- A joint team from KAIST, Yonsei University, and other collaborators develops a ‘universal charge injector’ that injects charge into two different types of ultrathin semiconductors using a single material
- A single injector material replaces separately optimized contacts for n-type and p-type semiconductors, boosting the maximum drive current of p-type transistors by more than 1,000-fold over conventional devices
- Opens the door to three-dimensional integration by stacking atomically thin semiconductors in multiple layers, expected to be used in next-generation AI and low-power semiconductors
Kyoto, Japan -- You may not know what roll waves are, but you've probably seen them on a rainy day. When it rains, these traveling waves appear on steep asphalt pavements, slowly making their way down the slope. Because roll waves propagate without deforming and are typically characterized by abrupt discontinuities, they play an important role in hydraulic engineering. Understanding unsteady flows like roll waves is crucial for the design, management, and safety of hydraulic structures such as dam spillway chutes.
However, despite one accurate line of research developed by mathematicians, the partial differential equations governing roll waves have remained a niche and "astonishingly" under-explored area of research, according to an international team of scientists at Kyoto University and German Jordanian University. This group realized that a rigorous mathematical investigation was not only compelling, but unavoidable.
"We noticed the striking gap between the mathematical and visual beauty of roll‑wave phenomena, and the civil engineering community's persistently superficial understanding of them," says first author Koichi Unami. "It became difficult to ignore how confidently steady‑state assumptions were repeated despite clear evidence to the contrary."
University of Melbourne Emeritus Professor Graeme Clark AC – whose breakthroughs have brought the gift of hearing to over 650,000 people globally – has been jointly awarded the 2026 Honda Prize.
The Prize has been awarded jointly to surgeon and scientist Professor Clark and Austrian electrical engineer Dr Ingeborg Hochmair. Working independently, both spearheaded the research and development, clinical application and worldwide adoption of the multichannel cochlear implant, commonly known as the bionic ear.

While the roles of parents in a child's education are well-studied, new research is taking a look at the role a sibling plays in collaborating on educational projects, and they found a few key roles often developed in this working relationship
Artificial intelligence (AI) scribes can reduce the time physicians spend documenting patient visits by 69.1% during simulated primary care appointments, according to research led by University of Toronto PhD student LaShawn Murray.
The study — published in the journal JAMIA Open, and co-authored with University of Toronto professor Enid Montague and Dr. Onil Bhattacharyya of Women’s College Hospital — involved nine physicians completing simulated patient encounters both with and without the use of AI scribes. These digital tools are capable of recording audio and using it to generate structured, regulatory-compliant clinical notes for a patient’s medical chart — the record physicians use to document their care.
The researchers used video recordings of each appointment to analyze how physicians spent their time. They found that when the scribes were in use, the doctors spent significantly less time documenting.
