A preprint led by Lisa Matthias at Humboldt University of Berlin tracked 440 academic journals that began as diamond open-access, meaning free for both authors and readers, but later shifted to charging fees between 2009 and 2026. Most of these titles, 369, moved to gold open access with article-processing charges, 52 adopted hybrid models, and 19 became fully paywalled, with fees ranging from $8 to $5,300 depending on publisher type.
Ars Technica revisited the 2026 Hyundai Ioniq 5, testing an AWD Limited trim with an 84 kWh battery, NACS charging port, and 320 hp output following the car's early 2025 refresh. The reviewer found the retro styling and fast-charging capability still hold up well five years after launch, though the AWD version's range drops to 269 miles compared to 318 miles for the rear-wheel-drive model.
A guide breaks down what's required to run an RV fully on solar power, noting that most users still pair solar with a backup generator rather than going all-solar. Going fully solar demands a battery bank to store energy, an inverter to convert DC to AC, and a charge controller to regulate power flow from panels to storage.
Researchers report that water droplets carrying electric charge erode surfaces more aggressively than neutral droplets upon impact. The finding, published via Nature.com, points to charge as an overlooked factor in droplet-driven erosion processes.
The Supreme Court ruled on September 4 that broadcast TV stations must sell election ads to political parties and joint fundraising committees at the same lowest unit charge rates required for individual candidates. The order came after the National Republican Congressional and Senatorial Committees petitioned the court, overturning a Fourth Circuit ruling that had sided with Democratic candidates who challenged an FCC notice mandating the discount.
Xbox controllers can be powered by more than disposable AA batteries, with Microsoft's official Play and Charge Kit swapping them for a $24.99 lithium-ion pack that charges via USB-C and lasts up to 30 hours. Third-party options include swappable dual-battery docks and rechargeable AA batteries, while players can also simply keep their controller plugged in during play for continuous power.
Nokia and HMD Global released the 300 Charge, a blocky retro-style feature phone priced around $32 with a powerbank function, SD card slot, headphone jack and bright LED flashlight. The device is currently sold only in the Philippines, with no announced release date for the US or other markets.
After the 4th Circuit Court of Appeals struck down an FCC order that extended discounted 'lowest unit charge' TV ad rates to political parties and joint fundraising committees, the National Republican Congressional and Senatorial Committees said they will petition the Supreme Court. The 4th Circuit denied their request for an emergency stay but issued the mandate immediately, clearing the way for a Supreme Court appeal.
Nokia's new 300 Charge dumb phone packs a 3,700mAh battery capable of 37 hours of talk time, but its standout feature is a reverse-charging 'powerbank mode' that outputs 10W via a bundled 4-in-1 cable with Micro USB, USB-C and USB-A adapters. The phone also includes a bright LED flashlight, a 3.5mm headphone jack, and basic specs like a Unisoc SC6531E chipset, 4GB RAM/storage, a QVGA camera and a 2.4-inch display.
Quantinuum has introduced Helios, a 98-qubit trapped-ion quantum computer that uses a four-way junction to shuttle ions between memory and processing zones, alongside new control software called Helios runtime that schedules ion movement and laser operations. It surpasses the company's earlier machines, which had 32 qubits in 2023 and 56 qubits in 2025, making it the largest trapped-ion system built so far.
Quantinuum has unveiled Helios, a trapped-ion quantum computer using 98 qubits, the largest such system built to date. The machine relies on a new four-way X junction hardware design paired with Helios runtime software, allowing it to move and process data across multiple paths simultaneously rather than in a single line, as earlier machines required.
USB PD, especially its PPS feature, now underpins fast charging on most major phones, including Apple's iPhone 17 and Android flagships like Samsung's Galaxy S26 Ultra and Google's Pixel 11 series. Qualcomm Quick Charge, once dominant, has largely folded into USB PD compatibility, while brands like OnePlus, Oppo and Xiaomi still rely on proprietary systems such as SuperVOOC and HyperCharge for their fastest speeds.
