    AI Blood Test Predicts Diseases 15 Years Early

    Key Takeaways

    1. A new AI-powered blood test can predict disease risks up to 15 years in advance.
    2. The “Human Health and Disease Proteome Map” was created by analyzing blood samples from over 50,000 individuals over 14 years.
    3. Researchers focused on nearly 3,000 plasma proteins to forecast hundreds of diseases, including Alzheimer’s and heart disease.
    4. The test aims to be affordable, costing about $5-10, making it accessible for regular health assessments, especially for older individuals.
    5. AI is also enhancing drug discovery, potentially reducing research time from 15-20 years to just 3-5 years.

    A revolutionary blood test powered by AI might be able to predict the chances of certain diseases as much as 15 years before any signs show up.

    New Discoveries in Blood Testing

    Scientists from China have introduced the first-ever “Human Health and Disease Proteome Map” after analyzing blood samples from over 50,000 individuals over a span of 14 years. This new technique utilizes artificial intelligence to identify early indicators in plasma, which could lead to diagnosing conditions like Alzheimer’s and heart disease much earlier than before.

    Research Developments

    Researchers from Fudan University started by investigating nearly 1,500 plasma proteins and focused on 11 that could indicate a future risk of dementia. By widening their study to examine almost 3,000 proteins in human blood and using AI methods, their system can now forecast the risk of hundreds of diseases well over a decade in advance.

    “The main benefit of this technology is its capability for early detection at a lower cost,” mentioned Yu Jintai, who is the deputy director of the Fudan University Research Institute and also serves as the Deputy Director of Neurology at Huashan Hospital. The team is currently developing a quick test kit that aims to make this type of screening as easy and affordable as checking blood pressure or blood sugar levels.

    Future Implications and Cost

    When this test becomes available, it may only cost a few dozen yuan (approximately $5-10). This pricing makes it particularly beneficial for middle-aged and older individuals who require regular health assessments.

    This advancement is part of a broader trend in AI-enhanced healthcare in China. For instance, Shen Ning and his team at Liangzhu Laboratory in Hangzhou have used AI algorithms to create a new treatment for children suffering from progeria, and the initial findings seem promising.

    According to Shen, AI can significantly speed up the drug discovery process, reducing research time from the usual 15-20 years to just 3-5 years—while also boosting the chances of successful outcomes.

  • Chinese Researchers Develop New Method to Extend Lithium-Ion Battery Life Sixfold

    Chinese Researchers Develop New Method to Extend Lithium-Ion Battery Life Sixfold

    Key Takeaways

    1. New method can extend lithium-ion battery lifespan by over six times.
    2. Discovery of trifluoromethyl sulfonate lithium as an effective lithium carrier.
    3. Treated batteries can maintain performance for 12,000 charging cycles with minimal decline.
    4. Implementation requires battery design for electrolyte replenishment and gas venting.
    5. Environmental benefits include reduced electronic waste and lower reliance on lithium extraction.

    A new method for repairing batteries developed by researchers from China has the potential to extend the lifespan of lithium-ion batteries by more than six times. This innovation could significantly change how durable electric vehicles and mobile devices are. The research, published in the journal Nature, focuses on injecting a special solution that revives aged batteries to levels close to their original performance.

    Discovery of a New Lithium Carrier

    Over a span of four years, experts in macromolecular science at Fudan University—Gao Yue and Peng Huisheng—identified a new lithium carrier named trifluoromethyl sulfonate lithium. This molecule is effective in replenishing lost lithium ions in older batteries and works well with various battery types and electrolytes.

    Impressive Laboratory Results

    The lab tests yielded remarkable results: a commercial lithium iron phosphate battery, after being treated, could keep its original performance for 12,000 charging cycles. This is a stark increase from the typical lifespan of 2,000 cycles. Even more striking, the treated battery exhibited only a four percent decline in performance after 11,818 cycles. In comparison, a regular electric vehicle battery usually experiences a 30 percent capacity reduction within roughly 2.7 years of similar charging patterns.

    Requirements for Implementation

    For this technology to be effective, batteries must be designed with components that allow for the replenishment of electrolytes and the safe venting of gases. In the rejuvenation process, the compound breaks down to release lithium ions, which subsequently reconnect with the electrode material, while also producing gaseous byproducts that need to be properly vented.

    Environmental Benefits

    This advancement could significantly benefit the environment, as it not only prolongs battery life but also reduces electronic waste and reliance on lithium extraction. Fudan University states that the solution is cost-effective and ready for scaling. The research team is currently collaborating with leading global battery manufacturers to accelerate the process of commercialization.

    Conclusion

    In conclusion, this innovation marks a major transition from conventional battery designs, leading to more sustainable battery technologies in the industry. However, additional testing and regulatory approvals are essential before this groundbreaking solution can be widely adopted.
