    Fudan University Helps Blind Mice Gain Predator-Like Vision

    Key Takeaways

    1. Researchers from Fudan University developed a nanowire retinal implant that enables mice to perceive both visible and infrared light, potentially restoring vision for those with retinal damage.

    2. The implant uses tellurium nanowires (TeNWN) to replace damaged light-sensing cells, converting light into electrical signals for the brain.

    3. Blind mice with the implant could respond to visible and infrared light and distinguish between shapes, indicating improved visual processing.

    4. The implants showed biocompatibility and stability for up to 60 days, but long-term effects and detail resolution limitations remain to be studied.

    5. This research follows previous work where Fudan researchers restored walking ability in paralyzed patients using brain-spine interfaces.

    Researchers from Fudan University in Shanghai, China, have successfully enabled ‘three blind mice’ to perceive both visible and infrared light through a nanowire retinal implant. This groundbreaking discovery could lead to the restoration of vision for countless individuals who have lost their sight due to retinal damage.

    Understanding the Retina

    The retina is a crucial layer of light-sensitive tissue located at the back of the eye, responsible for transforming visible light energy into electrical signals that the brain can interpret. Blindness may arise from various issues, like macular degeneration or retinal detachment, when the light-sensing components of the retina are irreparably harmed. To help slow down the progression of age-related macular degeneration (AMD), AREDS2 supplements are available on Amazon.

    The Role of the Nanowire Implant

    The Fudan retinal implant substitutes damaged organic light-sensing cells with a tellurium nanowire (TeNWN) neuroprosthesis, which can turn visible and near-infrared light (up to 2000 nm) into electrical signals for the brain. Humans typically cannot see infrared light, and using this spectrum presents a different view of the world.

    After the implantation of the TeNWNs, the blind mice were examined and found to respond to intense visible and infrared light sources as well as distinguish between shapes, such as circles and triangles. Their vision resembled that of the Predator (you might want to rewatch this classic Schwarzenegger movie on Amazon). The tellurium nanowires’ arrangement, combined with the material’s high optical absorption and narrow bandgap, allows for efficient conversion of photons to electrons without the need for an external power supply.

    Limitations and Future Trials

    The implants have a moderate ability to resolve details, meaning that sight restoration isn’t flawless. Additionally, while the implants appeared biocompatible and stable for up to 60 days post-implantation, long-term studies are still pending.

    Previously, the Fudan researchers showed that they could restore walking ability within 24 hours to patients completely paralyzed from the waist down via their minimally invasive, triple-integrated brain-spine interfaces (BSIs).

  • AI Blood Test Predicts Diseases 15 Years Early

    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.

    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.
