China's scientists use tellurium to restore vision in mice, let monkeys see infrared
Chinese researchers have reportedly made a breakthrough in artificial vision technology using a rare mineral called tellurium. This development could one day help restore sight to the blind, perhaps even enhancing it beyond natural capabilities. The breakthrough was made by researchers at Fudan University in Shanghai, who developed an artificial retina implant composed of tellurium nanowires. These wires, the team reports, were then implanted into blind mice who miraculously regained their vision. The scientists also tested the new technology on a blind monkey, which likewise showed a marked improvement in vision. The team also implanted the nanowires into a sighted monkey which, it is claimed, gained the ability to see infrared light. This is very interesting as this electromagnetic wavelength is ordinarily invisible to mammals. So why did the researchers select tellurium, you might ask? Well, tellurium is a rare element with excellent photoelectric properties. This means it can readily capture light, including infrared radiation. The mineral can also be used to convert infrared light into electrical signals without needing other equipment. This mimics how photoreceptor cells in a healthy retina work, i.e., they convert light into signals your brain interprets as images. The team created tiny nanowires of tellurium just 150 nanometres thick, or a thousand times thinner than a human hair. These were grown into a mesh-like network called tellurium nanowire networks (TeNWNs). This network forms a 'nano-scaffold', which was implanted onto the retinas of blind animals. Once implanted into test subjects, the animals showed much restored pupillary responses. Their visual cortex (the brain's vision center) also showed a marked response to light, and they could locate and respond to visible and infrared light sources. During tests, the formerly blind mice performed nearly as well as sighted mice in pattern recognition tasks. According to the team, the test mice with the tellurium nano-scaffold could detect and locate infrared LEDs that normal mice couldn't see. In monkeys, the device showed no adverse effects, and in sighted monkeys, it enhanced infrared vision. China also happens to control the lion's share of its production, giving it strategic mineral is currently used in various applications, including solar panels, semiconductors, thermoelectric devices, and, most recently, neural vision implants. As for whether this technology could be tested on humans, it is unlikely to happen in the short term as approval for human testing needs to be obtained first. However, a similar technology unveiled in 2023, using the inorganic compound titanium dioxide, is already undergoing clinical trials. That said, the new tellurium-based version may lead to a new generation of artificial retinas for people with blindness, potentially with infrared capabilities. This isn't just a vision-restoring device. It's potentially the first step toward bionic eyes, with infrared 'super sight'. It's an intersection of nanotech, neuroscience, and materials science, with real implications for medicine, military, and even human enhancement. The study has been published in the journal Science.

Apple Watch 圈圈真的準？美國有研究指 Apple Watch 部份運動數據追蹤表現準度不足
Yahoo購物節，6月2至13日正式舉行！集合全球精選著數的網上大型購物節：波鞋低至36折、手袋低至4折、自助餐半價、旅遊產品買一送一等，更有獨家優惠為您而設，把握限時兩星期優惠，1Click買盡全世界！ 早前消委會就發表智能手錶評測報告，強調智能手錶、手環的運動數據都是估算，只適宜作參考之用。其實智能手錶在追蹤不同數據時準度的確存在著誤差。最近美國就有研究指 Apple Watch 於運動時記錄燃燒了多少卡路里的數據，準度並不是想像中的高。 美國密西西比大學的研究人員做了一個關於 Apple Watch 的研究，分析了 56 數據得出一個整合分析，並以 Apple Watch 每一項的表現都與標準的醫療級工具進行了比較。結果顯示 Apple Watch 於測量心率及步數方面極大部份情況下是準確的。研究人員指，測心率與步數的平均絕對百分比誤差（即衡量準確度的標準指標）分別為 4.43% 與 8.17%，然而估算燃燒了卡路里數據表現就達 27.96%。對於一般大眾買到的穿戴式裝置而言，低於 10% 的誤差值表現已被視為「十分優秀」，但研究團隊測試 Apple Watch 在走路、跑步、混合強度訓練和踩單車等多種活動中計算用戶燃燒了多少卡路里的數據時，卻發現其估算值大幅超出可接受範圍。 不過研究人員同時指出，這個數據本身就相當難以估算，因為涉及許多變數如體重及運動方式等等。因此，不要把每個數字都當作 100% 準確，而是可當成其中一種鼓勵的工具，達至恆常運動、保持追蹤習慣並維持動力。團隊還指出，目前 Apple Watch 的準確度已提高了不少，顯示蘋果在硬體及演算法方面都在逐步改進，而指出弱點可幫助開發者獲得更真實的回應建議，協助他們進一步研究，以製出更好的感應器或演算法，提升智能手錶追蹤健康數據的表現。 更多內容： 9to5mac 消委會試智能手錶運動偵測，Garmin 最貴最高分，一款千元級高評分！Apple、Samsung、華為各有高低 智能手錶推薦 2025 | Apple、三星、Garmin 如何選？三鐵、跑山、單車各有不同，睇清楚點揀！ 緊貼最新科技資訊、網購優惠，追隨 Yahoo Tech 各大社交平台！ 🎉📱 Tech Facebook： 🎉📱 Tech Instagram： 🎉📱 Tech WhatsApp 社群： 🎉📱 Tech WhatsApp 頻道： 🎉📱 Tech Telegram 頻道：

Chinese Startup Trials First AI Doctor Clinic in Saudi Arabia
A Chinese startup has opened the world's first clinic in Saudi Arabia where artificial intelligence diagnoses patients, a key step in replacing human doctors as the first line of medical treatment. Synyi AI, a Shanghai-based medical technology company, launched the trial program in Saudi Arabia's eastern Al-Ahsa region in April in collaboration with the country's Almoosa Health Group. The pilot will see a virtual AI doctor making diagnoses and prescriptions to patients on its own, through interactions similar to dealing with a human doctor.
