Cruel heat is baking southern Europe as the continent slips deeper into summer.

In homes and offices, air conditioning is sweet relief. But under the scorching sun, outdoor labor can be grueling, brutal, occasionally even deadly.

A street sweeper died in Barcelona during a heatwave last month and, according to a labor union, 12 other city cleaners have suffered heatstroke since. Some of Europe's powerful unions are pushing for tougher regulations to protect the aging workforce from climate change on the world's fastest-warming continent.

Cleaning the hot streets

Hundreds of street cleaners and concerned citizens marched through downtown Barcelona last week to protest the death of Montse Aguilar, a 51-year-old street cleaner who worked even as the city's temperatures hit a June record.

Fellow street sweeper Antonia Rodríguez said at the protest that blistering summers have made her work “unbearable.”

“I have been doing this job for 23 years and each year the heat is worse,” said Rodríguez, 56. “Something has to be done.”

Extreme heat has fueled more than 1,000 excess deaths in Spain so far in June and July, according to the Carlos III Health Institute.

“Climate change is, above all, playing a role in extreme weather events like the heatwaves we are experiencing, and is having a big impact in our country,” said Diana Gómez, who heads the institute’s daily mortality observatory.

Even before the march, Barcelona’s City Hall issued new rules requiring the four companies contracted to clean its streets to give workers uniforms made of breathable material, a hat and sun cream. When temperatures reach 34 C (93 F), street cleaners now must have hourly water breaks and routes that allow time in the shade. Cleaning work will be suspended when temperatures hit 40 C (104 F).

Protesters said none of the clothing changes have been put into effect and workers are punished for allegedly slacking in the heat. They said supervisors would sanction workers when they took breaks or slowed down.

Workers marched behind a banner reading “Extreme Heat Is Also Workplace Violence!" and demanded better summer clothing and more breaks during the sweltering summers. They complained that they have to buy their own water.

FCC Medio Ambiente, the company that employed the deceased worker, declined to comment on the protesters' complaints. In a previous statement, it offered its condolences to Aguilar's family and said that it trains its staff to work in hot weather.

Emergency measures and a Greek cook

In Greece, regulations for outdoor labor such as construction work and food delivery includes mandatory breaks. Employers are also advised, but not mandated, to adjust shifts to keep workers out of the midday sun.

Greece requires heat-safety inspections during hotter months but the country's largest labor union, the GSEE, is calling for year-round monitoring.

European labor unions and the United Nations’ International Labor Organization are also pushing for a more coordinated international approach to handling the impact of rising temperatures on workers.

"Heat stress is an invisible killer,” the ILO said in a report last year on how heat hurts workers.

It called for countries to increase worker heat protections, saying Europe and Central Asia have experienced the largest spike in excessive worker heat exposure this century.

In Athens, grill cook Thomas Siamandas shaves meat from a spit in the threshold of the famed Bairaktaris Restaurant. He is out of the sun, but the 38 C (100.4 F) temperature recorded on July 16 was even tougher to endure while standing in front of souvlaki burners.

Grill cooks step into air-conditioned rooms when possible and always keep water within reach. Working with a fan pointed at his feet, the 32-year-old said staying cool means knowing when to take a break, before the heat overwhelms you.

“It’s tough, but we take precautions: We sit down when we can, take frequent breaks and stay hydrated. We drink plenty of water — really a lot,” said Siamandas, who has worked at the restaurant for eight years. “You have to find a way to adjust to the conditions.”

The blazing sun in Rome

Massimo De Filippis spends hours in the blazing sun each day sharing the history of vestal virgins, dueling gladiators and powerful emperors as tourists shuffle through Rome’s Colosseum and Forum.

“Honestly, it is tough. I am not going to lie,” the 45-year-old De Filippis said as he wiped sweat from his face. “Many times it is actually dangerous to go into the Roman Forum between noon and 3:30 p.m.”

At midday on July 22, he led his group down the Forum’s Via Sacra, the central road in ancient Rome. They paused at a fountain to rinse their faces and fill their bottles.

Dehydrated tourists often pass out here in the summer heat, said Francesca Duimich, who represents 300 Roman tour guides in Italy’s national federation, Federagit.

“The Forum is a pit; There is no shade, there is no wind,” Duimich said. “Being there at 1 p.m. or 2 p.m. in the summer heat means you will feel unwell.”

This year, guides have bombarded her with complaints about the heat. In recent weeks, Federagit requested that the state’s Colosseum Archaeological Park, which oversees the Forum, open an hour earlier so tours can get a jump-start before the heat becomes punishing. The request has been to no avail, so far.

The park’s press office said that administrators are working to move the opening up by 30 minutes and will soon schedule visits after sunset.

When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacular fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing towards their instruments.

The German team managed to measure the pollution the rocket's upper stage emitted in our planet's difficult-to-study upper atmosphere -- the first time this has been achieved, according to a study published on Thursday.

It is vital to learn more about this little-understood form of pollution because of the huge number of satellites that are planned to be launched in the coming years, the scientists emphasized.

In the early hours of February 19, 2025, the upper stage of a Falcon 9 rocket was tumbling back to Earth when it exploded into a fireball that made headlines from the UK to Poland.

"We were excited to try and test our equipment and hopefully measure the debris trail," the team led by Robin Wing and Gerd Baumgarten of the Leibniz Institute of Atmospheric Physics in Germany told AFP via email.

In particular, the scientists wanted to measure how the rocket polluted what they call the "ignorosphere" -- because it is so difficult to study.

This region between 50 to 100 kilometers (31 to 62 miles) above Earth includes the mesosphere and part of the lower thermosphere.

- 'Harbinger' -

The team used technology called LIDAR, which measures pollution in the atmosphere by shooting out lots of laser pulses and seeing which bounce back off something.

They detected a sudden spike in the metal lithium in an area nearly 100 kilometers above Earth. This plume had 10 times more lithium than is normal in this part of the atmosphere.

The team then traced the plume back to where the rocket re-entered the atmosphere, west of Ireland.

For the first time, this proves it is possible to study pollution from re-entering rockets at such heights before it disperses, the scientists said.

But the impact from this rocket pollution remains unknown.

"What we do know is that one ton of emissions at 75 kilometers (altitude) is equivalent to 100,000 tons at the surface," they said.

The study warned the case was a "harbinger" of the pollution to come, given how many rockets will be needed to launch all the satellites that Earth is planning to blast into space.

Currently, there are around 14,000 active satellites orbiting our planet.
In the middle of last month, China applied for permission to launch around 200,000 satellites into orbit.

Then at the end of January, billionaire Elon Musk's SpaceX applied for permission to launch one million more.

Eloise Marais, a professor of atmospheric chemistry at University College London not involved in the new study, told AFP the research was "really important".

"There is currently no suitable regulation targeting pollution input into the upper layers of the atmosphere," she explained.

"Even though these portions of the atmosphere are far from us, they have potentially consequential impacts to life on Earth if the pollutants produced are able to affect Earth's climate and deplete ozone in the layer protecting us from harmful UV radiation."

The study was published in the journal Communications Earth & Environment.

For more than a century, biology textbooks have stated that vision among vertebrates - people included - is built from two clearly defined cell types: rods for processing dim light and cones for bright light and color. New research involving deep-sea fish shows this tidy division is, in reality, not so tidy.

Scientists have identified a new type of visual cell in deep-sea fish that blends the shape and form of rods with the molecular machinery and genes of cones. This hybrid type of cell, adapted for sight in gloomy light conditions, was found in larvae of three deep-sea fish species in the Red Sea, Reuters reported.

The species studied were: a hatchetfish, with the scientific name Maurolicus mucronatus; a lightfish, named Vinciguerria mabahiss; and a lanternfish, named Benthosema pterotum. The hatchetfish retained the hybrid cells throughout its life. The other two shifted to the usual rod-cone dichotomy in adulthood.

All three are small, with adults measuring roughly 1-3 inches (3-7 cm) long and the larvae much littler. They inhabit a marine realm of twilight conditions, with sunlight struggling to penetrate into the watery depths.

The vertebrate retina, a sensory membrane at the back of the eye that detects light and converts it into signals to the brain, possesses two main types of light-sensitive visual cells, called photoreceptors. They are named for their shape: rods and cones.

"The rods and cones slowly change position inside the retina when moving between dim and bright conditions, which is why our eyes take time to adjust when we flick on the light switch on our way to the restroom at night," said Lily Fogg, a postdoctoral researcher in marine biology at the University of Helsinki in Finland and lead author of the research published in the journal Science Advances.

"We found that, as larvae, these deep-sea fish mostly use a mix-and-match type of hybrid photoreceptor. These cells look like rods - long, cylindrical and optimized to catch as many light particles - photons - as possible. But they use the molecular machinery of cones, switching on genes usually found only in cones," Fogg said.

The researchers examined the retinas of fish larvae caught at depths from 65 to 650 feet (20 to 200 meters). In the type of dim environment they inhabit, rod and cone cells both are usually engaged in the vertebrate retina, but neither works very well. These fish display an evolutionary remedy.

"Our results challenge the longstanding idea that rods and cones are two fixed, clearly separated cell types. Instead, we show that photoreceptors can blend structural and molecular features in unexpected ways. This suggests that vertebrate visual systems are more flexible and evolutionarily adaptable than previously thought," Fogg said.

"It is a very cool finding that shows that biology does not fit neatly into boxes," said study senior author Fabio Cortesi, a marine biologist and neuroscientist at the University of Queensland in Australia. "I wouldn't be surprised if we find these cells are much more common across all vertebrates, including terrestrial species."

All three species emit bioluminescence using small light-emitting organs on their bodies, mostly located on the belly. They produce blue-green light that blends with the faint background light from the sun above. This strategy, called counterillumination, is a common form of camouflage in the deep sea to avoid predators.

"Small fish like these fuel the open ocean. They are plentiful and serve as food for many larger predatory fishes, including tuna and marlin, marine mammals such as dolphins and whales, and marine birds," Cortesi said.

These kinds of fish also engage in one of the biggest daily migrations in the animal kingdom. They swim near the surface at night to feed in plankton-rich waters, then return to the depths - 650 to 3,280 feet (200 to 1,000 meters) - during daytime to avoid predation.

"The deep sea remains a frontier for human exploration, a mystery box with the potential for significant discoveries," Cortesi said. "We should look after this habitat with the utmost care to make sure future generations can continue to marvel at its wonders."

Osaka has received an unusual donation -- 21 kilograms of gold -- to pay for the maintenance of its ageing water system, the Japanese commercial hub announced Thursday.

The donation worth $3.6 million was made in November by a person who a month earlier had already given $3,300 in cash for the municipal waterworks, Osaka Mayor Hideyuki Yokoyama told a press conference.

"It's an absolutely staggering amount," said Yokoyama, adding that he was lost for words to express his gratitude.

"I was shocked."

The donor wished to remain anonymous, AFP quoted the mayor as saying.

Work to replace water pipes in Osaka, a city of 2.8 million residents, has hit a snag as the actual cost exceeded the planned budget, according to local media.
