Perseverance gets onboard GPS-like localization for autonomous Mars driving

NASA’s Perseverance now uses an onboard system called Mars Global Localization to pin down its exact position on Mars by matching panoramic images to orbital terrain maps, achieving accuracy of about 25 centimeters. This allows the rover to navigate more autonomously and travel farther without Earth-based guidance, building on AI-driven planning and reducing reliance on ground control.

Cross-species brain science: uniting data to reveal general principles

The author argues that neuroscience, despite vast cross-species data, remains fragmented into species-specific frameworks, hindering the discovery of general brain principles. She calls for making cross-species dialogue a core organizational principle, using differences between species (such as how hippocampal theta appears across rodents and humans) to constrain and refine theory rather than treat them as anomalies. The piece also urges frameworks that link signals across scales, reforms in training and conferences, and funding and publication practices that reward cross-species theory testing rather than single-model optimization.

Bats on a Remote Island Reveal Real-World Brain Compass

Researchers tracked brain activity of Egyptian fruit bats on a remote island to understand how head-direction cells form an internal compass. Using implanted microwires and wireless recording, the team found that, as the bats learned the island, their head-direction cells stabilized to precise directions anchored to landmarks, supporting a global compass model tied to the environment rather than magnetic or celestial cues. The work highlights the value of wild, real-world studies for navigation research and suggests humans may share a similar directional system.
