Submarines are designed to hide, so what happens if one is missing?

Credit: Pixabay/CC0 Public Domain In waters north of Bali, a frantic search is underway for the Indonesian submarine KRI Nanggala, missing with 53 crew since the boat failed to make a routine signal report on Wednesday morning. How to hunt a submarine There are two key challenges when a submarine goes missing. The first is finding it. A submarine is inherently covert. When the Nanggala dived as part of a routine exercise, it is unlikely the boat was being tracked.…

Ankle exoskeleton enables faster walking — ScienceDaily

Being unable to walk quickly can be frustrating and problematic, but it is a common issue, especially as people age. Noting the pervasiveness of slower-than-desired walking, engineers at Stanford University have tested how well a prototype exoskeleton system they have developed — which attaches around the shin and into a running shoe — increased the self-selected walking speed of people in an experimental setting. The exoskeleton is externally powered by motors and controlled by an algorithm. When the researchers optimized…

ANYbotics reveals full-scale robotic inspection solution

Credit: ANYbotics The Swiss robotics company ANYbotics has announced the launch of a new end-to-end robotic inspection system for the energy and industrial processing arenas. This solution aims to answer the call for better safety at production sites and lower downtime. However, as technology has rarely kept pace with increasing safety and production demands, ANYbotics’ full autonomous, quadruped robot ANYmal uses inspection analytics software to automate routine condition monitoring of all infrastructure and equipment. So far, the company has introduced…

The first US population to experience drone delivery gives it a seal of approval

The drone-delivery service in Christiansburg, Va.—the first in the country to deliver goods directly to residences on demand—gave researchers a unique opportunity to study how people feel about the technology when they’ve actually experienced it in their own community. Credit: Virginia Tech The week of Thanksgiving last year, a postcard arrived in mailboxes in Christiansburg. A link to a survey was on the back. On the front, there was a picture that was, by then, very familiar to the residents…

Undergraduate Honors Research Fellowship Project ‘Fantastic Fit’ for IT Student

For Andrew Murphy, receiving an Undergraduate Honors Research Fellowship from Mizzou Engineering was an ideal way to finish out his senior year. The fellowship, which comes with a stipend, is designed to get undergraduates involved in engineering research. Murphy worked with Assistant Teaching Professor Fang Wang to develop a web portal and companion mobile app. “It was just a fantastic fit,” he said. “I’d definitely recommend other students apply for the fellowship. It’s a great opportunity to get experience, help…

‘Fingerprint’ for 3D printer accurate 92% of time

University at Buffalo tech can identify machines by their unique ‘hot end,’ could aid intellectual property, security. Credit: University at Buffalo 3D printing is transforming everything from fashion and health care to transportation and toys. But this rapidly evolving technology, also known as additive manufacturing, can threaten national security and intellectual property rights. To reduce illicit use of 3D printers, Zhanpeng Jin, Ph.D., associate professor in the Department of Computer Science and Engineering at the University at Buffalo, is developing…

Infection induces antibodies capable of killing infected cells regardless of disease severity — ScienceDaily

Drawing on epidemiological field studies and the FrenchCOVID hospital cohort coordinated by Inserm, teams from the Institut Pasteur, the CNRS and the Vaccine Research Institute (VRI, Inserm/University Paris-Est Créteil) studied the antibodies induced in individuals with asymptomatic or symptomatic SARS-CoV-2 infection. The scientists demonstrated that infection induces polyfunctional antibodies. Beyond neutralization, these antibodies can activate NK (natural killer) cells or the complement system, leading to the destruction of infected cells. Antibody levels are slightly lower in asymptomatic as opposed to…

Next-generation inflatable buildings maintain their shape without constant input of pressure

This inflatable shelter is out of thick plastic sheets and can pop up or fold flat. Credit: Benjamin Gorissen/David Melancon/Harvard SEAS In 2016, an inflatable arch wreaked havoc at the Tour de France bicycle race when it deflated and collapsed on a cyclist, throwing him from his bike and delaying the race while officials scrambled to clear the debris from the road. Officials blamed a passing spectator’s wayward belt buckle for the arch’s collapse, but the real culprit was physics.…

Announcing Cloudflare Images beta to simplify your image pipeline

Today, we are announcing the beta of Cloudflare Images: a simple service to store, resize, optimize, and deliver images at scale. In 2018, we launched Stream to provide a single product that could be used to store, encode, and deliver videos. With Cloudflare Images, we are doing for images what Stream did for videos. Just like Stream, Cloudflare Images eliminates the need to think about storage buckets, egress costs, and many other common problems that are solved for you out…
