Kirigami is a traditional Japanese art form that entails cutting and folding paper to produce complex three-dimensional (3D) structures or objects. Over the past decades, this creative practice has also been applied in the context of physics, engineering, and materials science research to create new materials, devices and even robotic systems.

Researchers at Sichuan University and McGill University recently devised a new approach for the inverse engineering of kirigami, which does not rely on advanced computational tools and numerical algorithms. This new method, outlined in a paper published in Physical Review Letters, could simplify the design of intricate kirigami for a wide range of real-world applications.

“This work is a natural extension of our previous work on kirigami,” Damiano Pasini, senior corresponding author of the paper, told Phys.org.

Putting hypersensitive quantum sensors in a living cell is a promising path for tracking cell growth and diagnosing diseases—even cancers—in their early stages.

Many of the best, most powerful quantum sensors can be created in small bits of diamond, but that leads to a separate issue: It’s hard to stick a diamond in a cell and get it to work.

“All kinds of those processes that you really need to probe on a , you cannot use something very big. You have to go inside the cell. For that, we need nanoparticles,” said University of Chicago Pritzker School of Molecular Engineering Ph.D. candidate Uri Zvi. “People have used diamond nanocrystals as biosensors before, but they discovered that they perform worse than what we would expect. Significantly worse.”

Ultrasound is more tissue-friendly and less absorbed by the body, making it a reliable option for powering implantable and skin-adherent devices. As a result, ultrasonic energy is emerging as a next-generation solution for wireless charging.

A flexible, biocompatible solution

A research team led by Dr. Sunghoon Hur from the Electronic and Hybrid Materials Research Center at the Korea Institute of Science and Technology (KIST), along with Professor Hyun-Cheol Song of Korea University, has developed a biocompatible ultrasonic receiver that maintains consistent performance even when bent.

Slight variations in a person’s pulse rate could give clues about the likelihood of future cognitive decline, according to a new study, potentially giving us a valuable new test for cognitive problems that would be quick and easy to run.

This is something that researchers invest a lot of time in, because knowing when cognitive decline might start, and how it may progress, means better support and more clarity for those involved. Along the way, it also reveals new insights into how these conditions develop, and how they might be stopped for good.

In this study, an international team analyzed pulse rate data across a night of sleep from 503 individuals with an average age of 82. Cognitive tests were also carried out around that same time, as well as in at least one follow-up visit.

HELSINKI — Chinese commercial satellite manufacturer MinoSpace has won a major contract to build a remote sensing satellite constellation for Sichuan Province, under a project approved by the country’s top economic planner.

Beijing-based MinoSpace won the bid for the construction of a “space satellite constellation,” the National Public Resources Trading Platform (Sichuan Province) announced May 18, Chinese language Economic Observer reported.

The contract is worth 804 million yuan (around $111 million) and the constellation has been approved by the National Development and Reform Commission (NDRC), China’s top economic planning agency, signaling potential alignment with national satellite internet and remote sensing infrastructure goals.

As many as 60 malicious npm packages have been discovered in the package registry with malicious functionality to harvest hostnames, IP addresses, DNS servers, and user directories to a Discord-controlled endpoint.

The packages, published under three different accounts, come with an install‑time script that’s triggered during npm install, Socket security researcher Kirill Boychenko said in a report published last week. The libraries have been collectively downloaded over 3,000 times.

“The script targets Windows, macOS, or Linux systems, and includes basic sandbox‑evasion checks, making every infected workstation or continuous‑integration node a potential source of valuable reconnaissance,” the software supply chain security firm said.
