The gold standard: Researchers end 20-year spin debate on gold surface with definitive, full-map quantum imaging

Summary: Researchers at the Institute for Molecular Science (IMS) have definitively resolved a two-decade-long controversy regarding the direction of electron spin on the surface of gold. Using a state-of-the-art Photoelectron Momentum Microscope (PMM) at the UVSOR synchrotron facility, the team captured complete two-dimensional snapshots of the Au(111) Shockley surface state, mapping both the electron's spin (its intrinsic magnetic property) and its orbital shape in a projection-based measurement. The experiment unambiguously confirmed the Rashba effect--where an electron's motion is coupled to its spin--by assigning a clockwise ...

Through the wires: Technology developed by FAMU-FSU College of Engineering faculty mitigates flaws in superconducting wires

When current flows through a wire, it doesn’t always have a perfect path. Tiny defects within the wire mean current must travel a more circuitous route, a problem for engineers and manufacturers seeking reliable equipment. Through a partnership with industry, researchers at the FAMU-FSU College of Engineering and Florida State University’s Center for Advanced Power Systems and the National High Magnetic Field Laboratory have supported the development of a design that uses multiple strands of superconducting tape to create a cable, minimizing ...

Using robotic testing to spot overlooked sensory deficits in stroke survivors

A decade ago, at age 55, Don Lewis suffered a stroke in his sleep. When he woke up, he couldn’t move his left arm or leg. Lewis’ neighbor realized his truck hadn’t moved in two days and called 911 for a welfare check. When paramedics found him, he was paralyzed on one side. “At the hospital, they told me an aneurysm caused my stroke,” he said. He would remain there for two months, and after extensive physical therapy, Lewis regained use of his left leg. His left arm remains paralyzed. “I ...

How AI can rig polls

Public opinion polls and other surveys rely on data to understand human behavior. New research from Dartmouth reveals that artificial intelligence can now corrupt public opinion surveys at scale—passing every quality check, mimicking real humans, and manipulating results without leaving a trace. The findings, published in the Proceedings of the National Academy of Sciences, show just how vulnerable polling has become. In the seven major national polls before the 2024 election, adding as few as 10 to 52 fake AI responses—at five cents each—would have flipped the predicted outcome. Foreign adversaries could easily exploit this weakness: ...

Bridging the gap to bionic motion: challenges in legged robot limb unit design, modeling, and control

In recent years, robots have increasingly become integral in enhancing human life, particularly with the growing demand for mobile robots with high payload-to-weight ratios and dynamic capabilities. Traditional wheeled or tracked robots are difficult to operate stably in complex real-world environments, which has driven research on legged robots. Legged robots leverage their distinctive “leg” structures to traverse obstacles and adapt to uneven terrain, demonstrating exceptional mobility when confronted with pronounced undulations or soft ground. ...

We should talk more at school: Researchers call for more conversation-rich learning as AI spreads

Generative Artificial Intelligence could result in a renewed emphasis on conversational approaches to teaching, researchers say, as chatbots make it easier to bypass recall-based learning and test the limits of traditional exams. In a new conceptual paper, researchers at the University of Cambridge argue that AI raises questions for aspects of traditional models of education which focus on absorbing and memorising information. The authors suggest that AI, like many earlier communications technologies, is forcing a rethink ...

Reading a quantum clock costs more energy than running it, study finds

A study led by the University of Oxford has identified a surprising source of entropy in quantum timekeeping - the act of measurement itself. In a study published today (14 Nov) in Physical Review Letters, scientists demonstrate that the energy cost of reading a quantum clock far outweighs the cost of running it, with implications for the design of future quantum technologies. Clocks, whether pendulums or atomic oscillators, rely on irreversible processes to mark the passage of time. At the quantum scale, where such processes are weak or nearly absent, timekeeping becomes much more ...

AI at the speed of light just became a possibility

Tensor operations are the kind of arithmetic that form the backbone of nearly all modern technologies, especially artificial intelligence, yet they extend beyond the simple maths we’re familiar with. Imagine the mathematics behind rotating, slicing, or rearranging a Rubik’s cube along multiple dimensions. While humans and classical computers must perform these operations step by step, light can do them all at once. Today, every task in AI, from image recognition to natural language processing, relies on tensor operations. However, the explosion of ...

Microrobots finding their way

Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel. These drugs spread throughout the entire body, meaning a high dose must be administered to ensure that the necessary amount reaches the thrombus. This can cause serious side effects, such as internal bleeding. Since medicines are often only needed in specific areas of the body, medical research has long been searching for a way to use microrobots to deliver pharmaceuticals to where they need to be: in the case of a stroke, directly to the stroke-related thrombus. Now, a ...

Systematic review of multimodal physiological signals from wearable sensors for affective computing

Affective computing, proposed by Picard in 1997, aims to endow computational systems with the ability to recognize, interpret, and respond to human emotions. Early studies relied primarily on behavioral cues such as facial expressions and voice tone for modelling affective states. Affective computing has entered a new phase—wearable devices are capable of continuously acquiring multimodal physiological signals from multiple sensor channels that differ in terms of sampling frequency, physiological origin, and signal characteristics.

Scientists make dark exciton states shine, unlocking new frontiers for nanotechnology

New York, November 12, 2025 — A research team at the City University of New York and the University of Texas at Austin has discovered a way to make previously hidden states of light, known as dark excitons, shine brightly, and control their emission at the nanoscale. Their findings, published today in Nature Photonics, open the door to faster, smaller, and more energy-efficient technologies. Dark excitons are exotic light-matter states in atomically thin semiconductors that typically remain invisible because they emit light very weakly. These states, however, are highly ...
