When they first started climbing the Andes peaks, they could hear the ice crunching under their crampons. These days, it’s the sound of melted water running beneath their feet that they mostly listen to as they make their ascents.

Dressed in colorful, multilayered skirts, a group of 20 Indigenous Bolivian women — known as the Cholita climbers — have been climbing the mountain range for the past eight years, working as tourist guides. But as the glaciers in the South American country retreat as a result of climate change, they worry about the future of their jobs.

The Aymara women remember a time when practically every spot on the glaciers was covered in snow, but now there are parts with nothing but rocks.

"There used to be a white blanket and now there is only rock," said Lidia Huayllas, one of the climbers. "The thaw is very noticeable."

Huayllas said she has seen the snow-capped Huayna Potosí mountain, a 6,000-meter (19,600-feet) peak near the Bolivian city of El Alto, shrink little by little in the past two decades.

"We used to walk normally; now, there are rocks and water overflowing," said the 57-year-old woman as she jumped from stone to stone to avoid getting her skirt and feet wet.

Edson Ramírez, a glaciologist from the Pierre and Marie Curie University in France, estimates that in the last 30 years, Bolivian glaciers have lost 40% of their thickness due to climate change. In the lower parts of the mountain, he says, the ice has basically vanished.

"We already lost Chacaltaya," said Ramírez, referring to a 5,400-meter (17,700-feet) mountain that used to be a popular ski resort and now has no ice left.

With no ice left in the lower parts of the mountain range, the Cholita climbers need to go further up to find it. This has reduced the number of tourists seeking their services as guides.

Huayllas would not say how much she makes as a tour guide, but she said a Cholita climber currently makes about $30 per tour. That is less than the $50 per tour they used to make.

In 2022, during the September-December climbing season, the Cholitas did 30 tours, Huayllas said. This year, through early November, they had barely done 16.

The situation has gotten so critical, the 20 women have looked for other jobs to make ends meet. Some of the Cholitas have started making and selling blankets and coats with alpaca wool from the Andes, Huayllas said.

"If this continues, we're going to have to work in commerce or do something else for a living," said Huayllas, although she quickly dismissed her own pessimistic thought, somehow hoping for a change: "No. This is our source of work."

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.

Thai police donned a lion dance costume during this week's Lunar New Year festivities to arrest a suspect accused of stealing about $64,000 worth of Buddhist artifacts, police said Thursday.

Officers dressed as a red-and-yellow lion made the arrest on Wednesday evening after receiving a report earlier this month of a home burglary in the suburbs of the capital, Bangkok, AFP reported.

Capital police said the reported break-in involved "numerous Buddhist objects and two 12-inch Buddha statues", along with evidence of repeated attempts to enter the house, according to a statement.

With few leads, police kept watch for weeks before hatching an unusual plan to join a lion dance procession at a nearby Buddhist temple.

"Officers gradually moved closer to the suspect before arresting him," police said.

A video released by police showed the festive lion dancers approaching the suspect before an officer suddenly emerged from the head of the costume and, with help from colleagues, pinned him to the ground.

Police estimated the value of the stolen items at around two million baht ($64,000).

The suspect, a 33-year-old man, has a criminal record involving drug offences and theft, police added.
