What happens in the brain when it learns something new

Memories of significant learning experiences—like the first time a driver gets a speeding ticket—are sharp, compared to the recollection of everyday events—like what someone ate for dinner two weeks ago. That’s because the human brain is primed to learn from helpful associations.

Carnegie Mellon University researchers have identified specific neural connections that are especially sensitive to this process of learning about causality. The discovery, while seemingly intuitive, could have widespread implications for understanding how humans learn and inform new ways to address learning challenges.

“If you look out the window and see dark clouds, you know that it’s going to rain and that you’ll need an umbrella,” said Eunsol Park, a Ph.D. student in the Department of Biological Sciences and the Center for the Neural Basis of Cognition, a joint program between Carnegie Mellon and the University of Pittsburgh.

Advanced computer modeling predicts molecular-qubit performance

A qubit is the delicate, information-processing heart of a quantum device. In the coming decades, advances in quantum information are expected to give us computers with new, powerful capabilities and detectors that can pick up atomic-scale signals in medicine, navigation and more. The realization of such technologies depends on having reliable, long-lasting qubits.

Now, researchers have taken an important step in understanding the rules necessary for the design of useful, efficient qubits.

Using advanced computer modeling, the researchers came up with a way to accurately predict and fine-tune key magnetic properties of a type of device called a molecular qubit. They also figured out which factors in the material that the qubit sits in affect this tuning the most and calculated how long the qubits can live.

How to Create a Data Analyst Agent

This video shows you how to create a data analyst AI agent using Llama Nemotron Super 1.5 49B, a NAS-optimized, open-weight reasoning model. It tops the Artificial Analysis Intelligence Index in the ~70B range—while fitting on a single NVIDIA H100 or NVIDIA H200 GPU for higher throughput and lower cost.

Folding spacecraft design could be enhanced with origami patterns

Folding spacecraft design could be enhanced with Japan’s ancient origami patterns.


Scientists are exploring a new class of origami structures that could help design and build different shapes for use in space. These structures are expected to be even more compact and reliable.

Called bloom patterns, the new class of origami structures developed at Brigham Young University fold up flat and unfold like flower petals. Researchers expect such designs could be used in telescopes and solar arrays as well.

These structures are suitable for use in spacecraft as origami-based designs could help fold up for launch and then unfold or deploy to their full size when required in space.

AI system slashes GPS errors almost 40 times in urban settings

End of the road for GPS? Image-based AI tool cuts navigation errors by nearly 40 times.


Global reliance on GPS has grown to the point where outages or signal interference can have serious consequences. From logistics and delivery fleets to aviation and defense, industries depend on precise navigation.

Yet GPS signals are vulnerable. Tall buildings, tunnels, jamming devices, or even atmospheric conditions can cause disruptions. By providing a GPS-free alternative, PEnG could make navigation more resilient and reliable.

The Surrey researchers argue that their work is as much about everyday convenience as it is about safety.
