led the fight to raise the minimum wage in several American cities, including Los Angeles, where the City Council is considering two proposals right now that would give raises to hundreds of thousands of workers (to $13.25 an hour by 2017 and $15.25 an hour by 2019).

But few of the unions' members have benefited directly from the initiatives. So why do unions care about a $15 wage for non-union workers? 

It’s part of a long-term strategy to protect the interests of their members, labor leaders say. They also see an opportunity to raise the profile of unions after years of falling membership.

"We can’t be the movement that’s just about us," said David Rolf, an international vice-president of SEIU, who led the first successful $15 minimum wage campaign in SeaTac, the town in Washington that is home to the region's similarly named airport. 

“We have to be the movement that’s about justice for all," Rolf added. "The labor movement that people flocked to by the tens of millions in the 1930s wasn’t known for fighting for 500-page contracts. They were known for fighting for the eight-hour day, fighting to end child labor.”

The idea that workers should earn $15 dollars an hour first came to the public’s attention during a series of fast food strikes that started in New York City in late 2012. Those workers didn’t just walk off the job by themselves. They were part of a campaign organized by unions, led by SEIU, which is made up mostly of public sector and health care workers.

$10 million fast-food strikes

The Service Employees International Union spent $10 million dollars on the fast food strikes, according to The New York Times. But none of those restaurants have unionized, and because it’s been so hard to form private sector union these days, they probably never will, said labor historian Nelson Lichtenstein.

“In effect what you have now is the SEIU – its hospital membership or its members working at the Department of Motor Vehicles – helping to raise the wages of fast food workers, but not their own wages,” Lichtenstein said.

That's because unionized workers earn far more than the current or proposed new minimum wages, in L.A. an average of more than $27 an hour, according to UCLA's Center for Research on Employment and Labor. 

The spread of the $15 minimum wage from SeaTac to Seattle to San Francisco — and now possibly Los Angeles — is a huge victory for labor unions, but it’s unlikely most of the people getting raises will ever be part of organized labor.

Still, the rank and file seem to support their unions' efforts.

“I personally support using our organization as a way to advocate for those who don’t have a voice," said Rafael Sanchez III, a teacher's assistant at Bell High School who's a member of SEIU Local 99. 

A challenging time for the labor movement

In the 1950’s, about one in three American workers belonged to a union. Last year, just 11 percent did – or 6 percent of private sector workers – the lowest numbers in nearly a century.

Rolf says the minimum wage campaigns mark a change in tactics for organized labor; Rather than the shop floor, the focus is on the ballot box and city hall.

“Since at least the 1980s, winning unions in the private sector has been a Herculean task," Rolf said. "The political process provides an alternative vehicle.”

And an increasingly successful one. It was voters who approved the first $15 wage, in Washington state in 2013, and another one in San Francisco last year.  

In Los Angeles, the issue is before the city council. Mayor Eric Garcetti opened the bidding, proposing a raise of $13.25 on Labor Day before six council members countered with $15.25.

The Los Angeles County Federation of Labor – lead by Rusty Hicks — is pushing for the higher option.

“Union members and non-union members have an interest in seeing our economy grow," said Hicks. "You can’t continue to have a strong, vibrant economy if in fact folks don’t have money in their pockets.”

Other benefits for unions: A safety net and a higher floor

Some union members see a higher minimum wage as a safety net.

Robert Matsuda is a studio violinist represented by the American Federation of Musicians, part of the AFL-CIO. Even though he’s not working for the minimum wage now, he worries that may not last: He’s getting fewer and fewer gigs as more film and TV scoring is outsourced overseas.

“I might have to take a minimum wage job in the near future, so it might directly affect me,” said Matsuda.

There’s also a more tangible benefit for unions, says Nelson Lichtenstein, the labor historian: A higher minimum wage means a higher wage floor to negotiate with in future contracts.

“It’s one labor market, and if you can raise the wages in those sectors that have been pulling down the general wage level – i.e: fast food and retail – then it makes it easier for unions to create a higher standard and go on and get more stuff,” said Lichtenstein.

On Friday morning, union members will rally in front of Los Angeles City Hall, calling on the council to enact a $15.25 an hour minimum wage as soon as possible.

In 1989, researchers dragged a plough harrow across the seafloor of the Peru Basin to recreate some of the effects of deep-sea mining. Twenty-six years later, a new team of researchers returned to the site to assess whether there were any long-term ecological effects. They found that the seabed ecosystem remained disrupted, with significantly fewer suspension feeder species, such as anemones and sea sponges, than in undisturbed areas of seafloor. This suggests that deep-sea mining could cause irreversible changes to marine food webs in highly disturbed areas.

Globally, up to 27% of all steel and 33% of all aluminium could potentially be reused, according to research. Significant barriers to reuse, such as component incompatibility between products and metal corrosion, must first be addressed if these reuse figures are to be achieved.

Mining metals from landfill sites can be economically viable, a recent project in the US has demonstrated. Approximately 34 352 tonnes of metals, conservatively valued at US$7.42 million (€6.67 million) were recovered from the 8 hectare ashfill site, according to researchers who analysed the project.

The potential of recycling aluminium scrap in Austria has been modelled in a new study. A surplus of mixed aluminium scrap is expected by 2045 if no advanced sorting technologies are applied. Increased demand for wrought aluminium alloys could mean this surplus occurs sooner. New methods to intensively sort aluminium could prevent this excess and contribute towards REACH1 recycling and climate targets.

Identifying emerging research areas and technologies is important for decision makers, but notoriously difficult to do. This study presents a new way of searching the literature to identify emerging topics, which will help policymakers, industry and funding bodies to make better decisions.

Administrative sanctions against environmental crime, such as fines, are generally easier and cheaper to implement than criminal punishment methods, such as prison sentences. This study explored enforcement methods for environmental crime in four Western European areas: Flanders (Belgium), Germany, the Netherlands and the UK. Based on their findings, the authors say it is most cost-effective — and may increase deterrence — to use both forms of enforcement.

To restore a river site to good ecological status involves comparing it to similar sites that have been far less affected by human activity. A recent study has established a set of guidelines that define an acceptable level of human pressure that can be used to identify these minimally disturbed sites and ensure consistent ecological assessment among EU Member States.

“We recommend allowing all physical shops dealing on sales, repair and service activity of mobile phones, mobile devices (laptops and tablets) and their supporting accessories to be opened on a limited basis (three days a week for five hours) with limited number of staff,” AIMRA said in an April 17 letter to union home minister Amit Shah.

Although the value of biodiversity and ecosystem services has been recognised, it is still not fully integrated into policy-making. A new report has developed an action plan that recommends that governments create a 'Natural Capital' minister in the Finance Ministry, develop a set of Natural Capital Accounts and form an inter-departmental committee to oversee programmes in this area.

A briefing document, providing policymakers with key information on environmental impact assessments of deep-sea mining, has been published. The authors describe the Environmental Impact Assessment (EIA) process in detail to aid management and policy decisions regarding these sensitive habitats.

Gold mining areas in the Peruvian Amazon rainforest expanded from under 10 000 hectares in 1999 to over 50 000 hectares by 2012, and now destroys more forest than agriculture and logging combined, new research has shown. Using high-resolution satellite imaging, researchers estimated gold mining areas to be twice as large as estimated by previous studies, which did not include the combined effects of thousands of small, mainly illicit, mining operations.

Emissions of the greenhouse gases (GHGs) tetrafluoromethane (TFM) and hexafluoroethane (HFE) reported by industry accounted for only around half actual levels measured in the atmosphere between 2002 and 2010, new research reveals. The semiconductor and aluminium production industries, the two main sources of these gases, have reported success in their voluntary efforts to control these emissions. However, this does not match ‘top-down’ atmospheric monitoring, the researchers say.
