If you take a walk along the coast, near Caleta Camarones in northern Chile, near an old archeological site called Camarones 15, it is hard not to spot evidence of the mummies.
Cloth, rope, hair, tiny fragments of bones, and pieces of wood, an item that is nowhere to be seen growing anywhere nearby, but which the Chinchorro people used to keep their mummies intact like little dolls.
The Chinchorro mummies are considered the oldest mummies in the world.
Thousands of years olde…

The Chinchorro Mummies: Resisting in the Desert
Seven thousand years ago, the Chinchorro people, along the Pacific coast of South America, began to mummify their dead. Their bodies remain hidden in the desert. This is episode 41 of Stories of Resistance.

DS-TTS: Zero-Shot Speaker Style Adaptation from Voice Clips via Dynamic Dual-Style Feature Modulation
Recent advancements in text-to-speech (TTS) technology have increased demand for personalized audio synthesis. Zero-shot voice cloning, a specialized TTS task, aims to synthesize a target speaker's voice using only a single audio sample and arbitrary text, without prior exposure to the speaker during training. This process employs pattern recognition techniques to analyze and replicate the speaker's unique vocal features. Despite progress, challenges remain in adapting to the vocal style of uns…

An AI-native experimental laboratory for autonomous biomolecular engineering
Autonomous scientific research, capable of independently conducting complex experiments and serving non-specialists, represents a long-held aspiration. Achieving it requires a fundamental paradigm shift driven by artificial intelligence (AI). While autonomous experimental systems are emerging, they remain confined to areas featuring singular objectives and well-defined, simple experimental workflows, such as chemical synthesis and catalysis. We present an AI-native autonomous laboratory, target…

A Foundation Model for Non-Destructive Defect Identification from Vibrational Spectra
Defects are ubiquitous in solids and strongly influence materials' mechanical and functional properties. However, non-destructive characterization and quantification of defects, especially when multiple types coexist, remain a long-standing challenge. Here we introduce DefectNet, a foundation machine learning model that predicts the chemical identity and concentration of substitutional point defects with multiple coexisting elements directly from vibrational spectra, specifically phonon density…

Flux Trapping Characterization for Superconducting Electronics Using a Cryogenic Widefield NV-Diamond Microscope
Magnetic flux trapping is a significant hurdle limiting reliability and scalability of superconducting electronics, yet tools for imaging flux vortices remain slow or insensitive. We present a cryogenic widefield NV-diamond magnetic microscope capable of rapid, micron-scale imaging of flux trapping in superconducting devices. Using this technique, we measure vortex expulsion fields in Nb thin films and patterned strips, revealing a crossover in expulsion behavior between $10$ and $20~μ$m strip…

First systematic experimental 2D mapping of linearly polarized $γ$-ray polarimetric distribution in relativistic Compton scattering
The interaction of photons with relativistic electrons constitutes a fundamental electromagnetic process whose polarization transfer mechanics remain incompletely characterized. We report the first systematic measurement of spatial polarization distribution for $γ$-rays generated via \SI{45}{\degree} slant inverse Compton scattering (ICS) between linearly polarized \SI{0.117}{\eV} photons and \SI{3.5}{\GeV} electrons, performing full 2D mapping of intensity, polarization angle (AOP), and degre…

EMetaNode: Electromechanical Metamaterial Node for Broadband Vibration Attenuation and Self-powered Sensing
Recent advances in mechanical metamaterials and piezoelectric energy harvesting provide exciting opportunities to guide and convert the mechanical energy in electromechanical systems for autonomous sensing and vibration control. However, practical realizations remain rare due to the lack of advanced modeling methods and interdisciplinary barriers. By integrating mechanical metamaterials with power electronics-based interface circuits, this paper makes a breakthrough with an electromechanical fr…

Generation of high power spatially-structured laser pulses via forward Raman amplification in plasma
Spatially-structured light with tunable intensity, wavelength, and spatiotemporal profiles has demonstrated significant potentials for fundamental and applied science, including the ultrafast and high-field physics. Nevertheless, the generation or amplification of such light towards extremely high power remains challenging due to the limitations of conventional gain media. Building upon our recently proposed forward Raman amplification (FRA) mechanism [Lei et al., Phys. Rev. Lett. 134, 255001 (…

Chemotaxis-Driven Instabilities Govern Size, Shape and Migration Efficiency of Multicellular Clusters
The collective chemotaxis of multicellular clusters is an important phenomenon in various physiological contexts, ranging from embryonic development to cancer metastasis. Such clusters often display interesting shape dynamics and instabilities, but their physical origin, functional benefits, and role in overall chemotactic migration remain unclear. Here, we combine computational modeling and experimental observations of malignant lymphocyte cluster migration in vitro to understand how these dyn…
