| Designers find better solutions with computer assistance, but sacrifice creative touch Posted: 23 May 2022 12:07 PM PDT A computer-guided approach to design can propose more solutions and balance out human inexperience and design fixation. |
| Charting a safe course through a highly uncertain environment Posted: 23 May 2022 12:06 PM PDT Researchers have developed a trajectory-planning system for autonomous vehicles that enables them to travel from a starting point to a target location safely, even when there are many different uncertainties in the environment, such as unknown variations in the shapes, sizes, and locations of obstacles. |
| Twisted soft robots navigate mazes without human or computer guidance Posted: 23 May 2022 12:06 PM PDT Researchers have developed soft robots that are capable of navigating complex environments, such as mazes, without input from humans or computer software. |
| Using Artificial Intelligence to Predict Life-Threatening Bacterial Disease in Dogs Posted: 23 May 2022 10:50 AM PDT Veterinarians and researchers have developed a technique to predict leptospirosis in dogs through artificial intelligence. Leptospirosis is a life-threatening bacterial disease dogs can get from drinking contaminated water. |
| 'I don't even remember what I read': People enter a 'dissociative state' when using social media Posted: 23 May 2022 10:50 AM PDT Researchers found that people might not be 'addicted' to social media. Instead they get stuck in a state of dissociation, like what happens when you are reading a good book. |
| Novel AI algorithm for digital pathology analysis Posted: 23 May 2022 08:55 AM PDT Digital pathology is an emerging field which deals with mainly microscopy images that are derived from patient biopsies. Because of the high resolution, most of these whole slide images (WSI) have a large size, typically exceeding a gigabyte (Gb). Therefore, typical image analysis methods cannot efficiently handle them. Seeing a need, researchers developed a novel artificial intelligence (AI) algorithm based on a framework called representation learning to classify lung cancer subtype based on lung tissue images from resected tumors. |
| New recipe for restaurant, app contracts Posted: 23 May 2022 08:55 AM PDT A novel contract could help alleviate key sources of conflict between restaurants and food-delivery platforms. |
| Spinning is key for line-dancing electrons in iron selenide Posted: 23 May 2022 06:33 AM PDT Quantum physicists have answered a puzzling question at the forefront of research into iron-based superconductors: Why do electrons in iron selenide dance to a different tune when they move right and left rather than forward and back? In a new study, the researchers report the discovery of high-energy spin anisotropy that occurs concurrently with electronic nematicity in iron selenide. |
| Haptics device creates realistic virtual textures Posted: 21 May 2022 06:33 AM PDT Tactile sensation is an incredibly important part of how humans perceive their reality. Haptics or devices that can produce extremely specific vibrations that can mimic the sensation of touch are a way to bring that third sense to life. However, as far as haptics have come, humans are incredibly particular about whether or not something feels 'right,' and virtual textures don't always hit the mark. Now, researchers have developed a new method for computers to achieve that true texture -- with the help of human beings. Called a preference-driven model, the framework uses our ability to distinguish between the details of certain textures as a tool in order to give these virtual counterparts a tune-up. |
| Long-hypothesized 'next generation wonder material' created Posted: 21 May 2022 06:33 AM PDT New research fills a longstanding gap in carbon material science, potentially opening brand-new possibilities for electronics, optics and semiconducting material research. |
| Posted: 20 May 2022 11:46 AM PDT Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and directions. |
| Neuromorphic memory device simulates neurons and synapses Posted: 20 May 2022 10:29 AM PDT Researchers have reported a nano-sized neuromorphic memory device that emulates neurons and synapses simultaneously in a unit cell, another step toward completing the goal of neuromorphic computing designed to rigorously mimic the human brain with semiconductor devices. |
| Superconductivity and charge density waves caught intertwining at the nanoscale Posted: 20 May 2022 10:28 AM PDT Scientists discover superconductivity and charge density waves are intrinsically interconnected at the nanoscopic level, a new understanding that could help lead to the next generation of electronics and computers. |
| Interplay between charge order and superconductivity at nanoscale Posted: 20 May 2022 04:31 AM PDT Scientists have been relentlessly working on understanding the fundamental mechanisms at the base of high-temperature superconductivity with the ultimate goal to design and engineer new quantum materials superconducting close to room temperature. |
| Artificial intelligence model can predict whether Crohn disease will recur after surgery Posted: 10 May 2022 09:24 AM PDT Using an artificial intelligence (AI) tool that emulates how humans visualize and is trained to recognize and classify images, investigators constructed a model that predicts the postoperative recurrence of Crohn disease with high accuracy by evaluating histological images. The AI tool also revealed previously unrecognized differences in adipose cells and significant differences in the extent of mast cell infiltration in the subserosa, or outer lining of the intestine, comparing patients with and without disease recurrence. |
