A crowd has gathered to see off Rose, a loggerhead sea turtle, who labors across the Tunisian sand to rejoin the waters of the Mediterranean.

For the last month, Rose has been recovering at the First Aid Sea Turtle Center in the coastal city of Sfax after she was ensnared in a fishing net.

The facility, one of two in North Africa, is run by the EU-funded Life Med Turtles project, which looks after endangered species, such as the loggerhead, and aims to improve marine life protection by gathering data on their behavior.

Since the center opened in 2021, nearly 80 turtles have been treated and returned to their natural environment, said its chief Imed Jribi.

The project also aims to educate the local population in places like Sfax, which relies on fishing.

"Before, we were ignorant," said 29-year-old local fisherman Hamadi Dahech, who brought Rose into the center after trapping her accidentally.

"People ate them, used them for witchcraft, or as medicine and many other things. Today, thanks to (the center) raising awareness among fishermen, she has a better chance of survival at sea," Dahech said at Rose's release.

Do not eat

"We use the turtles that arrive here for scientific research, for their protection as well as raising awareness," Jribi said.

To highlight the natural wonders in the waters off Tunisia, the center opens to the general public on weekends.

Malak Morali, a 30-year-old local who brought her two children to watch Rose's release, said her son loves the ocean-going creatures.

"Every time he hears that there are turtles, he wants to come to take photos and learn new things," she said.

Morali said that it was only thanks to the center that she learnt "that the meat is not edible".

"We usually say that cooking it is good, but it is the opposite."

The consumption of sea turtle meat is dangerous due to the high levels of pollution in the waters they inhabit.

Toxins, such as mercury, build up in their liver and kidneys, posing a significant threat to human health.

Besides the deadly metals, the turtles often eat floating waste.

The creatures can "confuse plastic bags with jellyfish", said Hamed Mallat, a marine biologist.

A 2015 study by the University of Queensland in Australia found that the majority of the world's sea turtle population was consuming plastic.

Trapped in nets

Every year, around 10,000 loggerheads are caught by trawlers and in fishing nets in the waters off Tunisia, a potential death sentence for the turtles.

Life Med Turtles estimates that around 70 percent of sea turtle deaths in the Mediterranean alone are caused by gillnets, a sort of large net suspended vertically in the water.

Some, however, make it through alive and at the center in Sfax, it is often the fishermen themselves who bring in the injured turtles.

As an acknowledgement of their help, the rescued animals are frequently named after the fishermen themselves.

One of them, a frail baby turtle called Ayoub, was fed by caretakers with a syringe.

As well as fishing, global warming poses an acute threat to the turtles by altering their sex ratio.

According to the US National Ocean Service, if a turtle's egg incubates below 27.7 Celsius (81.9 degrees Fahrenheit), the hatchling will be male.

But above 31 degrees Celsius the baby turtle will be female, putting the turtles at greater risk of extinction as fewer males are born.

The rescue center in Sfax nonetheless has hope and is continuing its work to prevent the death of the species.

Before releasing Rose, Jribi and Mallat attached a location tracker to her shell.

They aim to analyze where Rose is most active, which could reveal more about her species' migration and behavior.

"She is the one who will protect the ecosystem at sea," said Rose's rescuer Dahech.

South Korean researchers have developed a lightweight wearable robot that can walk up to paraplegic users and lock itself onto them, enabling them to walk, manoeuvre obstacles and climb staircases.

The Exoskeleton Laboratory team at the Korea Advanced Institute of Science and Technology (KAIST) said their goal is to create a robot that seamlessly integrates into the daily lives of individuals with disabilities.

Kim Seung-hwan, who is himself a paraplegic and part of the KAIST team, demonstrated the prototype which helped him walk at a speed of 3.2 kph (2 mph), climb a flight of stairs and take sideways steps to slide into a bench.

"It can approach me wherever I am, even when I’m sitting in a wheelchair, and be worn to help me stand up, which is one of its most distinct features," Reuters quoted Kim.

The powered exoskeleton, named WalkON Suit F1, features aluminium and titanium composition to weigh in at 50 kg (110 lb), and is powered by 12 electronic motors that simulate the movements of human joints while walking.

Park Jeong-su, another member of the KAIST team, said he was inspired by the movie "Iron Man". "After watching Iron Man, I thought it would be great if I can help people with a robot in real life."

To ensure the user's balance while walking, the robot is equipped with sensors on its soles and in the upper body that monitor 1,000 signals per second and anticipate the user's intended movements.

Lenses on the front of the robot work as eyes which analyse its surroundings, identify the height of stairs and detect obstacles to compensate for the lack of sensory ability of users with complete paraplegia, Park said.

Kim Seung-hwan won the gold medal while wearing the WalkON Suit F1 in the exoskeleton category at Cybathlon 2024, opens new tab, which saw developers with varying physical disabilities demonstrate assistive robots in eight categories.

"I wanted to tell my son .... that I also used to able to walk. I wanted to share a diverse range of experiences with him," said Kim.
