Decoding Protein Motion with Digital Building Blocks

November 15, 2025 by BBG News

Protein structures are discretized into a vocabulary of “Structure Tokens” by a Vector Quantized Variational Autoencoder, enabling an autoregressive language model to predict structural sequences conditioned on the underlying amino acid sequence, thereby framing protein structure prediction as a discrete sequence modeling problem.

A new approach leverages discrete representations of protein structure to efficiently generate diverse and realistic conformational ensembles, offering a fresh perspective on modeling protein dynamics.

Unlocking Robotic Precision: Machine Learning Discovers the Laws of Friction

November 15, 2025 by BBG News

A systematic refinement process—beginning with robotic data acquisition and iterative model fitting using a Kernelized Artificially-constrained Network (KAN)—culminates in a parsimonious friction model derived through pruning, symbolic regression, and subsequent refinement, effectively distilling complex physical behavior into a concise, analytically tractable form.

A new approach leverages the power of artificial intelligence to automatically derive accurate and understandable models of static friction for robotic systems.

PuffyBot: A Robot That Walks, Swims, and Floats

November 15, 2025 by BBG News

The robot transitions seamlessly between underwater states—from resting on the seabed at $0$ seconds, to initiating body expansion and lift-off by $5$ seconds, achieving positive buoyancy and ascent at $45$ seconds, and finally surfacing completely at $46$ seconds—demonstrating shape-morphing driven buoyancy control.

Researchers have developed an untethered, shape-morphing robot capable of seamlessly transitioning between land, underwater, and surface locomotion with improved energy efficiency.

Falling with Style: Robots Learn to Tumble Gracefully

November 15, 2025 by BBG News

A reinforcement learning policy cultivates robust self-protective behaviors in response to impending falls, balancing the imperative to achieve a user-defined end pose with the minimization of impact forces—a delicate negotiation informed by explicitly modeled sensitivities of the robot’s constituent parts.

Researchers have developed a reinforcement learning system that allows bipedal robots to execute controlled falls, prioritizing both safety and aesthetic pose achievement.

Decoding Stellar Chemistry with Deep Learning

November 15, 2025 by BBG News

The distributions of carbon and alpha element abundances relative to iron—critical indicators of stellar origins and evolution—reveal a systematic difference between observed halo stars from the APOGEE survey and the simulated dataset, particularly at low metallicities where the survey’s reach is limited, highlighting the boundaries of current observational constraints on models of galactic chemical evolution.

A new unsupervised approach uses artificial intelligence to analyze stellar spectra and reveal the chemical composition of stars without relying on pre-labeled data.
