Panagis hauls himself out of the pool at a rehabilitation center in Greece and scurries over for a delectable lunch: whole mackerel. It’s been about three months since the orphaned seal pup was found struggling in the coastal waters of Cyprus. Soon, he’ll be well enough to go home.

Panagis is one of dozens of Mediterranean monk seals, or Monachus monachus, that have been nursed back to health by Greece’s MOm, a charity dedicated to the care and protection of the rare marine mammal whose population had dwindled so dramatically that at one point it faced extinction.

Thanks to conservation efforts, the seals with the big, round eyes and prominent whiskers are now making a remarkable comeback. Nearly half of their estimated global population of 800 live in Greek waters, where the extensive coastline offers an abundance of sea caves that provide shelter for females to rear their young.

From near extinction to recovery

Sleek and remarkably fast in the water, the monk seal is a skillful hunter and can consume up to 3 kilograms (6 pounds) of fish, octopus and squid a day. But it's not averse to a ready meal, and can rip through fishing nets to steal fish — which led fishermen to view them as pests.

For decades, they were hunted, contributing to a major population decline between the 1960s and 1980s that led the International Union for Conservation of Nature, or IUCN, to list them as critically endangered.

When conservation efforts began in the 1980s, combined with outreach programs to educate the public — and fishermen — "society gradually began to change ... and the population began to recover," said Panagiotis Dendrinos.

Dendrinos, a marine biologist and coordinator of the Hellenic Society for the Study and Protection of the Monk Seal — or MOm — that has pioneered the Monachus monachus conservation program, says the monk seal is the only seal species in the Mediterranean Sea and also "one of the rarest species of seal and marine mammal in the world."

"To protect an animal like the Mediterranean monk seal in its natural environment, you essentially have to protect the entire marine ecosystem," he said.

Conservation efforts have paid off, and in recent years, the species climbed down a notch on the IUCN’s Red List of threatened species to "endangered." About a year ago improved one step further, to "vulnerable."

A unique seal rehab

Usually contacted by members of the public who find an animal in distress, MOm specialists tend to adult seals on location where possible, and transport young seals to the organization's rehabilitation center housed in the grounds of Athens zoo, on the outskirts of the Greek capital.

There, the young mammals are looked after by veterinarians, fed a special diet to provide them with the best nutrition and hone their swimming skills in a pool.

Their carers give them names — often after the people who found them — but make sure contact with humans is kept to a minimum to prepare the animals for their return into the wild.

The young seals typically stay in the rehab center for several months, until they've put on enough weight and their natural hunting instinct kicks in, allowing them to fend for themselves. They are then tagged so they can be tracked, and re-introduced into the wild.

MOm, the only center of its kind in the region, has cared for about 40 seals from far and wide, both on location and in its facilities, Dendrinos said.

"This year, we had a really pleasant surprise," he said. A female seal that had been treated and released four years ago was spotted nursing a pup.

Planes, boats and cars to the rescue

Panagis was found in Cyprus, near where the body of his mother had been found a few days earlier. Alerted by locals, the organization arranged for the seal to be flown to Athens.

"Transportation is carried out with whatever is available," said veterinary assistant Nikitas Vogiatzis, shortly after feeding Panagis. "Either by plane, or by boat, or even by taxi. "Konstantina came in a taxi, Panagis by plane, Renos came on a boat," he said, listing MOm’s most recent wards.

Weighing just under 15 kilograms (33 pounds) when he arrived, the now 3-month-old seal has reached over 40 kilograms (88 pounds). Panagis is nearly ready for his return trip home, which MOm experts hope will happen in May.

Back into the wild

Renos — short for Renos-Pantelis — was found in November on the small Aegean island of Anafi by a nurse and a military conscript whom he was named after.

The seal pup was shipped to MOm’s facility. He got medical treatment and was put on a special diet until he was old enough to move on to solid fish — the mackerel that Panagis is so fond of.

He recovered and on a cold, sunny February day, it was his turn to head back into the wild. MOm personnel loaded him into a crate and whisked him by speedboat to the uninhabited islet of Gyaros, the closest marine protected area to Athens.

The release location is chosen "based on there being enough food, and there being no disturbance by people, which is very important," said Vogiatzis, the veterinary assistant.

The crate is placed near the water, he said. Then, "you open the door, you say a prayer and you say: ‘So long’."

Renos’ crate was deposited on a beach and the door opened. The young seal sniffed the air timidly, and waited. Slowly, he inched his way out of the crate, then picked up speed as he belly-hauled his way down the beach, splashed into the sea and was gone.

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.
