A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.

Artificial intelligence (AI) may serve as a future tool for neurologists to help locate where in the brain a stroke occurred. In a new study, AI processed text from health histories and neurologic examinations to locate lesions in the brain. The study looked specifically at the large language model called generative pre-trained transformer 4 (GPT-4).

What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?

Quantum simulators are quantum systems that can be controlled exceptionally well. They can be used to indirectly learn something about other quantum systems, which cannot be experimented on so easily. Therefore, quantum simulators play an important role in unraveling the big questions of quantum physics. However, they are limited by temperature: They only work well, when they are extremely cold. Scientists have now developed a method to cool quantum simulators even more than before: by splitting a Bose-Einstein-condensate in half, in a very special way.

Engineers have uncovered an unexpected pattern in how neural networks -- the systems leading today's AI revolution -- learn, suggesting an answer to one of the most important unanswered questions in AI: why these methods work so well. The result not only illuminates the inner workings of neural networks, but gestures toward the possibility of developing hyper-efficient algorithms that could classify images in a fraction of the time, at a fraction of the cost.

Researchers have now developed standards and calibrations for optical microscopes that allow quantum dots to be aligned with the center of a photonic component to within an error of 10 to 20 nanometers (about one-thousandth the thickness of a sheet of paper). Such alignment is critical for chip-scale devices that employ the radiation emitted by quantum dots to store and transmit quantum information.

Researchers have conducted a series of participatory deliberation workshops in which the participants were asked to consider issues of future society and manufacturing, in general, and as they relate to hydrothermally produced porous glass. In workshops where the perspective of 'imaginary future generations' was adopted, participants' perceptions of the technology's feasibility and future potentiality changed significantly.

Scientists successfully addressed mathematical challenges in conventional Spectral Matrix analysis, used to analyze three-component seismic signals, by introducing time-delay components. The new technique enables the characterization of various polarized waves and the detection of seismic events that have previously gone unnoticed by conventional methods. These findings pave the way for improving a variety of applications, including earthquake detection.
