Google turns I/O into an agent platform pitch

Google’s I/O recap puts Gemini 3.5 Flash, Antigravity, the Gemini API, AI Studio and Android Studio into one developer story: fast frontier models that can plan, build and iterate across longer software tasks. For teams using AI in production workflows, the signal is less about one model launch and more about platform gravity.

Cursor makes automations a multi-repo agent workflow

Cursor’s latest changelog turns its agent feature into more of a recurring-work system: automations can now be managed beside agents, reason across multiple repos, or run without a repo using marketplace templates for Slack digests, product FAQs, finance reporting and customer health checks.

NASA tests self-supervised AI for tracking harmful algal blooms

The system was trained on 2018 and 2019 satellite data, then checked against later observations and field measurements in Florida and Southern California.

A wearable knee robot improved strength in six children with SMA

The children completed 30 robot-assisted sessions over six weeks. Researchers reported larger quadriceps, stronger knees and better sit-to-stand performance, while outside experts cautioned that the study does not yet prove the robot beats other intensive rehabilitation.

The Moon and Venus over Washington

The Moon and Venus sit in conjunction above the Washington Monument on May 18, as seen from NASA’s Mary W. Jackson Headquarters building. It is a simple image, but a useful one for a daily paper: the sort of alignment that turns orbital mechanics into something visible before breakfast. Venus is bright because its cloud tops reflect sunlight efficiently; the Moon is familiar enough that its presence makes the geometry legible. Nothing rare has to be happening for the sky to become instructive. Sometimes the solar system only needs a monument, a clear line of sight and a photographer paying attention.

JAXA launches IKAROS, the first solar-sail spacecraft

On May 21, 2010, JAXA launched IKAROS with the Venus Climate Orbiter Akatsuki aboard an H-IIA rocket. IKAROS — the Interplanetary Kite-craft Accelerated by Radiation Of the Sun — was built to prove that a spacecraft could use a large membrane both to gather sunlight for power and to gain propulsion from solar radiation pressure. The idea is old and elegant: trade propellant for patience, and let photons do a small amount of work continuously. IKAROS made solar sailing a flown technology rather than a diagram, helping keep alive a form of propulsion suited to missions where endurance matters more than thrust.

Platonic Representations in the Human Brain: Unsupervised Recovery of Universal Geometry

Pablo Marcos-Manchón, Rishi Jha, Lluís Fuentemilla

This q-bio.NC preprint asks whether the ‘Platonic representation’ idea from machine learning has an analogue in human brains. Using fMRI data from the Natural Scenes Dataset, the authors train subject-specific embeddings from repeated stimulus presentations, then show that independently learned spaces can be aligned across people with unsupervised orthogonal rotations. The claim is not that brains are identical, but that visual-cortex representations may be approximately isometric: different subjects’ neural spaces can be translated through geometry alone. Treat it cautiously as a preprint, but it is a neat bridge between representation learning and neuroscience.
