A team of researchers has unveiled a breakthrough in X‑ray astronomy: a high‑resolution telescope built with ultra‑precise electroformed nickel mirrors. In laboratory tests, the instrument could spot a 3.5 mm object from a kilometer away, a level of detail previously only imagined for space‑based observatories. What makes this achievement especially notable is the creation of the first ground‑based system capable of accurately evaluating the performance of such telescopes at hard X‑ray energies. Using a parallel X‑ray beam, scientists verified the mirror’s sharpness and identified the main obstacle to even finer images—tiny surface imperfections that run along the mirror’s length. With this knowledge, engineers now have a clear target for the next generation of mirrors. After the successful Earth‑based validation, the telescope rode aboard the FOXSI‑4 sounding rocket, confirming its capabilities in space. The team is already planning an upgraded version for the upcoming FOXSI‑5 mission, and the technology shows promise for miniaturized versions that could fit on CubeSats, opening new doors for affordable, high‑resolution X‑ray astronomy.
Read moreA research team at the University of Science and Technology of China has unveiled a new analog‑to‑digital converter (ADC) that shatters previous speed limits. Built on a 22‑nm CMOS process, the tiny chip (just 0.0022 mm²) can sample signals anywhere from 500 MS/s up to a staggering 2.5 GS/s, making it ideal for AI, ultra‑fast wireless, and high‑bandwidth wired links. Unlike traditional ADCs that rely on bulky analog amplifiers, this design uses a reset‑table ring voltage‑controlled oscillator (R‑RVCO) that stays mostly digital, simplifying the circuit and improving power efficiency. Innovative tricks—such as adaptive reset matching, dynamic switch buffering, and phase‑folding—boost phase extraction while keeping hardware lean. At a 2 GS/s sampling rate the chip delivers a signal‑to‑noise‑and‑distortion ratio of 39.1 dB and a Walden figure of merit of just 31.3 fJ per conversion step, figures that rival or surpass many existing solutions. The researchers also created a unified behavioral model to pinpoint why earlier VCO‑based ADCs hit a GHz ceiling, then engineered a discrete‑time open‑loop architecture that cuts phase‑noise and quantization errors, gaining roughly 3 dB in SNR. The breakthrough promises faster, more reliable data conversion for the next generation of high‑speed electronics.

Quantum computers promise lightning‑fast calculations, but they’ve been plagued by a mysterious problem: the data they store can vanish without warning. Now a team at Norway’s University of Science and Technology has unveiled a breakthrough method that can spot these losses as they happen—over a hundred times faster than any previous technique. By continuously monitoring tiny fluctuations in the relaxation rates of superconducting qubits, the researchers can map exactly when and where information disappears. This real‑time insight gives engineers a clear picture of the hidden noise that derails quantum operations, opening the door to smarter error‑correction strategies and more stable machines. The study, published in *Physical Review X*, demonstrates that adaptive tracking can keep pace with the rapid dynamics inside a quantum chip, turning a long‑standing blind spot into a diagnostic window. If the approach scales, it could accelerate the race toward practical, large‑scale quantum computers that are reliable enough for real‑world applications such as drug discovery, climate modeling, and secure communications.
Read moreChina has finished building the world’s largest, most advanced 5G network and is now racing ahead with 6G research, which promises speeds up to 1 Tbps—about 50 times faster than 5G. The 2025 Government Work Report officially placed 6G at the heart of future industry plans. To support these next‑gen services, the country is overhauling its backbone and metropolitan networks: 25 Gbps will become the new norm for city‑level links, while 100‑400 Gbps will dominate core and aggregation layers. A key driver is the exploding demand from AI‑powered data centers. As cloud, IoT and AI workloads surge, the need for ultra‑high‑speed, low‑latency connections has pushed global optical‑module sales past $23 billion in 2025—a 50 % year‑on‑year jump, with Ethernet modules alone hitting $17 billion. New silicon‑photonic and low‑power‑optical (LPO, CPO) technologies are emerging to keep power use and costs down. On the consumer side, China’s FTTR (Fiber‑to‑the‑Room) rollout reached nearly 60 million users by the end of 2025, a 70 % increase from the previous year, and the market for access‑side optical modules is projected to grow to $2.3 billion by 2030. Meanwhile, the nation is expanding 5G‑A coverage with half a million new base stations and laying the groundwork for 6G standards, submarine cable cooperation, and even space‑based optical links for satellite‑ground communication. All these moves position China at the forefront of the global race for faster, smarter connectivity.

A wave of optimism is sweeping the fusion industry, powered by three key breakthroughs: faster computer chips, smarter artificial‑intelligence tools, and ultra‑strong superconducting magnets. These advances let engineers design more sophisticated reactors, run realistic simulations, and control plasma with unprecedented precision. The excitement got a real boost at the end of 2022 when a U.S. Department of Energy lab announced it had achieved scientific breakeven—producing more energy from a fusion reaction than the lasers used to ignite it. While commercial breakeven—where a plant generates more power than it consumes—is still years away, the milestone proved the core science works. Among the companies that have each secured over $100 million in funding, TAE Technologies stands out. Founded in 1998 as Tri Alpha Energy, TAE uses a “field‑reversed configuration” that spins plasma into a cigar shape. By firing particle beams into the colliding plasma, they keep it stable longer, giving fusion more time to generate heat that can spin a turbine. Shine Technologies takes a more cautious route. Rather than rushing to sell electricity, it’s first offering neutron‑testing services and producing medical isotopes, while also developing technology to recycle radioactive waste. Shine hasn’t committed to a single reactor design yet, but it’s building the expertise it will need when the next generation of fusion plants finally goes live.
Read moreLiu Ling believes China is uniquely positioned to become a world leader in AI‑driven medical care. With a population of over 1.4 billion, the country offers an enormous pool of diverse and complex health cases, creating a rich tapestry of clinical scenarios for AI to learn from. This massive, real‑world data set gives developers a solid foundation to train smarter, more accurate algorithms. At the same time, the Chinese government is actively backing the sector with supportive policies, funding, and regulatory guidance, while doctors, hospitals, and patients alike are increasingly aware of the benefits AI can bring to diagnosis, treatment planning, and patient monitoring. All these forces—vast data, policy support, and growing demand—are converging to accelerate the growth of “AI + medical care” in China. Philips, a global health‑technology leader, has pledged to work hand‑in‑hand with local partners to speed up innovation, share expertise, and bring cutting‑edge AI solutions to Chinese hospitals. The company’s goal is to help China reach new heights in the global smart‑medicine arena, turning domestic demand into worldwide value and setting a benchmark for the future of healthcare everywhere.
Read moreAt a national nuclear safety event in Guangdong on April 10, officials announced that China now operates 62 nuclear reactors and holds construction permits for 39 more – together accounting for more than half of all new nuclear projects worldwide. The country expects the operating fleet to hit 70 reactors by the end of 2026. Vice‑minister Dong Baotong, who also leads the National Nuclear Safety Administration, said China is at a pivotal moment: new technologies such as small modular reactors, advanced designs and even nuclear‑fusion are moving fast, while nuclear power is becoming a daily part of people’s lives. He stressed that scaling up must go hand‑in‑hand with rock‑solid safety, a political duty that will guide the nation through its 15th Five‑Year Plan. Guangdong, the province with the densest nuclear footprint, boasts a full‑chain industry—from design and equipment manufacturing to construction and operation. Provincial leader Zhang Hu highlighted the region’s comprehensive safety management system, which covers every stage of a plant’s life. The Daya Bay plant, the first large‑scale commercial reactor on the mainland, has run safely for 32 years, delivering more than 330 billion kWh to Hong Kong – roughly a quarter of the city’s electricity. CGN Chairman Yang Changli noted that all 28 of the company’s reactors logged zero unplanned shutdowns in 2025, underscoring China’s focus on safety as it expands its nuclear fleet.
