Secret that helps some trees live more than 1,000 years

Scientists have found that some trees like “ginkgo trees” can live for more than 1,000 years.

Researchers in the US and China studied growth rings taken from inside the trunks of 34 healthy ginkgo trees. The trees ranged in age from 15 to 667 years old. They found that the ginkgos didn’t stop growing as they aged, although the rings grew thinner.

They found that, no matter what their age, the trees produced protective chemicals that helped defend against outside stressors such as disease or drought.

“In humans, as we age, our immune system begins to start to not be so good,” said Richard Dixon, a biologist at the University of North Texas. But in a way, “the immune system in these trees, even though they’re 1,000 years old, looks like that of a 20-year-old.”

“As ginkgo trees age, they show no evidence of weakening their ability to defend themselves from stresses,” Dixon added.

The study concluded that, in effect, old ginkgo trees stay healthy by preventing aging and maintaining their ability to resist external stresses.

Ginkgo trees are native to China and are known for their distinctive fan-shaped leaves that turn buttery yellow in the fall. Besides their longevity, fossils of the species date back to the time of the dinosaurs.

They’re listed as endangered in the wild but, the Maidenhair tree, like the ginkgo, is also known, is found in many parks and gardens across the world.
 
Some Ginkgos are thought to be as old as 3,000 years, but that doesn’t make them the world’s oldest tree. Bristlecone pine with approximately 5,000 years-age is the oldest tree in the world.

Red Cross official seeks ‘staggered’ return of Afghan refugees from Pakistan

A senior Red Cross official has called for the return of Afghan refugees from Pakistan to occur “in a more staggered way” so Afghanistan can better absorb them.

“It will be important to work with the government of Pakistan in 2024 to ask that if there are going to be returnees,” that they arrive “in smaller numbers at a time just so it is more manageable on the Afghan side,” said Alexander Matheou, regional director, Asia Pacific Region for the International Federation of the Red Cross, Voice of America (VOA) reported on Saturday.

Speaking in the Qatari capital, Doha, Matheou told journalists on Friday the challenges facing Afghan returnees from Pakistan was one of several pressing issues he discussed with the officials of the Islamic Emirate in Kabul.

“You will be aware that over half a million have crossed the border over recent months, and it is likely that we will see large numbers of new arrivals in the coming months,” he said.

“I imagine this is probably the largest population flow in a short period of time in Asia since the population movement from Myanmar into Bangladesh in 2017,” he added. “So, it is a significant event.”

Since October, Pakistan has expelled more than 500,000 Afghan refugees who lacked proper documentation.

Matheou noted many of the returnees have lived in Pakistan for decades and are ill-equipped to begin a new life in a country that to them is unknown, without government or international support.

He described the returnees as being in generally poor health, especially the children, who account for nearly half of all returnees.

“The evidence of that was we visited clinics where they reported a real spike in cases of acute malnutrition coming from the arrivals from Pakistan.

“We visited routine immunization programs of the IFRC and the Afghan Red Crescent in the villages, and there it was clear looking at the children that as well as being anemic, you could see wasting and stunting among the children,” he said.
