Researchers in Siberia are conducting tests on a juvenile mammoth whose remarkably well-preserved remains were discovered in thawing permafrost after more than 50,000 years.

The creature, resembling a small elephant with a trunk, was recovered from the Batagaika crater, a huge depression more than 80 metres (260 feet) deep which is widening as a result of climate change.

The carcass, weighing more than 110 kg (240 pounds), was brought to the surface on an improvized stretcher, said Maxim Cherpasov, head of the Lazarev Mammoth Museum Laboratory in the city of Yakutsk, according to Reuters.

He said the mammoth was probably a little over a year old when it died, but tests would enable the scientists to confirm this more accurately. The fact that its head and trunk had survived was particularly unusual.

"As a rule, the part that thaws out first, especially the trunk, is often eaten by modern predators or birds. Here, for example, even though the forelimbs have already been eaten, the head is remarkably well preserved," Cherpasov told Reuters.

It is the latest of a series of spectacular discoveries in the Russian permafrost. Last month, scientists in the same vast northeastern region - known as Sakha or Yakutia - showed off the 32,000-year-old remains of a tiny sabre-toothed cat cub, while earlier this year a 44,000-year-old wolf carcass was uncovered.

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.
