They’ve shown a part of the body known to recycle proteins has a secret mode that can spew out an arsenal of bacteria-killing chemicals.

The researchers in Israel say it transforms our understanding of how we are protected against infection.

And gives a new place to look for antibiotics to tackle the growing problem of superbugs that resist our current drugs.

The discovery centres on the proteasome – a tiny structure that is found in every cell of the body.

Its main role is to chop up old proteins into smaller chunks so they can be recycled to make new ones.

But a series of experiments, detailed in the journal Nature, shows the proteasome detects when a cell has been infected by bacteria.

It then changes structure and role. It starts transforming old proteins into weapons that can rip open the outer layer of bacteria to kill them.

Prof Yifat Merbl, from the Weizmann Institute of Science, told me: “This is really exciting, because we never knew that this was happening.

“We discovered a novel mechanism of immunity that is allowing us to have a defence against bacterial infection.

“It’s happening throughout our body in all the cells, and generates a whole new class of potential natural antibiotics.”

The research team went through a process they called “dumpster diving” to find these natural antibiotics.

They were tested on bacteria growing in the laboratory and on mice with pneumonia and sepsis. The researchers said they were getting results comparable to some established antibiotics.

And when the researchers took cells in the laboratory and disabled the proteasome they were far easier to infect with bacteria like Salmonella.

Prof Daniel Davis, the head of life sciences and an immunologist at Imperial College London, said the findings were “extremely provocative and very interesting” as they changed our understanding of how our body fights infection.

“What’s really exciting about this, is it’s a totally undiscovered process by which anti-germ molecules are made inside our cells, it feels profoundly important and surprising.”

But he cautioned that turning this into a new source of antibiotics is an idea that “still needs to be tested” and that will take time.

More than a million people a year are estimated to die from infections that are resistant to drugs like antibiotics.

But despite the need, there has been a lack of research into developing new antibiotics to keep up with demand.

Against that bleak background, having somewhere new to look is a source of optimism for some scientists.

Dr Lindsey Edwards, a senior lecturer in microbiology at King’s College London, told the BBC: “It’s a potential goldmine for new antibiotics, that’s quite exciting.

“In previous years it’s been digging up soil [to find new antibiotics], it is wild that it’s something we have within us, but comes down to having the technology to be able to detect these things.”

She also says there could be fewer issues with developing them into drugs because they are already products of the human body so the “safety side of it might be a lot easier”.

He remains in good spirits and deeply appreciates the excellent care he is receiving,” Angel Ureña wrote on X, formerly Twitter.

He said Clinton was admitted to Georgetown University Medical Center in Washington, DC on Monday evening for tests and observation after developing the fever.

Mr Ureña’s statement did not give more details on the Arkansas Democrat’s condition, though US media reports indicate Clinton is expected to recover.

A source close to Clinton told NBC News that the situation is “not urgent” and the former president would be “fine.”

The news network reported Clinton was awake and alert.

This is the latest health scare for the 42nd US president, who served in the White House from 1993 to 2001.

Clinton, 78, was last admitted to the hospital for six days in 2021 in California after developing an infection in his blood. He is also known to have suffered with heart issues in the past.

In 2004, aged 58, he had a quadruple bypass surgery after doctors found signs of extensive heart disease and, ten years later, he had a clogged artery opened after complaining of chest pains.

Not long after his second surgery, the ex-president – known for his love of fatty foods – went vegan. He told Politico in 2016, “I might not be around if I hadn’t become a vegan. It’s great.”

Clinton was active on the presidential campaign trail this year, as he travelled the country to boost Vice-President Kamala Harris’s bid for president.

Last month, he released his latest book, Citizen: My Life After the White House.

Dozens of indigenous Teduray people reported symptoms such as diarrhoea, vomiting and abdominal spasms since eating the dish last week in a seaside town in Maguindanao del Norte Province, officials said.

While it is illegal to hunt or consume sea turtles under the Philippines’ environmental protection laws, the marine creatures are still eaten as a traditional delicacy in some communities.

But sea turtles that consume contaminated algae – including those that appear healthy – can be toxic when cooked and eaten.

Some of the dogs, cats and chickens that were fed the same sea turtle also died, Irene Dillo, a local official said. She added that authorities were investigating the cause of the deaths.

The sea turtle was cooked as adobo, a popular Filipino dish consisting of meat and vegetables stewed in vinegar and soy sauce.

Residents of Datu Blah Sinsuat, a coastal town known for its white, sandy beaches and clear waters, frequently get their food from the sea. “It was unfortunate because there is so much other seafood in their village – lobsters, fish,” Ms Dillo said.

Most of the residents who were hospitalised have since been discharged, local media reported, while the three who died were buried immediately – in line with local tradition.

Datu Mohamad Sinsuat Jr, a local councillor, said that he has told local officials to strictly enforce the ban on hunting sea turtles in the region, vowing “this food poisoning incident will never happen again”.

Most sea turtle species are classified as endangered, and it is illegal in the Philippines to collect, harm or kill any of them. However sea turtles are hunted in some cultures for their flesh and eggs, which are believed to contain medicinal properties.

In 2013, 68 people in Philippines’ Eastern Samar Province fell ill – and four of them died – after consuming a sea turtle found near their village.
