Published New strategy reveals 'full chemical complexity' of quantum decoherence



Scientists have developed a method to extract the spectral density for molecules in solvent using simple resonance Raman experiments -- a method that captures the full complexity of chemical environments.
Published Unveiling molecular origami: A breakthrough in dynamic materials



A research team has unveiled a remarkable breakthrough in the form of a two-dimensional (2D) Metal Organic Framework (MOF) that showcases unprecedented origami-like movement at the molecular level. This pioneering study represents a significant leap forward in the field of dynamic materials, while also hinting at futuristic applications in metamaterials and quantum computing.
Published Filming the microscopic flow of hydrogen atoms in a metal



Using conventional X-rays and lasers to detect the atomic state of hydrogen is challenging, given its small size. A group of researchers may have overcome this barrier by unveiling a new visualization technique that employs an optical microscope and polyaniline to paint a better picture of how hydrogen behaves in metals.
Published Machine learning boosts search for new materials



During X-ray diffraction experiments, bright lasers shine on a sample, producing diffracted images that contain important information about the material's structure and properties. But conventional methods of analyzing these images can be contentious, time-consuming, and often ineffective, so scientists are developing deep learning models to better leverage the data.
Published Clinicians could be fooled by biased AI, despite explanations



A new study finds that clinicians were fooled by biased AI models, even with provided explanations for how the model generated its diagnosis.
Published AI's memory-forming mechanism found to be strikingly similar to that of the brain



An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published Artificial intelligence can predict events in people's lives



Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Computational model captures the elusive transition states of chemical reactions



Researchers developed a way to quickly calculate the transition state structure of a chemical reaction, using machine-learning models.
Published Ultrafast lasers map electrons 'going ballistic' in graphene, with implications for next-gen electronic devices



Research reveals the ballistic movement of electrons in graphene in real time. The observations could lead to breakthroughs in governing electrons in semiconductors, fundamental components in most information and energy technology.
Published Newly developed material gulps down hydrogen, spits it out, protects fusion reactor walls



A recent advance could enable more efficient compact fusion reactors that are easier to repair and maintain.
Published A promising pairing: Scientists demonstrate new combination of materials for quantum science



For the first time, scientists publish results on a new chip composed of diamond and lithium niobate. The results demonstrate the combination as a promising candidate for quantum devices.
Published Deep neural networks show promise as models of human hearing



In the largest study yet of deep neural networks trained to perform auditory tasks, researchers found most of these models generate internal representations that share properties of representations seen in the human brain when people are listening to the same sounds.
Published Ultra-hard material to rival diamond discovered



Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond, as the hardest material on earth, a study says. Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials -- known as carbon nitrides -- were tougher than cubic boron nitride, the second hardest material after diamond.
Published Hallmark quantum behavior in bouncing droplets



In a study that could help fill some holes in quantum theory, the team recreated a 'quantum bomb tester' in a classical droplet test.
Published Artificial intelligence systems excel at imitation, but not innovation



Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation, researchers have found.
Published Chance twists ordered carbon nanotubes into 'tornado films'



Scientists have developed two new methods to create ordered carbon nanotube films with either a left- or right-handed chiral pattern.
Published Hybrid device significantly improves existing, ubiquitous laser technology



Researchers have developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.
Published ChatGPT often won't defend its answers -- even when it is right



ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong.
Published North Korea and beyond: AI-powered satellite analysis reveals the unseen economic landscape of underdeveloped nations?



A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions with limited statistical data (e.g., North Korea), supporting international efforts to propose policies for economic growth and poverty reduction in underdeveloped countries. The research team plans to make this technology freely available for use to contribute to the United Nations' Sustainable Development Goals (SDGs).
Published Polaritons open up a new lane on the semiconductor highway



On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.'
