Chinese scientists create visual sensor that adapts to extreme light changes in seconds
The bionic
visual sensor can adapt to extreme changes between dark and light in about 40 seconds, compared to two to 30 minutes for human eyes.
Its ability to adjust sensitivity for better object recognition and imaging means the sensor could be used to make next-generation
technology , such as more brain-like
computing systems
'The sensor with visual adaptive function proposed in this work has great potential for future applications in artificial intelligence sensing fields such as autonomous driving and bionic
robotics ,' the team said in a paper published in the American Institute of Physics' peer-reviewed journal Applied Physics Letters on July 1.
The novel vision system is also able to overcome issues with current systems to provide faster computation with less energy use, the research team from Fuzhou University said.
The human visual system – the retina, optic nerve, and the brain's visual cortex – can adapt to extreme changes in light and memorise these settings to adapt faster the next time it encounters similar conditions.

Meet some of the Chinese AI scientists dominating the field's global top 100
A study of nearly 200,000 researchers and 100,000 high-impact papers has revealed that the vast majority of the world's top 100 brains in the field of artificial intelligence are of Chinese origin. The list was compiled by ITPO China – part of the UN Industrial Development Organisation (UNIDO) – and the Shenzhen-based technology firm Dongbi Data . It was presented last week at a conference in Beijing. Jun-Yan Zhu is an assistant professor at Carnegie Mellon University's school of computer science and one of the world's leading artificial intelligence experts.

Another 20 of the world's AI experts work at institutes in the US. Notably, half of those are of Chinese descent, including Jun-Yan Zhu, an assistant professor at Carnegie Mellon University's school of computer science – making a total of 65 out of 100. The analysis covered more than 96,000 high-level papers from leading publications such as the Journal of Machine Learning Research and IEEE Transactions on Pattern Analysis and Machine Intelligence, as well as top conferences in the sector, from 2015 to 2024. The research team assessed the impact of each AI scientist by counting and analysing the number of papers and citations produced over the term of the study.

Chinese scientists create visual sensor that adapts to light changes in seconds

‘Too good to refuse': why world's top flying insect detective Jason Chapman chose China
As a world expert on insect migration, Jason Chapman knows a thing or two about the impact of travel. The top British ecologist has now made his own move, a career decision that has underscored the growing prominence of China in the fields of natural science. Chapman's decision to leave the UK for a full-time position at a Chinese university reflects the country's expanding global influence in research. This includes a cutting-edge radar that can track flying insects, technology that the acclaimed behavioural ecologist could not resist. Substantial financial support and a commitment to agricultural research have helped China to develop world-class entomological radar technology, Chapman said. 'China is now certainly the world leader in radar entomology, with many people working in this field,' said Chapman, who worked at the University of Exeter before moving to Nanjing Agricultural University (NJAU) in June. Chapman's research focuses on the evolution of insect migration strategies and the impact of long-range movements. When he joined Rothamsted Research in the United Kingdom as a postdoctoral fellow in 1999, his lab was one of the few teams worldwide pioneering the application and research of entomological radar.
