Chilean scientist plans to clean up mining with ‘metal eating’ bacteria

Starving microorganisms capable of surviving in extreme conditions have already managed to “eat” a nail in just three days.

In Chile, a scientist is testing “metal-eating” bacteria she hopes could help clean up the country’s highly-polluting mining industry.

In her laboratory in Antofagasta, an industrial town 1,100-kilometers north of Santiago, 33-year-old biotechnologist Nadac Reales has been carrying out tests with extremophiles — organisms that live in extreme environments.

Reales came up with her idea while still at university as she was conducting tests at a mining plant using microorganisms to improve the extraction of copper.

“I realized there were various needs in the mining industry, for example what happened with the metallic waste,” she told AFP.

Some metals can be recycled in smelting plants but others, such as HGV truck hoppers that can hold 50 tons of rock, cannot and are often discarded in Chile’s Atacama desert, home to the majority of the country’s mining industry.

Chile is the world’s largest producer of copper, which accounts for up to 15 percent of the country’s GDP, resulting in a lot of mining waste that pollutes the environment.

In her research, Reales, who now runs her own company Rudanac Biotec, concentrated on iron-oxidizing bacteria called Leptospirillum.

She extracted the bacteria from the Tatio geysers located 4,200 meters above sea level, some 350 kilometers from Antofagasta.

The bacteria “live in an acidic environment that is practically unaffected by relatively high concentrations of most metals,” she said.

“At first the bacteria took two months to disintegrate a nail.”

But when starved, they had to adapt and find a way of feeding themselves.

After two years of trials, the result was a marked increase in the speed at which the bacteria “ate,” devouring a nail in just three days.

– Surprising benefit –

Reales says “chemical and microbiological tests” have proved the bacteria are not harmful to humans or the environment.

“We’ve always seen a lot of potential in this project that has already passed an important test in the laboratory,” said Drina Vejar, a microbiologist who is part of a four-person team working with Reales.

“It’s really necessary at this time when we have to plan for a more sustainable development, especially in all these cities with so many polluting industries.”

Mining companies have shown interest in the research but while Rudanac Biotec previously benefitted from a state fund for start-ups, the company needs investment to move on to its next stage of trials.

Reales says she needs money to see if her method will “eat a medium sized beam or a hopper.”

When the disintegration process is complete, what remains is a reddish liquid residue, a solution known as a lixiviant that itself possesses a surprising quality.

“After biodisintegration the product generated (the liquid) can improve the recovery of copper in a process called hydrometallurgy,” said Reales.

Essentially, the liquid residue can be used to extract copper from rock in a more sustainable manner than the current use of chemicals in leaching.

Reales says it means green mining is “totally feasible.”

That is of great interest to mining companies that could use it to improve their large scale extraction of copper or other minerals, while also reducing their pollution, something they are required to do by law.

Reales recently submitted a request for an international patent for her technology, but more importantly she hopes it will help reduce metal waste blotting the landscape in the mining regions of her country.

New York Announces First 2,000 Seats in Universal 2-K Program

The Governor of New York, Kathy Hochul, and New York City Mayor Zohran Mamdani took another step today in their universal early education agenda by announcing the communities that will have access to the first 2,000 seats in the new 2-K program this fall — an initiative backed by a $73 million investment.

The funding is part of the $1.2 billion package previously unveiled by Hochul to strengthen child care and early childhood education across the city, one of the key campaign promises of the now Social Democratic mayor.

At the time of the announcement, the governor also outlined additional funds to reinforce the existing 3-K early education infrastructure, a program launched under former Mayor Bill de Blasio (2014–2021).

When the 2-K initiative was introduced in January, Mayor Mamdani explained that its first phase would offer 2,000 seats, with the goal of eventually expanding into a universal program — a commitment supported by the governor.

State investment in child care and preschool services is expected to increase to $4.5 billion by fiscal year 2027.

Among the first communities set to benefit from the 2,000 seats are Upper Manhattan and Inwood — areas with large Dominican populations — as well as Fordham and Kingsbridge in the Bronx, a borough with a Latino majority.

In East Brooklyn, Canarsie, Brownsville, and Ocean Hill will also be included. Meanwhile, Ozone Park and the Rockaways are among the neighborhoods that will see the rollout of the 2-K program.

Warner Bros. Developing First ‘Game of Thrones’ Movie With ‘Andor’ Writer

Warner Bros. is developing the first feature film based on the hit saga Game of Thrones, with Beau Willimon — screenwriter of Andor — attached to direct, according to a report published Tuesday by Page Six.

The project, currently in early development, will focus on the conquest of King Aegon I Targaryen. A separate television adaptation centered on the same historical storyline within the franchise is also in early stages at HBO.

However, the outlet noted that it remains unclear whether the film will move forward following the recent acquisition of Warner Bros. Discovery by Paramount Skydance.

If the merger is finalized, the movie could potentially be shelved, although that scenario appears unlikely given that the Game of Thrones franchise remains one of HBO’s most valuable and beloved properties.

After six seasons adapting the work of George R. R. Martin, the platform expanded the universe with House of the Dragon, a prequel series set 200 years before the events of Game of Thrones that explores the history of House Targaryen.

Spain’s Prime Minister to Address Nation Amid Trump’s Trade Threats

The Prime Minister of Spain, Pedro Sánchez, will deliver an institutional address this Wednesday at the Moncloa Palace regarding the escalating situation in the Middle East and recent threats directed at Spain by U.S. President Donald Trump.

The Spanish government announced that Sánchez will make a statement at 9:00 a.m. local time to outline his position on the latest developments following the U.S. and Israeli attacks on Iran.

Sánchez is expected to reiterate Spain’s reasons for opposing the use of U.S. military bases on Spanish soil in the operation—an action he has already described as being outside international law—while also expressing criticism of the Iranian regime.

Government sources indicated that the address had been planned prior to Trump’s remarks criticizing Spain’s stance. However, following those comments, Sánchez is now also expected to respond directly to the U.S. president’s statements.

Trump has threatened to “cut all trade with Spain” and said he wants “nothing to do” with the country after Madrid refused to authorize the use of the Morón and Rota military bases in southern Spain for operations against Tehran.

The U.S. president also labeled Spain “a terrible NATO partner” and warned that “no one” would tell him he could not use the facilities.

In response, the Spanish government stated that Spain fulfills its commitments to NATO and European defense. It also warned Trump that any review of bilateral trade relations must respect international law and the agreements in place between the European Union and the United States.
