Chinese Scientists Use Quantum Entanglement to Super‑Charge Diamond Sensors

A team of Chinese researchers has taken a big step forward in quantum technology by using entanglement to make diamond‑based sensors far more powerful. In simple terms, they managed to “see” two tiny, normally invisible electron spins that sit right next to each other, something that has been a long‑standing challenge. By linking the spins through quantum entanglement, the sensors became about 3.4 times more sensitive than a single‑sensor setup, even when the surrounding environment was noisy. Even more impressive, the new system can track these fragile spin signals in real time and actively adjust to keep them stable. Why does this matter? The breakthrough proves that quantum entanglement can dramatically boost nanoscale sensing, turning diamonds—already known for their exceptional magnetic detection abilities—into ultra‑precise microscopes for the quantum world. Scientists can now study the tiniest magnetic fields in materials, biological molecules, and chemical reactions with unprecedented clarity. The work also lays important groundwork for building room‑temperature quantum computers using diamond nitrogen‑vacancy centers. In short, this discovery opens a new window for exploring quantum materials and could accelerate advances in physics, biology, chemistry, and future computing technologies.

How China Baowu Steel Is Building the Future with Digital Twin Technology

China’s push for an industrial internet has turned a handful of forward‑thinking companies into digital pioneers, and Baowu Steel is leading the charge. By creating a "digital twin"—a virtual replica of its massive 280,000 ㎡ plant—Baowu can watch every bolt, pipe and steel beam in real time. Using high‑precision 3D scanning (iTwin Capture) and advanced modeling tools, the company built a 260‑million‑point cloud that syncs with its BIM (Building Information Modeling) data. This virtual copy lets engineers assemble equipment, check for clashes, and plan installations long before a single worker steps on site. The result? Fewer on‑site errors, faster construction schedules, and a dramatic cut in rework. Beyond speed, the digital twin delivers big environmental wins. The plant now emits far less exhaust—saving roughly 12,000 tons of CO₂ each year—and keeps particulate matter well under national limits. Baowu’s success shows how marrying real‑world data with a living digital model can turn a traditional steel mill into an intelligent, low‑carbon factory. As edge computing and AI grow, such twins are set to become the operating system of modern industry, driving smarter decisions and greener outcomes across the globe.

Inside Shenzhen’s Cutting‑Edge Research Hub: From Synthetic Biology to Carbon‑Neutral Tech

At the heart of China’s push for high‑tech innovation, the Shenzhen Institute of Advanced Technology (SIAT) of the Chinese Academy of Sciences houses several fast‑growing research units. The Center for Synthetic Biological Evolution tackles big questions about how microbes evolve and interact with their surroundings, blending math‑driven models with synthetic‑biology tools to create new ways of studying life. Launched in 2018, the Institute of Advanced Materials Science and Engineering focuses on electronic materials—especially packaging and functional components that keep tomorrow’s gadgets running smoothly. After a grand opening in late 2018, it spent two years building its labs and officially began operations in November 2020. Responding to China’s climate goals, SIAT added the Institute of Carbon Neutrality Technology in June 2021; it concentrates on the science and engineering needed to cut emissions and support carbon‑neutral industries across the country, becoming fully operational in November 2022. A fourth unit, the Institute of Scientific Instruments, is currently in the planning stage, aiming to develop next‑generation measurement tools for all the other labs. Together, these centers turn Shenzhen into a powerhouse where biology, materials, and climate science converge to drive the next wave of sustainable, high‑tech breakthroughs.

Silent Plaque Sneaks Past Risk Scores: Half of Heart Attacks Hit ‘Low‑Risk’ Patients

A new study from Mount Sinai Hospital reveals a startling flaw in the tools doctors use to predict heart attacks. Researchers found that about 50 % of heart attacks occur in people who were previously labeled as “low risk” by standard calculators. The culprit? Hidden arterial plaque that doesn’t show up on routine risk assessments but can still rupture and trigger a blockage. By comparing medical records of thousands of patients with advanced imaging, the team discovered that many individuals deemed safe actually carried dangerous, silent buildups of cholesterol and calcium in their arteries. These findings suggest that current risk models, which rely heavily on factors like age, cholesterol levels, blood pressure, and smoking status, may overlook a critical piece of the puzzle. The authors recommend incorporating more sensitive imaging techniques—such as coronary CT scans—into routine screening for people with even modest risk factors. Doing so could catch the hidden plaque early, allowing doctors to intervene with lifestyle changes or preventive medication before a catastrophic heart attack occurs. The study underscores the need to rethink how we assess cardiovascular danger and to move toward more personalized, image‑guided heart‑health strategies.

Shougang Rolls Out New Low‑Carbon Steel Plant as China’s Carbon Market Booms

Shougang Co. is stepping up its green game to meet China’s expanding carbon‑market rules. The steelmaker will soon launch a 160‑ton electric‑arc furnace and related equipment that can cut the carbon footprint of its steel by more than 70 percent. The new plant will not only churn out greener steel, it will also serve as a test bed for cutting‑edge emissions‑reduction technologies and help build a Shougang‑branded low‑carbon product line. Beyond the furnace, Shougang is betting on renewable power. The company is adding solar panels and biomass energy to its mix and creating a smart digital platform to track and manage its carbon output in real time. Experts say the move reflects a broader shift in China’s climate policy, where higher carbon prices are opening lucrative markets for clean‑tech solutions. One example of that trend is Wan Jiang New Energy’s geothermal system, which now provides zero‑carbon heating for BMW’s Shenyang plant and saves about 18,000 tonnes of CO₂ each year. Across the country, projects that combine wind, solar, storage and green hydrogen are speeding up, offering clean‑energy options for heavy‑industry users. Shougang’s upgrades illustrate how traditional manufacturers are adapting to a low‑carbon future while tapping new business opportunities.
