A 150-million-parameter AI solved 29.5% of ARC-AGI-1 tasks at a cost of $0.00070 each. Instead of producing a written chain of thought, it updates an internal memory and reasons in an internal workspace before giving an answer.

Digital twin brains hinge less on computing power than on how much of a living brain can be measured, constrained and updated over time. With about 86 billion neurons, human brains remain far beyond full synaptic-level mapping, so any feasible twin would need to keep pace with change.

Four hybrid gasoline blends reached 95 to 102 octane by adding isopropanol and MED to conventional fuel components. In laboratory tests, they outperformed the base gasoline in knock resistance and met local standards, but large-scale cost and life-cycle performance remain unresolved.

Twisted 3D microchannels have been fabricated continuously inside polymer fibers, offering a scalable route to efficient micromixers. The channels were formed with high precision, and twist-plus-helix designs boosted mixing across a wide range of flow rates.

A safer oxyfluoride solid electrolyte reached 16.3 mS/cm at room temperature, the highest reported bulk lithium-ion conductivity among oxide-related solid electrolytes. Its fluoride ions appear to shift slightly as lithium ions hop, lowering the barrier to movement.

A 3D-printed electrode with a “diamond” geometry increased redox flow battery performance by 52%. The design improves how liquid moves through the battery, and the water-based system could offer a safer option for storing renewable energy at large scale.

Don't miss a beat! Here are yesterday's top stories: Robots are edging closer to animal-like agility and human-friendly touch, from a four-legged machine that learns to squeeze and leap through tight gaps to a soft printed hand that can handle both eggs and heavier everyday objects. Alongside that physical dexterity, precision is showing up in less visible ways: sound directed to a single listener, cleaner carbon capture at sea, and a transistor design that hints at new routes around long-standing chipmaking limits.

A drone now perches more like a bird: it feels for a branch, learns its position and orientation through touch, aligns its three-fingered hand, and grips tightly enough to switch off its motors when vision is blocked.

In 12-centimeter channels, California blackworms took nearly three times as long to escape wider paths as narrower ones. Extra space let them pause, bend and reorient more often instead of heading straight for the exit.

An ocean CO₂ capture prototype removed 86% of mineral buildup between cycles with no acid wash or downtime, helping keep energy intensity steady while extracting dissolved carbon dioxide from seawater.
