For most people, a set of nickel-metal hydride (NiMH) rechargeable batteries is the way to go. Panasonic Eneloop is an Engadget staff favorite. It's consistent and tends to hold up over time better than cheaper options. If you want to save a few bucks, IKEA LADDA is a good budget alternative. Both are sold in the AA and AAA sizes you need for these systems.

Charging to 100% stresses your battery, as most cap at 80%. Not a week goes by that I'm not correcting someone who is still recycling some battery myth packaged as a tip from the nickel-cadmium era (also known as the 1990s). These tips have been repeated and regurgitated so many times. A quick Google search (or an AI prompt) turns up plenty of articles that reassure readers that the tips are 100% grounded in present-day, lithium-ion era reality, when they most definitely are not.

I put handheld, wearable, and misting fans through a sweltering summer to see which ones kept me coolest. When I was first hired as a commerce editor at WIRED in summer 2024, one of the first media requests I fielded was from a nationally renowned talk show. The ask was for an editor to speak on the popularity of portable and neck fans. High-temperature records were breaking all over the US, and abroad, neck fans were suddenly the "it" accessory at the Paris Olympics, hugging the nape of athletes like Simone Biles. "I can't do this," I told my manager at the time.

Solid-state batteries are safer and more capable--but harder to mass-produce. They also represent an opportunity for non-Chinese companies to get back in the game. The field of lithium batteries is currently dominated by Chinese companies like BYD and CATL. Not only do they sell the majority of batteries that go into electric vehicles and energy storage projects worldwide, they're also opening up new factories in your backyard . When companies outside China try to compete, like Europe's Northvolt, they quickly realize how hard it is .

PCWorld's battery testing reveals AMD's Ryzen AI 7 445 processor delivers disappointing battery life performance in laptops like the Acer Swift Go 14 AI. The chip ranked last in streaming tests and efficiency scores, falling behind Qualcomm's Snapdragon X Elite and Intel's Core Ultra processors. With Ryzen AI 400 processors appearing in about a third of productivity laptops, users may want to consider Intel or Qualcomm alternatives for better battery performance. AMD's Ryzen mobile processors appear in about a third of all productivity laptops sold today. So, how does the Ryzen AI 400, AMD's latest mobile processor, actually hold up in real-world battery tests?

Accurate prediction of ionic conductivity in electrolyte systems is crucial for advancing numerous scientific and technological applications. While significant progress has been made, current research faces two fundamental challenges: (1) the lack of high-quality standardized benchmarks, and (2) inadequate modeling of geometric structure and intermolecular interactions in mixture systems. To address these limitations, we first reorganize and enhance the CALiSol and DiffMix electrolyte datasets by incorporating geometric graph representations of molecules. We then propose GeoMix, a novel geometry-aware framework that preserves Set-SE(3) equivariance--an essential but challenging property for mixture systems. At the heart of GeoMix lies the Geometric Interaction Network (GIN), an equivariant module specifically designed for intermolecular geometric message passing. Comprehensive experiments demonstrate that GeoMix consistently outperforms diverse baselines (including MLPs, GNNs, and geometric GNNs) across both datasets, validating the importance of cross-molecular geometric interactions and equivariant message passing for accurate property prediction. This work not only establishes new benchmarks for electrolyte research but also provides a general geometric learning framework that advances modeling of mixture systems in energy materials, pharmaceutical development, and beyond.

Generative diffusion models have achieved remarkable success in producing high-quality images. However, these models typically operate in continuous intensity spaces, diffusing independently across pixels and color channels. As a result, they are fundamentally ill-suited for applications involving inherently discrete quantities such as particle counts or material units, that are constrained by strict conservation laws like mass conservation, limiting their applicability in scientific workflows. To address this limitation, we propose Discrete Spatial Diffusion (DSD), a framework based on a continuous-time, discrete-state jump stochastic process that operates directly in discrete spatial domains while strictly preserving particle counts in both forward and reverse diffusion processes. By using spatial diffusion to achieve particle conservation, we introduce stochasticity naturally through a discrete formulation. We demonstrate the expressive flexibility of DSD by performing image synthesis, class conditioning, and image inpainting across standard image benchmarks, while exactly conditioning total image intensity. We validate DSD on two challenging scientific applications: porous rock microstructures and lithium-ion battery electrodes, demonstrating its ability to generate structurally realistic samples under strict mass conservation constraints, with quantitative evaluation using state-of-the-art metrics for transport and electrochemical performance.

According to marine biologists, you'll likely have to settle with admiring it from afar for now unless you have access to a deep sea submersible--and a ticket to the Galápagos Islands . While conducting a deep sea expedition aboard the research vessel E/V, biologists spotted the diminutive invertebrate as they piloted a remotely operated vehicle (ROV) along the ocean floor near Darwin Island.
