A soothing cup of rice? Chinese scientists create grain with health benefits of tea
Chinese scientists have engineered the first 'tea rice' enriched with the antioxidant compounds that make green tea a health-boosting drink. Advertisement The rice has been fortified with the micronutrient catechin, and the researchers behind it say it can provide the health benefits of tea without any side effects from caffeine. 'Catechins, as key antioxidant components in tea plants with high content, offer certain benefits to human health,' the team said in a paper published in the peer-reviewed Plant Biotechnology Journal in March. 01:33 2-metre 'giant rice' twice as tall as other varieties nearly ready for first harvest in China 2-metre 'giant rice' twice as tall as other varieties nearly ready for first harvest in China Catechin flavonoids are a type of polyphenol – micronutrients that occur naturally in plants – shown to have antibacterial, anti-inflammatory, anticancer and cardioprotective properties. Catechins are thought to play a role in regulating blood pressure, aiding in weight loss, and lowering the risk of cardiovascular disease. 'These essential flavonoid phytonutrients are renowned for their pivotal role in bestowing the unique health benefits associated with tea plant consumption,' the team said. Advertisement Catechins make up around 15 to 30 per cent of the dry weight of tea, with particularly high levels found in green tea as it does not undergo the same oxidation process that black tea does during processing. While green tea contains these beneficial compounds, it also contains caffeine, which can cause people to experience symptoms like insomnia and heart palpitations, particularly when consumed in large amounts.

'We Can Read Your Secrets From a Mile Away': China Unleashes Laser Tech That Detects Sesame-Sized Text With Brutal Precision
IN A NUTSHELL 🔬 Chinese scientists have developed a cutting-edge laser-based system capable of reading tiny text from nearly a mile away. capable of reading tiny text from nearly a mile away. 🌌 This innovation relies on active intensity interferometry to reconstruct detailed images by analyzing light behavior. to reconstruct detailed images by analyzing light behavior. 🏛️ Potential applications include archaeology, environmental monitoring, and security, with significant implications for various fields. 🚀 Ongoing research aims to enhance the technology with better laser control and AI-driven algorithms for improved accuracy. Imagine standing on one side of a vast valley, effortlessly reading the label on a bottle perched on the opposite hill. No binoculars, telescopes, or cameras are needed. This is not a scene from a futuristic spy movie but a reality made possible by a groundbreaking innovation from Chinese scientists. They have developed a laser-based system capable of clearly discerning tiny details, such as text the size of a sesame seed, from nearly a mile away. This technological marvel has the potential to revolutionize various fields, from archaeology to environmental research, by enabling detailed observations from great distances. The Science of Long-Distance Reading Until recently, the ability to read fine details from afar was fraught with difficulties. Traditional telescopes and high-powered lenses often suffer from distortion caused by the atmosphere, which blurs and scatters light over long distances. This limitation makes it challenging to distinguish small features like printed text. However, the new laser-based approach overcomes these obstacles by analyzing how light behaves when it reflects off surfaces, rather than focusing solely on the image itself. This method, known as active intensity interferometry, allows researchers to achieve remarkable clarity. The process involves directing eight infrared laser beams at a distant target. The reflected light is then collected by two separate telescopes, strategically placed apart. Instead of merely capturing an image, these telescopes track subtle shifts in light intensity over time. Advanced computer algorithms then process these patterns to reconstruct the intricate details of the target surface, including text as small as three millimeters. In contrast, a standard telescope system would only discern shapes approximately 1.65 inches in size at the same distance.

The researchers acknowledge that while active intensity interferometry shows significant potential for high-resolution optical imaging and sensing, several limitations must be addressed to fully realize its capabilities. One major hurdle is the precise alignment required between the lasers and telescopes, which can be cumbersome in certain applications. Additionally, the system necessitates a clear line of sight and illumination of the target with lasers, making it less suitable for scenarios requiring stealth. Nevertheless, the research team is actively working to enhance the system. Future improvements aim to refine laser control and incorporate AI-powered algorithms to achieve even greater image accuracy. These ongoing efforts suggest that the technology will continue to evolve, opening up new possibilities in various fields.
