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.

Epstein Denies Being ‘the Devil’ in Newly Released Video Interview

Jeffrey Epstein claims he was the least dangerous type of sex offender and denied being “the devil” in a video interview included in the latest batch of documents released over the weekend by the U.S. Department of Justice.

The roughly two-hour interview was conducted by Steve Bannon, a former adviser to U.S. President Donald Trump, and appears to have been recorded at the late financier’s New York residence on an unknown date.

Epstein died by suicide in 2019 while in jail awaiting trial on sex trafficking charges involving minors. Since December, the U.S. government has released millions of documents related to the case under transparency laws.

“Do you think you’re the devil incarnate?” Bannon asks Epstein in the video interview revealed in the latest release.

“No, but I do have a good mirror,” Epstein replies with a smile, wearing a black shirt and glasses. When pressed again, he adds, “I don’t know. Why would you say that?”

Epstein, who pleaded guilty in 2008 to soliciting a minor for prostitution, also appears to downplay the seriousness of his conviction.

He objects when Bannon refers to him as a “Level Three sexual predator,” a classification in the United States indicating a very serious threat to public safety.

“No, I’m the lowest,” Epstein says.

“But still an offender,” Bannon responds.

“Yes,” Epstein replies.

The exchange comes after Bannon asks Epstein whether he considers his wealth to be “dirty,” suggesting it was earned by advising “the worst people in the world.”

Epstein insists that he made his money legally, while acknowledging that “ethics is always a complicated issue.”

He claims he donated money to help eradicate polio in Pakistan and India, apparently in an attempt to justify the origins of his fortune.

The documents also show that Bannon maintained regular correspondence with Epstein, who offered to help the far-right political figure spread his conservative ideology in Europe.

Since Trump took office in January 2025, U.S. authorities have released millions of pages related to Epstein, along with photos and videos.

These materials have shed new light on Epstein’s ties to high-profile business executives such as Microsoft co-founder Bill Gates, celebrities including filmmaker Woody Allen, and academics and political figures, among them Trump and former President Bill Clinton.

Hypothermia Linked to Most Deaths During New York’s Recent Cold Spell

Hypothermia “played a role” in 13 of the 16 deaths recorded in New York City during the recent period of extreme cold, Mayor Mandami said at a press conference. Three of the deaths were classified as drug overdoses.

None of the individuals were sleeping on the streets at the time of their deaths, the mayor added, noting that some had previously been in contact with emergency shelter services.

Mandami said the city has activated emergency warming centers and deployed a fleet of 20 vehicles staffed with medical personnel to respond to the cold weather crisis.

“As of this morning, we have made more than 930 referrals to shelters and safe facilities. We have also involuntarily transported 18 New Yorkers who were deemed a danger to themselves or others,” he said.

According to official statistics, New York City recorded between nine and 27 cold-related deaths per year from 2005 to 2021. That number rose to 34 in 2021 and climbed further to 54 in 2022.

City Comptroller Mark Levine estimated that there are “tens of thousands” of homeless New Yorkers, “most of them families with children.”

He said that “nearly 95%” of the city’s homeless population lives in municipal shelters.

In August 2021, those shelters housed 44,586 people, the “lowest daily population in nearly a decade,” according to official data.

However, the shelter population increased from 22,955 to 62,679 people between January 2000 and January 2020, highlighting the long-term growth of homelessness in the city.

NFL Investigating Emails Linking Giants Executive to Jeffrey Epstein

NFL Commissioner Roger Goodell said on Monday that the league will “examine all the facts” regarding contacts between New York Giants co-owner Steve Tisch and Jeffrey Epstein, revealed in documents recently released about the late convicted sex offender.

The batch of files, made public on Friday by the U.S. Department of Justice, includes emails suggesting that Epstein introduced several women to Tisch.

Tisch, a film producer who has never been charged in connection with Epstein, issued a statement last week denying any wrongdoing.

“I had a brief relationship in which we exchanged emails about adult women, and we also discussed film, philanthropy, and investments,” Tisch said of his correspondence with Epstein, which dates back to 2013.

“I did not accept any of his invitations and never went to his island. As we all now know, he was a terrible person and someone I deeply regret having associated with,” he added.

20250501_mh_noexigencia_dui_728x90

Speaking at a press conference in San Jose, California, on Monday, Goodell said the NFL would carefully review the details of the ties between Tisch and Epstein.

“We’re going to examine all the facts,” the commissioner said. “We’re going to look at the context of those exchanges, try to understand them, and see how that fits within the league’s policies.”

Tisch, 76, could face disciplinary action under the NFL’s strict personal conduct policy, even if he is not found guilty of a crime.

“We’re going to take this step by step. First, let’s gather all the facts,” Goodell said at the press conference, which was part of the events leading up to Sunday’s Super Bowl between the Seattle Seahawks and the New England Patriots.
