New study finds AI-generated empathy has its limits

ITHACA, N.Y. – Conversational agents (CAs) such as Alexa and Siri are designed to answer questions, offer suggestions – and even display empathy. However, new research finds they do poorly compared to humans when interpreting and exploring a user’s experience. CAs are powered by large language models (LLMs) that ingest massive amounts of human-produced data, and thus can be prone to the same biases as the humans from which the information comes. Researchers from Cornell University, Olin College and Stanford University tested this theory ...

AI and holography bring 3D augmented reality to regular glasses

Researchers in the emerging field of spatial computing have developed a prototype augmented reality headset that uses holographic imaging to overlay full-color, 3D moving images on the lenses of what would appear to be an ordinary pair of glasses. Unlike the bulky headsets of present-day augmented reality systems, the new approach delivers a visually satisfying 3D viewing experience in a compact, comfortable, and attractive form factor suitable for all-day wear. “Our headset appears to the outside world just like an everyday pair of glasses, but what the wearer sees through the lenses is an enriched world overlaid with vibrant, full-color 3D computed imagery,” said Gordon ...

Swarms of miniature robots clean up microplastics and microbes, simultaneously (video)

When old food packaging, discarded children’s toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. In a study in ACS Nano, researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused. Watch a video of them swarming. The size ...

Emergency department packed to the gills? Someday, AI may help

UCSF-led study finds artificial intelligence is as good as a physician at prioritizing which patients need to be seen first. Emergency departments nationwide are overcrowded and overtaxed, but a new study suggests artificial intelligence (AI) could one day help prioritize which patients need treatment most urgently. Using anonymized records of 251,000 adult emergency department (ED) visits, researchers at UC San Francisco evaluated how well an AI model was able to extract symptoms from patients’ ...

Using AI to predict GPA from college application essays

Jonah Berger and Olivier Toubia used natural language processing to understand what drives academic success. The authors analyzed over 20,000 college application essays from a large public university that attracts students from a range of racial, cultural, and economic backgrounds and found that the semantic volume of the writing, or how much ground an application essay covered predicted college performance, as measured by grade point average. Essays that covered more semantic ground predicted higher grades. Similarly, essays with smaller conceptual jumps between successive parts of ...

Quantum breakthrough: World’s purest silicon brings scientists one step closer to scaling up quantum computers

More than 100 years ago, scientists at The University of Manchester changed the world when they discovered the nucleus in atoms, marking the birth of nuclear physics. Fast forward to today, and history repeats itself, this time in quantum computing. Building on the same pioneering method forged by Ernest Rutherford – "the founder of nuclear physics" – scientists at the University, in collaboration with the University of Melbourne in Australia, have produced an enhanced, ultra-pure form of silicon that allows ...

Groundbreaking microcapacitors could power chips of the future

– By Alison Hatt In the ongoing quest to make electronic devices ever smaller and more energy efficient, researchers want to bring energy storage directly onto microchips, reducing the losses incurred when power is transported between various device components. To be effective, on-chip energy storage must be able to store a large amount of energy in a very small space and deliver it quickly when needed – requirements that can’t be met with existing technologies. Addressing this challenge, scientists ...

New quantum sensing scheme could lead to enhanced high-precision nanoscopic techniques

Researchers from the University of Portsmouth have unveiled a quantum sensing scheme that achieves the pinnacle of quantum sensitivity in measuring the transverse displacement between two interfering photons. This new technique has the potential to enhance superresolution imaging techniques that already employ single-photon sources as probes for the localization and tracking of biological samples, such as single-molecule localization microscopy with quantum dots. Traditionally, achieving ultra-high precision in nanoscopic techniques has been constrained by the limitations of standard imaging methods, such as the diffraction limit ...

Tweaking isotopes sheds light on promising approach to engineer semiconductors

Research led by scientists at the Department of Energy’s Oak Ridge National Laboratory has demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors. Partly because of semiconductors, electronic devices and systems become more advanced and sophisticated every day. That’s why for decades researchers have studied ways to improve semiconductor compounds to influence how they carry electrical current. One approach is to use isotopes to ...
