The lung is a complex organ whose main function is to exchange gases. It is the largest organ in the human body and plays a key role in the oxygenation of all the organs. Due to its structure, cellular composition and dynamic microenvironment, is difficult to mimic in vitro. A specialized laboratory of the ARTORG Center for Biomedical Engineering Research, University of Bern, … [Read more...] about Sophisticated lung-on-chip created

Anyone who's been to a concert knows that something magical happens between the performers and their instruments. It transforms music from being just "notes on a page" to a satisfying experience. A University of Washington team wondered if artificial intelligence could recreate that delight using only visual cues -- a silent, top-down video of someone playing the piano. The … [Read more...] about ‘Audeo’ teaches artificial intelligence to play the piano

UCLA materials scientists and colleagues have discovered that perovskites, a class of promising materials that could be used for low-cost, high-performance solar cells and LEDs, have a previously unutilized molecular component that can further tune the electronic property of perovskites. Named after Russian mineralogist Lev Perovski, perovskite materials have a crystal-lattice … [Read more...] about New way to power up nanomaterials for electronic applications

The modern world is powered by electrical circuitry on a "chip" -- the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 zettabytes (175trillion gigabytes) of new data. How can we ensure the security of sensitive data at such a high volume? And how can we address … [Read more...] about Breakthrough in quantum photonics promises a new era in optical circuits: Method to enable quantum optical circuits that use photons–heralds a new future for secure communication and quantum computing

Scientists at Tokyo Institute of Technology (Tokyo Tech) and NTT Corporation (NTT) develop a novel CMOS-based transceiver for wireless communications at the 300 GHz band, enabling future beyond-5G applications. Their design addresses the challenges of operating CMOS technology at its practical limit and represents the first wideband CMOS phased-array system to operate at such … [Read more...] about Pushed to the limit: A CMOS-based transceiver for beyond 5G applications at 300 GHz

University of Texas at Arlington researchers have developed a technique that programs 2D materials to transform into complex 3D shapes. The goal of the work is to create synthetic materials that can mimic how living organisms expand and contract soft tissues and thus achieve complex 3D movements and functions. Programming thin sheets, or 2D materials, to morph into 3D shapes … [Read more...] about Engineers develop programming technology to transform 2D materials into 3D shapes

Cryo-electron microscopy (cryo-EM) allows scientists to produce high-resolution, three-dimensional images of tiny molecules such as proteins. This technique works best for imaging proteins that exist in only one conformation, but MIT researchers have now developed a machine-learning algorithm that helps them identify multiple possible structures that a protein can take. Unlike … [Read more...] about Machine-learning model helps determine protein structures: New technique reveals many possible conformations that a protein may take

Researchers at Case Western Reserve University, using artificial intelligence (AI) to analyze simple tissue scans, say they have discovered biomarkers that could tell doctors which lung cancer patients might actually get worse from immunotherapy. Until recently, researchers and oncologists had placed these lung cancer patients into two broad categories: those who would benefit … [Read more...] about Using Artificial Intelligence to prevent harm caused by immunotherapy: Researchers discover biomarkers to identify lung cancer patients who could be made worse by same drugs that helps many others

A novel artificial intelligence (AI) approach based on wireless signals could help to reveal our inner emotions, according to new research from Queen Mary University of London. The study, published in the journal PLOS ONE, demonstrates the use of radio waves to measure heartrate and breathing signals and predict how someone is feeling even in the absence of any other visual … [Read more...] about Scientists propose new way to detect emotions using wireless signals

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare. Army researchers built the quantum sensor, which can sample the radio-frequency spectrum -- from zero frequency up to 20 GHz -- and detect AM and FM radio, Bluetooth, Wi-Fi and other … [Read more...] about New quantum receiver the first to detect entire radio frequency spectrum
