Sgt. Ian Van Nest rolls slowly through the streets of Churchill, his truck outfitted with a rifle and a barred back seat to hold anyone he has to arrest. His eyes dart back and forth, then settle on a crowd of people standing outside a van. He scans the area for safety and then quietly addresses the group's leader, unsure of the man's weapons.

"How are you today?" Van Nest asks. The leader responds with a wary, "We OK for you here?"

"You’re good. You got a lot of distance there. When you have people disembarking from the vehicle you should have a bear monitor," Van Nest, a conservation officer for the province of Manitoba, cautions as the tourists gaze at a polar bear on the rocks. "So, if that’s you, just have your shotgun with you, right? Slugs and cracker shells if you have or a scare pistol."

It's the beginning of polar bear season in Churchill, a tiny town on a spit of land jutting into Hudson Bay, and keeping tourists safe from hungry and sometimes fierce bears is an essential job for Van Nest and many others. And it's become harder as climate change shrinks the Arctic Sea ice the bears depend on to hunt, forcing them to prowl inland earlier and more often in search of food, according to the International Union for the Conservation of Nature, a group of scientists that tracks how endangered species are.

"You're seeing more bears because there are more bears on the land for longer periods of time to be seen" and they are willing to take more risks, getting closer to people, said Polar Bears International research and policy director Geoff York. There are about 600 polar bears in this Western Hudson Bay population, about half what it was 40 years ago, but that's still close to one bear for every resident of Churchill.

Yet this remote town not only lives with the predator next door, but depends upon and even loves it. Visitors eager to see polar bears saved the town from shrinking out of existence when a military base closed in the 1970s, dropping the population from a few thousand to about 870. A 2011 government study calculated that the average polar bear tourist spends about $5,000 a visit, pumping more than $7 million into a tiny town that boasts fancy restaurants and more than two dozen small places to stay amid dirt roads and no stoplights.

"We’re obviously used to bears so (when you see one) you don’t start to tremble," Mayor Mike Spence said. "It’s their area too. It’s important how the community coexists with bears and wildlife in general to really get along. We’re all connected."

It's been more than a decade since a bear mauled two people in an alley late on Halloween night before a third person scared off the animal.

"It was the scariest thing that's ever happened in my life," said Erin Greene, who along with a 72-year-old man who tried to fight off the bear with a shovel survived their injuries. Greene, who had come to Churchill the year before for a job in the tourist trade, said it was the other animals of Churchill — the beluga whales that she sings to as she runs paddleboat tours and her dozen rescued retired sled dogs — that helped her recover from the trauma.

There have been no attacks since then, but the town is watchful.

At Halloween, trick-or-treating occurs when bears are hungriest, and dozens of volunteers line the streets to keep trouble at bay. Any time of year, troublesome bears that wander into town too often may be put into the polar bear jail — a big Quonset hut-style structure with 28 concrete-and-steel cells — before being returned to the wild. The building doesn't fill up, but it can get busy enough to be noisy from banging and growling inside, Van Nest said.

Residents show polar bear pride in a way that mixes terror and fun, kind of like a rollercoaster.

"You know we're the polar bear capital of the world, right? We have the product, it's just about getting out there to see the bears safely," said Dave Daley, who owns a gift shop, runs dog sleds and talks up the city like the former Chamber of Commerce president he is. "I always tell tourists or whatever ‘You know what, they’re the T. rex like, of the dinosaur era. They're the Lords of the Arctic. They'll eat you."

Usually they don't.

The military base's rocket launch site seemed to keep bears away, and when it closed in the 1970s, they came around more, longtime residents said. So Churchill and province officials "put together a polar bear alert program to make sure the community members were looked after, protected," said Spence, mayor since 1995.

The town's old curfew siren blares nightly at 10 p.m., suggesting to people that it's time to go home for safety from bears. But on this Saturday night, three different bonfire parties are going on at the town beach — a spot next to the school, library and hospital that is a particular hot spot for bears coming inland. Yet no one is leaving.

Then a truck shows up, and a lone figure — one of government's paid guards — gets out, armed with a shotgun. He walks out on the dunes about 100 yards from the parties and scans the horizon for polar bears. The guards are expected to scare any bears away with warning shots, flares, bear spray or noise — not kill them.

"It's just everybody watches out for everybody," Spence said. "So it's just, it's just normal. It kicks into gear as a community that lives alongside polar bears, you're always accustomed to coming out of your house and you look like this and you look ahead. And that's just in your DNA now."

Georgina Berg recalls growing up in the 1970s outside of Churchill, where many First Nations people lived, and how differently her father and mother reacted to a bear sighting. Her father, she said, would see a bear poking in garbage and just walk on by.

"He said, ‘If you don’t bother them, then they won’t bother you’," she recalled.

When a bear came near in later years, after her father had died, her mom was scared.

"Everything was like pandemonium. Everybody was yelling, and all the kids had to come in and everybody had to go home. And then we stayed silent in the house for a long time until we knew for sure that bear was gone, " Berg recalled.

For Van Nest, the provincial officer, the group he came upon that day was plenty safe from a bear about 300 yards (meters) away. He said the bear was "putting on a bit of a show" for the tourists.

"This is a great situation to be in," he said. "The tourists are a safe distance away and the bear’s doing his natural thing and not being harassed by anybody."

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.
