Core Insights - A research team from the University of California, Davis has developed a small imaging system called "DeepInMiniscope" that allows for high-resolution, non-invasive real-time observation of brain activity in mice [1][2] - The system is expected to open new pathways for neuroscience research and facilitate the development of new therapies for brain diseases [1] Group 1: Technology and Innovation - The DeepInMiniscope utilizes a novel mask design that integrates over 100 micro high-resolution lenses, employing neural networks to combine images from these lenses to reconstruct high-quality 3D images [1] - The neural network incorporates various machine learning methods to quickly and accurately restore fine structures in a larger 3D space [2] Group 2: Size and Usability - The new microscope measures only 3 square centimeters, approximately the size of a grape, and weighs about 10 grams, making it significantly smaller than previous devices [2] - Its ergonomic design allows for comfortable and safe use by mice during free movement, enhancing usability in behavioral studies [2] Group 3: Future Goals - The ultimate goal of the research is to develop a wireless device that is only 2 square centimeters in size, aimed at deepening the understanding of brain information processing and behavior mechanisms, as well as advancing the recognition and treatment strategies for brain diseases [2]

Core Insights - The National Institute of Standards and Technology (NIST) has developed a quantum device capable of simultaneously measuring current, resistance, and voltage within a single system, potentially simplifying quantum electrical standards operations and reducing research costs [1][2]. Group 1: Device Functionality - The new "one-box" measurement method allows for the integration of two quantum standards that traditionally required separate devices, which is a significant challenge due to the reliance on fragile quantum phenomena observable only at very low temperatures [1]. - The device utilizes a novel material that enables quantum properties to be achieved without the need for a magnetic field, allowing both quantum systems to operate simultaneously within the same low-temperature refrigerator [1]. Group 2: Measurement Accuracy - The team successfully obtained measurements for amperes, ohms, and volts with an error margin of only one millionth, showcasing the precision of the new device [1]. Group 3: Cost and Accessibility - This device is expected to lower the costs associated with using quantum electrical standards and make it more convenient for researchers worldwide to utilize [2].
