More than 500,000 children in Afghanistan are at risk of malnutrition in 2025, the United Nations warned on Wednesday.

In a statement, the UN said one of the reasons for the alarming situation is climate extremes, which "have limited people's ability to feed their families."

According to a recent report by the UN Office for the Coordination of Humanitarian Affairs (OCHA), nearly half of Afghanistan's population – about 22.9 million people – will require humanitarian aid this year to address both chronic and acute needs.

Afghanistan's fragile economy, ongoing natural disasters and climate-induced shocks, along with regional political instability, continue to impede recovery from decades of conflict, the report noted.

Since the Islamist Taliban's return to power in August 2021, Afghanistan does not have access to its foreign reserves in Western banks, further exacerbating the country's economic crisis.

Unemployment and poverty affect around 48% of the population, according to the UN.

The country remains highly vulnerable to climate-related disasters.

More severe flooding is anticipated in 2025, which like in previous years, is expected to destroy homes, agricultural land and displace communities, further worsening the already dire humanitarian situation.

Members of Donald Trump's presidential transition team are laying the groundwork for the United States to withdraw from the World Health Organization on the first day of his second term, according to a health law expert familiar with the discussions.

"I have it on good authority that he plans to withdraw, probably on Day One or very early in his administration," said Lawrence Gostin, professor of global health at Georgetown University in Washington and director of the WHO Collaborating Center on National and Global Health Law, Reuters reported.

The Financial Times was first to report on the plans, citing two experts. The second expert, former White House COVID-19 response coordinator Ashish Jha, was not immediately available for comment.

The Trump transition team did not immediately respond to a Reuters request for comment.

The plan, which aligns with Trump's longstanding criticism of the U.N. health agency, would mark a dramatic shift in U.S. global health policy and further isolate Washington from international efforts to battle pandemics.

Trump has nominated several critics of the organization to top public health positions, including Robert F. Kennedy Jr., a vaccine skeptic who is up for the post of secretary of Health and Human Services, which oversees all major U.S. health agencies including the CDC and FDA, read the report.

Trump initiated the year-long withdrawal process from the WHO in 2020 but six months later his successor, President Joe Biden, reversed the decision.

Trump has argued that the agency failed to hold China accountable for the early spread of COVID-19. He has repeatedly called the WHO a puppet of Beijing and vowed to redirect U.S. contributions to domestic health initiatives.

A WHO spokesperson declined to directly comment but referred Reuters to comments by WHO Director-General Tedros Adhanom Ghebreyesus at a press briefing on Dec. 10 in which he was asked whether he was concerned that the Trump administration would withdraw from the organization.

Tedros said at the time that the WHO needed to give the U.S. time and space for the transition. He also voiced confidence that states could finalize a pandemic agreement by May 2025.

Critics warn that a U.S. withdrawal could undermine global disease surveillance and emergency response systems, Reuters reported.

"The U.S. would lose influence and clout in global health and China would fill the vacuum. I can't imagine a world without a robust WHO. But U.S. withdrawal would severely weaken the agency," Gostin said.

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, Reuters reported.

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," Kim said.

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, read the report.

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, which saw developers with varying physical disabilities demonstrate assistive robots in eight categories, Reuters reported.

"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.
