Dell Technologies surveyed more than 15,000 members of the Generation Z (Gen Z) cohort across 15 countries to find they have little faith in governments or educational systems to provide a better future. About 50% of respondents are willing to accept short-term economic hardship if policymakers can commit to long-term solutions, yet just one-third of those surveyed think current government investments will support a thriving digital economy. Meanwhile, less than half (44%) said school only gave them basic computing skills, with 37% saying it did not equip them with the technology skills they required for their planned careers.

January 25, 2023


A Consumer Reports study found an increase in the use of memory safe programming languages in the last two years. The report said more projects, including those from Meta, Google's Android Open Source Project, and the Linux kernel, are adopting Rust for codebases written in C and C++ to make code more memory safe. The report said computer science professors could boost the weight of memory safety mistakes in assessing grades. Among other things, the report recommends developers list memory safety mitigations for a piece of software and provide a "nutrition label" of sorts that details the percentage of code covered by safe languages, audits, fuzzing, sandboxing, and least privilege, among other things.

Researchers at the Massachusetts Institute of Technology, Columbia University, and the University of Wisconsin-Madison have formulated the "c-value" measure to help scientists choose which estimation methods to apply when modeling specific data problems. C-value helps users decide between approaches based on the odds that a new method will yield greater accuracy for a particular dataset. The c-value equation employs the dataset to first compute the estimate with each technique, then to compute the c-value between techniques. Methods with a high c-value are unlikely to be less accurate than the original method on the data problem. The researchers assessed c-value using real-world data problems, including modeling ocean currents, calculating violent crime in neighborhoods, and approximating students' reading skills in school.

During the 24 Hours of Le Mans Virtual competition on Jan. 14-15, a sudden disconnection from the server resulted in two-time Formula One champion Max Verstappen's team dropping from first to 15th place. Verstappen immediately retired from the competition, which had been plagued by multiple technical issues, including random disconnects and distributed denial-of-service attacks. Such problems come as sim racing is gaining popularity as a pipeline for aspiring real-world racecar drivers. According to Cam Royal of Veloce, a team that competes in both real-life and virtual racing, motorsports scouts often watch sim races to identify emerging talent. “We look at driving habits and consistency,” said Royal.

Researchers in Korea developed a quadrupedal robot that can walk even in deformable terrain such as a sandy beach. Robo-Dog 'RaiBo' Runs Through Sandy Beach
KAIST (South Korea)
January 26, 2023


Scientists at South Korea's Korea Advanced Institute of Science & Technology (KAIST) have developed a four-legged robot dog that can agilely traverse sandy beaches. The team simulated the force acting on the robot from granular ground and designed an artificial neural network controller that makes real-time decisions to adapt to variable terrain without prior information while walking. Calculating the force produced from one or more contacts at each time step efficiently models the deformable terrain, while the recurrent neural network architecture predicts terrain properties by analyzing time-series sensory data. After researchers mounted the learning-based controller on the "RaiBo" robot, it ran on a beach at a top speed of 3.03 meters (nearly 10 feet) per second.

A research team at Singapore's Nanyang Technological University (NTU) created an artificial skin that can sense the presence of nearby objects without coming into physical contact with them. The skin features two nickel-coated conductive fabric layers surrounding a sponge bathed in ionic liquid, which functions as an electrical conduit. The electrode layers form a capacitor that quantifies changes in distance between them in order to detect physical contacts with objects. The skin relies on machine learning techniques to identify how an object it detects compares with data on known materials. In tests, the skin successfully classified a series of objects brought near it as being either polymer, metal, or skin.

A machine vision system developed by researchers at Pennsylvania State (Penn State) and Washington State universities can locate apple king flowers in blossom clusters on trees. Penn State's Xinyang Mu used the Mask R-CNN deep learning algorithm to identify and locate king flowers by conducting pixel-level segmentation to detect partly obscured objects. Mu recorded hundreds of apple blossom cluster photos, then devised a king flower segmentation algorithm to extract the flowers from the dataset. The system's accuracy varied from 98.7% to 65.6% compared to identification by eye. Penn State's Long He said, "We think this result will provide baseline information for a robotic pollination system, which would lead to efficient and reproducible pollination of apples to maximize the yield of high-quality fruits."

An international team led by researchers at the U.K.'s University of Cambridge demonstrated that a lattice-matched semiconductor material system can improve quantum storage time. Until now, optically active semiconductor quantum dots had a storage time of just a few microseconds at most. The researchers were able to achieve a nearly two-order magnitude improvement in storage time using their material system. Cambridge's Claire Le Gall said, "For spins in quantum dots, short coherence times were the biggest roadblock to applications, and this finding offers a clear and simple solution to that."

The Galilee Medical Center in Nahariya, Israel, has opened a "smart room" for the management of inventory in operating rooms through a partnership between Florida-based automation provider Autonomi and Israeli group purchasing organization Sarel. The smart room can track items assigned to the medical team and medical cases without requiring assistance from end users. It also monitors inventory usage for each procedure; prevents depletion of supplies through automated reorders; performs real-time patient-safety recalls, and posts warnings of upcoming expiration dates. The hospital said the room will help optimize the performance of the medical team while reducing the costs of equipment and drugs by up to 15% annually.

Computer science researchers from Germany's Johannes Gutenberg University and the U.K.'s University College London found the ChatGPT chatbot can detect and correct buggy code better than existing programs. The researchers gave 40 pieces of bug-embedded software to ChatGPT, and to three other code-fixing systems for comparison. ChatGPT's performance on the first pass was similar to that of the other systems, but the ability to dialogue with the bot after receiving the initial answer ultimately helped it overtake the others. The researchers explained, "We see that for most of our requests, ChatGPT asks for more information about the problem and the bug. By providing such hints to ChatGPT, its success rate can be further increased, fixing 31 out of 40 bugs, outperforming state-of-the-art."

Technologies like robot pets and virtual reality (VR) platforms could alleviate social isolation among older adults, yet sustainable adoption has proven challenging. Rendever provides VR to long-term care communities, with experiences like meet-ups with avatars of loved ones in virtual homes. Drawbacks, however, include a non-intuitive software setup. Tombot is developing a robotic Labrador retriever puppy due out late next year that is intended to offer people with mild cognitive impairment the companionship of a pet without the upkeep of a real animal. “We saw older adults adopt virtual engagement at a much faster pace than we thought during the pandemic because there was no other choice,” said the National Council on Aging's Dianne Stone.
