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.

Child Found Malnourished in Van in France; Father Admits Confinement

French gendarmes discovered a child in a van in Hagenbach, in northeastern France, after a neighbor reported hearing what she described as “childlike noises” coming from the parked vehicle.

After unlocking the van, officers found the boy lying in a fetal position, unclothed and covered with a blanket, surrounded by garbage and near human waste, according to a statement from the Mulhouse prosecutor, Nicolas Heitz.

Authorities said the child appeared pale and severely malnourished. Due to prolonged confinement in a seated position, he was no longer able to walk. He was immediately taken to a hospital in Mulhouse for medical care.

The boy’s father, who lived with his partner and two daughters aged 10 and 12, admitted to keeping the child confined and depriving him of proper care.

According to the prosecutor, the man said he placed the child in the van in November 2024, claiming he wanted to “protect him” because his partner intended to have the boy admitted to a psychiatric facility.

The suspect also stated that he allowed the child out of the vehicle in May 2025 and permitted him to enter the family apartment around mid-year, when the rest of the family was on vacation.

The man’s partner—who is not the child’s mother—also faces charges, including failure to report abuse. However, she has denied all accusations.

Europe Faces Jet Fuel Shortage Risk Amid Hormuz Disruption

The Airports Council International Europe has warned of a potential “systemic shortage” of jet fuel if maritime traffic through the Strait of Hormuz is not restored within the next three weeks, according to a letter reviewed by AFP on Friday.

In the document, addressed to the European Commission and first reported by the Financial Times, the European airport lobby stated that a “systemic jet fuel shortage will become a reality” in the European Union unless stable and significant transit through the strait resumes soon.

The association, which represents around 600 airports across 50 countries, called on Brussels to implement “urgent monitoring of fuel availability and supply” over the next six months.

Jet fuel prices have surged amid the conflict in the Middle East and the ongoing disruption in the Strait of Hormuz, a critical chokepoint for global energy transport.

The conflict escalated on February 28 following joint U.S. and Israeli airstrikes against Iran.

In response, Tehran imposed several countermeasures, including blocking maritime traffic through the strait, a route through which roughly 20% of the world’s oil, jet fuel, and gas supply passes.

Artemis II crew prepares for Earth return and splashdown recovery

Astronauts from the Artemis II mission are expected to be extracted from the Orion spacecraft approximately two hours after splashdown, scheduled for 20:07 UTC this Friday (6:07 p.m. in San Salvador), according to NASA.

Following recovery, a rescue team will transport the crew by aircraft to the USS John P. Murtha. Once onboard, they will undergo medical evaluations before boarding another flight to the Johnson Space Center.

On Thursday, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian astronaut Jeremy Hansen from the Canadian Space Agency, continued preparations for their return to Earth.

Their activities include stowing equipment used during the mission, securing cargo and storage compartments, and installing and adjusting crew seats to ensure all items are properly fastened. The crew will also review the latest weather updates, recovery operations status, and reentry timeline, while preparing for post-landing procedures.

At 21:53 UTC (9:53 p.m. in San Salvador), Orion’s thrusters are scheduled to perform a second trajectory correction maneuver, refining the spacecraft’s path back to Earth. During this operation, Hansen will monitor guidance, navigation, and propulsion systems.

NASA explained that during Friday’s reentry, the service module will separate about 20 minutes before Orion reaches the upper atmosphere southeast of Hawaii. If necessary, a final trajectory adjustment will fine-tune the flight path before the capsule begins a series of roll maneuvers to safely distance itself from jettisoned components.

Just before atmospheric interface, Orion will reach a peak speed of approximately 3,800 km/h. As it descends to about 400,000 feet (around 121.9 km), communications will be interrupted for approximately six minutes due to plasma formation around the capsule during peak heating.

NASA expects the crew to experience up to 3.9 G during a nominal reentry profile. After exiting the blackout phase, the capsule will jettison its forward bay cover. Drogue parachutes will deploy at around 22,000 feet (6.7 km), followed by the three main parachutes at approximately 6,000 feet (1.8 km).

Artemis II marks NASA’s first crewed flight test of the Space Launch System (SLS) rocket and Orion spacecraft around the Moon. The mission aims to validate capabilities for deep space human exploration and lay the groundwork for future long-term scientific missions on the lunar surface.
