This is unbelievable .. :eek: :eek:

A team of Chinese scientists and surgeons successfully conducted a minimally invasive "brain-spine interface" (BSI) surgery, restoring a paralyzed patient's ability to stand and walk within 24 hours post-surgery. The surgery, fourth of its kind for clinical proof of concept, was conducted at Shanghai's Zhongshan Hospital, but it was the world's first to enable an individual with a total paraplegia – an impairment in motor or sensory function of the lower extremities – to be able to stand and walk through BSI technology, the hospital announced on Tuesday.

The patient, surnamed Lin, is a 34-year-old from south China's Guangdong Province. Two years ago, he fell from a 4-meter-high staircase, sustaining severe spinal injuries and a brain hemorrhage. Despite extensive treatment, Lin's legs remained completely paralyzed, leaving him dependent on a wheelchair. Spinal cord injury disrupts communication between the brain and the part of the spinal cord that controls walking, resulting in paralysis. During the minimally invasive surgery, two electrode chips, each about one millimeter in diameter, were implanted into the brain's motor cortex.

The entire procedure, including both brain and spinal cord interventions, was completed in just four hours. Within 24 hours post-surgery and with the assistance of artificial intelligence, the patient regained leg movement. The most significant challenge of this BSI technology lies in the limited number of electrodes available for implantation in the human body and the ability to decode human movement intentions in real time. From January to February this year, the team had completed three clinical proof-of-concept surgeries. Patients with severe spinal cord injuries regained the ability to control their legs and walk within two weeks. The team will continue to optimize and iterate the technology, aiming to restore walking ability for more spinal injury patients and bring hope to millions of patients and their families worldwide.

China might just have had a final major breakthrough on perovskite solar cells required to commercialize the technology. Scientists from the Eastern China University of Science and Technology found a way to protect perovskite solar cells from aging under sunlight. Their prototype retained 97% efficiency after working non-stop under simulated strong sunlight for 3670 hours or about 153 days, the longest record of perovskite cells so far.

The researchers have already been working with the industry on mass production trials.

Compared to the silicon solar cells, perovskite cells are lighter and thinner, have higher efficiency, and cost less - about one third of the silicon cells.

钙钛矿太阳能电池因其高效、低成本、轻量化等特点,被视为未来光伏技术的重要方向。然而,这类电池存在一个关键问题——稳定性较差,难以长期使用。3月7日,华东理工大学的一项研究成功破解了这一难题,相关成果已发表在国际顶级期刊《科学》(Science)。据悉,科研团队成功找到延长钙钛矿太阳能电池寿命的关键方法,这项“命短”难题的破解,让人类距离用上更便宜、更轻薄的太阳能板又近了一大步。

钙钛矿太阳能电池被称作“未来之光”,它不仅能像传统硅电池一样发电,还能做成薄如纸张、可弯曲的形态,甚至能贴在衣服或窗户上使用。但多年来,这种电池有个致命弱点:在阳光下用不了多久就会“衰老”,使用寿命远达不到实际应用要求。

研究团队揭开了这个“短命”谜团。研究发现,钙钛矿材料在阳光照射下会像气球一样反复膨胀收缩,时间一长就会“内伤”破裂。这种材料遇光会膨胀超过1%,内部晶体相互挤压产生破坏力,就像反复折叠的纸最终会断裂一样。

科研人员想出了一个妙招——给材料穿“防弹衣”。他们用世界上最坚硬的材料之一石墨烯,加上特殊透明塑料,制成只有头发丝万分之一的超薄保护层。实验证明,这层“防护服”能让材料抗压能力翻倍,把膨胀幅度从0.31%降到0.08%,就像给易碎品加了抗震包装。

经过严格测试,装上这种保护层的太阳能电池创下新纪录:在模拟日常使用的强光高温环境下,持续工作3670小时(约153天)后,仍能保持97%的发电效率。这是目前同类电池中最长的稳定工作时间,意味着实际应用成为可能。

这项突破不仅给出解决方案,更颠覆了科学界认知。过去十年,全球科学家主要从材料配方改良入手,而华东理工团队首次发现“物理损伤”这个隐藏杀手,为后续研究打开新方向。相关专家表示,这项工作重新定义了提升稳定性的技术路径。

研究团队透露,该技术已开始与企业合作试验。一旦量产,将带来革命性变化:建筑外墙的发电玻璃、可折叠的户外充电毯甚至给手机充电的太阳膜都可能成为现实。据估算,钙钛矿电池生产成本仅为硅电池的1/3,发电效率还有提升空间。

随着稳定性瓶颈的突破,这项“实验室里的未来科技”正加速走向千家万户,为全球绿色能源转型提供“中国方案”。

Seem even foreign doctors r more aware of it than those local professionals...
Yeah, it's a promising drug, and the interviews on the street are just stupid. I'm a doctor in the US and I can't name a single American biotech startup, why would you expect people on the street to be able to? Heck, if I wasn't interested in stocks I wouldn't even be able to tell you who makes Ozempic.

Also, if I understand correctly the Beijing hospital thing was people not trusting cheaper generics that the government insurance covers. That's not an uniquely Chinese issue, I see that all the time here in the US as well. I've met plenty of patients who demand name brand drugs and refuse to take the generics that insurance companies cover, making me write justifications to the insurance companies to have them cover the name brand drugs. There's actually some reasoning behind this. There are in fact some differences in manufacturing and by law (at least in the US) some degree of variation in the amount of active ingredients is allowed. So while on a population basis generics work just about as well as name brands, on an individual basis some people just respond better to certain manufacturer's meds than others.

China will set up a $140 billion national venture capital fund for high-tech industries such as "AI, quantum computing, hydrogen energy, bio-manufacturing, 6G, etc".

A mRNA cancer vaccine, which is designed by a Chinese biopharmaceutical company based on each patient's gene mutation (gene mutation that may lead to the development of cancer later) with the assistance of AI, has entered clinical trial.
EVM16 is a novel personalized therapeutic mRNA cancer vaccine that contains neoantigens with high immunogenicity potential, predicted based on the unique tumor mutations of each patient using Everest’s proprietary AI-based neoantigen prediction algorithm EVER-NEO-1, Everest explained. It uses a lipid nanoparticle delivery system to deliver neoantigen-encoded mRNA in vivo, activating neoantigen-specific tumor-killing T cells and inhibiting tumor growth.
