Kind of reminds me off those macbnors who fled Hong Kong to the UK.
One cannot be dumber then those sorts of libs. But it's also kind of sad, them getting shocked so bad that some even chose to end their lives.

At least those people went by plane. These people are dropped in the middle of a rainforest and have to make the way north by feet!
This is become a routine. LOL
China gained another gem.
A leading expert in the s has joined an institute in the southern Chinese city of Shenzhen, after 33 years in the United States.
Chen Zhoufeng will work as a senior researcher at its Institute of Neurological and Psychiatric Disorders, the Shenzhen Bay Laboratory announced via its official account on Chinese social media platform WeChat.
Chen takes on the full-time faculty position after his decades-old lab at Washington University in St Louis was forced to close over investigations related to the China Initiative – a controversial designed to “counter theft of US secrets and technology”, according to a Chinese news site.
“Professor Chen’s work on the mechanisms of itch is groundbreaking. His team discovered the first ‘itch gene’ and how the sensation is transmitted in neural circuits. The findings settled a long-standing debate in the field, showing that itch and pain are not the same thing,” the Shenzhen Bay Lab said in its post on Sunday.
“His work has inspired research in many related areas, such as skin and anaesthesia, and provided novel drug targets for treating chronic itching, neuro-developmental abnormalities in children, mental health disorders and social autism.”
Chen, a graduate in virology from China’s Wuhan University, had lived in the US since 1990 – first as a doctoral student and then as a researcher and academic.
He earned a PhD in mouse genetics from the University of Texas followed by postdoctoral training at Caltech, before joining the Washington University School of Medicine’s anaesthesiology department as an assistant professor in 2000. He became a full professor in 2009.
Two years later, was appointed founding director of the university’s Centre for the Study of Itch and Sensory Disorders – the world’s first such interdisciplinary study centre.
Chen and his colleagues made a series of discoveries to advance the understanding of how itch works. For instance, they reported that itch was contagious – the brain cells of mice would be activated when they saw other mice scratch, making them start scratching as well.
While the Shenzhen lab announcement did not mention the circumstances of its latest recruitment, Chen’s return is seen as a direct result of his lab at the study centre being shut down and his group dismissed after investigations under the China Initiative.
The policy, launched during the administration of then US president Donald Trump, aimed to curb alleged theft of US intellectual property. But critics said it unfairly targeted Asians, Chinese in particular, with grant fraud cases related to alleged failure to disclose ties to China on their applications.
The fact that most students in Chen’s lab were Chinese nationals might also have gone against him, Wu Xiaobo, an associate professor from the same department as Chen, was quoted as saying by Deep Science.
Chen’s research grants have been suspended, and his lab has been sealed off.
As investigations are not yet complete, it remains unclear if the lab has been closed temporarily or permanently, according to Deep Science.
Although the widely criticised China Initiative was formally closed in February last year, its effects continue to destroy careers, upend lives, and send chilling signals across the academic community.
Earlier this year, China-born molecular biologist Fu Xiangdong resigned from the University of California, San Diego, where he had worked for 30 years. This came after he was investigated and suspended for alleged ties to China.
Shenzhen Bay Lab was opened by the Guangdong provincial government in 2018, with a focus on the prevention, diagnosis, and treatment of cancer, metabolic syndromes, cardiovascular diseases, and neurodegenerative disorders, according to its official website.
The lab has 10 institutes and centres, and around 200 scientists recruited from around the world.
It is headed by Yan Ning, a structural biologist who left Princeton University last November to in the southern Chinese city, the Shenzhen Medical Academy of Research and Translation.
Fu has joined Westlake University in eastern China to continue his world-leading research into Alzheimer’s and Parkinson’s diseases.

It's amazing how much of a force Chinese are in Western scientific fields, seems like they don't get the mainstream admiration or recognition from institutions like Nobel committee proportional to their contribution, Never thought Bamboo ceiling would be applicable in scientific community, it's understandable in corporate businesses it's a dog eat dog environment but this have to say was really unexpected
The Chinese Academy of Sciences has made progress in the study of metasurface micro-hyperspectral imaging
Spectrum is one of the basic properties of matter and is regarded as the fingerprint of matter. Spectral imaging captures the spatial and spectral information of substances by recording the spectra of different spatial positions, which can not only perceive the objective existence of substances, but also understand the components of substances. Spectral imaging technology has been widely used in food safety, biomedicine, environmental monitoring and satellite remote sensing and other fields. A spectral imaging system usually consists of a spectral device (dispersion element or color filter) and a CMOS image sensor. Due to the generally large volume and mass of these spectral devices, the imaging system has a complex structure, a large volume, and a slow imaging speed. This contradicts the requirements of miniaturization, light weight and integration in practical applications.
In order to solve the above problems, Li Hui's team from Suzhou Institute of Biomedical Engineering Technology, Chinese Academy of Sciences and Guo Yinghui's team from Institute of Optoelectronics Technology, Chinese Academy of Sciences cooperated to develop a miniature hyperspectral imaging device based on metasurfaces. The researchers first proposed and verified a computational hyperspectral metasurface design method composed of quasi-random supercells. Quasi-random supercells have strict symmetry, and the polarization sensitivity of spectral devices is low, so spectral devices composed of quasi-random supercells can be better applied in complex working environments. The period of the super unit breaks the limitation of the sub-wavelength scale, the degree of freedom of design is significantly improved, and the types of unit structures are greatly enriched, so that the transmission spectrum corresponding to the selected unit structure meets the requirements of the compressed sensing algorithm, and at the same time reduces the The processing difficulty of the metasurface reduces the cost and cycle of device processing.
That gentleman is the risks and sacrifice democratic country like Canada is more than willing to make for a cause worthy of it's freedom and democracy. This program is written and paid for by AMERICAN MIC. Beauty eh?

Suzhou Nano Institute makes progress in the recyclability and sustainability of fuel cells
A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy, and has the advantages of low environmental pollution and high power generation efficiency. Fuel cells using hydrogen as fuel have no carbon emissions and play an important role in controlling and reducing carbon from the source. In recent years, the industrialization process of fuel cells has developed rapidly. However, research on the recycling of spent fuel cells is at a relatively scarce stage. To fully recover noble metal catalysts and ionomers in fuel cells, membrane electrodes need to be crushed and a solution is used to separate the corresponding materials. In this process, the gas diffusion layer participates in the recycling of membrane electrodes, so that the gas diffusion layer with a slow aging rate in the battery cannot be reused, and a large amount of various types of consumption such as solvents will be generated in the process of recycling noble metals and ionomers.
Zhou Xiaochun's team at the Suzhou Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences prepared a free-standing microporous layer composed of an interpenetrating network of carbon nanotubes. Compared with the traditional microporous layer, this self-contained microporous layer is formed directly without being coated on the macroporous substrate (usually carbon paper) of the gas diffusion layer. The interpenetrating network structure provides the independent microporous layer with excellent physical properties such as high strength, high air permeability, high conductivity and high flatness, so the independent microporous layer exhibits excellent battery performance (peak power up to 1.35 W cm -2 ) and can greatly promote the sustainability of fuel cells. The microporous layer is suitable for carbon paper substrates, and can be applied to various carbon-based and metal-based porous materials (peak power is basically higher than 1 W cm -2 ), providing reliable micropores for highly recyclable substrate layers layer preparation scheme. The microporous layer reduces the combination of the catalytic layer and the gas diffusion layer as well as the microporous layer and the substrate layer, enabling the gas diffusion layer of the fuel cell to be reused after the life of the membrane electrode expires, extending the life of the gas diffusion layer to 138 times (8.2% peak power attenuation). In the recovery process of the membrane electrode assembled with the independent microporous layer, the gas diffusion layer (except the cathode microporous layer) does not need to participate in the recovery of noble metal catalysts and ionomers, so various consumptions in recovery are reduced (more than 90%) ).
