Lucia Ortíz trudges through endless fields of cempasuchil flowers, the luminescent orange petals of which will soon cloak everything from city streets to cemeteries across Mexico.

Here, in the winding canals and farms on the fringes of Mexico City, the flower also known as the Mexican marigold has been farmed for generations, and takes the spotlight every year in the country's Day of the Dead celebrations.

But as 50-year-old Ortíz and other farmers busily bundle clusters of the plant to sell in markets around the capital, they quietly wonder what will be left of their livelihood down the line, The AP news reported.

That’s because cempasuchil growers say they’ve been left reeling by torrential rains, stretching drought and other impacts from climate change — caused by the burning of fuels like gas, oil and coal — that have grown increasingly common.

Farmers, who depend on the ebbs and flows of the weather to cultivate their crops, are on the front line on the climate crisis. This year alone, cempasuchil producers said they lost up to half their flower crop from heavy rains and flooding.

“This year, we lost a lot. We struggled to even grow the cempasuchil. There were moments in which we didn’t have the money to buy fertilizer we needed,” Ortíz said. “With the cempasuchil plants, we’ve sometimes been left with nothing.”

‘Flower of the dead’ The orange flower has become a symbol of the country’s celebrations that take place every Nov. 1 and 2. Also known as the “flower of the dead”, the cempasuchil is believed to be a point of connection between the worlds of the dead and the living, with bright petals that light the path of dead souls to the altars set out by their family.

The flowers are also a crucial economic engine across Mexico, which commerce groups predict will rake in nearly 2.7 million dollars for farmers in 2025.

Ortíz and her family began growing the flower 30 years ago in their small plot of land in Xochimilco, a rural borough in the south of Mexico City where residents have continued to carry on ancient farming techniques using canals that wind through farmlands like a maze.

Every year, locals begin to plant the marigold seeds in July, and grow the plants as the rainy season winds down. But they say that they’ve been dealt a heavy blow for consecutive years as heavy rains, drought, floods and other climate shifts have made it increasingly difficult to keep their crops alive.

This year, torrential rains stretching on for months wiped out more than 37,000 acres of crops across the country, according to government figures. In a visit to cempasuchil fields earlier this month in Xochimilco, Mexico City Mayor Clara Brugada said that as many of 2 million marigold plants were put at risk. Despite that, she said that production this year simultaneously broke a record of 6 million plants as farmers ramp up to meet increasing demand even as growing the flower has become more precarious.

Ortíz said the excess of rain has brought on pests, diseases and rotted the roots of her plants. She estimates she lost at least 30% of her crop, while others say they’ve lost closer to 50%.

The family has been forced to drop money on insecticides, fertilizer and more to save their crops. As they have, razor thin profit margins have turned into losses, and they’ve had to cut back on basics like beef and sweets to make ends meet.

“If I were to take a hard look at all our losses, I’d be incredibly disillusioned and even not want to grow them anymore,” she said. “We’re just trying to push forward and make sure this keeps going on.”

Adapting to climate change Just down the road from Ortíz’s farm, government scientists are searching for long-term solutions beyond the short-term economic relief provided by the local government. In a small seed bank known as Toxinachcal, men in white suits meticulously pick through sprouts in a lab dish.

The scientists have been at work for a year and a half saving up thousands of seed variants of native plant species, including 20 variants of cempasuchil, in jars lining giant freezers in the hopes that the storage facility will be a key tool in fighting the most adverse effects of climate change.

Biologist Clara Soto Cortés, head of the seed bank, said part of the reason that the crop has been devastated is because farmers in recent years have elected to use a hybrid marigold seed variant from the United States.

The seed produces a shorter, more uniform-looking plant that is easier to sell en-masse and in places like supermarkets.

But that means farmers have turned away from sturdier, native breeds, which have longer stocks and widely vary in color, size and texture. The genetic diversity of these Mexican breeds makes them more resilient to drastic climate shifts like the ones seen this year, Soto said.

“These native seeds have adapted to different geographies, in high altitudes and low, in places where there's a lot of rain or there's none at all, or where they need to be resistant to insects,” she said.

“The (hybrid) seeds have been bred for another purpose. It doesn't have the genetic diversity needed to take on climate change.”

If more climate events, like the floods that roiled producers wipe out an entire crop, Soto said the bank will make seeds available to local producers to recover their crops – this time with a more resilient variant that their ancestors have been farming for centuries.

Carrying on an ancient tradition Meanwhile, growers are scrambling to bounce back in the short term, saying the losses also represent a threat to the farming tradition their families have struggled to maintain on the edge of the dense city of 23 million people.

Carlos Jiménez, 61, has long worked the fields of Xochimilco, but began to grow the shorter marigold plants eight years ago when he noticed the hybrid was more marketable. As he's lost more crops and gotten lower prices for the plants because of the mildew gathering at their roots, he said he's begun considering ways to adapt, like building greenhouses.

“The plants get sick, they rot, and our business is snuffed out,” Jiménez said. “And with it goes our tradition because it's our economy."

Producers like Ortíz have considered the same. But their losses mean they have no money to build added infrastructure. Her family and other farmers have called on local authorities for help, but say they've received just pennies on the dollar of what they need to bounce back. Though the local government has said it continues to work to help offset the blow felt by farmers.

She said she's begun to look at other crops she might be able to farm that are more resilient than the crinkled orange flowers.

Others like Jiménez said that while the roots of plants may rot around him, for now he's holding strong.

“This plant has a deeper meaning to our lost loved ones,” he said. “These are traditions we carry down from our ancestors. They can't just disappear.”

Freezing rain led to flights being suspended at Vienna airport on Tuesday, while neighboring Slovakia, Czech Republic and Hungary also experienced travel disruptions.

Snow and freezing temperatures buffeted Europe last week, with gale-force winds and storms claiming some 15 lives, causing travel mayhem, shutting schools, and cutting power to hundreds of thousands.

A thick layer of ice on the Vienna airport runways led to arriving flights being diverted to other airports, while all departing flights were put on hold early Tuesday.

Austria's state railway company OeBB also asked travelers to postpone non-urgent journeys, with numerous train connections facing interruptions and cancellations.

In neighboring Slovakia, the Bratislava airport was also closed early Tuesday due to bad weather.

Slovak police on Facebook urged people to avoid travel because of "extreme" ice and snow in the west of the country.

In the Czech Republic, ice was also hampering road and rail traffic.

Prague airport came to a virtual standstill, with firefighters having to de-ice the runways.

Around 50 people were treated for injuries because of the icy conditions, according to Prague's emergency services, cited by the CTK agency.

In Hungary, meteorological services also issued alerts for freezing rain and snowfall as severe winter conditions affect a large part of the country.

Trains and flights were experiencing delays, while authorities reported drift ice on the Danube and the Tisza rivers, where icebreakers have been put on alert.

Lake Balaton in the west of the country is currently frozen -- a relatively rare phenomenon seen about once every ten to fifteen years.

However, authorities warned that the ice is still too thin for skating, urging the public to be cautious.

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.
