How a slender, snake-like robot could give doctors new ways to save lives

Professor Jessica Burgner-Kahrs Credit: Nick Iwanyshyn You might call it “zoobotics.” Jessica Burgner-Kahrs, the director of the Continuum Robotics Lab at U of T Mississauga, and her team are building very slender, flexible and extensible robots, a few millimeters in diameter, for use in surgery and industry. Unlike humanoid robots, so-called continuum robots feature a long, limbless body—not unlike a snake’s—that allows them to access difficult-to-reach places. Consider a neurosurgeon who needs to remove a brain tumor. Using a traditional,…

Improving iOS Intangibles with Tactical | by Alaina Kafkes | May, 2021

Photo by Arnel Hasanovic on Unsplash In the days of lore and legend that precede my employment, Medium operated under the decentralized organizational philosophy of holocracy. Though leadership has long since shifted to a more hierarchical structure, vestiges of holocracy lurk in unexpected places. One such remnant is iOS tactical, a (bi)weekly gathering of iOS engineers (for more details, jump to “What’s in a tactical?”). Despite its arcane origins, tactical is by no means obsolete: it remains instrumental to building…

A long-lasting, stable solid-state lithium battery

Credit: CC0 Public Domain Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today’s lithium-ion batteries fall short of what’s needed—they’re too heavy, too expensive and take too long to charge. For decades, researchers have tried to harness the potential of solid-state, lithium-metal batteries, which hold substantially more energy in the same volume and charge in a fraction of the time compared to traditional lithium-ion batteries. “A lithium-metal battery is considered the holy grail for…

Eco-friendly device detects real-time pipe damage

Dr Sarah Guerin, a postdoctoral researcher at the Department of Physics and the Bernal Institute in UL Credit: Sean Curtin/True Media A researcher at University of Limerick has developed a low-cost, environmentally friendly sensor that can detect damage in pipelines and could save water as a result. The damage detection sensor uses highly sensitive, eco-friendly crystals that generate an electrical signal in response to a leak. It is the first validation of these biological crystals for real world applications, according…

Highly available and highly scalable Cloudflare tunnels

Starting today, we’re thrilled to announce you can run the same tunnel from multiple instances of cloudflared simultaneously. This enables graceful restarts, elastic auto-scaling, easier Kubernetes integration, and more reliable tunnels. What is Cloudflare Tunnel? I work on Cloudflare Tunnel, a product our customers use to connect their services and private networks to Cloudflare without poking holes in their firewall. Tunnel connections are managed by cloudflared, a tool that runs in your environment and connects your services to the Internet…

Meet Ronald McGarvey – University of Missouri College of Engineering

Engineers develop tools to solve big problems such as food production, pollution and pandemics. But it also takes engineering expertise to best use these tools to accomplish goals efficiently. Meet Ron McGarvey, an operations research expert with a mathematical mind and a head for public policy. McGarvey is an associate professor in Industrial and Manufacturing Systems Engineering with a joint appointment in the Truman School of Government and Public Affairs. He’s co-director in the Center for Excellence in Logistics and…

Using machine learning and radar to detect drones in complicated urban settings

Researchers work to train an AI algorithm what birds look like to radar in the Duke Gardens. Credit: Duke University Look, up in the sky! It’s a bird! It’s a plane! It’s…actually pretty easy for radar to tell the difference. Flying aliens from Krypton notwithstanding, there are simply not many things moving through the mostly empty, wide-open skies that are as big and fast as an airplane. But if radar signals move down from the clouds and into a city’s…

Theoretical method can make objects invisible to a thermal camera, or mimic a different object — ScienceDaily

Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter. In a paper published in Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, an international group of applied mathematicians and physicists, including Fernando Guevara Vasquez and Trent DeGiovanni from the University of…

How fasting diets could harm future generations — ScienceDaily

Fasting diets could impact the health of future generations according to new research from the University of East Anglia (UEA). Fasting diets have risen in popularity in recent years, however little is known about the long-term impact of these diets, particularly for future generations. New research, published today in the journal Proceedings of the Royal Society B, reveals that reduced food intake in roundworms (Caenorhabditis elegans) has a detrimental effect on three generations of offspring — particularly when those descendants…

Spotify Wins CNCF’s Top End User Award and Toots Own Horn About It : Spotify Engineering

May 11, 2021 Published by Dave Zolotusky, Principal Engineer & CNCF Technical Oversight Committee Representative Last week, Spotify won an award — and we’re not playing it cool. We tweeted. We bragged on LinkedIn. Our internal Slack is alive with emoji and exclamation points. We’re really very proud of this one. The award is Cloud Native Computing Foundation’s Top End User Award, announced at last week’s KubeCon + CloudNativeCon. Voted on by the 140+ organizations in…
