Nature Communications, Published online: 22 June 2026; doi:10.1038/s41467-026-74794-3 Dynamic control of surface textures is limited by static or coarse-patterned approaches, restricting their application in programmable object manipulation and information encoding. This study achieved reversible, spatiotemporally programmable surface wrinkling on a photothermal liquid crystal elastomer bilayer, …

The Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu) announced that a research team led by Dr. Hanmin Lee, head of the Department of Industrial Machinery DX under KIMM's Virtual Engineering Platform Research Division, has developed fundamental technologies for four key components of next-generation rotorcraft power transmission systems: clutches, gears, housings and bea…

I am a research scholar working on a scintillation detector coupled with a SiPM for radiation/cosmic muon measurements. I am using a MicroFJ-60035 SiPM Silicon Photomultipliers (SiPM), High PDE and ...

Constructing deep underground tunnels faces severe challenges when the surrounding rock contains weak, unstable layers. This study investigates how the angle and spacing of these weak layers lead to the deformation and collapse of deep tunnel structures. A particle flow simulation, based on a 1,000–m-deep tunnel, was developed to recreate the physical behavior of the surrounding rock and observe …

TL;DR A cluster of discarded smartphones can match the cost and performance profile of cloud server instances for a defined, bounded class of workloads bursty, latency-tolerant, horizontally-scalable services like microservices, dev environments, and educational platforms. This isn't a sustainability thought experiment. A 2023 prototype (10 Pixel 3A phones) ran real end-to-end microservice benchm…

nvidia-peermem "Invalid argument" on Ubuntu — Fix GPUDirect RDMA with DMA-BUF TL;DR: If modprobe nvidia-peermem fails with Invalid argument ( -EINVAL ) on a system using the inbox Ubuntu InfiniBand stack ( rdma-core ), the module is not broken and you do not need it. nvidia-peermem requires an API that only exists in MLNX_OFED. On Hopper/Blackwell GPUs with the NVIDIA open driver, use DMA-BUF ins…

To celebrate the beginning of summer, we take a behind-the-scenes look at how a water slide works using Simcenter Flomaster.

Smaller, cheaper cars built for narrow city streets are becoming more stylish – but require careful design decisions The winding backstreets of London, Paris and Rome are a large part of their charm. But they are also a problem for electric carmakers. For a long time, squeezing big batteries into smaller, cheaper cars to fit European streets was too much of a problem, so manufacturers focused on …

I've wanted easy trunk-based development for Salesforce for years. Short-lived branches, frequent merges, small pull requests, and CI fast enough that developers aren't afraid to commit. The same practices that engineering teams use everywhere else. Every time I tried to make it work, I hit the same wall: Apex tests require an org. That single dependency turns every validation run into an infrast…

Researchers at the Medical University of Vienna, in collaboration with ETH Zurich, the Technical University of Munich and Medical Faculty Belgrade, have developed a wearable neurorobotic system that combines electrical neurostimulation with hand exoskeletons. In a clinical trial involving 14 patients with hand impairments caused by neurological injury, the technology supported finger mobility, ta…

Researchers have uncovered a critical mechanism behind battery failure in solid-state batteries, offering new insights that could help unlock safer, longer-lasting energy storage technologies. Every time a smartphone is charged or an electric vehicle is plugged in, billions of lithium ions move through a battery to store energy. Future devices could perform far better with [...]

Hey Dev.to community! 👋 I wanted to take a moment to introduce myself and share the journey behind the company I founded. My name is Aiden McElroy, and I am the CEO and Founder of Al's-Ops LLC. If you love DevOps, automation, and building scalable infrastructure, you're in the right place. The Vision Behind Al's-Ops Every developer knows the pain of repetitive tasks, fragile deployment pipelines,…

A discussion of how to successfully leverage agentic AI to raise the productivity ceiling covering the topics of human oversight, governance, and disciplined engineering practices that preserve stability.

The material I am hoping to discuss and find answers to is based around the future-proofing of ocean voyages using both solar and hydrogen as power sources. I have a concept I will be laying out on paper over the next 12 months of a Trimaran with two electric motors which, if I can solve the one... Read more

As NASA pushes to build a sustained human presence on the moon, one expert says what's needed is a lunar building code.

Researchers have demonstrated they can make coffee comparable to conventional espresso using ultrasonic waves. Because the process doesn’t need hot water, it consumes 75 percent less energy.
