| Development of an artificial vision device capable of mimicking human optical illusions Posted: 29 Nov 2021 07:56 AM PST Researchers have developed an ionic artificial vision device capable of increasing the edge contrast between the darker and lighter areas of an mage in a manner similar to that of human vision. This first-ever synthetic mimicry of human optical illusions was achieved using ionic migration and interaction within solids. It may be possible to use the device to develop compact, energy-efficient visual sensing and image processing hardware systems capable of processing analog signals. |
| 'Magic wand' reveals a colorful nano-world Posted: 25 Nov 2021 12:48 PM PST Researchers describe a revolutionary imaging technology that compresses lamp light into a nanometer-sized spot. It holds that light at the end of a silver nanowire like a Hogwarts student practicing the 'Lumos' spell, and uses it to reveal previously invisible details, including colors, in nanomaterials such as carbon nanotubes. |
| We might not know half of what’s in our cells, new AI technique reveals Posted: 24 Nov 2021 12:39 PM PST Artificial intelligence-based technique reveals previously unknown cell components that may provide new clues to human development and disease. |
| Shifting colors for on-chip photonics Posted: 24 Nov 2021 12:39 PM PST Researchers have developed highly efficient, on-chip frequency shifters that can convert light in the gigahertz frequency range. The frequency shifters are easily controlled, using continuous and single-tone microwaves. |
| New chip hides wireless messages in plain sight Posted: 23 Nov 2021 10:14 AM PST Researchers have developed a method for incorporating security in the physical nature of the wireless transmission signal for 5G and future networks. |
| Origami, kirigami inspire mechanical metamaterials designs Posted: 23 Nov 2021 10:13 AM PST Researchers categorize origami- and kirigami-based mechanical metamaterials, artificially engineered materials with unusual mechanical properties, and subdivided them into rigid or deformable categories based on the elastic energy landscape. The researchers want to discover new designs, especially curved origami designs, hybrid origami-kirigami designs, modular designs, and hierarchical designs; to design for real-world applications, it will be helpful to explore materials with different properties such as thin or thick, soft or hard, and elastic or plastic. |
| Fighting blood diseases with artificial intelligence Posted: 22 Nov 2021 10:55 AM PST How can we better diagnose blood diseases? A research group aims to answer this question with artificial intelligence (AI). Their goal is to facilitate the time-consuming analysis of bone marrow cells under the microscope. The researchers developed the largest open-source database on microscopic images of bone marrow cells to date. They use it as the basis for an AI model with high potential for routine diagnostics. |
| Wearable device can detect and reverse opioid overdose Posted: 22 Nov 2021 10:54 AM PST Researchers have developed a wearable device to detect and reverse an opioid overdose. The device, worn on the stomach like an insulin pump, senses when a person stops breathing and moving, and injects naloxone, a lifesaving antidote that can restore respiration. |
