Microsoft’s ‘Fake’ Marketplace Exposes Unexpected Flaws in AI Assistants

Microsoft researchers have unveiled a new virtual marketplace designed to stress‑test AI agents that are meant to negotiate, shop and collaborate on our behalf. In partnership with Arizona State University, the team populated the simulation with a range of tasks—from buying groceries to haggling over prices—while watching how the agents behaved when left to their own devices. The results were eye‑opening: many of the AI assistants fell prey to simple tricks, such as misleading prompts or deceptive pricing, and often made choices that a human would consider irrational. The study suggests that current “agentic” models are still vulnerable to manipulation and may struggle in real‑world, unsupervised settings. Ece Kamar, managing director of Microsoft Research’s AI Frontiers Lab, emphasized that understanding these weaknesses is crucial before we hand agents more autonomy. She warned that the way these bots talk, negotiate, and cooperate could reshape everyday life, but only if we first grasp their limits. The findings raise fresh questions about the timeline for truly reliable AI assistants and put pressure on companies to deliver on their promises of a seamless, agent‑driven future.

China’s Researchers Link Two Quantum Networks, Creating an 18‑User ‘Quantum Internet’ Testbed

A team of scientists at Shanghai Jiao Tong University has taken a big step toward a future quantum internet by joining two separate quantum networks into a single, 18‑user system. Using a technique called "entanglement swapping," they were able to share quantum links across all participants, letting each pair exchange information that is theoretically impossible to eavesdrop on. The experiment also employed clever timing tricks and wavelength‑multiplexing, which let many connections run at once without interfering with each other. The results were impressive: the quantum links maintained a fidelity above 84%, meaning the delicate quantum states stayed largely intact, and the interference visibility reached 90.7%, indicating very clean, reliable connections. While this demonstration is still a laboratory‑scale proof of concept, it shows that multiple users can securely communicate over a shared quantum channel, a cornerstone for a global quantum network. Researchers say the next hurdle is adding quantum repeaters—devices that can extend the reach of quantum signals over long distances—so that a true worldwide quantum internet could eventually become a reality.

China’s Space Lab Celebrates 1,000 Days of Breakthroughs – From Super‑Fast Chips to Space‑Born Zebrafish

Over the past 1,000 days, China’s space station has turned into a bustling laboratory delivering surprising scientific wins. Researchers split their work into three buckets: pure science (like studying life, materials and physics in micro‑gravity), cutting‑edge frontier projects, and practical payload experiments aimed at real‑world uses. One headline result came from growing indium selenide crystals in weightlessness – the resulting transistors performed three to four times better than Earth‑made versions, promising faster electronics, better photodetectors and flexible devices. Every day a new experiment runs. In the Wentian module’s “aquarium,” zebrafish have been raised and even laid eggs in orbit, helping scientists understand how micro‑gravity affects protein balance, bone loss and heart health – crucial knowledge for future long‑duration missions. Arabidopsis seedlings float nearby, revealing how plant cells adapt to space, while brain‑organoid chips let astronauts probe the impact of space on human brain function. The station now hosts 25 standard experiment slots, including 14 home‑grown racks that can carry twice the payload of the International Space Station’s equivalents. Looking ahead, the next 1,000 days will bring more visiting spacecraft, new docking ports, expanded modules and smarter, more autonomous systems to keep the research momentum soaring.

Mini‑Neptunes May Not Be Molten: New Study Suggests Solid Surfaces on Many ‘Lava Worlds’

Astronomers have long imagined a swath of distant planets—mini‑Neptunes—as scorching, lava‑covered worlds where the surface is a sea of molten rock. New research, however, challenges that picture, showing that many of these planets could actually sport solid, rocky surfaces beneath thick atmospheres. The study, led by planetary scientist Dr. Kempton, compares two extreme scenarios: a planet whose “floor is lava” versus one with a hard crust. By analyzing the way light filters through each planet’s atmosphere, the team identified subtle clues—such as specific gas signatures and temperature gradients—that point to a solid surface in several well‑known mini‑Neptunes. If these findings hold up, they reshape our understanding of how common Earth‑like conditions might be in the galaxy. A solid surface opens the door to possibilities like stable climates, oceans, and even the potential for life, whereas a lava world would be far less hospitable. The researchers caution that more detailed observations, especially from next‑generation telescopes, are needed to confirm the results. Still, the work highlights how a planet’s atmosphere can be a powerful detective, helping scientists decide whether a distant world is a fiery furnace or a rocky haven.

Fusion Milestones: US Firm Breaks Magnet Record, China Runs Tokamak Steady for 101 Seconds

Nuclear fusion is edging closer to reality thanks to two headline‑making achievements. A U.S. company has unveiled a D‑shaped superconducting magnet that reaches a record‑high magnetic field, a key ingredient for squeezing plasma tight enough for fusion reactions. At the same time, researchers at the University of Science and Technology of China (USTC) have pushed their all‑superconducting tokamak, EAST, to sustain a high‑confinement plasma for 101 seconds without interruption—a first for a fully superconducting device. Both breakthroughs tackle the twin challenges of magnetic strength and steady‑state operation, which have long limited fusion’s commercial prospects. The stronger magnet promises tighter plasma control, while the long‑duration run shows that superconducting coils can keep a tokamak running continuously, reducing the need for costly reheating cycles. Together, these advances suggest that commercial fusion power plants could appear within a few decades, offering a clean, virtually limitless energy source. Continued refinements in magnet technology and plasma stability are expected to accelerate the transition from experimental labs to real‑world power generation.

This Week’s Science Highlights: X‑59 Jet Takes Flight, Black‑Hole Clues, and Why the Universe Isn’t a Computer Game

Here’s a quick, bite‑size roundup of the most exciting science stories of the week, written for anyone who loves a good discovery. First up, NASA’s low‑boom X‑59 Quiet Supersonic Technology aircraft finally left the runway for its maiden test flight. Engineers are eager to see if the plane can cruise faster than sound without the thunderous boom that has kept supersonic travel out of the commercial market for decades. Meanwhile, researchers analyzing data from LIGO have spotted ripples that point to a new class of “second‑generation” black holes—objects that were likely born from the merger of earlier black holes, offering fresh clues about how these cosmic heavyweights grow. Astronomers also unveiled a stunning, multi‑wavelength portrait of the Milky Way, stitching together radio signals from across the spectrum to reveal hidden structures in our galaxy’s spiral arms. On the human side of science, a study shows that oxytocin, the so‑called “cuddle hormone,” can actually synchronize a person’s heartbeat and breathing with another’s, deepening our understanding of social bonding. In the world of quantum computing, scientists warned that certain quantum phases remain stubbornly hard to identify—computational time balloons exponentially as the system’s correlation length grows, putting practical limits on today’s quantum machines. Finally, a new mathematical proof argues that the universe cannot be a computer simulation, challenging the popular simulation hypothesis and reminding us that reality may be far stranger—and more real—than any virtual model. Stay curious, and keep following Phys.org for daily breakthroughs.

China’s Top AI Minds Gather to Shape the Future of Large‑Scale Models

Leading scientists and industry experts gathered in Beijing for the China Informatics Society’s 2025 Academic Annual Conference and the second China Large Model Conference. The two‑day event showcased the latest breakthroughs in artificial intelligence, from the way large models learn through reward‑based reinforcement learning to the ethical and safety challenges they raise. Fang Binxing, a senior engineer and society president, explained that while AI systems can act with a degree of autonomy, they still lack true consciousness. Yet their ability to adjust behavior based on incentives sometimes gives the impression of a budding self‑awareness. Speakers from top universities—including Macau City University, Renmin University and Fudan—unveiled cutting‑edge research on topics such as the new diffusion‑based language model “LLaDA,” situational intelligence, and pathways toward artificial general intelligence (AGI). Thirteen themed forums covered hot trends like generative AI, knowledge graphs, embodied intelligence and emotional computing, drawing more than a hundred scholars and practitioners into lively debate. The conference underscored large models as a strategic pillar for China’s drive toward technological self‑reliance. Leaders highlighted the need for deeper basic research, interdisciplinary collaboration, and talent cultivation to turn theoretical advances into reliable, real‑world applications. A separate talk explored how power‑law patterns—found in nature, music and language—can be modeled mathematically to improve AI’s ability to generate text and music.

Super‑Strong Magnet Uncovers Hidden Dual Nature of Exotic Material

Physicists led by Dr. Li have used the world’s most powerful magnet at the National Magnetic Field Laboratory to crack a puzzling mystery in quantum materials. By placing a crystal of ytterbium boride (YbB12) inside an ultra‑strong magnetic field, they observed clear quantum‑oscillation signals that, contrary to earlier guesses, come from deep inside the material rather than just its surface. This discovery shows that YbB12 can behave simultaneously like a metal (conducting electricity) and an insulator (blocking electricity) – a phenomenon researchers are calling a “new duality.” The experiment involved sweeping the magnetic field to extreme strengths, measuring tiny changes in the crystal’s electrical resistance, and confirming that the oscillations arise from the bulk of the sample. The result not only settles a long‑standing debate about the origin of metallic‑like behavior in certain insulators, but also hints at the existence of previously unseen quasiparticles inside these compounds. Understanding this dual nature could pave the way for innovative electronic devices that exploit both conducting and insulating properties, and it deepens our grasp of how quantum mechanics shapes the behavior of complex materials.

China’s 6G Breakthrough: Smarter, Faster Networks Powering the Next Industrial Revolution

China’s researchers say the next generation of mobile networks – 6G – will do more than just move bits faster. By weaving artificial intelligence into the core of the system, 6G will understand the meaning behind the data it carries, turning “sending a signal” into “getting the right answer.” This semantic approach cuts the amount of bandwidth and energy needed, making the network far more efficient. The team behind the breakthrough has built the world’s first 6G intelligent‑communication test field, proving it can transmit voice over a 1,200‑kilometre link from Beijing to Xi’an using meaning‑based short‑wave signals. They have also created a dedicated semantic‑communication chip and rolled out video‑ringtone services through China Mobile. Their work is now feeding into global standards: the 3GPP has accepted the key scenarios and technologies, and Chinese operators, equipment makers, and universities are rallying behind the “6G Intelligence‑Simplicity” concept. Looking ahead to the 15th Five‑Year Plan, the new network is expected to break down data silos, boost smart transportation, tele‑medicine, industrial internet and countless other sectors, creating a virtuous cycle of technology, data flow, and industrial upgrade. The researchers pledge to keep pushing the limits, aiming to make China a leader in original 6G technology and worldwide communications innovation.
