From Cyprus to New Zealand, Lebanon and beyond, environmentalists worry about the proliferation of quarries in a world ever greedier for concrete. Concrete consumption has tripled over the past 20 year.

Over 40 billion tons a year of sand and gravel are extracted around the world from mountains, rivers, coastlines and marine environments, the majority for construction. With the global population expected to grow by two billion by 2050, demand can only go up, according to the UN environment agency. The extraction process often comes with deforestation, air pollution and disruption of traditional human activities.

This is the case in Cyprus, near the hut where Jamal makes traditional "hellim" cheese, trucks come to collect rock, kicking up clouds of dust and frightening the animals.

On the quarried area of the mountain slope, vegetation has disappeared. A policeman asks the goat herder to stay back as an explosion triggers a huge cloud of smoke and part of the rock face collapses. On another mountain, Jamal was injured and lost animals to quarrying work.

Rocks "rained down on us," he recalled.

While he understands the "need for rock to build", he hopes the company running the site will help him find quieter pastures in the Turkish Republic of Northern Cyprus established in 1974, and on which live 355,000 people. This region walks the line between development and conservation.

Cenk Sarper, head of the Stone Quarries Union, said: "Today, the island is fed by tourism so we need hotels, guest houses, roads and airports. We don't have any other choice than to exploit the quarries."

He said the quarries operate in areas far from residential zones and respect all the adopted environmental standards. More than 12,000 tons of rock is extracted every day, or around 33 kilograms per capita. The world average is 18 kilograms, according to the UN.

Asking to remain anonymous, a contractor said that key actors "did not do everything possible to limit visual pollution." Some accuse companies from Turkey of being less vigilant than Turkish Cypriot ones.

The secretary general of the biologists' association in northern Cyprus, Hasan Sarpten, regrets that a large quarry was authorized far from a reserved area, in the west.

"They are not applying the best methods" environmentally, he said, criticizing the lack of regulation by Turkish Cypriot authorities.

These authorities declined to comment when contacted by AFP.

Environmentalists are equally worried in the internationally recognized Republic of Cyprus.

Environment expert Klitos Papastylianou said: "The growing extraction of raw materials for the construction industry is one of the main threats for protected areas."

Green Party MP Charalampos Theopemptou noted that "marinas and coast protection works require huge amounts of rocks."

An audit recommended increasing fines to discourage illegal quarrying. Calls for stricter controls resound around the world. In Lebanon, where illegal quarries have cleared entire mountains and hundreds of thousands of trees, activists are pushing back, despite death threats.

Beyond smart watches and rings, artificial intelligence is being used to make self-testing for major diseases more readily available -- from headsets that detect early signs of Alzheimer's to an iris-scanning app that helps spot cancer.

"The reason preventive medicine doesn't work right now is because you don't want to go to the doctor all the time to get things tested," says Ramses Alcaide, co-founder and CEO of startup Neurable.

"But what about if you knew when you needed to go to the doctor?"

Connected rings, bracelets and watches -- which were everywhere at last week's Consumer Electronics Show in Las Vegas -- can already monitor heart rate, blood pressure and glucose levels, with varying degrees of accuracy.

These gadgets are in high demand from consumers. A recent study published by OpenAI showed that more than 200 million internet users check ChatGPT every week for information on health topics.

On Wednesday, OpenAI even launched a chatbot that can draw on a user's medical records and other data collected by wearable devices, with their consent, to inform its responses.

Using electroencephalogram (EEG) technology, Neurable has developed a headset that records and deciphers brain activity.

The linked app compares data with the user's medical history to check for any deviation, a possible sign of a problem, said Alcaide.

"Apple Watch can pick up Parkinson's, but it can only pick it up once you have a tremor," Alcaide said. "Your brain has been fighting that Parkinson's for over 10 years."

With EEG technology, "you can pick these things up before you actually see physical symptoms of them. And this is just one example."

Detection before symptoms

Some people have reservations about the capabilities of such devices.

"I don't think that wearable EEG devices are reliable enough," said Anna Wexler, a University of Pennsylvania professor who studies consumer detection products, although she acknowledges that "AI has expanded the possibilities of these devices."

While Neurable's product cannot provide an actual diagnosis, it does offer a warning. It can also detect signs of depression and early development of Alzheimer's disease.

Neurable is working with the Ukrainian military to evaluate the mental health of soldiers on the front lines of the war with Russia, as well as former prisoners of war, in order to detect post-traumatic stress disorder (PTSD).

French startup NAOX meanwhile has developed EEG earbuds linked to a small box that can help patients with epilepsy.

Rather than detect seizures, which are "very rare," the device recognizes "spikes" -- quick, abnormal electrical shocks in the brain that are "much more difficult to see," said NAOX's chief of innovation Marc Vaillaud, a doctor by training.

NAOX's device -- which has been cleared by the US Food and Drug Administration -- is designed to be worn at night, to track several hours of data at a time.

The company is working with the Rothschild and Lariboisiere hospitals in Paris to try to better understand the links between these brain "spikes" and Alzheimer's disease, which have been raised in scientific papers.

Advances in AI and technology in general have paved the way for the miniaturization of cheaper detection devices -- a far cry from the heavy machinery once seen in medical offices and hospitals.

IriHealth is preparing to launch, for only about $50, a small smartphone extension that would scan a user's iris.

The gadget relies on iridology, a technique by which iris colors and markings are believed to reveal information about a person's health, but which is generally considered scientifically unreliable.

But the founders of IriHealth -- a spin-off of biometrics specialist IriTech -- are convinced that their device can be effective in detecting anomalies in the colon, and potentially the lungs or the liver.

Company spokesman Tommy Phan said IriHealth had found its device to be 81 percent accurate among patients who already have been diagnosed with colon cancer.

Hawaii's Kilauea was spraying a spectacular fountain of lava on Monday, keeping up its reputation as one of the world's most active volcanoes.

For over a year now, Kilauea has been regularly throwing out thousands of tons of molten rock and gases since it burst to life in December 2024, reported AFP.

Volcanologists with the US Geological Survey said the incandescent lava was being hurled more than 1,500 feet (460 meters) into the air, with plumes of smoke and gases rising as high as 20,000 feet (six kilometers).

Eruptions such as this one tend to last around one day, the USGS said, but can still vent up to 100,000 tons of sulfur dioxide.

This gas reacts in the atmosphere to create a visible haze known as vog -- volcanic smog -- which can cause respiratory and other problems.

Tiny slivers of volcanic glass, known as "Pele's hair," are also being thrown into the air.

Named after Pele, the Hawaiian goddess of volcanoes, the strands can be very sharp and can cause irritation to the skin and eyes.

The eruption poses no immediate danger to any human settlement, with the caldera having been closed to the public for almost two decades.

Kilauea has been very active since 1983 and erupts relatively regularly.

It is one of six active volcanoes located in the Hawaiian Islands, which also include Mauna Loa, the largest volcano in the world.

Kilauea is much smaller than neighboring Mauna Loa, but it is far more active and regularly wows helicopter-riding tourists who come to see its red-hot shows.

NASA announced that four astronauts will return from the International Space Station more than a month ahead of schedule after an unnamed crew member experienced a medical issue.

The incident marks the first time in history NASA has brought astronauts home from the space station early because of a medical issue, according to CNN.

NASA has not provided details about the nature of the problem, citing privacy concerns. The agency typically does not discuss the specifics of health matters related to astronauts.

A SpaceX Crew Dragon capsule will bring the four-person crew home, disembarking from the ISS as soon as Wednesday at 5 pm ET. The spacecraft is then expected to splash down off the coast of California early the following morning, NASA said in a statement last week.

The affected astronaut is in stable condition, NASA previously confirmed, and is not expected to receive special treatment during the return trip, said Dr James Polk, NASA’s chief health and medical officer at the agency’s headquarters.

The astronaut would also be best served by being evaluated on the ground, Polk added.

“We have a very robust suite of medical hardware on board the International Space Station,” Polk noted during a news conference. “But we don’t have the complete amount of hardware that I would have in the emergency department, for example, to complete a workup of a patient.”

He added, “And in this particular incident, we would like to complete that work up, and the best way to complete that workup is on the ground.”
