Researchers say ‘unusual’ metamaterial could double capacity of wireless networks

Credit: Pixabay/CC0 Public Domain Your office wall may play a part in the next generation of wireless communications. University of Toronto researchers George Eleftheriades and Sajjad Taravati have shown that reflectors made of metamaterials can channel light to enable more wireless data to be transmitted over a single frequency. They believe this newly realized property—called “full-duplex nonreciprocity”—could double the capacity of existing wireless networks. Their research is published in a paper in Nature Communications. “This is happening,” says Eleftheriades, a … Continue reading “Researchers say ‘unusual’ metamaterial could double capacity of wireless networks”

Exoskeleton research demonstrates the importance of training

Graduate student Guan Rong Tan walks in the ankle exoskeleton emulator in the Biomechatronics Laboratory. Credit: Guan Rong Tan and Michael Raitor Exoskeleton devices work, researchers say, for a variety of uses such as speeding up our walking or making running easier. Yet they don’t know what exactly makes exoskeletons effective. What is the benefit of customization, for example? And how much does simply getting used to the exoskeleton matter? Researchers in the Stanford Biomechatronics Laboratory at Stanford University examined … Continue reading “Exoskeleton research demonstrates the importance of training”

LEONARDO, the bipedal robot, can ride a skateboard and walk a slackline

Credit: California Institute of Technology Researchers at Caltech have built a bipedal robot that combines walking with flying to create a new type of locomotion, making it exceptionally nimble and capable of complex movements. Part walking robot, part flying drone, the newly developed LEONARDO (short for LEgs ONboARD drOne, or LEO for short) can walk a slackline, hop, and even ride a skateboard. Developed by a team at Caltech’s Center for Autonomous Systems and Technologies (CAST), LEO is the first … Continue reading “LEONARDO, the bipedal robot, can ride a skateboard and walk a slackline”

Smart robots do all the work at Nissan’s ‘intelligent’ plant

Robotic arms put in the electric vehicle powertrain into the Ariya model in the assembly line at Nissan’s Tochigi plant in Kaminokawa town, Tochigi prefecture, Japan, Friday, Oct. 8, 2021. Nissan’s “intelligent factory” hardly has any human workers. The robots do the work, including welding and mounting. They do the paint jobs and inspect their own paint jobs.

Artificial intelligence is now part of our everyday lives, and its growing power is a double-edged sword

AI-generated images of “a stained glass window with an image of a blue strawberry.” Credit: OpenAI A major new report on the state of artificial intelligence (AI) has just been released. Think of it as the AI equivalent of an Intergovernmental Panel on Climate Change report, in that it identifies where AI is at today, and the promise and perils in view. From language generation and molecular medicine to disinformation and algorithmic bias, AI has begun to permeate every aspect … Continue reading “Artificial intelligence is now part of our everyday lives, and its growing power is a double-edged sword”

Stanford PhD candidate Michael John Raitor tests out the augmented cane, created with way-finding capabilities similar to those used in autonomous vehicles. Credit: Andrew Brodhead Most know the white cane as a simple-but-crucial tool that assists people with visual impairments in making their way through the world. Researchers at Stanford University have now introduced an affordable robotic cane that guides people with visual impairments safely and efficiently through their environments. Using tools from autonomous vehicles, the research team has built the … Continue reading “Researchers build $400 self-navigating smart cane”

How the brain navigates cities: We seem to be wired to calculate not the shortest path but the ‘pointiest’ one

An MIT study suggests our brains are not optimized to calculate the shortest possible route when navigating on foot. In this figure, pedestrian paths are shown in red while the shortest path is in blue. Credit: MIT Everyone knows the shortest distance between two points is a straight line. However, when you’re walking along city streets, a straight line may not be possible. How do you decide which way to go? A new MIT study suggests that our brains are … Continue reading “How the brain navigates cities: We seem to be wired to calculate not the shortest path but the ‘pointiest’ one”

Rising tide of leaks threatens to inundate Facebook

In this file illustration photo taken in August 2021, the Facebook logo is seen on a smartphone in front of a computer screen in Los Angeles. Facebook held back from doing all it could to stop users from being radicalized and US election misinformation from flooding the social network, according to media reports Friday. An array of US news outlets cited documents from former Facebook worker Frances Haugen, adding to a series of critical revelations already published based on information … Continue reading “Rising tide of leaks threatens to inundate Facebook”
