On behalf of 80 countries, China calls for high-quality AI development to assist children’s mental health at UNHRC

Chinese ambassador Chen Xu called for the high-quality development of artificial intelligence (AI), assistance in promoting children’s mental health, and protection of children’s rights while delivering a joint statement on behalf of 80 countries at the 55th session of the United Nations Human Rights Council (UNHRC) on Thursday.

Chen, China’s permanent representative to the UN Office in Geneva and other international organizations in Switzerland, said that artificial intelligence is a new field of human development and should adhere to the concept of consultation, joint construction, and shared benefits, while working together to promote the governance of artificial intelligence.

The new generation of children has become one of the main groups using and benefiting from AI technology. The joint statement emphasized the importance of children’s mental health issues.

APOE from patient-derived astrocytic extracellular vesicles alleviates neuromyelitis optica spectrum disorder in a mouse model

Analyzing cells from patients with neuromyelitis optica spectrum disorder, researchers show transfers of patient-derived extracellular vesicles rich in the apolipoprotein APOE alleviate neuroinflammation and slow astrocyte loss in a mouse model of this severe autoimmune disease.

📄 :

APOE was augmented in astrocytic extracellular vesicles from patients with neuromyelitis optica spectrum disorder and decreased brain lesions in a mouse model.

Paralyzed man walks again using only his thoughts

“For 12 years I’ve been trying to get back my feet. Now I have learned how to walk normal, natural.”

A paralyzed man is walking again thanks to a “digital bridge” researchers created between his brain and a spinal stimulator.

“For 12 years I’ve been trying to get back my feet,” the 40-year-old Dutch man, Gert-Jan Oskam, told reporters on May 23. “Now I have learned how to walk normal, natural.”

The patient: Oskam was living in China in 2011 when he sustained a spinal cord injury that left his legs paralyzed. About five years later, he had a spinal stimulator implanted below the site of his injury as part of a clinical trial in Switzerland.

Neurological conditions now leading cause of ill health and disability globally, new analysis finds

Globally, the number of people living with, or dying from, neurological conditions such as stroke, Alzheimer’s disease and other dementias, and meningitis has risen substantially over the past 30 years due to the growth and aging of the global population as well as increased exposure to environmental, metabolic, and lifestyle risk factors. In 2021, 3.4 billion people experienced a nervous system condition, according to a major new analysis from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021, published in The Lancet Neurology.

The analysis suggests that worldwide, the overall amount of disability, illness, and —a measurement known as disability-adjusted life years (DALYs)—caused by neurological conditions increased by 18% over the past 31 years, rising from around 375 million years of healthy life lost in 1990 to 443 million years in 2021.

The absolute number of DALYs is increasing in large part due to aging and growing populations worldwide.

‘Universal’ brain wave pattern discovered across primate species — including humans

Scientists have discovered a universal pattern of brain waves in multiple primate species, including humans.

This pattern of electrical activity is seen in the six layers of tissue that cover the outside of mammals’ brains, known as the cerebral cortex. In primates, higher frequency waves of electrical activity dance through the most superficial layers while slower waves bubble in layers below.
